Ascent Commercial Gas Engineers Ltd provide commercial plumbing, heating and mechanical maintenance services throughout Lancashire.
Our focus is on commercial premises and plant rather than domestic plumbing. We support businesses with repairs, maintenance and replacement of suitable components associated with heating, hot-water and commercial water systems.
This makes Ascent particularly useful for sites where the fault crosses between the gas appliance and the wider mechanical system. Instead of simply attending to the boiler, we can investigate suitable associated pumps, valves, pressurisation equipment and system components.
Our services include:
• Commercial Plumbing Repairs
• Plant Room Plumbing & Mechanical Work
• Heating System Repairs
• Hot Water System Repairs
• Pump Replacement & Maintenance
• Pressurisation Unit Replacement
• Expansion Vessel Replacement
• Commercial Valves & Controls
• TMV Servicing & Replacement
• Hot & Cold Water Fault Finding
• Pipework Repairs & Alterations
• Leak Investigation & Repairs
• System Filling & Recommissioning
• Planned Preventative Maintenance
• Commercial Plumbing Remedial Works
Commercial plant rooms can contain far more than boilers.
Pumps, pressurisation units, expansion vessels, valves, heating pipework and hot-water equipment all contribute to the operation of the wider system.
Ascent provide commercial plant room plumbing and mechanical services throughout Lancashire, helping businesses maintain and repair suitable associated equipment alongside their commercial heating plant.
Where a heating or hot-water problem isn't caused directly by the gas appliance, we can investigate the wider system and identify suitable remedial work.
Problems within the wider heating system can sometimes appear to be boiler faults.
Poor circulation, pressure problems, failed pumps, defective valves or other system issues can prevent commercial heating from operating correctly even when the boiler itself is functional.
Our engineers can investigate suitable commercial heating systems and undertake appropriate repairs involving components such as:
Pumps • Valves • Pressurisation Units • Expansion Vessels • Heating Pipework • Associated Controls
This complements our commercial boiler servicing and repair capabilities and allows us to investigate more of the complete heating system.
Circulation pumps are an important part of many commercial heating and hot-water systems.
A failed or poorly performing pump can contribute to:
Poor circulation • Reduced heating performance • Hot-water problems • System faults • Loss of heating to parts of the building
Ascent can investigate suitable pump faults and replace appropriate commercial heating and hot-water circulation pumps where required.
Commercial sealed heating systems frequently use pressurisation equipment to maintain the required system pressure.
Faults with a pressurisation unit can result in pressure problems and disruption to the operation of the heating system.
Ascent provide pressurisation unit fault finding and replacement throughout Lancashire as part of our wider commercial plant room services.
Where a new unit is installed, the system can be appropriately refilled and recommissioned as required.
Expansion vessels play an important role in sealed heating and hot-water systems.
Problems with vessel charge, diaphragm condition or sizing can contribute to pressure fluctuations and other system issues.
Our engineers can assess suitable commercial expansion vessels and undertake appropriate maintenance or replacement where required.
Commercial heating and hot-water systems can contain numerous valves controlling flow, isolation and operation across the installation.
Ascent can undertake suitable repairs and replacement of commercial valves and associated plant room components.
This may include work required as part of a wider boiler repair, heating-system fault, planned maintenance visit or plant-room remedial programme.
Thermostatic mixing valves are widely used within care homes, healthcare environments, hotels and other commercial premises to control water temperature at outlets.
Ascent provide suitable TMV inspection, servicing, fault finding and replacement throughout Lancashire.
Where a TMV isn't maintaining the required outlet temperature or has another operational problem, we can investigate the valve and advise on appropriate remedial work.
TMV work can also be coordinated with wider commercial hot and cold water maintenance.
Problems within commercial hot and cold water systems can sometimes require investigation beyond an individual tap or outlet.
Examples can include:
Temperature problems • Poor flow • Failed valves • Circulation issues • TMV faults • Localised pipework problems • Hot-water system faults
Our commercial plumbing service allows us to investigate suitable faults and determine the appropriate repair or further action.
Care homes can contain extensive heating, hot-water and plumbing systems requiring regular maintenance.
Ascent support care facilities throughout Lancashire with suitable:
Plant Room Maintenance • Heating System Repairs • Hot Water Systems • Pumps • Pressurisation Units • Expansion Vessels • TMVs • Commercial Plumbing Remedials
Because we also provide commercial gas engineering, boiler servicing, water-heater maintenance and gas safety services, more of the site's mechanical requirements can be coordinated through one contractor.
Hotels and hospitality premises rely heavily on dependable heating and hot-water systems.
Our commercial plumbing and mechanical services can support suitable:
Heating Systems • Hot Water Systems • Plant Rooms • Pumps • Valves • TMVs • Pipework Repairs
Where premises also contain commercial boilers, gas-fired water heaters or catering equipment, our wider commercial gas capabilities provide additional support.
We provide commercial plumbing and mechanical support for:
🏥 Care Homes & Residential Facilities
🏨 Hotels & Hospitality
🏭 Factories & Manufacturing Facilities
🏫 Schools & Education
🏢 Offices & Managed Commercial Properties
📦 Warehouses & Commercial Units
🍽️ Restaurants & Commercial Kitchens
🔧 Workshops & Engineering Premises
We work directly with businesses as well as facilities managers, property managers and maintenance providers.
Commercial plumbing and mechanical equipment can be incorporated into wider planned preventative maintenance arrangements.
Depending on the premises and equipment, this can include suitable checks and maintenance involving heating systems, pumps, pressurisation equipment, expansion vessels, TMVs and associated plant.
This can be coordinated alongside commercial gas appliance servicing to make ongoing plant-room maintenance easier to manage.
One of the main advantages of using Ascent is our ability to support more than the individual boiler or gas appliance.
Our wider services include:
Commercial Boiler Servicing & Repairs • Commercial Heating • Commercial Water Heaters • Commercial Gas Safety Certification • Commercial Kitchens • Gas Tightness Testing & Purging
For facilities managers and businesses responsible for larger premises, this can reduce the need to arrange separate contractors for every fault affecting the plant room.
