Buying a flat: survey checks and leasehold questions

Buying a flat means understanding the home itself and the wider building arrangements. A survey and your conveyancer’s work complement each other: neither automatically settles every question about condition, ownership or future shared costs.

Start with the building, not just the kitchen

A well-presented flat may still be part of a building with maintenance needs. Think about the roof, external walls, common entrances and other shared elements. Ask what can be inspected under the proposed service and which areas depend on access or the management arrangements.

A top-floor, basement or converted flat may raise different inspection questions from a straightforward middle-floor apartment. Share the floor level, construction, conversion history and any known defects when requesting a quote.

What should your survey instruction clarify?

• Which parts of the flat and building are within scope?
• Will common areas be accessible, and who arranges access?
• What limitations apply to concealed or shared components?
• Are specialist reports or further checks recommended?
• Is the proposed survey appropriate for this particular building?

A general visual survey is not a comprehensive fire-safety, cladding or services test. If building-specific safety or lender requirements arise, ask the relevant professionals which documents and specialist advice are needed.

Legal questions belong with your conveyancer

For a leasehold purchase, your conveyancer should explain the lease, remaining term, charges, restrictions and repair responsibilities. Do not infer your obligations from what a seller or agent says is normal for the building. Ask for clear answers backed by the relevant documents.

The exact legal position and current rules need property-specific advice. Government leasehold guidance can help you prepare questions, but some guidance applies to England only; buyers in Wales should check the applicable Welsh guidance with their adviser.

Look beyond the current service charge

Ask about past expenditure, reserve arrangements, proposed major works and disputes or arrears relevant to the transaction. A low current charge does not by itself mean the building has no future maintenance needs. Equally, a higher charge needs context about what it covers.

Compare total ownership costs with your budget. Shared repairs can affect affordability even when the flat’s internal decoration needs little immediate work.

Bring the two strands together

If the survey raises a concern about an external element, ask your conveyancer who is responsible and whether work is planned. If legal enquiries reveal proposed building works, ask how they relate to the observed condition. This exchange of information is more useful than treating the survey and legal process as separate tick boxes.
