How to Prepare Your Home for Winter in the UK

A practical six-step plan to get a UK home ready for winter, covering heating, insulation, pipes, roof, drains and what to do if you are renting.

Preparing your home for winter is mostly about three things: keeping heat in, keeping water out and keeping pipes from freezing. If you only have a few hours or a small budget, this guide shows which steps give you the most protection per pound spent. It is more focused than a full seasonal checklist, so see the autumn checklist if you want every small job.

Step 1: Make sure heating works before you need it

Turn the heating on for a test run in September or October, not during the first frost. Check that every radiator warms up and that the boiler fires on demand.

  • Bleed radiators if the top is cool.
  • Book a boiler service with a Gas Safe registered engineer. Servicing finds faults early and is often a requirement of manufacturer warranties.
  • Check your controls: timers, thermostat batteries and TRVs.

If the boiler loses pressure, makes banging noises or needs resetting often, ask for a repair before the cold arrives.

Step 2: Stop heat escaping

Heat leaves a home through the roof, walls, windows and gaps. Prioritise in this order:

  1. Loft insulation: Typically the best-value upgrade for a house with an uninsulated or thin loft. The usual recommendation is around 270mm of mineral wool, but check what is already there.
  2. Draught-proofing: Doors, letterboxes, keyholes, skirting boards and floorboards. Our draught-proofing guide shows what is worth doing.
  3. Curtains: Thick, lined curtains reduce heat loss at windows. Close them at dusk.
  4. Radiator reflectors: Foil behind radiators on external walls reflect some heat back into the room.

Do not seal permanent ventilation, such as air bricks, trickle vents or extractor fans. Homes need a controlled air flow to reduce condensation and to keep fuel-burning appliances safe.

Step 3: Protect pipes

Frozen pipes cause a surprising amount of damage because the water expands and cracks the pipe, then floods when it thaws.

  • Insulate pipes and tanks in the loft, garage and outbuildings with foam lagging.
  • Fix dripping taps, because a trickle can freeze.
  • Know where the stop tap is and make sure it turns.
  • Leave the heating on a low setting if you are away.
  • Open the loft hatch during very cold spells so some warmth reaches the tank.

Step 4: Keep water moving away

Wet and cold together damage masonry fast. Clear gutters, downpipes and drains in late autumn, and check that water from gullies and downpipes goes to a drain, not against the house wall. Check the roof from the ground for slipped tiles.

Step 5: Prepare for power cuts and bad weather

Store a torch, spare batteries, a power bank, warm blankets and some long-life food. Know the number 105 for reporting power cuts, and keep a list of key phone numbers on paper in case your phone has no battery.

Step 6: Look after people, not just the property

If you have older or vulnerable relatives or neighbours, check the heating works and that they know who to call. Our home safety for older people guide covers other items.

If you are renting

Many of these jobs belong to your landlord, such as boiler servicing, roof and external repairs, and structural insulation. Your responsibilities generally include day-to-day things like testing alarms, reporting problems promptly and heating the property sensibly. Report issues in writing and keep a copy. See tenant vs landlord repair responsibilities.

Budgeting

You do not have to do everything in one go. Rank the jobs by risk first, then by payback. A boiler service and lagging are cheap and prevent expensive failures; loft insulation costs more but pays back over time.

For help with any of these jobs, you can find local providers on Compito, compare ID-verified professionals by postcode and send a request.

A worked example: a one-weekend plan

Saturday morning: test heating, bleed radiators, check TRVs and set the timer. Saturday afternoon: fit foam lagging to pipes in the loft and garage, check the stop tap, put brush strips on the front door and letterbox. Sunday morning: clear gutters and gullies, trim branches and secure loose fence panels. Sunday afternoon: assemble a small storm kit with a torch, batteries and a power bank, and put the number for the boiler engineer on the fridge. None of it is glamorous, but it covers the main failures: no heat, frozen pipes, overflowing water and no light.

What to check if you are going away in winter

  • Leave the heating on at a low frost setting, or drain the system if the home will be empty for a long time and you know how.
  • Ask someone to look in every few days.
  • Leave the loft hatch closed unless advised otherwise, but make sure tank and pipes are insulated.
  • Leave contact numbers and the stop tap location with your key holder.

Garden and outdoors

Drain and cover outside taps, clean and store hoses, protect tender plants, check that paths and steps are not slippery and have a plan for ice, such as grit or sand. Move bins, bikes and furniture away from walls so water can drain and so you can access the property safely.

Winter warmth on a tight budget

If money is tight, start with free actions such as closing curtains at dusk, using rooms you need and keeping doors shut. Cheap actions come next: draught strips, radiator foil, lagging. Then speak to your supplier or council about support, and check eligibility for any schemes on gov.uk. Be cautious about unsolicited offers by phone or at the door.

Frequently asked questions

When should I start preparing my home for winter?

Ideally in September or early October, before temperatures drop and trades become busy. It is still worth starting in November if you are late.

What is the single most important winter prep job?

For most households it is having the boiler serviced and knowing where the stop tap is. Together they cover the most common and costly emergencies.

Are there grants for insulation?

Government and energy company support schemes change over time and have eligibility rules. Check gov.uk and your energy supplier for current options.
