Lease Extension Below 80 Years: Marriage Value and Options
What to consider if a flat's remaining term is already below the 80-year threshold.
Before choosing a professional: credentials to check
Before instructing a solicitor, verify the individual and firm in the Solicitors Regulation Authority (SRA) Register. For valuations, verify any claimed RICS membership or regulated firm status through RICS. A membership badge is not proof by itself.
If you receive an informal offer, compare the proposed term, premium, ground rent and professional charges with the statutory route. An initial quote should explain what remains uncertain.
Your next step, made clearer
Avoid requesting a quote with half the facts. Prepare your lease, term and cost questions first.

What to consider if a flat's remaining term is already below the 80-year threshold.
Why the threshold matters
A statutory extension for a flat with 80 years or fewer remaining can incur marriage value under current rules. This is not a separate government charge; it reflects a share of the combined uplift in interests resulting from the longer lease.
Work out the actual remaining term
Start from the granted lease commencement date and original term, not the purchase date or a generic estate agent listing. A professional should verify the calculation and the date the statutory notice may fix for valuation purposes.
Do not assume waiting is cheaper
Planned reforms intend to remove marriage value, but the relevant valuation changes have not yet been implemented. The decision to wait needs to be balanced against sale plans, mortgage availability, lease-length erosion and uncertainty about when revised rates will apply.
Test current options
Request a formal-route premium range and consider any reasonable informal offer with independent advice. A shorter lease may affect purchaser confidence or lender terms. Check whether the landlord proposes unfavorable new rent clauses in return for a lower upfront premium.
What to ask a specialist
Ask which assumptions drive the valuation, what alternative scenarios mean for overall cost and how missed deadlines or negotiations may affect exposure. Avoid fixed compensation-style figures; lease extension premiums are property-specific.
Practical checklist
- Calculate lease term accurately
- Check any imminent transaction
- Compare current statutory premium range
- Ask about reform uncertainty
Common mistakes to avoid
A carefully documented decision is more useful than an assumption based on a search result. Check these risks before acting:
- Believing marriage value is already abolished
- Ignoring time-sensitive financing constraints
- Accepting a seemingly cheap escalating-ground-rent deal
Questions to ask a qualified specialist
- Which jurisdiction and legal procedure govern my situation, and why?
- What facts, supporting documents or valuation evidence are missing?
- What deadlines, professional fees and potential adverse costs must be planned for?
- What alternative approach should I compare before proceeding?
