The conduct of the evaluation relied on the assistance and co-operation of a large number of individuals and bodies. Above all, thanks are due to the tenants and householders who volunteered to take part - without any tangible incentive or gain to themselves - in a time-consuming schedule of interviews. Without the data provided by these respondents, the evaluation would have been impossible. We also acknowledge the efforts of the TNS fieldworkers who conducted the interviews.
Several Local Authorities and Housing Associations assisted in the identification of tenants included in the Central Heating Programme, who were potential candidates for the recruitment into the evaluation. The corresponding function was provided for private sector households by Eaga Group. We express our thanks to staff in all these organisations.
