Accreditation

SEDBUK is the average annual efficiency achieved in typical domestic conditions, making reasonable assumptions about patterns of usage, climate control, and other influences. The new boiler Building Regulations stipulate that only oil-fired condensing boilers rated band A or band B (A being the highest and most efficient) can be installed.
