GET IN TOUCHKeston Boiler Servicing
Keston highly recommends that you carry out an annual boiler service. Why is this so important? Well, not only does it mean that it will run more efficiently and effectively, but most importantly it will mitigate any potentially hazardous situations that an unmaintained boiler may bring. As with all boilers, your Keston boiler will produce harmful by-products such as carbon monoxide if it doesn’t burn properly. With this in mind, we will carry out a full service and make sure that it meets all current regulations which will give you peace of mind that all is safe within your home.
