We have had our boiler replaced recently replaced by Nigel at Beaumont Plumbing. Excellent service and very professional. Would recommend to everyone. We have had issues with our heating and radiators since we moved in 6 months ago but no one was able to fix. Very reasonable price. Since fitting us with a new boiler Nigel has kindly organised our roof to be repaired. The guys were so lovely and professional. I now have a sealed roof and warm house thanks to them. Definitely will use them again.
