Where You’ll Work – Woking or Romsey

Woking - You’ll find our Woking site in a modern building on the outskirts of London. Rated excellent for sustainability by BREEAM & Fitwel certified – you’ll feel better for visiting.

Romsey - You’ll find our Romsey site located within beautiful Hampshire countryside, close to the picturesque New Forest District and not far from a superb stretch of the south coast.
