Everything you need to extend your lease
Richmond upon Thames is one of London’s most expensive boroughs, and its lease extension market behaves accordingly. Values sit closer to prime central London than to the rest of outer south-west London, and transactions here are noticeably more cash-driven. That changes the calculation as a lease approaches 80 years: where a buyer does not depend on a lender’s view of the unexpired term, a short lease can still trade. The premium rises all the same, and marriage value below 80 years is expensive on a high-value flat.
The river shapes values across the borough. A flat with views over the Thames in Richmond, Twickenham or Barnes can be worth far more than a similar sized flat a mile inland in Whitton or Hampton Hill, and the premium for a lease extension follows that value. Period conversions on Richmond Hill, mansion blocks in Barnes and Kew, and 1930s purpose-built blocks in Teddington all have their own sales patterns. We value each flat on evidence from its own building or street, because that is what holds up in a negotiation.
One of the borough’s biggest housing projects is at Ham Close, where RHP, Hill Group and Richmond Council are replacing the existing blocks with a scheme of 452 homes. The first new block reached its highest point in November 2025, and the council has made a compulsory purchase order to support the scheme. Leaseholders on estates earmarked for redevelopment need advice before spending money on a lease extension, because the length of the lease can affect what they are offered when their home is bought.
We work on lease extensions for flats in riverside mansion blocks such as The Gateways, Heron Court, and Old Deer Park Gardens, as well as modern apartments in Kew Riverside and Richmond Bridge Estate. Ex-local authority stock includes parts of the Queens Road Estate and Pagoda Avenue area.
In Kew, we handle flats in developments like Kew Riverside Apartments and Emerald Square, plus period conversions on Kew Green. Ex-local authority schemes include High Park Estate and North Road Estate.
Our Twickenham work includes purpose-built flats in Twickenham House, Regency Court, and Twickenham Riverside, alongside ex-local authority estates like Heathfield Estate and Glebe Way Estate.
We carry out valuations for leaseholders in private blocks such as Thames Point, Bishops Court, and Church Road Court, as well as ex-local authority developments on Stanley Road Estate.
In Hampton, we handle smaller private developments like Hampton Court House Apartments and flats in converted period houses near Hampton Hill High Street, along with ex-local authority stock in Priory Road Estate.
Barnes lease extensions often involve period mansion blocks such as Riverview Gardens, Elm Bank Mansions, and riverside conversions along The Terrace. Leasehold flats here are premium assets, requiring precise valuation due to scarcity of comparables.

Speak to a surveyor about your Richmond lease extension or freehold purchase, or arrange a free initial consultation at our Raynes Park office, a short drive away.
The figure you pay depends on what your flat is worth, how long is left on the lease and the ground rent. In a borough with values as high as Richmond’s, the gap between a lease of 82 years and one of 78 can be significant, because marriage value starts below 80 years.
You also pay your landlord’s reasonable valuation and legal costs, which the 1993 Act allows them to recover, plus Land Registry fees. Our own fee is fixed at £2,750 + VAT*, covering the valuation, the negotiation and all of the legal work, and paid in two equal instalments.

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.
Our free, instant Lease Extension Calculator gives you an instant estimate of the premium payable under the Leasehold Reform, Housing and Urban Development Act 1993. It’s a quick, useful guide for leaseholders wanting to understand the likely cost of extending their lease before taking formal advice.
Richmond Council no longer owns council housing. In July 2000 it transferred all of its homes to Richmond Housing Partnership, now known as RHP, which today owns and manages more than 11,000 homes for social rent and shared ownership. If you own a former council flat in Ham, Hampton, Whitton, Mortlake or elsewhere in the borough, your freeholder is very likely RHP rather than the council, and that is where your Section 42 notice must be served.
Outside RHP’s estates there is a wide spread of private freeholds. Richmond Hill and Twickenham have Victorian villas converted into flats, Barnes and Kew have red brick mansion blocks and Edwardian conversions, and Teddington and Hampton have purpose-built blocks from the 1930s onward, plus newer riverside developments. Freeholders range from investment companies to residents’ management companies and the owner of the flat next door. We confirm who owns your freehold from the title before any notice is served.

In almost every case it is RHP. Richmond Council transferred all of its homes to Richmond Housing Partnership in July 2000, and the freeholds of blocks containing Right to Buy flats went with them. If you bought your flat from the council before then, your lease passed to RHP as landlord.
We always check the freehold title at HM Land Registry before a notice is served, because a Section 42 notice served on the wrong party is not valid.
Talk to us before you do anything. Ham Close is being redeveloped by RHP and Hill Group with the council, and the council has made a compulsory purchase order to support the scheme. If your flat is being acquired, the length of your lease can affect the compensation, but paying a premium may not make financial sense.
We can look at your position in the scheme and work through the numbers with you before any notice is served.
Quite urgent, if the lease is close to or below 80 years. Many conversions on and around Richmond Hill were sold on 99 year leases, and once the term drops below 80 years marriage value becomes payable. In an area with high values that can add a significant sum.
The valuation date is fixed when the Section 42 notice is served, so serving promptly protects you against the lease shortening further during negotiations.
Because the premium is a share of the flat’s value. With identical leases, a flat worth £750,000 in Barnes will produce a much larger premium than one worth £350,000 in Whitton.
Richmond has sharp differences in value between the riverside, the town centres and the western parts of the borough. We value every flat from sales in its own street, block or estate, and we avoid relying on borough averages that would overstate or understate your figure.
Yes. Under the 1993 Act every landlord, including RHP, can recover its reasonable valuation and legal costs from the leaseholder. These are limited to what is reasonable for the work involved, and they are not payable for any tribunal proceedings.
We include an allowance for your landlord’s costs in our estimate so you can see the full picture before you start, and we query any costs that look out of line.
Often, yes. Where enough flat owners take part, the 1993 Act gives a collective right to buy the freehold. Once you own it, you can grant yourselves longer leases by agreement, usually for a nominal premium.
It involves more coordination than a single lease extension, and everyone has to agree how the building will be run afterwards. Blakes can value the freehold and Arcadia Law can handle the purchase and the new leases.
A statutory extension replaces the ground rent with a peppercorn, so the rising ground rent clause no longer applies under the new lease. That can make the flat easier to mortgage and sell, because some lenders are wary of ground rents that increase sharply.
The rising ground rent does affect the premium, because the landlord gives up that income. We value it carefully, since the assumptions used can change the final figure.
Yes. Once the Section 42 notice has been served, the benefit of it can be assigned to your buyer on completion of the sale. The buyer then takes over the claim with the valuation date already fixed.
This can help where a buyer’s lender is cautious about the remaining term. Arcadia Law can arrange the assignment as part of your sale, so the extension continues without starting again.
