Calculation notes
- This is an early budgeting estimate for leasehold enfranchisement, not a formal valuation or legal quote.
- Actual premiums can depend on lease terms, deferment and capitalisation evidence, relativity evidence, development value, intermediate interests, negotiation, tribunal outcome, lender requirements, and legal eligibility.
- Leasehold and Freehold Reform Act 2024 changes are being commenced in stages and valuation-rate details may require secondary legislation. Use the reform scenario as a comparison until your adviser confirms the applicable rules.
- For a live transaction, instruct a specialist leasehold valuer and conveyancer.
Leasehold planning
How the freehold purchase range is framed
The range is there to help decide whether a specialist valuation is worth pursuing, not to replace one.
Premium estimate
The calculator estimates possible freehold purchase cost from leasehold value, ground rent, years remaining, legal and valuation costs, and broad relativity or premium assumptions.
It is intended to frame the scale of the decision before professional valuation, not to replace a statutory enfranchisement valuation.
Freehold-cost pathleasehold value, rent and term assumptions -> estimated premium range + legal/valuation costs -> total cost estimate
Order-of-magnitude check
Example: checking the order of magnitude
- Leasehold property value: entered by user
- Ground rent: entered by user
- Years remaining: entered by user
Result: The output gives a planning range rather than a precise legal valuation.
The range helps decide whether to seek a specialist enfranchisement valuation.
What needs professional advice
- Marriage value, lease clauses, deferment rates and valuation evidence can change the result.
- Use this as a prompt for leasehold advice rather than a final negotiation figure.
