In a speech by the Deputy Prime Minister, Nick Clegg, it has been revealed that the Green Invesment Bank may have a role to play in providing finance for the Green Deal. So far, detail is sparce, but it is speculated that the bank could play a role in offering finance at a lower rate of interest than commerical providers - something that may be important in the early years of the Green Deal to boost take-up and to enable a greater range of measures to fall within the confines of the "Golden Rule". While it is unlikely that such a role would be anything other than short-term, it could a vital 'primer' for the scheme, injecting momentum and helping to 'make the market' ahead of full participation by private financiers. A report is due out tomorrow which will provide further details of the Green Invesment Bank. Watch this space!
