The Ultimate Autumn Home Maintenance Checklist for UK Homeowners

Autumn arrives quietly and then all at once. One week you're still eating dinner in the garden; the next you're hunting for the spare blanket and noticing a chill coming off the hallway floor. Homes rarely fail dramatically in December — they fail slowly, through a gutter that has been quietly overflowing since October.

The jobs below take a few weekends in total, and doing them now means you're working in mild weather and decent daylight rather than in the middle of a cold snap. Work from the top of the house downwards, and book any trades early: roofers, chimney sweeps and boiler engineers fill their diaries fast once the clocks change.

Start With Water: Gutters, Downpipes and Drains

Water causes more damage to British homes than cold does, and almost all of it arrives through somewhere it shouldn't: a blocked gutter, an overflowing hopper, a drain gully packed with leaves. Spend an afternoon here before you spend money anywhere else.

• Gutters. Clear leaves, moss and the beginnings of grass. Check that the brackets still hold the gutter at a slight fall towards the downpipe — a sagging run pools water and sends it down the wall.
• Downpipes. Run a hose into the gutter and watch where the water goes. If it backs up or dribbles down the outside of the pipe, there's a blockage.
• Gullies and drains. Lift the grate, scoop out leaves and silt, and check the trap isn't full of grit. A drain that smells is usually a dry trap rather than a serious problem.
• Water butts. Empty and rinse them, check the diverter and tap, and store them where they won't crack in a hard frost.

If you're using a ladder, put it on firm, level ground, keep it clear of overhead cables, and don't lean sideways to reach the last metre of gutter — move the ladder instead. If your gutters are high or the roof is steep, a gutter-cleaning service is money well spent.

Roof, Walls and Windows: A Look From the Ground

You can spot most external problems without climbing anything. Stand across the road with binoculars and look for slipped or missing tiles, cracked ridge tiles, sagging lines, and mortar that has crumbled around the chimney. Check the flashing where the roof meets a wall and where the chimney rises through it.

On the walls, look for new cracks in render, blown patches of paint, and air bricks that have been covered by a shrub or a raised patio. Air bricks ventilate the floor void; block them and you trap damp under the floorboards.

Then check the windows. Wooden frames need paint before winter, not after. Modern units need working hinges, intact seals and clear drainage slots at the bottom of the frame. If a pane has misted up between the layers of glass, the seal has failed and the unit will need replacing. Anything at height, and anything you're not confident about, is a job for a qualified tradesperson.

Draught-Proofing Without Sealing the House Shut

Draught-proofing is the cheapest comfort upgrade in the house. A cold draught under a door makes an otherwise warm room feel unwelcoming, and it pushes the heating on earlier than it needs to be. Start with the obvious gaps:

• letterboxes, keyholes and the bottoms of external doors
• gaps around window frames and between skirting boards and floorboards
• an open chimney in an unused fireplace
• the gap around a loft hatch or between a door and its frame

Brush seals, foam strips, silicone sealant and a decent door draught excluder will sort most of these for very little money. A chimney balloon stops warm air disappearing up an unused flue.

The important caveat: a house needs air. Don't seal up trickle vents, air bricks or extractor fans, and don't block ventilation in rooms with a gas boiler, gas fire or open flue. Seal everything and leave nothing to breathe, and you'll end up with condensation running down the windows and black mould in the corners. Keep bathrooms and kitchens ventilated and use extractor fans when cooking or showering.

Get the Heating Ready Before You Need It

Run the heating for twenty minutes on a mild afternoon now, while you can still get an engineer if something is wrong. A boiler that has sat unused all summer often shows its faults on the first cold morning of the year.

Bleed the radiators: if they're warm at the bottom and cold at the top, there's air inside. Turn the system off, open the bleed valve at the top of the radiator with a radiator key until water dribbles out, then close it. If you have to bleed the same radiator repeatedly, air is getting into the system somewhere and it's worth asking a heating engineer to look at it.

Check that thermostatic radiator valves turn freely, set the programmer for the hours you're actually at home, and make sure the thermostat isn't sitting above a radiator, in direct sun or behind a curtain. Gas boilers should be serviced annually by a Gas Safe registered engineer, and it's worth arranging that before the winter rush.

Insulation: The Jobs That Pay You Back

If you have a loft, look inside it. Insulation should be laid evenly across the joists and topped up if it's thin, but the eaves need to stay clear so air can move through the roof space. Insulation stuffed into the eaves is a common cause of damp timbers and condensation in the loft itself.

Lag hot water pipes and the cylinder if they run through a loft, garage or other cold space — lagging is cheap and easy to fit. Cold water pipes in the same places are worth wrapping too, before the first hard frost. Cavity wall and solid wall insulation make a real difference, but they're professional jobs; ask for a survey rather than guessing at what your walls need.

Outside, Safety and the Small Stuff

Finish by walking round the outside with a notebook.

• Put garden furniture away or cover it, clean the barbecue, and drain hosepipes before the first frost splits them.
• Turn off the outside tap at its internal isolation valve, then open the tap to drain what's left in the pipe.
• Cut back branches that touch the roof, gutters or overhead cables, and clear paths of wet leaves before they turn slippery.
• Empty plant pots and water features that could crack, and move terracotta under cover.
• Test smoke and carbon monoxide alarms, and replace batteries in any that aren't sealed units.
• If you burn wood or coal, have the chimney swept before you light the first fire, and keep logs somewhere dry.
• Check outdoor and security lights, and replace the bulbs you've been ignoring since spring.

Your Autumn Weekend Plan

If you'd rather not spend every spare hour on a ladder, do it in this order:

1. Clear gutters, downpipes and gullies.
2. Inspect the roof, walls and windows from the ground, and book any trade work.
3. Draught-proof doors and windows, leaving ventilation where it's needed.
4. Bleed radiators, check the controls, and book the boiler service.
5. Top up loft insulation, lag pipes, and protect the outside tap.
6. Test the alarms and sort the chimney.

Two or three weekends and it's done. Most years nothing will go wrong, and that's the point — the maintenance is what stops the drama. Where gas, electrics or structural work is involved, use a qualified professional rather than a tutorial and a hopeful afternoon.
