Christmas–New Year closure

We will close from Thursday 24 December 2026 and reopen on Monday 4 January 2027.

Samples must be received before Friday 11 December 2026 to allow enough time to complete initial testing and send preliminary results before the closure. Final reports will be sent out when possible.
