A subcontractor preparing an invoice needs to know whether to collect VAT or leave the customer to account for it. The construction services reverse charge can change that decision, even when the work itself attracts VAT. Getting the treatment right starts with the contract, the customer’s status and the type of service supplied.
The rules took effect on 1 March 2021. They are established requirements, rather than a new measure introduced for 2026.
Key Points
- The customer accounts for VAT on qualifying supplies.
- The supplier must be VAT-registered in the UK, and the customer must be registered for UK VAT or required to be registered. The payment must also be reportable under CIS.
- Standard-rated and reduced-rated services can qualify; zero-rated work does not.
- A reverse charge invoice is not a zero-rated invoice.
When Does The Construction Services Reverse Charge Apply?
The reverse charge applies to qualifying construction supplies when the supplier and customer meet the relevant VAT and CIS conditions. VAT registration alone is insufficient.
Before invoicing, check the following conditions for applying the reverse charge:
- Both businesses are registered for UK VAT.
- The payment is reportable under the Construction Industry Scheme.
- The work is a specified construction service attracting standard-rate or reduced-rate VAT.
- The supplier is not an employment business supplying staff or workers..
- The customer has not provided written confirmation of end-user or qualifying intermediary-supplier status.
Keep the customer’s VAT details and relevant confirmations with the contract. Agreeing on the treatment before work begins helps prevent disputes when payment becomes due.
Which Construction VAT Services Are Covered?
Covered services include many building, installation, repair and finishing activities. However, some professional services and standalone supplies fall outside the construction reverse charge.
HMRC’s list of construction services includes:
- Manufacturing or delivering building components, equipment, materials, plant or machinery to the site.
- Manufacturing or delivering components for heating, lighting, air-conditioning, ventilation, power, drainage, sanitation, water or fire-protection systems.
- Certain consultancy services, including building, engineering, interior or exterior decoration and landscape consultancy.
- Signwriting and erecting or repairing signboards and advertisements.
- Installing seating, blinds and shutters.
- Installing security systems, including burglar alarms, CCTV and public-address systems.
- Purely artistic works such as sculptures and murals.
Standalone architectural or surveying services and delivery-only supplies of building materials are excluded. Check the whole contract where several activities are combined, rather than deciding solely on the basis of a trade description.
How Does End-User Status Affect VAT Treatment?
An end user receives construction services without making an onwards supply of those services. The reverse charge does not apply where the customer is an end user or qualifying intermediary supplier and has notified the supplier in writing of that status. An end user generally receives the construction services for its own use rather than making an onwards supply of those services.
A business commissioning work on its premises may qualify, depending on its circumstances. However, a contractor supplying building work onwards to a homeowner is not automatically an end user simply because the homeowner is a private customer.
The written notification can be included in an email or contract. Keep it with the project records and identify the supplies it covers.
Practical checks should therefore cover who receives the work, whether they resupply it and what they have confirmed in writing. A customer’s company name or property ownership alone does not settle the issue.
How Do CIS Reverse Charge VAT and Tax Deductions Differ?
The VAT domestic reverse charge determines who accounts for VAT. CIS deductions are advance payments towards the subcontractor’s tax, so the two calculations must be considered separately.
For subcontractors providing plumbing, heating or gas installation work, first check whether the contract falls within the Construction Industry Scheme. Working directly for a private householder is different from subcontracting to a construction contractor. Subcontractor registration is not compulsory, but remaining unregistered normally leads to higher deductions.
Under the usual CIS payment rules, deductions are 20% for registered subcontractors and 30% for unregistered subcontractors. Businesses with gross payment status receive payment without CIS deductions. VAT is excluded from the amount subject to CIS deduction. Direct material costs paid for by the subcontractor may also be deducted, subject to the CIS rules.
The recovery route depends on the business structure:
- Sole traders and individual partners: report CIS deductions through self-assessment.
- Limited companies: report deductions suffered through an Employer Payment Summary and offset them against relevant payroll liabilities.
Limited companies must not reclaim these deductions through their corporation tax return. HMRC sets out the separate CIS deduction recovery procedures.
Construction companies and contractors operating through limited companies can manage their separate profit-tax obligations through our corporation tax services.
