Service Charge Impact
Leasehold properties — flats in particular — come with service charges and ground rent that can significantly eat into rental income. Unlike most costs, service charges are set by the freeholder and can increase without warning. This calculator shows how service charges and ground rent affect your net yield and net income, helping you evaluate leasehold investments more accurately.
Why this matters
A flat generating £14,000/year in rent with a £3,500 annual service charge and £500 ground rent has costs of 29% of rent before any other expenses — fundamentally different from a freehold with the same rent.
Key points
- Service charges on flats average £1,500–£5,000 per year; in London, £3,000–£10,000+ is not uncommon
- Ground rent on pre-2022 leases can be substantial — new leases after the Leasehold Reform Act 2022 are capped at a peppercorn
- Service charges are variable — a major works notice can add thousands in unexpected costs
- Leasehold Reform (Ground Rent) Act 2022 banned high ground rents on new leases but does not affect existing ones
- Buildings insurance is typically included in the service charge for leasehold flats
- Check the service charge history (3 years) before purchasing any leasehold property
Frequently asked questions
What is included in a service charge?
Service charges typically cover: buildings insurance, communal cleaning and maintenance, lift maintenance, grounds maintenance, building management fees, and a reserve fund for major works. The breakdown should be provided annually in a service charge demand.
Can service charges increase without my consent?
Yes — freeholders can increase service charges, though they must be reasonable and landlords have the right to challenge unreasonable charges through the First-tier Tribunal. Major works above £250 per leaseholder require formal consultation (Section 20 consultation).
Is ground rent still a risk for buy-to-let investors?
For properties with pre-2022 leases, doubling ground rent clauses are still a serious risk — some double every 10 or 15 years, making properties unmortgageable and difficult to sell. Always check the ground rent review clauses in any leasehold property.
Are service charges tax-deductible?
Yes — service charges and ground rent are allowable expenses deductible against rental income. This reduces the net cost but they remain a significant cash outflow.
