Section 20: consultation before major works
Before major works where any one leaseholder would pay more than £250, the landlord must consult the leaseholders (Landlord and Tenant Act 1985, section 20, and regulation 6 of the Service Charges (Consultation Requirements) (England) Regulations 2003; Wales has its own 2004 Regulations with the same threshold). The same applies to long-term agreements where any one leaseholder would pay more than £100 in a year. Whoever runs the block, landlord, RMC or RTM company, has to follow it.
| Stage | What you get | What you can do |
| 1. Notice of intention | A description of the works and why they're needed. | Send written observations, and nominate a contractor to be asked for an estimate, within 30 days. |
| 2. Statement of estimates | At least two estimates. At least one must be from a contractor wholly unconnected with the landlord. | Send written observations on the estimates within 30 days. Ask to see the estimates in full. |
| 3. Notice of reasons | If the contract goes to someone other than the lowest bidder or a leaseholders' nominee: the reasons, within 21 days of signing. | Read it, and keep it with the other notices. |
If the consultation isn't done, what can be recovered from each leaseholder is limited to £250 unless the landlord asks the First-tier Tribunal to excuse it (this is called dispensation, under section 20ZA). The tribunal often grants dispensation, sometimes on conditions, so the point is to use the consultation: comment in time, and keep copies.
Paying only what's reasonable
Service charges are payable only to the extent they are reasonably incurred, and for works or services of a reasonable standard (section 19). Either side can ask the tribunal to decide what is payable (section 27A).
The 18-month rule
If a cost was incurred more than 18 months before you were sent a demand for it, you don't have to pay it, unless within those 18 months you were told in writing that the cost had been incurred and you would be asked to contribute (section 20B).
Your right to information
You can ask in writing for a summary of the service charge costs (section 21), and then, within six months of getting it, ask to inspect the accounts, receipts and other documents behind it (section 22). The letters below do both.
Where disputes go
In England, the First-tier Tribunal (Property Chamber). In Wales, the Leasehold Valuation Tribunal, part of the Residential Property Tribunal Wales. LEASE, the government-funded Leasehold Advisory Service, gives free initial advice.
General information only, current to September 2026. The Leasehold and Freehold Reform Act 2024 will change several of these rules, including service charge information, when those parts are brought into force; check legislation.gov.uk for the current text and ask a solicitor about your own situation.
