The Community Energy Saving Programme (CESP) ends on 31 December 2012 and will be followed by the energy company obligation (ECO). The Government have no intention of extending the deadline for achievement of the targets under CERT and CESP beyond the end of this year. To help the transition between the schemes it is planned that the ECO should come into effect from October this year.Where work on a CESP scheme is completed after 31 December 2012 it can be used to help meet a company's obligation under the ECO, as long as the measures concerned would also qualify under the ECO.
