Commercial Boilers, Heating & Hot Water
Commercial Boiler Service
A boiler that fails in January doesn’t just cost a repair. It closes a school, empties a hotel, or leaves a care home running on portable heaters, usually in the coldest week of the year.
Robinsons Facilities Services maintains commercial boiler plant across Yorkshire and the Humber with our own Gas Safe registered engineers holding commercial categories. Servicing is documented on a CP17 gas installation safety report. This covers the gas installation and every appliance on it, and is the document your insurer and your auditor will ask for.
- Annual servicing from £250+VAT per boiler
- Annual gas safety certificate included
- Contracts from £385+VAT/year

A commercial boiler service is an annual safety and performance inspection carried out by a Gas Safe registered engineer holding non-domestic categories. It covers combustion analysis, gas tightness, flue integrity, ventilation and controls, and is recorded on a CP17 gas installation safety report covering the whole installation. Domestic Gas Safe registration does not cover commercial appliances.
What the law actually requires
Most providers will tell you an annual commercial gas safety inspection is a legal requirement. That is not quite right, and the distinction is worth understanding because it changes what you are actually exposed to.
The Gas Safety (Installation and Use) Regulations 1998 require gas appliances and pipework to be maintained in a safe condition, and require all gas work to be carried out by a Gas Safe registered engineer. Those duties are hard law. What the regulations do not do is name a CP17 or set a twelve-month interval for owner-occupiers the way the domestic landlord regime does.
So the annual cycle comes from somewhere else: it is what insurers require, what auditors expect, and what makes the safe-condition duty demonstrable. Without a current report you are relying on an assertion rather than evidence, and a gas incident with no maintenance record is where prosecutions and refused claims both start.
Our article on what happens if you don’t service your boiler covers the operational side of that.
What a commercial boiler service includes
A service is a defined sequence of tests, not a visual check and a sticker. On every appliance our engineers carry out:
- Combustion analysis: flue gas readings taken and compared against the manufacturer specification, which is where efficiency loss and incomplete combustion show up first.
- Gas tightness testing: the installation pressure tested to confirm there is no leakage on pipework or fittings.
- Flue and ventilation checks: flue integrity, termination and spillage, plus confirmation that the plant room has adequate air supply.
- Burner and heat exchanger inspection: cleaning, condition assessment and adjustment.
- Safety device testing: flame supervision, overheat and pressure protection, and gas valve operation.
- Controls and calibration: thermostats, time clocks, interlocks and sequencing checked against how the building actually runs.
- Documentation: the CP17 report issued, with any defect classified and the responsible person notified.
Where a service finds a fault, it is reported and quoted rather than fixed on the spot without agreement. Corrective work is handled through commercial boiler repair.
Boilers and manufacturers we service
Our engineers service commercial gas, LPG, oil and electric boilers, from small wall-hung units in an office to multi-boiler cascade systems and plant room installations. Common manufacturers include Worcester Bosch, Vaillant, Ideal, Potterton, Remeha, Hamworthy and Strebel.
Burner servicing on pressure-jet and modulating burners is covered separately under boiler burner maintenance. Gas catering appliances are not covered by a CP17 and need a CP42 issued by a catering gas engineer, which sits under commercial catering maintenance.
Our guide to the lifespan of a commercial boiler sets out typical service life by boiler type, which is worth knowing before booking a service on ageing plant.
Pricing
Servicing is priced per boiler, because the appliance is the unit of work rather than the visit. Sites with several boilers are quoted together, which brings the per-boiler rate down against booking each one separately.
Annual service: from £250+VAT per boiler
A full service to the manufacturer specification, carried out by an engineer holding commercial Gas Safe categories, with the CP17 issued on completion.

Maintenance contract: from £385+VAT a year
Servicing scheduled and tracked across the boiler plant alongside your other statutory items, with certification held on file, priority response, and preferential rates on any remedial work. Most multi-boiler and multi-site clients move to a contract because the risk stops being cost and becomes a missed renewal date.
How we support you
Boiler work is delivered by our own engineers rather than subcontracted, which is why the Gas Safe registration sits with us rather than with a supplier. Robinsons Facilities Services has worked on commercial boiler plant from Harrogate since the 1960s, across schools, care homes, hotels, churches, museums and industrial sites.
Robinsons Facilities Services is Gas Safe registered (552076), OFTEC registered for oil-fired plant, SafeContractor approved, and holds UKAS-certified ISO 9001. Boiler servicing sits within our wider commercial heating work, and where a boiler is beyond economic service we can quote replacement and installation rather than leaving you to find someone else.
Contract customers also have access to our 24/7/365 out-of-hours call-out facility. This is a separate service, available to PPM contract customers only.

Boiler Service and Repair FAQs
Servicing starts from £250+VAT per boiler with the CP17 included, and maintenance contracts start from £385+VAT a year. Boiler type, plant room access and the number of appliances on site are the variables. Send us an enquiry or call us on 01423 226578 for a price against your appliance list.
A CP17 is the non-domestic gas installation safety report, the commercial equivalent of the domestic CP12. It records the condition of the gas meter and emergency control valve, the pipework and tightness test, each appliance assessment, flue condition and ventilation adequacy, and classifies any defect found. It is the document insurers, managing agents and enforcing authorities ask to see.
The safety duty is legal; the certificate and the twelve-month interval are not named anywhere in the regulations. In practice the distinction rarely helps you, because insurance policies and audits are written around annual inspection, and after an incident the question is what evidence you hold rather than what the statute said.
Annually as a minimum, and the manufacturer warranty usually depends on it. Plant working hard, running continuously, or serving a critical use such as a care home or a production process is often better on a six-monthly cycle. Boilers on a heating-only load are best serviced in summer, when availability is easier and a fault surfaces in July rather than during the first cold snap.
No. Commercial appliances require Gas Safe registration in non-domestic categories, which are separate qualifications from domestic. A certificate issued by an engineer without them does not demonstrate compliance and will not satisfy an insurer. You can check any engineer or business on the Gas Safe Register.
It is classified, recorded on the CP17 and explained to you. An appliance assessed as immediately dangerous will be disconnected with your permission and a warning notice issued, because leaving it in use is not an option available to a registered engineer. Less serious defects are reported with a quote so you can decide the timing.
Yes, all four fuel types are covered. Oil-fired plant is serviced under our OFTEC registration rather than Gas Safe, and LPG appliances require their own Gas Safe category, which our commercial engineers hold. Send us an enquiry or call us on 01423 226578 to confirm cover for your plant.
