When Can You Charge 5% VAT, 0% VAT or 20% VAT?
One of the most common questions bathroom retailers receive is:
“My builder says this project qualifies for 5% VAT – can you invoice me at the reduced rate?”
Another frequent enquiry comes from customers purchasing specialist bathrooms for disabled family members who have heard that VAT relief may be available.
Getting the VAT treatment wrong can be expensive. If HMRC later determines that the wrong rate was applied, it is usually the retailer who becomes liable for the VAT shortfall, together with interest and potentially penalties.
Fortunately, understanding the key rules and implementing robust procedures can help retailers protect themselves whilst still securing sales.
Scenario 1: Residential Conversions and Renovations
Many building projects qualify for a reduced VAT rate of 5%, including:
- Converting a commercial building into a dwelling.
- Converting a single dwelling into multiple dwellings.
- Converting multiple dwellings into one dwelling.
- Renovating a dwelling that has been empty for at least two years.
- Bringing certain buildings back into residential use.
However, there is a crucial distinction that is often misunderstood.
The 5% Rate Generally Applies to Builders, Not Retailers
HMRC’s reduced rate is primarily intended for qualifying construction services and for building materials supplied and installed by the contractor as part of those services.
If a bathroom retailer simply sells goods to a customer:
- Bathroom suites
- Baths
- Showers
- Taps
- Tiles
- Furniture
the supply is normally a standard-rated supply of goods and VAT must be charged at 20%
Example – 20% VAT applies
A customer purchases a £10,000 bathroom suite directly from a showroom for a former office conversion project.
The retailer is supplying goods only.
VAT must be charged at 20%.
5% VAT may apply
A VAT-registered contractor purchases and installs qualifying materials as part of a residential conversion project.
The contractor may be able to charge the customer 5% VAT on the qualifying works and incorporated materials
What About DIY Converters?
Customers often argue that they can reclaim VAT themselves.
In some circumstances this may be true.
Individuals converting non-residential buildings into dwellings may be entitled to recover VAT on qualifying materials through HMRC’s DIY Housebuilders and Converters Scheme. However, this is a claim made by the customer and does not change the retailer’s obligation to charge VAT correctly at the point of sale.
The retailer should still invoice with VAT at 20%.
Scenario 2: Bathrooms for Disabled Individuals
This is where the rules become far more interesting.
Unlike residential conversion projects, there are circumstances where a retailer may legitimately charge VAT at 0%.
HMRC provides specific VAT relief where goods and services are supplied to a person who is chronically sick or disabled.
The relief is intended to reduce the cost of products and adaptations that are necessary because of the person’s disability.
Who Qualifies?
Examples may include:
- Walk-in baths.
- Level-access shower installations.
- Adapted washrooms.
- Accessibility fixtures designed specifically for disabled users.
- Certain specialist sanitary equipment.
The exact VAT position depends on both the product and how it is supplied
What Documentation Is Needed?
A retailer should never simply accept a verbal statement that a customer is disabled.
Before zero-rating a qualifying supply they should obtain:
A Signed Eligibility Declaration
The declaration should confirm:
- The customer is chronically sick or disabled.
- The goods or services are for their personal or domestic use.
- The information provided is correct.
HMRC places responsibility on the supplier to obtain and retain appropriate evidence
A Practical Sales Opportunity
Many retailers see VAT as a reason a sale is lost.
In reality, it can become a powerful sales tool.
Instead of simply saying:
“We have to charge 20% VAT.”
consider saying:
“Let’s check whether your circumstances qualify for any VAT relief. We can guide you through the process and help you understand the options available.”
Customers appreciate retailers who help them navigate complex rules.
Five Ways to Protect the Sale
1. Train Staff to Ask the Right Questions
When customers mention:
- Property conversions
- Empty homes
- Disability adaptations
- Care needs
- Accessible bathrooms
staff should recognise that VAT relief may be relevant.
This positions the retailer as an expert rather than simply a supplier.
2. Create a VAT Relief Checklist
Provide a simple one-page form covering:
- Residential conversion projects.
- Disabled person reliefs.
- Required declarations.
- Supporting evidence.
Customers value guidance.
3. Partner with Local Installers
Where customers are carrying out qualifying conversion works, the retailer can introduce trusted installers who may be able to apply the reduced VAT rate correctly to installation services. This creates additional value and increases the chance of securing the product sale.
4. Explain VAT Recovery Opportunities
Where appropriate, explain that:
- Contractors may benefit from reduced-rate VAT on qualifying works.
- Some self-builders and converters may be able to submit claims to HMRC after completion
Customers often abandon purchases because they believe the VAT cost is permanent when it may not be.
5. Market Accessible Bathrooms Proactively
Instead of treating VAT relief as an administrative issue, use it as a marketing opportunity.
Examples include:
- “Specialist Disabled Bathroom Solutions”
- “VAT-Free Accessible Bathrooms Available for Eligible Customers”
- “We Handle the VAT Relief Paperwork”
These messages can differentiate your business from competitors.
The Bottom Line
For most bathroom retailers, a supply-only sale remains subject to VAT at 20%, even where the customer is converting a building into residential use. The 5% reduced rate is generally available to contractors providing qualifying construction services and incorporated materials, not retailers supplying goods alone.
However, genuine opportunities exist for disabled customer reliefs. By understanding the rules, obtaining the correct declarations and training staff to identify qualifying situations, retailers can remain compliant whilst turning VAT knowledge into a commercial advantage.
Retailers who understand VAT don’t just avoid risk—they use that knowledge to win business.
