To insulate an existing wall, you are looking at 3 major options: external wall insulation, interior wall insulation and cavity wall insulation. Whichever method you choose, the insulation needs to be put in place with the utmost care. Poorly applied insulation may cause mould problems or 'cold bridges’, i.e. points where the insulation barrier is interrupted.
The dual hourly rate is based on the principle of two different prices for electricity: during the daytime it is slightly higher than the single rate, while at night as well as during the weekend and public holidays it is lower.
