Buying a Flat in Central London: The Checks That Matter

Most homes in central London are flats, and most of those flats are leasehold. This means the legal and financial details behind a property are just as important as the property itself. O’Sullivan Property Consultants has advised buyers, landlords and owners across central London since 2005, and our experience in property management gives us a practical understanding of how buildings and leases work in reality. Below are the key checks we recommend before making an offer.

Understand the Lease

When you buy a leasehold flat, you own the right to occupy it for a set number of years rather than the building itself. The remaining lease length affects the property’s value, the availability of mortgage finance and how easy it will be to sell in future, so it is essential to establish exactly how many years remain. Where a lease is becoming shorter, your solicitor can advise on the process and likely cost of an extension. Understanding this at the outset avoids complications later in the purchase.

Review the Running Costs

Service charges cover the upkeep of the building, including cleaning, insurance, lifts, porterage and repairs, and they vary considerably between properties. Request recent service charge accounts, ask whether any major works are planned and establish whether a reserve fund is in place. You should also confirm whether ground rent is payable and how it is calculated. A flat that appears attractively priced can look quite different once the annual costs are considered, so it is important to assess the full cost of ownership. Our stamp duty calculator can help you plan your overall budget.

Consider the Practical Details

Every building has its own rules. These may include restrictions on pets, short lets or alterations to the property. If you are buying to let, confirm that the lease permits this and whether the freeholder’s consent is required. Beyond the paperwork, consider outside space, storage, noise levels, natural light and parking. These points are easy to overlook on a short viewing, so we are happy to arrange further visits to help you make your decision.

Align the Purchase with Your Plans

Your own circumstances should guide your search. If you intend to live in the property long term, consider whether it will continue to suit you as your needs change. If you are buying as an investment, consider what tenants in the area are looking for and whether the running costs support a sensible return. Because we offer lettings and property management alongside sales, we can discuss how a property might perform as a rental and what is involved in letting it. Many of our clients use more than one of our services.

Appoint the Right Professionals

Instruct a solicitor with leasehold experience at an early stage to review the lease and legal documents, and consider a survey, particularly for the period buildings common across Mayfair, Marylebone and Knightsbridge. Alongside your advisers, our team can support you with local market knowledge, comparisons with similar properties nearby, guidance on running costs and the arrangement of viewings. As members of Propertymark and The Property Ombudsman scheme, we are committed to clear and transparent advice.
