- Nuvo Audit Limited
- Audit opinion
- Unqualified (clean)
- Going concern
- Affirmed
“At the time of approving the financial statements, the directors have a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future. Thus the directors continue to adopt the going concern basis of accounting in preparing the financial statements.”
Significant events
- “Direct comparisons with the previous financial period (17 months to 31st December 2024) are not entirely like for like due to the operational change of year end from July to December.”
- “Strong performance has enabled continued reinvestment in key areas, including IT infrastructure, website enhancements and bespoke software development to improve frontline user accessibility, process accuracy, reporting and overall operational efficiency.”
- “The forthcoming Martyn's Law (Terrorism Protection of Premises) Act 2025 will create operational adjustments across the industry, Constant Security Services welcome this development as it aligns with our ongoing focus on compliance and risk mitigation.”
- “Other areas of risk include predatory market pricing, the growth of unregulated operators and rising cyber security threats in light of the forthcoming Cyber Security Bill.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. Periods don't have to be exactly 12 months apart — a long or short period (typical around incorporation or year-end changes) will distort the comparison. Lines a company doesn't report are omitted. About these numbers
