A practical, evidence-led approach
Building services planned around your premises
Commercial plumbing is infrastructure, not just a repair at a tap. A leak, failed valve, blocked drain or unreliable hot-water system can affect tenants, staff, customers, production and care. Pipework may also pass through shared risers, ceiling voids, kitchens, plant rooms and occupied areas. ComGas helps facilities managers, landlords, schools, care operators, offices, hospitality businesses and industrial sites investigate the cause, identify the system boundary and plan work that can be tested, maintained and handed back with useful records.
Water quality and safe operation need to be considered alongside the immediate defect. The Water Supply (Water Fittings) Regulations 1999 include requirements for water fittings, drain-down and servicing valves, testing and flushing, hot-water safety and backflow prevention. HSE guidance on Legionnaires' disease places emphasis on managing the risks from water systems. We use those principles to shape surveys and maintenance conversations without suggesting that a contractor visit alone replaces the client's responsible-person arrangements or risk assessment.
Site context
Water systems in Surrey's occupied buildings
Surrey's commercial building stock ranges from older town-centre and converted properties to offices, schools, care buildings, hospitality venues, workshops and larger estates. Existing pipe routes, materials, access panels and isolation points can be difficult to confirm, particularly after several refurbishments. A useful site survey records incoming supply arrangements, storage, boosted systems, hot-water generation, TMVs, outlets, drainage, plant-room access and the areas that cannot be taken out of service.
Surface-water and flooding considerations can affect drainage, plant-room protection and emergency arrangements. Surrey County Council's Local Flood Risk Management Strategy explains the county's approach to surface-water risk and is a useful reference when property teams review drainage routes, low-level plant and external works. The building's own flood assessment and insurer requirements remain controlling.
Access planning should include isolation authority, welfare, deliveries, parking, permits, tenant communications and reinstatement. Surrey County Council provides current roadworks information, which can help a facilities team plan around route or loading constraints. For a multi-occupier building, also identify who can authorise water shutdowns and how affected users will be notified before valves are closed or a riser is opened.
Capabilities
Commercial plumbing and pipework services
We can scope a discrete repair, a planned alteration or a wider water-services package. The starting point is the system function, the risk of interruption and the evidence needed to test and maintain the completed work.
Commercial pipework alterations
New or modified distribution pipework for water, heating and associated building services, subject to survey, materials, supports, access, testing and the required design information.
Learn more about Commercial pipework alterationsHot-water systems
Support for calorifiers, cylinders, unvented or instantaneous water heaters, valves, safety controls and circulation arrangements, with operating and maintenance responsibilities identified.
Learn more about Hot-water systemsPlant-room plumbing
Pipework, pumps, pressurisation, valves, drainage and service clearances in plant rooms, coordinated with heating, gas, electrical and controls interfaces where required.
Learn more about Plant-room plumbingPlanned plumbing maintenance
Planned inspections and maintenance for commercial water systems, defect schedules and follow-up recommendations, aligned with the site's wider PPM and record-keeping arrangements.
Learn more about Planned plumbing maintenanceMechanical services coordination
A joined-up approach where plumbing interfaces with heating, ventilation, pumps, plant rooms or controls and a single site plan is more useful than separate trade visits.

Planning and delivery
Prepare for commercial plumbing or pipework work
The more clearly the water system and operational constraints are described, the easier it is to choose the right survey, parts, isolation plan and test regime.
Map the system and responsibility
Identify the incoming supply, stop taps, tanks, pumps, heaters, outlets, drains and landlord or tenant boundaries. Mark known isolation valves and explain any shared or critical services.
Describe the water demand
Tell us the building use, occupancy, outlet count, peak hot-water periods, kitchen or process demand and any vulnerable users. Note the effect of an interruption on trading, care or production.
Share compliance and risk information
Provide water-system schematics, temperature records, flushing or monitoring logs, Legionella risk-assessment information, previous test results, incident history and details of any water treatment.
Check access and fabric
Identify ceiling voids, risers, concealed pipework, access panels, plant rooms, asbestos information where relevant, floor protection, hot-work controls and routes for removing water or equipment.
Plan isolation and testing
Agree who can isolate, drain and refill the system, how affected occupants will be told, what temporary supply is needed and which pressure, leak, temperature, flushing or disinfection checks will be recorded.
Allow for reinstatement
Confirm requirements for insulation, labelling, fire stopping, access panels, finishes, photographs, updated drawings, operating instructions and any outstanding defects before the work is signed off.
Premises and operations
Plumbing support for Surrey sectors
Schools and education
Plan water shutdowns around pupils, catering, safeguarding, term dates, welfare facilities and the need to return rooms clean and usable.
Learn more about Schools and educationHealthcare and care
Hot-water continuity, temperature control, infection-control procedures, vulnerable occupants and water-risk records should inform the survey and method.
Learn more about Healthcare and careHospitality and commercial kitchens
Kitchen production, sinks, dishwashing, drainage, hot water and backflow protection need coordinated planning around service and cleaning periods.

Shared risers, washrooms, welfare facilities, process services, tenant boundaries and access restrictions can make a small pipework change a wider coordination task.

Contact ComGasCan you work on commercial pipework in occupied premises?
Often, subject to access, isolation, noise, hot-work, hygiene, asbestos and reinstatement controls. The enquiry should identify occupied areas, welfare or production dependencies and the acceptable shutdown window before dates are agreed.
Do the Water Fittings Regulations apply to commercial plumbing?
The Water Supply (Water Fittings) Regulations 1999 contain requirements for water fittings, installation, notification and matters such as backflow prevention, hot-water safety, drain-down and testing. The applicable scope and notification route should be checked for the proposed work with the water supplier or relevant regulator.
Can you help with a Legionella-related plumbing issue?
We can inspect and maintain relevant water-system components and discuss remedial plumbing work. The dutyholder still needs suitable management arrangements, a competent risk assessment and control regime in line with current HSE guidance; a plumbing visit is not a substitute for those responsibilities.
Can you repair a leak without shutting off the whole building?
That depends on the pipework layout, valves, service boundaries and the location of the defect. A survey may identify a local isolation or staged repair; where that is not possible, the work should include communication, temporary arrangements and a controlled drain-down.
What information do you need to quote pipework alterations?
Useful information includes drawings, photographs, pipe sizes and materials if known, the purpose of the alteration, flow or temperature requirements, access, affected users, preferred timing, finishes and any required test or certification records. A site survey may be needed before a firm scope is possible.
Do you provide commercial water-heater support?
Yes, we can discuss servicing, repair, replacement and associated pipework for commercial water heaters. The duty, storage volume, temperature controls, safety valves, circulation, access and continuity requirements should be assessed before work is specified.
