It was very easy, I completed the on line application and it was approved instantly. In applying, you agree to the conditions of the grant, which includes stating that you have the required energy saving measures - insulation, low energy bulbs etc and that you agree to an inspection from the Energy Saving Trust (with reasonable notice).

Money for the grant is allocated monthly, January's had run out, so I stayed up and applied a few minutes after midnight on the 1st of Feb, to be certain, however information from the telephone helpline suggests that the money lasts till mid month before running out.

The grant is basically a 'cashback' after completion of the installation, together with a certificate of completion from the installer and receipted invoices for the work.
