London Property Values and Available Equity
High average property values in London translate directly into large amounts of available equity. A homeowner with a property worth £600,000 and an outstanding mortgage of £300,000 has £300,000 in equity, and most secured lenders will advance up to 80–85% combined loan-to-value (LTV). In this example that could mean up to £210,000 available to borrow as a secured loan — a figure far beyond what an unsecured personal loan could offer.
Higher incomes in London also support larger loan amounts. Because secured lenders assess affordability against your income and outgoings, the higher-than-average salaries in the capital mean borrowers often qualify for larger advances. This makes secured loans particularly popular in London for major home improvement projects, funding business investments, or consolidating multiple high-rate debts into a single lower monthly payment.
Property values in London have historically been resilient, which means lenders are generally comfortable with London security. Prime central and outer Zone 2 to 4 properties tend to attract the most competitive rates. Zone 5 and 6 locations may fall into lenders' standard residential criteria but are usually straightforward.
Property Types: Victorian Terraces, Mansion Flats and High-Rise Apartments
London has an exceptionally diverse property stock, and the type of property you own affects which secured lenders will consider your application and at what rate. Victorian terraces — common across Hackney, Islington, Lambeth, and similar inner-London boroughs — are generally well-received by lenders and carry no particular restrictions provided the property is in standard construction and good structural condition.
Mansion flats and purpose-built Edwardian conversions are common in areas such as Kensington, Maida Vale, and Hampstead. These are usually accepted by lenders, though leasehold tenure means the broker will check lease length and service charge arrangements. A lease below 80 years can cause complications and may restrict the pool of willing lenders, potentially increasing the rate offered.
New-build high-rise apartments — particularly those built or clad between 2000 and 2020 — face the most scrutiny. Lenders assess cladding type and fire safety remediation status. Buildings with an EWS1 form confirming safety compliance are generally accepted. Where an EWS1 has not been completed or shows a Category B2 or C2 result indicating remediation needed, the number of willing lenders narrows significantly. Some specialist lenders will still consider these properties, but rates will be higher to reflect the additional security risk.
Period conversions and ex-local authority flats — widespread across many London boroughs — sit in the middle ground. Ex-local authority flats with a high proportion of social tenants in the block may face restrictions from certain lenders. Always disclose the tenure, block type, and any known cladding issues to your broker upfront to avoid wasted applications.
