All new gas boilers must have a minimum efficiency of 92% (ErP) — all modern condensing boilers exceed this. All our installations are notified under the Competent Persons Scheme. You will receive a Building Regulations Compliance Certificate within 30 days of installation.
Boiler sizing is measured in kilowatts (kW). As a rough guide: 1–2 bed flat: 24–25kW; 3 bed house: 28–30kW; 4–5 bed house with multiple bathrooms: 35–40kW. Our engineer calculates the correct size based on the number of radiators, hot water demand and heat loss calculations at the survey visit.
