Turn your heating on for ten minutes this week. Not because it's cold — because if something's wrong, September is a much better month to find out than November.
Then walk round the house and put a hand on every radiator, top and bottom.
Cold at the top, warm at the bottom: that's air. Bleed it. Key in the valve at the top corner, quarter turn, catch the drip with a cloth, close it as soon as water comes instead of hiss.
Cold at the bottom, warm at the top: that's not air, and bleeding it won't do anything. That's sludge settled along the bottom of the radiator. It needs looking at properly rather than fiddling with.
A radiator that's stone cold all over, with a TRV on it: try lifting the head off and pressing the little pin underneath. They seize up over the summer when they've sat open all season. Half the time it drops back down and the radiator comes to life.
While you're at it, look at the pressure gauge on the boiler. There's a normal range marked on the dial — check yours is sitting in it while the system's cold, and if it isn't, that's worth a conversation before the cold weather.
And check the towel rail. Everyone forgets the towel rail.
Anything you need — bleed keys, TRVs, lockshields, spares — we're on Woodlands Road and you don't need an account.
