Barnet Lease Extension Solicitors & Surveyors

Everything you need to extend your lease

Valuation, notices and a new lease for Barnet flats, from Golders Green mansion blocks to Colindale

Barnet Council

 

Extension.Lease delivers specialist lease extension valuation advice throughout the London Borough of Barnet, alongside expert guidance on freehold acquisition and collective enfranchisement. We act across High Barnet, Finchley, Hendon, Golders Green, Mill Hill, Colindale, Edgware, Totteridge, Whetstone and Friern Barnet, advising leaseholders in everything from Edwardian mansion flats and converted period properties to large-scale purpose-built developments and former council estates where many leases were first granted during the 1980s Right to Buy programme.

 

Barnet has several of London’s larger estate regeneration schemes. Grahame Park in Colindale is being rebuilt in stages, with Notting Hill Genesis delivering the early phases and the council bringing forward plans for the north-eastern part. West Hendon is being redeveloped by Barratt Metropolitan, and Dollis Valley in Chipping Barnet by Countryside with L&Q, while Brent Cross Town is creating a new district beside the North Circular. Leaseholders in older blocks within these schemes should check the redevelopment timetable before serving a notice.

 

In Golders Green, Hendon and Finchley, many flats sit in mansion blocks or 1930s purpose-built blocks where the residents have already bought the freehold through a company. If that applies to you, an extension can often be agreed within the building at modest cost. Where the freehold is held by an investor, and especially where there is a head lessee between you and the freeholder, the statutory route is usually the more reliable way to secure 90 extra years and remove the ground rent.

From First Call to New Lease in Barnet

Most Barnet extensions are completed within six to twelve months of the notice being served. These are the three stages.
Stage 1: Inspection and Advice
Your flat is inspected by a Blakes surveyor, or valued from the desk where appropriate, and we gather sales evidence from the same block or nearby. In a mansion block, sales of flats with long leases in the same building are often the best evidence of all. We then advise on the figure to propose and what you should expect to pay in the end.
Stage 2: Making the Formal Claim
Your Section 42 notice is served by Arcadia Law on Barnet Council or your private landlord, and on any intermediate landlord where the block has one. A counter-notice is due by the date stated in the notice, at least two months after service. Our surveyor negotiates the premium, and any terms left unresolved can be referred to the First-tier Tribunal.
Stage 3: New Lease Granted
Once everything is agreed, Arcadia Law complete the new lease and register it at HM Land Registry. A further 90 years are added to your current term, and ground rent falls to a peppercorn, which in practice is nil. Your lender is told, and the title register is updated to show the longer lease and its new terms.

How the Statutory Lease Extension Process Works

The Price of a Barnet Lease Extension

Flat values in Barnet range from the top end of the outer London market around Golders Green and Hampstead Garden Suburb to far more modest levels in Burnt Oak and Colindale. Because the premium is a share of value, where your flat sits in the borough has a direct effect on the figure, alongside the lease length and the ground rent.

  • Mansion blocks in Golders Green and Hendon: Many leases in these blocks were granted for 99 years and some are now well below 80. Marriage value is then payable, and with higher flat values it can be a substantial sum.
  • Council flats managed by Barnet Homes: Right to Buy leases are generally 125 years at around £10 a year. Ground rent has little effect, but 1980s leases are now near the 80 year point.
  • Modern blocks in Colindale: Newer leases are usually long, but some include ground rents that rise over time, which a statutory extension removes.

The 1993 Act also lets your landlord recover its reasonable valuation and legal costs from you, and there is a Land Registry fee to pay. Our fee is fixed at £2,750 + VAT*, which includes the valuation, the negotiation and all legal work, payable 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.

Barnet Freeholders at a Glance

Barnet Council owns its housing stock, which is managed on its behalf by Barnet Homes, part of The Barnet Group. Rather than bring the service in house, the council has kept this arrangement and approved a new ten year management agreement running from 2026. For a Right to Buy flat on a Barnet council estate, the freeholder is the London Borough of Barnet, even if every letter you receive carries the Barnet Homes name, and the Section 42 notice goes to the council as landlord.

Away from the council estates, most leasehold flats have private freeholders. Golders Green, Hendon and Finchley have many mansion blocks and 1930s purpose-built flats owned by property companies or resident-owned management companies, while Edwardian houses in Finchley and Mill Hill have often been divided into flats with a private freeholder. On regeneration estates such as West Hendon and Dollis Valley, new homes are owned by the developer partners and housing associations, so the landlord can be different from the one on an older lease nearby.

Choosing Us for Your Barnet Flat

  • Mansion block experience: Blocks with head leases, management companies and more than one layer of landlord are a feature of parts of Barnet, and we know how to serve and negotiate where several landlords are involved.
  • Evidence from the right postcode: We value from comparable sales close to your flat, not borough averages, so a Golders Green flat is not priced off Burnt Oak.
  • Valuers and lawyers together: Blakes handle valuation and negotiation, and Arcadia Law the notices and the new lease.
  • One fixed fee: £2,750 + VAT for the full statutory process, with nothing charged by the hour.
