The VAT Domestic Reverse Charge for Construction, Explained

What the reverse charge is

The VAT domestic reverse charge for construction services changed how VAT is handled between construction businesses. Instead of a subcontractor charging VAT and paying it to HMRC, the customer accounts for the VAT themselves. The subcontractor invoices without adding VAT, and notes that the reverse charge applies.

It was introduced to stop "missing trader" fraud, where a supplier charged VAT, was paid it, and then disappeared without passing it to HMRC. By moving the VAT accounting to the customer, that gap closes.

For everyone actually running a construction business, the practical effect is simpler than the theory: on a lot of your business-to-business invoices, you stop charging VAT — and that has a real impact on cash flow.

When it applies

The reverse charge applies when all of these are true:

• The supply is of construction services (and any materials supplied with them) that fall within CIS
• Both parties are VAT-registered
• Both parties are registered under CIS
• The supply is standard-rated or reduced-rated for VAT
• The customer is not an end user (see below)

In plain terms: it's for business-to-business construction work within the supply chain — a subcontractor billing a contractor above them.

The end-user exception

This is the part that trips people up. The reverse charge does not apply when your customer is an end user — someone who receives the construction services but doesn't sell them on as a construction service. The most obvious end users are:

• Domestic customers (homeowners) — normal VAT rules apply, you charge VAT as usual
• Businesses that use the building themselves (e.g. a shop owner having their premises refurbished)

End users should tell you in writing that they're an end user. If they do, you charge VAT normally. If a business customer is part of the construction supply chain and hasn't given you end-user notification, the reverse charge generally applies.

A useful mental model: if you're a subcontractor billing a contractor who will bill someone else for the same work, reverse charge. If you're billing the person who'll actually use the building, charge VAT.

What a reverse charge invoice looks like

Your invoice should:

• Show all the usual detail (your VAT number, a clear description, the net amount)
• Not add VAT to the total
• State the VAT rate that would have applied and the amount, for the customer's records
• Include wording making clear the reverse charge applies and that the customer must account for the VAT — for example, "Reverse charge: customer to account for VAT to HMRC."

Your customer then records both the output and input VAT on their own return, which usually nets to nil for them.

The cash-flow catch nobody warns you about

Before the reverse charge, subcontractors collected VAT on their invoices and held that cash until their VAT return was due — an informal, interest-free cash-flow cushion. Under the reverse charge, that cushion disappears: you're no longer collecting VAT you get to sit on for a few weeks.

For subcontractors doing mostly B2B work, this can be a genuine squeeze, and some find they move from paying VAT to HMRC each quarter to routinely reclaiming it (because they still pay VAT on their own purchases but no longer collect it on sales). If that's you, it may be worth moving to monthly VAT returns to get those repayments back faster.

Common mistakes

• Charging VAT when you shouldn't — the most frequent error, and it means your customer has paid VAT they'll struggle to reclaim.
• Applying the reverse charge to an end user — equally wrong in the other direction.
• Not getting end-user status in writing — leaving you to guess, and carry the risk.
• Invoice wording missing — the customer needs to know clearly that they're accounting for the VAT.

How ScopeKit helps

Because ScopeKit is built for UK construction, reverse-charge handling is part of the quoting and invoicing flow rather than an afterthought — so B2B invoices are produced with the right treatment and wording, and the end-user question is prompted rather than forgotten. Getting the VAT position right at quote and invoice stage is far cheaper than unpicking it after the customer has queried a VAT amount that shouldn't be there.
