Manned Guarding Companies in Cardiff: 93 Active Firms (2026)
Manned guarding companies in Cardiff provide staffed security, site patrol and access-control services across the city and surrounding metropolitan area.
Buying centres cluster around facilities management, estates, operations and procurement, with buyers usually judging suppliers on cover, supervision and incident handling rather than on software features. The Cardiff customer base is likely to be mixed: commercial premises and logistics sites need regular rosters, construction projects need gatehouse and perimeter cover, while education, event and public-sector buyers tend to buy through more formal contract processes. Engagements usually look like recurring contracts with rota cover, relief staffing, shift scheduling, supervisory visits and service review, not ad hoc advisory projects.

Cardiff has 93 actively trading manned guarding firms, making the market a local contractor base rather than a national facilities-outsourcing universe. Reported employment totals 1,328 people, underlining that the footprint sits in officers, supervisors and schedulers rather than intellectual property or stock. The practical market context is therefore capacity: which firms can staff recurring shifts, provide relief cover, keep training evidence current and absorb short-notice changes from commercial, construction, logistics, education and public-sector clients.
Security licensing, vetting and labour compliance shape procurement more than formal product regulation. Buyers in public-sector, education, logistics and construction settings tend to ask for evidence of right-to-work checks, training, supervision, incident escalation and insurance before awarding recurring contracts. Guarding also exposes contractors to wage-cost pressure, absence cover and worker-safety obligations, so margins can be sensitive to roster design and relief staffing. For event and front-of-house work, reputational risk sits close to the buyer because guards interact directly with visitors, tenants and site staff.
The cohort appears likely to remain service-led, with competition turning on staffing reliability, supervisor quality and contract administration rather than proprietary technology. Many operators will tend to stay local because rota density and travel time matter in guarding economics. Scale is still possible, but it usually requires disciplined recruitment, back-office scheduling and the ability to pass buyer audits without adding too much overhead. Consolidation may appeal where owners want succession options, although labour availability and procurement scrutiny are likely to keep growth uneven.
What’s in the file
One row per company, 50+ columns — everything below plus each company’s verified directors, from Companies House filings.
Company data
Verified directors — included
Active director count is the full Companies House board, so it can be higher than the number of names listed — we leave out nominee and formation-agent directors, who aren’t worth contacting. It’s blank for the small number of companies whose officers we haven’t fetched yet.
You’re charged per business, not per row. Where a business trades through several registered companies you get every one, and the Group Primary column marks one row per business — filter to those and the count matches your invoice. Rows sharing a website are not automatically one business: franchises and multi-site operators each count separately, and where names don’t prove a relationship we count them apart rather than guess.

Key facts
About 3% of the trading cohort reports turnover above £5M (3 of 93 firms) — the rest sits below that revenue band.
36% of the cohort was incorporated since 2022 (34 firms), so a sizeable share is in its first few filing cycles.
Buyer selection tends to centre on shift coverage, vetting processes, response times and local labour availability.
Services commonly cover premises, events, construction sites and workplaces across Cardiff and the surrounding metropolitan area.
Contracts span static guarding, mobile patrol, access-control and facilities-adjacent work rather than one uniform service model.
The category sits close to facilities management and risk operations, with delivery shaped by staffing and site coverage rather than software-led security.

How Cardiff Manned Guarding companies work and how to sell to them
What they do
Cardiff manned guarding providers earn mainly from contracted labour, invoiced by the hour, shift, site or monthly service schedule. Gross margin sits in the spread between charge-out rates and officer wages, with extra revenue from mobile patrols, keyholding, alarm response, concierge cover, lock-up duties, event staffing and out-of-hours supervision. Pricing tends to reflect licence requirements, unsocial hours, travel time, relief cover, uniform, insurance and supervisor visits. The service is physical and operational rather than product-led: buyers are paying for attendance, accountability, incident logs and escalation discipline, usually under renewable contracts with break clauses and service-level reviews.
Who they sell to
Customers are usually facilities managers, estates teams, operations directors, site managers, procurement leads and finance approvers. Commercial landlords and logistics operators may buy directly from a shortlist, while education, public-sector and event buyers tend to use tenders, approved supplier lists or framework-style procurement. Sales cycles can be brief for a single construction gatehouse or temporary event, but longer where vetting, insurance, safeguarding, union considerations and site audits are involved. Contract values vary by rota pattern and risk profile, so proposals usually need to translate headcount, hours, supervision and escalation arrangements into a clear monthly cost.
What they buy
Most guarding firms tend to spend on workforce scheduling, time and attendance, payroll, HR, compliance training, vetting administration, incident reporting, lone-worker safety, fleet and mobile patrol management. They also buy uniforms, radios, body-worn cameras, access-control hardware, insurance, legal advice, accounting support and recruitment services. Larger operators may need CRM, bid-management, contract-management and management-information tools so supervisors can evidence service delivery across several sites. Back-office suppliers should expect practical buying criteria: whether the product reduces missed shifts, shortens payroll work, improves audit evidence or helps managers price tenders without losing margin.
Why and how to sell to them
Manned guarding operators tend to evaluate suppliers when a new contract stretches rota capacity, a supervisor leaves, wage costs move, a buyer audit is approaching or incident reporting starts to look inconsistent across sites. Newly incorporated Cardiff operators may be more open to outsourced finance, HR, recruitment and compliance support because the founder often still manages sales, scheduling and customer calls. Outbound messages are usually more credible when they refer to margin leakage, officer retention, right-to-work evidence, invoice accuracy or tender readiness, rather than generic efficiency claims. Case-led selling should use buyer types and operating pressures, not named customers.
How this list is built
Data sources
This list is built from UK Companies House filings, XBRL accounts data, and semantic analysis of each company's public website. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.
Classification
Rather than relying solely on SIC codes, Firmbase classifies each company semantically: the company's website is crawled, an AI model reads what the company actually sells, and the company is placed into the relevant industry and subsectors. SIC codes are used as one signal but not the only one. This means a company that registered under a generic SIC code but pivoted into (for example) fintech is correctly identified as fintech, not as its original SIC category.
Freshness
The underlying company data is refreshed from Companies House continuously; filings appear in the list within days of submission. The curated list ordering is regenerated when the underlying data moves meaningfully (company count changes by more than 5%, a new company enters the top-ranked segment, or the filed-revenue numbers for the top firms change). You can see the last-updated timestamp near the top of the page.
