Building-services support that respects occupied environments, vulnerable people and the need for dependable, well-documented building systems.
Care homes, supported-living schemes, clinics and other healthcare settings rely on building systems that work quietly in the background. Hot water, space heating, ventilation, electrical infrastructure, kitchens and plant rooms all affect comfort, hygiene, safeguarding and day-to-day care. Established in 2019 and based in Farnham, ComGas Services UK Ltd is a Building Services Contractor working across Surrey and the surrounding southern counties on commercial and domestic buildings.
Our work can cover commercial gas, heating and boilers, plumbing and pipework, mechanical services, electrical installation, HVAC, air conditioning, building management systems and planned maintenance. We can also support water heaters, plant rooms, gas testing, tightness testing, purging and decommissioning, commercial catering gas, temporary heating, renewables, heat pumps and oil. The scope depends on the building, systems, occupancy and client responsibilities.
Use one coordinated brief where several disciplines meet, or commission a focused survey for a particular system. Each service is scoped to the property and its operating requirements.
Inspection, installation, repair and improvement support for commercial gas appliances, boilers, heating distribution and associated plant, with gas safety and access considerations built into the scope.

Learn more about Boiler and plant-room worksCommercial plumbing, pipework, water heaters and service alterations for occupied buildings, with planned isolation and reinstatement arrangements agreed before work starts.

Learn more about Electrical systemsHVAC, air conditioning and building-controls support to improve control, comfort and visibility of plant operation, subject to the site’s clinical and environmental requirements.
Learn more about HVAC, cooling and BMSPPM and maintenance-contract support for recurring checks, asset schedules, defects and planned remedial work. Contract terms, exclusions and response arrangements are agreed rather than assumed.

Plan intrusive work around care routines, appointments, medication rounds, quiet periods and safeguarding arrangements. Temporary heating or hot-water measures may need to be considered where an outage cannot be avoided, subject to the site plan and equipment suitability.
Identify calorifiers, water heaters, secondary circulation, outlets and vulnerable points. Agree isolation, temperature, flushing and reinstatement arrangements with the responsible person; specialist water-hygiene duties remain with the client and their appointed advisers.
Review boiler rooms, pumps, pressurisation, controls, flues, gas trains and electrical supplies as a system. Check routes, lifting constraints, fire compartments and safe access before proposing replacement or upgrade work.
Consider air movement, extract, filtration, cooling, humidity and comfort in relation to the room use. HVAC or air-conditioning changes should be coordinated with infection-control, estates and clinical requirements where they apply.
A useful maintenance record should identify assets, tests, defects, isolation points and follow-up responsibilities. Keep statutory and operational records with manufacturer information and commissioning data.
Agree permits, escorts, DBS or site access rules where required, resident communication, tools and materials control, dust/noise precautions and emergency contacts. A competent contractor supports the site’s arrangements but does not replace the client’s risk assessment or responsible-person duties.
Good preparation reduces disruption and gives the contractor enough information to plan a safe, proportionate response. Include the following wherever known.
Explain whether the site is a care home, clinic, supported living building, treatment area, office or mixed-use property, and identify rooms that cannot be entered without an escort or specific control.
Share plant schedules, previous service reports, gas records, water-hygiene information, controls details, drawings, warranties and known defects. Gaps can be identified during survey rather than hidden in a quotation.
Set out acceptable shutdown windows, welfare arrangements, access routes, parking, deliveries, infection-control measures, fire-alarm interfaces and who can authorise isolation or return to service.
Agree who briefs occupants, how noisy or dusty work is segregated and what happens if an asset fails or a defect is found. Contractor RAMS should align with, not replace, the client’s arrangements.
Request the records needed by the estates team: test certificates where applicable, asset labels, commissioning information, operating instructions, outstanding defects and recommended next actions.
Consider accessibility, spare-part availability, controls, energy use, plant redundancy and planned replacement at the design stage. A cheaper installation can be unsuitable if it makes future safe maintenance difficult.
Care and healthcare clients often have overlapping duties under health and safety, gas safety, fire safety, water hygiene, electrical safety and building-management arrangements. HSE guidance on managing health and safety, gas work and legionella is useful context, while CQC requirements and NHS technical guidance may apply according to the provider, service and building. ComGas can deliver agreed engineering work and provide relevant records.
Our credentials include Gas Safe Registration, OFTEC Registration and REFCOM F-Gas Certification, alongside CHAS Accreditation, Constructionline Approval, Commercial and Domestic ACS, OFTEC Engineers, Heat Pump Qualifications, WRAS/Water Regulations, Commercial Pipework, Commercial Catering and Commercial Testing & Purging credentials. Credentials are relevant to the work commissioned and should be matched to the specific appliance, system and task. We do not present a contractor credential as a substitute for the client’s statutory management system or specialist clinical advice. All our engineers and staff who attend schools and care homes hold enhanced DBS checks.
For planned works, we can help define access, isolations, testing, commissioning, documentation and remedial priorities.
Need an answer for a specific site? Send us the address, building use and systems involved.
Contact ComGasYes, subject to the site’s access, safeguarding, infection-control and risk-management arrangements. We agree the work area, shutdowns, escorts and communication plan with the client before attendance.
We can scope these disciplines together where the capability and site requirements fit. The proposal should identify assets, frequency, exclusions, specialist responsibilities and the records to be provided.
Our work can include relevant plumbing, hot-water and plant support, but a water-hygiene risk assessment and responsible-person arrangements must be confirmed with the client and any appointed specialist adviser.
Temporary boiler or heating support can be considered where technically and operationally suitable. It is subject to site access, fuel, distribution, safety controls, duration and engineer availability.
Provide the building use, location, asset list, previous reports, known defects, access and shutdown constraints, drawings or photographs, required dates and the client contact who can authorise isolations and works.
ComGas holds the approved credentials listed on this page, including Gas Safe Registration and Commercial ACS. The exact qualification and authorisation should be matched to the appliance and task in the agreed scope.
