Our Values
What Drives Us
Safety & Compliance
All gas work is carried out by Gas Safe registered engineers and covered by public liability insurance. Every installation and repair follows current regulations and manufacturer guidelines for safe, compliant heating systems.
Two Decades of Practical Experience
Over 24 years in the trade means we know boilers and central heating systems inside out — from Combi boilers to unvented cylinders and LPG work. Practical experience reduces call-backs and speeds up fault diagnosis.
Local & Responsive
Based in Penperlleni and working across Monmouthshire, Abergavenny, Monmouth and Newport, we offer quick callouts and direct contact with the engineers who do the work. Local knowledge of typical Gwent housebuilding and plumbing layouts keeps jobs efficient.
Tidy, Trade-Standard Workmanship
We treat homes with respect — neat pipework, careful flue routing and clean site finish are standard. Installations are completed to manufacturer requirements whether it’s Worcester Bosch, Vaillant or specialist kit like air source heat pumps.
Clear, Friendly Communication
Customers get plain, jargon-free explanations of faults, options and next steps. Appointments arrive on time and engineers leave a tidy, safe working area with any questions answered before they go.
Aftercare & Confidence
Every installation comes with a 12-month workmanship guarantee and ongoing servicing options to prolong boiler life and maintain efficiency. We stand behind our work and make follow-up straightforward.
