FAQ'S
We are a gas & boiler installation company. We specialise in gas, heating & hot water services. Founded by two cousins in 2015. They wanted to change the industry by making it simple, hassle free & cost effective. They built the company on technology that enables them to offer great quality work at great prices.
All workmanship is covered by a Master Gas London 12 month guarantee. The guarantee is on all services we offer. A new boiler installation will come with it’s parts & labour warranty & the Master Gas London 12 month workmanship warranty. If there is any problem with our work, we will send one of our in house engineers to rectify the issue.
At Master Gas London we DO NOT use subcontractors. We have our own in house engineers with our own vehicles. All our competitors are trying to reduce costs by subcontracting all works to any engineer with his own van. Quality work is what the founders of Master Gas London have built the company on. Subcontracting is not the way if you’re looking for quality work.
A like for like installation will take one day to complete. A conversion from a gravity system to a combi will take two days.

All boiler installations come with a boiler & flue kit, magnetic system filter, limescale reducer which others will charge an extra £65 for, a wireless or smart thermostat, materials required & a magnacleanse flush which our competitors will charge up to £300 for.
