When your heating system serves a commercial building, factory, school, hotel or other large facility, downtime is not an option. AGW Group Ltd’s commercial boiler repairs and commercial boiler maintenance services deliver the reliability, safety and performance your business demands. Whether you’re dealing with a breakdown or seeking a proactive maintenance plan, we specialise in keeping commercial heating systems in optimal condition.
Regular commercial heating maintenance is the first line of defence against expensive failures. Our commercial boiler servicing includes detailed inspections, cleaning, testing, and reporting—ensuring safety, regulatory compliance, and energy efficiency. A well-maintained boiler system runs more reliably, lasts longer, minimises unplanned outages, and helps reduce energy bills.
Regular commercial boiler maintenance, whether it be Gas, Oil, Solid-fuel, LPG, Multi-fuel or even environmental favourites such as Biomass and Air Source Heat Pumps, is an essential task that ideally should be carried out yearly but more frequently if you have an older system.
Our Commercial Boiler Maintenance Contracts for businesses in Andover and across Hampshire, can help identify any potential faults before they occur and ensure worn parts are replaced and repairs are carried out. We have a team of highly experienced, Gas Safe registered engineers who carry out all annual servicing, gas safety checks and repair and maintenance works to the highest standards.
Should a fault occur, our skilled engineers are ready to respond rapidly.
Our commercial boiler maintenance contracts include us carrying out the following:
Regular maintenance of any boiler system helps prolong the life of the boiler, maintains efficiency, saves money and gives you peace of mind.
We work on all major boiler brands, multi-boiler installations, plant rooms, and complex systems. In an emergency our aim is to restore service fast and efficiently to minimise disruption to your operations. That’s why we’re the first choice for commercial boiler servicing in Hampshire.
Rather than one-off visits, many clients benefit from a Planned Preventative Maintenance (PPM) contract. These ongoing contracts might include:
Quarterly, biannual or annual inspections
Flue and combustion analysis
Cleaning of burners, heat exchangers, filters
Inhibitor dosing, water quality checks
Control system calibration
Safety & compliance checks, reports, certification
Priority response for breakdowns and preferential rates
We customise each PPM contract to suit your building size, system complexity, budget, and risk profile.
To ensure you meet with housing regulations and provide your tenants with an efficient and safe heating system, we provide a contract based service that takes the worry away from you.
Current legislation states all gas appliances should be inspected annually by a Gas Safe registered engineer. We plan regular inspection visits to your properties in line with the required inspection schedule and provide copies of Gas Safety Records (CP12 Certificates) to you so you can provide a copy to your tenants.
This helps to ensure your properties boilers are maintained and working efficiently at all times and your tenants have piece of mind that their heating and hot water system are being maintained safely and legally. Should any repairs or replacements be needed we’ll report back to you with the necessary information and remedial action taken.
In a worse case scenario our team of heating specialists can supply and install a new boiler for your property.
If your boiler has stopped working or doing something it shouldn’t be, give us a call and we’ll take a look and feedback to you what’s needed to get things back up and running as soon as possible.
We also provide service contracts, specifically designed to help you reduce your operating costs, extend the life of your boiler and heating system and ensure safe, legal operation.
Our Commercial Boiler breakdown services include emergency call-outs, repairs, and preventative maintenance to restore heating and hot water, as well as ongoing service contracts to prevent future problems.
