Most London Staffing Agencies Will Let You Down.
Let's face it. Hiring staff for events on London shouldn't feel like a gamble. But if you've worked with traditional agencies, this probably sounds familiar:
Staff that cancel or ghost the day of the event
Low-quality or untrained staff who don't represent your brand
Poor communication from the agency (or none at all)
Zero accountability when things go wrong
Sounds familiar? You're not alone. These are the exact problems we built ASG to solve.
New Model. Real Accountability.
At ASG, we've rebuilt the staffing model from the ground up to give you:
A vetted team of trained professionals who want to work
Clear communication from booking to briefing to breakdown
Real-time updates & backup plans if things change
A guarantee that we'll show up and do the job right
The On-Time, On-Brand, Or On-Us Guarantee
Staffing your London event should never feel like a gamble. That's why we created the On-Time, On-Brand, Or On-Us Guarantee, the boldest promise on the business.
When you work with ASG, you're covered from start to showtime:
On-Time - If a staff member doesn't show up when promised, we'll replace them immediately or refund you.
On-Brand - All staff are pre-briefed and hand-selected to match your tone, values, and event type.
Or On-Us - If a staff member doesn't show up or doesn't meet expectations, we'll cover your next staffing needs, up to the same value - completely on us.
We don't just talk about reliability. We guarantee it.
