Everything you need to extend your lease

Extension.Lease provides specialist lease extension valuation advice across the London Borough of Waltham Forest, together with strategic guidance on freehold purchase and collective enfranchisement matters. We act for leaseholders throughout Walthamstow, Leyton, Leytonstone, Chingford, Highams Park and Upper Walthamstow, advising on properties ranging from Victorian terrace conversions and Warner flats to post-war purpose-built blocks and substantial former council estates where many leases were originally granted during the 1980s Right to Buy period.
A considerable proportion of Waltham Forest’s leasehold housing stock was constructed between the 1950s and 1970s, with 99- and 125-year leases frequently issued in the 1980s following Right to Buy disposals. We regularly advise on properties within estates such as the Priory Court Estate and Priory Park area in Walthamstow; the Boundary Road Estate; the Markhouse Road and South Grove estates; the Oliver Close and Shernhall Street blocks; the Cathall Estate and Beaumont Road Estate in Leyton; the Oliver Road and Francis Road vicinity blocks; the Harrow Green Estate in Leytonstone; the Lakehouse Estate; the Avenue Road Estate; the Chingford Mount and Friday Hill estates; the Larkswood Estate; the Hale End Estate in Highams Park; and the Leyton Grange Estate. Many of these predominantly low- to mid-rise purpose-built local authority developments are now approaching, or have passed, the critical 80-year unexpired lease threshold at which marriage value becomes payable under the Leasehold Reform, Housing and Urban Development Act 1993.
Lease extension valuation in Waltham Forest requires a clear understanding of sub-market distinctions – from the strong demand for Warner maisonettes and Victorian conversions in Walthamstow Village and Leyton, to regeneration-influenced values around Blackhorse Road and Lea Bridge, and more suburban pricing in Chingford and Highams Park. Our valuation approach incorporates detailed assessment of unexpired lease term, ground rent provisions, relativity evidence, deferment rates and marriage value to ensure statutory premiums are calculated accurately, strategically and defensibly.
We prepare detailed Section 42 valuation reports, advise on premium negotiation strategy and provide tribunal-ready expert evidence where required, acting against private freeholders, housing associations and the London Borough of Waltham Forest. Each instruction is supported by carefully analysed and up-to-date comparable evidence drawn from across the borough’s varied residential micro-markets, ensuring premiums are robust, commercially realistic and fully reflective of prevailing local conditions.
We handle lease extensions for flats in period conversions along Grosvenor Park Road and Hoe Street, as well as ex-local authority stock in the Lloyd Park Estate and Higham Hill Estate. Modern private schemes like Central Station Apartments are also common instructions.
In Chingford, we act on lease extensions for riverside apartments in King’s Head Hill Court, low-rise private blocks such as Chingford Mount Court, and ex-local authority flats on the Chingford Hall Estate.
Leyton lease extensions include flats in Victorian conversions along Francis Road and Colworth Road, modern apartments in Leyton Central, and ex-local authority stock on the Oliver Close Estate.
Our Leytonstone work covers flats in Raymond Court, Grove Court, and period conversions along Gwynne Road, as well as ex-local authority developments in the Cathall Estate.
In Highams Park, we handle lease extensions for private apartments in Avon Court and The Charter Apartments, alongside ex-local authority blocks on the Larkswood Estate.

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.
