Compared with most other countries, it is very cheap to set up a company in England and Wales, Scotland or Northern Ireland. The statutory registration fee charged by Companies House in each of the jurisdictions (the government agency that registers companies) is £40 if the application is made by sending papers to Companies House and £13 if the company is registered electronically. There will also be the costs of preparing the company's articles of association, providing statutory registers, etc.
The quickest and most effective way to have a company registered is to use the on-line registration service provided by Incorporation Services Limited, part of the Company Law Solutions group of companies. We provide a standard service at £145 and a basic service at £61, in both cases including the registration fee and VAT.
