If you want the full explanation of the legal closure routes, read our main guide on how to close a limited company in the UK. This page focuses on the construction-specific steps that usually sit alongside that process.
When a construction company can be closed
The right closure route depends on whether the company can pay its debts. If the company is solvent, the usual routes are strike-off or members’ voluntary liquidation (MVL). If it cannot pay its bills, you are usually looking at creditors’ voluntary liquidation (CVL), administration, or another insolvency route.
For a construction business, this matters because unpaid subcontractors, HMRC liabilities, hire purchase balances, retention disputes, or VAT/CIS arrears can make strike-off unsuitable. If there is any doubt, the directors should take professional advice before filing DS01.
Extra construction steps
Construction companies usually have a few issues that normal office-based businesses do not. Before closing, review all live contracts and make sure every subcontractor, supplier, and client account is reconciled.
The most common construction-specific tasks are:
- Finalise CIS returns and notify HMRC that the company has stopped operating under the scheme.
- Pay outstanding subcontractor invoices and settle any CIS deductions that still need to be paid to HMRC.
- Chase any retentions owed to the company and resolve any retentions the company is holding for others.
- Return hired plant and equipment, end hire agreements, and deal with finance or lease obligations.
- Cancel specialist insurance policies such as public liability, employers’ liability, and Contractors’ All Risks cover.
- Deal with trade accreditations or industry registrations that are linked to the business, such as certification or card-scheme memberships where relevant.
CIS and HMRC
If your company has operated under CIS, you must make sure all monthly returns are up to date before closure. HMRC says that when you stop using subcontractors completely, you must tell HMRC and stop filing monthly CIS reports. Any outstanding returns should still be filed, even if the company has ceased trading.
If the company acted as a CIS contractor, it is best to confirm the cessation date with HMRC and keep a written record of the notification. This helps reduce the risk of penalties or objections when you later apply to strike off the company. If the company is insolvent, the records and cessation process should be handled carefully because HMRC and creditors may have claims outstanding.
Retentions and final payments
Retentions are a common feature of construction contracts, usually held back until the defects liability period ends or certain milestones are met. Before closing, check whether your company is owed any retention money and whether you owe retention to others.
This is important because retentions can still come due after work has finished. If the company is struck off too early, unresolved money can become difficult to recover or distribute properly, and any remaining assets may pass to the Crown as bona vacantia. For that reason, directors should try to complete retention reconciliation before filing for dissolution.
Plant, tools, and other assets
Construction companies often hold valuable assets such as vehicles, tools, scaffolding, office equipment, or plant. Before closing, decide whether each item will be sold, returned, transferred, or used to settle liabilities. Any asset left in a dissolved company can pass to the Crown, so it is a mistake to assume that unused equipment can simply be left behind.
If there is hire purchase, leasing, or finance attached to equipment, review the contract terms before closing. You should also check whether any asset is personally owned by a director rather than the company, because that affects what can be distributed before dissolution.
Strike-off checklist
If the company is solvent and meets the strike-off conditions, you can usually apply to dissolve it through Companies House. The company must not have traded or sold stock in the last three months, must not have changed its name in the last three months, must not be threatened with liquidation, and must not have agreements with creditors such as a CVA.
A practical pre-filing checklist looks like this:
- Stop trading and finish all active jobs.
- Settle subcontractors, suppliers, payroll, VAT, Corporation Tax, and CIS matters.
- Cancel or close insurance, finance, and hire agreements.
- Deal with retentions, assets, and bank balances.
- File the DS01 application once the company is genuinely ready.
Insolvent construction companies
If the company cannot pay its bills, do not use strike-off as a shortcut. In that situation, creditors come first, and the business will usually need insolvency advice. In construction, this can include unpaid subcontractors, tax arrears, disputes over retentions, or unpaid hire and supply charges.
The right route may be CVL or another formal insolvency process, depending on the facts. That is why the main closure guide should be used first, and this page should be read as the construction-specific layer on top of it.
