Bridging SEIS/EIS Startups and Companies House integration
Welcome to the definitive guide on Companies House integration for 2026. If you run a SEIS or EIS startup, you face a mountain of filings, identity checks and shareholder data to manage.

With a platform like Oriel IPO, you can centralise everything from director verification to People with Significant Control records. Revolutionise your Companies House integration and stay compliant without the guesswork.
In this post we unpack the 2026 updates, share step-by-step instructions for integrating your systems, and show how Oriel IPO’s commission-free subscription model helps you manage SEIS/EIS compliance. We cover officer IDV, PSC transparency, bulk monitoring, automated filings and best practices. You’ll learn how to plug Companies House data directly into your workflows, reduce errors and speed up due diligence. Whether you’re a founder, investor or accountant, this guide will bring clarity to Companies House integration for your SEIS/EIS journey.
Why the 2026 Companies House update matters
The 2026 changes under the Economic Crime and Corporate Transparency Act bring fresh requirements to every startup in the UK. From 18 November 2025, all new directors and people with significant control must complete mandatory identity verification before appointment. Existing officers get until 17 November 2026 to comply or risk blocking confirmation statements. The register now also acts as the sole official source for directors, secretaries and PSCs, cutting out past inconsistencies between internal and public records.
At the same time, digital incorporation fees have risen to £100 and confirmation statement filings now cost £50. For SEIS/EIS startups, missing a fee or ID verification deadline can jeopardise valuable tax relief for investors. That’s why a reliable Companies House integration is critical. You need tools that automatically check IDV status, flag unverified officers and push filings on time. Manual uploads and PDF downloads won’t cut it once you scale.
Step-by-step guide to Companies House integration for SEIS/EIS startups
Navigating filings and verification is easier when you break it down. Follow these four steps to set up a robust integration between your systems and Companies House.
Step 1: Understand officer identity verification
The new IDV field on each officer record now indicates if someone has completed the mandatory check. Before you onboard new directors, verify their status to avoid blocked filings. You can access IDV status via the Companies House REST API or through Oriel IPO’s dashboard, where alerts highlight pending verifications.
Key actions:
– Query officer records for the “identity verification status” flag
– Set triggers to remind directors to complete ID checks
– Log verification timestamps in your compliance ledger
Step 2: Map your PSC data
The People with Significant Control register remains fully public, but it now sits on a single, unified platform. A PSC is anyone holding at least 25 per cent of shares or significant influence. However, company-level PSC disclosures do not always capture underlying UBOs. Use your integration to:
– Download confirmation statements to extract shareholder percentages
– Cross-reference PSC entries with UBO searches in Oriel IPO Hub
– Alert your adviser network when a next-level loophole appears
Step 3: Automate filings and downloads
No one enjoys manual PDF downloads. With the streaming API, you can push new filings straight into your system in near real time. For volume checks or multi-jurisdiction verifications, plug in Oriel IPO’s single-point API to gather data from Companies House plus 300+ global registries.
Bullet list for automation:
– Connect your CRM or equity management tool to the REST API
– Schedule nightly pulls of filing history
– Use webhooks to capture director changes and new PSC entries
– Archive every event in a searchable datastore
Once set up, you’ll never miss a DS01 strike-off application or a new charge. You also unlock automated alerts for fee changes, so you can budget ahead for the £50 confirmation statements.

– Officer appointments and resignations
– PSC updates and new beneficial owner entries
– Insolvency events and charge registrations
Oriel IPO users can add unlimited companies to their watchlist and receive digest emails when anything changes. You’ll also gain insights into filing patterns, common errors and identity verification delays.
