A practical, evidence-led approach
Building services planned around your premises
Office buildings and mixed-use property portfolios have a broad operational brief: keep people comfortable, protect fabric and services, manage energy, coordinate tenants and complete works without unnecessary disruption. ComGas Services UK Ltd is a Building Services Contractor operating from Farnham since 2019, covering commercial and domestic buildings throughout Surrey and the surrounding southern counties.
We support commercial gas, heating and boilers, plumbing and commercial pipework, mechanical and electrical services, HVAC, air conditioning, BMS, plant rooms, water heaters and maintenance programmes. We can also assist with gas testing, tightness testing, purging and decommissioning, temporary heating, renewables, heat pumps and oil. A portfolio brief should separate planned lifecycle work from reactive defects and make responsibilities, access and tenant communication clear.
Capabilities
Office and property engineering services
Commission a single system survey or coordinate multiple disciplines under one project brief. Service boundaries and landlord, tenant and specialist responsibilities are agreed before work begins.
Commercial plumbing and pipework
Plumbing, water heaters, sanitary services, pipework alterations and leak or failure response, planned around tenant access and isolation requirements.
Learn more about Commercial plumbing and pipeworkMechanical services
Coordinated mechanical works for pumps, ventilation, plant connections and distribution, with clear interfaces to controls, electrical systems and building fabric.

BMS and controls support to improve visibility and operation of connected plant, subject to the existing system, access, design responsibility and client objectives.
Learn more about Building management systemsPPM and maintenance contracts
Planned preventative maintenance and contract options built around agreed assets, frequencies, exclusions, reporting and escalation arrangements rather than an assumed one-size-fits-all schedule.

Operational priorities
What property and office teams need from engineering support
The best scope is not simply a list of trades. It connects asset condition, occupier experience, compliance records, lifecycle decisions and the commercial consequences of taking a system offline.
Occupier comfort and control
Review heating zones, cooling, ventilation, hot water, thermostatic control and complaints history. BMS and controls data can help identify operational issues, but changes should be tested against actual room use and tenant requirements.
Portfolio-wide asset visibility
Create or improve a schedule of boilers, water heaters, pumps, fans, air-conditioning equipment, controls, gas meters and critical electrical interfaces. Consistent asset references make future maintenance and budget planning easier.
Access across multiple tenants
Plan notices, keys, escorts, loading arrangements, landlord approvals, out-of-hours work and isolation windows. A technically simple repair may still require careful coordination in a multi-let property.
Lifecycle and energy decisions
Compare repair, replacement, controls improvement and lower-carbon options in the context of condition, availability, distribution, capital budget and maintainability. Avoid treating a product change as a complete energy strategy.
Evidence for property records
Agree what will be returned after each visit: service sheets, test results, defects, photographs, asset changes, commissioning information and recommendations. Keep records intelligible to both facilities teams and future contractors.
Risk-managed reactive support
Prioritise gas escapes, loss of heating, water leaks, electrical risks and failed plant according to the site’s emergency plan, escalating to emergency support where the situation warrants it and an engineer is available.
Prepare the brief
A better brief for offices and property portfolios
Whether you manage one building or a varied portfolio, the following information helps turn an initial enquiry into a workable scope and comparable proposal.
Property and occupancy profile
State whether the property is single-occupancy, multi-let, mixed-use, vacant or undergoing refurbishment. Include floor areas, critical rooms, tenant contacts and any restrictions on working hours.
Current asset information
Share O&M manuals, asset schedules, service history, defects, warranties, drawings, BMS details, refrigerant information and known statutory inspection records. We can identify missing information during survey.
Access and logistics
Confirm parking, loading bays, permits, roof access, risers, plant-room routes, security, asbestos information and lifting or delivery limitations. These constraints can change method, duration and cost.
Operational priorities
Explain comfort complaints, recurring faults, energy concerns, planned refurbishments, lease events, dilapidations or dates when systems cannot be isolated. Priorities should be ranked, not implied.
Reporting and approval
Name the person who can approve isolation and remedial work, set the required report format and specify how defects are categorised. Agree whether quotations should separate urgent, recommended and lifecycle options.
Handover and future care
Specify asset labels, photographs, test certificates where applicable, controls changes, warranty information and recommended service intervals. Make the record useful to the next person managing the property.
Competence and records
Responsible property engineering
Property owners, employers, landlords, managing agents and occupiers can have different duties depending on the lease, system and work activity. HSE guidance on gas safety, workplace risk, work equipment and asbestos management provides important context; fire, energy and building requirements may also apply. ComGas works to the agreed scope and supplies relevant engineering information, while the client retains responsibility for its own duty-holder arrangements and for confirming which legal requirements apply to the property.
ComGas holds Gas Safe Registration, OFTEC Registration and REFCOM F-Gas Certification, together with 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. These credentials support appropriate tasks; they are not a blanket claim that every system, design or specialist inspection is covered.
For occupied offices, we can help coordinate survey, planned work, isolations, commissioning and handover across landlord or tenant interfaces. For urgent faults, emergency support can be requested, though attendance depends on engineer availability and site access at the time; we do not commit to a specific response time.

Contact ComGasCan ComGas support a portfolio rather than a single office?
We can discuss portfolio work where the locations, systems and reporting requirements can be defined. A useful starting point is a representative survey or asset schedule, followed by agreed priorities and service boundaries.
Do you work for landlords, managing agents and occupiers?
We can scope work for the relevant property stakeholder. The enquiry should identify who controls the system, who can authorise isolation, who receives reports and how tenant access is managed.
Can you combine reactive repairs with planned maintenance?
Yes, the two can be considered together. The proposal should distinguish emergency or remedial attendance from recurring PPM, define exclusions and state how additional defects are reported and approved.
Can you help with a BMS or HVAC review?
We can assess the relevant plant, controls and operating concerns and identify an appropriate scope. Existing system access, manufacturer interfaces, design responsibility and the client’s objectives need to be confirmed.
Can you work around tenants and office hours?
Subject to access and engineer availability, works can be planned around agreed occupancy and shutdown windows. The client or managing agent remains responsible for tenant notices and site permissions.
What records will I receive?
The agreed handover can include service reports, test results where applicable, defect lists, photographs, asset updates, commissioning information and recommendations. The exact record set should be specified at quotation stage.
