Demolition is construction work that falls under the Construction Industry Scheme (CIS). If you work as a self-employed demolition operative, your contractor deducts 20% from your payments and sends it to HMRC. At the end of the tax year, you file Self Assessment — and the expenses you claim often mean a significant refund.
Demolition workers face higher costs than most construction trades — insurance premiums are significantly higher due to the risk profile, asbestos awareness training must be renewed every year, and CCDO cards are mandatory for site access. Every one of those costs is deductible.
What You Can Claim
| Expense | Examples | Typical Annual Cost |
|---|---|---|
| Insurance | Public liability (demolition-specific, from ~£2,240/year for £5M cover) | £2,000–£3,000 |
| CCDO card & training | CCDO card renewal, NVQ Level 2 Demolition assessment (~£600–£850) | £100–£900 |
| Asbestos awareness | Annual renewal — UKATA/NDTG approved (~£15–£30/year) | £15–£30 |
| Hand tools | Wrecking bars, pry bars, sledgehammers, bolster chisels, nail pullers | £100–£300 |
| Power tool hire | Kango breaker (~£35–£50/day), SDS drill, angle grinder, reciprocating saw | £500–£2,000 |
| PPE & workwear | Steel-toe boots, hard hat, FFP3 dust masks, ear defenders, safety goggles, hi-vis | £200–£500 |
| Vehicle costs | Van fuel, insurance, MOT, servicing, road tax | £4,000–£6,000 |
| Skip hire & waste disposal | Skip hire for demolition waste (~£200–£400 per skip) | £500–£2,000 |
| Phone & apps | Mobile contract (business portion), job management apps | £150–£300 |
| Accounting fees | Tax return preparation, bookkeeping | £150–£400 |
Insurance: Your Biggest Fixed Cost
Demolition insurance is 10–15 times more expensive than standard construction cover. A sole trader typically pays £2,000–£3,000/year for public liability at the £5M level most sites require. This is fully deductible — and it's often the single largest expense after vehicle costs.
CCDO Cards: Not CSCS
Demolition operatives use the CCDO (Certificate of Competence of Demolition Operatives) system, not the standard CSCS cards used by other trades. Green Labourer cards require the HSE Touch Screen Test plus an Asbestos Awareness certificate. Blue Operative cards require NVQ Level 2 in Demolition (~£600–£850). All card and training costs are deductible.
Asbestos Awareness: Renewed Every Year
Unlike most certifications that last 3–5 years, asbestos awareness must be renewed annually. The course costs £15–£30 and must be UKATA, NDTG, ARCA, or ACAD approved. It's a small but recurring annual deduction.
HMRC Flat Rate Alternative
HMRC allows a £60/year flat rate deduction for tools and specialist clothing. For demolition workers, FFP3 masks and boots alone exceed this — claim the real figures with receipts.
Expenses You Can't Claim
- Commuting to a regular site — travel to the same location for over 24 months isn't deductible. Travel between different demolition sites is deductible
- Everyday clothing — jeans and hoodies don't qualify. Only specialist PPE counts (FFP3 masks, hard hats, safety boots)
- Your original demolition qualification — your first NVQ or CCDO training course isn't deductible. Only renewals, upgrades, and annual asbestos refreshers count
- Fines and penalties — HSE fines, parking tickets, late-filing penalties
- Food and drink — unless you're working away from your normal area overnight
Example: How Much Tax Does a Demolition Worker Pay?
Mike works as a self-employed demolition operative through CIS. Here's his 2025/26 tax year:
| Item | Amount |
|---|---|
| CIS income (gross) | £38,000 |
| CIS deducted (20%) | £7,600 |
| Allowable expenses | £8,000 |
| Taxable profit | £30,000 |
| Income Tax (after £12,570 personal allowance) | £3,486 |
| Class 2 NI (£3.50/week × 52) | £182 |
| Class 4 NI (6% on £12,570–£50,270) | £1,046 |
| Total tax + NI due | £4,714 |
| CIS already deducted | £7,600 |
| Refund due | £2,886 |
Without claiming expenses, his refund would be just £806. Expenses — led by insurance and equipment hire — save Mike £2,080. You can claim back your CIS deductions through your Self Assessment return.
Record Keeping Tips
- Save your insurance renewal document — at £2,000+/year, this is your largest fixed deduction. Keep the policy confirmation and payment receipt each year
- Keep your asbestos awareness certificate — this annual renewal is both a legal requirement and a deductible expense. Store the certificate with your tax records
- Track breaker and plant hire invoices — Kango hire, mini digger hire, and skip charges are large, easy-to-prove deductions. Keep every invoice with the job address and dates
- Save your CIS payment statements — you need these to reclaim the 20% deduction. Chase your contractor for missing ones before January
- Log PPE replacement dates — FFP3 masks, boots, and gloves wear out fast in demolition. A log of replacement purchases supports your claim if HMRC queries amounts
