Pay for a self-employed builder in the UK ranges roughly £28,000-£35,000 for a builder working alone on smaller domestic jobs up to £60,000 or more for an established builder running larger projects or a small team of subcontractors, depending on experience, location, and how established the business is. Taking a representative self-employed profit of £42,000 for 2026/27: taxable income after the £12,570 Personal Allowance is £29,430, all within the 20% basic rate band, giving £5,886.00 Income Tax. Class 4 National Insurance is charged at 6% on profit between £12,570 and £50,270, coming to £1,765.80. Combined deductions of £7,651.80 leave £34,348.20 take-home pay a year, around £2,862.35 a month. Self-employed builders working on construction sites for a contractor are usually paid gross under the Construction Industry Scheme (CIS) rather than having tax deducted at source, or have 20-30% deducted under CIS if registered/unregistered, which is later reconciled against the actual Income Tax and Class 4 National Insurance due through Self Assessment -- many builders end up due a refund once genuine business expenses (tools, van costs, materials, insurance) are deducted from gross CIS income to arrive at taxable profit.
