I initially used Marks Electrical as they had the product I wanted in stock. It was slightly more expensive than a couple of other suppliers but they couldn't deliver for weeks. After using them I can say I will happily pay a bit extra in future and buy from them. The order was handled swiftly and I was kept up to date at all times. I ordered on a Friday night and it was delivered Tuesday. I got a 2 hour time slot that morning and later a message about half an hour before delivery. The delivery drivers were both great too. Very helpful and friendly. I could also pay to get my old machine taken away which was very useful.
