Great Installation, Superb After Sales Service
We used Grant Store for the installation of solar panels some 3 years ago now. The installation was great but what has been amazing is the after sales service. We had a problem when our home router was changed by BT but help was on hand to reprogram the system, and when the bird netting failed this summer, it was replaced quickly, efficiently and at no cost to us. Customer Service response is fantastic. We would highly recommend them.

We’re delighted to hear that your solar panel installation has continued to serve you well over the past three years. It’s especially rewarding to know that our after-sales support has made a meaningful difference — from assisting with reprogramming after your router change to promptly replacing the bird netting at no cost.
Our team is committed to being there for our customers long after installation day, and your experience is exactly what we strive for. Your kind words about our customer service mean a great deal to us.

Central Heating Installation
From the moment of the first phone call to the completion of the installation I found all involved very professional and helpful. I can't tell you what a difference to my life the central heating will make. Having rheumatoid arthritis being cold affected me alot. Big thanks to Elliot and Saul for all their hard work.
