Every aspect of boiler servicing, covered

Our Gas Safe and OFTEC-registered engineers deliver the following boiler servicing and maintenance services to homes and businesses across Bristol and the South West.

Domestic Boiler Servicing and Maintenance

Modern households rely on an efficiently-working boiler to keep the home warm and provide occupants with hot water. Regular boiler servicing and maintenance work, whereby a household’s heating system is thoroughly checked, cleaned and tested to ensure all elements are in good working order, is vital in maintaining the health and efficiency of a domestic boiler. Invictus Mechanical’s boiler servicing and boiler maintenance specialists can check your boiler at least once a year to identify signs of a faulty boiler and to keep your family’s boiler working safely and efficiently.

Commercial Boiler Servicing and Maintenance

Boilers that have a 70kW power rating or above are classified as commercial boilers and poorly maintained, inefficient and faulty commercial boilers can be hugely disrupting to businesses. Having a domestic boiler break down is inconvenient and stressful but a commercial boiler breaking down in the middle of a working day could cost you thousands in lost work hours and business, as you’re forced to send staff home until the problem is fixed. To ensure a commercial boiler is kept working at its optimum, it is important to have it regularly serviced and the necessary maintenance work carried out. Invictus Mechanical conduct quality commercial boiler servicing, giving businesses in the South West and further afield peace of mind that all the components of their commercial boiler, including seals, gaskets and heat exchangers, have been checked and are working at their optimal.

Oil Boiler Servicing and Maintenance

All boilers require regular servicing and maintenance if they are to continue working as they should do and avoid becoming faulty or inefficient, and none more so than oil-filled boilers. Invictus Mechanical will take care of your oil boiler servicing and oil boiler maintenance requirements. If your oil boiler does break down, you can trust that one of our engineers will be there as soon as possible to rectify the issue.

 Trustindex verifies that the original source of the review is Google. Excellent service, very thorough and helpful. Identified a problem that was outside the remit of their role but ensured that I had contacted the correct people and requested the appropriate help before they left and was safe. Very worthy of a 5 star rating.
