Services
Boiler Replacements
We install high-efficiency Vaillant boilers with 10-year warranties, ensuring reliable heating for modern homes. Our Gas Safe engineers assess your property's needs to recommend optimal boiler types, including combination, system, or heat-only models. Backed by manufacturer certifications and industry-leading guarantees, our installations prioritise energy efficiency and long-term performance.
Gas Safety Checks
Our Gas Safe engineers conduct thorough safety inspections for rental properties, identifying gas appliance risks and issuing official CP12 certificates. This service ensures compliance with legal requirements while safeguarding tenants from carbon monoxide exposure and other hazards associated with faulty gas systems.
Underfloor Heating
We design and install water-based underfloor heating systems using JG Speedfit technology, offering even heat distribution and energy savings. Our solutions integrate with existing central heating and include smart control options via the JG Aura app for remote temperature management.
Power Flushing
This process removes sludge and debris from central heating systems using high-velocity water flow and chemical treatments. Recommended before boiler replacements, it restores system efficiency, reduces noise, and extends equipment lifespan while preventing future blockages in modern high-efficiency boilers.
Emergency Repairs
Available 24/7 for urgent heating failures, our rapid-response service addresses boiler malfunctions, leaks, and gas safety issues. We prioritise same-day call-outs across Southampton, using fully equipped vehicles to resolve most problems during the initial visit without requiring multiple appointments.
