VAT Flat Rate Scheme for UK Trade Businesses — How It Works and Whether It's Right for You in 2026
Once your trade business crosses the VAT registration threshold, you face a choice that most accountants bring up almost immediately: do you use standard VAT accounting, or join the VAT Flat Rate Scheme (FRS)? For some tradespeople, the FRS puts real money back into the business each quarter. For others, it costs more than it saves. The difference often comes down to how much of your turnover is spent on materials — and whether you pass HMRC's Limited Cost Trader test.
This guide explains exactly how the scheme works, lists the 2026 flat rates for the most common UK trades, walks through a detailed comparison using a plumber on a £60,000 turnover, and covers everything you need to know about the Limited Cost Trader rules before you apply.
What is the VAT Flat Rate Scheme?
Under standard VAT accounting, you track two figures every quarter: the VAT you collected from clients (output VAT) and the VAT you paid on business purchases (input VAT). You subtract one from the other and pay HMRC the difference. In theory, simple. In practice, it means keeping receipts for every VATable purchase, reconciling them each quarter, and making sure you haven't missed anything.
The Flat Rate Scheme replaces that process with a single calculation. Instead of tracking individual purchase VAT, you pay HMRC a fixed percentage of your gross (VAT-inclusive) turnover each quarter. You still charge your clients the standard 20% VAT rate on your invoices — nothing changes on their end. But rather than deducting input VAT receipt by receipt, you simply multiply your total gross receipts by your trade's flat rate and pay that amount to HMRC.
The key insight is that every flat rate is set below 20% — which means there is almost always a gap between the VAT you collected and what you hand over to HMRC. That gap stays in your business as a benefit of the scheme. In exchange, you give up the right to reclaim input VAT on most purchases (capital asset purchases over £2,000 are an exception, covered later).
Who is eligible?
The FRS is open to VAT-registered businesses whose annual taxable turnover (excluding VAT) is £150,000 or less. Taxable turnover means the value of all supplies made at standard rate, reduced rate, or zero rate — it does not include exempt supplies or VAT itself.
Once you are on the scheme, you can stay on it until your gross (VAT-inclusive) turnover exceeds £230,000 in the previous 12 months, at which point HMRC expects you to leave. There is a band between £150,000 and £230,000 that allows businesses to stay on FRS if they joined when they were below the lower threshold.
Important: you must still charge 20% VAT to clients
The FRS changes only what you pay to HMRC — not what you charge. Your invoices must still show VAT at 20% and your clients still pay the full VAT-inclusive price. The scheme is purely about how you account for that VAT internally.
How the FRS calculation works: a step-by-step example
Here is the core mechanic, using an electrician with a flat rate of 10%:
- You issue an invoice for £1,000 + VAT
- The client pays you £1,200 (including £200 VAT at 20%)
- Your flat rate is 10%, applied to the gross amount: £1,200 × 10% = £120
- You pay HMRC £120
- You collected £200 in VAT. You pay over £120. You keep the £80 difference
That £80 is not a windfall — HMRC designed the rate assuming you spend some of your turnover on VATable goods, and the flat rate builds in an allowance for that input VAT. The benefit arises when your actual input VAT is less than the allowance assumed in the flat rate. The more labour-heavy your work, the more likely you are to benefit.
Now scale this up. On £100,000 net turnover (£120,000 gross) with a 10% flat rate: you pay HMRC £12,000, having collected £20,000 in VAT. The scheme retains £8,000 in your business. Whether that outperforms standard VAT depends on what you could have reclaimed in input VAT — the comparison is done in detail below.
