What Yorkshire homeowners say.
Replaced our 25-year-old boiler in a single day. Tidy, polite, on the dot. Couldn't fault them.
Quoted fixed-price, no surprises. The engineer explained every step. Brilliant from start to finish.
Came out same day when our heating packed in mid-winter. Absolute lifesavers.
Used BASI for years for our annual service. Always punctual, always thorough.
Family-run, Yorkshire through and through. You can tell they actually care.
New Vaillant, 10-year warranty, finance sorted in a phone call. Smoothest install we have had.
Rated 4.8★ from 400+ reviews on Trustpilot and 4.7★ from 200+ on Google. Read more customer reviews from across Yorkshire.
Why it stays consistent
Turned up on time, fixed price, tidy work, a real person.
Read enough reviews and a pattern shows. That is not luck. It is the direct result of using full-time uniformed engineers rather than sub-contractors, quoting a fixed price after a real survey, and answering the phone ourselves. We do not hide the reviews that mention something we got wrong, because that is how we put it right.
See it for yourself
The best test is the work, not the website.
If you are weighing up a new boiler or want to know more about the family behind BASI, the reviews are a fair place to start.
