ComGas coordinates mechanical and electrical building-services work for commercial clients across Surrey from our Farnham base. We can support maintenance, refurbishment and installation scopes involving heating, plumbing, HVAC, electrical services, controls and plant-room interfaces, with practical attention to isolation, access, commissioning and handover.
Building systems do not operate in separate boxes. A heating upgrade may require electrical supplies, pumps, controls, BMS points, ventilation changes and new pipework. An office refurbishment may combine lighting and power with HVAC, access constraints, fire-stopping and tenant communication. A mechanical or electrical package that is not coordinated can leave interfaces unclear, commissioning incomplete or maintenance teams without usable records. ComGas helps facilities managers, contractors, landlords and estates teams define those interfaces before work starts.
Our approved capability includes mechanical services, electrical services, HVAC, air conditioning, BMS, commercial heating, plumbing and planned maintenance. We are Gas Safe Registered, OFTEC Registered, REFCOM F-Gas Certified, CHAS Accredited and Constructionline Approved, with other technical qualifications used where relevant to the scope. Electrical work is specified against the installation, competence and certification required for the agreed scope.
Surrey projects can involve town-centre buildings, offices, education and care estates, mixed-use property, workshops, warehouses and managed business premises. Existing services may be undocumented, shared between tenants or routed through occupied areas. A coordinated survey should identify plant rooms, risers, distribution boards, isolators, ventilation routes, external units, controls panels, access hatches and responsibility boundaries before a price is treated as a complete building-services scope.
Refurbishment and maintenance also have a people and logistics dimension. Surrey County Council's roadworks information can help teams review delivery and access constraints, while the council's development-plan guidance provides local planning context for changes to buildings and land use. Neither source endorses ComGas or replaces a site's approvals. The project team should confirm landlord, planning, building-control, fire, asbestos, permit-to-work and principal-contractor responsibilities where applicable.
The value of an integrated approach is often clearest in the handover. A client may need electrical test results, commissioning sheets, control sequences, asset labels, updated drawings, O&M information and a maintenance schedule that reflects the installed system. Establishing that list at enquiry stage helps prevent a multi-trade project being declared complete while an interface or record remains outstanding.
We can support a defined trade package or help coordinate connected services. The scope should state what is included, what is excluded, who controls each interface and what evidence will be handed back.
Mechanical installation, alteration and maintenance support for heating, plumbing, pumps, pipework, ventilation and plant-room equipment, subject to survey and design requirements.

Learn more about BMS and controlsA practical package for plant rooms involving boilers, pumps, pipework, valves, electrical supplies, ventilation, access and service clearances, with interfaces made explicit.

Learn more about Planned maintenance and FM supportStart with the building outcome and the interfaces, not just a list of equipment. Clear information helps separate survey work, design responsibility, installation, commissioning and ongoing maintenance.
State whether the requirement is maintenance, a refurbishment, a fit-out, a replacement or a new installation. Identify landlord, tenant, principal-contractor and specialist-designer responsibilities and list known exclusions.
Provide floor plans, schematics, single-line diagrams, panel schedules, plant lists, O&M manuals, controls information, service history and photographs. Mark unknown or inaccessible areas rather than assuming they are clear.
Identify electrical, gas, water, heating and ventilation isolations, permit-to-work rules, lock-off arrangements, emergency contacts, asbestos information where relevant and the person authorised to re-energise systems.
Explain working hours, noise, dust, hot work, welfare, safeguarding, tenant access, deliveries, lifting, roof access and any rooms or processes that cannot be interrupted. Allow time for communications and staged commissioning.
List required connections between plant, electrical supplies, pumps, controls, BMS, fire alarms, ventilation, drainage and fabric. Confirm who supplies data, containment, builders' work, fire stopping and network access.
Set the required inspection, testing, balancing, pressure or leak checks, functional tests, control sequences, certificates, commissioning sheets, as-fitted information, training, asset labels and outstanding-defect process.
Coordinate tenant comfort, access, HVAC, lighting, controls, landlord plant and out-of-hours work while keeping responsibility boundaries visible.
Learn more about Offices and managed propertyPlan safeguarding, term dates, classroom services, fire and access arrangements, with staged isolations and clear handover information.
Learn more about Schools and educationCoordinate access, infection-control procedures, resilience, hot water, ventilation, plant and records around vulnerable occupants and operational services.

Contact ComGasIt means planning connected systems together, such as heating, pumps, pipework, ventilation, electrical supplies, controls and BMS, rather than leaving interfaces to separate visits. The exact package depends on the building, project boundary and required specialist design or certification.
We can discuss a coordinated package and identify the required mechanical, electrical, controls and specialist inputs. The proposal should state responsibilities, exclusions, competence and certification requirements clearly before work is instructed.
If available, share previous inspection and testing reports, distribution-board schedules, drawings, certificates, isolation arrangements, known defects and any site rules. This helps establish the survey scope and identify whether specialist certification or another inspection route is required.
We can discuss subcontract, specialist or direct-client scopes. Share the programme, drawings, design responsibility matrix, site rules, permits, welfare, information-release dates, testing requirements and principal-contractor arrangements so the scope can be coordinated properly.
Depending on the work, this can include test certificates, commissioning sheets, control settings and sequences, pressure or leak results, asset information, labels, O&M updates, as-fitted drawings, warranties, training and a list of any remaining defects or limitations.
Yes, we can discuss planned preventative maintenance and facilities-management support. The programme should be based on the installed assets, manufacturer instructions, access arrangements, risk profile, service history and the client's reporting and escalation requirements; no fixed response time is implied.
