If you own or are considering a flat in one of Golders Green’s mansion blocks, purpose-built developments or converted houses, leasehold reform deserves attention. The remaining term, service charge history, ground rent and building management can influence value, mortgageability and the practical experience of ownership.
At Ellis & Co Golders Green, buyers, sellers and existing owners regularly ask what has changed, what is still proposed and whether they should act now. The answer is not the same for every property. The key is to distinguish law that is operational from reforms that still need implementation.
This guide sets out the position as at September 2026. It is general information, not legal advice. Anyone making a decision about a lease extension, collective enfranchisement, commonhold conversion or transaction should consult a qualified solicitor and, where a premium is involved, a specialist valuer.
What has already changed under the 2024 Act?
The two-year ownership rule has gone
The Leasehold and Freehold Reform Act 2024 became law in May 2024, with provisions taking effect in stages. On 31 January 2025, the two-year ownership requirement for statutory lease extension and enfranchisement claims was removed. An eligible buyer no longer has to wait two years after acquisition before beginning a statutory claim.
This can make a short lease more manageable in a transaction because the buyer has the ability to consider action from the start of ownership. It does not remove the premium or professional costs, and it does not guarantee that every flat or building qualifies. The current notice procedure and deadlines still need careful handling.
Ground rent: where the peppercorn rule comes from
The peppercorn restriction for most new regulated long residential leases comes from the Leasehold Reform (Ground Rent) Act 2022, not the 2024 Act. It generally applies to qualifying leases granted from 30 June 2022, with later commencement for retirement properties and limited exceptions.
An owner who bought an older existing lease after that date may still have to pay the ground rent written into the lease. For an NW11 purchase, ask the conveyancer to check the amount, review clause and lender acceptability. A statutory flat lease extension under the present system reduces the ground rent to a peppercorn.
What is still to come?
A proposed 990-year statutory extension
The 2024 Act contains provisions to increase the standard statutory extension for flats from 90 years to 990 years. Those provisions were not yet operational in September 2026. Under the current route, a qualifying flat owner can add 90 years and reduce ground rent to a peppercorn after paying the premium.
The future 990-year term would greatly reduce the need for repeat extensions, but owners should not prepare a transaction on the assumption that it is already available. Check the current commencement position immediately before serving a notice or agreeing a sale strategy.
Marriage value and the future valuation framework
The 2024 Act provides for marriage value to be removed and for government to prescribe valuation rates. Implementation depends on further legal steps. In July 2026 the government consulted on those rates and on the process costs associated with enfranchisement.
Under the current system, GOV.UK warns that extension costs rise significantly at 80 years or less. Owners near that threshold face a genuine timing decision. Waiting may expose the lease to further decline, while proceeding now uses the known framework. A specialist valuation is essential before assuming either route is cheaper.
Commonhold and restrictions on new leasehold flats
A draft Commonhold and Leasehold Reform Bill was published in January 2026 and scrutinised by a House of Commons committee. It proposes a modernised commonhold system, a pathway for conversion and restrictions on new leasehold flats. The final Bill was still awaited in September 2026, so the proposals were not yet law in their final form.
Commonhold gives the owner an indefinite interest in the flat and a membership interest in the body responsible for common parts. Existing mansion blocks would not simply change tenure overnight. Conversion would involve legal, financial and collective decisions, and the rules may change as the Bill progresses.
What the July 2026 leaseholder announcement actually means
In July 2026 the government confirmed its policy response on service charge transparency and legal-cost protections. It also opened work on enfranchisement valuation rates and process costs. The announcement did not mean that every measure took immediate effect that month.
Government material indicated that leaseholders would start to see some service charge and legal-cost changes during 2027, after statutory instruments and implementation work. Owners should therefore check the live law rather than relying on the date of a press release.
The NW11 market context for flat owners
Lease decisions should be grounded in the property as well as the law. Official UK House Price Index data showed that the average price across the London Borough of Barnet was about £604,000 in June 2026, 2.9% lower than a year earlier. This borough figure covers many neighbourhoods and property types; it is not a valuation for a Golders Green flat.
Ellis & Co’s 2026 Golders Green market insight page reports an average achieved price of about £687,000 for flats and apartments over the latest 12-month period shown. Again, mansion block, road, floor, condition, lease length and service charge profile can create substantial differences. Use comparable evidence for the same type of flat wherever possible.
In a market where buyers have choices, a well-documented leasehold position can support confidence. Unanswered questions about major works, escalating ground rent or a very short term can reduce the buyer pool or lengthen conveyancing. Addressing the records early can be as important as presentation and asking price.
What NW11 sellers should prepare before marketing
Confirm the lease term and title information
Do not wait for an offer to locate the lease. Confirm the date, original term and calculated unexpired term. Ask your solicitor to check whether any deed of variation, licence or supplemental document must also be supplied.
Assemble the management pack evidence
Mansion block buyers will want to understand service charges, reserve funds, insurance, planned works and any disputes. Contact the managing agent or freeholder early about the standard sales pack and typical lead time. Delays in obtaining this information can hold up a chain.
Decide how to address a shorter lease
Possible options include extending before marketing, starting the statutory process, marketing with a clear price adjustment, or proceeding without an extension where the market and funding allow. Since the two-year rule has been removed, assigning a seller’s notice is no longer the only way to prevent a new two-year wait, but transaction-specific legal advice remains important.
Keep claims precise
Avoid promising that reform will make an extension cheaper or that a future law will complete before the sale. Marketing should state the verified term and current position. Buyers can then take advice based on facts rather than speculation.
What buyers of Golders Green flats need to check
- The exact unexpired lease term and whether the title and lease plans match the flat, storage and parking being sold.
