Taxes have nothing to do with the physical location of the company. You go after the owners, and I'm pretty sure you can't open a company in the UK anonymously.

There is an identity and address checks now in the UK.

Even banks are required to validate now, had my bank asking me to validate details even when i have my business for 6 years, same company, same address, and same bank account.
