Property Searches When Selling a House: What Sellers Need to Know

Most sellers assume property searches are the buyer's problem. The buyer pays for them, the buyer's solicitor orders them, and the results land with the buyer. That thinking is understandable, but it is incomplete.

What happens during the search stage directly affects whether your sale reaches exchange. Searches routinely surface issues that the seller has the responsibility to explain, document, or resolve. An unexpected planning enforcement notice, an undisclosed drainage concern, or missing certificates for building work can trigger a wave of enquiries that stalls your transaction for weeks. In some cases, it causes it to collapse.

Understanding what property searches reveal, which documents they will scrutinise, and how to prepare for the results before they arrive gives you a meaningful advantage. Sellers who are ready for the search stage move through it faster, field fewer enquiries, and reach exchange with fewer complications.

What Property Searches Are

Property searches are formal legal enquiries carried out by the buyer's solicitor during the conveyancing process. They are submitted to various authorities and organisations to reveal legal, planning, environmental, and physical issues affecting a property that would not be visible from an inspection of the building itself.

Who Orders the Searches

Searches are ordered by the buyer's solicitor, usually within the first week or two after offer acceptance, once the contract pack has been received from the seller's solicitor. The buyer pays for them, and the results are reported back to the buyer's solicitor.

The seller is not directly involved in ordering the searches, but the seller is directly affected by what they reveal. Any issue surfaced by a search will be raised as a formal legal enquiry that your solicitor must respond to on your behalf.

Why Sellers Cannot Ignore Them

Sellers who understand what each search covers are better placed to anticipate the questions that will follow. If your property has had an extension built, been affected by flooding, sits near a former industrial site, or has planning history that was not formally resolved, there is a reasonable chance the searches will surface it.

Being prepared does not mean hiding anything. It means having your documentation in order, knowing your property's history, and being ready to respond promptly and accurately when your solicitor asks for information.

The Standard Searches Carried Out on Every Sale

Several searches are conducted on virtually every residential property sale in England and Wales. Your solicitor will request these regardless of the property type, age, or location.

Local Authority Search

The local authority search is the most detailed and significant of the standard searches. It is submitted to the local council and is split into two parts: the LLC1 and the CON29.

The LLC1: Local Land Charges Register

The LLC1 checks the Local Land Charges Register held by the council. It reveals legal obligations, charges, and restrictions formally registered against the land. These can include:

• Listed building designation and any conditions attached to it

• Conservation area designation

• Outstanding financial charges registered against the property

• Tree preservation orders

• Smoke control zone designation

• Any charges arising from improvements carried out under grants

The CON29: Planning and Other Enquiries

The CON29 is a structured enquiry covering a much wider range of information. It asks the local authority specific questions about the property and its immediate surroundings. It covers:

• The planning history of the property, including any applications, decisions, and conditions

• Any planning enforcement action taken or threatened

• Whether any road adoption or road improvement schemes are proposed near the property

• Whether the property falls within a compulsory purchase area

• Any relevant proposals for development in the immediate area

What Local Authority Search Results Mean for Sellers

If the CON29 reveals a planning enforcement notice, an unapproved extension, or a condition attached to a previous permission that was never discharged, your solicitor will raise an enquiry. You will need to provide either the missing compliance evidence or a solution such as indemnity insurance.

The government target for returning local authority searches in England and Wales is ten working days. In practice, turnaround times vary considerably by council, from as little as 48 hours to several weeks in the areas with the longest queues. This is one of the most common sources of delay in the early conveyancing stage. You cannot control the speed of the local authority, but ensuring your property's planning history is clean and documented reduces the additional delay caused by follow-up enquiries.

Drainage and Water Search

The drainage and water search is submitted to the relevant water authority. It reveals how the property is connected to the mains water supply and the public sewerage network.

What It Reveals

The drainage and water search confirms:

• Whether the property is connected to the public water supply and mains drainage

• Whether there are any public sewers running within the boundary of the property

• Who is responsible for maintaining the drainage infrastructure

• Whether the water supply is metered or unmetered

Why It Matters to Sellers

If a public sewer runs through your garden, any building over or close to it requires consent from the water authority. Extensions, outbuildings, or any structural work near a sewer line that was built without consent can be flagged by the search and will generate an enquiry about compliance.

If your property uses a private drainage system such as a septic tank or sewage treatment plant rather than mains drainage, this is information you should have already disclosed in the TA6 Property Information Form. The drainage search will identify the connection status and your TA6 answers must be consistent with what the search reveals.

Sellers who are also buying their next home should plan their onward purchase finances in parallel with the sale. Understanding what your net proceeds will look like after mortgage redemption helps you set a realistic budget for what comes next.

Environmental Search

The environmental search uses detailed mapping and historical land-use data to assess risks from contamination, flooding, and ground conditions.

