Compare the total cost of leasehold vs freehold ownership over 10 years, including lease extension and enfranchisement options.
This calculator provides estimates only. Lease extension and enfranchisement costs depend on individual lease terms and professional valuations. Property value estimates are approximate. Consult a qualified surveyor and solicitor for accurate costs.
The distinction between leasehold and freehold ownership is one of the most important concepts in UK property law, and it has significant financial implications for property owners. A freeholder owns both the property and the land it sits on indefinitely, while a leaseholder owns the right to occupy the property for a fixed period (the lease term) and must pay ground rent to the freeholder. Most flats in England and Wales are leasehold, while most houses are freehold, though there are exceptions. This calculator helps you compare the true cost of leasehold ownership against freehold ownership over a 10-year period. It factors in ground rent, service charges, and the potential costs of extending your lease or purchasing the freehold through collective enfranchisement. Crucially, it warns you about the marriage value threshold at 80 years, which can dramatically increase lease extension costs, and estimates how extending your lease could increase your property value. Whether you are considering buying a leasehold flat, already own one, or are weighing up enfranchisement, this tool gives you a clear financial comparison to inform your decision.
1. Enter the current market value of your property. This is used to estimate the property value increase that a lease extension would provide and to contextualise costs. 2. Enter the remaining years on your lease. This is the most critical input, as it determines the urgency of lease extension advice and whether marriage value applies (below 80 years). 3. Enter your annual ground rent. This is the amount paid to the freeholder each year as specified in your lease. Freeholders do not pay ground rent. 4. Enter your annual service charge. Note that service charges are typically paid by both leaseholders and freeholders of flats in managed buildings, so this cost may persist even after enfranchisement. 5. If you have received a quote for lease extension, enter it in the advanced options. If not, leave this at zero and the calculator will still compare ongoing leasehold vs freehold costs. 6. If you and fellow leaseholders are considering collective enfranchisement, enter your estimated share of the freehold purchase cost in the advanced options. 7. Review the results showing the 10-year cost comparison, ground rent savings, lease extension urgency advice, marriage value warnings, and estimated property value increase from extending the lease. The bar chart compares all cost elements visually.
The leasehold 10-year cost is calculated by multiplying the combined annual ground rent and service charge by 10. For example, if you pay GBP 300 ground rent and GBP 2,000 service charge annually, the 10-year leasehold cost is GBP 23,000. The freehold 10-year cost assumes that service charges continue (as is typical for flats in managed buildings) but ground rent is eliminated. So the freehold 10-year cost would be GBP 20,000 in the example above, giving a 10-year saving of GBP 3,000. The lease extension advice is based on the remaining lease term. Below 80 years is flagged as urgent because marriage value applies, making extension significantly more expensive. Between 80-85 years is flagged as recommended to act before the marriage value threshold is reached. Between 85-125 years, medium-term action is suggested. Marriage value is the increase in the property value that results from extending a short lease. Below 80 years, the leaseholder must pay the freeholder 50% of this value increase as part of the lease extension premium. This can add tens of thousands of pounds to the cost. The estimated property value increase is based on typical discounts that short leases apply to property values: approximately 10% below 80 years, 15% below 70 years, and 20% below 60 years. Extending the lease removes this discount, effectively increasing the property value.
The UK government has proposed significant leasehold reform through the Leasehold and Freehold Reform Act 2024, which aims to make it cheaper and easier to extend leases and buy freeholds. Key proposals include abolishing marriage value (reducing extension costs for leases under 80 years), standardising the calculation methodology, and capping ground rents on existing leases. However, many provisions are awaiting secondary legislation before they come into force. Collective enfranchisement allows qualifying leaseholders to jointly purchase the freehold of their building under the Leasehold Reform, Housing and Urban Development Act 1993. At least half the flats in the building must participate. Once the freehold is acquired, leaseholders can grant themselves new 999-year leases at a peppercorn rent, effectively eliminating ground rent and gaining full control of the building. The right to a lease extension (under the 1993 Act) is a statutory right for leaseholders who have owned their flat for at least two years. The extension adds 90 years to the current lease term and reduces the ground rent to a peppercorn. The cost (premium) depends on the remaining lease term, the ground rent, the property value, and the lease terms.
