VAT for Tradespeople UK: When to Use 20%, 5% or 0% on Invoices

VAT for Tradespeople UK: When to Use 20%, 5% or 0% on Invoices

You finish a job.

You create the invoice.

Then you reach the VAT box.

20%?

5%?

0%?

For many tradespeople, that is where something that should take a few seconds becomes surprisingly complicated.

And the problem is not imaginary.

UK discussions about trade pricing repeatedly show confusion from both sides. Customers complain about discovering VAT after receiving a trade quote, while small-business owners describe getting to grips with VAT in the building trade as confusing.

The reason is simple:

Not every job necessarily carries the same VAT treatment.

HMRC says the VAT rate can depend on factors including exactly what is being supplied, who is buying it, where it is supplied, whether particular conditions are met and whether supporting evidence is required.

For a tradesperson, that can mean one job is standard-rated at 20%, another qualifying job may be reduced-rated at 5%, while certain work can qualify for 0% VAT.

That means your invoicing system needs to do more than have one VAT switch for the entire business.

You need to be able to apply the appropriate VAT treatment to the actual item you are quoting or invoicing.

That is the problem Love Invoicing is designed to make easier.

Why VAT Is Particularly Confusing for Builders and Tradespeople

For many businesses, almost everything they sell uses the standard VAT rate.

Construction and property work can be more complicated.

HMRC states that work carried out to an existing building will normally be standard-rated, but specific reliefs can apply in particular circumstances. For example, some qualifying residential conversions and renovation work on eligible dwellings that have been unoccupied for at least two years can qualify for the reduced 5% rate.

Certain qualifying construction of new domestic buildings can be zero-rated.

And there is currently another important rule affecting some energy-saving work.

Qualifying installations of specified energy-saving materials in residential accommodation currently benefit from a temporary 0% rate, with HMRC stating that the relief runs until 31 March 2027 before reverting to 5% from 1 April 2027.

So a blanket:

“I'm VAT registered, therefore every job is 20%”

is not a safe way to think about VAT.

Likewise:

“It's building work, therefore it's 5%”

is also wrong.

The treatment depends on the actual supply and whether the relevant HMRC conditions are satisfied.

The Five VAT Treatments You May Need to Distinguish

Love Invoicing provides separate VAT treatment choices because 0%, exempt and outside the scope of VAT are not the same thing.

That distinction matters.

1. Standard rate — 20%

The standard UK VAT rate is 20% and will apply to many ordinary taxable goods and services.

For tradespeople, ordinary repair, maintenance and improvement work to an existing property will normally fall into the standard-rated category unless a specific relief applies.

For example, an ordinary domestic repair that does not qualify for a reduced or zero rate would normally be considered under the standard-rate rules.

2. Reduced rate — 5%

The reduced 5% VAT rate only applies where the relevant conditions are met.

One important construction example is certain qualifying residential renovation or alteration work, including eligible dwellings that have not been lived in during the two years immediately before the work begins.

HMRC's VAT rate guidance also identifies qualifying residential conversions as an area where the 5% rate can apply.

The important word is qualifying.

Do not choose 5% simply because the work involves a house.

3. Zero-rated — 0%

Zero-rated supplies are still taxable supplies — but the VAT rate applied is 0%.

HMRC specifically distinguishes zero-rated supplies from exempt supplies. Zero-rated supplies remain taxable for VAT purposes even though no VAT is added to the selling price.

This distinction matters for tradespeople because some construction and energy-saving work can qualify for zero rating.

4. Exempt

Exempt is not another name for 0% VAT.

HMRC is explicit about this.

Both can result in no VAT being added to the selling price, but an exempt supply is not taxable in the same way as a zero-rated supply, and the treatment of VAT incurred on related business costs can differ.

That is why Love Invoicing keeps Zero-rated and Exempt as separate tax-treatment choices.

5. No VAT / Out of scope

Some transactions sit outside the UK VAT system altogether.

HMRC gives examples including certain statutory fees, genuine donations and supplies whose place of supply is outside the UK.

Again:

Out of scope ≠ exempt ≠ zero-rated.

They may all result in no VAT being added, but they are different VAT treatments.

The Real Problem: Your VAT Rate Can Depend on the Line Item

This is where invoicing software needs to be designed properly.

Imagine a quote containing several different items.

The VAT treatment should follow the actual supply.

