I applied for a non repayable grant from Energy Grant Solutions to update my electric Economy 7 heating and cavity wall insulation some months ago and since having the cavity wall insulation replaced and the 4 old 3kw Dimplex Economy 7 heaters replaced with the more modern Dimplex Quantum ones. I know I have been saving money on my electric bills as the new ones are bigger panels but with lower KW/perHour input with internal fans to boost the heat when needed later in the evening. I only got to use them for a couple of months at the end of last winter by the time they were fitted but I could definitely feel the difference, as well as see the difference in electric night bills. I am very happy with everything this company has done for me with organising all this. It does take some time to get everything surveyed by different trades and organise the fitting but all tradespeople were great to deal with from making appointments and arriving on time and leaving no mess! I am so pleased that I applied and very grateful that a grant was available for my circumstances. I would recommend this company to anyone looking to update with an old for new grant.
