40% of the country’s greenhouse-gas emissions. So as the government faces up to its obligation to reduce these by 80% (from 1990 levels) by 2050, it has proposed an ambitious plan to retrofit housing stock and business premises with energy-efficiency measures.</p><p>The Green Deal launches today, though that might be news to you: according to a YouGov poll last week, four out of five Britons have not actually heard of the deal. Given that politicians have spoken of improving 14m of the country's 26m houses, they have been careful to suggest that the deal is going to be a slow-burner. It is certainly starting off that way.</p><p>The idea behind the Green Deal is smart enough: householders and business owners will pay for energy-saving improvements—45 are currently eligible—through their electricity bill. They pay over the course of time, rather than in one wodge up front, and the money saved in energy usage should pay off the new debt. The loan stays with the property.</p><p>The process begins with a Green Deal assessor visiting the premises to work out what changes could be usefully made. According to the deal’s “Golden Rule”, only if the value of the savings over 25 years is greater than the cost of the proposed work does the scheme get the go-ahead. “Golden Rule” seems a mite bullish, though, for something that amounts to a guideline instead of a guarantee. After all, if your energy needs change—and particularly if they diminish—then you could end up paying more than you save.</p><p>The bill-payer takes the assessment plan to a Green Deal provider (or to several; shopping around is encouraged) who will arrange the work and calculate the terms of the repayment. The interest rate will probably be somewhere around 7%, based on the 6.96% rate at which the Green Deal Finance Company will lend to the providers.</p><p>Moves to transform the energy efficiency of Britain’s housing stock are worth applauding, but some aspects of the Green Deal will leave potential customers feeling a little queasy. Some will wonder whether in the current climate the government should be encouraging its electors to take on debt, even for environmentally beneficial ends. And it is unclear what effect the deal will have on the property market: some would-be buyers will not want to purchase properties burdened with large loans.</p><p>The fact that the £100-or-so cost of the assessors’ services will in many cases have to be paid up front will also put customers off. The government hopes to incentivise people to join the Green Deal by offering early participants money back. It has put £125m into a cashback scheme, which is available on a first-come-first-served basis. The first £40m of that will be given out per energy-efficiency measure according to a sliding scale (£250 for cavity wall insulation, for example, and £50 for draught-proofing). After that the rates are likely to reduce. Perhaps, as suggested by Labour’s Alan Whitehead in his <a href="https://web.archive.org/web/20130129050047/http://alansenergyblog.wordpress.com/2013/01/10/cashfront-vs-cashback-a-modest-proposal/" target="_blank">blog</a>, the money could be more wisely diverted towards funding the assessments.</p><p>And finally, the punitive interest rates will ensure that a lot of useful household improvement works simply will not qualify under the Golden Rule. When he was Secretary of State for Energy and Climate Change, Chris Huhne called the Green Deal "the most ambitious energy-saving plan ever put forward”. As it lurches into action this week, he may be relieved to be no longer involved.</p></div> <div id="block-ec_blogs-ec_blogs_block_prev_next" class="block block-ec_blogs"> <div class="content
