Our Certifications and Registrations

Every job we carry out is backed by the appropriate legal certification. Here is what each one means for you.

✓ Gas Safe Registered

Gas Safe registration is the only legal qualification that permits an engineer to work on gas appliances in the UK. All domestic and commercial gas work — including boiler installation, repair, servicing, and landlord gas safety inspections — must be carried out by a Gas Safe Registered engineer. You can verify our registration at GasSafeRegister.co.uk.

⚡ 18th Edition (BS 7671)

The 18th Edition of the IET Wiring Regulations (BS 7671) is the current standard governing all electrical installation work in the UK. Our electrician Matt is fully certified to the 18th Edition, ensuring that every consumer unit replacement, rewire, and electrical installation meets the latest safety requirements and is fully compliant with UK law.

💧 G3 Unvented Cylinder Certified

Working on unvented hot water systems is a notifiable activity under UK Building Regulations. A G3 certification is the legal requirement that authorises an engineer to install, commission, and service unvented hot water cylinders. Ralf holds this certification, covering installation of systems such as the Range Tribune HE for residential properties across London.

What Our Customers Say About Us

★★★★★

“I recently had my boiler replaced and couldn’t be happier with the service from this gas and heating company. From start to finish, they were reliable, efficient, and incredibly easy to communicate with. Every step was clearly explained, and the team arrived exactly when they said they would. A special mention goes to Rina, who was absolutely fantastic throughout the entire process. Her communication was prompt and friendly, and she made sure I always knew what was happening and what to expect. Her professionalism and attention to detail really stood out. The installation itself was completed to a high standard, with everything left clean and tidy. My new boiler is running perfectly, and the whole experience was stress-free. I highly recommend them to anyone looking for trustworthy, high-quality heating work.”
