VAT for Construction: A Guide to Rates and Reverse Charge

Getting VAT right on construction invoices is critical. Apply the wrong rate and you face HMRC penalties, delayed payments, or cash flow problems. This guide covers every VAT rate that applies to UK construction work, including the Domestic Reverse Charge (DRC) that catches many subcontractors off guard.

VAT Rates That Apply to Construction

There are six VAT treatments you may encounter on construction projects in the UK:

Standard Rate: 20%

The default VAT rate for most construction services. If you are a VAT-registered subcontractor providing building, repair, or maintenance services, you will typically charge 20% VAT on your invoices. This applies to:

• New commercial buildings
• Extensions and alterations to existing buildings
• Repair and maintenance work
• Most fit-out and refurbishment projects

Reduced Rate: 5%

The 5% reduced rate applies in specific circumstances:

• Converting a non-residential building into residential dwellings
• Renovating a dwelling that has been empty for 2+ years
• Installing energy-saving materials (insulation, solar panels, heat pumps) in certain qualifying properties
• Converting a house into flats (or vice versa)

The reduced rate must be properly documented. If HMRC challenges your use of 5%, you may need to provide evidence that the building qualifies.

Zero Rate: 0%

Zero-rated construction means you charge 0% VAT but can still reclaim input VAT on your costs. It applies to:

• Construction of new residential dwellings (houses, flats)
• Construction of buildings for qualifying charitable use
• Approved alterations to listed buildings (though this has been restricted since 2012)

Important: Zero-rating only applies to new builds, not to extensions, alterations, or refurbishments of existing residential properties.

Exempt

Some property transactions are exempt from VAT entirely. This mainly affects the sale or long lease of existing commercial buildings (unless the owner has opted to tax). As a subcontractor, you will rarely encounter exempt supplies in your day-to-day invoicing.

The Domestic Reverse Charge (DRC)

The Domestic Reverse Charge for building and construction services came into effect on 1 March 2021. It fundamentally changes how VAT works between businesses in the construction supply chain.

What Is the Reverse Charge?

Under the DRC, the customer accounts for the VAT, not the supplier. As a subcontractor, you issue an invoice showing the VAT amount but you do not collect it. Instead, your customer (the main contractor) accounts for both the output and input VAT on their own VAT return.

When Does the DRC Apply?

The reverse charge applies when all of these conditions are met:

1. The supply is of specified construction services (most building work qualifies)
2. Both parties are VAT-registered
3. Both parties are registered for CIS (Construction Industry Scheme)
4. The customer is not an end user or intermediary connected to the end user

DRC 20% vs DRC 5%

The reverse charge applies at the same rate that would normally apply to the supply:

• DRC 20% applies to standard-rated construction services under the reverse charge
• DRC 5% applies to reduced-rated work (e.g. renovations of empty dwellings) under the reverse charge

How to Invoice Under the DRC

Your invoice must:

• State that the domestic reverse charge applies
• Show the VAT rate and amount (but not collect it)
• Include the customer's VAT number
• Note that the customer must account for the VAT

Which VAT Rate Should You Set as Your Default?

When setting a company-wide default VAT rate in your project management software, consider:

• Standard 20% if most of your work is commercial or residential repair/maintenance
• DRC 20% if you primarily subcontract to VAT and CIS-registered main contractors
• Zero if you mainly build new residential properties
• You can always override the default on each individual project

Common VAT Mistakes in Construction

1. Charging VAT when the DRC applies: if you collect VAT that should have been reverse-charged, both you and your customer face penalties
2. Using the wrong rate on mixed projects: a project with both new-build and refurbishment elements may require split rates
3. Not displaying the DRC notice on invoices: HMRC requires a clear statement that the reverse charge applies
4. Applying zero rate to extensions: zero-rating only covers new builds, not extensions to existing dwellings

Frequently Asked Questions

Do I still need to be VAT-registered to use the reverse charge?

Yes. Both the supplier and customer must be VAT-registered. If you are below the VAT threshold and not registered, the DRC does not apply to you.

Does the DRC affect my cash flow?

Yes, significantly. Under normal VAT rules, you collect VAT from your customer and later pay it to HMRC. Under the DRC, you do not collect the VAT, so your invoices are lower by 20%. This can create a cash flow advantage if you were previously paying VAT to HMRC before your customer paid you, but it means less cash coming in on each invoice.

What if I am the last contractor in the chain (end user)?

If you are the end user of the construction services (e.g. a property developer building for your own portfolio), the reverse charge does not apply. Your subcontractor should charge you VAT normally.

Where can I find more guidance?

HMRC publishes detailed guidance on the VAT domestic reverse charge for construction on GOV.UK.
