There has been much discussion recently in Parliament over the problem of financing the installation of renewable energy equipment on domestic premises.Most of which are unlikely to have the capital available for this.
The message below was sent recently to OFGEM, it may be of interest to you in the above context,

Ladies & Gentlemen,
Fuel poverty is often more common amongst those who have inefficient heating units and/or rely entirely on electricity. In an energy survey done over Orleton Village during 2007 it became clear that there were many in that category, especially in the ex council housing and other "sheltered" accommodation.

Heating & hot water are some four times a larger energy end use in UK than electricity for power/lighting. Why is it that there is much discussion about where more electricity may come from but little as to how the waste of this high energy source through it's conversion to low energy heating and hot water could be counteracted with environmental benefits ?

The large utility companies can benefit from the Enhanced Capital Depreciation Allowances for certain renewable energy equipment, so if they funded the purchase of heat pumps and solar water heaters, to be leased out to fuel poverty folk - and others possibly on a countering climate change basis - the total cost of such funding would come out of monies they would otherwise pay in taxes in the tax year after purchase. There would be no need to have special tarrifs which might reduce company profits, and all the environmental benefits from the installation would accrue to all premises so fitted.

The draft concept below has been circulated for comment, and was discussed at a meeting of the Marches Energy Agency on 28 April last. A positive meeting was held some weeks back with Sunrise Global Finance. On the basis of a possible project for the some 230 dwellings in Orleton Village.
yours faithfully

To reduce the UK’s electricity demand before consideration is given to new generating units
Based on an article in the Engineering for Buildings & Industry, March 2008, page 25 extract given below

The Carbon Trust reckons that as many as 80 per cent of all surveys commissioned through them that show opportunities for energy saving are not being implemented, even when they would produce very quick payback on any up front investment required. Internal finance rules designed to control an organisation's capital expenditure are having the effect of stopping energy- saving projects from being implemented. Huge potential savings are thus being lost. Interest free loans from the Carbon Trust don't solve the problem. In the article by Peter Thomas of Sunrise Global Finance an asset rental company has come up with an alternative way of financing such projects, and has funds available now.
Subject to the credit status of the organisation, Sunrise will pay for all aspects of the project, including implementation and consultancy charges, and rent the whole project installation back into the end client, usually on a five-year agreement. Technically, the arrangement qualifies as an "operating lease" and as such is accounted for "of balance sheet" by the client. They simply pay a quarterly rental out of the same operating budget that is benefitting from the energy saving. So it is net cost saving right from the start. Provided the energy-saving products being installed qualify under the Energy Technology List for Enhanced Capital Allowances, [ECA] Sunrise will play this into the rental payments so the client is not missing out on this aspect.

Householders while able to benefit from small grants, cannot benefit from ECA Nor from the now available 50% grants available for community projects under, so what is needed is a revision to the rules to enable Community Organisations, eg rural parishes, town wards, to set on the installation of Solar Water Heaters [SWH], and where appropriate Heat Pumps, in domestic premises within their community. To enable them to benefit from the grants and depreciation allowances available, and any quantity discounts for the supply and installation of the equipment.
The size of the opportunity may be gauged by a simple calculation. A single SWH unit will collect about 1500 kWhrs of energy in a year. If all 25 million UK houses were so installed, the annual energy collection would be similar to the output of 4-5 1000 MW power stations.
