Cable route required by first engineer was ridiculous (up through floorboards, wall and into loft, then across loft, out through soffits and down outside wall!) Fortunately some remedial work was needed before the installation could take place and our electrician simply ran the cable horizontally, a total length of 5m to get to the outside wall. Took him all of 30minutes. Much more experienced engineer attended at second visit, was more than happy at the route etc and completed the install without problem.Lovely guy, and a credit to the company. So very pleased with the outcome in the end!
