What is SEDBUK ?


The Seasonal Efficiency of Domestic Boilers in the UK rating scheme was developed in conjunction with boiler manufacturers and the government and provides a fair comparison of average boiler efficiency.

The model was developed to be a a more accurate method than laboratory tests alone as the theoretical data from test on 20 boilers in the labs was compared against field trials in 99 homes over a 3 year period.

A clear rating system is now applied to all boilers from A-G, A being the best and most efficient.
