Structured building-services support for public estates, where accountability, procurement, public access and long-term value shape every project.
Public-sector estates span offices, schools, civic buildings, libraries, community facilities, depots, leisure premises, housing-related buildings and other public-facing sites. Engineering work must respect budgets, procurement routes, safeguarding, public access, carbon objectives and the need to retain a clear audit trail. ComGas Services UK Ltd is a Building Services Contractor founded in 2019 and based in Farnham, working on commercial and domestic buildings across Surrey and the surrounding southern counties.
Our capability includes commercial gas, heating and boilers, plumbing and pipework, mechanical and electrical services, HVAC, air conditioning, BMS, plant rooms, water heaters, temporary heating, renewables, heat pumps and oil. We also support gas testing, tightness testing, purging, decommissioning and commercial catering gas. We can work within an agreed procurement and contract structure.
We can support a defined project, a survey-led programme or agreed planned maintenance. Procurement route, specifications, approvals and client standards should be confirmed at enquiry stage.
Gas, commercial boiler and heating support for civic, education, community, office, depot and other public buildings, with testing and documentation requirements defined in the scope.

Learn more about Testing, purging and decommissioningA public-sector brief needs to demonstrate more than technical intent. It should connect the building outcome to procurement, governance, users, records, lifecycle value and the client’s own policies.
Define outputs, assumptions, exclusions, options and handover requirements so proposals can be compared fairly. Separate urgent safety work from discretionary improvements and longer-term capital options.
Plan work around visitors, staff, pupils, residents, service users, events and accessibility. Segregate work areas, control tools and materials, maintain routes and coordinate communication with the responsible site team.
Identify buildings or rooms where loss of heat or hot water affects vulnerable users, operations or statutory services. Consider plant condition, redundancy, temporary measures and realistic approval routes without promising uninterrupted service.
Assess controls, heat loss, plant condition, heat pumps, renewable options and fuel choices against building fabric, distribution, electrical capacity, maintenance and whole-life cost. A technology label alone is not a complete decarbonisation plan.
Maintain clear tender, survey, testing, commissioning, defect, approval and handover records. Asset references and consistent reporting support future procurement, compliance reviews, budgets and public accountability.
Confirm vetting, escort, induction, school or care-site rules, data or security restrictions, permits, asbestos information and who can authorise isolation. Contractor arrangements must align with the client’s policies.
The clearer the procurement, technical and operational context, the easier it is to submit a proportionate and auditable proposal.
List the sites, building uses, users, opening periods, asset types, critical spaces, access controls and any safeguarding or public-interface requirements. Identify whether the work is reactive, planned or capital.
State the required output, specification, contract form, framework or tender route where applicable, approval thresholds, pricing format, insurance requirements and any client templates. Do not assume a route that has not been confirmed.
Share surveys, drawings, asset schedules, O&M manuals, service history, energy data, BMS information, warranties, gas records and asbestos information. Flag gaps so survey allowances are realistic.
Identify term-time or event constraints, public opening, restricted hours, shutdown windows, decant plans, temporary heating needs, traffic management and milestone approvals. Separate target dates from guaranteed dates.
Name the contract manager, authorised representatives and stakeholders. Define progress reports, variation control, defects, testing, commissioning, handover, training and records required for audit.
Set out energy, carbon, refrigerant, heat-pump, renewable, fabric and maintenance objectives. A practical assessment should address electrical capacity, distribution, controls, space, funding and whole-life implications.
Public bodies and local authorities must apply their own procurement, governance, health-and-safety, safeguarding, accessibility, environmental and estates policies. GOV.UK procurement guidance and HSE guidance provide general context, while education, healthcare, housing, leisure and civic settings may carry additional requirements. ComGas can provide agreed engineering services and supporting records; the contracting authority remains responsible for its procurement decisions, duty-holder arrangements and confirmation of applicable standards.
ComGas is Gas Safe Registered, OFTEC Registered and REFCOM F-Gas Certified, with further 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 in place. These credentials should be matched to the works package and do not by themselves confirm appointment to a framework, approval by a public body or competence for every specialist system.
We can help plan surveys, shutdowns, testing, commissioning, records and close-out within the agreed contract. Emergency support can be requested.

Contact ComGasWe can review an enquiry and respond through the procurement route and requirements identified by the contracting authority. A page description does not constitute framework membership, public endorsement or an offer to bypass procurement.
Subject to the client’s access, safeguarding, permit and risk arrangements, work can be planned around occupancy and agreed shutdown windows.
Renewables and heat-pump options can be assessed as part of a wider building-services brief. Feasibility depends on fabric, heat demand, electrical capacity, distribution, controls, space, permissions, maintenance and budget.
We can discuss surveys, scopes and technical information within an agreed commission. The client should confirm who owns design, specification, procurement, evaluation and statutory approvals before work begins.
The contract or work order should define approval, quotation, reporting and close-out. We can record defects and recommendations clearly, but additional work is not assumed to be authorised without the client’s approval.
Yes. Call 01252 214120 and we will confirm when an engineer can attend. If you smell gas or suspect a leak, call the National Gas Emergency Service on 0800 111 999 first.
