New company formation - registered address

[theplayingmantis]

We are setting up a holiday let and forming a company to do so. 0 experience of this, but we do not want to use home address as registered or directors address on Companies House.

we being quoted 300quid a year to set a po box by our tax advisor, which rudimentary googling suggests is excessive - there are a number of websites that come up offering registered address services for under 50 quid a year, are they legit?

eg registeredaddress.co.uk or yourcompanyformations.co.uk

any advise gladly received
