Top 37 Security Companies UK 2021 | Ranked by Review Rating

Top 37 UK Security Companies

The experiences of other customers with a provider is key to making an educated decision about which company to move forward with. Whether you are running a strict procurement process and inviting tenders or if you are just calling round your local firms, you need to know what their customers and employees are saying. Rather than rank these companies based on their size, we have opted to rank them based on what their customers say about them.

Below we have ranked the top 37 UK Security Companies in order of either their Google Review stars or their Trustpilot Rating. We looked first for a Google Review and if one couldn't be found then we went to Trustpilot. All of the below companies operate in the regulated security industry, deploying staff to client sites.

37. Allied Universal


No. of Guards: 210


Trustpilot Stars: 1.6


Trustpilot Best Review: All negative comments


Trustpilot Worst Review: "The worst security company ever! Do not hire them. In 4 years I called 4 times on different safety matters. Either they didn't show up, showed up long after the threat was diffused or outright neglected the call and got hung up on by untrained personnel. Wouldn't trust them with any safety issue in the future. BEWARE"


Typical Comment: Generally positive, although with it being a larger company there is a long list of complaints from employees


36. Kingdom Services Group


No. of Guards: 2159


Google Review Stars: 2.3


Google Reviews Best: "Kingdom has been a business partner of ours for a great number of years and have always been an absolute pleasure to work with. They have fantastic attention to detail, and we feel that we are in safe, knowledgeable hands with them."


Google Reviews Worst: "Worst and least effective security company i have ever come across. Unable to perform simple tasks. Do not employ their services. Total waste of money."


Typical comment: Generally positive from customers although there are a few negative comments, from former employees it is generally negative with a few gibing a positive review of the company.



35. Cordant Security


No. of Guards: 3931


Google Review Stars: 2.3


Google Reviews Best: "Out of every Security company I have ever worked for. I can hands down say Cordant Security is the best. I've been with the company for a while and have progressed up the ranks. I've worked on the shop floor, recruitment, control room and now a manager. My hard work was recognised and rewarded. I feel as part of a family. The hierarchy within Cordant services as a whole has always been supportive to me and I've learned a lot from everyone I have worked with. I've always been paid on time or early. Mistakes are always swiftly rectified if there are ever any. You couldn't ask for a better company than Cordant Security. Throughout lockdown they've supported everyone to the best of their abilities, they try hard to accommodate everyone, there are no surprises with Cordant everyone is always upfront, honest and courteous.


Google Reviews Worst: "Went to my local Tesco yesterday and the store was very busy being a Friday night yet 2 security guards were not in post but I observed them laughing and joking smoking outside for a long time. It was a great time for opportunist thieves to walk out with a shopping trolley FULL of groceries??just saying".


Typical comment: Lots of disgruntled employees, with a few complaints from the general public which is to be expected with a company of this size.


34. Showsec


Google Review Stars: 2.5


Google Reviews Best: "Great place to work, highly professional. Would recommend to any SIA badge holders looking for a decent company to work for or anyone looking to hire event security.


Google Reviews Worst: "Having seen how your trained staff deal with a member of the public wearing a union jack wastecoat to a British boxing match is sickening. EVERY Showsec member of staff involved in that video needs to be sacked and charged with assault, they do not have a brain cell between them all. Every person should boycott ANY event that this company is contracted too. Seriously don't deserve one star. Thugs. Would you want this calibre of staff looking after your event? Avoid at all costs.


33. Corps Security


No. of Guards: 3092


Google Review Stars: 2.6


Google Reviews Best: No positive comments that we could find on Google reviews.


Google Reviews Worst: "I had applied for a vacancy advertised on job indeed for a fulltime security job leeds Carly Bedford had rung me up to inform me there will be a interview over facetime due to covid 19 we had agreed on a day and time. On the day I didn't receive a call from the person who was meant to take my interview. Later that day I rung corps security and asked to speak to carly Bedford and informed her no one had conducted my interview. She told me the manager had a Emergency to deal with I thought yeah cool fair enough so we arranged another day and time for a interview. NOBODY rung me again. I messaged carly bedford letting her know its happened second time to me and how it look unprofessional on they company part. But she never responded back. I seen 3 star ratings and still thought of giving them a try. But honestly dont waste your time look else were AVOID!!"


