TPI Flue Gas Analysers: Free First-Year Calibration | Test4Less
Free first-year calibration on any TPI flue gas analyser
Buy a new TPI flue gas analyser from us by 31 December 2026, and TPI will service, calibrate and certify it free when it’s due. Worth £95 – £110.
What you get
A full service inspection
TPI’s own technicians go over your analyser to their standard service procedure. You get it back in good working order for another year of boiler work. If they find a problem, they tell you and give you a price before touching it.
Calibration
TPI checks your analyser’s readings and adjusts it so they’re accurate again. Those are the CO, CO2 and O2 numbers on every service sheet and gas safety record you sign, so they need to be right.
A calibration certificate
This is your proof the analyser was calibrated. Keep it in the van or on your phone, ready for a landlord, a main contractor or a Gas Safe Inspector who asks to see it.
How to claim
- Buy it by 31 December. Any new TPI flue gas analyser bought from Test4Less between 1 October and 31 December 2026 counts.
- Register it with TPI by 31 January. You'll need the serial number and your Test4Less invoice.
- Book your service when it's due. Book it through TPI any time in the 14 months after you buy. TPI won't book it for you, so put a reminder in your diary now.
Note: Miss the 31 January deadline at the offer’s gone. TPI won’t make exceptions, so register as soon as your analyser turns up.
