United Kingdom, in US dollars per hour, at each seniority level. Full-stack developer.

United Kingdom rates by seniority
Full-stack developer, the reference role, at every level. Seniority multiplies the band off the US Bureau of Labor Statistics wage distribution, so this range carries the width of that distribution rather than a locally observed spread.
| Level | Hourly rate | Monthly at 160 hrs |
|---|---|---|
| Junior 1-3 yrs | $42-$64 | $6,720-$10,240 |
| Mid-level 3-6 yrs | $53-$84 | $8,480-$13,440 |
| Senior 7-10 yrs | $68-$106 | $10,880-$16,960 |
| Staff / Principal 10+ yrs | $87-$132 | $13,920-$21,120 |
United Kingdom rates by city
Mid-level full-stack, modelled from the Numbeo cost-of-living index against London, Sep, 2026. Only cities with a published index appear here.
| City | Cost of living | vs London | Hourly rate | Basis |
|---|---|---|---|---|
| London The largest engineering market in Europe and its financial technology centre. Rates on this page are anchored here. | 89.7 | 1.000x | $53-$84 | modelled |
| Edinburgh A strong financial services and data engineering centre with a cost base well below London. | 75.1 | 0.837x | $44-$70 | modelled |
| Manchester The lowest cost base of the three and the largest general product bench outside the capital. | 69.9 | 0.779x | $41-$65 | modelled |
Why the city column barely moves. The widest cost-of-living gap between these cities is 28%, and the modelled rates differ by less again. A freelancer billing an international client prices against that market, not against local rent, so city is the weakest lever on this page. Treat the column as a tiebreaker between two otherwise equal candidates and nothing more. Every figure in this table is modelled from a consumer price index rather than measured from observed rates, which is why it carries a different badge from every other table here.
Hiring Costs by Platforms and Marketplaces
Buyer fees as each channel publishes them, read on 27 August 2026. Hourly rates are global market ranges, not United Kingdom rates.

| Upwork | 3% to 10%, plus $0.99 to $14.99 per contract | $25 to $150 an hour |
| Fiverr | 5.5%, plus $3.50 under $200 | $25 to $100 an hour |
| Toptal | Not published | $70 to $200 an hour |
| Arc.dev | 0% hourly, 20% of first-year salary permanent | $61 to $100 an hour |
| Agency or dev shop | 0%, margin sits inside the rate | $165 to $275 an hour |
| Recruiter, permanent | 15% to 25% of first-year salary | $20,500 to $34,500 per placement |
| Second Talent | 0% | $3,000 to $6,000 a month |
What really impacts the cost?
In United Kingdom seniority moves the rate more than any other lever, and the role premium is measurable against a published baseline.

What moves the rate in the United Kingdom
The United Kingdom is the closest large market to United States rates anywhere, and the market most often compared against Asia by European and American buyers alike. A mid-level developer works out at $53 to $84 an hour on published compensation data. This is a benchmark page rather than a sourcing market for us.
The deepest financial services and fintech engineering bench in Europe, concentrated in London, with genuine research and machine learning supply around Cambridge and a large general product bench in Manchester and Edinburgh. Native English across the whole band, which is the practical reason buyers pay the premium over Eastern Europe.
Pushes the rate up
- Financial services and regulated fintech, where London competes with banking budgets directly.
- Research and machine learning work, where the Cambridge and London pipeline prices against the United States rather than against Europe.
Pulls the rate down
- Hiring outside London, where the cost base is up to 22% lower, the widest internal gap of any market on this site.
- General web and application work, where the regional benches are deep.

How the United Kingdom figures are built
Derived, not observed. Stack Overflow 2025 publishes a UK full-stack median by name at 0.62x the United States figure, the highest ratio of any market on this site except Australia and the United States, and that ratio is applied to the same band the role pages use. We do not place engineers in the United Kingdom. We place engineers across nine Asian markets and the United Kingdom is not one of them, so this page is a benchmark rather than an offer.
Because the figures are derived, this range carries only the width of the underlying band, which is utilisation uncertainty of about 1.6 times. The Asian markets on this site carry rates observed at each seniority level, and their real junior to senior spread is closer to 2.3 times. A narrower range here is an artefact of the method rather than a tighter market, and the two are not directly comparable on width.
Every role on this page scales off the same band by the difference between its band and the full-stack band, which is why a machine learning engineer prices above a PHP developer here by the same proportion as anywhere else on this site.
Freelancer or employee?
The rates above are contractor rates: you pay for hours worked and nothing else. An employee costs a salary plus statutory employer contributions, and the comparison is not the one most people assume, because a freelancer at $30 an hour working full time is not cheaper than a $30-an-hour salaried equivalent once you account for the hours you do not buy.
If you are weighing a permanent hire in the United Kingdom instead, the salary rate cards price employment by country and role, with local currency bands and employer costs.
Questions buyers ask
How much does it cost to hire a freelance developer in United Kingdom?
A mid-level full-stack developer in United Kingdom bills $53 to $84 an hour, which is $8,480 to $13,440 a month at 160 billable hours. Junior rates run $42 to $64 and senior rates $68 to $106. These are rates we quote and place at in United Kingdom rather than a United States figure scaled by a compensation ratio, because the gap between junior and senior here is roughly twice what United States wage data predicts.
Which roles are cheapest and most expensive to hire in United Kingdom?
Of the ten roles on this page, PHP Developer is the cheapest at $38 to $62 an hour and Machine Learning Engineer the dearest at $74 to $115, both mid-level. The spread across roles inside one market is about 3.0x, which is wider than the gap between United Kingdom and most other markets for the same role. The skill matters more than the map.
Which platform is cheapest for hiring full-stack developers?
On fees, Arc charges nothing on hourly work and Upwork takes 3% to 10%, the lowest of the channels that publish anything; Toptal publishes none. On rates, Upwork spans $25 to $150 an hour and Fiverr $25 to $100, against $70 to $200 on a vetted network. The channel is the smallest lever you have: fees span 0% to 25%, while on this page geography moves the same hour about 4.3x and seniority about 2.6x.
How much cheaper is the United Kingdom than the United States?
Not much, and less than most buyers expect. Published medians put the UK at 0.62 times the United States figure, so a mid-level developer works out at $53 to $84 an hour against $85 to $135. That is the smallest gap of any market on this site except Australia. Teams hire here for native English, timezone overlap with both coasts of Europe and contracting simplicity, not for rate.
Is it worth hiring outside London?
It is the widest internal saving on this site. Manchester carries a cost base about 22% below London with the largest general product bench outside the capital, and Edinburgh sits between the two with strong financial services and data supply. For remote contract work the difference to a quote is smaller than the cost-of-living gap implies, because a freelancer prices against the market rather than local rent.

Comparing the United Kingdom against Asia?
These are published market rates, not an offer: we place pre-vetted engineers across nine Asian markets and the United Kingdom is not one of them. This page exists so you can benchmark against it. If you are hiring permanently instead, the salary rate cards price employment by country and role.
