Property Searches Explained: What They Are and Why They Matter

If you're buying or selling a home in England or Wales, property searches are one of the most important — and most misunderstood — parts of the process. They happen during conveyancing, and they're one of the main reasons it takes as long as it does.

This guide explains exactly what property searches are, why they're done, what each type covers, and how much you should expect to pay. Whether you're a first-time buyer trying to understand the process, or a seller looking to get ahead of delays, this is everything you need to know.

What are property searches?

Property searches are a set of checks carried out as part of the conveyancing process when a property is being bought or sold. Their purpose is to uncover any hidden issues that could affect the property's value, your ability to use it, or your legal rights as an owner.

Searches are typically ordered by the buyer's solicitor or licensed conveyancer after an offer has been accepted. The results come from local authorities, utility companies, environmental data providers, and public registries including HM Land Registry.

Think of searches as a background check on the property itself. A survey tells you about the building's physical condition. Searches tell you about everything around and underneath it — the legal, environmental, and infrastructure context that could affect you as the owner.

According to the Law Society's Conveyancing Protocol, a standard set of searches should be carried out on every residential transaction. Most mortgage lenders make this a condition of lending.

Why are property searches important?

Without searches, you could unknowingly buy a property that sits on contaminated land, is at serious risk of flooding, has a planned motorway running through the garden, or is liable for thousands of pounds in chancel repair costs.

Searches protect buyers from nasty surprises by revealing issues before contracts are exchanged. Once you exchange, you're legally committed — so any problems discovered afterwards are yours to deal with.

For sellers, understanding searches is just as important. Issues flagged in searches are one of the top reasons house sales fall through. If you know what the buyer's solicitor will find, you can address potential concerns before they become deal-breakers.

Who pays for property searches?

Traditionally, the buyer pays for property searches. They form part of the conveyancing disbursements — the third-party costs your solicitor passes on to you. You can see a full breakdown in our conveyancing costs guide.

However, there is a growing trend for sellers to order searches upfront, before the property even goes on the market. This is sometimes called a "seller's search pack" or "upfront information pack." The logic is simple: if the searches are already done when the buyer makes an offer, you eliminate one of the biggest sources of delay in the entire process.

The National Trading Standards Estate and Letting Agency Team has been actively promoting upfront information through its Material Information in Property Listings guidance, encouraging sellers and agents to provide more transparency from day one. Pine is built around this principle — helping sellers get their legal paperwork and searches done before listing, so sales move faster and fall-throughs are less likely.

What property searches are done when buying a house?

The exact searches ordered will depend on the property's location, but a standard residential transaction in England and Wales typically includes the following.

Local authority search (LLC1 and CON29R)

The local authority search is the most important — and the slowest — search in the standard pack. It actually consists of two parts:

LLC1 (Local Land Charges Register search) — This reveals any financial charges or restrictions registered against the property by the local authority. Examples include listed building status, tree preservation orders, smoke control zones, and planning enforcement notices. The LLC1 is maintained under the Local Land Charges Act 1975 and is gradually being migrated to HM Land Registry's digital register.
CON29R (required enquiries) — This is a standard set of questions put to the local council covering planning decisions, building control records, road adoption status, contaminated land entries, and more. The form is published by the Law Society and is uniform across all local authorities.

There is also an optional CON29O form covering additional enquiries — such as nearby public paths, common land, or environmental notices — which your conveyancer may recommend depending on the property.

Typical cost: £80-£150 (varies significantly by council).
Typical turnaround: 2-6 weeks. Some councils (particularly in London) can take 8 weeks or longer during busy periods.

This search is the single biggest cause of conveyancing delays. That's why ordering it early — even before you have a buyer — can make such a big difference to your overall conveyancing timeline.

Drainage and water search

This search is submitted to the relevant water and sewerage company (such as Thames Water, Severn Trent, or United Utilities) and reveals:

Whether the property is connected to the public mains water supply and public sewer
The location of public sewers and water mains near or under the property
Whether any public sewers run through the property boundaries (which can restrict what you build)
Whether the water charges are metered or unmetered
Whether there are any adoption agreements for sewers serving the property

Under the Water Industry Act 1991, water companies have a right to access and maintain public sewers. If a public sewer runs under your garden or extension, you could face significant restrictions on building work — or even be required to move structures at your own cost.

Typical cost: £40-£70.
Typical turnaround: 5-10 working days.

