Understanding Service Charges in Leasehold Apartments

Jul 15, 2026

What Is a Service Charge?

If you are buying a leasehold flat, the service charge is one of the most important numbers to get your head around. It is the amount you pay each year towards the upkeep of the building and the shared areas you and your neighbours all use. Think of it as your contribution to keeping the communal parts of the property in good order.

That money typically covers a wide range of things: cleaning and lighting of hallways and stairwells, maintenance of lifts, gardening and grounds upkeep, repairs to the roof and external walls, and buildings insurance for the whole block. It may also pay for a managing agent, a caretaker or concierge, and a sinking fund put aside for future major works.

What can surprise first-time buyers is that the service charge is not fixed forever. It can rise, sometimes sharply, and it is separate from your mortgage, council tax and utility bills. Budgeting for it properly from day one will save you a lot of stress later.

How Service Charges Are Calculated

Your share of the total cost is usually set out in the lease. Most commonly it is based on the size of your flat relative to the whole building, measured either by floor area or by the number of bedrooms. A larger flat generally pays a larger share, though this is not always the case.

The lease also sets out what the landlord or freeholder can charge for. If a cost falls outside what the lease permits, you may be able to challenge it. This is why reading the lease carefully before you commit is so valuable. Pay particular attention to:

  • The method used to apportion costs between flats.
  • Whether ground rent is separate from the service charge.
  • What the landlord is obliged to maintain, and how often.
  • Any provisions for a reserve or sinking fund.

If any of this is unclear, it is worth asking a solicitor who specialises in leasehold conveyancing to explain it in plain English before you exchange contracts.

Review the Past Accounts Before You Buy

Sellers and their agents should provide you with the last three years of service charge accounts, along with the current year's budget. Read them closely rather than skimming. They tell a story about how well the building is run.

Look for whether the actual spend each year has matched the budget. If the accounts show consistent overspends, that is a warning sign that costs may keep climbing. Check the balance of any reserve fund too. A healthy sinking fund means major works are more likely to be covered without a painful one-off bill.

It is also sensible to ask for a copy of the latest condition survey or any planned maintenance programme. A well-managed block will have clear plans for the next five to ten years. A block with no plan at all can mean the roof or lift is quietly heading towards a very expensive repair.

Ask About Major Works and Section 20 Notices

This is where service charges can really bite. Major works — a new roof, external redecorating, replacing windows or upgrading a lift — can cost tens of thousands of pounds. Your share could run into several thousand pounds, and you need to know about it before you buy, not after.

Under the law, landlords must consult leaseholders about large items of work. This is usually done through what is known as a Section 20 notice. Ask the seller and the managing agent directly:

  • Are any major works planned in the next five years?
  • Has a Section 20 consultation already started?
  • Are there any outstanding disputes or tribunal cases?
  • Is there any history of litigation with contractors?

If works have been agreed but not yet paid for, you could inherit the liability. A good solicitor will ask the managing agent for a detailed statement confirming the current position, and will usually request an LPE1 form, which summarises the leasehold information.

Watch Out for Ground Rent and Other Costs

Service charges do not exist in isolation. Ground rent is a separate annual payment to the freeholder, and it can be a fixed amount or one that doubles every ten or twenty years under some older leases. That kind of escalating ground rent can make a flat hard to mortgage or sell.

There may also be one-off charges for things like providing a management pack when you sell, or consent fees if you want to make alterations. Add these to your annual running costs so you have a realistic view of what owning the flat will actually cost you each month.

Tips for Keeping Service Charges Manageable

You cannot control everything, but you can protect yourself with a bit of diligence. Before you buy, compare the service charge for the flat you want with similar flats nearby. A charge that looks unusually low may mean the building is being under-maintained, and a large bill could be waiting.

Once you own the flat, get involved. Attend residents' meetings, read the annual accounts, and ask questions of the managing agent. If enough leaseholders take an interest, you have a real say in how the building is run and how money is spent.

Finally, consider whether the freehold could be bought collectively through the right to manage or leasehold enfranchisement. Taking more control often leads to better value and a building that is maintained properly rather than reactively. Above all, treat the service charge as a core part of your budget, not an afterthought, and you will avoid the nasty surprises that catch so many new leaseholders out.
