Message: ‘Great experience from quote to installation… We were given helpful advice on the most appropriate appliance that would meet our needs. We required the flue to be relocated and were delighted that this could be carried out with the installation of the boiler. The installation team were on time, polite and very considerate. We were kept informed throughout the process… I would definitely recommend them.’

The work was also able to be carried out promptly and was installed to a very good standard. I also like the appropriate use of technology for appointments, invoicing and payments. Very happy with the overall service.’
