Twelve Jobs to Tick Off Before the First Frost (and What Each One Really Costs in 2026)

There is a particular kind of November panic that arrives the moment a hard frost appears in the forecast. Suddenly everyone is buying pipe lagging at 9pm and ringing a roofer who will not answer until March. Let us be clear about something: most of this list is not urgent. A half-blocked gutter is not an emergency. But a dozen small jobs done on a damp Saturday in early November will quietly save you a much larger bill in January.

So here is the sensible order of priority, roughly what each job costs in 2026, and — just as usefully — what you can cheerfully ignore until spring.

Start with water, because water is what does the damage

If you only do three things this month, make them the three below.

Clear the gutters and check the downpipes. Blocked gutters are the single most common cause of damp patches on upstairs walls, and the water goes straight down the cavity rather than where you want it. A professional clear on a typical three-bed semi runs £120 to £250, including a check of the joints. It is free if you own a sturdy ladder and a head for heights, but not on a wet day and not alone.

Lift the drain gullies. Put on gloves, lift the grid outside the kitchen or by the driveway, and scoop out the silt and leaves. A blocked gully in a cold snap is how you get a flooded patio. Ten minutes and no money.

Have a look at the roof — from the ground. Binoculars, garden, no ladders. You are looking for missing or slipped slates, sagging lines and ridge tiles that have shifted. A roofer's inspection costs £150 to £250 and a small repair £150 to £400. Crucially, do not get up there yourself in November.

The heating appointment you should have made in September

A boiler service is £90 to £130 and must be done by a Gas Safe registered engineer. Ask them specifically to check and lag the condensate pipe, because a frozen condensate is the classic reason a boiler refuses to fire during a cold snap — and it is a £15 fix when it is done in advance. While the engineer is there, get the radiators bled (free), confirm the system pressure sits somewhere around 1 to 1.5 bar, and make sure the thermostatic valves are not stuck shut.

If your boiler is 15 years old or more, this is the month to start a replacement fund rather than waiting for it to fail in February. A like-for-like combi swap is typically £3,000 to £4,500 in 2026. If you have a hot water cylinder, a decent lagging jacket is £25 to £40 and pays for itself surprisingly fast.

Loft, draughts and the 270mm rule

Current guidance is around 270mm of loft insulation. Plenty of UK houses still have 100mm, laid decades ago by someone who thought they were being thorough. Topping up a typical loft runs £300 to £600 if you do it yourself and £500 to £900 fitted. It is a mucky, itchy job but a straightforward one. Do not, however, block the eaves — you need that ventilation to stop condensation and rot.

Draught-proofing is the cheapest comfort upgrade in the house. A chimney draught excluder is £20 to £40 (but do not block a working flue without a sweep's advice), and a whole-house kit of letterbox, keyhole and window seals is £50 to £150. A Saturday's work. If you have a cold spare bedroom with sound frames, secondary glazing film at £15 will do more than a set of new windows at £6,000.

Outside: taps, pipes and things that crack

Isolate and drain the outside tap. If there is no isolation valve, fit one — the part is around £10 and a plumber will charge £60 to £100 to fit it, or you can do it yourself if you are confident with a spanner. An outside tap that freezes with water in it can split the pipe inside the wall, which is a far more expensive afternoon.

Lag any exposed pipework in the garage, outbuilding or along a north-facing wall with foam lagging at £10 to £20 a pack. Clear leaves from patio drains so rainwater has somewhere to go. And after the first named storm, walk the boundary and check fence posts — a panel that is loose now will be in next door's garden by December.

The five-minute jobs everyone forgets

• Find the stopcock. Turn it, then turn it back. If it is seized solid, get it replaced — £80 to £150 — and label it. In a leak, knowing where it is saves ceilings.
• Test the smoke and carbon monoxide alarms. Batteries are £5.
• Read your insurance policy's exclusions. Many policies will decline escape-of-water claims where a leak has clearly been ignored for months. Maintenance matters contractually, not just practically.
• Photograph the boiler installation date and your meter readings. Boring, useful.

What can honestly wait until spring

Repointing cosmetic brickwork. Painting render or exterior wood — below 5°C you are simply wasting paint. Replacing a fence panel that is still standing. Garden landscaping. Sorting out a mossy lawn. None of it will hurt you over winter, and all of it is nicer to do in April with a cup of tea in hand.

A rough budget sketch

If you did the whole list professionally — gutters, boiler service, roof check, insulation top-up and a bit of lagging — you would be looking at somewhere between £900 and £1,800. Doing the DIY-able half yourself brings that down to more like £400 to £700. That is the realistic figure to plan for, not the four-figure sums quoted by anyone trying to sell you a full exterior package in a panic.

The trick with November is to treat it as admin rather than a crisis. Twenty small decisions now, all of them cheap, and winter becomes a season you get through rather than one that surprises you.
