The decisive strategic agenda is capacity restoration, capital redeployment, and succession planning — each addressable, none deferrable.","website":"https://www.plextek.com/","links":{"page":"https://www.companiesintheuk.co.uk/ltd/plextek","people":"https://www.companiesintheuk.co.uk/company/plextek/people","filing_history":"https://www.companiesintheuk.co.uk/company/plextek/filing-history","companies_house":"https://find-and-update.company-information.service.gov.uk/company/02305889","financials":"https://www.companiesintheuk.co.uk/company/plextek/financial","control":"https://www.companiesintheuk.co.uk/company/plextek/control","charges":"https://www.companiesintheuk.co.uk/company/plextek/charges","ai_analysis":"https://www.companiesintheuk.co.uk/company/plextek/analysis"},"source":"CompaniesInTheUK, from Companies House, The Gazette and other public registers (see /support/about).