HMRC's VAT invoicing guidance requires VAT information to be sufficiently clear, and its detailed invoice rules include the VAT rate and amount payable excluding VAT for relevant invoice items.

That makes line-item VAT important.

Instead of setting one permanent rate and hoping every job fits it, Love Invoicing lets the user set the tax treatment against the relevant item.

Save the VAT Treatment in Your Price List

Suppose you regularly provide:

• Boiler fitting
• Hob fitting
• Copper pipe replacement
• Flooring installation
• Electrical work

Rather than entering the service, price and VAT treatment repeatedly every time you prepare a quote or invoice, you can save commonly used services in the Love Invoicing Price List.

Each item can contain information including:

• item type
• service or product name
• description
• unit price
• SKU where applicable
• unit
• tax treatment

Once you have set the appropriate VAT treatment against that stored item, the saved information can be reused when you select that item during quote or invoice creation.

That reduces repetitive entry and, importantly, reduces the chance of accidentally selecting a different VAT treatment each time you use the same service.

Set a VAT Treatment When You Create the Price-List Item

When a new service is created, Love Invoicing allows the user to choose its tax treatment.

For example:

Service: Boiler Fitting

Unit price: £1,250

Tax treatment: Standard 20%

Once that treatment is stored with the price-list item, selecting the service during quote or invoice creation can carry its saved VAT treatment into the line item.

You do not need to remember and re-enter the rate every time.

What if the Service Is Not in Your Price List?

This is an important workflow.

You should not have to stop creating an invoice just because the service has never been saved before.

Imagine you are invoicing for:

Solar panel installation

but that service is not currently stored in your Price List.

You can simply enter:

Solar panel installation

directly into the invoice or quote line item.

You can then enter:

• quantity
• price
• VAT treatment
• discount where applicable

without first having to create a permanent price-list record.

That is particularly useful for unusual jobs or one-off work.

Does Love Invoicing Decide the Correct Legal VAT Rate for You?

No — and this distinction is important.

Love Invoicing helps you apply and calculate the VAT treatment you select.

It does not replace HMRC guidance or decide whether a job legally qualifies for a reduced or zero rate.

That decision depends on the actual supply and the HMRC conditions applicable to it. HMRC specifically says VAT rates can depend on factors such as the precise nature of the service, the customer, where it is supplied, supporting evidence and whether it is supplied alongside other goods or services.

The workflow is therefore:

You determine the appropriate VAT treatment

↓

Select it on the Price List item or invoice/quote line

↓

Love Invoicing applies the selected percentage and calculates the totals

That is the right division of responsibility.

A Very Current Example: Solar Panel Installation

Your screenshot gives us an excellent real-world example.

Suppose you enter:

Solar panel installation

Price excluding VAT: £1,000

Which VAT rate should you choose?

You cannot answer that purely from the words “solar panel installation”.

But for a qualifying installation of specified energy-saving materials in eligible residential accommodation, HMRC currently provides a temporary 0% VAT rate. The current relief runs until 31 March 2027, with qualifying installations scheduled to revert to the reduced 5% rate from 1 April 2027.

So where that £1,000 solar installation genuinely satisfies the current zero-rating conditions, selecting:

0% — Zero rated

results in:

Price ex VAT: £1,000

VAT: £0

Total including VAT: £1,000

The software handles the calculation after you select the correct treatment.

But Do Not Assume Every Solar Job Is 0%

This is precisely the kind of mistake the article needs to prevent.

HMRC's relief applies to qualifying installations and is subject to conditions. The tax treatment can depend on the nature of the installation, the property and the circumstances of the supply.

So the lesson is not:

“Solar panels = always 0%.”

The lesson is:

Check whether the supply qualifies, then select the correct treatment against that line item.

That is exactly why the VAT rate must remain editable.

Example: Ordinary Repair Work

Now compare that with a straightforward repair to an existing home.

HMRC says work to an existing building will normally be standard-rated unless a specific relief applies.

Suppose the job is:

Ordinary plumbing repair

Price ex VAT: £200

and no reduced or zero-rate provision applies.

Selecting:

Standard — 20%

would give:

£200 + £40 VAT = £240

Love Invoicing performs the calculation based on the selected VAT treatment.

Example: Qualifying 5% Residential Work

There are also situations where 5% VAT can legitimately apply.

For example, HMRC allows reduced rating for certain qualifying residential conversions and some renovation work on dwellings that meet the relevant empty-property conditions.