Environmental search

The environmental search checks for contamination, flooding, and ground stability risks. It is compiled from data held by the Environment Agency, the British Geological Survey, and other sources. A standard environmental search typically covers:

Contaminated land — Has the site or nearby land ever been used as a landfill, petrol station, factory, or other potentially polluting activity? Under Part 2A of the Environmental Protection Act 1990, local authorities can require property owners to pay for clean-up of contaminated land.
Flood risk — Is the property in a flood zone? Data comes from the Environment Agency's flood maps, which classify areas into Flood Zones 1 (minimal risk) through 3 (high risk). Properties in Flood Zone 3 may struggle to get buildings insurance.
Ground stability — Is the property at risk of subsidence from natural causes such as clay shrinkage, old mines, or sinkholes? The British Geological Survey provides geological hazard data that feeds into this assessment.
Radon gas — Is the property in an area where radon (a naturally occurring radioactive gas) is present at elevated levels? Public Health England (now UKHSA) maintains a radon risk map.
Energy and infrastructure — Proximity to overhead power lines, substations, phone masts, and other installations.

Typical cost: £30-£60.
Typical turnaround: 24-48 hours (these are electronic data searches).

Chancel repair liability search

This one surprises many buyers. Under a medieval law that was never fully repealed, owners of certain properties in England and Wales can be liable for the cost of repairing the chancel (the area around the altar) of their local parish church. The liability can run into tens of thousands of pounds.

The Land Registration Act 2002 allowed churches to protect this right by registering a notice on the Land Registry title. The deadline for registration was 12 October 2013. If no notice was registered by that date, the liability is not enforceable against a new purchaser for value — but only if the property is registered land.

A chancel repair liability search checks whether a notice has been registered against the title. Given the potential cost of a chancel repair claim, this small search is well worth doing.

Typical cost: £4-£25.
Typical turnaround: Same day (electronic search).

Mining search (CON29M)

If the property is in a coal mining area, a CON29M search is submitted to the Coal Authority. It reveals whether the property is in an area of past, present, or future coal mining activity, including:

Past underground and opencast mining
Mine entries (shafts and adits) near the property
Claims for subsidence damage
Coal mining geology and ground stability issues
Any mining-related hazards

The Coal Authority publishes an interactive map showing coal mining reporting areas. Roughly 42% of properties in England fall within a coal mining reporting area. If yours does, your conveyancer will almost certainly recommend this search.

Typical cost: £40-£55.
Typical turnaround: 1-3 working days (electronic).

In areas with other types of mining history — tin, lead, brine, or limestone — your conveyancer may recommend alternative mining searches from commercial providers.

Land Registry title search

Strictly speaking, this is not part of the "search pack" but it is one of the first things any conveyancer does. The buyer's solicitor will obtain the official copy of the title register and the title plan from HM Land Registry. These documents confirm:

Who legally owns the property
The boundaries of the property (on the title plan)
Whether the property is freehold or leasehold
Any restrictions, covenants, or charges on the title
Any rights of way or easements
Whether there is a mortgage registered against the property

You can download these documents yourself from the HM Land Registry online portal for £3 per document (as of 2026). Your conveyancer will normally obtain them on your behalf and include the cost in their disbursements.

Typical cost: £3-£7 per document.
Typical turnaround: Instant (online).

Flood risk assessment

While flood risk data is included in the standard environmental search, some conveyancers or mortgage lenders may request a more detailed standalone flood risk report. This provides a property-specific assessment using:

Environment Agency flood zone data — The official classification of flood risk for the area
Surface water flood risk — The risk of flooding from heavy rainfall overwhelming drainage systems
Groundwater flooding risk — The risk of water rising from below ground level
Historic flood data — Whether the property or surrounding area has flooded before
Flood defences — Whether the area is protected by existing flood defence infrastructure

You can check basic flood risk for free on the Gov.uk flood risk service (check-long-term-flood-risk.service.gov.uk), but the paid reports provide far more detail and are what lenders and solicitors work from.

Typical cost: Included in environmental search, or £10-£30 as a standalone report.
Typical turnaround: Same day (electronic).

Property search costs and timelines: comparison table

Here is a summary of the standard property searches, their typical costs, and how long they take to come back. All figures are indicative and reflect 2026 pricing in England and Wales.

Search type	Typical cost	Turnaround	What it covers	When needed
Local authority (LLC1 + CON29R)	£80-£150	2-6 weeks	Planning, building control, road adoption, charges, restrictions	Every transaction
Drainage and water	£40-£70	5-10 working days	Public sewer and water mains location, connections, adoption status	Every transaction
Environmental	£30-£60	24-48 hours	Contamination, flood risk, ground stability, radon, energy infrastructure	Every transaction
Chancel repair liability	£4-£25	Same day	Liability for parish church chancel repairs	Every transaction
Mining (CON29M)	£40-£55	1-3 working days	Past and present coal mining activity, subsidence, mine entries	Coal mining areas only
Land Registry title	£3-£7	Instant	Ownership, boundaries, covenants, restrictions, charges	Every transaction
Flood risk (standalone)	£10-£30	Same day	Detailed flood zone classification, surface water and groundwater risk	If lender requires or high-risk area

Total for a standard search pack: £250-£450 depending on location, provider, and whether a mining search is needed. This figure excludes any handling fee your solicitor may charge for ordering and reviewing the results.

