The Fund will invest in 5 to 10 companies, aiming to exit all of them within 4 years and targeting a return of 1.5x after fees*, excluding any tax reliefs and fees.

Reasons to invest


Investors will pay no Annual Management Charge for the management of this fund

Track record

To date we have invested c.£25m into AIM listed businesses which have provided a total return of £41m (£25m cash realised and £16m unrealised as at Sept 2021)

Shorter investment horizon

The strategy for the AIM EIS Fund looks to take advantage of the liquidity shortly after expiry of the 3-year EIS qualification period, which should enable investors to recycle their investments and utilise the initial tax reliefs more effectively

Risks to consider

Risks to capital

There is a high risk of capital loss when investing in smaller companies. You may therefore get back less than you invest or no return at all

Tax treatment may change

Personal circumstances, rates of tax, tax benefits and allowances may change and therefore tax benefits are not guaranteed

Volatility and liquidity

Whilst it is possible to trade shares in AIM quoted companies, this is dependent upon there being willing buyers. Share prices may go down as well as up and investments in AIM companies are likely to be more volatile than those in the London Stock Exchange official list

The AIM EIS Fund is a new fund which was launched in September 2021. Given it is an EIS fund no exits have been achieved or are anticipated until 2024 at the earliest. We have therefore used our wider exit track record as a simulated performance for this fund. The above figures are based on the 22 AIM quoted businesses that our EIS Portfolio Service has invested and covers the whole period of investing including our initial exit in November 2015. Please note that Fees as described in the Information Memorandum may apply on any exits. Past performance is not a guide to future returns. Your capital is at risk, you may get back less than you invest.

How can I invest?

We recommend that you seek independent financial advice before you invest. Please make sure that you have fully read and understood the Information Memorandum and Terms and Conditions applicable to the AIM EIS Fund product.

Alternatively, please speak to our Client Relations team for more information.

Further information

When you Subscribe to the Fund, your Subscription will be held in cash by the Custodian, helping build a sum of money for the Fund to invest (an “investment tranche”). Periodically, we will complete what is known as a “soft close” so that we can start making investments for all those investors who are included in that “investment tranche”. The timing of these “soft closes” will be designed to ensure efficient investment of investors’ money. Once your Subscription is included in an “investment tranche”, we will begin buying shares on your behalf.


The Fund will remain open for further Subscriptions which will build to form the next “investment tranche” until the £5 million fundraise has been achieved.

The minimum initial investment is £20,000

For any additional investments the minimum amount is £5,000

We have designed our AIM EIS Fund to appeal to investors’ who are looking to invest in UK SMEs with the aim of achieving capital growth over the shorter to medium-term (four years) in an investment that qualifies for the tax reliefs available under the Enterprise Investment Scheme.


They will be a High Net Worth Investor (as defined by the FCA) and will have experience of investing in tax advantaged investments (e.g. EIS, VCT) or buying shares in FTSE 100, FTSE 250, smaller quoted (e.g. the Aquis Stock Exchange), AIM or unquoted companies.


Those investors’ will understand what factors drive the movement of share prices and how in turn that impacts the value of their investment. They will also understand and accept the risks associated with making an investment in the Fund. Their current financial situation will mean that they do not need access to the amount they invest for at least five years or need an income from it. They should also be able to withstand the loss of some or all of that amount.


You should not invest in this Fund if you lack the requisite knowledge and experience, are looking to invest for less than four years, need your investment to pay an income or are risk averse or have a low tolerance to risk.

As at 28th May 2021, we had invested more than £24 million in AIM quoted companies in 22 AIM listed businesses, either at their Initial Public Offering (IPO) or in a subsequent fundraise. To date we have realised £23.6 million of cash returns for our investors, in addition to a further £19.1 million of unrealised investments. The total of £42.7m represents a combined return of £1.78 per £1 invested before charges and any tax reliefs.**
