SEDBUK Boiler Efficiency

2 RatingsSEDBUK Energy Efficiency Bands
As a simple guide to efficiency, a scheme has been created with SEDBUK efficiency bands assigned to boilers on an "A" to "G" scale. The band is shown in the database and may be used on product literature and labels, though there is no requirement for manufacturers to do so. The scheme is temporary as it will be withdrawn when a European directive on boiler energy labelling is introduced.

| Old boiler (light weight) | 65% | £231 | £293 | £304 | £340 | £470 |
| New boiler (non-condensing) | 78% | £197 | £249 | £258 | £289 | £396 |
