The gender pay gap league: architectural and engineering activities; technical testing and analysis, 2025/26

88 architectural and engineering activities; technical testing and analysis employers reported for 2025/26. The median employer's gap: women's median hourly pay 18.1% lower than men's.

These are the employers' own figures, reported under the gender pay gap regulations (250+ employees must report). The gap compares MEDIAN hourly pay of men and women across the whole workforce — it is not a like-for-like pay comparison for the same job.

A positive gap means women's median pay is lower; a negative gap means men's is. "Closest to parity" ranks by distance from zero in either direction. National and sector medians are on the pay gap statistics page.
