Superb. very pleased with everything.

Sustain installed an air source heat pump and solar panels with battery. They were very pleasant and worked quickly and efficiently, explaining the process as they went along. Communication was good from start to finish; they answered all my queries, explaining so I could understand. They sorted out some plumbing problems left by the previous owners of the house and left everything safe and tidy at the end. We are very pleased with the installation.

Very happy with their work of all of their team . Very thorough and really helpful. Would definitely recommend.

Efficient, professional service and will engage for future services of air source heat pump.

From the initial telephone contact to book a service of our existing 12 year old heat pump installation through the subsequent energy survey, technical design, installation walk through, the installation of a replacement Heat Pump and finally commissioning and handover. The Sustain team were exemplary in their behaviour and performance at all stages of the project.

I cannot praise too highly the professionalism of Sustain from start to finish of our heating project. Ours is a 1840 townhouse, five storeys, listed grade 2*, in a conservation area. Sustain commissioned an independent heating survey and built up the specifications for the project in order to meet our requirements for heating. There was an unfortunate 5-month delay while we obtained planning consent from the city council, and then we agreed with Sustain on a start date in the spring. Sustain completed the whole work as promised in eight working days; we are very pleased with the result.
