Gooch & Housego Lands Fresh NatWest Funding

Somerset photonics engineering specialist Gooch & Housego has secured fresh funding from NatWest, taking the bank’s total backing of the Ilminster-based firm past £50m. Announced on 18 May 2026, the new commitment will fund inventory of critical materials including germanium, expanded manufacturing capacity and supply chain resilience as the company scales to meet rising demand from aerospace, defence, semiconductor and life sciences customers. It is the latest tranche in a sustained banking relationship.

Founded in 1948, Gooch & Housego designs and manufactures optical systems and advanced photonic components, with capabilities including growing high-purity crystals in-house and polishing glass to near-atomic smoothness. The company employs close to 1,000 people across its UK and US sites. The new funding will support the expansion of manufacturing facilities at Ilminster and bring more optical lens production in-house, alongside building strategic inventory of critical raw materials such as germanium, which has become harder to source globally amid tightening export controls on semiconductor-relevant materials.

Charlie Peppiatt, chief executive at Gooch & Housego, said the investment is a key enabler for continued growth and innovation, with increased inventory and expanded capacity allowing the company to strengthen its supply chain and meet demand from customers in mission-critical sectors. Stuart Allison, relationship director at NatWest, said the bank’s increased commitment reflects Gooch & Housego’s leadership in photonics engineering and its focus on supply chain resilience and advanced manufacturing. The deal sits within a sustained pattern of UK bank support for precision manufacturing capacity in defence-relevant supply chains.

The capital allocation signal is striking: photonics is now treated as critical national infrastructure in the same conversation as semiconductors and defence electronics. With life sciences instrumentation included in Gooch & Housego’s stated demand mix, watch for further onshoring of precision optics capability across the UK as imaging, diagnostics and laser-based therapeutics manufacturers tighten their own component sourcing strategies.
