INDUSTRIAL & MANUFACTURING
Engineering services for industrial and manufacturing buildings
Engineering support for production environments where plant condition, safe isolation, process continuity and clear records matter.
A practical, evidence-led approach
Building services planned around your premises
Industrial and manufacturing premises bring together production equipment, process services, workshops, warehouses, offices, welfare areas and loading operations. Building-services work must be engineered around the production schedule and the consequences of isolating gas, water, heat, ventilation, power or controls. ComGas Services UK Ltd is a Farnham-based Building Services Contractor, established in 2019, serving commercial and domestic buildings across Surrey and the surrounding southern counties.
We also handle commercial gas, heating and boilers, plumbing and commercial pipework, mechanical and electrical services, HVAC, air conditioning, BMS, plant rooms, water heaters, commercial catering gas, temporary heating, renewables, heat pumps and oil. We also support gas testing, tightness testing, purging and decommissioning. Process design, specialist machinery responsibility and production controls must be identified separately so the engineering scope remains safe and clear.
Capabilities
Industrial building-services capability
We can support defined building-services packages and coordinate interfaces with the client’s production, engineering and health-and-safety teams. Specialist process systems should be identified in the enquiry.
Heating and boilers
Boiler, heating, pumps, controls and plant-room support for workshops, warehouses, production support areas and offices, planned around operational constraints.
Learn more about Heating and boilersCommercial pipework
Pipework and plumbing support for building utilities, welfare areas, hot water and identified mechanical interfaces, with materials and design responsibility confirmed in the scope.

Operational priorities
Industrial priorities that shape the work
A manufacturing brief needs more than an equipment list. It should explain the process, interfaces, isolation philosophy, site hazards and what a failure means to people, product, plant and delivery commitments.
Process continuity and shutdowns
Identify production windows, critical services, controlled shutdown and restart steps, clean-down requirements, shift patterns and contingency arrangements. Temporary heating may be considered for suitable spaces, but cannot guarantee process continuity.
Gas and combustion systems
Map gas meters, regulators, pipework, appliance trains, ventilation, flues, combustion equipment and emergency isolation. Alterations require clear responsibility for design, testing, purging, commissioning and return to service.
Process and utility pipework
Define the medium, pressure, temperature, materials, route, supports, valves, drains, insulation, hygiene requirements and interaction with machinery. Confirm where specialist process-pipework design or certification sits.
Ventilation, extraction and heat
Assess general ventilation, local exhaust, make-up air, process heat, dust or vapour concerns and worker comfort. The solution needs to reflect the hazard assessment and the actual production process, not just room volume.
Controls and fault visibility
BMS, plant controls, alarms and metering can improve visibility of boiler, HVAC and utility performance. Confirm the existing controls platform, network access, cybersecurity rules and who owns the control strategy.
Maintainability and spares
Provide safe access, isolation points, lifting routes, labels, service clearances and realistic spare-part planning. A system that cannot be maintained without disrupting production may create a larger operational risk than its initial cost suggests.
Prepare the brief
Information to provide for an industrial enquiry
The following details help separate building-services work from process engineering and allow a safer method and more realistic programme to be developed.
Site and process description
Describe production, storage, workshops, welfare, offices, shifts and critical processes. Mark hazardous areas, restricted zones, hygiene-controlled spaces, traffic routes and areas requiring permits or escorts.
Utilities and asset data
Provide drawings, P&IDs where relevant, appliance schedules, gas and electrical information, pressures, temperatures, controls details, service history and known defects. Identify information that still needs verification.
Isolation and restart plan
State who controls lock-off, permits, gas isolation, electrical isolation, process shutdown, restart and product release. Include the test or inspection required before the system returns to service.
Production and delivery constraints
List blackout dates, shift changes, clean-down periods, stock movement, delivery access, lifting capacity, noise or dust restrictions and the cost of an unplanned outage to help prioritise options.
Site hazards and controls
Share asbestos information, COSHH or DSEAR considerations, confined-space issues, work-at-height controls, hot-work requirements and contractor induction rules. The site risk assessment remains the client’s responsibility.
Handover and maintenance
Define asset labels, commissioning records, test certificates where applicable, operating instructions, spare parts, training, red-line drawings and the defect close-out process before work starts.
Competence and records
Safety-led industrial coordination
Industrial clients may need to coordinate duties under the Health and Safety at Work etc. Act, gas-safety requirements, PUWER, COSHH, DSEAR, pressure-systems rules, work-at-height controls, asbestos management and fire precautions, depending on the site and activity. HSE guidance is an important starting point, but it does not replace a site-specific assessment, competent process engineer, hazardous-area assessment or permit system. ComGas delivers the agreed building-services scope and interfaces with the client’s controls.
ComGas is Gas Safe Registered, OFTEC Registered and REFCOM F-Gas Certified, and also holds 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. The relevant credential must match the appliance, refrigerant, fuel, pipework or testing task; no blanket capability is implied for specialist production machinery or hazardous-area work.
For planned or urgent work, we can help define isolation, testing, commissioning, access and record requirements.

Contact ComGasCan ComGas work around production shifts?
We can plan agreed building-services work around production windows, access and isolation arrangements. The client must confirm shutdown, permit and restart authority.
Do you work on process pipework and machinery?
We can scope commercial pipework and building-services interfaces. Specialist process design, machinery, hazardous-area systems and production responsibility must be identified so the correct competent parties are involved.
Can you test or purge a gas installation?
Gas testing, tightness testing, purging and decommissioning support can be considered for an agreed scope. The appliance, pipework, pressure, isolation plan, testing standard and return-to-service responsibilities need to be established first.
Can you provide temporary heating during a shutdown?
Temporary boiler or heating support may be suitable for some building areas. It depends on load, fuel, distribution, ventilation, access, duration and safety controls and should not be treated as a guarantee for production continuity.
What should an industrial survey cover?
Provide the site and process description, utilities drawings, asset schedule, service records, gas and electrical details, controls information, isolation arrangements, hazards, access constraints and the operational cost of downtime.
Do you offer ongoing maintenance?
We can discuss PPM or maintenance-contract support for agreed assets and reporting. Frequencies, exclusions, response arrangements, specialist interfaces and remedial approval routes should be documented in the contract.