2026 flat rates by trade
HMRC assigns flat rates by sector. The rates below reflect the categories relevant to UK trade businesses in 2026. Always verify your category directly on GOV.UK, as HMRC updates the list periodically.
| Trade | Flat rate | First-year rate |
|---|---|---|
| Plumber | 9.5% | 8.5% |
| Electrician | 10% | 9% |
| Builder / general building contractor | 9.5% | 8.5% |
| Roofing contractor | 14.5% | 13.5% |
| Glazier / window fitter | 12% | 11% |
| Heating engineer | 9.5% | 8.5% |
| Painter / decorator | 12% | 11% |
| Carpenter / joiner | 10% | 9% |
| Landscape gardener | 11% | 10% |
Notice that roofers sit at 14.5% — significantly higher than plumbers or builders. This reflects the fact that roofing work typically involves substantial materials spend (tiles, felt, battens, lead flashing), which HMRC has built into a higher assumed input VAT. A roofer with genuinely high materials costs may find standard VAT more competitive despite the admin overhead.
The first-year 1% discount
HMRC gives every business a 1% reduction off their flat rate for the first year of VAT registration. This applies from your VAT registration date and ends on its anniversary — regardless of when during that first year you actually join the FRS.
This means it almost always makes sense to join the FRS at the point of VAT registration rather than waiting, so you capture the full 12 months at the discounted rate. The saving is not trivial. A plumber on £120,000 gross turnover saves £1,200 in year one versus their standard rate (1% × £120,000). An electrician on the same turnover saves the same amount.
After the first year, your rate automatically reverts to the full flat rate — HMRC does not notify you. Diarising the date and reviewing your FRS status annually is good practice.
The Limited Cost Trader (LCT) rules: the catch that traps many tradespeople
In 2017 HMRC introduced the Limited Cost Trader rule to prevent labour-only businesses from using the FRS as a straightforward profit mechanism. The rule works like this: if your spending on goods is either:
- Less than 2% of your gross (VAT-inclusive) turnover in the VAT period, or
- Less than £250 per quarter (£1,000 per year), even if that amount is more than 2%,
then you are a Limited Cost Trader and must apply a flat rate of 16.5%— regardless of your trade category.
At 16.5%, the maths essentially never favours FRS. On a £30,000 gross quarter, you'd pay HMRC £4,950 having collected £5,000 in VAT. You retain just £50 — and that's before considering any input VAT you could have reclaimed under standard accounting.
Who gets caught by the LCT test?
The test is assessed per quarter, not annually. An electrician who works mainly on labour-only jobs (where the client supplies fittings), a decorator who uses client-supplied paint, or a carpenter who only fits client-purchased furniture could easily fall below the 2% goods threshold in any given quarter. Critically, the following do not count as goods for the test: subcontractor costs, fuel, insurance, accountancy fees, tools, capital equipment, and food & drink. Only materials directly incorporated into the work and consumables used on the job count.
The LCT test is the single biggest reason why many electricians, decorators, and labour-heavy contractors find the FRS does not work for them — especially on smaller jobs where the client supplies materials. If you are routinely close to the threshold, it is worth calculating your position each quarter before committing to an FRS return.
FRS vs standard VAT: a worked comparison for a plumber
Let's work through a concrete comparison. Our example: a sole-trader plumber with £60,000 net (ex-VAT) annual turnover and £15,000 of annual material purchases (pipes, fittings, valves, boiler parts).
Gross (VAT-inclusive) turnover: £60,000 × 1.2 = £72,000
Under FRS at 9.5%:
- VAT collected from clients: £60,000 × 20% = £12,000
- FRS payment to HMRC: £72,000 × 9.5% = £6,840
- Retained FRS benefit: £12,000 − £6,840 = £5,160
Under standard VAT:
- Output VAT collected: £12,000
- Input VAT reclaimable on £15,000 materials (assuming all VATable at 20%): £15,000 × 20% = £2,500
- Input VAT on other costs (van fuel, tools, accountant — estimated £4,000 ex-VAT): £4,000 × 20% = £800
- Total input VAT: £2,500 + £800 = £3,300
- Net payment to HMRC: £12,000 − £3,300 = £8,700
Comparing the two: on FRS this plumber pays £6,840 to HMRC. On standard VAT, they pay £8,700. FRS saves £1,860 per year in this scenario.
