Secured Loan on a Flat

Minimum Floor Area and Property Value Requirements

Many secured loan lenders apply a minimum floor area for flats, most commonly 30 square metres but in some cases higher at 40 or even 50 square metres. This restriction is designed to exclude very small studio apartments and micro-flats, which lenders consider harder to sell and more susceptible to value volatility. If your flat is a compact studio in a city centre, it is worth checking the floor area against potential lenders' criteria before applying.

Minimum property value requirements are also commonly applied. Some lenders will not consider properties with a market value below £50,000 or even £75,000, and in areas with lower property values this can limit options further. These thresholds can change with market conditions, so checking current lender criteria through a broker is always advisable.

Purpose-built flats — those designed and built as flats from the outset — are generally preferred by lenders over converted flats, which are former houses or commercial buildings that have been converted into flats. Converted flats can raise concerns about soundproofing, structural integrity, the adequacy of the conversion works and planning compliance. Lenders will assess converted flats more carefully and may impose lower LTV caps.

Leasehold Considerations for Flat Owners

The vast majority of flats in England and Wales are leasehold, meaning the flat owner holds a long-term lease from the freeholder rather than owning the land and building outright. Leasehold flats are perfectly acceptable security for most secured loan lenders, but the specific terms of the lease are critical. Lease length, ground rent provisions and service charge terms all affect lender appetite.

Most lenders require a minimum of 70 years remaining on the lease at the end of the loan term. Ground rents above 0.1% of the property value per year are problematic with many lenders following the changes introduced by the Leasehold Reform (Ground Rent) Act 2022. Service charge arrears registered against the title can prevent lending until cleared.

For newer flats sold under leases created after June 2022, ground rent is capped at a peppercorn by law, which removes one of the main historical concerns about leasehold flats. However, legacy leases with escalating ground rents remain a challenge until they are either varied or the property is sold to a new owner who benefits from the new regulations.

Freehold flats — relatively uncommon in England and Wales — can pose different challenges for lenders, as the maintenance and repair obligations for the building need to be managed by private agreement rather than through a standard lease. Lenders assess these case by case.

High-Rise Flats and EWS1 Cladding Issues

The fire safety issues that emerged following the Grenfell Tower fire in 2017 have had a lasting impact on the market for flats in buildings with external cladding. The EWS1 (External Wall System) assessment process was introduced to provide assurance to lenders and buyers about the fire safety of the external walls of a building. An EWS1 certificate is typically required by lenders for buildings over 11 metres tall where there is external cladding of any kind.

Certificates are graded A1 (safe, no remediation required), A2 (safe, minor works may be advisable), B1 (remediation advisable but not required before sale) and B2 (remediation required before sale or mortgage). Lenders will generally proceed for A and B1 rated buildings, but B2 buildings — where significant remediation is needed — are effectively unmortgageable until the works are completed.

The Building Safety Act 2022 provided important protections for qualifying leaseholders, ensuring that the cost of cladding remediation cannot be passed to leaseholders in most circumstances. This has helped unlock some previously stalled cases, though the remediation process for some buildings is still ongoing. If your building has a B2 rating, it is worth establishing what remediation programme is in place and when it is expected to be completed.

Above-Commercial and Mixed-Use Buildings

Flats situated directly above commercial premises — particularly restaurants, takeaways, dry cleaners or other businesses involving cooking, chemicals or high footfall — face additional restrictions from many secured loan lenders. The concerns relate to noise, smell, pest risk, insurance complexity and the potential difficulty of selling the property in the future. Most high-street lenders will not accept these properties, while specialist lenders will consider them at reduced LTVs, typically capped at 65-70%.

The specific type of commercial premises below the flat is relevant — a flat above a quiet professional services office is treated more favourably than one above a busy fast-food restaurant. Lenders often make these decisions on a case-by-case basis following a detailed valuation report that comments on the commercial use and its impact on the flat.

Mixed-use buildings that are part commercial and part residential — such as Victorian terraces converted to have a shop at ground floor and flats above — are relatively common in urban areas and are considered by a reasonable number of secured loan lenders, subject to the nature of the commercial use and an acceptable valuation report. A broker who handles urban properties regularly will know which lenders are currently comfortable with mixed-use buildings in your area.
