Is there a legal cap on service charges in the UK?

No. There's no legal cap on service charges in England and Wales. Nobody has set a maximum per year, per flat or per square foot, and your lease won't usually contain one either.

What the law does instead is control how the money is spent and how it's demanded. Service charges have to be reasonable, and the work or services have to be of a reasonable standard. That's a very different thing from a ceiling, and it's worth understanding before you buy, because a low charge this year tells you very little about next year's.

A service charge is your share of the actual cost of running the building. That means things like buildings insurance, repairs, cleaning communal areas, lighting, lift maintenance and a reserve fund for big jobs. Those costs go up and down with the building, not with a rule book.

A fixed cap would be awkward in practice. A new roof, a fire safety fix or a burst main can arrive in one year and cost a lot. If the law capped what could be collected, the building could simply go unmaintained. So the system lets the landlord or managing agent recover genuine costs, then gives leaseholders a way to push back when those costs aren't fair.

The flip side is that your lease sets out what you pay for and in what proportion. Read that clause carefully. If a cost isn't covered by the lease, it generally can't be charged to you at all.

Under section 19 of the Landlord and Tenant Act 1985, service charges are only recoverable to the extent they're reasonably incurred. Where work is done, it also has to be of a reasonable standard. Those are the two questions a tribunal will ask.

Reasonable doesn't mean cheapest. A landlord can choose a good contractor and doesn't have to pick the lowest quote. But the cost has to be within a range a sensible landlord might pay, and the work has to actually be done properly.

There's also a consultation rule. For bigger jobs, landlords must follow a statutory consultation process before spending over a set amount, and if they skip it, what they can recover may be limited. I haven't quoted the current thresholds here because they're set in regulations that can change, so check the latest figures with a solicitor or a leasehold advice body.

One more protection worth knowing. Landlords generally can't demand costs they only notice years later. There's a time limit for recovering costs that weren't billed promptly, and again, a solicitor can confirm how it applies to your lease.

You're not stuck with whatever lands on your doormat. Here's a sensible order to work through.

1. Ask for a summary of costs and the supporting paperwork. You have a right to request this, and it often settles things quickly.

2. Check the lease. Is the item covered, and is your share calculated the way the lease says?

3. Write to the landlord or managing agent, set out exactly what you dispute and why, and keep copies of everything.

4. Ask about the consultation. If big works were done, did you receive the required notices?

5. Apply to the First-tier Tribunal (Property Chamber) in England, or the Leasehold Valuation Tribunal in Wales, to decide whether a charge is reasonable and payable.

The tribunal is designed for ordinary people, and you don't need a lawyer to bring a case, though advice helps. Don't just withhold payment and hope. Non-payment can put you in breach of your lease, so get advice first.

You can learn a lot before you commit. Ask your solicitor to get the last few years of service charge accounts, the current budget, and details of any planned or recent major works. A sudden jump in the charge, a thin reserve fund or a big job on the horizon is a conversation starter, and sometimes a reason to renegotiate or walk away.

Ask too about any disputes or tribunal cases in the building. A block with ongoing arguments can be stressful to live in and tricky to sell.

Finally, remember that the lender and your future buyers will care about the charge as well. A high or unpredictable one can make a flat harder to sell later. It's one of those costs that sits quietly in the background until it doesn't.

Leasehold law has been under reform, and parts of the Leasehold and Freehold Reform Act 2024 are still being brought in stage by stage. Some of the changes touch on transparency around service charges and how they're demanded. Because commencement is gradual, don't assume a rule applies just because you've read about it.

Before relying on any specific threshold, deadline or right, confirm it with a leasehold solicitor. It costs far less than getting it wrong.
