Before the first frost

The winter checklist

  1. 01

    Lag exposed pipes

    Insulate pipes in lofts, garages and on outside walls before the first frost.

  2. 02

    Bleed the radiators

    Cold at the top means trapped air. Bleed each one, then re-check the boiler pressure.

  3. 03

    Check the boiler pressure

    Your boiler's manual gives the right cold pressure — top up through the filling loop if it's dropped.

Burst pipe?

Do this first

  1. 1

    Turn off the water

    Close the stop tap — usually under the kitchen sink or where the main comes in.

  2. 2

    Make it safe

    Switch the boiler off. If water is near electrics, stay clear and switch off at the consumer unit only if it's safe.

  3. 3

    Drain down

    Open the cold taps to empty the pipes and catch what you can with buckets and towels.

  4. 4

    Get it fixed

    Pick up repair fittings from the counter — or book an emergency plumber.
