About GasInsider

GasInsider is a free resource for UK gas engineers: trainees, experienced engineers and heating businesses.

We answer the questions that come up on the job and in the van: what the gas safety regs actually ask of you, how to price a boiler swap, why a boiler keeps locking out, how to get qualified and registered, and how to take some of the paperwork off your hands.

What you'll find here

• Regs and safety: the gas safety regulations, landlord records, unsafe situations and registration, in plain English.
• Boilers and heating: installs, controls, system design and heat pumps.
• Fault finding and trade tips for real jobs.
• Pricing and business: quoting, getting paid, going self-employed and insurance.
• Training and careers: routes in, ACS assessments and registration.
• AI and admin: tools that cut the time spent on quotes, certs and invoices.
