COVID-19 restrictions to remain in place at The Walton Centre

Restrictions remain in place across the NHS in relation to the COVID-19 pandemic. The safety measures in place over the 18 months therefore remain in place at The Walton Centre - and in our other clinic settings within the community – until further notice.

Due to the increased transmission risk posed by the Omicron variant, visiting has been suspended within The Walton Centre except for exceptional circumstances.
