## Summary

The Met Office bought a one-off indoor solar calibration unit, model SRC02, from Hukseflux Thermal Sensors B.V. The equipment is for the Met Office QA Laboratory and supports calibration of pyranometers used across the Met Office’s operational observation networks. This is a specialist laboratory instrument purchase within laboratory, optical and precision equipment, rather than a general solar installation or routine calibration service. Delivery is in the United Kingdom. The requirement is focused on supplying the unit needed for instrument calibration; the stated purpose is to help maintain calibration of pyranometers across operational observing networks.

The procurement is complete and the contract is active. The Met Office used a direct award below the applicable threshold, without competition. Hukseflux Thermal Sensors B.V. was selected as supplier. The contract was signed on 14 August 2026 and runs from 15 August 2026 to 31 January 2027. Its value is £38,442.95 excluding VAT (£46,131.54 including VAT). The purchase was treated as one lot and the stated evaluation basis is the direct award route; no separate competitive scoring or award criteria are recorded. This is a single equipment purchase, rather than a framework or multi-supplier arrangement.

For suppliers looking to serve this buyer’s future requirements, the relevant capability is supplying specialist solar measurement and calibration equipment suitable for laboratory quality assurance and use with operational weather-observation networks. A credible competitor would need to demonstrate that its instrument can support pyranometer calibration and meet the Met Office’s technical and operational needs, alongside the capacity to deliver a complete, specialist unit. The selected supplier is an established thermal-sensor manufacturer, indicating that a supplier with relevant instrumentation expertise and a dependable product offering is well placed for this narrowly defined requirement. This purchase provides evidence of demand for an indoor solar calibration unit, rather than a wider package of solar-energy equipment or calibration services.