- Current ground rent, review provisions and compatibility with the intended lender’s criteria.
- At least several years of service charge accounts, the current budget and any reserve fund balance.
- Planned works, Section 20 consultations and recent major expenditure on roofs, lifts, windows or communal systems.
- Building insurance, fire-safety information and any matters raised by the lender or surveyor.
- Restrictions on subletting, pets, hard flooring, alterations and short-term occupation.
- The identity and performance of the freeholder, managing agent, right-to-manage company or residents’ company.
- Any arrears, tribunal proceedings, disputes or breaches that must be resolved before completion.
Why service charge trends matter
A single annual figure can be misleading. Compare several years and ask why costs changed. A rise may reflect necessary investment, insurance or utilities, while an unusually low charge may indicate that maintenance has been deferred. The building survey and management information should be read together.
Why the lender should be involved early
Lenders apply their own policies to lease term and ground rent. The same flat may be acceptable to one lender but not another. If the lease is unusual or close to a threshold, provide details to the broker and lender early so the mortgage route does not unravel late in the transaction.
Should an owner extend now or wait?
There is no universal answer. Relevant factors include the current term, proximity to 80 years, intended sale date, premium estimate, ground rent, mortgage plans and confidence in the implementation timetable. Owners with comfortable terms may have more flexibility; owners close to a critical lending or valuation threshold may have less.
Ask for two scenarios: the likely position under current law and the risks of waiting. The purpose is not to predict Parliament but to understand what can be controlled today. Professional advice can also identify whether an informal offer from the freeholder is genuinely competitive with the statutory route.
Collective options in mansion blocks
Some Golders Green blocks already have resident-led management, right-to-manage arrangements or share-of-freehold structures. These expressions are not interchangeable. Share of freehold usually means owning an interest in the freehold entity while still holding a lease; right to manage transfers management functions without buying the freehold.
If residents are considering collective enfranchisement or eventual commonhold conversion, participation, governance and funding deserve as much attention as the acquisition price. Professional advice should cover the building’s qualifying status and the continuing obligations after control changes.
Understanding a mansion block management pack
Mansion blocks often have more complex shared systems than a small conversion. Lifts, central heating, porterage, gardens, roofs, fire precautions and communal decorations can all affect the annual budget. The management pack should be read as a history of the building and a guide to commitments that may arise after completion.
Planned works and Section 20 consultation
Where qualifying major works are proposed, leaseholders may receive consultation notices under Section 20 of the Landlord and Tenant Act 1985. Ask for every current notice, estimate and related minute. The absence of a final demand does not mean that a project carries no future cost.
Look for repeated references to the same defect in meeting minutes or correspondence. A roof leak, ageing lift or external repair programme may move through investigation, specification and tender stages over several years. A surveyor can consider the physical condition while the solicitor checks the contractual route for recovering costs.
Reserve funds and balancing charges
A reserve or sinking fund can reduce the impact of major expenditure, but the lease determines whether one can be collected and how it may be used. Confirm the balance, recent withdrawals and planned purpose. Also ask whether historic accounts have produced balancing charges or credits after year end.
Disputes, arrears and tribunal decisions
A dispute involving the freeholder, manager or residents may affect costs and lender appetite. Ask whether the block has active tribunal proceedings, unpaid service charges or disagreements over works. The seller should resolve personal arrears, while the buyer needs advice on any issue that continues with the building.
Preparing an NW11 flat for a smoother sale
Start by calculating the unexpired term from the lease, not from memory or an old listing. Order official title documents and locate licences, guarantees and planning or building-regulation approvals for alterations. Where the management pack is known to take time, request it before a buyer is found if your solicitor recommends doing so.
Give the agent accurate information about the ground rent and service charge period. If the latest amount is an estimate, say so. If a major-work proposal exists, provide the available documentation and obtain legal advice about how it should be handled in the contract. Early transparency helps prevent a surprise after the buyer has committed money to a survey and mortgage application.
If the lease term is likely to concern buyers, take valuation and legal advice before setting the asking price. A clear strategy is more credible than a vague promise that reform will solve the issue. The chosen approach should be achievable within the intended sale timetable.
Questions Golders Green owners often ask
Is an informal lease extension quicker?
It can be negotiated without following the full statutory process, but the offered term, premium, ground rent and new clauses require careful comparison. A superficially low premium may be offset by less favourable terms. Ask advisers to compare the whole package.
Can a buyer obtain a mortgage on a short lease?
Possibly, but lender criteria vary and the choice may narrow as the term reduces. The years remaining at the end of the mortgage and the ground rent terms may be relevant. Refer the exact lease details to the broker and lender early.
Does a 990-year extension apply now?
No. The 2024 Act provides for that future term, but in September 2026 the operational statutory flat extension remained 90 years. Check current law again at the point of action because implementation is continuing.
Will the July 2026 announcement reduce my bill immediately?
Not by itself. It confirmed policy and the route towards later measures. A press announcement is not a substitute for commencement regulations or a property-specific calculation.
What should I budget beyond the premium?
A lease extension can involve the owner’s solicitor and valuer, the statutory premium and, under the current regime, recoverable reasonable professional costs on the landlord’s side. Tribunal or dispute work can add further expense. Ask advisers for a written scope and cost assumptions, and retain a contingency rather than budgeting only for the headline premium.
Can the estate agent give legal advice?
The agent can provide marketing information, local comparable evidence and practical transaction support. Interpretation of the lease, qualification for statutory rights and the drafting or service of notices belong with a qualified legal adviser. Keeping those roles clear reduces the risk of acting on an informal summary or overlooking a material restriction.
