How to Extend Your Lease in 2025: A Seller and Landlord Guide

A short lease can knock thousands off your property's value or scare off potential buyers. The good news? Extending your lease just got simpler under new 2024 legislation. Whether you're selling or letting, this guide explains how to take control and boost your property's appeal – without hiring a traditional agent.

Why Lease Length Matters

If your lease falls below 80 years, costs increase and options narrow. Mortgage lenders get twitchy, and your property's value could drop significantly. If you're thinking of selling, extending the lease first can attract more buyers and command a higher price.

New Rights Under the Leasehold and Freehold Reform Act 2024

• Leaseholders now have the right to extend immediately after purchase (no more 2-year waiting period).
• You can extend your lease by up to 990 years at zero ground rent.
• The process has been simplified; but you'll still need to plan carefully.

Two Ways to Extend Your Lease

1. Statutory Lease Extension:

• This is the formal, legal route under the Leasehold Reform Act. It offers more protection and transparency for leaseholders.
• You'll need to instruct a qualified surveyor to carry out a valuation, and a solicitor to serve a formal notice to your freeholder.
• The premium (the amount you pay to extend the lease) is calculated using a government formula. This includes factors like remaining lease length, ground rent, and property value.
• You have legal rights to challenge unfair terms via the First-tier Tribunal if negotiations stall.
• This route takes longer – typically several months – but provides certainty and is often better for leases under 80 years.
• Example: A flat with 76 years remaining might cost £8,000 - £12,000 to extend under this route, depending on the property value and ground rent.

2. Informal (Voluntary) Lease Extension:

• This means negotiating directly with your freeholder without going through the statutory process.
• It's often faster and less costly upfront, and can suit leases with more than 90 years remaining.
• However, the freeholder sets the terms - including ground rent, future increases, and extension length. Be wary of deals that include escalating ground rent or hidden charges.
• Always take independent legal advice before signing an informal agreement. If in doubt, ask a solicitor to compare terms with the statutory route.

DIY Tips for Lease Extensions

• Check Your Lease Early: Know how many years are left. Under 90? Time to act.
• Get a Valuation: A specialist surveyor can give you a realistic figure to base negotiations on.
• Use Online Tools: Lease extension calculators can help estimate costs.
• Consider Your Exit Strategy: If you're planning to sell, extending the lease first can widen your buyer pool.
• Stay Informed: Leasehold law is evolving - follow updates from GOV.UK or Leasehold Advisory Service.

Common Mistakes to Avoid

• Delaying the process: Waiting too long can push your lease below 80 years, increasing costs.
• Not budgeting properly: Lease extensions come with valuation fees, legal fees, and the premium itself.
• Agreeing informal terms without legal advice: Freeholders may include terms that cost you more in the long run.

These reforms are designed to empower leaseholders, and if you're selling or letting on your own, that's good news. With a bit of research and the right tools, extending your lease could be one of the smartest moves you make in 2025.
