Do you need scaffolding for chimney repairs?

The stack rises from the ridge or the roof slope, often several metres above the eaves and higher still on a tall Victorian house. Working there means standing on a sloping, slippery surface while handling heavy loads: bricks, mortar, rolls of lead and clay pots, all of them awkward to pass up by hand. A ladder against the gutter is not a platform, and it cannot safely take a bucket of mortar or a new pot.

Scaffold gives a level deck around the stack, edge protection so nobody slips off the side, and a lift route for materials. It protects the people working above, and with boards or a fan it protects anyone walking or parking below from dropped debris. Brickwork, flashing and flaunching repairs can all share the same scaffold, so the full repair is done in one visit rather than several partial ones, and the roof is left properly finished.

Not every job needs a full scaffold up the front of the house. A low stack on a bungalow, a single-storey extension or a rear slope can sometimes be reached from a tower, a mobile access platform or a properly secured roof ladder. A small pot replacement or a patch of pointing might be done that way when it is safe.

That decision comes from the survey, not from the price. We look at the height, the pitch, how sound the roof covering is and the condition of the stack, then recommend the least access that keeps the work safe. Skimping on scaffold is where accidents and poor repairs begin, so if the stack is tall, steep or crumbling, the answer is proper scaffold and the photographs show why. For the repairs themselves, see repointing and the stack rebuild.

Section 169 of the Highways Act 1980 makes it an offence to put up scaffold that obstructs a highway without the highway authority's licence. The authority for Arun, Chichester and Worthing is West Sussex County Council, which wants at least 10 working days between applying and erecting and prices a one-month licence at £266. Across the border, Hampshire County Council looks after Havant and East Hampshire, requires no fewer than ten clear working days before the start date and charges £211.90 for the first two weeks. Portsmouth falls to the city council as its own highway authority.

That notice period is why a start date often falls a week or two after you accept. West Sussex also lists a fast-track option for an extra £52. A scaffold kept entirely inside your boundary does not need the highway licence at all. Which case applies to your house is something we work out on the day of the survey, so the delay does not catch you out.

Scaffold is a real part of a chimney job, and the figures below are national guides, not our quotes. Checkatrade's scaffolding cost guide, updated in 2026, gives chimney scaffold at around £660 per week and council permits at approximately £140 per month. MyJobQuote's guide to chimney lead puts a full set of flashings at £350 to £460 without scaffold and £700 to £920 with it, which shows how much access can add to a modest repair.

So ask every roofer who quotes you whether the price includes scaffolding, and whether it includes VAT. Our price is put in writing after we have inspected the roof. Where several jobs fall on the same elevation, such as gutters, fascias and chimney work, doing them in one visit makes better use of the same scaffold. Our chimney repair cost guide gives the wider picture.

Scaffolders erect and dismantle the scaffold, and the roofers use it as a platform. Once the scaffold is in, it is inspected before anyone climbs it, and any cover, boards or netting are checked at the same time. Tell your neighbours before it goes up, as it may stand on or near their boundary, and think about your car, your bins and pedestrian access. Close the windows on any elevation it covers, since dust and mortar splashes are part of any building job.

When the repair is finished the scaffold comes down, the rubbish is taken off site and the roof is left tidy. Photographs of the finished stack are yours to keep. If you are wondering how long the whole job runs, licence wait included, read our guide on how long chimney repairs take, and the chimney repairs hub lists what each repair involves. Whatever the access, the first thing we do is look at the stack and give you a plain verdict.
