About 10 miles from our Farnham base.
Alton is a market town in East Hampshire with an established centre, residential areas, schools, community uses and employment premises. ComGas supports commercial and domestic properties with gas, heating and boilers, plumbing and pipework, mechanical and electrical services, HVAC, BMS, water heaters and planned maintenance.
A useful brief should identify the age and condition of the system, occupancy, access, isolation points, flues, controls and the records needed at handover. We can help with a service, repair, replacement, plant-room project, gas test or energy-improvement discussion. Emergency Response can be requested.
ComGas can support Alton clients with a defined repair, a heritage-aware survey, an installation or a wider maintenance discussion, matched to the building and its constraints.

View projectAlton projects should connect technical decisions with the property and its local setting. Consider:
Establish whether the address has conservation, listed-building, landlord or other restrictions affecting flues, plant, penetrations or external units.
Plan timed unloading, pedestrian protection and routes through the building for boilers, cylinders, pumps and plant-room components.
Define occupancy, hot-water demand, storage, temperatures, controls and peak-use requirements before selecting equipment.
Where relevant, compare controls, heat-pump or renewable options with fabric, electrical capacity, emitter, noise, planning and maintenance constraints.
Agree certificates, commissioning information, asset schedules, defects and user guidance before the work is closed.
The Alton building types below show why access, risk controls, continuity and record requirements must be established for the actual premises.
