Services
Boiler Installations
We install A-rated condensing boilers and combination systems tailored to your home's needs. Our engineers ensure efficient operation while complying with safety standards. Ideal for replacing outdated systems or new builds, our installations reduce energy costs and improve reliability.
Central Heating Repairs
Emergency and scheduled repairs for radiators, pumps, and thermostats keep your heating functional year-round. We diagnose issues swiftly to minimise downtime. Regular maintenance extends system lifespan and prevents costly failures.
Bathroom Upgrades
Full bathroom design, planning, and installation services transform your space. From cloakrooms to en-suites, we handle plumbing, tiling, and fixture fitting. Our approach balances aesthetics with practical functionality for modern, efficient bathrooms.
Powerflushing
Powerflushing removes sludge and debris from central heating systems, restoring efficiency. This process improves heat distribution, reduces energy bills, and prolongs boiler life. Recommended for systems showing cold spots or noisy pumps.
Underfloor Heating
We install underfloor heating systems that maximise space and energy efficiency. Suitable for new builds or retrofits, this greener alternative provides even heat distribution while reducing running costs compared to traditional radiators.
