What can a self-employed scaffolder claim?
A scaffolding firm is three businesses in one: it supplies labour, it hires out kit it owns, and it carries tonnes of tube and board around on a lorry. Here is how CIS treats a contract that erects and hires at the same time, where the yard, the flatbed and the council's scaffolding licence go in your records, what happens to the 20% you take off your own gang, and a worked year for a sole trader with two operatives that ends in a refund.

What a self-employed scaffolder can claim
Tube, fittings, boards and ladder beams
Scaffold stock is equipment you keep and use, not something you sell, so a pallet of couplers, a bundle of 21-foot tube, fifty boards or a pair of ladder beams goes in Repairs and maintenance, the box HS222 gives equipment under the cash basis. The whole cost is deducted in the tax year you pay for it, so a firm that spends £9,000 restocking in a good year takes £9,000 off that year's profit. A secondhand lot bought from a firm that is closing counts the same way, and so do replacements for what comes back bent, split or not at all. Goods for resale is for the rare item you sell on and leave behind, such as sheeting the customer keeps.
Hiring kit in for the big one
When a job needs more than the yard holds, system scaffold, a loading bay, a hoist, extra boards or a rubbish chute from a hire company are Other expenses, with the delivery and collection charges. On a contractor job, kit you hire from someone else can come off the payment before the deduction is worked out, so put the hire charge on its own line of the invoice and keep the hire company's invoice with it.
The yard
Somewhere to stack the tube is a cost of trading. Rent for a yard or a corner of a compound goes in Rent, the rates if the council charges them in Business rates and council tax, and the electric for the lights and the container heater in Utilities. Pallet racking, a shipping container for the fittings, fencing and a camera over the gate are equipment in Repairs and maintenance, and so is the repair when the gate gets rammed.
Scaffolding licences, lights and barriers
Scaffold that stands on a public pavement or road needs the council's permission first, which councils generally call a scaffolding licence and charge for by the week or the month, often with a minimum level of public liability before they will issue it. The fee is an expense of the job, recorded as Other expenses, and so are the hazard lamps, cones, barriers and pedestrian tunnel the licence requires, and the scaffold alarm fitted overnight. The fine for scaffold on the highway without one is not.
Harnesses, helmets and the CISRS card
A full-body harness and its lanyards, a chin-strapped helmet, gloves, rigger boots and the hi-vis the site insists on protect you at height, so they are allowable, recorded as Other expenses, and the periodic inspection of the harnesses goes with them. Renewing your CISRS card, the health and safety test it needs and the refresher course the renewal asks for are costs of being let through the gate, and they go in Other expenses too. Spanners, podgers, a tape and a level are in Repairs and maintenance.
Insurance, the gang and the lorry's signwriting
Public liability at the level councils and main contractors ask for, cover for the stock in the yard and on the lorry, and employer's liability if you have anyone on the payroll are Insurance. Self-employed scaffolders you bring in and pay under CIS are recorded at the gross figure, before the 20% you take off, in Construction industry - payments to subcontractors; a labourer you employ is Wages and salaries. The accountant who files the monthly returns is Professional fees, and the banner with your name along the first lift, the lorry's signwriting and a website are Advertising costs.
The rules behind every claim: allowable expenses for sole traders.
The flatbed, the yard and the sites
A scaffolder's vehicle is usually a flatbed, a 3.5-tonne dropside or a 7.5-tonne lorry, and gov.uk lists goods vehicles alongside cars for the flat rate, with vans as its example, so a flatbed is within its wording. The choice is the same as for any trade vehicle and lasts as long as you run it: HMRC's flat mileage rates, 55p a mile for the first 10,000 business miles in the tax year and 25p after that, or the real costs of running it, diesel, insurance, the annual test, tyres, servicing and the tachograph calibration on a 7.5-tonner, in Motor and fuel. A lorry hauling two tonnes of tube burns diesel quickly, so it is worth doing both sums before settling on one. Buy one outright and the cash basis deducts the price in the year you pay for it, less any share for private use, after which that lorry stays on real costs for good; a car is never deducted in one go.
Which drives count depends on where the trade is run from. If the lorry lives at the yard and the day starts there, the yard is where the business is carried on, so your own drive from home to the yard is ordinary commuting, while the yard to each site, between sites, to the hire depot and back is business travel. A firm run from home, with the kit on a trailer or in a compound used for nothing but storage, treats the drive from home to each job as business travel instead. Scaffold goes up and comes down, so a year on one site is unusual, but a recladding contract where your kit stands round one block for most of a year can make that block the place the business is carried on and the drive to it a commute.
Keep the date, the site and the miles for each run, or the receipts for the diesel and the rest. FileThat prices a mileage entry at the flat rates, and a lorry on real costs takes a business-use percentage on each cost so only the business share reaches the return.

