Are the gas engineer presets official salary statistics?

No. Unless a particular source and effective date are explicitly identified, role labels and prefilled amounts are editable planning examples, not verified market medians, an employer pay award or an individual entitlement. Use your current contract, pay statement or actual business records.

Why might the result differ from my payslip or tax return?

This is an annual estimate. Actual results depend on your UK jurisdiction, tax code, pension method, pensionable earnings, loan notices, other income and the timing of payments. Payroll rounding, arrears, benefits and irregular pay can change the result. A self-employed or partnership arrangement also needs its own profit and National Insurance treatment.

Does a professional fee or expense always reduce my tax?

No. Check the applicable HMRC conditions, the amount you actually paid and whether your employer reimbursed it. A deduction normally reduces taxable income rather than producing a pound-for-pound repayment. Do not claim the same cost twice.

What matters in this pay comparison?

Employed rota pay versus call-out business profit

Separate contractual salary, standby pay and paid call-outs. In a self-employed comparison, include only realistic billed work and allowable van, equipment and registration costs.

Employment status and CIS treatment depend on the work and arrangement. The presence of a day rate or trade registration does not settle those questions.

Check the basis before comparing offers

Use the same year, working hours and paid weeks. An hourly rate, full-time equivalent salary, day rate and actual annual receipts are different inputs.
Check pension method and pensionable pay. Net-pay pensions generally reduce Income Tax but do not reduce employee NI or student-loan earnings; salary sacrifice can affect all three.
Separate cash received from non-cash benefits, reimbursements and deferred awards. Eligibility for a tax deduction is a separate question from whether a payment is taxable.

A reproducible reference calculation

This is an illustrative annual employment salary of £45,000.00, not a typical salary for this occupation or the specialist calculator’s default. It assumes England, Wales or Northern Ireland, the standard Personal Allowance, no other income, no pension contribution and no student loan.

Annual gross salary: £45,000.00
Income Tax: £6,486.00
Employee National Insurance: £2,594.40
Annual net estimate: £35,919.60
Monthly average: £2,993.30

Increasing the annual salary by £1,000 in this reference case increases annual net income by £720.00. This change is calculated from both complete estimates, so it captures any allowance taper or tax-band crossing.

The reference uses annualised employee NI thresholds. Your actual pay-period NI and payroll rounding can differ. Scotland requires its devolved Income Tax calculation.

Sources and checks for your own contract

Use the tax sources for the calculation rules and the role or scheme authority for the applicable working arrangement. A link to tax guidance does not verify an employer salary, a market median or every preset.

Rates are labelled for 2026/27; pay awards and scheme rules can have different effective dates. For a discrepancy, send the page and calculation assumptions to our corrections contact.
