Frequently Asked Questions About Our Security Services
Answers to common questions about our security services in Greater London, Leeds, Sheffield, Liverpool, Birmingham and Manchester.
Which areas does GSS Securities cover?
We provide security services in Greater London, Leeds, Sheffield, Liverpool, Birmingham and Manchester. GSS is headquartered in Rainham, London, and Greater London is our core coverage area. In the other locations, availability is confirmed by enquiry, based on your site, risk level and staffing needs. Get in touch and tell us where your site is and what protection you need. We’ll confirm whether we can support your location and service before you take anything further.
What types of sites do you secure?
We support commercial and public-sector sites, including offices, retail environments, education, healthcare and construction sites. Every site has its own risks and routines, so we plan cover around your premises, operating hours and risk profile.
What security services can I get?
We don’t sell a fixed package. Instead, we recommend the right mix of guards, patrols and technology for your site, and nothing you don’t need. Please tell us what you need protected, and our team will recommend an approach.
What does SIA Approved Contractor mean?
The SIA Approved Contractor Scheme is a voluntary scheme in which security companies are independently assessed against set standards for how they operate and manage their staff. GSS is an SIA Approved Contractor, and you can check our status on the SIA website.
What is BS 7858 vetting?
BS 7858 is the British Standard for screening people who work in security. It involves checks into an individual’s identity, employment history and background, so you know who is on your premises.
How do you decide what level of security my site needs?
We start with your site: what you’re protecting, when it’s busiest and any concerns you have. From there, we recommend the level of cover, patrol approach and technology that fit your risk, so you only pay for what the site needs.
What information do I need to request a quote?
Your site location, the type of site and the hours you need covered. If you know how many officers you need, or what worries you, include that too. If you don’t have everything, our team can help assess your requirements.
How quickly can cover start?
It depends on your location, site and the service you need, so we confirm availability when you enquire. If your need is urgent, say so in your enquiry and give us the date you need cover to begin.
