The company earns a grade of C: not in distress, but its liquidity buffer now covers barely a fortnight of payroll, leaving it dependent on prompt debtor collections and continued group support. The FY2027 accounts will be the decisive test of whether this was a managed slim-down or the early stages of decline.","website":null,"links":{"page":"https://www.companiesintheuk.co.uk/ltd/rt-infrastructure-solutions","people":"https://www.companiesintheuk.co.uk/company/rt-infrastructure-solutions/people","filing_history":"https://www.companiesintheuk.co.uk/company/rt-infrastructure-solutions/filing-history","companies_house":"https://find-and-update.company-information.service.gov.uk/company/06903399","financials":"https://www.companiesintheuk.co.uk/company/rt-infrastructure-solutions/financial","control":"https://www.companiesintheuk.co.uk/company/rt-infrastructure-solutions/control","charges":"https://www.companiesintheuk.co.uk/company/rt-infrastructure-solutions/charges","ai_analysis":"https://www.companiesintheuk.co.uk/company/rt-infrastructure-solutions/analysis"},"source":"CompaniesInTheUK, from Companies House, The Gazette and other public registers (see /support/about).