What happens if searches reveal problems?

Finding an issue in a search does not automatically mean the sale is over. In fact, most searches flag at least one point that needs further discussion. What matters is how the issue is handled.

Here is the typical process when a problem is found:

The buyer's solicitor raises enquiries. They will write to the seller's solicitor asking for more information or clarification. For example, if the local authority search shows a nearby planning application, they may ask what it is and whether it affects the property.
The seller provides answers. Your solicitor will ask you to respond. This is where having completed your TA6 form thoroughly pays off — many enquiries can be answered by referring back to the information you've already provided.
The parties negotiate a resolution. Depending on the severity of the issue, the buyer may ask for a price reduction, request that the seller takes out indemnity insurance, or ask for the problem to be fixed before exchange.
In rare cases, the buyer withdraws. Serious issues — such as a major flood risk, contaminated land requiring remediation, or a planning decision that fundamentally affects the property — can cause a buyer to pull out entirely. This is one of the key reasons sales fall through.

The best defence as a seller is knowledge. If you know what the searches will reveal, you can prepare your answers in advance and avoid the slow back-and-forth that causes delays.

Can you do property searches before selling?

Yes — and it is one of the smartest things you can do as a seller.

Ordering searches upfront means that when your buyer's solicitor requests them, you can provide the results immediately instead of waiting 2-6 weeks for the local authority to respond. This alone can shave weeks off your conveyancing timeline.

There are a few things to bear in mind with upfront searches:

Shelf life: Most mortgage lenders accept search results that are 3-6 months old. If your property takes longer than this to sell, you may need to refresh certain searches.
Buyer acceptance: Some buyer solicitors may want to order their own searches rather than rely on seller-commissioned ones. However, if your searches are from a regulated provider and come with insurance, most will accept them.
Cost: You are paying for the searches upfront rather than the buyer paying later. The cost is typically £250-£450, which many sellers consider worthwhile for the speed advantage.

Pine helps sellers order searches at near-trade prices as part of getting sale-ready before listing. Combined with completing your TA6 and TA10 forms early, this can make your property significantly more attractive to buyers and their solicitors.

Personal searches vs official searches

When it comes to local authority searches, there are two routes: official and personal.

Official searches

An official search is submitted directly to the local authority. The council processes the enquiry and returns the results with a statutory guarantee. If the information they provide turns out to be incorrect, the buyer has a right to compensation under the Local Land Charges Act 1975.

Official searches are the gold standard and are accepted by all mortgage lenders without question. The downside is speed — they are subject to the council's processing times, which can be lengthy.

Personal searches

A personal search is carried out by a search agent (or by you in person) who inspects the records held by the local authority. The agent then compiles the results into a report. Personal searches are typically faster and cheaper than official searches, but they do not carry the same statutory guarantee.

To bridge this gap, most reputable personal search companies offer insurance-backed search reports. These are regulated by the Council of Property Search Organisations (CoPSO) or the Property Codes Compliance Board (PCCB), and the insurance provides cover if the results are inaccurate.

Most mortgage lenders now accept regulated personal searches with insurance, but it is worth checking with your buyer's lender before relying on them.

How to read property search results

Search results can look dense and technical, but they generally follow a consistent format. Here is what to look for in each type:

Reading a local authority search

LLC1 entries: Any entry here means there is a charge or restriction registered against the property. Common examples include tree preservation orders, listed building status, or a financial charge from the council. "Nil" means nothing is registered.
CON29R results: Each question is answered individually. Look for any "yes" answers, which indicate something has been flagged — such as a planning application within 200 metres, an adopted road, or a building control completion certificate.

Reading a drainage search

Check whether the property is connected to the public sewer. Private drainage (such as a septic tank) can involve additional maintenance responsibilities.
Look for any public sewers shown running through or near the property boundary. Building within 3 metres of a public sewer requires approval from the water company.

Reading an environmental search

Results are usually colour-coded: green (pass/low risk), amber (moderate risk — further investigation recommended), red (fail/high risk — action required).
Pay particular attention to the flood risk and contamination sections. An amber or red result does not necessarily mean you should not proceed, but your solicitor should investigate further.

Your conveyancer will review all search results and flag anything that needs your attention. You should not need to interpret the results yourself, but understanding the basics helps you ask the right questions.

How search results affect the house sale

In most transactions, search results confirm what everyone already expects — no major issues, and the sale proceeds normally. But when searches do flag something, the impact depends on what was found and how it is handled.