What It Covers

The environmental search assesses:

• Flood risk from multiple sources: rivers, surface water, groundwater, reservoirs, and coastal flooding

• Proximity to contaminated land, landfill sites, and former industrial activity

• Ground stability and subsidence risk

• Proximity to hazardous installations such as petrol stations or chemical storage sites

• Radon gas risk based on geological data

What Sellers Need to Know About Flood Risk

Flood risk is one of the most significant results that can emerge from an environmental search. If the search identifies your property as being in a flood risk zone, the buyer's solicitor will raise it. Your insurance history, any flooding events during your ownership, and any flood mitigation measures in place will all be relevant.

You are required to disclose in the TA6 whether the property has ever been affected by flooding. If it has, and you have disclosed this accurately, the search result is consistent with what you have already told the buyer. If you failed to disclose a known flood event, a search result flagging flood risk will invite scrutiny of your TA6 answers and creates significant legal risk for you as the seller.

What Sellers Need to Know About Contaminated Land

If the environmental search identifies contaminated land affecting or adjacent to your property, the buyer's solicitor will require clarification. This is more common than many sellers realise near former industrial areas, old petrol stations, tanneries, or agricultural land that was formerly used for waste disposal.

In most cases where contamination risk is flagged at a general level, the buyer's solicitor may accept a more detailed specialist report or indemnity insurance as a solution. Understand your property's history and be prepared for questions if it sits on or near land with former industrial use.

Land Registry Search

The Land Registry search confirms the current registered ownership of the property and reveals any charges, restrictions, or cautions registered against the title.

What It Confirms

The Land Registry search verifies:

• That the seller is the legal registered owner of the property being sold

• The existence and terms of any registered mortgage or charge

• Any restrictions on the title affecting how the property can be transferred

• Any cautions, notices, or entries that affect the seller's ability to sell freely

What Sellers Need to Know

Your solicitor obtains official copies of the title register at the start of the conveyancing process. The Land Registry search is then typically run again just before exchange to confirm that no new entries have been registered since the original copies were obtained.

If you have an outstanding mortgage, the redemption of that mortgage is coordinated between your solicitor and your lender as part of the completion process. Use the free Cost Saving Calculator on YooSell to understand how your net sale proceeds will look after the mortgage is redeemed and all selling costs are deducted.

Additional Searches That May Apply to Your Property

Beyond the four standard searches, additional searches are sometimes required depending on the location and history of the property.

Coal Mining Search

A coal mining search is required in areas with a history of coal extraction. This covers much of the East Midlands, South Yorkshire, County Durham, Nottinghamshire, and parts of South Wales.

What It Reveals

The coal mining search checks whether the property is in an area affected by:

• Previous underground coal mining workings

• Mine shafts, adits, or other mine entries within proximity

• Recorded past or current surface instability related to mining

• Any obligations arising from historic mining activity

When It Is Required

The Coal Authority produces a risk map that solicitors use to determine whether a coal mining search is needed. Properties in Nottinghamshire, Leicestershire, and the wider East Midlands are frequently in areas where a coal mining search is standard. If your property is in one of these areas and the buyer's solicitor has not ordered this search, it may simply mean your postcode falls outside the risk zone. Your solicitor can confirm.

Chancel Repair Search

A chancel repair search checks whether the property carries an ancient liability to contribute to the repair of the chancel of a nearby parish church. This liability dates back to medieval law and can affect properties anywhere in England and Wales where the relevant church arrangements remain in place.

Why It Still Matters in 2026

Chancel repair liability was not formally abolished and remains a legal obligation for affected properties. The liability must now be registered on the title to be enforceable against a new buyer under registration rules introduced in 2013. However, because many buyers' solicitors still include this search as standard for properties in rural areas or near historic church land, it remains a routine check.

HS2 Search

For properties within a certain distance of the HS2 railway route, an HS2 search may be required to confirm whether the property falls within any safeguarding area or is affected by the construction project.

Flood Risk Report

Where the standard environmental search identifies an elevated flood risk, the buyer's solicitor may order a more detailed standalone flood risk report. This uses more granular modelling data to assess the level of risk and the sources involved. If your property is near a river, watercourse, or in an area of known surface water flood risk, be prepared for this additional step.

How Searches Relate to the Documents You Must Provide as a Seller

The search results and the documents you provide as a seller are closely connected. Many of the enquiries generated by searches can only be resolved with the correct documentation. This section maps the key search findings to the seller documents most commonly needed to resolve them.

Planning History and Building Works Documents

The local authority search reveals your property's full planning history. If it shows an extension, outbuilding, or alteration that appears on the record without a corresponding planning permission or building regulations completion certificate, the buyer's solicitor will raise an enquiry.

