About Gaswise
Your local Marchwood heating engineer
Gas Safe registered, Glow-worm approved and Marchwood-based — heating you can rely on.
Who we are
A one-man band, done properly
Gaswise Heating Engineers is run by Chris Wiseman, a Gas Safe registered heating engineer based on Kestrel Close in Marchwood. From boiler changes and annual services to breakdowns, powerflushing and landlord safety certificates, Chris looks after gas and heating for homes across Marchwood, Totton and the Waterside.
As a Glow-worm approved installer, Chris can fit and register manufacturer-backed boilers with the extended guarantees that come with them. Because it’s just Chris on the job, you get one experienced pair of hands from the first phone call to the final test — no call centres, no surprises, and work left clean and tidy.
