“The company has prepared a cash flow forecast projecting forward to the end of July 2026. The business demonstrated continued growth during 2024, resulting in increased retained earnings providing stability and giving the directors reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future.”
Significant events
- “The group will continue to offer a circular economy of the goods it produces by having the company's B2D - "Back 2 Diam" - service of returning end-of-life products back to the business from customers and recycling and re-using the components to produce new products for customers.”
- “In January 2025, company experienced flooding of the Loughborough site. Minimal damage was caused and there was no impact to the balance sheet after the year end.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
