Servicing & Maintenance

Throughout Wales and the West of England. We are qualified to work on all commercial boiler makes & models.




We understand the importance of an efficient boiler system to your business.

At Total Boiler Services, we make sure our client’s boilers are serviced on a regular basis to ensure they run to their optimum level, keeping your fuel costs low and your heating and hot water regulated.

Any boiler unit that has a 70kW power rating and above is defined as a commercial boiler. You should always use a commercial boiler specialist like Total Boiler Services as we have the qualifications and experience of servicing, repairing and installing all types and sizes of commercial boilers. 

If you are a landlord then you have a legal requirement to have any gas appliances gas safety checked every 12 months, and this can be done at the same time as your boiler service. Total Boiler Services engineers are all Gas Safe Registered and are qualified to carry out the required inspections, providing you with a Landlord Gas Safe Certificate when completed. 

Although highly effective, modern boilers are complex pieces of equipment and there are times when their components can fail. A commercial boiler service checks that your boiler is compliant with current boiler regulations (which are consistently being updated) and that it is functioning safely and efficiently, minimising the likelihood of it breaking down.

A regular boiler service ensures your commercial property and business have continuous and regulated heating, and hot water, minimising the risk of it breaking down during operating hours. Being without heat and or hot water can really disrupt your business and a regular service by Total Boiler Services will ensure it is running safely and efficiently.
