What UK software engineers earn at every level in 2026, nationally and in London — with the take-home figure recruiters never mention.
The UK median software engineer salary sits around £55,000–£58,000 in 2026, but the spread is enormous: seniority, London vs regional, and product companies vs agencies all move the number by tens of thousands. The table shows representative salaries at each level with the after-tax reality — note how the £100k+ Staff level runs into the 60% tax trap.
| Level | Typical salary | Take-home / year | Take-home / month |
|---|---|---|---|
| Junior (0–2 yrs, national) | £33,000 | £27,280 | £2,273 |
| Junior — London | £39,000 | £31,600 | £2,633 |
| Mid-level (3–5 yrs, national) | £55,000 | £42,457 | £3,538 |
| Senior — national | £75,000 | £54,057 | £4,505 |
| Senior — London | £95,000 | £65,657 | £5,471 |
| Staff / Principal — London | £120,000 | £75,914 | £6,326 |
Take-home figures use 2026/27 England/Wales/NI rates (Income Tax + employee NI only, standard tax code, no pension or student loan deductions). Public-sector pension contributions will reduce take-home further — model yours with our Pension Tax Relief Calculator.
London salaries run 30–40% above national averages, and US-headquartered firms and fintechs pay far above even that — total compensation at top firms can exceed £150k–£250k with equity. Equity (RSUs) is taxed as income when it vests, so a big vest can push you over £100,000 and into the personal allowance taper without warning.
Day rates of £450–£700 are common for senior contractors, but IR35 status changes everything: inside-IR35 via an umbrella loses a large slice to employer NI and fees. Compare properly with our IR35 Calculator and Umbrella Pay Calculator before jumping.
Around £55,000–£58,000 median nationally. Juniors typically start at £28,000–£38,000; seniors earn £70,000–£95,000+, and considerably more in London or at US tech firms.
Roughly £64,912 a year — about £5,409/month — after tax and NI at 2026/27 rates, before pension contributions.
Between £100,000 and £125,140 the personal allowance tapers away, creating an effective 62% marginal rate including NI. Pension salary sacrifice is the standard fix — see our £100k tax trap guide.
An outside-IR35 day rate of £550 can significantly out-earn a £95k salary, but inside-IR35 umbrella work often doesn't. Run both scenarios in our IR35 calculator first.
