Pure Capture Innovations Secures Seed Funding to Tackle Water Micropollutants

Oxford-based CleanTech startup Pure Capture Innovations Ltd has closed a seed funding round of £93.5k. The transaction, finalised on 23 March 2026, values the environmental services company at an estimated £2m post-money.

Incorporated in August 2025, Pure Capture Innovations operates out of Oxford with a lean team of two employees. The company focuses on water purification technology, specifically addressing the growing environmental and public health crisis of micropollutants. Pure Capture Innovations licenses sustainable adsorbent materials designed to extract harmful substances from water systems. These targets include short-chain PFAS (per- and polyfluoroalkyl substances), pesticides, pharmaceuticals, and industrial dyes.

PFAS are notoriously difficult to break down and have been linked to various health issues, prompting stricter government regulations globally. This regulatory shift is forcing industrial production markets to seek out new technical designs and chemical innovations for water treatment at the source. A key differentiator for Pure Capture Innovations is its dual-action approach. The proprietary materials capture carbon while simultaneously cleaning water. Furthermore, the company states that its adsorbent materials can be repurposed at the end of their lifecycle, aligning with circular economy principles. As a recently established entity, revenue and profit figures are not yet publicly available.

The current seed round brings £93.5k of fresh capital into the business. The allotment and filing dates both occurred on 23 March 2026. This capital injection gives the company an estimated post-money valuation of £2m. Specific investors participating in this round have not been publicly disclosed. As this is the first major funding event since the company was incorporated seven months ago, there are no previous rounds for comparison.

The investment in Pure Capture Innovations aligns with a broader surge in UK climate tech and water purification funding. The UK climate tech sector received £15.5bn in investment between 2020 and 2024, according to a March 2026 report by Barclays and Sustainable Ventures. While 66 percent of that funding in 2024 was concentrated in London, Oxford remains a critical hub for deep tech and environmental innovation.

Furthermore, water technology is attracting significant capital, driven by the aforementioned regulatory pressures and environmental concerns. The UK water regulator's Ofwat Innovation Fund is currently deploying £600m between 2020 and 2030 to support new technologies. Startups addressing forever chemicals have seen particularly strong investor appetite recently, as demonstrated by other UK-based materials science firms raising multi-million-pound rounds to scale similar removal systems. This £93.5k seed round provides Pure Capture Innovations with the initial runway to further its scientific research and material development in this highly active sector.
