What Our Clients Say About Us

Real reviews from real customers across London.
James W.Boiler Installation
GL Gas installed our new boiler quickly and professionally. The engineer arrived on time, explained every step of the installation, and left everything spotless. The heating has been working perfectly ever since. I highly recommend them to anyone looking for a reliable Gas Safe engineer in London.
Sarah M.Gas Safety Certificate
We needed a Gas Safety Certificate for our rental property at short notice, and GL Gas fitted us in the very next day. The whole process was straightforward, the engineer was friendly and knowledgeable, and the certificate was issued immediately after the inspection. Excellent service from start to finish.
David R.Boiler Repair
Our boiler stopped working on a cold evening, and GL Gas responded much faster than we expected. The fault was diagnosed quickly, the repair was completed during the same visit, and the pricing was fair with no hidden charges. It's great to find a company that's honest, professional, and genuinely cares about its customers.
