A consultation deadline passed quietly on 21 October 2026, yet it could shape the price you pay to extend your lease for years to come. If you own a flat in Wimbledon, Raynes Park or anywhere in the Borough of Merton, that deadline matters more than most government paperwork ever does.
The valuation rates consultation closing this month is one piece of a much bigger puzzle. Leasehold reform October 2026 lease extension questions are now the single most common query RICS surveyors in SW19 are fielding from owners, buyers and sellers alike. The law is shifting, but slowly, unevenly, and with real financial consequences depending on timing.
This article explains exactly where things stand, what is actually in force, what is still just a proposal, and what Wimbledon leaseholders should do about it right now.
Key Takeaways
- The valuation rates consultation closed 21 October 2026, but no new rates have been set and the outcome is still unknown.
- Marriage value abolition and 990-year extensions remain uncommenced, tied up in a Court of Appeal challenge.
- The two-year ownership rule is already gone (since January 2025), and Right to Manage thresholds have already changed.
- A new Commonhold and Leasehold Reform Bill is expected autumn 2026, with Royal Assent not likely before mid-2027 and the ground rent cap targeted for late 2028 at the earliest.
- Owners with leases nearing 80 years face a genuine extend-now-or-wait dilemma that only an independent RICS valuation can properly answer.
Leasehold Reform October 2026 Lease Extension: The State of Play
Understanding leasehold reform October 2026 lease extension rules means separating three categories: law already in force, law passed but not yet commenced, and proposals that are not yet law at all.
Already in force:
- The two-year ownership requirement before claiming a lease extension was removed on 31 January 2025. You no longer need to have owned your flat for two years before starting a claim.
- The Right to Manage non-residential floorspace limit rose to 50% on 3 March 2025, making it easier for mixed-use Wimbledon blocks to qualify. Collective enfranchisement retains the 25% threshold.
- The insurance commission ban was confirmed in August 2025 but still awaits secondary legislation before it bites.
Passed but not commenced:
The Leasehold and Freehold Reform Act 2024 contains the headline reforms most owners have heard about: abolition of marriage value and a move to 990-year extensions. Neither has a commencement date. The High Court dismissed a freeholder challenge to these provisions in October 2025, but the Court of Appeal has since granted freeholder groups permission to appeal. Until that appeal resolves, commencement remains stuck.
Proposed only, not law:
A draft Commonhold and Leasehold Reform Bill sets out further ambitions: a £250 annual ground rent cap for existing English leases, a transition period originally pitched at 40 years (though a May 2026 Select Committee report recommended as short as 20 years), a ban on new-build leasehold flats in favour of commonhold, voluntary commonhold conversion by majority vote, abolition of forfeiture, and automatic Tribunal referral for service charges exceeding benchmarks by 20%.
The government intends to introduce an amended Bill in autumn 2026, with Royal Assent hoped for by mid-2027 and the ground rent cap targeted for late 2028. These are government intentions, not guarantees. Every date on this list has already slipped once.
Why the Valuation Consultation Matters So Much
The premium you pay to extend a lease or buy a freehold is calculated using deferment and capitalisation rates set by case law and Tribunal precedent. The consultation that closed on 21 October 2026 asked whether these rates should be standardised or recalculated.
If rates change, premiums change. A lower deferment rate generally means a higher premium for the leaseholder. This is not a technicality; it can shift a lease extension bill by thousands of pounds on a typical Wimbledon flat.
"Nobody can tell you today exactly what a lease extension will cost under the future regime, because the future regime does not exist yet. That is precisely why a current RICS valuation is not optional, it is essential."
The Extend-Now-or-Wait Dilemma
Owners with leases approaching 80 years face the sharpest decision. Once a lease drops below 80 years, marriage value becomes payable under current law, adding a significant extra cost that does not apply above that threshold.
| Lease Length | Current Law Position | Risk of Waiting |
|---|---|---|
| Above 90 years | No marriage value, lower urgency | Low to moderate |
| 80 to 90 years | No marriage value yet | Moderate, act before 80 years |
| Below 80 years | Marriage value applies | High, cost rises sharply |
Waiting for marriage value abolition might save money eventually, but with no commencement date and an active Court of Appeal case, there is no certainty it will happen soon. Meanwhile, every year a lease shortens, the premium under current rules typically rises. For many Wimbledon owners, locking in a known cost now under established case law is safer than gambling on reform timing.
What Wimbledon Flat Buyers Should Check
Buyers in SW19 should treat lease reform uncertainty as part of standard due diligence. Before making an offer, check:
- Lease length remaining. Anything under 85 years should prompt a conversation about extension costs before exchange.
- Ground rent terms. Doubling clauses or escalating ground rents may fall within or outside any future £250 cap depending on final drafting.
- Service charge history. Request at least three years of accounts. The government's July 2026 response confirmed standardised demands and mandatory annual reports are coming, but with no commencement date, current practice varies widely.
- Building safety status. With the Building Safety Levy now in effect since 1 October 2026 and the Remediation of Unsafe Cladding Bill introduced on 14 October 2026, ask whether the block has any cladding or remediation liabilities attached.
- Freeholder identity and responsiveness. Slow or litigious freeholders can complicate any future extension claim regardless of legislative changes.
Why a RICS Valuation Is the Only Reliable Anchor
Legislation debates aside, a formal RICS valuation gives Wimbledon owners a defensible, evidence-based premium figure under the law as it stands today. This matters for three reasons:
- It allows accurate budgeting rather than guesswork based on media headlines about reform.
- It creates a baseline figure that can be revisited if and when new rates or marriage value abolition actually commence.
- It strengthens your negotiating position with freeholders, who are themselves watching the same consultation outcomes.
Wimbledon Surveyors can produce premium calculations under current law, model likely scenarios under the proposed regime, and advise on timing strategy specific to your lease length and building.
FAQ
Will marriage value be abolished soon?
Not confirmed. The provision exists in the 2024 Act but has no commencement date, and a Court of Appeal challenge is pending.
Should I wait for the ground rent cap before extending?
The cap is only proposed, targeted for late 2028 at the earliest, and could slip further. Waiting carries real risk if your lease is approaching 80 years.
Does the two-year ownership rule still apply?
No. It was removed on 31 January 2025, so new owners can claim a lease extension immediately.
What happened with the October 2026 consultation?
It closed on 21 October 2026 after an extension, covering deferment and capitalisation rates. No outcome has been published yet.
Is leasehold being banned for all flats?
Only proposed for new-build flats under the draft Bill, with commonhold as the default. Existing leasehold flats are not affected by this specific proposal.
Conclusion
Leasehold reform October 2026 lease extension developments show a system in transition but far from transformed. Real changes have already landed, such as the removed two-year rule and wider Right to Manage access. The headline reforms, marriage value abolition and the ground rent cap, remain proposals or uncommenced law, subject to court challenges and slipping timetables.
For Wimbledon flat owners, the sensible move is not to wait indefinitely for perfect legislative clarity. Get a RICS valuation now, understand your premium under current law, and build a timing strategy around your specific lease length.
