Regulations to know
- No regulations for like-for-like swaps — gas work is only triggered if the boiler itself is touched
- Moving a radiator to a new wall is plumbing, not paperwork
Tips from the trade
- Swap several in one visit — the drain-down is the cost, not the radiator
- Fit thermostatic valves (TRVs) everywhere; they pay for themselves in a winter
