Fantastic service! Josh was extremely professional and courteous. We believed we had a real issue with our heating system but Josh explained the pressure had dropped and the radiators hadn't been bled in a long time - which was surprising as we have had another engineer out to look into the issue previously! He explained how we can do it ourselves at home and didn't charge us for the call out. We will definitely be choosing him for our boiler servicing and we're very impressed by the service. 10/10.
