What Affects Pay in UK Energy Jobs: Salaries, Day Rates and IR35

Why energy pay varies so much

Two people with the same job title in the energy sector can earn very different amounts. Pay depends on whether you are permanent or contract, onshore or offshore, on days or shifts, where you are based, which tickets you hold and who you work for.

This guide explains the main factors so you can compare offers properly. It deliberately avoids quoting typical figures, because rates change with the market and vary between employers. Use it to ask the right questions and to read adverts with a clearer eye.

Permanent salary versus contractor day rates

Permanent packages

A permanent salary is only part of the picture. When you compare permanent roles, look at the whole package:

• basic salary and how it is reviewed
• overtime rates and how much overtime is realistically available
• shift, standby and call-out allowances
• employer pension contributions, which vary a great deal between companies
• bonus schemes, company vehicle or car allowance
• holiday entitlement, sick pay, private healthcare and training budgets

Regulated network companies and large generators often offer structured pay grades and generous pensions, while smaller firms may pay a higher basic with fewer benefits.

Day rates

Contractors are usually paid a day rate or hourly rate. A day rate typically looks higher than the equivalent permanent salary, but it has to cover things an employer would otherwise provide: holiday, sick days, gaps between contracts, pension, training and ticket renewals, insurance and, for limited company contractors, accountancy costs.

Contract rates also move with demand. During major outages, construction peaks or shortages of particular skills, rates for experienced people tend to rise. When projects finish or are delayed, they can fall back.

Offshore rotations and allowances

Offshore work in oil and gas and offshore wind is usually organised in rotations, such as two weeks on and two off, two on and three off, or three on and three off. The rotation affects how many days you actually work each year, which matters when you compare a day rate with an annual salary.

Pay for offshore roles may include an offshore allowance on top of basic pay, payment for travel days, and different rates for standby or weather days when work cannot go ahead. In offshore wind, some technicians work from crew transfer vessels on day trips from port, while others live on service operation vessels for a full rotation, and pay arrangements can differ between the two.

Always check how travel time, mobilisation, training days and weather downtime are paid before accepting an offshore role.

Shift work and premiums

Power stations, control rooms, network fault teams and many operations roles run around the clock. Employers usually compensate with shift premiums, often a percentage of basic pay or a fixed allowance, and with higher rates for nights, weekends and bank holidays.

Many network and maintenance roles also include standby or on-call duties, paid as a standby allowance plus a call-out payment or overtime when you are called in. Ask how often you would be on the rota and how call-outs are paid, as this can make a noticeable difference to annual earnings.

Location

Where you work affects pay in several ways:

• Cost of living – roles in London and the South East often include a location allowance or higher basic pay.
• Local competition – areas with clusters of energy employers, such as Aberdeen and the North East of Scotland, Teesside or the Humber, can see stronger competition for skilled people.
• Remote sites – projects in the Highlands, on islands or at isolated sites may pay accommodation, subsistence or remote working allowances.
• Working away – construction and contract roles often include lodging or living away from home allowances, which may be paid separately from your rate.

Tickets, authorisations and experience

Certificates that are expensive to get, take time to earn or are in short supply tend to push pay up. Examples include high-voltage authorisation and senior authorised person status, CompEx for hazardous areas, offshore survival and GWO training, specialist welding coding, and security clearance for nuclear and defence work.

Chartered or incorporated engineer status, specialist software skills and a record on comparable projects also strengthen your position when you negotiate. Keeping tickets current matters: a lapsed certificate can stop you starting a contract at all.

Employer type and agreements

Pay structures differ between asset owners, contractors and consultancies. Some sectors use collective agreements that set rates and conditions for particular kinds of work. Examples include the JIB agreements in electrical contracting and the National Agreement for the Engineering Construction Industry, which applies on many major engineering construction sites. If a role falls under an agreement, ask for the relevant grade.

IR35 basics for contractors

If you work through your own limited company, the off-payroll working rules, often called IR35, affect how you are taxed. The aim of the rules is that someone who would be an employee if they were engaged directly pays broadly the same income tax and National Insurance as an employee. The government's off-payroll working guidance sets out the detail.

• Who decides – for public sector bodies and medium or large private sector clients, the client is generally responsible for deciding whether the rules apply. For small clients outside the public sector, your own company makes that decision.
• Status determination statement – where the client decides, it should give you a statement of its decision and the reasons for it. Clients must also have a process for you to disagree.
• Inside IR35 – if the rules apply, the organisation paying your company deducts income tax and employee National Insurance before paying you, much like an employee, although you do not gain employment rights.
• Outside IR35 – if they do not apply, your company is paid gross and you handle tax through your company in the usual way.
• Contract by contract – the rules are assessed for each engagement, so one role can be inside and the next outside.

HMRC's Check Employment Status for Tax tool can help with the assessment. If you work through an umbrella company, you are its employee and taxed through PAYE, so the off-payroll rules are unlikely to affect you in the same way. For your own situation, take advice from a qualified accountant.

Comparing offers

Before you accept, write down the total value of each offer, including allowances, pension, holiday and how much overtime is realistic. For contract roles, estimate how many days you will actually work in a year and subtract your own costs. Then weigh the non-financial factors: travel, time away, progression and job security.