Typical Comment: All comments are negative

Google Reviews Best: "Worked very closely with the door staff during my time as a bar manager - all I can say is thanks to all of the guys and girls who kept my customers and staff safe excellent service."


Google Reviews Worst: "Wouldn't trust them to keep bubble wrap safe!

Booked them to attend and support my event. Travelled over an hour to meet with the person assessing my venue. They didn't show and when i called to find out why i was told the team was all hungover after watching the football so hadn't bothered. What a disgrace of a company."


Typical Comment: Lots of negative reviews from former staff and customers. There are a number of bright spots though


31. I.C.T.S.


No. of Guards: 3473


Google Review Stars: 3.1


Google Reviews Best: "Each time I go on holiday, I mean to write this review... finally, here it is... Although you may go unnoticed working behind the scenes, you are not unappreciated. I want to say a big THANK YOU to all the people at ICTS for keeping my family, friends and community safe as we travel, work, shop, holiday, study, heal and entertain ourselves - every single day. So, whether you are guarding, patrolling, installing, scanning, screening, analysing, protecting, reuniting, serving and whatever else you people do, please keep on doing it. You guys are the BEST."


Google Reviews Worst: "Worst company I have ever had to displeasure of dealing with. Still got on-going issues that have been open with them for over 1 year with no progress being made. Never reply to emails / questions, Don't even know the products their own company supports. Essentially given up on half of our support tickets. Want you fix products you pay them to fix. Engineers are untraining, unprofessional and lacking basic troubleshooting skills & knowledge. Do yourself a favour and give these a miss."


Typical Comment: Positive comments from the general public, negative comments from former employees


30. Carlisle Group


No. of Guards: 3000

Google Review Stars: 3.1


Google Reviews Best: "Great place with friendly staff".


Google Reviews Worst: "I had problems with their security guards coming to site on time or at all. I then have problems trying to get through to their help desk to find out where there guards are."


Typical Comment: Fair number of negative comments from customers especially compared with other companies on the list. Comments left by employees are mostly negative, but this is common for companies of this size.


29. Total Security Services



Google Reviews Stars: 3.1


Google Reviews Best: "I have worked in the UK security industry for more than 20 years, during this time I have been employed by companies large and small, many of these have been dubious in their credibility (often in spite of their best intent), whilst others have been too small to be effective. TSS however is different...without a doubt they are the most supportive, company in the marketplace right now; big enough to supply clients and staff with the resources to do the job, yet still retaining a family ethos. I have no hesitation in recommending them as an employer or a supplier...".


Google Reviews Worst: "Don't answer the phone. Some Guards that we have are more like a wet weekend. Relief guards don't arrive on time or not at all. Some don't understand us or we don't understand them due to language barriers"


Typical Comment: Typically negative from former employees from the comments left, very few comments from customers and therefore we struggled to find positive remarks from customers.


28. Lodge Security International


No. of Guards: 585


Google Review Stars: 3.4


Google Reviews Best: "Very professional service."


Google Reviews Worst: "Dreadful security guards provided especially the idiots in dundee primark with bad attitudes who pass remarks about shoppers play on their phones and don't seem interested in the work they do"


Typical Comment: Generally positive with only a couple of negatives from the public. Also a number of complaints from former employees.


27. STM Group (UK) Ltd


Guard Numbers: 1050


Google Review Stars: 3.4


Google Reviews Best: "Most of my career has been working on the side of the client therefore I have always been involved in the procurement and selection of high level security officers. All I ever wanted was a company who said what they meant and meant what they said but this was as rare as the Dodo! It was unattainable and sadly, I resigned myself to mediocrity until I found Paul Jacomb and his company STM. I will not labour on this point however I have to tell you that if they shake your hand on a promise or a deal. They will deliver!".


