Buying a London flat means acquiring a leasehold interest in a home that depends on a larger building. Internal condition matters, but so do the roof, façade, structure, communal services, management arrangements and future maintenance costs. No single professional checks all of these matters in the same way.
The buyer’s surveyor assesses visible condition within the agreed scope. The conveyancer interprets the lease, management information, service charges, notices and legal responsibility. Their findings should be considered together before exchange.
What the survey can inspect
The surveyor inspects the flat and accessible parts of the building relevant to the agreed service. Access to roofs, plant rooms, other flats and concealed construction is often restricted. The report should identify limitations and explain material visible concerns.
A normal home survey is not automatically a structural investigation of the entire block. Specialist advice may be recommended for movement, cladding, services or other complex issues.
What the conveyancer should investigate
The lease defines the premises, remaining term, ground rent, repair obligations, insurance arrangements, alteration controls and rights over common parts. The management pack can reveal budgets, accounts, reserve funds, disputes and planned works.
The Leasehold Advisory Service warns buyers to check major works and how they will be funded. A healthy reserve can reduce large one-off demands, but the documents need professional review.
Link defects to responsibility
If the survey identifies roof leakage, failing windows, cracking or damp, the buyer needs to know who must repair it and how the cost is shared. The physical diagnosis alone does not answer the contractual question.
Send the relevant survey section to the conveyancer and ask targeted enquiries. Where planned works exist, compare their scope with the survey findings rather than assuming they solve every defect.
Building safety and insurance
Some blocks require additional building-safety, fire or cladding information. Requirements depend on the building and transaction. The surveyor should not promise lender acceptance, and the conveyancer should check current documentation and statutory responsibilities.
The survey reports conditions observed on its inspection date. It is not legal advice or a guarantee against future service-charge demands.
Tell the surveyor about intended refurbishment, wall removal or letting before the visit. Those plans can change which visible features deserve emphasis and which additional investigations are sensible. Planning, lease and building-control permission remain separate questions for the conveyancer and authorities.
If specialist work is recommended, seek an independent investigation scope before relying on a contractor’s quotation. A quotation aimed at selling one remedy may not diagnose the cause or identify responsibility.
