How do I know what size radiator I need?

It depends on the room's size, how well it is insulated, how many outside walls and windows it has, and the temperature you want it. A heat loss calculation, or a reputable online BTU calculator, gives the output needed in watts or BTU per hour. As a rough guide, a small bedroom often needs around 2,000 to 3,500 BTU and a living room 5,000 to 8,000 BTU, but older, draughty or north-facing rooms need more.

Before you book: a quick St Austell checklist

Measure the width and height of each radiator and the distance between the pipe centres
Note any rooms that are always cold, as they may need a bigger radiator rather than a like-for-like swap
Find out whether your system is sealed (pressure gauge on the boiler) or open-vented (tank in the loft)
Say if you are planning a heat pump, so radiators can be sized for lower flow temperatures
Decide whether you want new TRVs on every radiator being replaced
