Allowable expenses, van and equipment costs, CIS deductions, VAT and MTD for Income Tax explained for UK self-employed fascia, soffit and exterior cleaning specialists.
Cleaning fascias, soffits, bargeboards and gutters is a low-overhead, high-ladder trade. The work is straightforward: restore yellowed, algae-stained uPVC back to bright white, clear the gutters, and move to the next 1930s semi on the round. The tax, though, has a few wrinkles that trip up exterior cleaners specifically: whether the Construction Industry Scheme bites, how to handle a van and a load of working-at-height kit, and how to keep records when most jobs are cash-or-card domestic one-offs booked the same week.
This guide is built around how a fascia and soffit cleaner actually earns and spends: a vehicle full of equipment, a mix of domestic customers and the occasional contractor job, and seasonal demand that peaks in spring and after winter storms. Get the expenses and the CIS position right and you will rarely overpay.
As a sole trader you pay Income Tax on your profit, which is your cleaning income minus allowable expenses. For 2025/26 the personal allowance covers the first GBP 12,570, then you pay 20% to GBP 50,270, 40% to GBP 125,140 and 45% above, with the personal allowance tapering away between GBP 100,000 and GBP 125,140 to create an effective 60% band. Class 4 National Insurance is 6% on profit between GBP 12,570 and GBP 50,270 and 2% above, while Class 2 NIC is settled through Self Assessment and protects your State Pension record.
Scottish cleaners pay Scottish Income Tax through six bands (19%, 20%, 21%, 42%, 45% and a 48% top rate) and carry an S-prefixed tax code, though National Insurance stays UK-wide. Welsh cleaners have a C-coded tax code at rates currently matching the rest of the UK. If you also hold a part-time PAYE job and your code looks wrong, run it through the tax code checker so you are not over- or under-taxed on the employment side.
Plenty of cleaners start with a ladder and a bucket at weekends before going full-time. The GBP 1,000 trading allowance is built for that. If your gross cleaning income from all self-employed work is GBP 1,000 or less in a tax year, it is tax-free and you do not need to register for Self Assessment. Cross GBP 1,000 and you must register and report the full amount.
Once you are over the threshold you choose each year: deduct the flat GBP 1,000 trading allowance instead of working out actual expenses, or deduct your real allowable costs if they come to more. You cannot do both. For a fascia cleaner the actual-cost route almost always wins, because a van, ladders, a water-fed pole kit and fuel easily exceed GBP 1,000 in any working year. The flat allowance only suits a very occasional weekend cleaner with borrowed kit.
This is the part exterior cleaners most often get wrong. The Construction Industry Scheme governs payments between contractors and subcontractors for construction operations. Pure window or fascia cleaning for a homeowner sits outside CIS, and they pay you the full agreed price. But the moment you subcontract to a building firm, roofer, scaffolder or property maintenance contractor, and your fascia, soffit and bargeboard work forms part of construction, renovation or refurbishment, CIS can apply.
Under CIS the contractor deducts money from your labour before paying you and hands it to HMRC: 20% if you are registered as a subcontractor, or 30% if you are not. Materials are excluded from the deduction. Crucially, these deductions are advance payments against your tax bill, not a final tax. Because the 20% rate is often more than your actual liability once expenses and your personal allowance are taken into account, most CIS subcontractors are owed a refund at year end.
Register as a CIS subcontractor to drop from 30% to 20%, keep every payment-and-deduction statement, and read our full guide to CIS for subcontractors before you take contractor work. You can estimate the refund with the CIS tax calculator.
An expense is allowable when incurred wholly and exclusively for the business. This is an equipment- and vehicle-heavy trade, so your deductions are dominated by the van and the kit rather than software or an office.
