Can somebody recommend me a Service Address company?

[VectraMan]

My home office is my registered address and my trading address.

The trading address is where my VAT letters (now emails) are sent to. All perfectly legal.

Yep. My (rented) home is used for everything company related. I've never heard anything that said differently, and it's none of my landlord's business as far as I'm concerned.

The registered office is only for a couple of official letters a year (like the annual return and accounts reminder). Paying extra for a registered office service is dumb.
