Living in Haringey
Own a flat or maisonette in Muswell Hill, Tottenham, Crouch End, Wood Green and Hornsey? A shortening lease can affect your property’s value, mortgageability and saleability, while the premium payable can increase significantly as the lease term reduces.
Blakes Chartered Surveyors provides specialist lease extension valuation and negotiation advice for leaseholders, freeholders and solicitors across Haringey. We combine local market evidence with specialist leasehold valuation expertise, helping clients make informed decisions before notices are served, during negotiations and, where necessary, in preparation for tribunal proceedings.

Haringey contains a varied leasehold market including converted buildings, purpose-built apartments, modern developments and ex-local authority housing across the borough. Lease extension valuations can vary considerably depending on lease length, local buyer demand, ground rent provisions, service charge structures and comparable market evidence specific to different neighbourhoods within Haringey.
Our role is to provide clear, evidence-led advice on the likely premium and realistic negotiating range before you commit to a statutory or informal lease extension. We can liaise directly with your solicitor, advise on the premium figure to include within a Section 42 Notice, negotiate with the landlord’s surveyor and help you assess whether a proposed settlement is commercially sensible.
We regularly advise leaseholders, housing associations, resident management companies and private landlords throughout Haringey. Whether your priority is protecting sale value, securing mortgageability or extending before premium costs rise further, we provide practical, commercially focused advice tailored to the local property market in Haringey.
A lease extension is not just an administrative process. The valuation sets the commercial framework for the claim. If the opening figure is too high, you may weaken your negotiating position; if it is too low, you risk delay, dispute and unnecessary pressure after the landlord’s counter-notice.
Blakes prepares lease extension valuations using recognised methodology, current market evidence and practical negotiation experience. We consider the unexpired term, ground rent, lease structure, relativity, deferment and capitalization rate evidence, local flat values and the likely approach of the freeholder’s surveyor.

This may be the better route if you want one team to manage both the surveying and solicitor stages from start to finish.

For most qualifying flats, the statutory lease extension route is made under the Leasehold Reform, Housing and Urban Development Act 1993. The current statutory route provides a new lease adding 90 years to the existing term and reducing the ground rent to a peppercorn, subject to qualification and the correct procedure being followed.
The previous requirement to have owned the flat for two years has been removed for qualifying claims made from 31 January 2025. The lease and title still need to be checked carefully, and the premium should be assessed before any notice is served. Because the notice figure can influence the negotiation, we recommend obtaining specialist valuation advice at the outset.
At extension.lease we make the lease extension process simple, stress-free, and fully managed from start to finish.

A longer lease will maintain or enhance your property’s value and make it easier to sell or remortgage. Once the lease drops below 80 years the cost of extending it increases rapidly as the Tenant must pay the Landlord half of the increase in the lease’s value that results from the lease extension. This uplift is called the “marriage value”.