CIS and VAT
Erecting and striking scaffold is CIS
HMRC's guide to the scheme, CIS340, lists the erection or dismantling of scaffolding as a construction operation, and its manual files erecting under preparatory operations and dismantling under finishing ones. So when a builder, a roofer, a developer or a main contractor pays you to put a scaffold up and take it down, they take 20% off your labour, or 30% if you are not registered, and never off materials. Count the full amount before the deduction as income, and enter the figures from each contractor's monthly statement in FileThat so the tax taken counts against your bill at the end of the year.
Hire alone is outside; hire with erection is all in
The same guide lists the hire of scaffolding equipment without labour as outside the scheme, so a builder who collects tube and boards from your yard, erects them with their own people and pays you a weekly hire charge pays in full. The position changes the moment your gang erects it. CIS340 says that where one contract covers both construction and non-construction work, every payment under that contract is within the scheme, even when the two parts are on separate invoices, so splitting your bill into erection on one line and weekly hire on another does not take the hire out of the deduction. Check the contract before quoting, because the cash-flow difference between the two is the full 20% of the hire.
Your own scaffold is not materials or plant hire
The deduction leaves out materials you bought for the job and plant you hired in from a third party. Scaffold you own is neither. CIS340 is explicit that where the subcontractor owns the plant used on the work, no notional deduction for plant hire may be made, so on an erect-and-hire job built from your own stock the 20% comes off the whole payment, apart from anchors, resin, sheeting and the like bought for that job and anything hired in from a hire company. Show those on their own lines, or the contractor may estimate them and deduct on the rest. A homeowner wanting access to their own roof or chimney is never a contractor and pays in full, and a business outside construction, a shop or a block's managing agent, only becomes one after spending over £3 million on construction in any 12 months.
Your gang makes you a contractor, and VAT
Paying other scaffolders under CIS puts you on both sides of the scheme. Before the first payment you register with HMRC as a contractor and verify each person, then take 20% or 30% off what you pay them, give each of them a written statement within 14 days of the end of the tax month, and send HMRC a return every month by the 19th. FileThat records what you paid them; the return itself goes through HMRC's online service or your accountant. If you are VAT registered, erecting for a VAT-registered contractor under CIS normally falls within the domestic reverse charge, and those sales are recorded as Construction industry - reverse charge sales.

A scaffolding firm's year: two operatives, a flatbed and a yard
Take a sole trader scaffolder in England who, through 2026-27, erects and strikes scaffold for builders and roofers and receives £66,000 from them before deductions. The firm owns every tube and board it puts up, so no hire comes off, but the £350 of ties and sheeting it bought for those jobs is shown at cost on the invoices; the contractors deduct 20% of the other £65,650, £13,130, leaving £52,870 to reach the bank. Homeowners wanting access for a chimney, new windows or a roof repair pay in full: £14,000 over the year. Turnover is £80,000, which sits £10,000 under the VAT threshold, so the rolling twelve-month total needs checking at the end of every month.
Two self-employed operatives work the weeks there is work, paid under CIS. Each is paid £18,000, £36,000 together; the scaffolder takes 20%, £7,200, and sends it to HMRC on the monthly returns, so they receive £28,800 between them, and the whole £36,000 is the firm's cost. The rest of the year's spending: £4,200 of tube, fittings, boards and a pair of ladder beams, replacements for what went missing included; £900 hiring a loading bay and extra system scaffold for one homeowner's job; £3,600 of yard rent; £7,300 running the flatbed on real costs, diesel, insurance, the annual test, tyres and servicing, with no private use; £1,100 of council scaffold licences; £1,800 of insurance; £120 for CISRS renewals; £450 of harnesses, helmets, gloves and boots; £350 of ties, tags and sheeting; £300 for the work share of the phone; £600 for an accountant who also does the monthly returns; and £250 for signwriting and banners. The total is £56,970, so the profit is £23,030.
The Personal Allowance covers £12,570 of it, leaving £10,460 to tax. Income Tax at 20% is £2,092, Class 4 National Insurance at 6% is £627.60, and together the year's tax is £2,719.60. The contractors have already sent HMRC £13,130, so £10,410.40 comes back once the return is filed, and because far more than 80% of the tax was collected at source there are no payments on account for the following year. The £7,200 taken from the two operatives never enters this sum: it is their tax, held by HMRC against their own returns.
The refund is large because the 20% came off the hire value of the firm's own kit and the money that went straight out to the gang, not just the scaffolder's own labour. A firm with gross payment status has the same £2,719.60 to pay but nothing held: it falls due on 31 January 2028 along with the first payment on account of £1,359.80 towards 2027-28, £4,079.40 on the day, with the second £1,359.80 due by 31 July 2028. Record none of the £56,970 of costs and the tax on £80,000 would be £22,288.60, more than HMRC was holding. Scotland sets its own Income Tax bands, so a Scottish scaffolder's figures differ slightly.
