Customer Service
We have used this plumber for over 10 years. He has carried out work ranging from the installation of a new boiler, boiler servicing, radiator and boiler repairs and most recently fixing a leaking pipe valve. He is reliable, friendly and provides a good service and sound advice, and his pricing is reasonable. We would highly recommend his services.
