The VAT Domestic Reverse Charge for Construction: Explained Clearly

If you’re a contractor or subcontractor working in the building trade, the VAT Domestic Reverse Charge (DRC) is one of those rules that causes more head-scratching than almost any other.
The truth is, it doesn’t change how much VAT is ultimately due - it changes who pays it over to HMRC. But getting it wrong on your invoices can lead to errors, cash flow surprises, and unwanted attention from HMRC.
This guide continues our series of simple explainers designed to help you navigate the UK tax system with confidence. If you're a self-employed subcontractor, you may also find our guide to Self-Assessment for the Self-Employed useful — and, looking ahead, our explainer on Making Tax Digital for Income Tax Self-Assessment.
Below, we’ll break down what the reverse charge is, who it applies to, how it works in practice, and the common mistakes we see - so you can stay compliant and stress-free.
Let’s get into it 👇

💡 What Is the VAT Domestic Reverse Charge?
The VAT Domestic Reverse Charge is an anti-fraud measure introduced by HMRC on 1 March 2021. It applies to most supplies of building and construction services between VAT-registered businesses.
Normally, a supplier charges VAT on their invoice and pays it over to HMRC. Under the reverse charge, that responsibility flips:
The supplier (usually a subcontractor) no longer charges VAT on their invoice.
The customer (usually the contractor) accounts for the VAT directly on their own VAT Return instead.
In other words, the customer records both the output VAT and the input VAT on the same return. Where the VAT is fully recoverable, the two cancel each other out - so no cash actually changes hands for the VAT element.
The rule was designed to stamp out “missing trader” fraud, where a supplier charged VAT, collected it from the customer, and then disappeared without paying it to HMRC.
✅ When Does the Reverse Charge Apply?
The reverse charge applies when all of the following are true:
The work falls within the scope of the Construction Industry Scheme (CIS).
The supply is standard-rated (20%) or reduced-rated (5%) for VAT.
Both the supplier and the customer are VAT-registered.
Both the supplier and the customer are registered for CIS.
The customer is not an end user (and has not confirmed end user status - more on that below).
If any one of these conditions isn’t met, you simply apply the normal VAT rules.
🔧 What Counts as “Construction Services”?
The reverse charge follows the CIS definition of construction operations. This broadly includes:
General building, alterations, repairs and demolition
Groundworks and civil engineering
Electrical, plumbing, heating and air conditioning work
Painting and decorating the interior or exterior of a building
Materials supplied as part of the labour (these are included in the reverse charge)
🚫 What’s Excluded?
Some supplies are not caught by the reverse charge, including:
Professional services - architects, surveyors, and consultants
Zero-rated supplies, such as work on a qualifying new build
Employment businesses that simply supply staff (this is treated as a supply of workers, not construction services)
Supplies to end users and intermediary suppliers
👤 The “End User” Rule - Why It Matters
This is the part that trips people up most often.
An end user is a business or individual who receives construction services for their own use and does not sell those services on as part of another supply.
Common examples of end users include:
A homeowner having an extension built
A landlord carrying out works on their own property
A property developer or business using the works for itself
When your customer is an end user, the reverse charge does not apply - you charge VAT in the normal way.
Key point: The customer must tell you in writing if they are an end user. If they don’t notify you, and they’re both VAT and CIS registered, you should continue to apply the reverse charge. Don’t assume - always confirm status in writing.
🧮 How It Works in Practice
Seeing the numbers side by side makes the reverse charge far easier to grasp. Below are two simple worked examples.
📌 Example 1: Subcontractor Working for a Contractor (Reverse Charge Applies)
Dave is a VAT-registered, CIS-registered plumber. He carries out £8,000 of work for a main contractor who is also VAT and CIS-registered and is not an end user.
Item | Old Rules | Reverse Charge |
Invoice value (labour + materials) | £8,000 | £8,000 |
VAT charged on invoice (20%) | £1,600 | £0 (note added instead) |
Total Dave receives | £9,600 | £8,000 |
Who pays VAT to HMRC | Dave | The contractor |
Under the reverse charge, Dave does not add £1,600 of VAT. His invoice notes that the reverse charge applies, and the contractor accounts for the £1,600 output VAT on their own return (reclaiming it as input VAT at the same time).
📌 Example 2: Builder Working Directly for a Homeowner (Normal Rules Apply)
Sarah runs a VAT-registered building firm. She builds a £20,000 extension directly for a homeowner.
The homeowner is the end user.
The reverse charge does not apply.
Sarah charges VAT in the normal way: £20,000 + £4,000 VAT = £24,000.
As these examples show, the same trade and the same value of work can be treated completely differently - it all depends on who the customer is and where you sit in the supply chain.
📝 What Your Invoices Need to Show
If the reverse charge applies, your invoice must:
Clearly state that the “VAT domestic reverse charge applies” (or similar wording)
Show the VAT rate or the amount of VAT due - but make clear it is not being charged to the customer
Include all your usual invoice details
Your accounting software (such as Xero, QuickBooks or Sage) will usually have a dedicated reverse charge VAT code to handle this correctly.
💷 The Cash Flow Impact for Subcontractors
Here’s something many subcontractors overlook.
Before the reverse charge, you collected VAT from your customers and held onto it until your VAT Return was due - giving your business a short-term cash flow boost. Under the reverse charge, that money never reaches your account.
This means some subcontractors now regularly find themselves in a VAT repayment position (reclaiming more VAT than they owe). If that’s you, it may be worth:
Switching to monthly VAT Returns to receive repayments faster
Reviewing whether the VAT Flat Rate Scheme still works for you, as reverse charge supplies are excluded from it
⚠️ Common Mistakes We See
The reverse charge is easy to get wrong. The most frequent issues include:
Charging VAT when you shouldn’t - applying normal rules to a reverse charge supply
Not applying the reverse charge because end user status was assumed rather than confirmed
Missing or incorrect invoice wording
Forgetting materials are included when supplied alongside labour
Staying on the Flat Rate Scheme when it’s no longer beneficial
👉 These mistakes can lead to incorrect VAT Returns, repayment delays, and HMRC enquiries - all of which are avoidable with the right setup.
✅ Key Takeaways
The reverse charge changes who accounts for VAT, not how much is due.
It applies to CIS-registered, VAT-registered businesses supplying standard or reduced-rated construction services.
It does not apply where the customer is an end user (e.g. a homeowner or a business using the work itself).
Subcontractors don’t charge VAT - the contractor accounts for it instead.