Minor issues (e.g. a nearby planning application for a house extension, a tree preservation order) are usually noted and accepted. They rarely affect the sale.
Moderate issues (e.g. a public sewer under the property, a moderate flood risk score) may prompt the buyer to request indemnity insurance or a modest price adjustment.
Serious issues (e.g. the property sits on a former landfill site, major subsidence risk, or Flood Zone 3 classification) can lead to significant renegotiation, difficulty obtaining a mortgage, or the buyer withdrawing.

The key for sellers is transparency. If you already know about an issue — whether from your own searches or from living in the property — disclosing it early in the TA6 form is far better than having it discovered later. Surprises erode trust and are more likely to cause a sale to collapse.

How to speed up property searches

Given that searches are one of the main causes of delay in the conveyancing process, anything you can do to speed them up is worth considering. Here are practical steps for both buyers and sellers:

If you're a seller

Order searches before you list. This removes the wait entirely for your buyer. Pine can help you do this at near-trade prices.
Complete your TA6 form thoroughly. Many post-search enquiries arise because the buyer's solicitor wants information the seller should have provided upfront.
Get your title documents ready. Download your title register and title plan from HM Land Registry so your conveyancer has them from day one.
Be proactive about known issues. If you know about a problem (flooding, planning, boundary disputes), disclose it early and have your explanation ready.

If you're a buyer

Instruct your solicitor early. Do not wait until your offer is accepted to start looking for a conveyancer.
Ask your solicitor to order searches immediately. Some solicitors wait until other checks are done before ordering searches. Ask them to submit the searches on day one.
Ask the seller if they have upfront searches. If the seller has already done a search pack, your solicitor can review the results immediately rather than ordering fresh ones.
Consider regulated personal searches. If the local authority has long turnaround times, a regulated personal search with insurance can be returned in days rather than weeks.

Frequently asked questions

How much do property searches cost in total?

A standard pack of property searches (local authority, drainage and water, environmental, and chancel repair) typically costs between £250 and £450 in total, depending on location and provider. Individual searches range from £4 for a chancel repair check to £150 or more for a local authority search. Your conveyancer may add a small handling fee on top.

How long do property searches take to come back?

Most property searches take between 2 and 6 weeks, with the local authority search being the slowest. Drainage and water searches usually return within 5-10 working days, environmental searches within 24-48 hours, and chancel repair searches within 24 hours. Some local authorities now offer expedited searches for an additional fee.

Who pays for property searches — buyer or seller?

Traditionally, the buyer pays for property searches as part of their conveyancing disbursements. However, sellers can order searches upfront before listing to speed up the sale process. The buyer's solicitor may still want to verify or re-order certain searches, but having them ready can cut weeks off the timeline and make your property more attractive.

Can I do property searches myself?

Yes, you can conduct personal searches yourself by visiting the local authority offices or using the Gov.uk online portal. Personal searches are cheaper (sometimes free) but are not insured and may not be accepted by mortgage lenders. Most conveyancers recommend official (or regulated) searches because they come with insurance-backed guarantees.

Do property searches expire?

Property searches do not have a fixed legal expiry date, but most mortgage lenders consider them valid for 3 to 6 months from the date of issue. If your sale takes longer than this, your buyer's lender may require updated searches, which means additional cost and delay. This is another reason to avoid unnecessary hold-ups after accepting an offer.

What happens if property searches reveal a problem?

If searches reveal an issue — such as a planning application nearby, flood risk, or contaminated land — it does not automatically stop the sale. The buyer's solicitor will raise enquiries asking the seller to explain or address the issue. Depending on severity, the buyer may renegotiate the price, request indemnity insurance, ask for remedial work, or in some cases withdraw from the sale.

Are property searches compulsory when buying a house?

Property searches are not legally compulsory, but they are effectively required in practice. Any mortgage lender will insist on at least a local authority search and an environmental search before releasing funds. Even cash buyers are strongly advised to carry out searches to avoid buying a property with hidden legal or environmental problems.

Can a seller order property searches before selling?

Yes, and it is increasingly common. Sellers can order a full search pack upfront — including local authority, drainage, environmental, and chancel searches — before they even list the property. This is known as upfront or seller-commissioned searches. It removes one of the biggest bottlenecks in the conveyancing process and can reduce the time from offer to completion by several weeks.

What is the difference between a personal search and an official search?

An official search is submitted directly to the local authority or utility company and comes with an insurance-backed guarantee protecting the buyer if the results are incorrect. A personal search is carried out by a search agent who inspects the local authority records themselves. Personal searches are faster and cheaper but do not carry the same statutory protection, and some mortgage lenders will not accept them.

Do I need a mining search when buying a property?

A mining search is only needed if the property is in an area with a history of coal mining or other mineral extraction. The Coal Authority maintains a map of affected areas covering parts of England, Scotland, and Wales. If your property falls within a coal mining reporting area, your conveyancer will recommend a CON29M mining search, which typically costs around £40-£55.
