This setup was not initially approved, see 1.7 in the document:
> 1.7 Unlike all other IT systems and services, the OBR’s website is locally managed and outside the gov.uk network. This is the result of an exemption granted by the Cabinet Office in 2013. After initially rejecting an exemption request, the Cabinet Office judged that the OBR should be granted an exemption from gov.uk in order to meet the requirements of the Budget Responsibility and National Audit Act. The case for exemption that the OBR made at the time centred on the need for both real and perceived independence from the Treasury in the production and delivery of forecasts and other analysis, in particular in relation to the need to publish information at the right time.
Gov.uk does not use some random wordpress plugin to protect information of national significance, doco at https://docs.publishing.service.gov.uk/repos/whitehall/asset...
