Investment infrastructure for energy and impact
Community energy, green bonds and natural capital investments have specific requirements that general-purpose technology doesn’t address. ShareIn provides the complete investment platform infrastructure — from investor onboarding through to interest payments and portfolio reporting — so platform operators can focus on their projects, their investors and their impact.
We handle community share offers with minimum and maximum raise targets and timed offer windows. We process interest payments on per-project schedules that run for the life of the asset. We wrap eligible investments in ISAs so your investors earn tax-free returns. And we hold client money in segregated, CASS-compliant accounts.
Whether you’re launching a new platform, expanding an existing one, or looking to add ISA management and client money handling to your current offering — the infrastructure is already built, already regulated, and already powering the platforms your investors will recognise.
A complete platform for energy and impact investment
ISA-wrapped green investments
ShareIn has been an HMRC-authorised ISA Manager since 2016 — wrapping community energy bonds and lending products in Innovative Finance ISAs so your investors earn tax-free returns. ISA transfers in and out, annual HMRC returns, subscription tracking across tax years, and the specific record-keeping obligations that come with being a plan manager. We’ve been doing this for a decade.
Segregated client money
Investor funds sit in segregated client money accounts held under ShareIn’s FCA permissions. CASS compliance, FSCS protection, daily reconciliation, automated pay-in and payout processing. Investor wallets let funds deploy across multiple project investments without repeated bank transfers. If you hold client money on your own permissions, we can connect to your named account and handle the CASS reporting. If you’d rather use ours, that’s included.
Bond and share offer management
List offers with minimum and maximum targets, allocation rules and timed offer windows. Process interest payments and capital returns automatically on per-project schedules — whether that’s semi-annual interest on a 20-year wind farm bond or a community share withdrawal after 3 years. Manage multiple live offers from a single admin dashboard.
Branded investor portal
Your investors log in to your platform, on your domain, with your design. Portfolio dashboard, project updates, documents, investment history — all in one place. An investor with holdings across six different projects sees everything in a single view.
Onboarding, KYC and compliance
Integrated identity verification, appropriateness assessments, risk warnings and cooling-off periods built to the FCA’s current requirements. Updated when those requirements change.