What You Need to Provide

• Planning permission decision notices for any works that required consent

• Building regulations completion certificates for all applicable works

• Evidence of compliance with conditions attached to any planning permission

If you cannot locate these documents, your solicitor can advise on whether indemnity insurance is appropriate. The YooSell property guides cover the full range of documents sellers are commonly asked to provide during conveyancing, including which certificates are needed for which types of work.

Permitted Development

If works were carried out under permitted development rights and did not require formal planning permission, you can confirm this through a lawful development certificate. This document provides the buyer with formal confirmation from the local authority that the works were lawful. It is not always required but can be a practical way to resolve uncertainty about older works.

Title Deeds and Land Registry Documents

The Land Registry search confirms ownership and reveals the title register entries. As the seller, your solicitor obtains official copies of the title register and title plan at the start of the transaction.

What Sellers Need to Know

For the vast majority of registered properties, the title register and plan are obtained electronically by your solicitor at minimal cost. You do not need to locate original paper deeds. However, if your property is one of the small number of unregistered properties, original paper title deeds will be needed and your solicitor will need to trace them, which may involve your mortgage lender or a previous solicitor's file.

If the title register reveals any entry you were not expecting, such as a restriction, a right of way, or a historical covenant, your solicitor will need to explain it and the buyer's solicitor will raise it. Being aware of your title register before the sale begins allows you to discuss any unusual entries with your solicitor proactively.

EPC and Environmental Search Consistency

Your property's Energy Performance Certificate is required before marketing and must be in place before your listing goes live. The environmental search is a separate document, but the two are sometimes discussed together because both relate to the physical characteristics of the building and its land.

What Sellers Need to Ensure

Your EPC must be valid, which means it must have been produced within the last ten years by an accredited Domestic Energy Assessor. Since 15 June 2025, all new assessments are carried out under the updated RdSAP 10 methodology. If your existing certificate was produced before this date, it remains legally valid for marketing purposes until it expires, but a new assessment under RdSAP 10 may reflect recent improvements more accurately.

The environmental search does not replace or duplicate the EPC. However, if it reveals flood risk, the buyer may take a more cautious view of the property's long-term insurability and value, which can affect how offers are approached. Being transparent about the property's flood history in the TA6, and having documented evidence of any mitigation measures, is the best preparation.

Drainage Documents and the Water Search

If the drainage and water search reveals that a public sewer runs within the property boundary, or that any building has been constructed over or adjacent to it, the buyer's solicitor will raise an enquiry about whether consent was obtained from the water authority.

What You May Need to Provide

• Water authority build-over consent for any structure within the required proximity to a public sewer

• Evidence of private drainage system maintenance and compliance if the property is not on mains drainage, such as service records for a septic tank or sewage treatment plant, and evidence of compliance with current Environment Agency permit conditions

If you are unsure whether any building work on your property was subject to sewer proximity requirements, check with your solicitor before the search results arrive.

The Leasehold Management Pack and Search Results

If you are selling a leasehold property, the buyer's solicitor will review the management information pack alongside the search results. Search findings that relate to the building, such as planning entries, drainage issues affecting communal areas, or environmental risk for the whole building, are relevant to the leasehold context and may generate additional enquiries about how they are managed by the freeholder or managing agent.

What Leasehold Sellers Need to Prepare

• The original lease document or an official copy from HM Land Registry

• The TA7 Leasehold Information Form completed accurately

• The management information pack (LPE1) requested from your freeholder or managing agent as early as possible, as it typically takes two to four weeks to arrive

Building Safety for Taller Buildings

For flats in buildings above eleven metres or four storeys, building safety documentation introduced by the Building Safety Act 2022 may be relevant to search-stage enquiries. Buyers' solicitors and mortgage lenders will want to know the cladding status, whether any EWS1 assessment has been carried out, and the building's current safety certification status. If your building has gone through the EWS1 assessment process, have the certificate available. If it has not, speak to your solicitor about the current position before listing.

How to Prepare for the Search Stage Before You List

The most effective way to handle the search stage as a seller is to prepare before your property goes on the market, not after an offer is accepted. This section sets out the practical steps that reduce the risk of search results generating delays or complications.

Step One: Know Your Property's Planning History

Request a copy of your own planning history from your local council before listing. This is available as a public record and shows all applications, decisions, and enforcement notices registered against your address. Cross-reference it with the works carried out during your ownership and identify any gaps between what was done and what was formally approved.

Where gaps exist, speak to your solicitor in advance about the options, whether that is obtaining a retrospective certificate, a lawful development certificate, or arranging indemnity insurance before the buyer's search reveals the issue.

Step Two: Gather Your Building Certificates in Advance

Property searches often trigger enquiries about building certificates because searches reveal the evidence of works but not the legal compliance. Having your certificates ready before the search results arrive means your solicitor can respond to enquiries immediately rather than chasing you for documents under time pressure.

