The outfit seems professional enough and having had several firms out previously they seemed to know there facts. Installation happened quite quickly and you are asked to assess their work and tidiness on completion. My installation was done by what I believe to be an experienced electrician but not so experienced roofers. Having initially felt fairly happy in the cold light of day I found a tile was lifted and lots of rubbish blown all around the outside of my house. With the bad weather I cleared my gutter and also found fittings and a cigarette lighter. I complained about the tile and twice someone should have come out but no one has as yet, that was 5 week's ago. So in essence I cannot recommend them. If they do however actually rectify their shortfalls then I would have to say use them and change this assessment somewhat. Be really critical in their work and if it's dark tell them you are not happy to except their work.
