What our customers say
Every review below was left on our Google Business Profile by a customer we have actually worked for. Nothing here is written by us.
A family-run gas and heating firm, not a national call centre
Instantheat LTD has been fitting boilers, heating systems and bathrooms across Greater Manchester since 2006. We work from two bases — Whitefield in the north and Romiley in the south east — which between them put an engineer within a short drive of most of the region. When you call, you speak to the people who will actually turn up and do the work.
Every gas job we carry out is done and certified by a Gas Safe registered engineer under registration 201600, which you can check yourself on the Gas Safe Register. That matters more than it sounds: gas work carried out by anyone unregistered is illegal, invalidates your home insurance, and is genuinely dangerous. It is worth asking any trade you contact for their number, not just us.
We quote fixed and upfront after seeing the job, not over the phone off a photo. If something turns out to be more involved than it first looked, we tell you before we start rather than after. That approach is why most of our work still comes from people we have worked for before, or from someone they have passed our number on to.
Comprehensive plumbing & heating services
Boiler replacements
Combi, system and back-boiler conversions, with the old unit removed, the new one commissioned and combustion tested, and Building Control notified.
Heating installations
Full system design and fitting — pipework, radiators, controls and zoning, balanced properly so every room actually reaches temperature.
Bathroom renovations
End-to-end refurbishment, from re-routing waste and supply pipework through to fitting and sealing the finished suite.
Underfloor heating
Manifolds, zoned pipe loops and commissioning, with every loop pressure tested before the floor goes down over it.
General plumbing
Leaks, pipework, taps, toilets and appliance fitting — the small jobs that stop being small if they are left.
