From emergency repairs to annual servicing and new installations, we are OFTEC specialists who understand oil fired systems inside and out. Professional service, expert knowledge, reliable results.
OFTEC recommends a service at least once a year. A yearly service by an OFTEC certified engineer keeps your boiler running safely, is often a condition of the manufacturer's guarantee, and catches small faults before they turn into breakdowns. Our engineers work across Watford, Hertfordshire and surrounding areas, subject to availability. Here's why homeowners choose our service:
