What this is

A specialist index of UK civil engineering jobs, with the pay attached

civilengineeringjobs.co.uk lists live civil engineering jobs across the United Kingdom and, next to them, what each civil engineering role is being advertised at right now — nationally, sector by sector, and city by city.

It is built for the whole of the market rather than one corner of it — highways, rail, water & environment, energy & utilities, buildings and the rest. Many of those adverts carry a plain job title, such as “Civil Engineer”, and say which market they are in only through the employer and the advert itself, which is why the sector is worked out separately from the role.

It covers 21 civil engineering roles, from civil engineer and structural engineer through site engineer, highways engineer, geotechnical engineer, quantity surveyor and civil engineering technician, split by seniority where the advert’s title says so, and mapped to roughly 67 UK towns and cities plus remote.

Each advert is also placed in one of 9 sectors — Highways & Roads, Rail, Water & Environment, Energy & Utilities, Buildings & Development, Aviation, Ports & Maritime, Flood & Coastal and Public Sector — from its title, its employer and our job partner’s category, and only then from specific phrases in the description. The employer’s market comes before the job’s function. An advert that does not say which market it is in gets no sector at all, because a wrong one would put the job, and its pay, in the wrong comparison.

It is narrow deliberately. A site that answers “what does a civil engineer earn in Manchester” precisely, with the sample size shown, is more use than one that tries to answer every question about every job in the country.

Where the numbers come from

How the advertised-pay figures are worked out

Every pay figure on this site is computed from the salary fields of live job adverts. There is no survey, no panel and no model.

  1. Read what the advert states. An advert with no figure — “competitive”, “negotiable”, “depending on experience” — contributes nothing. It is counted in the total number of adverts and excluded from the pay statistics.
  2. Normalise to a year. A day rate is multiplied by 230 working days; an hourly rate by 7.5 hours a day and then by the same 230 days. Where an advert gives a range, the midpoint is used. Where the unit is unclear, or the figure is implausible for its unit, the advert is left out rather than guessed at.
  3. Summarise. For each role, and each role in each city, each sector, and each role in each sector, we record how many live adverts there are, how many of them state pay, and the 25th percentile, median, 75th percentile, minimum and maximum of those that do.
  4. Snapshot daily and keep it. Each day’s figures are written as a new record and never overwritten, which is what makes a month-on-month trend real rather than recomputed.

The honest caveats

What these numbers are not

  • They are advertised salaries, not paid salaries. They are what employers and recruiters put in adverts. What someone ends up on after negotiation is a different number, and we do not have it.
  • They are a sample of live adverts, not the labour market. Only adverts that reach our job partner’s feed and state a figure are in them.
  • Below 5 adverts stating pay we publish no figure. Instead the page says how many adverts there actually are, shows the national figure for comparison, and asks search engines not to index it — so we never rank for a number we cannot stand behind.
  • We never interpolate. A missing number is shown as missing. Nothing on this site is filled in from a neighbouring city or a similar role.
  • We do not set pay. No figure here is offered, guaranteed or negotiated by us, and nothing on this site is financial or career advice.

Counts

What “1,214 jobs” means

Every count on the site is a count of live adverts matching exactly what the page lists — the same filters that produced the rows underneath it. Closed adverts are not counted. A search result’s headline is the number of adverts in that result, not the number in some broader set.

Citing a figure

If you are quoting one of these numbers

Please quote the sample size and the date with it, because both are on the page for that reason. “The median advertised salary for a civil engineer in Leeds was £X, from N live adverts stating pay, as at DATE” is a claim that can be checked. “The average civil engineer salary is £X” is not, and it is not what this site says.

Corrections

Something wrong on a page

If an advert is misfiled under the wrong role, sector or city, or a figure looks wrong, tell us and we will look at it. The privacy policy names the controller and gives the contact address; the terms set out what this site does and does not do.
