Kensington & Chelsea Lease Extension Solicitors & Surveyors

Everything you need to extend your lease

Lease extensions for flats in Chelsea, Kensington and Notting Hill, valued by surveyors who know the estates

Kensington and Chelsea Council

 

At Extension.Lease, we provide specialist lease extension valuations in Kensington & Chelsea together with expert advice on freehold purchase and collective enfranchisement across the Royal Borough, including Kensington, Chelsea, South Kensington, Earl’s Court, West Brompton and North Kensington. We act for leaseholders across a diverse range of property types, from prestigious red-brick mansion blocks in Kensington and Chelsea, to white stucco conversions in South Kensington, portered purpose-built blocks in Earl’s Court, modern riverside apartments at Chelsea Harbour and Imperial Wharf, and ex-local authority estates where many leases were granted during the 1980s Right to Buy era. This includes properties on estates and developments such as Lancaster West Estate, Silchester Estate, Trellick Tower, Edenham Way, Henry Dickens Court, Worlds End Estate, Cremorne Estate, Warwick Road Estate, Elm Park Gardens (RBKC-owned blocks), Campden Estate, Sutton Estate (Chelsea), Dalgarno Gardens, Hazlewood Tower, and the Notting Barns area surrounding Ladbroke Grove.

 

The Royal Borough has some of the most valuable flats in the country, and that changes the arithmetic of a lease extension. When a flat is worth well over a million pounds, marriage value on a lease below 80 years can be a large figure, and each year of delay tends to add to it. Small points in the valuation, such as the condition of the flat, the floor it is on or a share in a garden square, can move the premium noticeably. That is why evidence from the same street or building matters so much here.

 

Stucco terraces in Notting Hill, Earl’s Court and South Kensington were turned into flats in large numbers, and many conversions were sold on 99 year leases. Some now have well under 80 years left. In these buildings the freeholder may be an investor, a company owned by the flat owners or the owner of another flat in the house. A lease extension is often the simplest fix, but where most owners want to act together, buying the freehold can be worth considering. We can advise on both and price each route.

From Valuation to New Lease in Kensington and Chelsea

Six to twelve months is typical for a lease extension in the Royal Borough, measured from the first valuation to registration. These are the three stages.
Stage 1: Assessing the Flat and the Lease
Blakes Chartered Surveyors inspect your flat and compare it with recent sales nearby, often in the same terrace, mansion block or estate. Arcadia Law check the freehold and any head lease so we know who must grant the new lease. You then receive our advice on the opening premium and the figure you should expect to agree.
Stage 2: Formal Notice and Negotiation
Arcadia Law serve the Section 42 notice on your landlord, which may be the Royal Borough, an estate such as Cadogan, a housing association or a private freeholder. The landlord must give a counter-notice by the date in the notice, at least two months after service. We then negotiate the premium, with the First-tier Tribunal available if agreement cannot be reached.
Stage 3: Completion and Registration
Once everything is agreed, Arcadia Law complete the new lease and register it at HM Land Registry. You gain 90 years on top of the term you already hold, and the ground rent is reduced to a peppercorn, so nothing is payable. Your flat becomes easier to mortgage and sell, and its value reflects the longer lease.

How the Statutory Lease Extension Process Works

The Cost of Extending a Lease in Kensington and Chelsea

Your premium is driven by the value of your flat, the years remaining on your lease and the ground rent. In this borough the value is usually the dominant factor, so the same unexpired term can cost very different amounts in Chelsea and in North Kensington.

  • Estate flats and stucco conversions: Many leases in Chelsea, South Kensington and Notting Hill were granted for 99 years or less and are now below 80 years, where marriage value applies. At these values it can form a large part of the premium.
  • Council leases: Right to Buy flats on Royal Borough estates were usually sold on 125 year leases at a ground rent of around £10 a year. Leases from the 1980s are now nearing 80 years, so timing matters.
  • Housing association blocks: Leases vary by landlord and age, and we check the ground rent and repair terms before advising on a figure.

The 1993 Act lets your landlord recover its reasonable valuation and legal costs, and there are Land Registry fees on top. Our fee is fixed at £2,750 + VAT*, which covers the valuation, the negotiation and all of the legal work, in two equal instalments.

Lease Extension Calculator

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.

Who Holds the Freehold in Kensington and Chelsea?

Much of Chelsea belongs to the Cadogan estate, which covers about 93 acres around Sloane Street, Cadogan Square and the King’s Road. In South Kensington the former Smith’s Charity estate has been owned by the Wellcome Trust since 1995, and smaller private estates hold pockets of Kensington and Holland Park. Flats on these estates are often let on leases granted out of a head lease, with a building owner sitting between you and the estate, so a lease extension starts with working out which landlord can grant the new lease.

The council is a large freeholder too. After the Grenfell Tower fire the Royal Borough took housing management back from the Kensington and Chelsea Tenant Management Organisation on 1 March 2018, so leaseholders on estates such as Lancaster West in North Kensington and World’s End in Chelsea now deal with the council directly. Housing associations own many older blocks, including Clarion’s Sutton Estate in Chelsea, and the converted terraces of Notting Hill and Earl’s Court are mostly owned by private freeholders.
