The whole process of installing a biomass boiler was complex, but Gillies made the experience as straight forward as possible. They were thorough and took as much time as I needed to ensure the job was done to my satisfaction. The quality of the finished product once installed is excellent. Highly recommended.

Fuss-free, quality installation. Pre-sales, installation team and after-sales service excellent.Thoroughly recommended.
