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.

We asked Minar to install a new boiler and new central heating panels. He gave us a breakdown of all costs involved and the work timescale. Minar and his team worked conscientiously and fulfilled their deadline. We are happy with the results.

A Superb Company

I used the services of Best Gas Ltd. for many years. They never fail to impress me. The latest job was to fix a leaking pipe in a very inaccessible area. They contacted the tenant, arranged a suitable date and time which was within days of me reporting it to them, accessed the offending pipe, replaced it, sent me photos and left the property in a clean and professional manner. Best Gas Ltd. is hyper professional, prompt and courteous. I highly recommend them to agents and fellow landlords.

I would highly recommend Best Gas. They have done numerous jobs for me, most recently replacing my old shower valve which was not straight forward and involved adjusting pipework. Minar coordinated the whole job, scheduling tile removal, first fix, retiling and final fitting and testing of the new valve. Everything ran to schedule and the job was completed quickly and efficiently to minimise inconvenience. A great service all round.

Keston dual flue combi gas boiler replacement

Minar is a real gem and an expert in his field. Most companies that I contacted about replacing my boiler either had no clue about this system, or were quoting extortionate rates for a poor service, that would have involved costly repairs to the ceilings. The first time I spoke with Minar I felt immediately at ease. He thoroughly explained my options, offering effective solutions with minimal disruption. He and his team worked extremely efficiently at the agreed time, and everything is finished to a high standard, with fair and transparent pricing from the start. If you are looking for a knowledgeable, reliable and honest plumber, Minar is your man and I wholeheartedly recommend Best Gas London

Vaillant annual boiler service

I used Vaillant info to find 3 local gas-safe, Vaillant-accredited plumbers who might do my obligatory annual service. Minar from Best Gas is very local, and was professional on the phone. He and his colleague were prompt, pleasant, courteous, quiet and tidy. They got on with the job and explained what had been done, as well as quickly fixing a rad that hadn't worked properly for a year, which is great. Comms had been good throughout. I will use Best Gas again and have already recommended them to a neighbour.

Minar and colleagues conducted a service and control board replacement for a gas boiler. They were professional, friendly and tidy. Advice was clear and concise. Pricing transparent and fair. In this case the issues with the control board were not known when they were booked; but when identified they acted quickly to ensure we had the repair completed the same day. Efficiently sourcing parts, and communicating clearly.
