Searches Explained When Buying a Property

At Towerstone, we provide specialist property accountancy services for homeowners, landlords, and property investors. We have written this article to explain what searches are and why they matter, helping you make informed decisions.

When you buy a house in the UK, one of the least visible but most important parts of the legal process is property searches. Buyers often hear their solicitor say “we’re waiting for the searches” without really understanding what that means, why they matter, or what could go wrong if they are skipped or delayed.

Searches are not about the condition of the house you can see. They are about risks you cannot see by viewing the property. They protect you from legal, financial, environmental, and practical problems that might only become apparent after you move in, when it is often too late.

In this guide, I will explain clearly what searches are, why they are needed, the different types of searches, how long they take, what they can reveal, and what happens if issues come up. This is written in clear UK English and reflects how conveyancing works in real life rather than in theory.

What Searches Actually Are

Property searches are formal checks carried out by your solicitor during the conveyancing process. They involve requesting information from local authorities, water companies, and other bodies to uncover issues that affect the property or the land it sits on.

Searches are designed to answer questions such as:

Is the property legally allowed to be used as it is?

Are there any restrictions on the land?

Are there plans nearby that could affect value or enjoyment?

Are there environmental or flooding risks?

Are roads and drains properly adopted and maintained?

These are things you cannot reliably find out yourself.

Why Searches Are So Important

Searches exist to protect buyers.

Without searches, you could buy a house and later discover:

A road outside is private and you must pay to maintain it

An extension was built without planning permission

A new road, railway, or development is planned next door

The property is at high flood risk

You are responsible for an unexpected legal obligation

Most of these issues do not show up during viewings or surveys.

Once you complete the purchase, you usually take the property as is, including any hidden problems.

Are Searches a Legal Requirement?

Searches are not legally mandatory in the sense that there is no law forcing you to have them.

However, in practice:

Mortgage lenders require searches

Solicitors will strongly advise against skipping them

Buying without searches exposes you to serious risk

If you are buying with a mortgage, searches are effectively compulsory because the lender insists on them to protect their security.

The Main Types of Searches

There are several different searches, but three core searches are almost always carried out.

Local Authority Search

The local authority search is the most important and most detailed search.

It checks records held by the local council and covers things like:

Planning permissions and refusals

Building regulations approval

Enforcement notices

Conservation areas

Listed building status

Tree preservation orders

Road schemes and traffic plans

This search tells you whether the property complies with planning rules and whether the council has any powers that could affect it.

Why the Local Authority Search Matters

Many buyers assume planning issues would already have been dealt with, but that is not always true.

Common problems uncovered include:

Extensions built without proper approval

Conditions attached to past planning permissions

Breaches that could be enforced against a new owner

Roads not maintained by the council

These issues can affect mortgage approval, resale value, and your legal responsibility.

Drainage and Water Search

The drainage and water search is usually carried out with the local water company.

It confirms:

Whether the property is connected to mains water

Whether it is connected to mains drainage

Who owns and maintains the sewers

Whether there are public drains within the boundaries

This search is particularly important if you are planning future building work.

Why Drainage Searches Matter

If there is a public sewer running through your garden, you may need permission to build over it.

If the property is not connected to mains drainage, you may be responsible for maintaining a septic tank or private system, which comes with legal and environmental obligations.

These are not issues most buyers expect to discover after moving in.

Environmental Search

The environmental search looks at risks associated with the land and surrounding area.

It typically covers:

Flood risk

Land contamination

Ground stability

Proximity to landfill sites

Industrial use history

This search does not inspect the property. It uses data and modelling to assess risk.

Why Environmental Searches Matter

Environmental issues can be expensive and difficult to resolve.

For example:

Flood risk can affect insurance availability and cost

Contaminated land can lead to clean up obligations

Ground stability issues can affect mortgage lending

Even if a property has never flooded, being in a risk zone can still have consequences.

Additional Searches That May Be Needed

Depending on location and property type, additional searches may be recommended.

These can include:

Chancel repair liability searches

Mining searches for coal, tin, or brine

High speed rail searches

Commons registration searches

Your solicitor will advise if these are relevant based on the property’s location.

What Searches Do Not Cover

It is important to understand what searches do not do.

Searches do not:

Check the physical condition of the house

Identify structural defects

Confirm boundaries physically

Replace a survey

That is why searches and surveys work together. One looks at legal and environmental risk, the other looks at physical condition.

How Long Do Searches Take?

Search times vary depending on the local authority and the type of search.

Typical timeframes are:

One to two weeks in faster areas

Two to four weeks in average areas

Longer in busy councils or complex cases

Delays are common and usually outside your solicitor’s control.

Can Searches Delay the Purchase?

Yes, searches can delay a purchase, but they are rarely the only cause.

Searches usually run alongside:

Mortgage processing

Surveys

Enquiries

Most delays come from a combination of factors rather than searches alone.

What Happens When Searches Come Back?

Once search results are received, your solicitor reviews them and raises enquiries if anything needs clarification.

This might include:

Asking the seller for planning documents

Requesting indemnity insurance

Advising you about future risks

Not all search results are black and white. Some require judgement rather than action.

Are Search Results Ever a Deal Breaker?

Occasionally, yes.

Searches can reveal issues serious enough to stop a purchase, such as:

Major enforcement action

Unacceptable flood risk

Legal restrictions that prevent intended use

However, this is rare. More often, issues lead to negotiation or additional protection rather than withdrawal.

Can You Buy Without Searches?

If you are buying with cash, you can technically choose to proceed without searches.

However, this is risky and usually discouraged.

Skipping searches means you accept all unknown risks. Many buyers who skip searches do so to save time or money, but the potential cost of a missed issue is far greater than the cost of the searches.

How Much Do Searches Cost?

Search costs vary by area but are usually in the region of:

£250 to £400 for standard searches

This is a small proportion of the overall purchase cost and generally good value for the protection they provide.

Can You Speed Searches Up?

Some councils offer expedited services, and some solicitors use personal search providers.

These can be quicker, but availability and reliability vary.

Even with faster searches, delays elsewhere in the process can still occur.

Common Misunderstandings About Searches

Many buyers think searches duplicate surveys, which they do not.

Others assume searches only matter for new builds or older properties, which is not true.

Some buyers also think searches guarantee there will be no problems, but they only reveal what is recorded or reasonably known.

Searches reduce risk, they do not eliminate it entirely.

My Professional View

In my professional experience, searches are one of the most important safeguards in the buying process.

They rarely create problems, but they regularly prevent problems by highlighting issues before you commit legally.

Buyers who question the value of searches usually change their mind when they see what can come up.

Final Thoughts

So, what are searches when buying a house in the UK?

Searches are legal and environmental checks carried out by your solicitor to uncover issues that are not visible during viewings or surveys. They cover planning, drainage, environmental risk, and other hidden factors that could affect your ownership, finances, or enjoyment of the property.

They are not just paperwork. They are protection.

While searches can add time and cost to the process, they exist to stop you buying a house with problems you did not know about. In most cases, that protection is well worth the wait.
