Over half of apartment buyers in the UK discover an issue with the lease or building management only after they’ve exchanged contracts, according to recent industry data. That means you could be legally committed to a property with a lease that’s too short, service charges that are about to spike, or fire safety problems that make it unsellable. I’ve covered property transactions for years, and the single most common regret I hear from flat buyers isn’t about the kitchen or the view — it’s about the legal and financial details they didn’t check early enough. Here’s what you actually need to know.
If you’re looking at apartments, you’re almost certainly buying a leasehold. That means you own the flat itself but not the land it sits on, and your rights are governed by a lease agreement with the freeholder. The full process of buying a UK apartment involves more legal layers than buying a house, and the stakes are higher if you miss something. A smart leak detector like the X-Sense Wi-Fi Water Leak Detector can alert you to early water damage in communal areas, but the bigger risks are in the paperwork.
What leasehold ownership actually means for you
The most important thing to understand is that you’re buying a right to live somewhere for a fixed number of years, not the building itself. That time limit is the lease, and it decreases every year. If a lease drops below 80 years, lenders typically refuse mortgages on the property — which means you’ll struggle to sell it later. I’ve seen buyers fall in love with a flat only to discover the lease has 74 years left and the seller won’t extend it. That’s not a negotiation point; it’s a dealbreaker for most people.
Ground rent on new leases is now being phased out — the Leasehold Reform (Ground Rent) Act 2022 set it at zero for most new properties. But older leases may still have ground rent clauses that increase over time, sometimes doubling every few years. That’s a cost that can catch you off guard. My advice: ask your solicitor to flag any ground rent escalation clause before you commit. If you want to understand how these costs fit into your wider budget, the guide on apartment maintenance budgeting in the UK covers the full picture.
Why service charges and fire safety can make or break your purchase
Service charges are the single biggest ongoing cost you can’t control. They cover building insurance, cleaning, repairs, and maintenance of communal areas. The problem is that these charges can increase significantly from one year to the next, and as a leaseholder you have very limited power to challenge them. According to property law specialists, you should always ask for the last three years of service charge statements to spot any unusual spikes. If the charges have jumped 20% in one year with no explanation, that’s a red flag.
Fire safety is the other major concern, especially after the Grenfell Tower tragedy. The Building Safety Act 2022 introduced new obligations for building owners, and the courts have been interpreting the law in ways that protect leaseholders. But that protection doesn’t mean you’re off the hook. For apartments in buildings over 11 metres tall, mortgage lenders may require an EWS1 form certifying fire safety. Without it, you may not get a mortgage at all. If you’re looking at a high-rise flat, ask the seller or agent upfront whether an EWS1 form exists. If it doesn’t, factor in the risk that you might not be able to sell later.
What I’d do in your position: ask the estate agent for the current service charge amount and the date of the last major works. Then ask your solicitor to check whether any major works are planned in the next two years. A £2,000 annual service charge might sound manageable until you discover the roof needs replacing and your share is £8,000. If you’re concerned about building security, a home security starter kit with outdoor cameras can give you peace of mind, but it won’t fix a poorly managed building.
Where buyers slip up — and how to avoid it
Ignoring the management company’s financial health
Many buyers never look at the management company’s accounts or meeting minutes. That’s a mistake. If the company is insolvent or has no reserve fund, you could be hit with a large one-off charge for essential repairs. Ask your solicitor to review the management company’s latest accounts and check whether there’s a sinking fund — money set aside specifically for major works. If there isn’t, budget for the possibility of a large bill in the first few years.
Overlooking lease restrictions on pets, subletting, and alterations
Lease terms can ban pets entirely, restrict subletting, or require permission for any alterations — even putting up a shelf. These restrictions might not matter now, but they could become a problem if your circumstances change. I’ve spoken to buyers who couldn’t rent out their flat because the lease prohibited subletting, leaving them stuck with an empty property. Read the lease carefully before you exchange contracts. If something seems restrictive, ask your solicitor whether it’s negotiable with the freeholder.
