How efficient is my boiler? - British Gas

The big savings come from swapping an old boiler for a new, high-efficiency one. SEDBUK 2005. The previous SEDBUK system is featured on older boilers and is still used by lots of manufacturers. Like the ErP system, it rates boilers from A-G. A-rated boilers score over 90% for efficiency, while G-rated boilers come in under 70%.
