Ground Rent and Service Charges for Leasehold Buy-to-Let
Leasehold flats are the backbone of many BTL portfolios — but ground rent and service charges can erode yield fast. Here's how to evaluate, challenge and budget for them.

Introduction
Leasehold flats often look like easy buy-to-let — manageable, secure, central. But ground rent and service charges can swing the maths from healthy yield to negative cash flow within a year. With ongoing leasehold reform and the abolition of new ground rents, 2026 is a good moment to refresh your approach. Here's what to look at before buying and how to manage costs after.
Ground rent: the new regime
The Leasehold Reform (Ground Rent) Act 2022 effectively banned ground rent on most new residential long leases granted after 30 June 2022 — capped at one peppercorn (zero). The Leasehold and Freehold Reform Act 2024 goes further and is expected to cap existing ground rents at a low fixed sum once the relevant provisions commence.
Existing leases and doubling clauses
Pre-2022 leases may still carry significant ground rent, sometimes with clauses doubling every 10 or 25 years. These are now generally regarded as unfair and mortgageable lenders may refuse. Always have your solicitor check the doubling pattern before exchange.
What service charges should cover
Reasonable costs of repairing, insuring and managing the building, plus a contribution to a sinking fund for long-term works. Insurance commissions, management fees and 'admin' uplifts are increasingly challenged at tribunal.
Section 20 consultation
Where the cost of any single set of works exceeds £250 per leaseholder, or a long-term agreement exceeds £100 per year, the landlord must run a statutory Section 20 consultation. Failing to consult caps recoverable cost at the relevant threshold per flat — a powerful protection for leaseholders.
Challenging a service charge
Apply to the First-tier Tribunal (Property Chamber) — no fee to issue, low cost throughout. The tribunal can determine reasonableness of past or proposed charges, and the decision binds the landlord and all leaseholders.
Underbudgeting is the killer
Many BTL investors model the year-one service charge and forget inflation. Building insurance has risen 30–60% since 2022, and major works on flats over 11m are subject to fire safety remediation. Always build in 5–10% annual increases and a contingency for cladding-related costs.
Lease extension and enfranchisement
Once a lease drops below 80 years, the cost to extend rises sharply due to marriage value. The 2024 Act removes marriage value once enacted and extends statutory lease extensions to 990 years. Plan extensions well in advance if your lease is approaching that threshold.
