Looking at their own site, it's made in webflow (advertised as "make a website with no code"). It's a GUI, there's no actual web development happening here. Fucking joke that this cost 100k, the business license for webflow is ~£40 a month, though they could have got away with making this site on a basic license.
There's no tech bros in the Tory party really, they clearly don't understand tech at all, it's why we keep getting shafted when they give out all our money and get nothing back.
Ditch your Dyson and get a Henry, support British workers.
