Can you extend a lease after buying at auction?
Yes — you can extend a lease after buying at auction, and thanks to a significant legal change that came into force on 31 January 2025, the process is now more accessible than it has ever been. The Leasehold and Freehold Reform Act 2024 abolished the previous requirement to own a leasehold property for two years before you could start a statutory lease extension. For auction buyers, this is a genuinely important development.
Previously, if you bought a short lease flat at auction, you faced a two-year wait before you could formally claim your right to extend under the statutory route. During that period, the property could be difficult to mortgage or resell, and you had limited leverage in any negotiations with the freeholder. That restriction no longer applies.
This guide explains both routes to lease extension after auction, what the statutory process involves under the updated law, how the informal route compares, and what you need to consider when assessing a short lease lot before you bid.
What changed under the Leasehold and Freehold Reform Act 2024?
The Leasehold and Freehold Reform Act 2024 introduced several significant changes to the rights of leaseholders in England and Wales. The most immediately relevant change for auction buyers is the abolition of the two-year qualifying ownership period for statutory lease extensions.
Under the previous law — the Leasehold Reform, Housing and Urban Development Act 1993 — a leaseholder had to have owned the property for at least two years before they could serve a Section 42 notice, which is the formal legal trigger for a statutory lease extension. This rule applied even if the seller had owned the property for decades.
From 31 January 2025, that two-year requirement no longer exists. You can now initiate a statutory lease extension immediately upon completing your purchase — whether you bought at auction, on the open market, or by any other means. This removes one of the most significant practical obstacles that previously made short lease auction lots particularly difficult to manage.
It is worth noting that while the two-year rule has been abolished, other elements of the statutory process remain in place. The premium calculation, the valuation process, and the right to an independent tribunal hearing if you cannot agree terms with the freeholder all continue to apply under the updated legislation.
Do you have to be a cash buyer when buying at auction?
No. Public auction guidance is clear on this point. Auction House says you do not need to be a cash buyer, but you do need the funds available for the deposit and fees on the day, plus the remaining balance for completion shortly afterwards.
That means there are usually three broad ways people fund buying at auction:
cash
a standard mortgage
short-term specialist funding such as auction finance or bridging finance
Each option comes with different levels of speed, risk and flexibility.
The two routes to lease extension after auction
There are two ways to extend a lease: the statutory route and the informal route. Each has different protections, costs, timescales, and risks. Understanding the difference before auction day will help you assess whether a short lease lot is genuinely viable for your circumstances.
Route 1: statutory lease extension
The statutory route is the formal, legally protected process set out in the 1993 Act as amended by the 2024 reforms. It gives qualifying leaseholders the right to extend their lease by 90 years on top of the existing term, and to have the ground rent reduced to a peppercorn — effectively zero — for the duration of the extended lease.
The process begins when you serve a Section 42 notice on the freeholder. This notice sets out the premium you are proposing to pay for the extension and formally triggers the statutory timetable. The freeholder then has a set period in which to respond with a counter-notice, and negotiations proceed from there. If agreement cannot be reached, either party can apply to the First-tier Tribunal (Property Chamber) to determine the premium.
The key advantages of the statutory route are:
- You have a legal right to the extension — the freeholder cannot refuse.
- The ground rent is eliminated entirely for the extended term.
- The premium is calculated using established valuation principles, and you have the right to challenge an unfair figure at tribunal.
- The process can now be started immediately after purchase, thanks to the abolition of the two-year qualifying period under the Leasehold and Freehold Reform Act 2024.
The main drawback is time. The statutory process typically takes between six months and two years from serving notice to completion, depending on how quickly both parties reach agreement and whether tribunal proceedings become necessary.
Route 2: informal lease extension
An informal lease extension is a direct negotiation between the leaseholder and the freeholder, outside the statutory framework. There is no legal obligation on the freeholder to agree, and no prescribed formula for calculating the premium. The terms — including the length of the extension, the new ground rent, and the premium — are entirely a matter of negotiation.
