Many lenders restrict short leases. A valuation clarifies risk and options for remortgage or sale.
Extension premiums rise as the term shortens. Knowing the likely range avoids surprises and helps you budget accurately.
Whether you extend via the statutory route or by agreement with your freeholder, an independent valuation supports fair negotiation.
A Lease extension is when a Leaseholder pays to increase the length of time left on their property Lease. This gives them more years of ownership and can increase the property’s value. It also helps avoid higher costs in the future, as leases become more expensive to extend when they get shorter. Lease extensions are common for flats and usually require agreement with the Freeholder.

We provide clear, RICS‑compliant advice for Leaseholders and their solicitors across London, South East and the Midlands. We also provide negotiation services where we negotiate agreeable premiums with The Freehold/Leaseholders surveyor.

For Leaseholders – Leaseholders should seek an extension as your Lease approaches 80 years unexpired. It’s sensible to act early. Under the current statutory method, additional costs (such as marriage value) may apply once below this threshold. Even well above 80 years, premiums increase yearly, so early advice can save money.
For Freeholders – Freeholders require professional Lease Extension valuation advice whenever a Leaseholder seeks to extend their lease — whether through a formal statutory claim or informal negotiation. Upon receipt of a Section 42 Notice, the Freeholder must obtain an expert valuation to assess the correct premium under the Leasehold Reform, Housing and Urban Development Act 1993. Valuation advice is also essential during negotiations, Tribunal proceedings, collective enfranchisement claims, and for strategic asset management — particularly where leases fall below 80 years and marriage value becomes payable.
At Sterlingworth Surveyors, we provide clear, defensible and commercially focused valuation advice to protect freeholder interests and support effective negotiations.
