London has more leasehold flats than anywhere else in the UK. By some estimates, around a million leasehold properties in Greater London are managed by freeholders and managing agents who control the service charge process. And because London construction costs are higher than the rest of the country, the sums involved in major works bills are correspondingly larger — and so is the potential for overcharging.
If you’re a leaseholder in a London flat and you’ve received a Section 20 major works notice, here’s what you need to know about how London-specific factors affect the picture.
London Construction Costs: What’s Legitimate and What Isn’t
It’s true that construction costs in London are higher than the national average. Labour costs are higher. Access is often more complex. Parking and logistics on congested London streets add genuine cost. These are real factors, and a legitimate major works bill in London will be higher than one for equivalent works in, say, Stoke-on-Trent.
The BCIS (Building Cost Information Service) publishes location factors that quantify this premium. For Central London, the typical location factor is 1.15–1.25 (i.e., 15–25% above national average). For outer London boroughs, it’s typically 1.05–1.15. For South East England, 1.00–1.10.
When we review London Section 20 bills, we apply the appropriate regional factor. What we often find is that managing agents apply a London premium that is significantly above what the published data supports — using “London is expensive” as a general justification for costs that are excessive even by London standards.
The Most Overpriced Works in London
Based on our experience reviewing London Section 20 bills, certain work categories are consistently overpriced:
- Scaffold in central and inner London: Logistically challenging and genuinely expensive, but we frequently see scaffold costs double or triple the expected rate. Always check the specification and duration.
- Communal redecoration: Simple painting work, even in London, should not cost £60/m². We see this regularly in prime areas where managing agents appear to assume leaseholders won’t check.
- Fire safety works: Post-Grenfell remediation has been a major source of inflated bills. Genuine fire safety work is necessary, but some managing agents have used it as cover for inflated specifications.
- External façade works: Cladding work, render repairs, and façade cleaning in London are frequently over-specified and over-priced.
London Leasehold: The Ground Rent Complication
Many London leasehold flats sold in the 2000s and 2010s carry escalating ground rents that may now be legally problematic under the Leasehold Reform (Ground Rent) Act 2022. While ground rent is a separate issue from Section 20 major works, it’s worth noting as part of the overall leasehold landscape: if you have an escalating ground rent, your flat’s marketability is affected, and the same freeholder who is charging ground rent is also the one serving Section 20 notices. Their financial interests and yours are not aligned.
London Residents’ Associations
London has some of the most active and experienced leaseholder residents’ associations in the country. If your block is large enough (and many London blocks are), forming or joining a Recognised Tenants’ Association gives you additional consultation rights, including the right to be consulted as a body rather than individually, and the right to request a management audit.
Organisations like the Leasehold Advisory Service (LEASE), the National Leasehold Campaign, and the Association of Residential Managing Agents (ARMA) all provide guidance and support specific to London leaseholders.
How Much Could You Save?
On a typical London major works bill of £30,000–£60,000 per leaseholder, the potential savings from a successful challenge are significant. We have seen London leaseholders recover £15,000–£25,000 per flat through tribunal proceedings or negotiated settlements — figures that comfortably justify the cost of professional assessment and (if necessary) tribunal proceedings.
Don’t assume London prices are inevitably high. They should be higher than average — but they should still be reasonable. And “reasonable” is a standard that managing agents regularly fail to meet.
