Crowdstacker

Crowdstacker Ltd is a UK-based loan-based crowdfunding (peer-to-peer lending) platform, directly authorised and regulated by the Financial Conduct Authority (FCA), FRN 648742 [1]. The platform matches lenders with British businesses and offers loans, bonds and loan notes that can be held in an Innovative Finance ISA (IFISA) or via a P2P SIPP where appropriate [1][2][3].

So what this means for an investor: FCA authorisation means Crowdstacker is subject to FCA rules on governance, conduct and client money arrangements, but it does not make P2P investments safe — lenders can and do lose capital when borrowers default. The firm also holds permission to hold client money (it took over custody from an independent custodian in 2017), which affects how uninvested cash is treated before it is lent [1].

Crowdstacker operates as a loan-based crowdfunding platform that lists finance opportunities (often called "stacks") where individual investors can lend to UK businesses via loan notes, bonds or P2P loans [2][3]. Minimum investment is £100, and investors can choose to hold eligible products inside an IFISA or invest via approved SIPPs [2][3]. The platform states it does not charge investors for opening accounts, investing or transferring ISAs; fees are charged to borrowers instead [2][3].

So what this means: Low minimums and no investor fees lower the entry barrier, but the absence of investor fees does not reduce credit risk — losses are driven by borrower defaults and recoveries, not platform fees. The platform runs a secondary market that matches sellers and buyers to enable transfers of existing investments, but this is match-based and liquidity is not guaranteed [2].

Products: P2P business loans, loan notes and bonds, and an IFISA wrapper for eligible products [2][3]. The platform's website reports £82.76m raised and £59.28m repaid to date (platform figure) [3].

Fees: Crowdstacker states it charges no fees to investors for opening accounts, investing or transferring ISAs; fees are applied to borrowers [2][3]. Specific borrower fee schedules should be checked in the loan documentation.

Historic performance and defaults: Crowdstacker publishes historical actual and estimated returns by loan type and origination year. The supplied data shows wide variation: Property Development Loans (PDLs) reported an average return of 14.7% for 2023 (platform figure), while business loans have recorded both positive years (e.g. 2015, 2020–2021) and very negative actual annual returns including large losses in 2016–2017 and 2022–2023 [2].

So what this means: Historical high headline returns from PDLs may look attractive, but the business-loan track record includes years of severe capital impairment. Treat published return figures as backwards-looking and review cohort-level default and recovery data before allocating capital.

Crowdstacker is aimed at retail and professional investors willing to accept high risk in exchange for potentially higher interest rates from lending to SMEs and property development projects. The platform's own risk warning is explicit: "Don't invest unless you're prepared to lose money. This is a high risk investment. You may not be able to access your money easily and are unlikely to be protected if something goes wrong" [3].

So what this means: Only investors who understand credit risk, limited liquidity and the possibility of total loss should consider using the platform. Holding investments in an IFISA or SIPP can provide tax benefits, but does not protect capital from borrower default.

Strengths (substantiated):

• Direct FCA authorisation (FRN 648742) including permission to operate loan-based crowdfunding and to hold client money [1].
• No investor-facing fees for account opening, investing or ISA transfers (platform-stated) [2][3].
• Minimum investment of £100 increases accessibility for retail investors [2].

Risks (substantiated):

• Credit risk: borrower defaults have produced significant investor losses in some cohorts; published actual and estimated default and loss figures show severe losses in some business-loan vintages and high lifetime bad-debt percentages for specific origination years [2].
• Limited liquidity: the secondary market is match-based and does not guarantee quick sales or full recovery of capital [2]. Investor complaints raise withdrawal/processing delays [4].
• No FSCS cover for invested capital: once funds are lent to borrowers they are not covered by the Financial Services Compensation Scheme [1][3].

So what this means: Regulatory authorisation reduces some operational risks, but it does not remove credit or liquidity risk. Prospective investors must assess borrower-level security, covenants, enforcement history and platform vintage performance before investing.

Verified red flags and watch points:

• Investor complaints and losses: Independent reviews and complaints (including cases referred to the Financial Ombudsman Service) document investor losses following borrower defaults. Specific borrower failures such as BurningNight and Amicus have been cited by investors as leading to material losses; administrators in some cases indicated limited recoveries for lenders [4]. In several FOS decisions reviewed, the Ombudsman concluded losses were a product of credit risk and administrator actions rather than platform misconduct [4][1].
• Poor sentiment on review sites: Trustpilot and community threads show predominantly negative investor sentiment and reports of capital loss and slow complaint resolution [4].

Unresolved items: precise founder details, exact founding date and some borrower fee percentages quoted historically are not confirmed in the available research and are marked unverified.

So what this means: Negative investor outcomes are documented; however, FOS decisions in several cases have found losses were due to investment risk rather than regulatory breaches by Crowdstacker. Investors therefore face real capital risk and limited recourse in many default situations.
