A 60-day process that protects your right to recover the cost of major works through the service charge. Trigger calculator, draft notices, and damage-limitation steps if you missed it.
Section 20 sounds like a legal minefield. It is mostly a paperwork exercise with strict deadlines. The cost of complying is your time and a few stamps. The cost of skipping it is permanent loss of the right to recover anything above £250 per leaseholder.
For one-off qualifying works. Or £100 per leaseholder per year for any long-term agreement (over 12 months) such as a lift contract or grounds maintenance.
Two notices, 30 days each. Add another 30 if leaseholders nominate a contractor for you to obtain estimates from. Plan for 90 days end to end.
Other than your time and postage. The notice templates are below. Send by recorded delivery to each leaseholder at their flat address (and any nominated address).
Section 20 applies to two situations. Qualifying works: any one-off works (repairs, decoration, surveys, planned maintenance) where the cost to any single leaseholder will exceed £250. Qualifying long-term agreements: any contract over 12 months (managing agent, lift maintenance, cleaning, gardening, insurance brokerage) where the cost to any single leaseholder will exceed £100 in any single year of the agreement.
A clear yes or no, with the rule that triggered it. Use this before you instruct anything where the total cost is uncertain.
All figures are indicative ranges based on published rates checked April–May 2026. Always compare three written quotes for your specific building. Last reviewed for accuracy on the page legal-check date shown above.
Pick the card that matches you. Each one has a different next action.
You know roughly what the works will cost. The calculator above tells you consultation is required. Now you need to do it before you commit to any contractor.
What to do. Issue Stage 1 (Notice of Intention) using the template below. Allow 30 days for observations. Obtain estimates from at least two contractors plus any nominated by leaseholders. Issue Stage 2 (Notice of Estimates) with the estimates. Allow another 30 days. Then you can instruct.
You have issued at least Stage 1. You may have received observations or contractor nominations. The clock is running.
You commissioned the works and the per-leaseholder cost is now over £250. By default, you can only recover £250 per leaseholder. This is the most expensive mistake in leasehold management.
This is the long consultation procedure for qualifying works under Schedule 4 of the Service Charges (Consultation Requirements) (England) Regulations 2003. Same shape applies, with minor variations, for long-term agreements.
Send to every leaseholder at their flat address (and any other address they have nominated for service of notices). Recorded delivery is recommended. Also send to any recognised tenants' association.
The notice must describe the works in general terms, give the reasons, invite written observations within 30 days, and invite leaseholders to nominate a contractor for you to seek an estimate from.
You must consider any observations received. Obtain at least two estimates: one from a contractor independent of you (no connection to the landlord, manager, or directors), plus any nominated by leaseholders.
If a leaseholder nominated a contractor, you must seek an estimate from them or make a reasonable documented attempt to.
Send to every leaseholder. Include all the estimates obtained, a written summary of the observations received and your response, and at least the two lowest estimates in full. Invite further written observations within 30 days.
If you intend to award the contract to anyone other than the lowest bidder or a leaseholder-nominated contractor, you must explain why in the next stage.
Consider any further observations. Decide which contractor to award to. If you choose anything other than the lowest estimate or a leaseholder-nominated contractor, you must issue a Notice of Reasons within 21 days of awarding the contract.
Instruct your chosen contractor. Keep all the consultation paperwork, including signed proof of postage, every observation received, and copies of all notices. You will need this if a leaseholder challenges the recovery at the First-tier Tribunal.
Variations. Public notice (Schedule 1) applies if there is a tenants' association or the works are advertised on the public sector tender portal. Long-term agreements (Schedule 2) follow a similar shape with different timings. If your situation looks unusual, get specific advice. The Leasehold Advisory Service (LEASE) provides free guidance.
Both templates meet the prescribed content under the 2003 Regulations. Send to every leaseholder. Keep proof of postage. If you have a recognised tenants' association, send to them as well.
The penalty for not consulting is statutory and automatic. The tribunal can dispense with the requirement, but only on its own terms.
Under Section 20(1), if you fail to consult before instructing qualifying works over the threshold, your recovery from each leaseholder is capped at £250, regardless of the actual cost. If the per-leaseholder cost was £800, you can recover £250 and absorb the £550 yourself (or, in a director-managed company, the company absorbs it and the directors carry the cashflow problem).
You can apply to the First-tier Tribunal (Property Chamber) for dispensation from the consultation requirements. The tribunal will consider whether leaseholders suffered any actual prejudice from the lack of consultation. Genuine emergencies (urgent safety repairs, a roof in immediate danger) and inadvertent oversights are most likely to be granted dispensation, often with conditions such as paying the leaseholders' tribunal costs. Cynical or negligent failures are less likely.
Include the cost in your annual service charge demands or as a separate one-off demand. Each demand must include the Section 21B summary of rights and obligations or the demand is not legally enforceable. Reference the Stage 2 notice and the contract award in the year-end accounts. Keep all consultation paperwork on file for at least six years (the limitation period for service charge disputes).
The full statutory text is in the Service Charges (Consultation Requirements) (England) Regulations 2003. Free advice is available from the Leasehold Advisory Service (LEASE). For tribunal applications and dispensation, the First-tier Tribunal (Property Chamber) publishes guidance and forms.
