You receive a transparent, no‑surprises quote and timescale — and a breakdown of access, tank work and any civils required before we book the install.
Install, test & handover
We fit the boiler, commission to OFTEC standards, test the system and provide safety certificates, controls setup and operator instructions at handover.