Assuming all lenders treat apartments the same
Some lenders won’t lend on high-rise buildings, properties above commercial premises, or ex-local authority flats. Others have stricter criteria on lease length or building materials. Check with a mortgage broker early in the process — before you make an offer — to confirm that your chosen property is likely to pass a lender’s criteria. A property lawyer specialising in leasehold transactions can also flag lender-related risks during the legal checks.
Not budgeting for service charge increases
Service charges don’t stay static. They rise with inflation, building repairs, and insurance costs. If your budget is tight at the current charge level, a 10% increase could cause real strain. Build a buffer into your monthly budget — at least 10–15% above the current service charge — so you’re not caught out. The guide to understanding service charge fine print explains exactly what to look for in the statements.

Check the lease length before you make an offer
This is the single most important step. Ask the estate agent for the current lease term and the date it started. If it’s under 90 years, you’re already in risky territory. If it’s under 80 years, most lenders won’t touch it. You can ask the seller to extend the lease before completion, but that adds cost and time — typically several months and thousands of pounds. My advice: don’t make an offer until you know the exact lease length. If you’re unsure how to interpret the lease, a real estate lawyer experienced in leasehold law can review it for you.
Review the service charge history and planned works
Ask for the last three years of service charge statements. Look for large year-on-year increases. Then ask whether any major works are planned — roof repairs, lift replacements, or cladding remediation. If major works are scheduled, ask for an estimate of your share. A £5,000 bill in your first year of ownership is not unusual for buildings with deferred maintenance. If the building has no reserve fund, that cost comes directly to you.
Verify fire safety compliance and the EWS1 form
For buildings over 11 metres tall, an EWS1 form is often required by lenders. Ask the seller or managing agent whether one exists. If it doesn’t, ask why. Some buildings are still awaiting assessment, and that can delay your purchase or make it impossible to get a mortgage. The Building Safety Act 2022 has shifted liability toward building owners, but that doesn’t mean you’re protected from delays. If you’re buying in a high-rise, make the EWS1 form a condition of your offer.
Assess the management structure and quality
Is the building managed by a professional managing agent, a resident management company, or do leaseholders collectively own the freehold? Each structure has different implications for your control over costs and decisions. If possible, speak to a current resident about their experience. Ask about responsiveness to repair requests, transparency of accounts, and any ongoing disputes. A well-managed building is easier to live in and easier to sell later. If you’re considering a flat in a building with a resident management company, the honest assessment of shared ownership covers similar decision-making trade-offs.
- 1Check the lease lengthAsk the estate agent for the current term. If under 90 years, proceed with caution. Under 80 years, discuss with your solicitor before offering.
- 2Review service charge statementsRequest three years of statements. Look for spikes and check whether a reserve fund exists. Ask about planned major works.
- 3Confirm fire safety complianceFor buildings over 11 metres, ask for the EWS1 form. Make it a condition of your offer if needed.
- 4Assess the management companyReview accounts and meeting minutes. Speak to a current resident if possible. Poor management is a long-term risk.
What’s changing in 2026 — and why it matters now
Further leasehold reforms are expected in 2026, building on the Leasehold Reform (Ground Rent) Act 2022. These are likely to make it easier for leaseholders to collectively purchase the freehold of their building and to convert leasehold properties to freehold. That’s good news for buyers, but it also means the legal landscape is shifting. If you’re buying now, ask your solicitor whether the property could benefit from future reforms — or whether any pending changes might affect the freeholder’s obligations. The courts have been interpreting the Building Safety Act in ways that protect leaseholders, as seen in recent cases like Triathlon Homes LLP v Stratford Village Development Partnership. That trend is likely to continue, but it’s not guaranteed. A specialist estate lawyer can help you understand how these developments affect your specific purchase.

Buying an apartment under strata title regulations — or leasehold, as it’s known in England and Wales — comes down to four things: lease length, service charges, fire safety, and management quality. Get those right and you’re in a strong position. Skip any of them and you could face costs or restrictions that make the flat hard to live in and harder to sell. My advice: treat the legal checks as seriously as the viewing. If this was useful, you might also want to read first flat in the UK — avoid these rookie buying mistakes.
