Why your shift engineer roles aren't filling.

A shift vacancy that stays open does not stay empty for free. Someone else covers the rota, overtime climbs and the rest of the team tires. The cause often sits in the offer rather than the candidate market, so here is what the CBW Salary Survey 2026 shows and what we would check first.

Know what the shift premium really is

Our survey covers 54 FM positions. For electrical and mechanical engineers, days and shift compare like this:

• Electrician / Mechanical (Days): £45,000 minimum, £48,000 average, £50,000 maximum
• Electrician / Mechanical (Shift): £50,000 minimum, £52,000 average, £55,000 maximum

At the average, the difference is £4,000 a year, or about £77 a week before tax. That is the figure an engineer sets against nights, weekends and time away from home life. Expect them to do that sum before they reply.

Look too at where the bands meet. The top of the days range is the bottom of the shift range. An engineer already earning £50,000 on days gains nothing in salary from a shift role at £50,000, and takes on the pattern as well. A role pitched at that level is asking your strongest day engineers to move sideways.

Tell engineers what the job actually is

Engineers judge a shift role on the pattern as much as the pay. "Rotating shifts" and "shift allowance" tell them very little, and the good ones already in work have no need to ring and ask. A useful advert answers these questions up front:

• Pattern: days on and off, nights per rotation, and how much notice is given of changes
• Cover: whether nights are single-manned, and who is on call behind the engineer
• Pay: basic and shift allowance shown separately, plus how overtime and call-ins are paid
• Site: the type of building and what the engineer is responsible for out of hours

Check the spec against the salary

Shift engineers do need range. There are fewer people on site at 3am, and the engineer on duty has to find the fault and make the plant safe. That is a fair reason to set the bar high, but the bar has a market price. Compare the shift average of £52,000 with these survey averages:

• Chiller Engineer: £53,000
• M&E Lead Engineer: £55,000
• Combustion Engineer (Commercial): £55,000
• BMS Engineer: £60,000

If your shift spec asks for deep chiller, controls or combustion experience on top of a broad M&E background, you are competing with those salaries. Decide what is essential on day one and what you can train.

Show where the shift leads

Many engineers do not want to work nights indefinitely, so they will want to know what comes next. The survey shows a clear ladder above the shift engineer:

• M&E Shift Leader: £60,000 average
• M&E Shift Manager: £65,000 average

That is £8,000 and £13,000 above the shift engineer average. If your contract has a route like this, or a route onto days, put it in the advert and mention it at interview.

Widen the pool without lowering the standard

Several clients ask us specifically for ex-forces engineers. We place a large number of them, mainly from the Royal Navy and Royal Engineers. They are used to structured working and duty rotas, which makes a shift pattern less of a shock than it can be for someone coming from days.

Widening the pool does not mean relaxing the checks. We confirm tickets such as 18th Edition, F-Gas, NVQ Level 3 and L8 before anyone reaches your shortlist.

What this means if you're hiring

• Benchmark the role: if it sits at the shift minimum, expect a small pool
• Publish the pattern: put the rota, cover and allowance in the advert
• Trim the spec: separate the essentials from the things you can train
• Show the next step: tell engineers where the role can lead
• Protect the rota: use temporary cover while the permanent search runs

If a shift role has been open longer than it should, talk to us. Send us a vacancy (/submit-a-vacancy) or call 0203 583 3099, and we will tell you plainly how your offer compares. If you are an engineer weighing up a move, see our live roles (/job-results).
