7 Hidden Costs in UK Security Guarding Contracts: Procurement Audit & Checklist
Direct Answer: Hidden Guarding Surcharges (Procurement Audit Summary)
Many UK security guarding contracts that initially appear cheap (£15–£17/hour) conceal significant contractual surcharges that inflate the final invoice by 25% to 45%. The 7 most common hidden costs include: 1) Bank Holiday premiums (charged at 1.5× to 2.0× rates); 2) Short-notice deployment penalties (£5–£10/hr uplift); 3) Relief cover and sickness billing; 4) Lone worker app and communications equipment rental (£25–£60/month); 5) Uniform and PPE recharging; 6) Minimum callout duration clauses (e.g. 8-hour billing for a 2-hour alarm check); and 7) Uncapped statutory wage pass-through escalators.
- Bank Holiday Surcharges: 1.5× to 2.0× standard rate unless fixed in contract
- Short-Notice Mobilisation Fees: £5.00 – £10.00 / hour penalty uplift
- Mandatory Tech & Lone Worker Fees: £25.00 – £60.00+ monthly fee per guard
- Minimum Shift Durations: Contracts enforcing 8 or 12 hours minimum billing
Bank Holiday & Weekend Surcharges: The 1.5× to 2.0× Trap
The single most common billing shock experienced by commercial facilities managers occurs on the first invoice following a UK Bank Holiday. Standard tender submissions often present an attractive baseline rate of £19.00/hour, while burying a clause in small print stating that all official Bank Holidays will be billed at double time (2.0×) or time-and-a-half (1.5×).
Across the 8 standard UK bank holidays (plus Christmas Eve, Boxing Day, and New Year's Eve), an unagreed 2.0× premium on a 24/7 site adds over £3,800 to £7,500 in unexpected annual billing. Conscientious contractors explicitly declare all holiday rate structures upfront or offer flat, all-inclusive blended annual hourly rates.
Short-Notice Mobilisation & Emergency Deployment Uplifts
When an unexpected security incident occurs—such as perimeter damage from storm conditions, an attempted break-in, or sudden intruder threats—businesses require emergency on-site officer attendance.
Disreputable suppliers exploit operational urgency by applying "emergency response uplifts" of £5.00 to £10.00 per hour on top of standard rates, alongside arbitrary "mobilisation management fees" of £150 to £350 per incident. A professional service agreement establishes a transparent emergency callout rate card with predetermined response windows.
The 7 Hidden Security Costs: Contract Trap vs Transparent Procurement Standard

| Hidden Cost Category | Typical Industry Trap / Surcharge | Annual Financial Impact | Eagle Security Protection Standard |
|---|---|---|---|
| Bank Holiday Premiums | Billed at 1.5× or 2.0× without clear pre-agreement | +£3,500 to £7,500 / year | Agreed transparent holiday schedule; flat options available |

| Tech & Lone-Worker Apps | £30–£60/month rental fee for patrol wands & apps | +£360 to £720 / guard / yr | Fully included within standard hourly rate; zero tech fees |
| Minimum Shift Durations | 8–12 hour billing enforced for 2-hour alarm checks | Up to 400% inflated callout | Clear transparent callout terms stated upfront in contract |
| Uniform & PPE Recharging | Separate invoice line items for hi-vis and boots | +£150 to £350 per operative | All branded uniforms & PPE fully supplied by ESP |
| Travel & Mileage Levies | Excess mileage billed if officer commutes >10 miles | +£15 to £40 per shift | All regional travel costs fully consolidated in rate |
| Uncapped Wage Escalators | Arbitrary annual price increases of 8% to 12% | Compounded budget creep | Documented indexation tied strictly to statutory wage changes |
Equipment, Uniform & Lone-Worker Protection Technology Fees
Ensuring officer safety and accountability is a statutory duty, not an optional luxury. However, many suppliers charge clients an additional line item for basic guard tour software, digital NFC check-in tags, radio communication sets, and lone-worker emergency alarms:
- Charging £25.00 to £60.00 per month per officer for "patrol tracking app licenses".
- Billing £120.00 per season for company uniforms, high-visibility outerwear, and safety footwear.
- Charging £45.00 for on-site guard logbooks and incident register stationery.
At Eagle Security Protection, all digital GPS tracking, control room check-in systems, and seasonal branded uniforms are considered fundamental operational tools and are 100% included in our agreed charge rate.
Statutory Wage Escalation Clauses: Indexation Realities
The National Living Wage increases annually on 1 April (for workers aged 21 and over, the statutory rate is £12.71/hour, effective 1 April 2026 as published on GOV.UK).
A compliant multi-year commercial contract must account for statutory wage adjustments. However, unprincipled contractors use these statutory increases to disguise arbitrary percentage hikes across their entire margin. A robust procurement contract should specify that rate adjustments reflect only the exact statutory increase in labor on-costs, preventing unconstrained budget inflation.
Due Diligence: Verifying BS 7858 Screening & COP119 Labour Supply
Beyond hidden financial line items, the most dangerous hidden cost is legal and regulatory liability resulting from unvetted staff or non-compliant subcontracting:
- BS 7858 Vetting: Without documented 5-year screening, insurers routinely reject commercial theft claims.
- COP119 Compliance: If your security contractor uses third-party labour providers, ensure they adhere to COP119 Labour Provision Rules to eliminate modern slavery and tax compliance risks.

Frequently Asked Questions: Security Contract Hidden Costs
What are the most common hidden costs in security guarding contracts?
The 7 most frequent hidden charges include unagreed Bank Holiday multipliers (1.5×–2.0×), short-notice emergency callout penalties (£5–£10/hr), communications and lone-worker equipment rental fees, minimum shift billing clauses, uniform recharging, travel allowances, and uncapped statutory wage pass-through escalators.
How much do security companies charge for Bank Holidays?
Unless fixed as flat all-inclusive rates in the primary contract, UK security suppliers typically bill Bank Holidays at time-and-a-half (1.5×) or double-time (2.0×). Across 8 official UK bank holidays, this can add £3,500 to £7,500 annually to a 24/7 contract.
Are lone-worker protection apps and patrol tracking included in hourly rates?
With transparent, ethical contractors like Eagle Security Protection, all digital GPS tracking, patrol confirmation tags, and lone-worker welfare monitoring are fully included. Lower-tier suppliers often add separate monthly technology fees of £30 to £60 per officer.
How do annual statutory wage increases affect long-term contracts?
Professional security agreements incorporate documented indexation clauses linking annual fee adjustments directly to published statutory National Living Wage changes, preventing arbitrary supplier price escalations.