Documents to locate and pass to your solicitor before listing include:

• Planning permission decision notices for all relevant works

• Building regulations completion certificates

• FENSA or CERTASS certificates for replacement windows or doors installed since April 2002

• Gas Safe certificates for boiler installations or gas appliance work

• NAPIT or NICEIC electrical installation certificates

• Specialist contractor guarantees for damp-proofing, roofing, or structural work

• Water authority build-over consent if relevant

• For leasehold properties: the lease, management pack, and service charge records

Step Three: Review Your TA6 for Consistency with Search Results

The TA6 Property Information Form is completed by you at the start of conveyancing. The searches are then run by the buyer's solicitor, typically shortly afterwards. If your TA6 answers are inconsistent with what the searches reveal, it creates a problem.

The most common inconsistencies arise around:

• Flood history: the TA6 asks whether the property has been affected by flooding; the environmental search may reveal flood risk that prompts the buyer's solicitor to ask whether any actual flooding has occurred

• Planning enforcement: the TA6 asks about notices received; if the CON29 reveals an enforcement notice not mentioned in the TA6, the discrepancy will be raised

• Drainage: the TA6 asks about the drainage connection; if the water search reveals something inconsistent with your TA6 answer, it generates additional enquiries

Complete your TA6 accurately and thoroughly before conveyancing begins. If you are unsure what any section of the TA6 requires, your solicitor can advise on how to frame answers correctly. Sellers listing through YooSell's pricing plans also have access to integrated conveyancing support from the moment an offer is accepted.

Step Four: Instruct Your Solicitor Early

The search results and the enquiries that follow cannot be dealt with effectively without a solicitor in place. Many sellers wait until after an offer is accepted to instruct a conveyancer. This means the first two weeks of the transaction are spent setting up the file rather than progressing it.

If you instruct your solicitor before your property is listed, they can begin gathering title documents, preparing the contract pack, and checking the TA6 in advance. When a buyer is found and the searches are ordered, your solicitor is already fully briefed and can respond to results quickly.

How to Handle Enquiries Generated by Search Results

When the searches return results that raise questions, the buyer's solicitor sends formal written enquiries to your solicitor. These must be answered clearly and promptly. The quality of your responses directly affects how long the enquiries stage takes.

Responding Quickly

Every day a formal enquiry sits unanswered is a day added to the overall transaction timeline. When your solicitor contacts you with an enquiry arising from a search result, respond the same day if possible. If you need to locate a document, start that process immediately and keep your solicitor updated on progress.

Being Specific and Accurate

Vague answers to enquiries generate follow-up questions. A response such as "we believe planning permission was obtained at some time" is not sufficient. The buyer's solicitor needs either the document itself or a clear explanation of why it is not available and what alternative solution is being proposed.

If you do not have a document that is being requested, do not delay telling your solicitor. The options, whether indemnity insurance, a specialist report, or an application to the local authority, can only be assessed and actioned once your solicitor knows the document is missing.

Using Indemnity Insurance to Resolve Missing Documentation

Indemnity insurance is a widely used and legally accepted solution for a range of documentation issues that arise during the search and enquiries stage. It is a one-off policy that protects the buyer against any financial loss arising from a specific identified risk.

Common uses include:

• Missing planning permission where enforcement action is now time-barred

• Missing building regulations completion certificate

• Missing FENSA certificate where the installer can no longer be traced

• Chancel repair risk

• Unregistered easements or rights of way

• Missing build-over consent for drainage works

The cost is typically modest and is usually paid by the seller as part of the transaction. Your solicitor will advise whether indemnity insurance is appropriate for any specific issue and will obtain quotes on your behalf.

Search Delays and What Sellers Can Do

Local authority search turnaround times are one of the most common sources of delay in property transactions in England and Wales. Some councils return results within 48 hours. Others, particularly during busy periods or when facing staff shortages, have been known to take five to six weeks or longer.

What Causes Delays

The main factors affecting search turnaround time are:

• The volume of searches being processed by the local authority at the time

• Whether results are returned electronically or by post

• Seasonal demand levels, which tend to be higher in spring and autumn

• Staffing levels at individual councils

Personal Searches as an Alternative

Your solicitor may offer to use a personal search company rather than submitting the search directly to the local authority. Personal search companies retrieve the data from the local authority's own records but operate independently and can often return results faster.

Personal searches are accepted by most mortgage lenders when supported by search indemnity insurance. If speed is a priority and your local authority is known for delays, discuss the personal search option with your solicitor at the outset.

What Sellers Can Do While Searches Are Pending

The searches are run in parallel with other conveyancing steps. While they are being processed, your solicitor can still:

• Raise and respond to initial contractual enquiries

• Progress the title investigation

• Arrange the mortgage redemption statement

• Agree the draft contract

Staying responsive during this period keeps all other elements of the transaction moving so that when the search results arrive, only the search-specific enquiries remain to be resolved.
