The Enterprise Investment Scheme (EIS) plays an important role in the UK's investment landscape, helping early-stage businesses attract funding while offering tax incentives to eligible investors. As a result, a wide range of firms now provide EIS-related services, from tax and compliance advice to investment structuring and fundraising support.
The UK market includes specialist tax advisers, accountancy firms, investment managers and corporate finance consultancies, each bringing a different perspective to the EIS process. Some focus on helping investors understand the available reliefs, while others work closely with growing businesses seeking to raise capital or navigate HMRC requirements.
This guide highlights a selection of firms offering EIS services in the UK. Rather than ranking providers, it provides practical context on the types of services available, the organisations these firms typically support, and the areas in which they have developed expertise. Whether you're an investor exploring tax-efficient opportunities or a business considering EIS as part of a funding strategy, understanding the different approaches can help you identify the support that's most relevant to your circumstances.

Some firms focus on helping startups prepare for investment, while others place greater emphasis on investor tax planning, HMRC compliance or managing the ongoing requirements that follow a share issue.
