What is a partnership? 

There are two main types of partnerships:

Limited Partnership (LP) consists of two or more partners, who can be individuals or corporate entities (such as another company or LLP). The partners can be located in any country around the world, but the partnership must have a principal place of business in the UK. This is similar to a UK company having a registered office.

In a Limited Partnership, there are 2 types of partners, and they have different roles and responsibilities. Each LP must have at least one General Partner AND one Limited Partner.

Limited Liability Partnerships (LLPs) – allow for a partnership structure where each partner's liabilities are limited to the amount they put into the business. Having business partners means spreading the risk, leveraging individual skills and expertise, and establishing a division of labour. In an LLP, each partner is not responsible or liable for another partner's misconduct or negligence.

You can register as a partnership online on the gov.uk website.
