Security Guard Take-Home Pay Calculator 2026

From £14.00 an hour to a yearly figure

The conversion is hourly rate × weekly hours × 52, and the hours are what moves the answer. £14.00 at 37.5 hours is £27,300 a year. At 40 hours it is £29,120. At 42 hours — the 4-on-4-off average — it is £30,576. At 48 hours it is £34,944. Same median rate, four different salaries: the hours are the pay offer as much as the rate is.

Through the 2026/27 England model with auto-enrolment on, those gross figures become monthly take-home of £1,868.12 at 37.5 hours, £1,971.86 at 40 hours, £2,054.85 at 42 hours and £2,303.83 at 48 hours. These are engine-computed, not estimated — and they assume every hour is at the basic rate. Night premiums and overtime are separate additions, handled below.

Use the same conversion on job adverts in reverse. A £30,000 salary on a 48-hour rota is £12.02 an hour — below the £12.71 National Living Wage and below the £14.00 median. A £30,000 salary on a 42-hour 4-on-4-off rota is £13.74 an hour — under the median, but legal. The advert quotes the figure that flatters the rota; divide it down to the hour before you compare it to anything.

Twelve-hour shifts and 4-on-4-off: what the pattern pays

Twelve hours at £14.00 is £168 a day — the unit the trade thinks in. Four shifts on, four shifts off means four £168 days in every eight-day cycle: £672 per cycle, £588 a week on average, £30,576 a year. That is the plain pattern, no premium, no overtime, and it already beats the £27,300 baseline by £3,276 a year — the 4.5 extra hours a week doing all the work.

The part-time version is just as common in retail guarding: three 8-hour days at £14.00 is £336 a week, £17,472 a year. Run that through the calculator and the monthly take-home is £1,307.92 — the deductions bite less because the £12,570 personal allowance covers a bigger share of a smaller gross. Part-time guards keep proportionally more of what they earn.

Whatever the pattern, enter the annual gross — rate × hours × 52 — not the shift figure. The calculator does not know what a shift is; it only knows the year's pay, and the year's pay is what the taxman sees.

Night premium maths

A night premium turns the hourly rate into an effective rate, and the effective rate is what goes in the calculator. £14.00 plus a typical £1.50 premium is £15.50 an hour: at 42 hours a week that is £33,852 a year gross, and the monthly take-home on it is £2,241.58 — £186.73 a month more than the same 42 hours on days. The premium is wages like any other: income tax, National Insurance and pension all apply, so there is no shortcut that puts it in untaxed.

Stacking matters where overtime meets nights. A guard on £15.50 nights who does overtime at time and a half gets the 1.5 multiplier on the night rate — £23.25 an hour — not on the £14.00 day rate, unless the contract says otherwise. Eight overtime hours a fortnight at £23.25 is £4,836 a year of gross: add it to the £33,852 base and the calculator works on £38,688. Check the contract for which rate the multiplier applies to; the difference is £3 an hour.

One more check before you bank the premium: it has to be in the contract or the offer letter. A premium paid 'at the company's discretion' can be withdrawn in a quiet quarter, and a take-home budget built on it falls apart with it.

Working the doors on your own account

Plenty of door supervisors are not employees at all: they work the doors as self-employed contractors, invoicing venues or agencies per night. The tax maths is a different machine. Income tax is paid through self-assessment rather than PAYE; National Insurance is Class 2 and Class 4 rather than Class 1; there is no auto-enrolment pension unless you set one up yourself; and allowable expenses — the SIA licence fee, the training course, travel between venues — come off the income before tax is charged.

That is why this calculator cannot model self-employed door work: every line of the worked example assumes an employer deducting PAYE. Running a self-employed income through it misstates the National Insurance, invents a pension that does not exist, and ignores the expenses. The ONS median does not include the self-employed either — ASHE covers employees only — so even the £14.00 anchor describes the employed trade.

The brief version of the comparison: employed guards get continuity, paid holiday and an employer pension contribution, and pay Class 1 National Insurance; self-employed door supervisors keep the expenses, set their own nightly rate, and carry the quiet weeks. Same doors, different tax systems.

The Scotland toggle and the higher-rate boundary

North of the border the income tax bands are Scotland's own — six thresholds running from 19% to 48% — while National Insurance and the £12,570 personal allowance work the same UK-wide. At the £27,300 baseline the Scottish bands are a touch kinder than England's flat 20%: the 19% starter band means a Scottish guard takes home £1,871.43 a month against England's £1,868.12. Small, real, and applied automatically by the nation toggle under the calculator.

The boundary that matters more is the 40% threshold at £50,270. A guard would have to work hard to reach it — £14.00 an hour needs nearly 69 hours a week, every week — but the long-hours end of the trade gets closer than it looks: 60-hour weeks are £43,680 a year, and with night premiums and regular overtime a heavy rota can push toward £50,000. Above £50,270 every extra pound is taxed at 40% instead of 20%. The calculator handles the crossing automatically; it is worth knowing the line is there before a heavy-overtime year lands you over it.

How the tax engine works

The worked example runs the £27,300 median through the 2026/27 England model in deduction order. First the pension: 5% of qualifying earnings (£27,300 minus the £6,240 lower limit = £21,060), which is £1,053.00. The model is salary-sacrifice: income tax and National Insurance are charged on pay after the pension comes out, so £27,300 − £1,053.00 = £26,247.00 of taxable pay. Income tax is 20% of pay above the £12,570 personal allowance: (£26,247.00 − £12,570) × 20% = £2,735.40. Employee National Insurance is 8% between £12,570 and £50,270: (£26,247.00 − £12,570) × 8% = £1,094.16. Subtract all three from £27,300 and the take-home is £22,417.44 — £1,868.12 a month, £431.10 a week. Every figure in the worked example is engine-computed, not estimated.
