Services
Underfloor Heating
Our underfloor heating systems provide even warmth distribution through piped water networks beneath floors. Ideal for new builds and renovations, this energy-efficient solution integrates with heat pumps and boilers. Customers report significant comfort improvements and reduced energy bills while maintaining aesthetic room design.
Air Source Heat Pumps
We install air source heat pumps that extract warmth from ambient air to heat homes and water. These systems operate efficiently even in low temperatures, offering sustainable heating with minimal maintenance. Clients benefit from lower carbon emissions and reduced reliance on fossil fuels.
Biomass Boilers
Our biomass boiler installations utilise organic materials like wood pellets for heating. These systems suit properties without gas connections, providing cost-effective, eco-friendly alternatives. Customers appreciate the renewable energy benefits and potential RHI payments.
Solar PV Systems
We design and install photovoltaic systems that convert sunlight into electricity. These solutions reduce energy bills and carbon footprints while increasing property value. Clients benefit from tailored designs optimised for local sunlight conditions and energy needs.
Bathroom Fitting
Our expert plumbers deliver complete bathroom installations from design to finishing touches. We handle all aspects including waterproofing, wetrooms, and shower systems. Customers praise our attention to detail and ability to create functional, stylish spaces within budget.
