Mastering the VAT Domestic Reverse Charge for Construction

The DRC moves VAT accounting from supplier to customer for in-scope construction services. The mechanics are simple in principle, fraught in practice — particularly around end-users, mixed contracts, and design-and-build.

The Domestic Reverse Charge for construction services has been live since 1 March 2021, and four years in, it remains the single largest source of VAT errors in the UK construction sector. The principle is straightforward: for B2B construction supplies within the CIS scope, the customer accounts for the VAT (rather than the supplier charging it). The practice involves a series of edge cases around end-user status, mixed-purpose contracts, scaffolding hire, design-and-build, and the interaction with the 5% disregard rule.

This guide covers the DRC end to end for principal contractors and subcontractors. The end-user certificate process. The specific edge cases (scaffolding, mixed contracts, professional services). Reconciliation in cloud accounting. And the cash-flow planning for businesses transitioning into or out of DRC scope.

End-user certificates must be in writing and held on file

A subcontractor invoicing an end-user (the customer who is not on-supplying the construction services) charges VAT in the normal way. Without a valid written end-user certificate, the supply defaults to DRC and the supplier should not charge VAT. Charging VAT incorrectly creates input tax disputes with HMRC for the recipient.

When DRC applies and when it does not

DRC applies when ALL of the following are true:

  1. 1The supply is between two VAT-registered businesses.
  2. 2The services are within the scope of CIS (most construction operations).
  3. 3The customer is registered for CIS (i.e., a contractor or deemed contractor).
  4. 4The customer is not an end-user.

DRC does NOT apply when any of the following is true:

  • The customer is an end-user (the building owner who will occupy or use the building).
  • The customer is the consumer (a private individual having work done at home).
  • The supplier is not VAT-registered.
  • The services are outside CIS scope (architectural design alone, certain professional services).
  • Zero-rated supplies (new build housing under specific conditions).
  • Supplies between connected parties in some circumstances.

End-user certificates and intermediary suppliers

An end-user certificate is the customer's written confirmation that they are the end-user (the building owner or otherwise the final consumer of the construction services). Once issued, the supplier must charge VAT in the normal way; DRC does not apply.

Common situations where the certificate matters:

  • A property developer being the end-user for a new build before sale: DRC does not apply for purchases.
  • A retailer being the end-user for fit-out works at its own stores: DRC does not apply.
  • An intermediary supplier (a contractor on-supplying to another contractor) does not issue end-user certificates because they are not end-users themselves.
  • A property investor having maintenance work done on a held-to-let property: typically end-user, certificate appropriate.

Mixed contracts and the 5% disregard

Where a single contract includes both DRC and non-DRC supplies (for example, design plus construction services), HMRC permits a 5% disregard rule: if the non-DRC component is 5% or less of the total contract value, the entire contract can be treated as DRC. This simplifies invoicing for predominantly-DRC contracts that include small amounts of out-of-scope work.

Where the non-DRC component exceeds 5%, the contract has to be split: DRC applies to the in-scope portion, normal VAT to the out-of-scope portion. The split must be defensible from contract documents and pricing schedules.

Scaffolding: hire vs erection

Scaffolding contracts split at hire vs erection. Pure hire (the customer arranges erection separately) is outside CIS and outside DRC; the scaffolding hire is a normal VAT-charged supply. Combined hire-and-erection (the contractor erects, dismantles, and bills as a single service) falls within CIS and DRC. Many scaffolding subcontractors invoice these as combined services without realising the DRC implications.

The cash-flow impact of DRC

For a subcontractor accustomed to charging VAT and holding it before remitting to HMRC, transitioning into DRC scope eliminates that float. Where VAT was £20,000 per month of working capital, that capital disappears overnight. The mitigation strategies:

  1. 1Move from quarterly to monthly VAT returns to stabilise input tax recovery.
  2. 2Use the Annual Accounting Scheme where eligible to spread the impact.
  3. 3Tighten payment terms to align with the new cash-flow profile.
  4. 4Negotiate retention bond facilities with banks to bridge the working capital gap.
  5. 5Where the business mainly supplies to end-users (with end-user certificates), the impact is minimal — DRC does not apply.

Reconciling DRC in cloud accounting

Modern accounting software (Xero, QuickBooks, Sage) supports DRC tax codes. The setup:

  • For supplies subject to DRC: use the "Reverse Charge - 20% (or 5%)" tax rate. Net amount on the invoice; "VAT will be accounted for under reverse charge" annotation.
  • For purchases subject to DRC: same tax rate applied. Software automatically calculates output and input VAT, both posting to the appropriate VAT return boxes.
  • On the VAT return: DRC outputs go in Box 1, DRC inputs in Box 4, with no impact on Box 6 or Box 7. The software handles this if the tax codes are correctly assigned.
