Covid 19

Hewitech are following WHO and UK Gov guidelines. Having carried out risk assessments at present we believe we can operate the factory and construction sites within these guidelines with suitable segregation and hygiene regimes.

We will produce at our German factory Ochtrup, and UK factory Cheltenham, and deliver material to sites that remain operational.

 As long as supply routes for transport remain open we will service our customers in key markets, and we are currently aware of capacity within our haulier network.

 We will not jeopardise people’s health, and if advice or our own situations change we will respond accordingly.

 I trust this helps and I will keep you aware of any developments.

Stay safe and well
