How do you work as an electrician in the UK nuclear industry?

Where the nuclear electrical work is

There are two main kinds of nuclear work. One is new build. Hinkley Point C in Somerset is a 3.2 GW station under construction, and a government blog post from May 2024, written after an April 2024 site visit, put 10,500 staff on site. Sizewell C in Suffolk is next. The government expects it to employ 10,000 people at peak construction and to support 1,500 apprenticeships.

The other kind is operating and decommissioning sites. Sellafield in Cumbria is the largest. Sellafield Ltd describes its job as a century-long clean-up of Europe's largest nuclear facility. It takes on several hundred apprentices a year, and electrical is one of the disciplines. Most new-build electricians work for contractors. On decommissioning sites, many electricians are employed by the site company itself.

Getting on a new-build job as a qualified electrician

Look at a real Hinkley Point C advert from NG Bailey, which is one of the project's MEH Alliance partners. It was open to electricians, approved electricians and technicians. It asked for a recognised industry apprenticeship, NVQ Level 3 as a minimum, a recognised health and safety assessment certificate, a current SJIB or JIB ECS card and at least two years in an engineering construction environment.

If you want a supervisory role, you also need SMSTS, SSSTS or an equivalent. The work covered putting in containment and supports, glanding and terminating power and instrumentation cables, and testing and commissioning. If you have only done housing or small commercial jobs, spend time on larger industrial or engineering construction sites first.

Security vetting

Every nuclear job starts with a check. National security vetting has five levels: Accreditation Check, Counter Terrorist Check (CTC), Level 1B, Security Check (SC) and Developed Vetting (DV). CTC and above also require the Baseline Personnel Security Standard (BPSS) check. The employer decides which level a role needs.

Nuclear Waste Services is one example. It runs BPSS checks on everyone it recruits and adds CTC, SC or DV depending on the risk of the role, to meet government and Office for Nuclear Regulation (ONR) requirements. Some roles also have residency requirements, and these are written into recruitment. Expect your history to be checked before you start, and keep your records tidy.

How the work differs from ordinary sites

On paper the trade skills are the same. The difference is the discipline. Contractors expect work to be right first time, and they hold teams to project milestones. Shift patterns change as the workforce grows. The Hinkley advert offered a 38-hour, four-day basic week with overtime every second weekend, and warned that shifts would change. Shift working attracted extra payments.

Long projects also bring different terms. The same advert offered a matched 5% pension, 25 days' leave, an accommodation allowance, travel, and annual pay rises linked to RPI. Many people on these jobs work away from home, so take the allowances into account when you compare offers.

Pay

GBP a year, before tax. The percentile rows are ONS Annual Survey of Hours and Earnings, April 2026 (provisional), adjusted to the current year with a wage index. The regional rows are modelled estimates. The JIB rows are the official JIB National Standard Rates from 5 January 2026, worked out at 37.5 hours a week for 52 weeks. The Hinkley rows come from employer adverts and leave out shift pay and overtime, which add a lot to real earnings. Refer to the Electricians salary guide for figures from live adverts.