| Expense | What qualifies | Notes |
|---|---|---|
| Van and vehicle | Mileage at 45p/25p per mile, or actual running costs (fuel, insurance, tax, repairs, MOT) | Pick one method per vehicle and stick with it |
| Access equipment | Ladders, ladder stays and stand-offs, scaffold towers, roof ladders | Larger items via the Annual Investment Allowance |
| Water-fed pole systems | Telescopic poles, pure-water tanks, pumps, hose reels, DI/RO filtration | A core asset, usually claimed in full as AIA |
| Cleaning equipment | Pressure washer, brushes, surface cleaners, buckets, squeegees | Replaceables are ordinary running costs |
| Materials and chemicals | uPVC restorer, soft-wash solutions, algae and mould treatments, pure water | Fully deductible job consumables |
| PPE and safety | Harnesses, hard hats, gloves, goggles, non-slip boots, hi-vis | Genuine protective gear is allowable; everyday clothes are not |
| Insurance | Public liability, working-at-height cover, tools-in-transit, van insurance | Essential and fully deductible |
| Workwear and branding | Branded uniform, van sign-writing and wrap, leaflets | Branding and sign-writing are allowable; plain everyday clothing is not |
| Phone and admin | Business share of mobile, booking app, a fair home-office proportion | Apportion out private use |
| Marketing | Website, local ads, Google listing, leaflet drops, customer review tools | Fully deductible running costs |
| Professional fees | Accountancy, bookkeeping, business banking | Fully deductible |
Your sign-written van is usually your biggest single deduction, so choose your method carefully. You can claim simplified mileage at 45p per business mile for the first 10,000 miles and 25p thereafter, which needs only a mileage log and no fuel receipts. Or you can claim the actual running costs (fuel, insurance, road tax, servicing, repairs, MOT) plus capital allowances on the van itself, scaled to the business-use proportion. For a cleaner driving a heavy, kit-laden van across a wide round, the actual-cost method often gives a larger deduction, but once you choose a method for a vehicle you must keep to it until you change the vehicle. Work it out both ways once and use the winner.
The private share of your van, phone and fuel must be excluded. Everyday clothing is never allowable even if you only wear it for work. Parking fines and speeding penalties are not deductible. And the cost of getting set up before your trade actually began, such as your first round of equipment, is pre-trading expenditure that is claimed once you start trading rather than lost.
Most fascia cleaning is domestic, booked at short notice and paid by card, bank transfer or cash on the day. That is exactly where income slips through the cracks. Record every job as it is done, not at the end of the month: the customer, the date, the price, and how they paid. A simple phone app or spreadsheet beside the van is enough. Keep all equipment, fuel and chemical receipts, photograph paper ones before they fade, and file contractor CIS statements separately. Good daily capture turns the annual return into a formality and protects you if HMRC ever asks how a cash figure was reached.
Take a sole trader running a one-van domestic fascia, soffit and gutter round, billing GBP 42,000 over the year, with no CIS work.
Income: GBP 42,000
Allowable expenses:
Taxable profit: GBP 42,000 minus GBP 14,700 = GBP 27,300
Income Tax: GBP 27,300 minus GBP 12,570 = GBP 14,730 at 20% = GBP 2,946
Class 4 NIC: GBP 14,730 at 6% = GBP 884
Total Income Tax and Class 4 NIC: GBP 3,830 for the year, plus Class 2 NIC through Self Assessment. Run your own figures through the sole trader tax calculator to sanity-check what to set aside. Had any of this work been CIS subcontract labour, the 20% already deducted at source would be credited against this bill and likely produce a refund.
For an exterior cleaner, the van and the kit are your biggest tax savers, but the unrecorded cash job is your biggest tax risk. Log every job as you finish it and keep every receipt.
You must register for VAT once taxable turnover exceeds GBP 90,000 in any rolling 12-month period. A solo cleaner rarely gets there, but a round that grows to two or three vans and a small team can. The catch for this trade is that most of your customers are homeowners who cannot reclaim VAT, so charging 20% either squeezes your margin or pushes your prices up against unregistered rivals. Voluntary registration mainly pays off if you take a lot of contractor or commercial work where clients reclaim, or if you are about to spend heavily on a new van and water-fed pole system and want to reclaim the VAT on it. Most domestic-only cleaners are better off staying under the threshold.
Making Tax Digital for Income Tax Self Assessment replaces the annual return with quarterly digital submissions and a year-end finalisation. The thresholds are based on gross income, not profit:
Because the test is on turnover, a busy single-van round can cross the GBP 50,000 line even when profit after van, kit and fuel is far lower, so check your gross takings, not your profit. In practice MTD suits this trade well: recording each job digitally as it is done, instead of reconstructing a year of cash-and-card jobs every January, is far less painful. Our guide to MTD for sole traders walks through the quarterly rhythm.
Not registering once over GBP 1,000. The trading allowance is a threshold, not a free pass. Cross it and you must register for Self Assessment, even if cleaning is a weekend sideline.
Treating turnover as taxable income. You are taxed on profit. Forgetting to claim the van, ladders, chemicals and insurance leaves you paying tax on money you never kept.
Missing CIS refunds. If contractors deducted 20% from your labour, that is tax already paid. File and reclaim it rather than leaving the refund with HMRC.
Choosing the wrong van method. Switching between mileage and actual costs on the same vehicle is not allowed, and the wrong choice can cost hundreds a year. Compare both before you commit.
Losing cash jobs. Domestic cash work is easy to under-record and is exactly what HMRC scrutinises. Log every job the day you do it.
