Everything you need to extend your lease

At Extension.Lease, we provide specialist lease extension valuations in the London Borough of Havering together with expert advice on freehold purchase and collective enfranchisement across the borough, including Romford, Hornchurch, Upminster, Harold Wood, Harold Hill, Rainham and Elm Park. We act for leaseholders across a wide range of property types, from 1930s and 1950s houses in Elm Park and Hornchurch, to purpose-built post-war blocks in Harold Hill, town centre apartments in Romford, and ex-local authority estates where many leases were originally granted during the 1980s Right to Buy era.
Havering is in the middle of one of the larger council-led regeneration programmes in outer London. In 2018 the council chose Wates Residential as its joint venture partner to rebuild a series of its own sites, starting with the Waterloo and Queen Street area of Romford, where around 1,380 new homes are planned. Smaller schemes at New Green in Rainham and Park Rise in Hornchurch are finished, and the Farnham and Hilldene area of Harold Hill is earmarked for a later phase. If your block is on or near one of these sites, take advice before you serve a notice.
A situation we see often in Havering is a maisonette or small block flat let on a 99 year lease in the 1970s, which now has well under 50 years left. Buyers in Hornchurch and Upminster are frequently families with large mortgages, and most lenders want comfortably more than 80 years remaining. A short lease can stall a sale or knock a sizeable sum off the price. Extending before you put the property on the market, or at least serving notice so the claim can pass to your buyer, keeps your options open.
We handle lease extensions for flats in Axis Court, Market Place Apartments, and Maxwell Road Court, as well as ex-local authority stock on the Waterloo Estate and Hillrise Estate.
In Hornchurch, we work on apartments in Oakwood Court, Laburnum Court, and ex-local authority blocks within the Airfield Estate and Avelon Road Estate.
Upminster lease extensions include flats in Russell Court, St Lawrence Court, and ex-local authority stock near Cranham Village Estate. Many properties here are in low-rise, purpose-built blocks.
Our Rainham work covers ex-local authority developments such as the Ferry Lane Estate and Briarleas Estate, alongside private flats in schemes like Riverside Court.
In Harold Hill, we act on lease extensions for flats in the Hilldene Estate and Chippenham Road Estate, plus smaller private developments like Chudleigh Court.
Collier Row lease extensions include ex-local authority flats on the Collier Row Estate, and private leasehold apartments in Peverel House and Eastwood Court.

The premium on any Havering flat rests on three figures: what your flat is worth with a long lease, how many years are left and how much ground rent you pay. Values vary a good deal across Havering. A two bedroom flat in Upminster or Emerson Park will usually be worth noticeably more than a similar one in Harold Hill or Rainham, and the premium follows the value.
You will also pay your landlord’s reasonable valuation and legal costs, which the 1993 Act allows them to recover, together with the Land Registry fee. Our own fee is fixed at £2,750 + VAT*, which covers the valuation, the negotiation and all of the legal work, and it is paid in two equal instalments.
Send us your lease details and we will give you a free estimate of what your Havering extension is likely to cost in total.
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.
Havering Council kept its housing rather than transferring it to a housing association. If you bought a Right to Buy flat in Romford, Harold Hill, Rainham or Collier Row, or bought from someone who did, the council is very likely still your freeholder. Day to day management was run for some years by an arm’s length company, Homes in Havering, but that work returned to the council in 2012. Your Section 42 notice is therefore served on the London Borough of Havering itself.
Outside the council estates, most leasehold flats in the borough are in private hands. Purpose-built blocks from the 1960s to the 1980s in Hornchurch and Upminster are often owned by investment freeholders or by residents’ management companies, and the newer apartment schemes around Romford town centre usually belong to a developer or a ground rent investor. Havering also has a great many maisonettes, where the freeholder may be a small private landlord or even the owner of the flat above or below. We confirm the registered freeholder at HM Land Registry before anything is served.
Everything you need to extend your lease






In most cases, yes. Unlike many London boroughs, Havering did not transfer its housing to a housing association. Management was handled for a period by Homes in Havering, an arm’s length company, but that came back in house in 2012 and the council has remained the freeholder throughout.
We always check the freehold title at HM Land Registry before serving a notice, because a Section 42 notice served on the wrong party is not valid.
Possibly not straight away. The council’s joint venture with Wates Residential covers sites such as Waterloo and Queen Street in Romford and Farnham and Hilldene in Harold Hill, and several other sites have been paused or are under review. If the council later needs to buy your flat, compensation is based on its market value, and the length of your lease feeds into that value.
Talk to us first. We will look at where your block sits in the programme and set out the figures either way.
A 125 year lease granted in 1988 has about 87 years left today and will fall below 80 years in the early 2030s. Once that happens, marriage value is added to the premium, and it can be a significant sum.
The valuation date is fixed on the day the Section 42 notice is served. Serving while you still have more than 80 years left keeps marriage value out of the calculation, even if the negotiation runs on after the lease passes that mark.
Because the premium is a share of the value the freeholder gives up, it rises and falls with what your flat is worth. With identical leases, a flat worth £450,000 in Upminster will produce a noticeably larger premium than one worth £280,000 in Harold Hill.
That is why we value each flat on evidence from its own street, block or estate rather than using a borough-wide figure. Using the wrong comparables is one of the easiest ways to overpay.
This is common in Hornchurch, Elm Park and Collier Row. Your statutory right to a lease extension is the same whoever the freeholder is, so you can serve a Section 42 notice on a private individual just as you would on a company or the council.
Many neighbours prefer to agree terms informally first, and that can work well. We can value the extension, advise on a fair figure and, if talks stall, move to the formal route so your rights are protected.
Yes. Under the 1993 Act the leaseholder pays the landlord’s reasonable costs of the valuation and the legal work involved in granting the new lease. The council will usually instruct its own valuer and lawyers, and their reasonable fees are added to your bill.
We check that the figures claimed are reasonable and query anything that looks excessive. Costs incurred by the landlord in a tribunal hearing are not normally recoverable from you in the same way.
Yes. Once the Section 42 notice has been served, the benefit of it can be assigned to your buyer on completion. Your buyer takes over the claim and keeps the valuation date your notice has already fixed.
This is a useful route for short lease flats, because many lenders will not lend on a lease with fewer than 80 or 85 years left. Your buyer’s solicitor will want to see the notice and any counter-notice, which Arcadia Law can provide.
Not any more. The rule that a leaseholder had to own the flat for two years before using the statutory route was abolished on 31 January 2025 by the Leasehold and Freehold Reform Act 2024.
That means you can start the process as soon as you complete your purchase, which helps if you have just bought a flat with a shortening lease and want to fix the valuation date before the term drops further.
