Warmthwise is an independent guide to heating and energy saving for UK homes. We explain boiler fault codes, cold radiators, damp and mould, insulation and the grants and tariffs that can cut your bills.
How we work
Our guides are based on manufacturer manuals, Gas Safe and Ofgem guidance, and current UK schemes. We update articles when rules or prices change.
Safety first
Anything involving gas must be done by a Gas Safe registered engineer. We only describe checks a homeowner can safely make.
