Every year around now, someone forwards me a long-range winter forecast and asks whether they should be worried. I never know how to answer that, because I don't know what February will do and neither does anyone else with real certainty. What I do know is that the difference between a hard winter and a miserable one usually comes down to a handful of small jobs nobody feels like doing in November, when it's dark at five and raining sideways. Late summer is when they're easy. The light is still good, the ladder isn't slippery, and you can leave a door open while you work.
So instead of reacting to the forecast conversation, I keep a short list. It takes two or three unhurried afternoons across September, and it makes the cold months noticeably cheaper, quieter and less stressful.
Start with the air, not the thermostat
Most homes don't feel cold because the heating is inadequate. They feel cold because warm air is leaving and cold air is arriving in a slow, invisible exchange. Go around on a still day with the back of your hand and check the obvious suspects: the letterbox, the gap under the front door, the keyhole, the frame of a window that never quite closed properly, an unused chimney, the hatch to the loft.
Fixes are mostly humble. A draught brush on the bottom of the door. Self-adhesive foam strip in the window rebate, pressed on clean, dry paint so it actually sticks. A rolled towel at the base of a room you don't use. Adjust the little cam on your window handles to the winter setting if they have one — many do, and hardly anyone touches them. And check the heavy curtains you already own: hung so they end just below the sill or reach the floor, closed at dusk rather than at bedtime, they behave like a second wall.
The half-hour outside that saves a January headache
Gutters and downpipes are the whole ballgame. Leaves are only beginning to drop now, so plan a clear-out at the end of leaf fall too, but get the summer debris out while the weather is kind. Pour a bucket of water into the gutter and watch where it goes; if it pools or spills at a joint, you've found the thing that would have frozen and cracked.
While you're out there: clear the drain or gully by the back door so the first heavy rain doesn't come inside, disconnect and drain the outside tap and hose so nothing freezes and splits, and give garden furniture a wash before you cover it, because dirt left on wet wood over winter turns into a green film that takes twice as long to remove in spring. Put whatever you use for icy paths — grit, sand, ash — somewhere you can reach without walking across the ice to get it. Sounds obvious. It's the single most-forgotten item on the list.
Bring the growing season indoors
If you garden on a balcony or in pots, the next few weeks decide what you'll still have in December. Take cuttings of anything tender you'd hate to lose and root them on a windowsill. Move pots off cold stone onto a wooden board or pot feet so roots aren't sitting in standing water. Cut back the herbs you want to keep, bring one pot of parsley or thyme inside where you'll actually use it, and mulch the containers that stay out with compost or leaf litter — it's insulation, not decoration.
This is also the moment for spring bulbs. Planting them is the least fashionable job of the year and the one that pays the biggest emotional dividend: something arriving in March that you decided on in September.
The soft layer nobody plans for
Warmth is partly textile. Before the first cold night, wash and air the heavy bedding, get the wool blankets out of storage so they lose their cupboard smell, and put a proper mat and a boot tray by the door. Move the reading lamp to the chair you'll actually sit in when it's dark early. If you have a rug rolled up somewhere, unroll it — a hard floor in an unheated hallway makes a whole flat feel colder than it is.
What should I do first if I only have one free afternoon?
Do the draught check and the gutter check, in that order. Sealing the gaps around doors and windows gives you comfort you'll feel the same evening, and clearing the gutters prevents the kind of water damage that costs real money later. Everything else on this list is improvement; those two are protection.
Is it worth buying anything, or can I do this with what I have?
Almost all of it is free. The only things worth acquiring are cheap and reusable: a roll of draught-excluder foam, a door brush, and a bag of grit or sand for the path. Beyond that, resist the urge to buy your way into feeling prepared — a spare blanket you already own and a clear downpipe will do more for you in January than anything you order online this week.
