In the latest statistics released by the Department of Energy and Climate Change (DECC), 7,465 assessments were made in March compared to 1,729 in February.
108 GD Assessor Organisations and the 1,003 GD Advisors they employ had been accredited, up from 77 and 618 at end February respectively.
£68.9 million worth of contracts had been let through the ECO brokerage system, compared to £26.9 million at end February.
On the figures, climate change minister Greg Barker said: “It is clearly very early days but the latest figures on the Green Deal show that this new market is gathering real momentum. 9,268 Green Deal assessments taking place in just over two months is very encouraging and shows a genuine interest from consumers. The Green Deal gives people the opportunity to improve the efficiency of their homes, make them warmer and protect themselves from rising energy bills.
“The number of businesses getting on board continues to rise steadily, underlining that the Green Deal offers fantastic new commercial opportunities. 48 firms are now authorised as providers, with a further 831 registered to carry out installations and over a thousand individuals registered to offer assessments. Overall this is a really promising start for the Green Deal.”
