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 Croydon. From landmark developments in Croydon town centre such as Saffron Square, Altitude 25 and Ten Degrees, to 1930s mansion blocks in Purley, purpose-built blocks in Sanderstead and period conversions in South Croydon, our advice is rooted in genuine local expertise and supported by robust comparable evidence. We also act for leaseholders in ex-local authority and former Right to Buy estates including the Waddon Estate, New Addington estates, Forestdale developments, the Regina Road area, and the Shrublands Estate, as well as blocks around London Road, Thornton Heath and Selhurst where many leases were originally granted in the 1980s.
As your lease term reduces, you will usually have the right to extend it by 90 years and reduce your ground rent to nil under the Leasehold Reform, Housing and Urban Development Act 1993. While Croydon Council may offer informal lease extensions, these proposals can include less favourable terms, shorter extensions or revised ground rent provisions, and the premium payable is not independently determined under the statutory framework. It is essential to obtain valuation advice to ensure the premium is fair and that you are not compromising long-term value.
We manage the entire statutory lease extension process on your behalf, providing a clear, structured and fully coordinated service from initial valuation through to completion and registration of the new lease. Blakes Chartered Surveyors prepare detailed RICS-compliant valuations and negotiate the premium using strong Croydon market evidence, while Arcadia Law handle the Section 42 notice, negotiations and registration at HM Land Registry. We act for flat owners across East Croydon, West Croydon, South Croydon, Purley, Sanderstead, Thornton Heath, Selhurst, Waddon and New Addington – including Croydon Council properties – and if your lease is approaching or below 90 years, early advice can make a significant difference to cost.
We handle lease extensions for prominent developments such as Saffron Square, Altitude 25, and Green Dragon House, along with ex-local authority stock in the Taberner House Estate and Whitgift Estate.
In East Croydon, we work on flats in Bridge House, Vista Apartments, and Morello Quarter, plus ex-local authority developments on Addiscombe Court Estate. The area’s fast rail connections make it popular with commuters.
South Croydon lease extensions include 1930s mansion blocks such as Beechwood Court and Cedar Court, alongside ex-local authority stock in Selsdon Road Estate.
Our Purley work covers flats in Woodcote Valley Court, Reigate Court, and ex-local authority schemes along Brighton Road. Many flats here are in low-rise purpose-built blocks with communal gardens.
In Thornton Heath, we act on lease extensions for flats in Brigstock Court, St Paul’s Court, and ex-local authority blocks in the Bensham Lane Estate and Thornton Heath 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.
