Section 20 and facade works: a managing agent’s guide
Facade cleaning, render repair and masonry restoration on a managed block routinely cross the Section 20 threshold, which means a formal leaseholder consultation before you can recover the cost. This is what triggers it, the stages you have to follow, and how to scope and price the work so the consultation is clean and defensible.
What Section 20 is and when facade works trigger it
Section 20 of the Landlord and Tenant Act 1985, as amended by the Commonhold and Leasehold Reform Act 2002, requires a landlord or managing agent to consult leaseholders before qualifying works go ahead. The trigger is simple: works qualify if any single leaseholder would pay more than £250 towards them through the service charge. On most blocks a facade clean, a render repair or a masonry restoration clears that threshold easily once the cost is divided across the building. In practice the consultation is the rule, not the exception.
If you carry out qualifying works without consulting, your ability to recover the cost from leaseholders is capped at £250 each, regardless of what the work actually cost. That is the risk that makes the process worth getting right, and it is why the scope and the estimates matter as much as the consultation notices themselves.
The qualifying works threshold
The trigger is per leaseholder, not per building. Divide the likely cost across the contributing leaseholders and if any one of them passes £250, the works qualify. A separate regime covers qualifying long term agreements, where any leaseholder pays more than £100 a year. That can catch a multi year planned maintenance contract for cleaning a facade on a cycle.
Because access drives facade cost so heavily, a job that looks modest can still cross the threshold on a smaller block. It is safer to assume consultation is required and confirm otherwise than to find out after the work that recovery is capped.
The consultation stages
For qualifying works without a long term agreement, the process runs in two notice stages with an observation period after each. Stage one is the notice of intention. It tells leaseholders the works are proposed, describes them in general terms, and invites observations and nominations of a contractor over a period of at least thirty days.
Stage two is the notice of estimates. You obtain estimates, including one from a contractor wholly unconnected to the landlord and any nominated by a leaseholder. You then set out the estimated costs and again invite observations over at least thirty days. You must have regard to the observations you receive. Where you do not appoint the lowest estimate or a leaseholder nominated contractor, a further notice explaining the reasons is required.
The detail of notice content and timing is prescribed, and a tribunal can dispense with consultation in limited cases. The safe operating assumption is two stages, two thirty day windows, and at least two genuine estimates one of which is independent.
How to get clean, comparable estimates
The part that derails a Section 20 consultation is usually the estimates, not the notices. Estimates that price different scopes, use different access methods, or quote a day rate against a fixed price are not comparable. A leaseholder challenging the charge will say exactly that. What you want is two or more specialists pricing the same defined scope, on the same access basis, as a fixed price with the method stated.
This is where a specialist helps rather than hinders. Envelium is an independent building envelope specialist. You tell us the building and the scope once, and we put it to vetted, IRATA certified, insured specialists who cover your area. The estimates come back on a like for like basis with the paperwork attached. One of those estimates is, by definition, from a contractor unconnected to you, which is exactly what stage two asks for.
Common mistakes that cap recovery
The recurring errors are familiar. Starting the works before the second stage closes. Treating a planned maintenance contract as a one off and missing the long term agreement rules. Accepting estimates that are not genuinely comparable. Failing to have regard to leaseholder observations in writing. Each of these is the kind of thing a First-tier Tribunal looks at when a charge is challenged.
None of this is a reason to delay necessary work on a deteriorating facade. It is a reason to scope it properly, get comparable fixed price estimates early, and run the two stages in parallel with the survey. That way the building is not waiting on paperwork.
Frequently asked
Do facade cleaning and repair works need a Section 20 consultation?
Usually yes on a managed block. If any single leaseholder will contribute more than £250 towards the cost through the service charge, the works qualify and a consultation is required. Because access makes facade work expensive, that threshold is normally crossed once the cost is split across the building.
What happens if I skip the Section 20 consultation?
Your ability to recover the cost from each leaseholder is capped at £250, no matter what the work actually cost, unless a tribunal grants dispensation. That is the main financial risk and the reason the process is worth following.
How many estimates do I need for Section 20?
At least two, and at least one must be from a contractor wholly unconnected to the landlord or managing agent. If a leaseholder nominates a contractor, you must try to obtain an estimate from them too. The estimates should price the same scope so they are genuinely comparable.
How long does a Section 20 consultation take?
Plan for two stages with an observation period of at least thirty days after each, so roughly two to three months including the time to gather comparable estimates. Running the survey and estimates alongside the notices keeps it as short as possible.
Does Envelium carry out the works?
Yes. We use vetted, insured, IRATA certified specialists who cover your area, and we put your scope to more than one of them. That gives you the comparable, independent estimates Section 20 requires.
Need comparable estimates for a Section 20 facade job?
Tell us about the building and you get a vetted specialist who covers your area. A surveyor comes back with a fixed price, usually within one working day.