What Does A VAT Reverse Charge Construction Example Look Like?
The supplier invoices the net contract amount, while the customer calculates and records the VAT. This VAT reverse charge example assumes both parties qualify, the customer can recover all input VAT and the subcontractor has gross payment status under CIS.
A subcontractor completes standard-rated electrical installation work for £8,000, including related materials. Applying the standard VAT rate of 20% gives a reverse charge VAT of £1,600.
| Item | Amount Or Treatment |
| Net value of work and materials | £8,000 |
| VAT accounted for by the customer | £1,600 |
| Amount paid to the subcontractor | £8,000 |
| Customer’s output VAT entry | £1,600 |
| Customer’s input VAT recovery, assuming full entitlement | £1,600 |
The matching VAT entries produce no net VAT cost for this customer. Recovery may be restricted in other circumstances, so that result should not be assumed for every business.
What Should The Invoice And VAT Return Show?
The invoice must identify the reverse charge, while the VAT return must record the transaction in the appropriate boxes. Use a dedicated reverse charge tax code rather than treating the sale as zero-rated.
Alongside normal invoice information, show the VAT amount the customer must account for or the rate if the amount cannot be shown. Exclude that VAT from the amount payable to the supplier. Suitable wording is: “Reverse charge: customer must account for VAT of £1,600.”
For the example above, the entries are:
- Supplier: £8,000 in Box 6, with no output VAT for this sale in Box 1.
- Customer: £1,600 in Box 1, recoverable VAT in Box 4 and £8,000 in Box 7. Do not include this purchase in Box 6.
Box 6 and Box 7 are still completed in the normal way. The reverse charge changes where the VAT itself is reported, not whether the net values are included in Boxes 6 and 7. These entries combine the construction-specific treatment with HMRC’s VAT return box requirements.
| Party | Box 1 | Box 4 | Box 6 | Box 7 |
| Supplier | £0 output VAT for this supply | Not applicable to this sale | £8,000 | Not applicable |
| Customer | £1,600 | £1,600, subject to normal recovery rules | Not applicable for this purchase | £8,000 |
How Can Businesses Prepare For The Cash-Flow Impact?
Subcontractors should forecast receipts without the VAT they would otherwise collect. Where recoverable input VAT regularly exceeds output VAT, a business may become a repayment trader and may consider submitting VAT returns monthly, subject to the relevant rules and practical considerations.
A practical review should compare customer payment dates with wages, material purchases and expected VAT repayments. Build the forecast around actual contract terms rather than assuming every invoice will be paid promptly.
Check software settings using a sample sales and purchase invoice before the next return. Keep VAT, CIS deductions and outstanding customer balances separately identifiable so each figure can be reconciled.

FAQs About CIS Reverse Charge in the UK
Can I Charge 5% VAT On Construction Work?
First establish whether the work is standard-rated, reduced-rated or zero-rated under the normal VAT rules. If the work qualifies for 5% VAT and the reverse-charge conditions are also met, the customer accounts for VAT at 5%.
Does the reverse charge apply to labour only?
A labour-only subcontractor supplying qualifying construction operations can fall within the reverse charge. This scenario is different from an employment business supplying staff or workers, where the construction reverse charge does not apply.
Is reverse charge mandatory?
Yes, it is compulsory when the relevant conditions apply. Eligible end users and intermediary suppliers can notify their status in writing so normal VAT treatment applies.
Does the reverse charge cover materials?
Where materials are supplied with qualifying construction labour, the reverse charge normally applies to the whole supply, including the related materials. Materials supplied on their own, such as delivery-only supplies, are normally outside the construction reverse charge.
What are the VAT rules for UK construction work?
Construction work can attract standard, reduced or zero-rate VAT, depending on the supply and its conditions. Establish the correct rate first, then decide whether the customer must account for VAT through the reverse charge.
Can I use cash accounting for reverse charge transactions?
No, transactions subject to the domestic reverse charge are excluded from the VAT Cash Accounting Scheme. The business may continue using cash accounting for other eligible transactions, but reverse-charge transactions must be accounted for using the normal VAT tax-point rules.
