Up to 37% of Leasehold Flats ‘Unmortgageable’ Due to High Service Charges: What London Landlords Must Do Now

Why High Service Charges Matter to Landlords

Recent research presented to MPs reveals that up to 37% of leasehold flats in England and Wales are effectively "unmortgageable" because their service charges exceed 1% of the property's value. Over the past decade, average service charges have surged by 56%, severely impacting the sales market for flats and trapping many leaseholders in costly arrangements.

For London landlords, where leasehold flats make up a significant portion of the private rented sector, this development has immediate practical consequences. Mortgage lenders are increasingly wary of financing flats with high service charges, reducing buyer pools and potentially affecting your property's market value. Tenants may also struggle with affordability if landlords pass on rising service charges, risking higher arrears or void periods.

Understanding the Mortgageability Threshold

The 1% service charge-to-property value threshold is a key benchmark cited by lenders. For example, on a flat valued at £300,000, annual service charges above £3,000 could trigger mortgage refusals. While research covers England and Wales broadly, London’s higher property values can sometimes mask steep absolute service charges—landlords should audit charges relative to their specific property values.

Implications for Different Landlord Profiles

• Single-Unit Landlords: A single leasehold flat with high service charges may face difficulties selling or refinancing, and tenants may push back on rent increases tied to service charge hikes.
• HMO Landlords: Houses in multiple occupation converting flats may encounter complex service charge apportionments and greater tenant affordability challenges.
• Portfolio Landlords: Large landlords must carefully monitor cumulative impacts across multiple leasehold flats, as rising service charges can significantly affect overall portfolio returns.
• Accidental Landlords: Those less familiar with leasehold complexities need to seek advice promptly to avoid unexpected financial exposure.

Freeholders and Ground Rent Caps: A Cautionary Note

Legal experts warn that some freeholders may try to circumvent recent ground rent caps by increasing service charges, further compounding leaseholders’ costs. This trend could escalate landlord expenses and complicate tenant affordability unless proactively managed.

Practical Steps Landlords Should Take Immediately

1. Conduct a Service Charge Audit: Review your flats’ current service charges against their market values. Identify any units where charges exceed the 1% mortgageability threshold.

2. Communicate with Leaseholders and Tenants: Transparently share information about service charge levels and potential impacts on financing and resale. Early communication can mitigate disputes and maintain good tenant relations.

3. Engage Professional Advice: Consult with property legal experts or specialist leasehold advisors to understand your rights and obligations, especially regarding leasehold reform developments and potential commonhold conversions.

4. Monitor Legislative Changes: Stay updated on government reforms targeting leasehold and commonhold tenure, as these may offer routes to reduce or control service charges in the future.

5. Adapt Letting and Sales Strategies: Factor in high service charges when setting rents and sales prices. Be prepared to explain to prospective tenants or buyers how service charges affect total occupancy costs.

6. Support Leaseholders’ Rights: Encourage leaseholders to seek independent legal advice about their options to acquire freeholds, convert to commonhold, or challenge excessive charges.
