K4 Group of Companies: integrated security and medical services from Hounslow

K4 Group of Companies is a UK-based multi-service provider headquartered in Hounslow, London. Founded by Arsalan Khan, the group has expanded from a single security company into a family of six specialised businesses, each dedicated to a specific area of expertise. Its activity spans security, medical, training, workforce, CCTV and digital services, and it serves clients nationwide across England, Scotland and Wales.

The group's stated model is to replace several separate vendors with a single point of contact. Instead of contracting manned guarding, event medical cover, CCTV monitoring and staff recruitment independently, clients deal with one group that coordinates those services together. K4 Group reports a workforce of over 1,000 trained professionals and states that it owns ACS-approved companies.

The six companies within the group

Each company concentrates on one field, while the group presents them as a combined offer:

• K4 Security Services — manned guarding, mobile patrols, event security, door supervision and key holding, delivered by licensed officers.
• Bridge Facilities Services — event security, mobile patrols, keyholding, property maintenance and facility management.
• K4 Medical Services — event medical cover, ambulance hire, first aid, patient transport and on-site paramedic services; the company describes itself as CQC-registered and NHS experienced.
• K4 Training Company — SIA licence courses, first aid training, fire safety, health and safety, and bespoke corporate training programmes, described as nationally accredited.
• K4 Workforce Services — temporary and permanent staffing across security, hospitality, events and construction, with recruitment and HR support.
• K4 CCTV Services — CCTV installation and maintenance, mobile CCTV towers for events and construction, and certified monitoring staff.

A further entity, K4 Global Pvt Ltd, covers control room operations, BPO services, web development, graphic design, digital marketing and content writing.

Sectors served

The group lists six main sectors: events and festivals, construction, retail, corporate, education and hospitality. It also mentions work in stadiums, healthcare and public sector environments. Examples given include event safety for festivals, retail store security officers, campus security in education, site security and access control in construction, office and event support for corporate clients, and guest safety for hotels. Security and medical teams can be deployed together under one contract, a combination the group highlights for events, festivals and large construction projects.

Accreditations and track record

K4 Group states that its companies hold ACS approval, ISO 9001, 14001 and 45001 certifications, CHAS, SafeContractor and ConstructionLine accreditation. It also cites industry awards, including OSPA and West London Business Awards recognition. Among its references, the group mentions deploying more than 500 officers for the Commonwealth Games and hosting VIP lounges at the Event Production Show. It reports that staff can typically be deployed within 24 to 48 hours, with larger projects planned further in advance.

Origins and community involvement

According to the group's account, Arsalan Khan began working at 18 as a steward in the stadium industry, later served in the police and spent over 11 years in the private security sector, rising into senior leadership and overseeing large-scale deployments at national events. The recurring problem he observed was the fragmentation of security, medical, CCTV and staffing across separate providers, which led to the creation of the group.

The company's news section, as published at the time of writing this profile, records sponsorship of The Mulberry Centre's 25th Anniversary Gala as headline sponsor, a third consecutive season as Richmond FC club partner for 2026/27, and a fourth consecutive appearance at the International Security Expo 2026.
