What Property Searches Do You Need When Buying a House in London?
When you're buying a property, it's natural to focus on what you can see, the location, layout, condition and whether it feels like the right home.
However, some of the most important information about a property isn't immediately visible.
Property searches form an important part of the conveyancing process, helping uncover information about the property and surrounding area that could affect your purchase, your future plans or potentially the property's value.
At AK Law Solicitors, our Residential Property team supports buyers across London and the surrounding areas throughout the conveyancing process. In this guide, we explain the main property searches you may encounter, what they can reveal and what happens if a potential issue is identified.
What Are Property Searches?
Property searches are enquiries made with local authorities and other organisations to obtain information about the property you are planning to buy.
Your solicitor will review the results alongside the other legal documentation relating to the property and advise you if anything requires further investigation.
If you're purchasing with a mortgage, your lender will generally require certain searches to be completed. Cash buyers are not necessarily required to carry out the same searches, but proceeding without them can mean purchasing a property without important information that might otherwise have been identified.
The exact searches required will depend on the property, its location, your mortgage lender and the circumstances of your purchase.
1. Local Authority Search
The local authority search is one of the main searches carried out during a residential property purchase.
It provides information held by the relevant local authority that may affect the property.
This can include matters such as:
Planning decisions relating to the property
Building regulations information
Planning restrictions
Conservation area status
Tree preservation orders
Enforcement notices
Proposed road schemes
Whether roads serving the property are publicly maintained
Other local land charges or restrictions affecting the property
This information can be particularly important if you're planning to extend, renovate or otherwise alter the property after you move in.
For example, a search could reveal that previous alterations were subject to planning or building regulation requirements, or that restrictions apply which could affect what you are able to do with the property in future.
Your solicitor will review the results and advise you about any matters that need further investigation.
2. Environmental Search
An environmental search looks at environmental factors that could potentially affect the property or land.
Depending on the search provider and report obtained, this can include information relating to:
Contaminated land
Previous industrial use
Landfill sites
Ground stability
Radon
Flooding and other environmental risks
This can be particularly relevant in London, where land may have had a variety of historical uses before residential properties were built.
If an environmental search identifies a potential concern, it does not automatically mean that you should not proceed with the purchase. Your solicitor can explain the result and advise whether additional enquiries, reports or specialist advice may be appropriate.
3. Water and Drainage Search
A water and drainage search provides information about the property's connection to mains water and sewerage services.
It can help establish matters such as:
Whether the property is connected to mains water
Whether it is connected to the public sewer system
The location of public sewers and drains
Whether a public sewer runs within the boundaries of the property
How the property's water supply is charged
Knowing where public drains and sewers are located can be particularly important if you're considering extending or developing the property in the future.
For example, building close to or over certain sewers may require additional permissions or agreements.
4. Flood Risk Search
Flooding isn't something buyers necessarily associate immediately with purchasing a London property, but flood risk can take several different forms.
Depending on the property and information already available through other searches, further flood-risk information may be recommended.
This could consider potential risks from:
Rivers
Surface water
Groundwater
Reservoirs
Sewer flooding
Understanding flood risk is important not only because of the potential impact on the property itself but also because it may affect buildings insurance, mortgage lending and the future saleability of the property.
If a potential flood risk is identified, further investigation may be recommended before you proceed.
5. HM Land Registry Checks
Your solicitor will also review the property's registered title through HM Land Registry.
This is an essential part of establishing that the seller is entitled to sell the property and understanding exactly what you will be purchasing.
The title documentation can provide important information about:
The registered owner
The extent of the property
Rights benefiting the property
Rights affecting the property
Restrictive covenants
Mortgages or other registered charges
Your solicitor will review the title carefully and raise enquiries if anything requires clarification.
6. Additional Location-Specific Searches
Not every property requires exactly the same searches.
Depending on where the property is located and the issues associated with the land, your solicitor or mortgage lender may recommend additional searches.
These could include searches relating to matters such as:
Mining activity
Ground stability
Infrastructure
Transport schemes
Specific environmental risks
Other issues relevant to the property's location
This is one reason why conveyancing should not simply be approached as a standard checklist. Your solicitor will consider the particular property you are buying and advise which searches are appropriate.
What Can Property Searches Uncover?
Property searches can reveal information that you may not discover from an estate agent's particulars or from viewing the property.
For example, searches might identify:
Planning or building regulation issues
Restrictions affecting the property
A proposed road or infrastructure project
Potential contaminated land
Flood risk
Drainage or sewer issues
Environmental concerns
Matters that could affect future alterations to the property
Importantly, a property search is different from a survey.
Searches primarily investigate legal, environmental and infrastructure information held by authorities and other organisations. A property survey, on the other hand, assesses the physical condition of the building and may identify issues such as damp, structural problems or defects.
Both can play an important role in helping you understand exactly what you're buying.
What Happens if a Search Reveals a Problem?
A concerning search result doesn't necessarily mean that your purchase cannot proceed.
The next step will depend on what has been identified.
Your solicitor may:
Raise additional enquiries with the seller's solicitor
Request further documentation
Recommend an additional or more detailed search
Ask for evidence of relevant planning or building regulation approvals
Recommend obtaining specialist advice
Discuss whether an appropriate solution can be put in place
Report the matter to your mortgage lender where required
In some circumstances, the information discovered may influence your decision about whether to proceed with the purchase.
The important thing is that potential issues are identified and properly considered before you become legally committed to buying the property.
How Long Do Property Searches Take?
The time required to obtain property searches can vary depending on the local authority, search provider, property and searches required.
Some results may be returned relatively quickly, while others can take longer.
This is another reason why instructing your conveyancing solicitor as soon as your offer is accepted can be beneficial. Searches can be ordered at an early stage, helping to keep the transaction moving while the other legal work is being carried out.
How Much Do Property Searches Cost?
The cost of property searches varies depending on the property, location, search provider and number of searches required.
As a general guide, a standard residential search package may cost approximately £400–£500, although additional or specialist searches can increase the overall amount.
Your solicitor should explain which searches are recommended for your property and provide details of the relevant costs before they are ordered.

Do Cash Buyers Need Property Searches?
If you're buying a property without a mortgage, you may have more flexibility over which searches you choose to carry out because there is no mortgage lender imposing its own requirements.
However, choosing not to carry out searches means potentially proceeding without information that a search could have revealed.
Considering the value of a property purchase, particularly in London, searches can provide valuable information before you make a legally binding commitment.
Your solicitor can explain the searches available and help you make an informed decision based on the property and your circumstances.
Why Property Searches Matter
Buying a property is a significant financial commitment, and searches are an important part of understanding what you're purchasing before you exchange contracts.
While no search can provide an absolute guarantee that a property will never experience a problem, they can identify information that might otherwise remain undiscovered until after you become the legal owner.
Combined with a careful review of the property's title, enquiries of the seller and an appropriate survey, searches can help you approach your purchase with greater confidence.
