Best Gas installed a new bathroom, replacing the boiler and putting in a shower rather than a bath. They were punctual, helpful and obliging and Minar, who runs the firm, went out of his way to communicate and to check that everything was up to standard, I cannot recommend this firm too highly.

Used Best Gas' services to fix a boiler installation performed by another installer. The work was scheduled and performed promptly and to a high standard. Minar and his team were professional, friendly, communicated well and offered good advice and aftercare. Highly recommended.

Best Gas installed a new Smart thermostat for my Gas central heating. Arrived on time, carried out the work promptly and efficiently without any fuss. Highly knowledgable and professional. Courteous but friendly and approachable. I will definitely use them again. Recommended without any reservations.

Minar has been great and very patient with my milion questions. The problem with my immersion heater was fixed in two visits (first to diagnose the issue, second to replace faulty elements). Very reliable. I wholeheartedly recommend.

I can't recommend Minar and the Best Gas team more highly. Their communication was clear, and they did what they said. What was a messy scramble of pipework is now organised and pristine - and they even set up my Hive system too. Very happy

Minar and his team did a stellar job. On top, they communicate clearly and fast. It’s not easy to find a reliable engineer, but Minar and team rock it! Admin was also clear and on point.

The appointment was easy to arrange. The boiler service was carried out quickly and efficiently and the certificate was provided by email. I would highly recommend this company.
