Oil Boilers & 
Oil Tanks

Using trusted manufacturers and quality parts we strive to ensure that you are fitted with current market leaders in oil boilers. Choosing a quality system will ensure that you get maximum efficiency over the lifetime of the system.

Oil tanks frequently fail in Shetland's harsh and unforgiving climate, we ensure that these meet safety standards and advise accordingly on whether these need replacing. Oil spills pose a significant environmental hazard - not to mention the expense of a clean-up operation.
