Everything you need to extend your lease

At Extension.Lease, we provide specialist lease extension valuations and freehold purchase advice across the London Borough of Bromley. From purpose-built flats in Beckenham and established developments in Bromley town centre to period conversions in Chislehurst and Shortlands – as well as ex-local authority estates in Orpington, Penge, Mottingham and Anerley – our valuations are grounded in genuine local insight and supported by carefully analysed comparable evidence. We have extensive experience advising on estates where many leases were originally granted during the 1980s Right to Buy era, including the Cray Valley Estate and Ramsden Estate in Orpington, the Mottingham Estate and Sidcup Road blocks, the Anerley and Penge estates around Maple Road, Thicket Road and Croydon Road, the Cotmandene Crescent Estate in St Paul’s Cray, the Tubbenden Lane and Pinewood areas of Orpington, the Widmore Green and Plaistow estates in Bromley, the Burnt Ash Lane blocks, and former council developments around Southborough Lane, Rangefield Road and Downham Way. Many of these 1960s–1980s purpose-built estates now have leases approaching critical term thresholds.
We regularly advise leaseholders in Bromley, Beckenham, Orpington, Chislehurst, Petts Wood, West Wickham, Penge, Anerley, Shortlands, Hayes and Mottingham. The borough’s market ranges from commuter-focused apartment schemes near Bromley South and Beckenham Junction to suburban estate-based housing and low-rise blocks built during the 1970s and 1980s. As leases approach or fall below 80 years unexpired, marriage value becomes payable under the Leasehold Reform, Housing and Urban Development Act 1993, often resulting in a marked increase in the premium – particularly for former Right to Buy flats. Early, specialist valuation advice can therefore make a substantial financial difference.
Bromley Council remains a significant freeholder of former local authority flats across the borough, and we have extensive experience negotiating statutory lease extensions in this context. Blakes Chartered Surveyors prepare detailed, RICS-compliant valuations based on Bromley-specific market data and relativity analysis, while Arcadia Law serve the Section 42 notice, negotiate the premium and complete registration at HM Land Registry. Our integrated approach ensures the statutory process is managed efficiently, strategically and with your financial interests fully protected.

In Beckenham, we act on flats in developments such as Kelsey Lodge, Park Langley Court, and Fairfields Court, plus ex-local authority stock in Cator Estate and blocks along Kings Hall Road.

Extending your lease is one of the most important steps you can take to protect your property’s value and mortgageability. If your lease is under 100 years or has a high ground rent, its value may already be affected. Once it falls below 80 years, the cost of extending increases significantly due to marriage value.

Everything you need to extend your lease






A statutory lease extension is a legal right that allows leaseholders to extend their lease by 90 years and remove any ground rent. This right is granted under the Leasehold Reform Housing and Urban Development Act 1993, and it applies to almost all leaseholders in the UK, whether your property is owned by a local authority or a private landlord.
The entire lease extension process typically takes between 6 to 12 months. This includes the valuation, notice serving, negotiations with the freeholder, and legal work to register the new lease. However, the exact time can vary depending on factors like the complexity of negotiations or if any issues arise with the property documents.
The premium is the price you pay to extend your lease. It depends on several factors:
Our surveyors will carry out a valuation to calculate a fair premium for your lease extension and negotiate where required to ensure you do not overpay.
If your lease has less than 80 years left, the cost of your lease extension will usually be higher. This is because properties with shorter leases are considered less valuable, and the cost to extend is affected by something called the marriage value, which is the increase in the property's value once the lease is extended. To avoid higher costs, it’s often best to act before your lease drops below 80 years.
Yes, your freeholder may charge fees for their involvement in the lease extension process. These fees typically cover the cost of legal work, including the drafting and registration of the new lease. While these fees are usually similar to the costs you incur, they can sometimes be higher depending on the freeholder's approach.
