Any electricians out there, who know about PRI tes

[slice2020]

I live in a new build and run a small beauty business from home. I live in Scotland and now all these new regulations have came in and they say I need a PRI and PACT test. I don't mind the PACT tests but tests are really taking the biscuits as i have been quoted £400 and it is a brand new house. Is it at all justified in a new property?