The informal route can be faster than the statutory process, and in some cases cheaper, particularly where the freeholder is cooperative and the parties can agree terms quickly. However, it carries real risks:
- The freeholder may insist on a higher premium than the statutory formula would produce.
- The ground rent may continue or even increase under the new lease, rather than being reduced to a peppercorn.
- The extended term may be shorter than the 90 years you would receive under the statutory route.
- You have no right of recourse to a tribunal if the freeholder’s terms are unfair.
In practice, the informal route tends to suit buyers who need to move quickly, where the freeholder is known to be cooperative, or where the lease still has sufficient years remaining that the statutory approach would be disproportionate to the circumstances. For short lease properties where marriage value is in play, the statutory route almost always produces a fairer result.

How much does a lease extension cost?
The cost of a statutory lease extension — known as the premium — depends on several property-specific factors. There is no flat rate, and estimates can vary considerably even between two comparable flats in the same building. The main components of the calculation are:
- Ground rent capitalisation: the present value of the ground rent payments the freeholder will lose as a result of the extension.
- Reversion value: the discounted value of the freeholder’s right to recover the property at the end of the current lease.
- Marriage value: where the lease has fewer than 80 years remaining, 50% of the increase in the combined value of the property resulting from the extension must be paid to the freeholder.
As a rough indication, extending a lease with more than 80 years remaining on a mid-value flat might cost between £10,000 and £20,000 including professional fees. For a flat with 70 years or fewer, total costs can rise to £30,000 or significantly more. In addition to the premium, you will need to budget for your own solicitor’s fees, a specialist leasehold valuer, and a reasonable contribution towards the freeholder’s professional costs.
This is why confirming the lease length and obtaining a preliminary cost estimate from a leasehold valuer before you bid is so important. The lease extension cost is part of the true cost of a short lease acquisition, and it must be factored into your maximum bid — not treated as a separate problem to deal with afterwards.
What should you check before bidding on a short lease lot?
Even with the two-year rule now abolished, a lease extension after auction still requires preparation. Before bidding on any short lease lot, make sure the following has been addressed:
- Confirm the exact unexpired lease term from the legal pack or, if not stated, from the lease document itself.
- Establish whether marriage value applies by checking whether the remaining term is above or below 80 years.
- Obtain a preliminary lease extension cost estimate from a specialist leasehold valuer before auction day so you can factor this into your bid.
- Check your mortgage lender’s minimum lease requirements and whether they will lend on the current term, or require an extension to be completed before drawdown.
- Review the ground rent provisions in the lease to understand how ground rent is currently structured and what that means for the premium calculation.
- Consider whether the statutory or informal route is more appropriate for your specific circumstances, and discuss this with your solicitor before the auction.
Getting this preparation right before auction day is what separates informed buyers from those who get caught out. Our guide to what to do before you bid at auction covers the full pre-auction process, including what to look for in a leasehold legal pack.
Does the seller’s existing lease extension notice transfer to you?
In some cases, yes. If the seller has already served a Section 42 notice on the freeholder — formally triggering the statutory lease extension process — the benefit of that notice can be assigned to the buyer as part of the sale. This can be particularly valuable at auction because it means you are stepping into an already-initiated process, with the clock already ticking in your favour.
When a notice is assigned, you inherit the seller’s position in the statutory process. You are bound by the terms of the notice already served, including the proposed premium. From that point, the process continues as if you had served the notice yourself.
This is not something that will appear obviously in the auction catalogue. Your solicitor needs to specifically check for this when reviewing the legal pack, as it can significantly affect the value and attractiveness of a short lease lot. If a notice has been served and assigned, it removes the premium uplift associated with further lease depreciation and can make the extension process considerably more straightforward.
This is exactly the kind of detail that a specialist solicitor looks for when conducting an auction pack review before the auction. It is one of many reasons why legal advice before bidding is essential on any leasehold lot.
