Why Choose Double Check
Reliable Service Comes From Familiar People
Security, cleaning and facilities management work better when the people on site know your building, your standards and the people they are protecting.
The same team, week after week
Low staff turnover means the officers and cleaners who learn your site tend to stay on it. You are not re-briefing a stranger every shift.
One contact, not a call centre
You get a named account manager and a 24 hour control centre in London staffed by real people. Log an issue day or night and someone who knows your site picks it up.
Accredited and independently audited
Officers are SIA licensed, and the company holds SIA Approved Contractor status, ISO 9001 and SafeContractor approval. These are checked by outside bodies, not claimed by us.
Cover that holds when people are off
Sickness, holidays and last-minute changes do not leave gaps. We plan relief cover so your site stays protected and clean without you chasing it.
Trusted on demanding sites
Our teams work on premium retail, hospitality and corporate sites across London. High-footfall, high-value places are the norm for us, not the exception.

Can one company handle security, cleaning and facilities management?
Yes. You can take security on its own, or add cleaning and facilities management under one contract. One account manager runs all three, with one point of contact and one set of reports.
Are your security officers SIA licensed?
Yes. Every guarding officer holds a valid SIA licence. The company is also an SIA Approved Contractor for door supervision and security guarding, and officers are trained for your specific site.
Where do you cover?
Our base is London and we work across the whole UK. That includes the South East, the North West, the Midlands, Wales, the North of England, Scotland and Northern Ireland, with national cover for multi-site contracts.
How quickly can you start?
We begin with a free assessment, usually within a few days. Once the plan is agreed we mobilise quickly, and we hold relief cover for sickness, holidays and last-minute needs.
How is pricing worked out?
Pricing depends on your site, the services you need, the hours involved and how often. You get a clear, no-obligation quote after a short assessment, so you see the full price before you decide.
