There are three types of company you can form on our website. 1) Company limited by shares. These can be formed by one person who can be the only shareholder and director. Or by many shareholders with many directors. They are the most popular company trading structure in the UK. 2) Companies Limited by Guarantee. This type of company structure is normally used for non-profit organisations such as clubs, associations, charities and social enterprises. Instead of shareholders, they have guarantors who guarantee a minimal amount, usually £1. A company limited by guarantee can be formed with 1 person being the only guarantor and director. 3) Limited Liability Partnerships. This type of company structure is commonly used by professional organisations such as accountants, engineers and solicitors. The LLP structure allows flexible profit-sharing arrangements amongst the partners. LLPs require at least two persons as partners.
