Definitely worth every one of the 5 stars that I have given this company. A breath of fresh air! Clean, polite, tidy, hard working and above all the quality of the workmanship is second to none. This company definitely deserve to be called A1 Builders. Thanks for a great job on my rebuild.

I have used Keith and his team at A1 complete for many jobs at my businesses. I feel that Keith is a very genuine and helpful proprietor. The builders made it easy for me to undetestand what work needed to be carried out, why it needed to be carried out and without any corners being cut. I also felt that relative to the quality of work (second to none) the prices of A1 complete are always fair and accurate. A brilliant local building company proving a great service to customers. Will definately use again and recomend to friends.

We are very happy with the service received from A1 Complete Builders. They are polite, punctual, hard working and always clean up after themselves. The standard of work was exceptional and the best thing was that the quote we were given was the price we paid - now that doesn't happen very often! Thanks Keith, great Job I thoroughly recommend you and your team to anyone needing some building work, large or small.
