Awful customer service. Was referred to them though the affordable warmth scheme in 2016. Had a survey of the house done and electricians come out to measure up to replace storage heaters then complete radio silence. They promise to write and call you with updates but don’t deliver. Have lost count how many times they have said they “will look into it and call you back” to then never hear a thing. Final straw is 6 months after being told the job was being costed up I ring to check what is going on to be told the funding has been withdrawn and they were no longer installing them for me, and hadn’t even had the decency to notify me. My advice is avoid them at all costs!
