Plain-English breakdown, so you know exactly what you're paying for, and why it matters before we set foot on site. ### What it is Commercial gas and heating services across Hertfordshire, Buckinghamshire, Berkshire, Surrey and London: plant room servicing, warm air heater installation and maintenance, commercial boiler installs (up to 1MW cascade), gas tightness testing, purging and recommissioning, landlord and statutory compliance. ### Who it's for Facilities managers, school estates teams, multi-site retail operators, restaurants and pubs, light industrial units, care homes, and commercial landlords needing a single Gas Safe contractor across the portfolio. ### When you need it Annual service schedules due, plant room equipment past its design life, repeated boiler lockouts, new tenancy fit-outs, statutory compliance audits, or when your incumbent contractor is no longer reliable on response times. ### Why it matters Commercial gas is a different qualification stack to domestic, COCN1, ICPN1, CIGA1, TPCP1A, and the consequences of an under-qualified engineer touching a 200kW cascade or a public-occupancy warm air heater are severe (HSE notices, lost insurance, closed premises). A properly ticketed contractor with documented RAMS is non-negotiable. The cost of doing nothing ## What goes wrong when this is ignored. Commercial heating failures cost in operating hours, not just repair bills. ### Risks of waiting - An uncertified commercial gas job invalidates your buildings insurance, full stop. - A plant room lockout during a winter cold snap can shut a school or care home in hours. - Failed statutory testing means a Gas Safe Improvement Notice, public record, and a clock on remediation. - Warm air heaters running outside combustion tolerance vent CO into occupied spaces, a criminal liability issue. ### Common mistakes - Using a domestic Gas Safe engineer on a commercial appliance, the qualification (and the insurance) doesn't cover it. - Skipping the annual service to save budget, repair bills always exceed the saving by year two. - No documented RAMS on site, first thing a Health & Safety auditor or insurance loss adjuster asks for. - Booking the cheapest tender without checking ACS qualifications, most cheap commercial bids are domestic engineers stretching scope. Our process ## How the job actually runs. Same system every time. No improvising on your floor. 1. 01 ### Site survey & asset register We visit, photograph, model-and-serial every appliance, log existing service history and build you a digital asset register. 2. 02 ### Scope & scheduled quote Fixed-fee annual service contract or one-off works quote, with RAMS, insurance certificates and ACS tickets attached. 3. 03 ### Out-of-hours mobilisation We schedule plant work around your operating hours, evenings, weekends, school holidays, at no premium for contracted clients. 4. 04 ### Work & live documentation All work logged on a tablet on site, photos uploaded, gas tightness and combustion analyser readings recorded, sign-off in writing. 5. 05 ### Certificates & portal access Certificates, service reports and asset history all available on a secure client portal, ready for insurance audits and FM inspections. What you get ## The outcomes that matter. ### Single contractor, full portfolio One number for every site, schools, branches, units. Consistent service standards across all. ### Compliant by default Every job comes with RAMS, ACS tickets, insurance and certificates. Audit-ready, always. ### Scheduled around you Work during shutdown periods, school holidays, weekends or out-of-hours, no operational disruption. ### Same-engineer continuity You get the same lead engineer on your sites repeatedly, they learn your plant and your processes. ### Asset register digitised Every appliance logged with model, serial, last service date and warranty status. Visible on your portal 24/7. ### Statutory compliance handled CP15/16/17 commercial gas safety records issued and renewed on schedule. Nothing falls through. In depth ## Everything worth knowing before you book. The details a salesperson skips. Skim it, or read every word, both are useful. Questions on this? Talk to a Gas Safe engineer direct.

Annual major service plus interim mid-year inspection on contracted clients. ### Warm air heaters, Powrmatic, Reznor, Combat Direct-fired and indirect-fired warm air heaters in warehouses, workshops, MOT bays, garden centres and industrial units. We service, repair and replace burners, fans, motors, flame failure devices and gas valves on all major brands. Annual statutory service includes combustion analysis, gas pressure check, flue integrity test and CO check in occupied zone. ### Commercial gas testing and purging (CITPC1 / TPCP1A) New installs, alterations and meter swaps all require statutory tightness testing and purging to IGE/UP/1 (above 35mm) or IGE/UP/1B (small-bore). We hold the current ACS qualifications, log every test electronically, and issue certificates with witness records. ### Sectors we work in across Hertfordshire, Buckinghamshire, Berkshire, Surrey and London Independent schools (term-time and holiday scheduling), retail multiples (after-hours mobilisation), pubs and restaurants (kitchen gas equipment, interlock systems, CIGA1), care homes and supported living (sensitive scheduling, no resident disruption), light industrial (warm air, process gas), commercial landlords with mixed-use portfolios. ### Reactive call-out and breakdown cover Contracted clients get a guaranteed response window (typically 4 hours in core hours, 8 hours out-of-hours) on plant breakdowns. We carry common cascade controls, gas valves and PCBs on the van so most fixes are first-visit. General work gallery ## Recent Heatrite jobs that show the standard of our work.
