Gillies did a fantastic job from when I first contacted them to enquire about renewables, through to installation and post-install support.
As a company they clearly understand the biomass market well, and their assistance in providing quotes and guidance was first-rate. Their workmen were friendly, professional and knowledgeable.
When I had a query about the wood pellet boiler, Gillies had a direct line to the manufacturer and got a quick response to questions.
Overall, highly recommended.
