Our Gas Safe engineers conduct full system surveys to recommend optimal boiler types, including combi, system, and regular models. All installations qualify for extended manufacturer guarantees up to 12 years when applicable.

We provide CP12 gas safety certificates for landlords, ensuring compliance with legal requirements. Our engineers inspect all gas appliances and installations annually, maintaining safety standards and legal compliance for rental properties across Hertfordshire.

Our powerflushing service removes sludge and debris from central heating systems using magnetic filtration. This process improves system efficiency, reduces noise, and extends boiler lifespan by eliminating circulation issues caused by accumulated residue.
