Trustee OS for the United Kingdom
The operating system for the insolvency practitioner.
Built on the Insolvency Act 1986 and the Insolvency (England and Wales) Rules 2016.
The framework
Five procedures.
Administration (Sch B1)
The administrator pursues the paragraph 3 objectives; appointment lasts one year unless extended.
Company voluntary arrangement (Part I)
The IP acts as nominee, then supervisor.
Standalone moratorium (Part A1)
The IP acts as monitor.
Liquidation (Part IV)
CVL, MVL and compulsory winding-up.
Restructuring plan (Companies Act 2006, Part 26A)
Cross-class cram down under s901G.
The role
What the insolvency practitioner has to do.
- 01
Hold a licence under s390 and s390A from ICAEW, IPA or ICAS.
- 02
Obtain and verify the statement of affairs (Sch B1 paras 47–48).
- 03
File proposals within eight weeks (para 49) — failure is an offence.
- 04
Admit or reject every proof of debt with written reasons (IR 2016 rr 14.3, 14.4, 14.7), against a 21-day appeal window (r 14.8).
- 05
File progress reports every six months in administration (r 18.6) and every twelve months in liquidation (rr 18.7–18.8), including remuneration and any fee-estimate overrun (r 18.4).
- 06
Pay estate funds into the Insolvency Services Account.
- 07
Close with a final account (r 18.14).
The rules are prescriptive. The reconciliation behind them is still manual.

Insolvency Service, calendar year 2025 and practitioner regulation review, January 2026.
Why now, specifically
Bond wording, fee estimates and rising complaints.
From 1 January 2026 every insolvency bond must use Secretary of State-approved wording, with the general penalty sum tripled from £250,000 to £750,000 — the first change since 1986.
In force since 22 June 2026, SI 2026/561 requires committee or creditor approval to exceed a fee estimate, and removes fax as a method of delivery. Complaints through the Insolvency Service gateway rose 47% in a single year, to 966. The compliance surface is growing while the fee is not.
