When you hire a developer UK market data from 2020 is already out of date. If you are a woman founder building a tech product or digitalising your operations, you need accurate figures for 2026, not outdated salary tables. You also need to know whether the gender pay gap in UK tech affects what you should offer, and how to avoid building unequal pay into your team from day one.

This guide sets out current UK developer costs, the latest gender pay gap data for the technology sector, and practical steps to set fair, competitive salaries.

What UK businesses pay for software developers in 2026

Developer salaries vary sharply by seniority, location, and whether you hire a permanent employee or a contractor. According to Reed’s 2026 salary guide, the average software developer salary in the UK ranges from approximately £35,000 for junior roles to £75,000 or more for senior positions. London premiums push these figures higher, with mid-level developers commonly earning £55,000 to £75,000 and senior specialists in high-demand areas such as AI, cloud architecture, or cybersecurity commanding £80,000 to £120,000.

Glassdoor and Indeed data from 2026 broadly align: the median software developer salary in the UK sits around £45,000 to £55,000, while lead developers and engineering managers can exceed £90,000. These figures represent base salary only. On top of base pay, employers must budget for employer National Insurance contributions, pension auto-enrolment, software licences, equipment, and recruitment fees, which typically add 15% to 25% to the headline cost.

If you hire a contractor instead of an employee, expect day rates from £400 to £800 for experienced UK developers, with specialist contractors charging £1,000 or more per day. Before you engage a contractor, check whether the off-payroll working rules, known as IR35, apply. Getting this wrong can leave your business liable for unpaid tax and National Insurance. Our IR35 Off-Payroll Working UK guide explains what women founders need to know.

The gender pay gap in UK tech

The gender pay gap in the UK technology sector remains wider than the national average. According to the Office for National Statistics, the median gender pay gap for full-time employees across all UK industries was 7.3% in April 2024. However, data from the Tech Talent Charter’s 2024 report shows that women hold only around 26% of tech roles in the UK, and the gender pay gap within technology companies is closer to 12% to 16% depending on role and seniority.

The gap is not simply about women being paid less for the same job title. It is driven by occupational segregation, fewer women in senior engineering and leadership roles, and unequal progression. The Fawcett Society notes that women are under-represented in higher-paid technical specialisms and over-represented in lower-paid digital support roles. This matters for your business because if you copy market rates without scrutiny, you may inherit the bias embedded in those rates.

For businesses with 250 or more employees, gender pay gap reporting is mandatory. You must publish data on the difference between men’s and women’s average hourly pay, bonus pay, and the proportion of men and women in each pay quartile. Even if your business is below the threshold, publishing a voluntary report can strengthen your employer brand and help you spot problems early. Our Gender Pay Gap Reporting 2026 guide covers the current rules.

Why pay parity matters when you hire

Paying developers fairly is not only a legal and ethical issue. It is a commercial one. Research by McKinsey and others consistently shows that diverse teams, including gender-diverse engineering teams, perform better on innovation, problem-solving, and product development. If women discover they are underpaid relative to male colleagues, retention falls and recruitment costs rise.

For early-stage businesses, the risk is particularly acute. Start-ups often hire quickly, use informal pay-setting, and rely on the founder’s network. That approach can reproduce market inequalities. A woman founder who sets transparent pay bands from the first hire is less likely to face a costly correction later, as Salesforce famously had to do when it spent millions of dollars adjusting salaries to close unexplained pay gaps.

How to hire a developer UK and set fair pay

Use these practical steps to set competitive, equitable salaries when you hire a developer.

1. Benchmark against UK sources. Use UK salary guides from Reed, Hays, Robert Walters, or IT Jobs Watch rather than global averages. Adjust for your region; London, Manchester, Bristol, and Edinburgh all have different market rates.
2. Define pay bands before you advertise. Set a salary range for the role based on skills, experience, and responsibilities, not on the candidate’s previous salary or negotiation confidence. Advertising the salary is now expected practice and helps close gender gaps.
3. Do not ask about previous salary. Relying on past pay perpetuates historical discrimination. Instead, ask what the role is worth to your business.
4. Audit starting salaries by gender. When you have more than a handful of employees, check whether men and women joining similar roles receive comparable offers. Small differences at hire compound over time.
5. Be transparent about progression. Women in tech often leave mid-career because progression paths are unclear. Publish the criteria for promotion to senior developer, lead, or engineering manager.
6. Review contractor rates too. If you use contractors, check that day rates reflect skill and experience rather than gender. IR35 compliance and fair pay are separate issues, but both protect your business.

Practical steps for fair developer hiring

• Check current UK developer salary benchmarks for your region and role level before writing a job advert.
• Set a published salary range and avoid asking candidates about their previous pay.
• Build a simple pay audit into your annual review process once you employ staff.
• If you have 250 or more employees, prepare your gender pay gap report in line with the 2026 deadline.

Final thoughts on fair developer pay

When you hire a developer UK salary costs in 2026 will typically fall between £45,000 and £75,000 for a permanent mid-level role, and significantly more for senior specialists or London-based hires. The gender pay gap in UK tech remains around 12% to 16%, so women founders must be deliberate about fair pay from the first hire. By benchmarking against UK data, advertising salaries, and auditing pay by gender, you can build a development team that is both competitive and equitable.
