The published rates vs. reality
Advertised hourly rates for Construction Site Security roles cluster around £12–£14. In practice, take-home depends on overtime, unsocial-hours premiums and site-specific allowances. Read the assignment instructions before the pay slip.
Regional variation
London and the South East pay 10–20% more for the same duties, but rent and travel usually swallow the differential. Regional cities (Manchester, Leeds, Birmingham) often offer better real income than central London for identical shifts.
What actually moves the number
Sector: corporate, data centre and pharma clients pay materially more than generic guarding.
Vetting: BS7858, SC and DV vetting all unlock roles closed to unvetted staff.
Specialism: Perimeter checks and Plant theft awareness skills add meaningful uplift.
Getting a pay rise inside the same job
Track your hours, incidents and outcomes for six months. Request a meeting with a written case: reliability, incidents handled, training completed. Ask for a specific rate, not a percentage.
If the answer is no with no timeline, another employer with the same client will pay you more for the same site within 30 days.
Progression maths
Moving to Gate Supervisor typically adds £2–£4/hr. Multi-site Supervisor usually adds £5–£10k salaried. Progression pays; loyalty at the same static rate does not.
