If you can't get govt. Grants then don't bother. If paying full price the repayment period can be as high as 15 years. This is due to high electricity prices and **** feed in tarriffs. The most effective way to save money is insulation and draftproofing.
nah just did some drawings. it was a major **** of a job. went way over budget. think they had to sell it
Any time I watch grand designs I'm hoping the ****s go bankrupt. It's even more boring when the project goes to plan.