What you cannot claim
Joggers under the harness
The harness, helmet, gloves and rigger boots are protective, so they count. The joggers, hoodie and trainers underneath are clothing you could wear anywhere, and they stay private however many tubes they have been dragged across, unless they carry the firm's name.
Breakfast from the van at the yard
A bacon roll and a tea at the yard before loading up is breakfast, which you would have bought whether or not you were working, so it stays private. Meals become allowable when the work takes the gang away overnight, a contract two hours up the motorway with digs for the week.
Scaffold round your own house
Putting the firm's scaffold up for your own roof, or lending the gang to your brother's extension for nothing, is private use. The operatives' pay for those days, the diesel, and any licence fee are recorded and marked disallowable so they never reduce the profit.
Fines, overweight tickets and drawings
A fine for scaffold on the pavement without a licence, a penalty for an overloaded lorry, a parking ticket outside the job, interest on tax paid late and the money you draw for yourself are not expenses of the firm, and nor are the Income Tax and Class 4 on the profit.
Where each line is drawn: harnesses and what you wear under them, meals on site and away and the lorry, fines and tolls.
Straight answers
Is scaffold hire subject to CIS?
Not on its own. HMRC's CIS340 lists the hire of scaffolding equipment without labour among the operations outside the scheme, so a builder who hires tube and boards from you and erects them with their own people pays you in full. Once your firm erects the scaffold, erection is a construction operation, and CIS340 says a contract covering both construction and non-construction work brings every payment under it within the scheme, separate invoices or not. In that case the deduction applies to the hire element too, and because you own the kit there is no plant hire to take off first.
Can I claim tubes, boards and fittings I buy?
Yes, in full in the year you pay for them. Scaffold stock is equipment kept and used in the business, which the cash basis treats as a normal expense rather than something written off over years, recorded as Repairs and maintenance. A big restock can turn the year into a loss, and a cash basis loss can be set against your other income or carried forward against later profits, so the deduction is not wasted. Secondhand stock bought from a firm that is closing down is claimed the same way, as is every replacement for a board that split or a fitting that never came back.
Is a council scaffold licence tax deductible?
Yes. Scaffold on a public pavement or road needs the highway authority's permission, and the fee the council charges for it, whether a flat sum for the first weeks or a weekly rate for as long as the scaffold stands, is a cost of that job, recorded as Other expenses along with the lamps, barriers and pedestrian tunnel it requires. If you charge the fee on to the customer, what they pay you is income and the fee is the expense against it. A fine for standing scaffold on the highway without the licence is a penalty, and penalties are never allowable.
Can I use the flat mileage rate for my flatbed lorry?
Gov.uk makes the flat rate available for goods vehicles, giving vans as its example and excluding only cars built for commercial use such as black cabs, and a flatbed carrying your tube is a goods vehicle. Two things narrow it. If you have already deducted the lorry's purchase price as an expense, or claimed capital allowances on it, gov.uk says the flat rate is not available for that vehicle, so it is on real costs for good. And once you choose the flat rate for a vehicle you keep it for as long as you use that vehicle in the business, so work out which method gives more over the years you expect to run the lorry before the first return claims it.
Kit goes missing or comes back damaged. What can I do about it?
Replacing it is the claim. You deducted the original tube, boards and fittings in the year you bought them, so there is nothing left to write off when they disappear or bend; the replacements are a new purchase, recorded as Repairs and maintenance when you pay for them. If a customer or a contractor pays you for boards they lost, or your insurer pays out after a theft from the yard, that money is income of the business and belongs in your records, not against the replacement cost. Keep a note of the losses: a yard count at the end of each job is also how you know what to bill for.
I take 20% off my two operatives. Does that come back to me when I file?
No. The 20% you deduct from the people you pay is their tax, sent to HMRC on their behalf through your monthly return, and it counts against their bills when they file their own returns. Your refund, if there is one, comes only from the deductions contractors took from what they paid you. Paying them under CIS does make you a contractor: register as one before the first payment, verify each operative, give each of them a written statement within 14 days of the end of every tax month, and send the return by the 19th through HMRC's online service or your accountant. The gross amount you pay them is your expense, in Construction industry - payments to subcontractors.
Do self-employed scaffolders have to use Making Tax Digital?
Yes, once your qualifying income is over the threshold. It has been £50,000 since 6 April 2026, and falls to £30,000 from April 2027 and £20,000 from April 2028. Qualifying income is turnover before anything comes off, so for a scaffolding firm it is the full amount contractors paid before CIS, the hire element of your own kit and the share that went straight out to the gang included, plus any property income. HMRC reads it from a return you have already filed, so a year like the worked example brings the firm in from a later April rather than the year it happens.
