Cost to Convert Leasehold to Freehold: 2026 UK Guide

Converting your leasehold to freehold means buying out your freeholder's interest in the property, so you own the building and the land outright with no lease, no ground rent and no need to ask permission for alterations. For leaseholders tired of escalating ground rent, restrictive lease covenants or the uncertainty of a shortening lease, this is one of the most valuable pieces of property law you can act on. The right exists under the Leasehold Reform Act 1967 for houses, and through collective enfranchisement for flats.

The total cost to convert leasehold to freehold for a typical house ranges from £3,000 to £15,000 or more, with the freehold premium itself the biggest variable. Flat owners going through collective enfranchisement usually pay more overall because the process is shared between several leaseholders and involves more valuation and legal complexity, often working out at £5,000 to £30,000 or more per flat depending on lease length and building value. Before you approach your freeholder, it helps to see exactly where the money goes.

Here is what typically makes up the bill:

• Freehold premium: negotiable, and by far the largest and most variable cost.
• Your solicitor fees: covers notices, negotiation and registering the new title.
• Your surveyor or valuer fees: calculates the premium and advises on negotiation.
• Freeholder's legal costs: you currently pay these too, though reform may change this.
• Land Registry fees and other disbursements: fixed charges, small compared with the premium.
• Tribunal fees: only apply if you and the freeholder cannot agree the price.

Add these together and a straightforward case on a house with a decent lease length sits toward the lower end of that range, while a flat lease under 80 years in an expensive area can push well past £15,000. Get quotes from a solicitor and a specialist valuer before you commit, because the premium itself is negotiable and the wrong opening figure can cost you thousands. Many of these charges overlap with a standard purchase, so if you want a wider view of what solicitors charge and how conveyancing disbursements are calculated, our guide to conveyancing fees breaks it down stage by stage.

The freehold premium is the price you pay your freeholder for their interest in the property, and it is calculated using a formula that surveyors apply rather than a figure the freeholder can simply invent. Understanding the three components that make up this figure lets you sanity-check any quote you are given and spot when a freeholder is asking for more than the law allows.

Ground rent capitalisation

This is the present-day value of all the ground rent your freeholder would have collected over the remaining lease term. A lease with £250 a year in ground rent and 90 years left is worth more to capitalise than one with a £10 peppercorn rent, because the freeholder is giving up a genuine income stream. Surveyors apply a discount rate, typically around 6-7%, to convert those future payments into a lump sum today.

Reversion value

This is what the freehold would be worth to the freeholder once your lease eventually expires and the property reverts to them. The longer your remaining lease term, the further away that reversion is, and the smaller its present value. A 999-year lease makes the reversion value negligible, while a 60-year lease makes it a much bigger slice of the premium.

Marriage value

Marriage value only applies when your lease has fewer than 80 years remaining, and it can add thousands to your bill. It represents the extra value created by merging the lease and freehold into one unencumbered title, and current law entitles the freeholder to 50% of that uplift.

Take a £300,000 house. With 85 years remaining, there is no marriage value to pay, so the total premium might sit around £4,000 to £6,000 once ground rent and reversion are added. Drop to 75 years remaining on the same house, and marriage value alone could add £8,000 to £12,000 on top, pushing the total premium to £15,000 or more. That single ten-year difference in lease length is often worth more than the price of a new kitchen.

The 80-year mark is the single most important number in this entire process, because it is the point at which marriage value starts applying under current law and your costs jump sharply. Leaseholders who act before their lease drops below 80 years routinely save thousands compared with those who wait, and the gap only widens the longer you leave it.

To put figures on it: extending or buying out a lease sitting at 82 years remaining might cost £5,000 to £8,000 in total. Leave the same property until the lease has fallen to 78 years, and the combination of marriage value plus a shorter remaining term can push the total cost to £15,000 to £25,000, sometimes more in higher-value areas. The premium does not rise in a straight line, it accelerates once you cross the threshold, and it keeps accelerating the shorter the lease gets.

If your lease has somewhere between 80 and 90 years left, this is the moment to start the conversation with your freeholder or begin the formal enfranchisement process, not in a year or two when you assume you will get around to it. Mortgage lenders also grow uneasy about leases under 80 years, some refusing to lend on anything below 70, which can make your home harder to sell or remortgage while you wait.

Leasehold houses

If you own a leasehold house, you have an individual statutory right to buy the freehold under the Leasehold Reform Act 1967, and you do not need permission from anyone else to start the process. You serve a formal notice on your freeholder, a surveyor values the premium, and your solicitor handles the transfer. Because only one party is involved, houses are usually quicker and cheaper to enfranchise than flats.

Leasehold flats

Flats work differently because you do not own the whole building, so you cannot buy the freehold alone. Instead, you need collective enfranchisement, where at least 50% of the qualifying leaseholders in the block agree to join together and buy the freehold as a group. This means splitting legal and valuer fees between participants, agreeing a shared negotiating position, and often appointing a nominee company to hold the freehold on everyone's behalf. It is a more involved process and typically more expensive per flat than a house purchase, because there are more parties, more valuations and more legal documents to draft.

