Extending your lease is one of the most important decisions you'll make as a leasehold property owner. With professional valuation and the right approach, you can secure significant additional years on your lease while protecting your property's value and your investment.
Our specialist lease extension surveyors at Putney Surveyors have helped hundreds of leaseholders across West London navigate the extension process successfully. This comprehensive guide explains everything you need to know about lease extensions, valuations, and how to secure the best possible terms.
Understanding Lease Extensions
A lease extension increases the length of your leasehold, typically adding 90 years to the remaining term while reducing the ground rent to a peppercorn (effectively zero). This process can add tens of thousands of pounds to your property's value.
Why Lease Length Matters
Property Value Impact
- Below 80 years: Significant value reduction begins
- Below 70 years: Major mortgage restrictions
- Below 60 years: Severely limited marketability
- Below 30 years: Property becomes almost unsellable
Value Loss by Lease Length
- 80-70 years: 5-10% value reduction
- 70-60 years: 10-20% value reduction
- 60-50 years: 20-30% value reduction
- Below 50 years: 30%+ value reduction
Two Types of Lease Extension
Statutory Lease Extension
Legal Right: Leasehold Reform Act 1993
Requirements:
- Owned the lease for at least 2 years
- Property is a flat (not a house)
- Building contains no more than 25% commercial space
Benefits:
- Legal right - landlord cannot refuse
- Standard terms (90 years + peppercorn rent)
- Tribunal protection if needed
Voluntary Extension
Negotiated: Agreement with freeholder
When Used:
- Don't qualify for statutory right
- Want different terms (e.g., longer extension)
- Prefer to negotiate directly
Considerations:
- No legal right - freeholder can refuse
- Terms are negotiable
- May be more or less expensive
Lease Extension Valuation Process
The premium you pay for a statutory lease extension is calculated using a specific legal formula that considers several factors. Understanding this helps you prepare and negotiate effectively.
Valuation Components
1Diminution in Value of Freeholder's Interest
The reduction in value of the freeholder's interest due to the lease extension.
- Current ground rent - Capitalized value of rent stream
- Reversion value - Property value when lease expires
- Deferment rate - Usually 5% for prime central London
2Landlord's Share of Marriage Value
Applies only if lease has under 80 years remaining
- Marriage value - Increase in property value from extension
- 50/50 split - Landlord gets half the marriage value
- Major cost factor - Can be £20,000+ in West London
3Compensation
Additional payments for specific losses to the freeholder.
- Legal and valuation costs - Freeholder's professional fees
- Administrative costs - Processing and management
- Loss in value - Any other provable losses