Now look at what happens if the materials spend increases. If this plumber takes on more boiler-supply-and-fit work and their materials rise to £30,000:
- FRS payment: £72,000 × 9.5% = £6,840 (unchanged — FRS does not vary with purchases)
- Input VAT under standard VAT: £30,000 × 20% + £800 (other costs) = £6,800
- Net standard VAT payment: £12,000 − £6,800 = £5,200
Now standard VAT costs £5,200 vs FRS at £6,840. Standard VAT saves £1,640 per year. The crossover for this plumber happens when recoverable input VAT exceeds £5,160 — roughly £25,800 of VATable purchases. Below that: FRS wins. Above it: standard VAT wins.
Also check the LCT position: on £72,000 gross turnover, 2% = £1,440 of goods spend per year. Our plumber spends £15,000 on materials — well above the threshold — so they are not a Limited Cost Trader and can use the 9.5% rate. A sole trader on £72,000 gross spending less than £1,440 on goods annually would be forced onto 16.5%, making FRS pointless.
What you can still reclaim on FRS: capital assets
The general rule on FRS is that you cannot reclaim input VAT on purchases. But there is one important exception: capital assets where a single asset (or a group of assets purchased together) costs more than £2,000 including VAT.
If you buy a new van for £18,000 + VAT (£21,600 inc VAT), you can make a separate claim for the £3,600 input VAT outside your FRS return. The same applies to significant equipment purchases — a new electrical testing kit costing £2,400 inc VAT, for example, or a trailer worth £3,000 inc VAT.
This exception makes the FRS more viable for trades that make occasional large capital purchases. You still benefit from the flat rate on your operating turnover, and you still recover VAT on major assets. The items that cannot be reclaimed under FRS are routine goods and services: materials, consumables, fuel, insurance, accountancy, and small tools under £2,000.
Making Tax Digital (MTD) and the FRS
Being on the Flat Rate Scheme does not exempt you from Making Tax Digital obligations. If you are VAT-registered, you must:
- Keep digital records of all your sales, the VAT charged, and the flat rate calculations
- Submit your VAT returns using MTD-compatible software (such as Xero, QuickBooks, or FreeAgent)
- Maintain a digital audit trail that connects your records to your return figures
The FRS simplifies your VAT calculation, but it does not simplify your record-keeping requirements. You still need to record each sale individually (the gross amount and the flat rate applied) and keep those records for six years. Most MTD-compatible accounting packages handle FRS returns natively — you enter your gross receipts and the software calculates the payment.
How to join the Flat Rate Scheme
You can apply for FRS online through your HMRC business tax account. The application is straightforward: HMRC asks for your business type, your expected annual taxable turnover, and your VAT registration number.
HMRC will confirm your flat rate percentage and the date from which the scheme applies. The scheme typically takes effect from the start of the next VAT return period after your application is accepted, although HMRC can sometimes backdate it to your VAT registration date if you apply within your first VAT period.
There is no fee to join. If you later decide to leave — because your turnover has exceeded the threshold, or because standard VAT has become more efficient — you write to HMRC or notify them via your online account.
When to review your FRS position
The FRS is not a set-and-forget decision. Review it annually, or whenever your business changes materially — for example, if you take on a large supply-and-fit contract, start buying significantly more materials, or move into more labour-only work. The calculation shifts with your cost base, and staying on the wrong scheme can cost hundreds or thousands of pounds per year.
Where Trade2Base fits in
One area that catches tradespeople out on the Limited Cost Trader test is marketing spend. Google Ads, Checkatrade membership, lead-generation platforms, and Facebook advertising are all services — not goods — so they do not count toward your 2% goods threshold. But knowing exactly what you spend on marketing, and what jobs that spend actually generated, matters for a different reason.
If you are weighing up whether you're close to the LCT threshold, you need accurate figures for all your costs: which are goods, which are services, and which are capital assets. Trade2Base tracks every marketing cost against the jobs it generated, so you have a clear picture of your marketing spend by channel and by job. That clarity — knowing your actual cost per booked job from each source — also feeds directly into whether your overall cost base pushes you toward standard VAT or keeps you comfortably on FRS.
