Aga-Rayburn and trade bodies including the society of British Gas Industries (SBGI) and the Oil Firing Technical Association (OFTEC) have led the way in liaison with the Government over improving the efficiency standard of 75 per cent or above on range cookers.

For new-build properties, a website provides data to enable Standard Assessment Procedure (SAP) assessors, such as architects and consultants, to find the exact figure needed for their SAP calculations to ensure the new-build meets the approved energy rating levels set down by the Government.

Rayburn – which leads the way in the efficiency of central heating range cookers declares the efficiency of its product range on this website. For more information visit -  http://www.rangeefficiency.org.uk/ – which is fully endorsed by SBGI, OFTEC and HETAS.

The requirement in England and Wales (April 2007) for oil fired central heating boilers to be of the condensing type, does not apply to range cookers, which continue to be compliant.
