I was not told in advance how complicated it would be, with specific requirements for the fuse box which 8 was told I would need to get a separate electrician at my own expense to fit. The fitter was very helpful when he arrived but was 2 hrs late and was sent by the office to a wrong address 20 minutes away. The installation took nearly 3 hrs so didn’t end until nearly 6 and I was trying to listen to explanations while making the kids’ tea. No criticism of the fitter - rather of the misleading expectations we were given about the speed and simplicity of the process.
