Turns out this is related to TLS, Companies house have removed support for TLSv1.0, so need to make sure application used 1.1 or 1.2

in my case, adding the following to 'application start' worked (.net framework 4.7.2) (using System.Net;)

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
