St Joseph’s School in Guildford has used ComGas for years. Julie, the school’s Operations Director, says: “They have completed big projects and undertake regular maintenance for our school. They price fairly, and their work is completed to a very high standard.” From our Farnham base we support Guildford offices, schools, healthcare, retail, leisure and homes with commercial gas, heating and boilers, plumbing, commercial pipework, mechanical, electrical, HVAC, air conditioning, BMS and maintenance services.
Our capability includes gas testing, tightness testing, purging and decommissioning, plant rooms, commercial kitchens, water heaters, temporary heating and renewables as well as domestic heating and plumbing. Gas Safe, OFTEC and REFCOM credentials and relevant commercial, domestic, ACS, WRAS, pipework, catering and testing qualifications support a structured approach. The right next step may be a planned service visit, survey, remedial scope or maintenance review rather than an assumed response.
Guildford’s urban mix means a boiler replacement, catering-gas alteration or HVAC survey can involve occupied spaces, shared access, landlord approvals and isolation planning. Where the job forms part of a larger regeneration or refurbishment project, identify interfaces with the main contractor, design team and utilities early.
Select the service that matches the building requirement; related disciplines can be considered together where the scope warrants it.

Learn more about ComGas Heating CareGuildford sites benefit from an enquiry that covers both the technical requirement and movement around the building:
Town-centre, riverside, station-side, residential and business-park sites can have different loading, parking, security and pedestrian constraints.
Tell us about trading, teaching, clinical, care, events or customer-facing hours so isolation and noisy works can be assessed.
Provide principal-contractor details, programme information, permits, drawings and utility interfaces where the work sits inside a refurbishment or regeneration project.
For catering premises, share appliance schedules, extraction information, gas pressures, planned shutdown windows and any commissioning or testing records.
If the brief includes heat pumps, controls, electrification or efficiency, provide heat-demand, emitter, electrical and BMS information where available.
