It is easy to get excited about a flat, work out the mortgage is affordable, and completely miss the service charge estimate buried in small print at the bottom of the listing. "£2,800 per year." That's £233 a month on top of the mortgage — and it can rise every year. That's the leasehold trap in miniature. The purchase price is just the entry fee.
Freehold means you own the property and the land it sits on outright. No time limit, no landlord above you, no annual management charges beyond what you choose to spend.
Leasehold means you're buying the right to live in the property for a fixed term — typically 99, 125, or 999 years when first granted. The freeholder retains ownership of the land and the building structure, and you pay them for the privilege of occupying it. In England and Wales, almost all flats are sold leasehold. Most houses are freehold, though leasehold houses do exist — and the Leasehold and Freehold Reform Act 2024 now bans the creation of new leasehold houses for standard residential use.
The question isn't whether leasehold is always wrong. It's whether you understand what you're signing up for before you commit.
Service charges are the ongoing payment from every leaseholder in a block to cover maintenance of shared areas — cleaning, lifts, roof repairs, external decoration, building insurance. The freeholder (or their managing agent) collects these and decides how they're spent.
The range is enormous. A well-managed ex-council block in the North of England might run to £800–£1,200 a year. A purpose-built London flat with a concierge, a gym, and a modern lift is easily £3,000–£6,000 a year. Neither figure is inherently wrong — they reflect genuinely different buildings and service levels.
The real danger isn't the baseline charge. It's the reserve fund and what happens when something big needs fixing.
Before exchanging on any leasehold property, get your solicitor to obtain the last three years' service charge accounts and the current reserve fund balance. If the fund is thin relative to the building's age and condition, treat that as a negotiating point or walk away.
Ground rent was an annual payment to the freeholder simply for the right to occupy your own flat. On older leases it ranges from £50/year at the low end to £500/year or more — with some post-2000 leases written at higher amounts that double every ten or twenty-five years. These "doubling ground rent" clauses drove the leasehold scandal of the 2010s and made some properties unmortgageable because lenders refused to lend against them.
The Leasehold Reform (Ground Rent) Act 2022, which came into force on 30 June 2022, banned ground rent on new regulated residential leases in England and Wales. Any new long lease granted after that date must set ground rent at a peppercorn — effectively zero. If you're buying a new-build flat, this protects you.
If you're buying on the second-hand market, the existing lease and its existing ground rent terms apply. You inherit whatever the original buyer signed. Before you exchange, check: the current ground rent amount, whether it escalates, and the mechanism. Fixed ground rent is manageable. RPI-linked is predictable. Any clause that doubles on a set schedule is worth flagging with your solicitor and potentially your mortgage lender — who may have the same concern independently.
Leasehold conveyancing costs more than freehold. Your solicitor has to read and report on the full lease (often 40–100 pages of dense legal text), check the service charge accounts, verify ground rent terms, review any resident management company structure, and flag covenants restricting alterations or subletting. That process takes meaningfully longer than a standard freehold transaction.
As a result, expect to pay roughly £300–£600 more in legal fees on a leasehold purchase than on a comparable freehold, before searches and Land Registry fees. It's not a huge figure on its own, but it adds to a cost profile that's already higher than the asking price suggests.

Every leasehold counts down. A 125-year lease granted in 1990 has 89 years left. A 99-year lease from 2000 has 73 years left. As leases shorten, properties become harder to sell — most mortgage lenders want at least 70–80 years remaining at the end of the mortgage term — and the cost of extending the lease rises.
The critical threshold is 80 years. Above 80 years, extending the lease costs a premium based on the lost ground rent and the value of the reversion (the right to take back the property when the lease expires, discounted to today). Below 80 years, you also pay "marriage value" — 50% of the uplift in property value that the extension creates. This can add tens of thousands of pounds to the cost.
To estimate what an extension would cost on your specific property, use our Lease Extension Calculator. As a benchmark: a £300,000 flat with 75 years remaining and a ground rent of £250/year would cost approximately £13,000–£14,000 in premium alone, plus a further £2,000–£4,000 in combined legal and valuation fees for both sides. That's £15,000–£18,000 total — before you've done any work on the flat.
The Leasehold and Freehold Reform Act 2024 includes a provision to abolish marriage value entirely, which would significantly reduce the cost of extending short leases. But as of August 2026, the secondary legislation to bring this specific provision into force has not been laid. Until it is, the 80-year rule still applies in full.
Say you're choosing between two properties on the same street. A leasehold flat at £280,000 (78-year lease, £200/year ground rent, £2,000/year service charge) versus a freehold house at £295,000. On paper, you save £15,000 by buying the flat. Here's what that saving looks like in practice.
| Cost item | Leasehold flat | Freehold house |
|---|---|---|
| Purchase price | £280,000 | £295,000 |
| Extra conveyancing (leasehold) | +£450 | — |
| Ground rent × 10 years | +£2,000 | £0 |
| Service charges × 10 years (rising ~5%/yr) | +£25,155 | £0 |
| Lease extension premium (78 yrs → extend now, before 80-yr trap) | +£11,500 est. | — |
| Lease extension legal and valuation fees | +£3,000 | — |
| 10-year total extra cost vs freehold | +£42,105 | — |
The £15,000 headline saving becomes an extra £27,105 of spending over ten years. And this ignores any section 20 major works demands, which can arrive without warning and add thousands more.
I'm not saying leasehold is always the wrong choice. In many cities — and London especially — the only affordable foothold on the property ladder is a leasehold flat. Ownership with these costs can still beat renting over a long enough horizon. Use our Buy vs Rent Calculator to model that for your specific numbers. But please don't think the £15,000 gap between the flat and the house is a saving. You've just deferred the spending.
There are situations where leasehold is fine:
The problem is that most flat buyers don't know to check these things — or they check too late, after they've fallen in love with the property. Your solicitor should flag the serious issues, but you'll make better decisions if you ask the right questions before you even start the mortgage process.
The Act received Royal Assent on 24 May 2024 and is being implemented in stages. Here's what matters in 2026:
The reforms are the biggest change to leasehold law since the 1993 Act. But they're coming in slowly, and the parts leaseholders are most excited about aren't live yet. Don't make a buying decision on the basis of protections that aren't yet enforceable.
No. But if you don't, you'll find it very hard to sell once the lease drops below about 80 years. Most lenders need at least 70–80 years at the end of the mortgage term, so on a 25-year repayment that typically means needing 95+ years at purchase. Below that threshold, the buyer pool shrinks fast.
Not at all — you still pay to maintain the property. The difference is that you control when and how the money is spent, rather than a management company billing you on their schedule at their chosen contractor rates.
If at least half the qualifying flats in a block agree, you can buy the freehold collectively — this is called collective enfranchisement. The 2024 Act made the qualifying criteria easier to meet. Individual flat owners can't buy the whole building's freehold alone the way a leasehold house owner can.
Usually yes, because freehold gives cost certainty that leasehold can't match. The ongoing service charges, potential major works demands, and eventual lease extension costs add up meaningfully over time. That said, a leasehold with a long remaining term (100+ years), low fixed ground rent, and well-managed block with clean accounts is a rational purchase — provided you understand the total picture going in.
