Green Retreats' excellent and professional teams
Review By: Sabri Zain


I would like to personally thank the base installation, building and electrical teams for the excellent work they have done on my garden house. Their work was of the highest quality and the garden house I have now far exceeds any expectations I had when I first ordered it. The teams did their work with little, if any, disruption or damage to my property and left the site clean and tidy. The base installation and building teams led by Ian and Lee in particular had to handle some unpleasantness from a neighbour, which they did in a very professional and respectful manner.

My customer care administrator Rachel also did an excellent job helping to shepherd me through the process (despite the tardiness of my replies!)

Green Retreats have excellent teams working for them and I would have no hesitation at all in recommending them to friends and colleagues.
