When a commercial boiler fails, the priority is identifying the cause of the problem and restoring heating or hot water as quickly and safely as possible.
Ascent Commercial Gas Engineers Ltd provide commercial boiler fault finding and repairs throughout Preston, supporting businesses with both routine repairs and urgent breakdowns.
Based locally in Preston, our engineers work on individual commercial boilers as well as multi-boiler systems and larger commercial plant rooms.
Our commercial boiler services in Preston include:
Commercial heating failures don't always happen during normal working hours.
A boiler breakdown can leave care homes without adequate heating or hot water, disrupt hotels and hospitality businesses, affect schools and workplaces or cause problems within industrial and commercial premises.
Ascent provide 24/7 emergency commercial boiler call-outs throughout Preston.
If you've completely lost heating or hot water, multiple boilers have failed or an essential commercial boiler has developed an urgent fault, contact us on:

A boiler that repeatedly locks out or requires constant resetting usually needs the underlying problem investigated.
Commercial boiler faults can involve ignition systems, flame proving, burners, controls, sensors, safety devices, combustion, gas supply or components elsewhere within the heating system.
Our engineers take a systematic approach to fault finding rather than simply repeatedly resetting the appliance or replacing components without establishing the cause.
Where possible, we'll identify the fault and carry out the appropriate repair during the initial visit.
If manufacturer-specific parts are required, we'll explain what's needed and arrange the necessary follow-up work.
We provide servicing, fault finding and repairs for commercial boiler equipment from leading manufacturers including:
Commercial boiler fault finding, servicing and repairs for suitable Ideal commercial heating equipment.
Diagnostics and repairs for Hamworthy commercial boilers and multi-boiler installations commonly found within larger commercial plant rooms.
Commercial boiler servicing and fault finding for Remeha heating equipment installed within commercial premises.
Fault finding, servicing and repairs for suitable Vaillant commercial heating installations.
Commercial boiler diagnostics, servicing and repairs for suitable Bosch commercial heating equipment.
If your boiler manufacturer isn't listed, send us the make, model and fault information and we'll confirm whether we can assist.
We provide commercial boiler breakdown support across a wide range of premises throughout Preston.
These include:
Care Homes • Schools • Nurseries • Hotels • Pubs • Restaurants • Factories • Warehouses • Offices • Workshops • Commercial Properties • Industrial Sites
We also work with facilities managers, property managers and maintenance companies responsible for commercial heating equipment across single or multiple premises.
A breakdown can sometimes highlight wider maintenance requirements within a commercial heating system.
Alongside reactive repairs, Ascent provide commercial boiler servicing, planned preventative maintenance and ongoing service contracts.
Regular servicing gives engineers an opportunity to assess equipment condition, identify developing problems and address maintenance requirements before they contribute to future breakdowns.
For businesses with multiple boilers or commercial heating appliances, we can discuss a planned maintenance programme covering the equipment across your premises.
Ascent Commercial Gas Engineers Ltd are based in Bamber Bridge.
Being locally based means we're well positioned to provide planned and reactive commercial boiler support to businesses throughout Preston and the surrounding area.
Alongside commercial boiler repairs, our engineers provide commercial boiler servicing, gas safety certification, industrial heating maintenance, commercial catering gas services and specialist commercial gas engineering.

If your commercial boiler isn't firing, repeatedly locks out, has lost heating or hot water, or has developed another fault, contact Ascent Commercial Gas Engineers Ltd.
When reporting a breakdown, it can help to provide the boiler manufacturer, model, displayed fault code and photographs of the appliance/data plate where available.
This can help us understand the equipment and fault before attendance.
