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 Newham, including Stratford, West Ham, East Ham, Forest Gate, Plaistow, Canning Town, Custom House, Beckton, Manor Park and North Woolwich. Newham’s residential landscape ranges from Victorian terraces and converted houses in Forest Gate and Manor Park to docklands developments in Royal Victoria and established purpose-built estates across Plaistow and East Ham. Our valuations are grounded in detailed local knowledge and supported by carefully analysed comparable evidence drawn from across the borough.
We regularly advise leaseholders within former local authority estates where many flats were sold under the 1980s Right to Buy programme and are now approaching key lease length thresholds. Our experience includes estates such as the Carpenters Estate in Stratford, the Keir Hardie Estate in Canning Town, the Forest Gate Estate, the Woodgrange and Claremont areas, the Priory Park Estate in Canning Town, the Plashet Estate in East Ham, the Boleyn Estate area, the Custom House Estate, the Freemasons Estate in East Ham, and the Winsor Park and Tollgate Road estates in Beckton. These predominantly 1960s–1980s purpose-built developments require a valuation approach that reflects their tenure mix, block configuration and local sub-market characteristics.
If you are pursuing a statutory lease extension under the Leasehold Reform, Housing and Urban Development Act 1993 (Section 42 Notice), precise premium calculation is essential – particularly where leases are nearing or below 80 years unexpired and marriage value becomes payable. We prepare detailed, RICS-compliant and tribunal-ready valuations, advise on relativity and marriage value, and negotiate with Newham Council, housing associations and private freeholders on your behalf. Our coordinated approach ensures the statutory process is managed efficiently, strategically and with your financial interests fully protected.
We handle lease extensions for apartments in Stratford Halo, Unex Tower, and One Stratford, as well as ex-local authority stock in the Carpenters Estate and Stratford Village Estate.
In Canning Town, we act on flats in Hallsville Quarter, Rathbone Market Apartments, and Vermillion Tower, alongside ex-local authority blocks in the Keir Hardie Estate and Freemasons Road Estate.
Royal Docks lease extensions include waterfront developments like Royal Wharf, Western Gateway Apartments, and Capital East Apartments, plus ex-local authority stock in the Custom House Estate.
Our Plaistow work covers ex-local authority estates such as the Plaistow North Estate and Plaistow South Estate, as well as private flats in St Andrew’s Court and Eastview Apartments.
East Ham lease extensions include flats in ex-local authority developments such as the Brady Estate and Burges Estate, plus smaller private blocks along High Street North and Barking Road.
In Forest Gate, we work on lease extensions for Victorian conversions along Romford Road and Woodgrange Road, and ex-local authority blocks in the Forest Gate 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.
