Why Choose JJB Heating & Cooling Ltd?

JJB Heating & Cooling is run by Anthony Hunt. Originally from Manchester, Anthony has lived in Dartford for 20 years. He set the business up in 2012 when the firm he worked for was sold. The business traded as JJB Electrical & Heating Services until 2026, when it became JJB Heating & Cooling to focus on new boilers, central heating and air conditioning. Electrical work, including rewires and consumer units, is still part of what we do.

JJB is Gas Safe registered and a Vaillant-approved installer, so we can offer extended Vaillant warranties of up to 10 years on qualifying boilers. All labour carries our own 12-month workmanship guarantee on top.

We are not a call centre. Anthony is your point of contact from quote to handover, and the person you call afterwards. Customers tell us they choose us for reliability, fair pricing and a tidy, careful finish.

Most of our work comes from recommendations and repeat customers, some of whom have used JJB for over a decade. Those long-term relationships are what we care about most.
