The VAT Flat Rate Scheme for trades can simplify VAT reporting for UK plumbers, electricians, builders, and contractors — but it is not always the most profitable option.
In this guide, we explain how the flat rate scheme works, the percentages applied to different trades, who qualifies, and whether it still makes sense in 2026.
What Is the VAT Flat Rate Scheme?
The VAT Flat Rate Scheme (FRS) allows small VAT-registered businesses to pay a fixed percentage of their gross turnover to HMRC instead of calculating VAT on every individual purchase and sale.
Under the scheme:
- You still charge customers 20% VAT.
- You pay HMRC a lower fixed percentage of your total VAT-inclusive turnover.
- You cannot usually reclaim VAT on most purchases.
The scheme was designed to simplify VAT reporting for small businesses.
Official guidance is available from HMRC
Who Can Use the VAT Flat Rate Scheme?
To qualify in 2026:
- Your VAT taxable turnover must be £150,000 or less (excluding VAT).
- You must not have left the scheme in the last 12 months.
- You must not be part of a VAT group.
Many sole traders and small trade businesses fall within this threshold.
VAT Flat Rate Percentages for Trades (2026)
Different trades have different flat rate percentages.
Examples (check HMRC for updates):
- General building or construction services – typically around 9.5%
- Plumbing – around 10%
- Electrical work – around 14.5%
- Decorating – around 14.5%
If your business is considered a “limited cost trader,” a higher rate (currently 16.5%) may apply.
This is where many tradespeople get caught out.
What Is a Limited Cost Trader?
A limited cost trader is a business that spends very little on goods compared to turnover.
If your goods are less than:
- 2% of turnover
or - £1,000 per year (whichever is greater)
You may be classified as a limited cost trader.
In that case, your flat rate becomes 16.5%, which often removes the benefit of the scheme.
Service-heavy trades with low material costs are most at risk of falling into this category.
Example: VAT Flat Rate for a Plumber
Let’s say a VAT-registered plumber invoices £60,000 + VAT annually.
Total VAT-inclusive turnover:
£72,000
If their flat rate percentage is 10%:
£72,000 × 10% = £7,200 payable to HMRC
Under normal VAT accounting, they would:
- Charge £12,000 VAT
- Reclaim VAT on purchases
- Pay the difference
Depending on material costs, the flat rate scheme may result in paying less — or sometimes more.
This is why it’s important to calculate both options before choosing.
Advantages of the VAT Flat Rate Scheme for Trades
- Simpler bookkeeping
- Predictable VAT payments
- Less administrative time
- Potential small profit margin benefit
- Easier cash flow planning
For sole traders and small building firms, simplicity can be valuable.
Disadvantages
– Cannot usually reclaim VAT on materials
– Limited cost trader rules reduce benefit
– Not ideal for material-heavy construction firms
– May become less beneficial as business grows
For builders purchasing large volumes of materials, standard VAT accounting may be more advantageous.
How to Calculate Whether the Flat Rate Scheme Saves You Money
Before choosing the VAT Flat Rate Scheme for trades, you should compare both methods.
Step 1 – Calculate your annual VAT-inclusive turnover.
Step 2 – Apply your flat rate percentage.
Step 3 – Compare that number to what you would pay under standard VAT accounting.
Under standard VAT:
- Add VAT charged to customers.
- Subtract VAT reclaimable on materials and eligible purchases.
- Pay the difference to HMRC.
If your material costs are high, standard VAT is often more beneficial.
If your business is labour-heavy, flat rate may create a small margin benefit.
Even a 1–2% difference in effective VAT can amount to thousands per year.
Is the VAT Flat Rate Scheme Worth It for Trades in 2026?
It depends on:
- Your material costs
- Your turnover
- Whether you fall under limited cost trader rules
- Your administrative capacity
For:
Sole traders with modest material expenses → Often worthwhile.
Material-heavy contractors → Often not beneficial.
Growing businesses → Usually transition off the scheme.
VAT Flat Rate vs Standard VAT Accounting
Flat Rate Scheme:
- Simple calculation
- Fixed percentage
- Minimal VAT reclaim
Standard VAT:
- More complex
- Reclaim VAT on materials
- More detailed bookkeeping
Accounting software designed for trades can calculate both methods to compare which is more beneficial.

VAT Flat Rate Scheme for Builders
Builders purchasing large quantities of materials often reclaim significant VAT under standard accounting.
Because the flat rate scheme prevents most VAT reclaims, many construction firms find standard VAT more beneficial.
However, small builders with lower material-to-labour ratios may still benefit.
VAT Flat Rate for Plumbers
Plumbers typically fall into mid-range flat rate percentages.
If material purchases are moderate and overheads are predictable, the scheme can simplify reporting.
However, large project work with substantial materials may reduce the benefit.
VAT Flat Rate for Electricians
Electricians often operate with a mix of labour and materials.
If material spend is consistent and substantial, comparing both schemes carefully is important before deciding.
When Should Trades Leave the Flat Rate Scheme?
Trades businesses should review their position if:
- Turnover approaches £230,000 (exit threshold)
- Material costs increase significantly
- Limited cost trader classification applies
- Business structure changes (e.g., incorporation)
Flat rate is often a starting solution — not a long-term strategy for scaling firms.
Why Accounting Software Matters for VAT Compliance
Whether using flat rate or standard VAT, digital record keeping is mandatory under Making Tax Digital.
Modern accounting software for trades allows you to:
- Track VAT automatically
- Compare flat rate vs standard VAT
- Submit VAT returns directly to HMRC
- Monitor cash flow impact in real time
This reduces error risk and improves visibility.
Common Questions
Can electricians use the VAT Flat Rate Scheme?
Yes, if they meet turnover limits and do not fall under limited cost trader rules.
Do builders benefit from the flat rate scheme?
Sometimes, but high material costs often make standard VAT more beneficial.
Can you leave the flat rate scheme?
Yes. You can voluntarily leave or be required to leave if turnover exceeds limits.
Does the scheme affect CIS?
No. CIS and VAT operate separately.
Final Thoughts
The VAT Flat Rate Scheme for trades can reduce admin and provide small cash flow advantages — but it is not automatically the best choice for every plumber, electrician, or builder.
Before choosing:
- Calculate both methods.
- Consider material costs.
- Review limited cost trader rules.
- Use accounting software that models VAT accurately.
Making the wrong choice can quietly cost thousands over time.
