Top 4 platforms for your green IFISA

Written by Lori Campbell on 26th May 2023

Aside from Cash ISAs and Stocks and Shares ISAs, there’s a third way to invest any extra cash that is gaining in popularity – the Innovative Finance ISA (IFISA).

An IFISA is a type of ISA that allows you to include investments that have been made via crowdfunded bonds or peer-to-peer loans. Within the IFISAs on offer, there are sustainable options aplenty.

As with any ISA, you can invest up to £20,000 per year without paying any tax on your returns or interest. IFISAs arguably offer an option that sits somewhere between the reliability of cash, and the potentially higher returns from investment in the stock market (over the longer term).

However, IFISAs are riskier than cash savings and can vary dramatically so make sure you read the risk description of the one you are interested in carefully. Unlike mainstream ISAs, they are not covered by the Financial Services Compensation Scheme (FSCS). You can also check out the best platforms for a green stocks and shares ISA before you decide.

Here, we round up the top platforms for making your IFISA money green this year.


Good With Money ‘Good Egg’ Triodos has a crowdfunding platform that offers IFISA investments in a range of positive impact bonds. These enable you to invest directly in pioneering UK-based organisations that are delivering positive change.

All of the investment opportunities offered by Triodos are with organisations delivering positive environmental, cultural or social impact. This could be reducing plastic pollution, tackling inequality, protecting nature, or generating renewable energy – all with the aim of a financial return alongside helping to create a more sustainable world.

Tridoos is a B-Corp firm, which means it has been assessed against a number of strict criteria including social and environmental performance, public transparency, and legal accountability to balance profit and purpose.


Abundance, another Good With Money ‘Good Egg’ firm, is a trailblazing renewable energy platform where you can invest in a wide range of green and social infrastructure projects through your IFISA from a minimum of just £5 in each.

This lets you easily diversify your holdings within an Abundance IFISA across a range of sectors, investment terms and risk levels. Most of the projects available for investment offer six-monthly cash returns, which are paid straight into your Abundance IFISA account.

All its investments are direct; you choose the companies you fund, and you can see exactly how your money will be used to earn you a return. Abundance is also a B-Corp company.

The Abundance marketplace lets you buy into any of its past investments. Although you should look to invest for the long-term, you can also use the marketplace to sell your investment to another buyer if you need to get your money back earlier than expected.

Abundance is currently offering a five-year investment to help Lewisham Council reach net zero through sustainable transport projects. The Lewisham Climate Action 2028 is targeting returns of 4.3 per cent per year.

There is also an eight-year investment in plymouth-based EV charging firm Wenea with estimated returns of 8.2 per cent IRR*, and a 10-year investment in Carbon Plantations Norfolk to fund the planting of sustainable timber with targeted returns of eight per cent per year.
