Mid-Level Software Engineer Salary UK 2026/27
ONS does not split software developers by seniority, so a mid-level engineer is best read against the middle of the group. For programmers and software development professionals (SOC 2020 2134) the full-time median was £56,914 in ASHE 2025, with a lower quartile of £42,289 and an upper quartile of £75,794. The median is above the £50,270 higher-rate threshold.

What influences mid-level software engineer pay
The figures here are percentiles of the whole software development occupation, not a measurement of mid-level roles. Employer and specialism move pay more than years served, which is why the middle half of the group spans £42,289 to £75,794. Contracting through a limited company is the other route, and IR35 decides whether an engagement is taxed much like employment.
Crossing £50,270 means every extra gross pound is taxed at 40% IT + 2% NI = 42%. A 5% salary sacrifice pension becomes materially more attractive here, saving 42p in the £ at marginal.
Packages can include employer pension contributions above the auto-enrolment minimum, private medical cover and share options or RSUs, none of which is in the salary figure. Each 1% of salary an employer pays into the pension is worth £569 a year at the £56,914 median.

Frequently asked questions
- At £55,000 gross, should I max pension sacrifice?
- Sacrificing down to £50,270 saves 42% (IT+NI) on every pound in that band - £1,000 sacrificed costs you £580 in take-home but adds £1,000 to pension. Hard to beat that from taxed post-tax investment.
- Do engineering managers earn more than software engineers in the UK?
- Not at the median on ONS figures. In ASHE 2025 the full-time median for IT managers (SOC 2020 2132), where software engineering managers are coded, was £56,438, against £56,914 for programmers and software development professionals (SOC 2020 2134). At the 90th percentile it was £97,048 for IT managers and £102,860 for developers.
