VAT on labour costs – A complete guide for UK tradespeople
For experts in trades such as construction, plumbing, and electrical installation, creating a precise quote entails more than just adding up labour costs and material costs. VAT, compliance expenses, and overheads influence the final figure. Among these, labour VAT is frequently misinterpreted. This guide explains how VAT on labour works in the UK, when it applies, where exemptions exist, and the impact on pricing and profitability.

 What VAT on labour means for tradespeople
For example, if a plumber supplies and fits a new boiler, the materials (the boiler itself) and the labour (the fitting work) must be separated when considering VAT. Failing to split the two can lead to overcharging or undercharging, both of which risk penalties during an HMRC audit.
VAT treatment depends on the main supply
In most cases, labour follows the VAT treatment of the main supply. If the primary service is standard-rated at 20 percent, then the labour charged alongside it will also be subject to 20 percent VAT. However, there are situations where reduced rates or exemptions apply:
- Standard rate (20 percent) for most construction, repair, and maintenance jobs.
- Reduced rate (5 percent) for some residential conversions and energy-saving installations.
- Zero-rated for qualifying new-build housing projects.
- Exempt or outside the scope in rare, specific cases such as MOT testing.
For tradespeople, the key is to check the nature of the main supply before deciding how to apply VAT on labour. You can also read more about choosing the right VAT scheme for your business.
When labour is not subject to VAT
- Labour on new-build residential properties, where both materials and services are zero-rated.
- Electrical work, carpentry, or decorating in new homes, where no VAT is charged, provided the job meets zero-rating criteria.
- Specific renewable energy installations, such as solar panels or qualifying insulation work.
- Some conversion projects qualify for the reduced 5 percent VAT rate.
Labour costs outside VAT scope
VAT and subcontractor costs
The domestic reverse charge for construction
- No VAT is added by the subcontractor on qualifying invoices.
- The contractor records both output VAT (sales) and input VAT (purchases) in their VAT return.
- The scheme only applies to standard or reduced-rate services, not zero-rated work.
Do all tradespeople need to charge VAT?
Not all tradespeople must charge VAT. Only businesses registered for VAT are required to include it in their invoices. Registration becomes compulsory once annual turnover exceeds £90,000 in a rolling 12-month period.
Preparing for VAT registration
Practical impact of VAT on labour
Charging VAT correctly affects more than compliance. It has a direct influence on pricing and profitability. For example:
- A self-employed electrician who is VAT-registered must add 20 percent to their labour charges. If their clients are domestic households, this can make their quotes seem higher than those of non-registered competitors.
- A building contractor working for a VAT-registered developer, however, can add VAT without issue, since the client can reclaim it. In this case, being VAT-registered is beneficial because input VAT on tools, machinery, and subcontractor bills can be reclaimed.
Tradespeople should therefore consider who their primary clients are before deciding whether voluntary registration is a good fit.
Best practices for managing labour VAT
- Separate labour and materials on all invoices.
- Verify whether the job qualifies for reduced or zero-rated rates before quoting.
- Keep detailed digital records to support VAT returns.
- Communicate VAT rules to subcontractors to avoid incorrect charges.
- Use VAT-compliant software to simplify calculations and submissions.
Common mistakes to avoid
- Mixing labour and material charges in one line without clarifying VAT.
- Charging VAT on exempt or zero-rated projects.
- Using the wrong percentage under the Flat rate Scheme.
- Failing to register once turnover exceeds £90,000.
Avoiding these mistakes helps businesses remain compliant, avoid HMRC penalties, and support long-term profitability.
Conclusion
- VAT on labour is more than an accounting detail. For UK tradespeople, it shapes how quotes are prepared, how invoices are issued, and how profits are managed. By understanding when labour attracts VAT, when it qualifies for reduced or zero rates, and how schemes like the reverse charge apply, tradespeople can protect margins and maintain compliance.
- Careful record-keeping and the right software tools also make reporting easier. In the end, handling VAT on labour correctly is not only about staying on the right side of HMRC, but also about showing clients that you run a reliable and professional business.
Frequently Asked Questions:
Your Questions – Answered ,We’re here to help you with anything VAT-related.
  1. What counts as labour for VAT purposes? 
 
			
			
		 
 Labour for VAT purposes refers specifically to the work performed by a tradesperson, including activities like installation, fitting, repair, or maintenance. It does not include materials, products, or equipment supplied, unless they are an inseparable part of a composite service.
For instance, when installing a kitchen, the fitting of cabinets, sinks, and appliances constitutes labour, whereas the cabinets and appliances themselves are treated separately for VAT.
Correctly identifying which portion of the job is labour ensures that VAT is applied accurately and consistently. It also helps tradespeople produce transparent and compliant invoices, reducing the risk of errors during HMRC inspections or audits.
  2. Do all tradespeople need to charge VAT on labour? 
 
			
			
		 
   3. How does the Flat Rate Scheme affect labour VAT? 
 
			
			
		 
 The Flat Rate Scheme (FRS) is designed to simplify VAT accounting for small businesses. Under the scheme, tradespeople pay a fixed percentage of their turnover rather than calculating VAT on each invoice line separately. This means labour costs are included in the total turnover, and the percentage applied may result in an effective VAT rate lower than the standard 20 percent.
While FRS reduces administrative work, accurate record-keeping remains crucial because the fixed rate must be applied consistently across all invoices, including those with mixed materials and labour charges. Selecting the correct flat-rate category for your trade is crucial to avoid underpaying or overpaying VAT.
Tradespeople benefit from using FRS if their input VAT is low relative to turnover. Still, they should assess profitability carefully, as some jobs with higher material costs may reduce the scheme’s advantage. Using software can further streamline compliance and reporting.
  4. Can labour VAT be zero-rated or exempt? 
 
			
			
		 
 Yes, in some instances, labour can be zero-rated or exempt from VAT. For example, specific construction services on qualifying new-build residential properties are exempt from VAT. Some maintenance and repair services, particularly on residential buildings, may also fall under reduced or exempt categories. Tradespeople need to verify the VAT status of each job before applying charges.
Misclassifying labour can lead to HMRC penalties, interest on unpaid Tax, or disputes with clients. Using guidance from HMRC, digital accounting tools, or VAT software can help determine whether a service is standard-rated, reduced, zero-rated, or exempt.
  5. Why is separating labour and material costs important for VAT? 
 
			
			
		 
 Separating labour and material costs on invoices is essential for accurate VAT accounting. Labour and materials often attract different VAT treatments: labour may be standard-rated, reduced, or exempt, while materials may have a separate rate. Combining them can result in incorrect VAT charges, which may trigger HMRC scrutiny and potential penalties.
Clear separation improves transparency for clients, making it clear what they are paying for and how VAT is applied. It also allows tradespeople to analyse costs accurately, determine the profitability of individual services, and price jobs competitively. Good record-keeping supports financial control, simplifies VAT returns, and prevents errors during audits.
Using accounting or invoicing software can make separating costs easier, reduce mistakes, and maintain consistent practices across all projects, helping businesses operate efficiently and maintain credibility with both clients and HMRC.