Google Reviews Worst: "Obviously this doesn't reflect all staff, but most are inadequate jacket fillers who barely know customer service. This one guy keeps trying to get free travel on a public transport service with his STM ID card and playing it like he doesn't know it's not valid for that travel. Regular guy that keeps coming and trying it on with the station staff, and he's rude about it too. Those that work in the National Rail station are thick as."


Typical comment: The usual complaints from would-be employees, as well as a number of complaints from the general public about the standard of service.


26. Churchill Security


No. of Guards: 200


Google Review Stars: 3.5


Google Reviews Best: "A Quick Thank you to Churchill Security Limited.

In this age not too, many people feel compelled to write a thank you letter to a company but the level of service, support and communication from Churchill has been second to none.
As you are aware, I found our company in a precarious situation with an immediate need for 24 hour security, never having been in this situation before I made calls to a few local security firms and was greeted with tiered, confusing pricing, contracts, the confusion got worse as I delved further.
I made a chance call to Churchill security and dealt with Elina Staimilere, I was immediately struck by her no-nonsense approach and subsequent guarantees as we discussed our needs further. That same evening our first security officer arrived, on time, fully briefed, well presented but most importantly capable of seeing through what was required.
Obviously being new to this type of industry there were many aspects I was unsure of, a call (four!) to Elina and all my questions were answered promptly, without confusion and clearly. My fears of Churchill over promising and under achieving were well and truly allayed.
Since that first evening of stress and worry I can now leave our offices in the evening without having to worry, every touch point from Churchill has led to this point and I can only thank you sincerely for taking the stress off my shoulders.
I have since met Luke Toker – National Operations Manager on a site visit to our premises and was once again impressed by a straight talking, knowledgeable member of the Churchill team re-enforcing my initial opinion.
I must say Elina is a deeply impressive ambassador for your company, she has been nothing other than ultra-efficient, informative and quick to respond to anything I’ve thrown her way (as well as impeccable grammar in her emails, a rarity!) Thank you, Elina.
Well done Churchill, keep up the good work, I’m certain you can do nothing but succeed with the business model and approach you have built."


Google Reviews Worst: "Their name mis-informs you from the start: they are nothing but 'LIMITED'.


This abomination of a company was supposed to be on guard through a filmmaking outing. They were to arrive at 5:30am, guard until 2pm, and then their day would be over.

This was, however, too challenging a task for the soiled toddlers running the company. Instead, they sent out two untrained men who were not qualified for the job. They then twiddled their thumbs while the office "called around" to find replacements for the next 7 hours. This was met with a grinding stop after they decided to claim that they have not received enough money for the men they could send out. So it seems as though the soiled children were maturing into semi-decent money-hungry sharks.


Overall, avoid this company at all costs! If you are in need of security you are better off praying to Santa than paying these moronic children. At least with Santa he'll give you a piece of coal instead of the middle finger.”

Typical Comment: Generally positive comments about this company from customers, with a number of glowing reviews.

They are also extremely reliable. I really like the guards as they are so polite and they look the part. There was a particularly difficult situation with someone aggressive and disruptive trying to get into the premises and that was handled with calm and professionalism. I have to say I was glad I had the guards on site who dealt with it brilliantly. Thank you"

It's been a pleasure working with them and I look forward to us continuing our partnership with them for many years to come."

They don’t make me feel safe at all & threatened to come into my home whenever they please, considering I’m a young female living alone this was very unsettling.

Google Review Stars: 4.9


Google Reviews Best: "SRS is our security provider for the Riverside House in Woolwich. We knew from the first meeting we are dealing not only with high level security professionals, but also very open minded and business orientated people. They told us of all options, gave recommendations on features they were not providing and in general we left the meeting having a clear understanding of what our needs are and how to cover them best. Unlike other meetings within the selection process we did not have a feeling of hard sales, but rather of a partnership approach. In the course of work SRS and in particular Yair showed themselves very flexible, reacting immediately to the changing situation and always acting in our best interest and for our comfort. We are overall very happy with SRS and highly recommend working with them. For ourselves we believe we have found a long term partner for securing our sites."
