A heating system upgrade, not just a new boiler

A heating upgrade with Greentek covers more than swapping the boiler, our Gas Safe engineers also assess radiators, pipework and controls, since an oversized or undersized radiator is one of the most common reasons a room never quite heats up even with a new boiler fitted. We fit Worcester Bosch and Ideal Heating equipment and size the system to the property, not a one-size-fits-all package.

Every installation comes with a written warranty, and because the same team handles insulation work too, we'll flag if a fabric upgrade would let a smaller, cheaper-to-run system do the job just as well.
