Demand for deed of variation on standard leasehold extension clause

[AninF]

My friend was just about to complete the sale of her leasehold flat before Christmas when the buyer's conveyancer said that my friend needed to get a deed of variation on the standard redevelopment clause in her leasehold extension before the mortgage lender (a large and well known one) would release the mortgage funds. I have exactly the same clause in my leasehold extension.- allowing the freeholder to potentially purchase the property with compensation at the end of the original leasehold but only in certain circumstances that need to be legally proved.

I have tried to find some information about this requirement for a deed of variation online but all I can find is information that this is a standard clause under section 61 of the Leasehold Reform Housing and Urban Development Act 1993 (e.g see lease-extensions.org.uk advice) and lenders only tend to ask for a deed of variation for non standard clauses. The buyers conveyancer is not suggesting the clause is not standard but rather is saying that various lenders are now requiring a deed of variation in such standard cases.

I work in national policy and I find this very odd as it would mean that all leaseholders who have had a leasehold extension would need to pay for a deed of variation on this standard redeployment clause (at a cost of several thousand on top of the costs of their leasehold extension) before attempting to sell their flat to those who require a mortgage (and if true, this is not common knowledge and it would be impacting on housing sales across the country). If granted in all cases it would also mean that the statutory right of freeholders for redevelopment (under the Act) would become meaningless.

I also find it very odd that my friends own solicitor had not come across this change in lender policy before and that there is absolutely no online information about such a change and requirement.

The buyers conveyancer is stating that a number of lenders are asking for the deed of variation in relation to the standard redevelopment clause - but has anyone else encountered this? If you have, it would also be good to know how easy it is to obtain such deeds of variation?

After getting no response to this query (on several forums), I queried Google AI. It has stated that "The lack of widespread publicity regarding mortgage issues caused by the statutory redevelopment clause (Section 61) is primarily due to its nature as a "sleeping" legal provision that only recently collided with new 2026 market standards. The issue has remained under the radar for the following reasons:

• Standardized Industry Acceptance: For decades, this clause has been a mandatory part of every statutory lease extension under the 1993 Act. Because it includes a legal guarantee of full market value compensation, it was traditionally viewed by the industry as a "non-issue" for risk.
• Dominance of Larger Reforms: In 2025 and 2026, the public and media focus has been entirely on "headline" changes from the Leasehold and Freehold Reform Act 2024, such as the abolition of marriage value and the shift to 990-year leases. The technical nuances of break clauses in older 90-year extensions have been overshadowed by these larger "virtual freehold"
• The "990-Year" Benchmark Shift: The problem is only surfacing now because the 2024 Act established 990 years as the new "risk-free" standard. Lenders who previously accepted a 90-year extension with a break clause are now comparing those properties against 990-year leases that have no such risks, causing them to tighten their criteria unexpectedly.
• Delayed Legislation and Uncertainty: The government delayed the publication of the draft Leasehold and Commonhold Reform Bill until early 2026. This delay has left a "limbo" period where lenders are making their own conservative risk decisions in the absence of updated, clear guidance from the government or the Leasehold Advisory Service.
• Fragmented Legal Awareness: Many solicitors and brokers still treat Section 61 as a standard formality. It is only when an individual lender's automated risk model flags "redevelopment" or "break clause" as a high-risk keyword that the leaseholder discovers the problem, often at the final stage of a remortgage or sale.
• As of early 2026, campaigners and professional bodies are only just beginning to highlight how these "standard" clauses may create a two-tier market—where older extensions are seen as less "mortgageable" than the new 990-year standard."

This is an answer from an AI - so does anyone else have any evidence that the above applies. I have no idea what the AI is basing its answer on.

IF THIS IS RIGHT THEN IT COULD POTENTIALLY IMPACT ON MILLIONS OF HOUSEHOLDS and hit sales currently taking place across the country.

Thank you for coming back with that information. Not my area of expertise at all I'm afraid but regarding where AI got its information from have tried asking it a follow up question to give you links to its main sources?

[AninF]

I deliver research in my working life, so the first thing I did was check the AI sources. It didn't have a source that directly provided this material but AI can do more than simply summarise bits of text from different sources.

AI stated that it arrived at the above information through a reasoning process that involves a method called knowledge synthesis. Instead of just summarizing a single source, it combines facts, market behavior patterns, and legislative timelines to project a logical "big picture." It used

• Synthesis of Legal Facts vs. Market Impact:
  combined the established law of Section 61 (which allows landlords to reclaim property for redevelopment) with the factual introduction of 990-year leases under the Leasehold and Freehold Reform Act 2024. Reasoning follows that when a new, "higher" standard (990 years with no break clause) enters a market, older standards (90 years with a potential break clause) are logically reclassified by risk-averse lenders as "sub-optimal" or higher risk.

• Deduction of Professional Inertia:
  By looking at conveyancing and legal commentary from late 2025, it is clear that Section 61 has been a "standard" part of the 1993 Act for over 30 years. Reasoning through "industry habit" suggests that many professionals would continue to treat it as a formality until a major external shock—like the 2024 Act's implementation—forced a re-evaluation.
• Timeline Analysis:
  The 2024 Act's rollout has been phased, with major components like the abolition of marriage value and the 990-year extension becoming operational in 2025/2026. Reasoning suggests that public attention follows these "headline" benefits, naturally leaving technical risks like Section 61 in a "publicity vacuum" until they cause actual mortgage failures.
• Pattern Recognition in Finance:
  Lenders and the FCA are increasingly using automated risk models in 2026 to flag "non-standard" lease terms. By combining this trend with the legal reality of Section 61, it is a logical deduction (rather than a simple summary) that the "problem" is being discovered at the point of transaction (valuation/mortgage application) rather than through general public discourse.
• Inference of a "Two-Tier Market":
  This is an analytical conclusion drawn from the contrast between properties now eligible for a 990-year "virtual freehold" and those already extended under the old 90-year statutory rules. Reasoning suggests that if one is clearly superior in security, the other will inevitably face a "market discount" or liquidity issues, a trend observed in 2026 property market reports.

I recognise that the above is just an AI theory.

It feels, however, like there might be something in its reasoning as I cannot think why else the initial issue I raised has suddenly become visible. Statutory development clauses in leasehold extensions have been there for a long time so something new must have set of this issue.

Theory, however, is not enough - so what I am trying to find out is whether there is any visible information on others coming across similar problems i.e., have conveyancers working for lenders seen evidence that this has recently become an issue in their their case loads.
