Certificate for Every Pump
Every pump we calibrate is tested against a calibrated measure and issued with a certificate showing the as-found and as-left readings — a record that stands up to an audit.
Fuel Pump and Dispenser Calibration
Every litre should be accounted for. BMS provides on-site fuel pump and dispenser calibration for commercial sites across the UK, testing each pump against a calibrated measure and issuing a certificate you can put in front of an auditor. A pump that over-dispenses by just one per cent can give away thousands of litres a year at a busy depot without anyone noticing; one that under-dispenses on a pump used for trade is a Weights and Measures problem. We calibrate for fleet operators, emergency services, airfields, defence sites and fuel retailers, recording exactly what we found and what we adjusted on every visit.

Resale & Own-Use, Explained
Selling fuel and fuelling your own fleet sit under different rules. We explain which apply to your pump and calibrate accordingly, whether it's a legal requirement or a stock-accuracy check.
All Fuels, Pumps & Major Makes
Diesel, petrol, AdBlue, gas oil, HVO and aviation dispensers, across all major pump makes — one specialist for every fuel and every pump on site.
One Visit, Figures That Reconcile
Book pump, tank gauge and fuel management system calibration together on a single visit, so the figures across all three agree with each other.
Why Fuel Pump Calibration Matters
Meters drift as they wear, and a small drift adds up. For a resale pump, accuracy is a legal requirement; for an own-use fleet pump, it keeps stock figures, fuel management reports and unexplained losses from drifting apart.
What a BMS Calibration Visit Includes
Our engineer pre-checks the pump, tests it against a calibrated measure, records the as-found reading, adjusts if needed, records the as-left reading, reseals the pump and issues your certificate — with every reading logged against the pump’s serial number.
Calibration After a Repair or Meter Change
Any work that could affect accuracy, a meter change, or a repair to the metering element means the pump may need to stay out of use for trade until it’s re-verified.
Fuels, Pumps and Makes We Calibrate
We calibrate dispensers for diesel, petrol, AdBlue, gas oil, HVO and more.
Standards and Regulations
Our calibration work is carried out with reference to the Weights and Measures Act 1985, the Measuring Instruments Regulations (MID, MI-005), OPSS guidance, and JIG/EI standards for aviation or JSP 375 for MOD sites where relevant.

What Our Clients Say About Us
Fuel Pump Calibration FAQs
Is fuel pump calibration a legal requirement?
Yes, if the pump is used to sell fuel. Weights and Measures legislation requires pumps used for trade to be of an approved pattern, sealed and accurate within the legal limits, verified by an approved person. If the pump only fuels your own vehicles, calibration isn’t usually a legal requirement, but it’s the only way to trust your fuel records.
Do I need calibration if we only fuel our own vehicles?
It’s not usually a legal requirement for an own-use fleet pump, but an uncalibrated meter can drift enough to make your stock records, fuel management reports and cost allocation unreliable, which often looks like fuel loss or theft when it isn’t.
Will I get a calibration certificate, and is it traceable?
Yes. Every pump we calibrate gets a certificate showing the as-found and as-left readings, recorded against the pump’s serial number.
Does my pump need re-calibrating after a repair?
Yes. Any repair or replacement that could affect the metering element means the pump should be rechecked before you rely on the reading, and a resale pump must not be used for trade again until it’s re-verified.
