Data Centre Jobs UK: 7 Real Salaries and Top Employers 2026
Slough, just west of London, now runs on around a gigawatt of data centre capacity and supports more than 14,000 local jobs, according to a 2026 report from operator Kao Data.
That single town is the clearest signal of what is happening across the whole country.
Data centre jobs in the UK are growing fast, they pay well above most facilities and IT roles, and many of them do not need a university degree to start.
This guide covers the real salaries by role, where the jobs are concentrated, which employers are hiring, and how to get your first role in 2026.
One quick note before the numbers: UK listings appear under two spellings, “data centre jobs” and the American “data center jobs,” so search both when you look for openings.
Data Centre Jobs UK: What They Actually Pay
A data centre technician in the UK earns about £35,000 a year on average in 2026.
Cross-referenced figures put the national average at £35,173 (Glassdoor), £35,570 (Indeed), and £38,506 (ERI SalaryExpert), so the true middle sits close to £35,000 to £38,000.
Pay climbs sharply as you move up the technical ladder.
A data centre engineer commands a UK median of £47,500, with the top quartile reaching £65,000, based on advertised vacancies tracked by ITJobsWatch to January 2026.
The best-paid operational role is the critical facilities engineer, who keeps the power, cooling, and backup systems running.
ERI SalaryExpert puts the average critical facilities engineer salary in London at £84,120, with entry-level pay around £58,877 and senior engineers averaging £104,490.
Shift work adds more on top, because these sites run 24 hours a day, every day of the year.
A recent Slough shift technician advert listed pay up to £55,000 plus overtime, and continental shift patterns often carry allowances beyond the base figure.
Here is how the main roles compare across the UK in 2026.
| Role | Typical UK salary (2026) | Source |
|---|---|---|
| Data centre technician | £33,000 – £38,500 | Glassdoor, Indeed, ERI SalaryExpert |
| Data centre technician (London) | £39,000 – £44,000 | Glassdoor, Indeed |
| Data centre engineer | £47,500 median | ITJobsWatch |
| Shift technician (Slough) | up to £55,000 + overtime | Jobsite advert |
| Critical facilities engineer (London) | £58,877 – £104,490 | ERI SalaryExpert |
London pay runs roughly 12% above the national average for technicians, per Glassdoor, which partly reflects the higher cost of living in the capital.

Where the Data Centre Jobs Are: London, Slough and Beyond
London is the largest data centre market in Europe, and that is where most UK jobs sit.
Mordor Intelligence estimated the London market at 2.77 GW of installed capacity in 2026, on track to reach 5.16 GW by 2031 at a compound growth rate of 13.21%.
Slough is the beating heart of it.
The town hosts more than 30 operational data centres and over 675 megawatts of hyperscale capacity, making it the single largest data centre cluster in Europe, per Kao Data.
Power limits are now pushing new sites outward.
CBRE’s UK Data Centres Outlook 2026 reports that grid constraints in Slough and the Docklands are steering fresh development into North London, Oxfordshire, Hertfordshire, and Essex, with a key Slough substation upgrade not expected before 2029.
The government is spreading the map wider still.
Its AI Opportunities Action Plan created a set of AI Growth Zones in places like Culham in Oxfordshire, Teesside, Newcastle, and both North and South Wales, opening job markets well beyond the M25.
Wales already holds a heavyweight: the Vantage campus in Newport (formerly Next Generation Data) is one of the largest single data centre sites in the country.
Manchester and Birmingham round out the growing regional markets, drawing cloud and enterprise demand outside the capital.
Who’s Hiring: The Biggest UK Data Centre Employers
The UK hosts roughly 500 data centres run by more than 200 providers, according to industry database Baxtel.
That gives job seekers a deep bench of employers to target directly.
VIRTUS Data Centres leads the UK in total colocation capacity, ahead of Equinix and Digital Realty, per market tracker Brightlio.
The largest operators by portfolio also include Vantage Data Centers, Ark Data Centres, Telehouse, Global Switch, and Kao Data.
The hyperscalers hire heavily too.
Amazon Web Services, Google, and Microsoft all run and staff their own UK facilities, and Indeed salary listings show Microsoft and CBRE among the active recruiters for London technician roles in 2026.
Equinix is a strong first target for new entrants.
The company runs its Slough and London campuses (LD4, LD5, LD6, LD10) and posts openings for critical facility engineers, customer operations technicians, and apprentices on its UK careers page.
Specialist recruiters fill many of these seats, so it pays to register with data centre and critical-environment agencies alongside applying directly.
How to Break Into UK Data Centre Jobs With No Experience
You do not need a degree to start, and the fastest route in is an apprenticeship.
An apprenticeship pays you a wage while you train on-site toward a recognised qualification, usually over 18 to 48 months.
Equinix is expanding its early-career pipeline in 2026, naming the UK among the first markets in a newly centralised global apprenticeship, internship, and operations training structure with a refreshed curriculum.
Its new Learning Labs target people with electrical or electrotechnical backgrounds and cover practical skills across power systems, cooling, climate control, and safety.
Trades transfer well into this industry.
Electricians, HVAC engineers, mechanical fitters, and military technicians already hold much of the hands-on skill set operators need, which shortens the jump into a technician or shift role.
The credentials that lift pay are vendor and industry certifications, not academic degrees.
EPI’s Certified Data Centre Professional and Uptime Institute operations credentials are common asks in UK job specs, and both add weight to a CV for facilities roles.
Government money is flowing into the wider trades pipeline as well, with £600 million committed to create up to 60,000 more engineers, electricians, and skilled tradespeople by 2029.

The Skills Shortage Driving UK Data Centre Hiring
Demand for workers is outrunning supply, and that is good news for anyone entering the field.
More than half of data centre operators struggle to attract and retain qualified staff, according to Uptime Institute research cited by the World Economic Forum.
The UK has a specific demographic problem.
Around 19% of UK data centre professionals are over the age of 55 and heading toward retirement, while nearly a third have fewer than three years of experience, per recruitment firm NPS, leaving a thin layer of mid-career specialists.
Skills gaps show up most in the fast-growing technical areas.
A 2025 IDC info brief cited by Colt Data Centre Services found UK gaps in networking (40%), cybersecurity (44%), and data, AI, and automation (33%).
The workforce is also short on diversity, with women making up less than 10% of the sector, which operators and industry bodies are working to change through targeted hiring.
AI is pouring fuel on all of it.
CBRE notes that every large London campus is now being planned with AI in mind, driving higher power densities and, with them, demand for engineers who can run denser, more complex sites.
The takeaway for a job seeker is simple: the shortage means faster hiring, stronger pay growth, and real room to move up once you are in.
Is a UK Data Centre Job Worth It in 2026?
For most people weighing it up, yes.
The pay beats comparable facilities and IT support work, the entry routes are open to trades and career changers, and the demand curve points straight up for the rest of the decade.
Start by targeting an apprenticeship or technician opening at Equinix, VIRTUS, Vantage, or a facilities-management provider serving the Slough and London campuses.
Register with two or three specialist data centre recruiters at the same time, and search under both the “centre” and “center” spellings.
Line up a recognised certification such as the EPI CDCP once you are working, and use the shift-pattern and overtime uplifts to push your total pay well past the base figure.
The runway here runs for years, not months, so getting in now puts you ahead of the wave of AI-driven expansion still to come.
