Understanding the New Leasehold Reform Bill (2024–2025 Updates)
The Government’s Leasehold and Freehold Reform Bill (expected to come into force in 2025) is set to make major changes to lease extensions in England and Wales. While these reforms aim to simplify the process, they have also created uncertainty for flat owners trying to decide whether to act now or wait.
Here’s what’s expected under the new law:
990-year lease extensions instead of 90 years under the current 1993 Act
Removal of “marriage value”, which currently increases the cost of extending leases below 80 years
Simplified calculation formula, but with details yet to be confirmed by secondary legislation
More transparency and standardisation in freeholder costs and fees
What this means for you:
If your lease is already below 85 years, you may be better off extending now rather than waiting, as implementation dates and calculation methods are still being finalised.
My consultancy helps you understand both the current and upcoming rules, so you can decide what’s most cost-effective in your situation.
Lease Extension FAQs
A lease extension consultant provides independent advice to help leaseholders understand the process, options, and costs involved in extending their lease. I guide you through the steps — from checking eligibility and comparing statutory vs. voluntary routes, to planning how to approach your freeholder — without offering formal valuation or legal services.
If your lease is under 85 years, it’s often better to start the process now. Once it drops below 80 years, “marriage value” applies under the current rules, making extensions more expensive.
The upcoming reforms may remove this cost, but the implementation date is not confirmed — so there’s a financial risk in waiting. My consultancy can help you weigh both options based on your current lease term and goals.
The statutory route is protected by law under the 1993 Act — you gain an additional 90 years and pay a “premium” determined by valuation.
The voluntary route (also known as informal) is negotiated directly with your freeholder. It can be quicker and cheaper but offers less protection and may include restrictive terms.
I’ll help you understand which approach best suits your circumstances.

Yes — if you decide to proceed formally. You’ll need a valuer to calculate the premium and a solicitor to handle the legal aspects.
My consultancy helps you prepare the groundwork efficiently so that when you appoint professionals, you’re ready and informed — saving you both time and money.