Whichever route applies to you, the legal mechanics follow a similar shape to any property purchase: notices, valuation, negotiation and a transfer of title at the Land Registry. If you want a refresher on how conveyancing solicitors handle each of those stages, our guide to the conveyancing process covers it step by step.

The Leasehold and Freehold Reform Act 2024 received royal assent in May 2024 and promises the biggest shake-up of enfranchisement law in decades, but as of mid-2026 many of its headline provisions are still awaiting the secondary legislation needed to bring them into force. Knowing what has actually changed, rather than what has been announced, matters because it affects whether you should buy your freehold now or wait.

What is in force already: the minimum two-year ownership qualifying period before you can start enfranchisement has been scrapped, so you can act as soon as you buy a leasehold property rather than waiting two years. Non-residential limits on collective enfranchisement have also been relaxed, making it easier for flats above shops to qualify.

What is still pending: the abolition of marriage value, a change that would remove the single biggest cost driver for leases under 80 years, has not yet been implemented and requires further secondary legislation and a government consultation on the valuation rates involved. The rule shifting freeholder's legal costs away from leaseholders, so you would no longer have to pay your freeholder's solicitor and surveyor, is also still pending. Standardised lease extensions to 990 years with peppercorn ground rent are part of the wider reform package but likewise await implementation.

The practical takeaway is this: if your lease is already under 80 years, current costs reflect today's rules including marriage value, and there is no guarantee of when, or whether in the same form, the pending changes will land. Acting now avoids the risk of your lease dropping further while you wait for reform that may take years to fully commence. LEASE, the government-backed Leasehold Advisory Service, publishes free updates on which provisions have commenced and is worth checking before you make a final decision.

Buying your freehold is not a job to attempt without professional help, and the brief typically involves two different specialists working alongside each other rather than one adviser doing everything.

Your solicitor serves the formal notice on your freeholder, checks the lease and title, negotiates the legal terms of the transfer, and registers the new freehold title at the Land Registry once everything completes. This is specialist enfranchisement work, distinct from a standard house purchase, so look for a firm with genuine leasehold reform experience rather than a general conveyancer who only occasionally handles freehold purchases.

Your surveyor or valuer calculates the premium using the ground rent capitalisation, reversion value and marriage value components covered earlier, then advises you on where to pitch your opening offer and how to respond to the freeholder's counter-valuation. Get this wrong and you can easily overpay by several thousand pounds, because freeholders commonly instruct their own surveyor to argue for a higher figure.

You need both professionals because the legal and valuation sides of enfranchisement are genuinely separate disciplines. Our guide on how to choose the best conveyancing solicitor explains what questions to ask before you instruct anyone, including whether they handle leasehold enfranchisement specifically rather than standard sales and purchases.

Lease extension

Extending your lease rather than buying the freehold outright is usually cheaper and can still resolve the core problem of a shortening lease. Under the reform rules, new lease extensions run for 990 years at a peppercorn, effectively zero, ground rent, which removes the ground rent concern entirely without the cost or complexity of a full freehold purchase.

Right to manage

Right to manage, or RTM, lets qualifying leaseholders take over the day-to-day management of the building, including choosing the managing agent and controlling service charge spending, without buying the freehold at all. It is significantly cheaper than enfranchisement and does not require paying a premium, though your freeholder keeps their underlying ownership and any ground rent income continues as before.

Selling and buying freehold elsewhere

Some leaseholders decide it is simpler to sell their leasehold property and buy a freehold house elsewhere, particularly if the freeholder is being obstructive or the premium quote looks disproportionate to the property's value. This avoids the enfranchisement process entirely but means moving, with all the costs and disruption that involves.

Which option makes sense depends on your priorities. If service charge management is your main frustration, RTM solves that directly for a fraction of the cost. If ground rent and lease length are the issue but you plan to stay long-term, a lease extension may deliver most of the benefit of full ownership. Buying the freehold outright makes most sense when you want complete control over the building with no lease at all, and you are prepared to pay for it. Older leaseholders weighing up whether to fund a freehold purchase from savings or home equity sometimes look at equity release as a way to release cash without taking on new monthly repayments.

Yes, in most cases. Freehold properties typically sell for around 1% to 10% more than an equivalent leasehold property nearby, with the exact uplift depending on remaining lease length, ground rent terms and local buyer demand. A leasehold house with 999 years remaining and a peppercorn ground rent will see only a small uplift from converting, because it is already close to freehold in practical terms. A flat or house with a lease under 90 years, escalating ground rent clauses, or restrictive covenants can see a much larger jump in value once those issues are removed.

The reason is straightforward: buyers and mortgage lenders both view freehold ownership as lower risk. There is no lease to run down, no ground rent to budget for, and no freeholder consent needed for alterations or subletting. Estate agents frequently report that leasehold houses with escalating ground rent clauses are harder to sell at all, sometimes sitting on the market for months longer than freehold equivalents.

In most cases, the value uplift from converting exceeds what you paid to enfranchise, particularly if you act before your lease drops below 80 years and avoid marriage value altogether. Treat the enfranchisement cost as an investment in your property's saleability as much as a lifestyle improvement, and get an independent valuation both before and after the purchase so you can see the difference for yourself.
