If you're in construction, you're probably leaving money on the table. From tools to transport to site-related costs, here are the most overlooked tax deductions UK builders can claim to reduce their bill — legally.
Power tools, drills, ladders, helmets, gloves — if it’s essential for the job, it’s likely deductible. Don’t forget wear and tear or replacements, especially if you’re buying frequently. Keep those receipts.
Whether you own a van or use your personal car, you may be able to deduct mileage, insurance, MOT, repairs and fuel — especially if the vehicle is used primarily for your construction business. Mileage logs matter.
Timber, cement, sealants, screws, sandpaper, site tape, gloves — the list of consumables builders go through is long. As long as they’re job-related, they count. Even materials used on your own house may be claimable if it’s a show/demo build.
Your work phone bill, accounting software, project quoting apps, email tools, and cloud storage (like Google Drive, OneDrive or Dropbox) are all tax-deductible if used for business. If in doubt, claim a portion that reflects usage.
If you hire subcontractors, payments made under the Construction Industry Scheme (CIS) count as allowable expenses. So do payroll systems, verification tools, or outsourced help with filings. Keep everything recorded and reconciled.
Builders work hard. So should your tax return. Start keeping records now, and make sure you claim every allowable expense when the time comes. It’s your money — don’t leave it behind.