Suppose a qualifying job has:

Net value: £1,000

At 5%:

VAT: £50

Total: £1,050

Again, the important part is establishing first that the work actually meets HMRC's conditions.

The software then takes care of applying the percentage.

Why the VAT Selector Belongs Inside the Invoice and Quote

A Price List is useful for repeat work.

But tradespeople do not only perform repeat work.

You will inevitably create:

• one-off jobs
• unusual repairs
• bespoke installations
• custom materials
• project-specific services

Forcing every one of those into a permanent catalogue before you can issue a quote would slow the job down.

That is why Love Invoicing also puts the VAT selector inside the quote and invoice line-item workflow.

Type the service.

Enter the price.

Choose the VAT treatment.

Continue.

Why This Matters on Quotes as Well as Invoices

VAT confusion should not first appear after the work is complete.

One public UK discussion specifically complains about trade quotes where the customer does not feel the final VAT-inclusive cost was clear from the outset.

That is a bad customer experience even before you get into the accounting consequences.

A better workflow is to establish the correct tax treatment while preparing the quote.

Then the customer sees a clearer price before accepting the work.

When that work later becomes an invoice, you are not suddenly trying to reconstruct the VAT decision from memory.

HMRC also requires VAT information to be properly represented on applicable VAT invoices.

Don't Confuse Zero-Rated With Exempt

This is worth repeating because it causes genuine accounting problems.

Consider two transactions where the invoice adds £0 VAT.

They may look identical from the customer's point of view.

But they are not necessarily identical for VAT purposes.

HMRC states that:

Zero-rated supplies remain taxable supplies at 0%.

By contrast:

Exempt supplies are not taxable supplies in the same way and can affect the recovery of VAT on associated costs.

This is why your system should preserve the tax treatment, not merely the numerical VAT amount.

And Don't Confuse Exempt With Out of Scope

Out-of-scope transactions sit outside the UK VAT system.

HMRC gives examples such as certain statutory fees and genuine donations where nothing is supplied in return.

So this:

0%

this:

Exempt

and this:

No VAT / Out of scope

should not simply be collapsed into:

No tax

because they describe different things.

Love Invoicing keeps them as separate options so the user can preserve the intended treatment.

What Should a Tradesperson Do Before Selecting a VAT Rate?

For anything straightforward, you may already know the normal VAT treatment your business uses.

For unusual work, ask:

What exactly am I supplying?

Labour?

Materials?

An installation?

A conversion?

A qualifying energy-saving measure?

What kind of property is involved?

Existing domestic property?

Commercial building?

New dwelling?

A qualifying conversion?

Does a reduced or zero-rate provision actually apply?

Do not apply 5% or 0% simply because it makes the quote cheaper.

Do I have the evidence required?

HMRC states that eligibility for particular VAT rates can depend on appropriate evidence and records.

If you are uncertain, check HMRC guidance or confirm the treatment with your accountant before issuing the VAT invoice.

One Price List Can Contain Different VAT Treatments

This is another practical advantage.

Your business does not have to be:

“a 20% VAT business”

or:

“a 5% VAT business.”

Individual taxable supplies can have different treatments where the law provides for them.

So a Price List could contain services where one stored item normally uses:

20%

while another qualifying service is stored with:

0%

or another permitted treatment.

When the stored item is selected, its saved tax treatment can come with it.

And if the job circumstances require a different legally appropriate treatment, the line-item workflow lets the user select the applicable rate.

Stop Recalculating VAT on a Calculator

Another unnecessary workflow looks like this:

Job price: £1,250

↓

Open calculator.

↓

Multiply by 20%.

↓

Add £250.

↓

Type £1,500 into invoice.

Then repeat for the next item.

That is exactly the type of basic calculation invoicing software should remove.

The user's job is to identify the appropriate tax treatment.

The software's job is to apply that rate consistently and calculate the totals.

The Bigger Problem Is Not the Maths. It Is Choosing the Wrong Rate

Calculating:

£1,000 × 20%

is easy.

Knowing whether the transaction should actually be:

20%

5%

or:

0%

is the difficult part.

That is why the best workflow is not a giant VAT calculator.

It is:

clear tax-treatment choices + reusable Price List items + editable line-item VAT + automatic calculations.

