About 123-Gas

Edinburgh's gas & heating specialists

Gas Safe registered engineers looking after boilers and heating for homeowners and landlords across Edinburgh and the Lothians.

Who we are

123-Gas Edinburgh is a Gas Safe registered plumbing and heating company covering Edinburgh, Midlothian & the Lothians. We handle everything from routine boiler servicing to full installations and urgent repairs, for homeowners and landlords alike — and we’d rather earn repeat business through reliable work than chase every job going.

How we work

Every engineer on the van is on the Gas Safe Register. Every job gets a fixed written price before we start, and every new boiler is registered for its manufacturer warranty on the day.
