Autumn Home Maintenance Checklist for UK Homes (Printable)

Between mid-September and the end of November a British house is tested four ways at once: sideways rain, leaf fall, the first hard frost, and a heating system idle since March. Most emergency call-outs in January trace back to twenty minutes of work skipped in October — a silted gully, an unlagged condensate pipe, a gutter joint dripping since the summer.

The trouble with seasonal lists is that they hand you forty jobs and no way of knowing which six matter in your house. A 1930s semi with a cold loft has different weak points from a 2015 townhouse with a flat roof. Diagnose first.

Do it on a wet day; you learn more in one downpour than in a fortnight of dry weather. Take a torch and binoculars and fix nothing — the job is to sort the house into one of four problems, because the cures barely overlap. Date every photo: a stain the same size next February was old, one that has grown is live.

Work the block that matches your branch first. Branch two starts with damp and mould in UK homes, not a ladder; branch four is answered by draught-proofing your home, not by anything on the roof.

• •One, water getting in: brown tide-marked staining, damp high on a wall or round a chimney breast, blown plaster at the top of a bay. A gutter running over the fascia in the rain is the commonest single cause.
• •Two, water made inside: streaming windows, black speckled growth in corners and behind wardrobes, worst in bedrooms. Guttering is irrelevant here; ventilation, background heat and where you dry washing are not.
• •Three, heating uneven: cold at the top of a radiator is trapped air, a five-minute fix; cold at the bottom with a hot top is sludge, needing a £400-£700 power flush; one radiator stone cold is usually a seized thermostatic valve pin.
• •Four, the house heats but will not hold it: rooms cool within an hour, cold ankles at internal doors, under 270 mm of loft insulation. That is fabric, not boiler, and servicing will not change it.

Everything here keeps rain outside the envelope, and it wants doing before the leaves come down in the third week of October. Full method, including when a pole vacuum beats a ladder, in our gutter cleaning and maintenance guide.

• •Clear gutters, hoppers and downpipes — 1-2 hours DIY, or £70-£150 for a two-storey semi, £150-£250 for a three-storey terrace. Repeat after the main leaf drop.
• •Lift every gully grid, pull the silt out by hand, flush through — 20 minutes, free. A blocked gully throws water at the base of the wall and fakes rising damp convincingly.
• •Scan the roof from the ground with binoculars: slipped tiles, cracked cement fillets at the chimney, crumbling ridge mortar. Roofers charge £150-£350 minimum, so bundle jobs into one visit.
• •Finish exterior painting while daytime temperatures stay above 10°C; after mid-October most water-based products will not cure.
• •Scrub algae off paths and steps — an hour, £12-£18 for five litres of cleaner. Wet paving causes more autumn accidents than anything else outdoors.

Book the boiler service now — from the first cold snap Gas Safe engineers move to a two- or three-week wait. A standard service is £80-£140 and it is the one item here that genuinely is not DIY. The free work is yours: bleeding the radiators and re-pressurising the boiler takes about 45 minutes in a three-bed.

• •Run the heating 30 minutes on a mild day. A fault found now is a normal-rate repair; in December it is £90-£150 an hour at emergency rates.
• •Bleed every radiator from the top of the house downwards, then check boiler pressure reads 1.0-1.5 bar cold — 45 minutes, £2 for a key.
• •Reset the timer when the clocks go back, and set thermostatic valves room by room instead of leaving everything on 5.
• •Sweep the chimney before the first fire — £60-£100 per flue, with the NACS or HETAS certificate your insurer wants after a chimney fire.
• •Test smoke and CO alarms and check the date stamp. CO alarms expire at seven to ten years; replacements are £20-£30.

First inland air frosts usually arrive in the first fortnight of November, and the commonest winter boiler breakdown in Britain is not a component failure at all — it is a frozen external condensate pipe. Lagging costs about £10. Preventing and safely thawing frozen pipes covers the rest.

• •Lag the condensate pipe in Class O foam and tape the joints — 20 minutes, £8-£12. If it runs over a metre outside, reroute it internally: £100-£150 and it never freezes again.
• •Isolate and drain the outside tap, then fit an insulated cover — ten minutes, £6-£10.
• •Find the stopcock, label it, confirm it turns. Most seized stopcocks are discovered at 2am by someone standing in water.
• •Top loft insulation to 270 mm — £450-£700 in materials for a three-bed, £700-£1,500 installed. Check grant eligibility first.
• •Drain hoses and the mower, empty water butts to two-thirds so ice can expand.

Buy the consumables in one trip in early September; driving to a merchant mid-job is what turns a checklist into an abandoned one. Budget £60-£90 if you own none of it, plus £250-£400 for the bookings. Our annual home maintenance cost guide covers the full year. The winter-specific jobs continue in our winter home maintenance checklist, and the quick early-autumn version is the September home reset.

• •Bleed key £2, radiator brush £6, gutter scoop £8
• •Class O lagging and foil tape £12, outside tap cover £8
• •E-profile draught strip, 10 m, £8; door brush strip £10-£15
• •Path cleaner, five litres, £12-£18; stiff deck brush £8
• •Exterior wood preservative, five litres, £20-£30
• •Ladder standoff £25-£35 — it keeps the ladder off the gutter you are leaning on

Ranked by what skipping the job costs you in January, not by how satisfying it is.

• •Gutters and gullies. Water is the only thing here that destroys fabric while you sleep.
• •Condensate pipe and outside tap. Twenty minutes, under £20, and it prevents the two commonest cold-snap failures.
• •Bleed radiators, check pressure. Free, and it tells you whether you need an engineer at all.
• •Draught-strip both external doors. An hour and £25 for a difference you feel that evening.
• •Test the alarms and find the stopcock.

Three jobs earn a professional every autumn: the boiler service, which needs a Gas Safe engineer and is mandatory annually if you let the property; the chimney sweep if you burn anything; and a roof inspection if the house is over eighty years old or the binoculars found something you could not name. Booking early matters most for the sweep — chimney sweeping and log-burner prep explains what a proper sweep includes and why September slots go first.

Stop if the boiler loses pressure repeatedly after re-pressurising — that is a leak or a failed expansion vessel, not an airlock; if damp is wet to the touch rather than stained; if a gas flame burns lazy yellow instead of crisp blue; or if the work puts you above single-storey height in wind. A tower for a day is £150-£300.
