What happened
ISG LIMITED (company number 10081578), incorporated in 2016, entered creditors' voluntary liquidation on 30 October 2024. Its status at Companies House is now: liquidation.
Why it failed
Loss-making high-rise contracts, Covid, inflation, stalled major projects and tighter bonding strained liquidity, and attempts to sell Fit Out or recapitalise the group failed before the September 2024 administrations.
- Main reason: Losses on contracts
- Covid-19
- Cost inflation
- Clients not paying or failing
- Delays
- Funding withdrawn
- HMRC debts
- Sale or investment failed
- Cash flow
- Group company failed
Our summary of the reasons given in the administrators' proposals for ISG Construction, another company in the group. These record the administrators' and directors' account of what happened.
The directors and shareholders decide to close an insolvent company. A liquidator sells its assets and shares the proceeds among creditors.
Previously known as: ISG PLC, CATHEXIS UK HOLDINGS II PLC, ISG GROUP PLC.

Key figures
- Owed to unsecured creditors (estimated), as at 20 September 2024
- £885.0m
- of which trade creditors £308.3m. HMRC owed £89.4m. staff owed £6.3m. Expected return to unsecured creditors: none expected
- Administrators' proposals for ISG Construction Ltd and other group companies
The last accounts filed were group accounts made up to 31 December 2022, 22 months before it failed. Private companies have nine months after their year end to file, so a gap of more than 21 months usually means the next accounts were overdue, one of the warning signs worth checking for.
The full filing history, including any late filings, charges and director changes, is on Companies House.
