What Drives Us

Worcester Bosch Accredited Installer

Official Worcester accreditation means deep product knowledge, direct access to manufacturer support and the ability to register long manufacturer warranties on new boilers. That accreditation helps keep installations compliant and warranty-ready.

Manufacturer-Backed Boiler Warranties

Offerings include long, manufacturer-backed boiler warranties — ensuring homeowners retain full cover when installations meet manufacturer requirements — plus a standard 12-month workmanship guarantee for added peace of mind.

Gas Safe Registered and Fully Insured

Gas Safe registration and £2 million public liability cover mean every job is certified and insured. Safety, correct gas work and professional documentation are standard on every service and installation.

Local, Personal Service

Based in South Wales and serving Aberdare, Merthyr Tydfil, Mounty Prees and Cardiff, the business prioritises fast, same-day responses for non-emergency callouts and prompt, face-to-face quotes for homeowners.

More Than 13 Years’ Experience

Operating since 2013 and installing around 70–80 boilers a year, Daniel brings hands-on experience across domestic systems, controls and heat optimisation — ideal for traditional Welsh terraces, semis and modern new builds.
