Lease Extension Guide: Everything You Need to Know
Extending your lease can feel like a maze of legal jargon and deadlines. At Ola Leslie Solicitors, we make the process transparent and manageable. This guide breaks down the legal journey, the costs involved, and why timing is everything.
1. Why Timing Matters (The 80-Year Rule)

The shorter your lease gets, the higher the price becomes. If your lease term drops below 80 years, a “Marriage Value” rule kicks in. This is a “bonus” in property value created by the extension that you must share 50/50 with your landlord. To avoid this significant extra cost, you should aim to extend before you hit the 79-year mark.
2. Statutory vs. Informal: Which Route is Right for You?

There are two main ways to extend your lease. Your fixed-fee quote will depend on the route chosen.
- The Statutory Route: Protected by the Leasehold Reform, Housing and Urban Development Act 1993. It is safer, adds 90 years to your lease, and reduces your groundrent to £0.
- The Informal Route: A direct agreement with your landlord. It can be faster but offers fewer legal protections and the landlord can withdraw at any time.
- Who Does What? (The Expert Team)
A successful extension requires two different types of experts.

- The Surveyor: Your first step. They value the property and negotiate the “premium” (the price you pay the landlord).
- The Solicitor (Ola Leslie): Once the price is agreed (or the notice is served), we handle the legal contracts, deal with the landlord’s solicitors, and register your new lease at HM Land Registry.
Note: Our role is strictly legal; we do not provide valuation or tax advice.
4. The Legal Roadmap
- Instruction & Eligibility: We confirm you have owned the property for at least two years.
- Serving Notice: We serve the formal legal notice to start the clock.
- Negotiation: A 2–6 month window for surveyors to agree on the price.
- Completion: We finalize the deed and update the Land Registry.
5. Budgeting for Your Extension
Beyond our legal fees (starting from £1000+ VAT depending on the route), you should budget for:
- The Premium: The actual price paid to the landlord.
- The Landlord’s Costs: You are usually responsible for the landlord’s reasonable legal and valuation fees.
- Disbursements: Land Registry fees and search costs.
Please note: Landlord costs are payable even if the matter does not complete.