VAT Information Should Follow the Work

The wider Love Invoicing workflow is:

Customer

↓

Quote

↓

Job

↓

Invoice

↓

Payment

VAT should not become a disconnected accounting exercise at the end.

If you establish the appropriate VAT treatment while quoting or selecting the service, that information becomes part of the commercial record surrounding the work.

That is cleaner than finishing the job and then wondering:

“What VAT did I mean to charge on this?”

Frequently Asked Questions

What is the standard VAT rate for tradespeople in the UK?

The UK standard VAT rate is 20%. Most ordinary taxable work on existing buildings is normally standard-rated unless a specific reduced or zero-rate provision applies.

When can builders charge 5% VAT?

The 5% reduced rate can apply in specific circumstances, including certain qualifying residential conversions and eligible renovation or alteration work. The conditions need to be checked against HMRC guidance.

Can building work be 0% VAT?

Yes, some qualifying construction supplies can be zero-rated. Certain qualifying installations of specified energy-saving materials also currently benefit from a temporary zero rate.

Is solar panel installation currently 0% VAT?

Qualifying installations of specified energy-saving materials, including qualifying solar installations in the circumstances covered by HMRC's relief, can currently be zero-rated. The temporary relief is scheduled to run until 31 March 2027.

Does 0% VAT mean the same thing as VAT exempt?

No. Zero-rated supplies are taxable supplies at 0%, while exempt supplies have a different VAT treatment.

Is out of scope the same as exempt?

No. Out-of-scope transactions fall outside the UK VAT system, while exempt supplies are a separate category under VAT rules.

Can I set VAT against individual items in Love Invoicing?

Yes. Love Invoicing allows a tax treatment to be associated with an item rather than forcing every line to use one permanent rate.

Can a Price List item remember its VAT treatment?

Yes. A Price List item can have its tax treatment set when the item is created, allowing the stored item and its VAT treatment to be reused during invoicing and quoting.

What if the service is not saved in my Price List?

You can enter an item directly when creating a quote or invoice and choose the VAT rate from the line-item form.

Does Love Invoicing automatically decide whether my work qualifies for 5% or 0% VAT?

No. The user must determine the legally appropriate VAT treatment. Love Invoicing then applies the selected percentage and calculates the invoice or quote totals.

Can different invoice lines use different VAT treatments?

Love Invoicing's line-item VAT workflow is designed to allow the VAT treatment to be selected against the relevant item. Whether different rates are legally appropriate depends on the actual supplies and HMRC rules.

Does HMRC require VAT information on invoices?

UK invoices must include the VAT amount where applicable, and HMRC's detailed VAT invoice guidance sets requirements around the rate and VAT-related amounts on invoice items.

The Goal Is Simple: Apply the Right VAT Without Slowing Down the Job

VAT does not need to turn every invoice into an accounting exercise.

But the software also should not pretend that every trade job is automatically 20%.

UK tradespeople can encounter:

20% standard-rated work

5% qualifying reduced-rated work

0% qualifying zero-rated work

as well as:

exempt

and:

out-of-scope

transactions.

The hard part is determining which treatment legally applies.

Once you know that, Love Invoicing gives you a straightforward way to use it:

Save the VAT treatment with a Price List item

or:

Enter a one-off line directly on the quote or invoice

↓

Choose the appropriate VAT treatment

↓

Let Love Invoicing calculate the figures

So instead of switching between your invoice, an old spreadsheet and a calculator, the VAT calculation remains part of the same workflow as the work itself.

Run the job. Send the invoice. Get paid.

Screenshot order I recommend

For this article I would use the screenshots in this order:

Why

1 VAT Rate selector - Immediately answers the article's 20% / 5% / 0% question

2 Price List - Shows reusable trade services

3 - Create Price List item - Shows tax treatment stored with the service

4 - Tax Treatment selector - Explains all five UK tax-treatment options

5 - Ad-hoc Solar Panel Installation line - Proves no Price List item is required

6 Solar item at £1,000 + 0% VAT - Shows the calculation/result

7 - VAT Rate selector inside New Invoice - Proves VAT can be selected directly while invoicing

One important product point: do not market the app as “automatically choosing the correct VAT rate.” That would be dangerous and legally inaccurate. The stronger and safer claim is:

“Save a VAT treatment against Price List items so the rate is carried into future quotes and invoices. For one-off items, choose the VAT treatment directly while creating the quote or invoice, and Love Invoicing automatically calculates the VAT.”
