Surelock has been established for over 30 years, during that time we have successfully provided our professional services to many companies and various businesses, either on a retainer basis or on a case-by-case basis. We have a particular expertise in the tool / plant hire and construction industries.

We offer a variety of services to corporate businesses: -

Here are a few of our Core Services which we may be able to help you with -

CRIME / FRAUD INVESTIGATIONS

This is really our bread and butter, we have a dedicated team of highly experienced investigators who over the years have successfully investigated most crimes, for a wide range of clients, whether it be a burglary, robbery, theft, fraud, assaults, we can assist. We investigate, interview staff and suspects, will provide you with all the intelligence / evidence you need to progress the investigation, in legal or discipline proceedings or report and liaise with the police on your behalf –

SURVEILLANCE

We have surveillance teams strategically placed all over UK to deal with employee absenteeism, accident injury claims, allegations of theft and corporate investigations. All our surveillance is carried out legally, covertly recorded in a public place, we keep the client informed of the findings, supplying a detailed log of events with selected photos, a full unedited recording is also available if required.

Security Surveys

We have many years experienced in the field of security surveys / risk assessments, dealing with physical security measures both existing and future installations, either as a result of an incident or for a greenfield site. Vulnerabilities identified in the survey will be highlighted, and cost-effective solutions will be provided in an easy-to-read illustrated report. We also carry out vehicle load security checks to establish if they conform to the company’s procedures. Our surveyors are fully accredited by the appropriate bodies under Home Office guidelines and have the necessary security clearance with over 30 years of experience –

PENETRATIONS TESTS

Following a security survey how often do you get your security measures tested, don’t wait for the inevitable to happen! Physical penetration tests are an important way for businesses to identify any weaknesses in the security of their premises (e.g., warehouses and offices) that could be exploited by criminals – 

BUG SWEEPS

We have a dedicated engineer who has over 30 years’ experience, using purpose-built specialist equipment. Working with a backup team we conduct a full electronic sweep of the premises, then use separate handheld wands for near field examinations of the respective rooms / offices, computers, and telephone equipment, finally very importantly a finger-tip search examining power supplies, ceiling tiles, thus when we complete an TSCM (Technical Surveillance Countermeasures Sweep), we can tell you if there is anything there or not. “What you say in private is your business, keeping it that way is ours” 

COMPANY INFILTRATION SERVICES

If you suspect something is going on in your company, it can feel uncomfortable to even think about... let alone act. That is why our company infiltration services are designed to suit the structure of your company and the unique circumstances you find yourselves in.

Our investigators fit seamlessly in the workplace, so that they can establish the truth for you and gather any evidence which you may require to take action.

MYSTERY SHOPPER – TEST PURCHASES

Mystery shopping and test purchasing are essential tools for businesses to gain valuable insights into their operations, evaluate customer experiences, and identify areas for improvement. By simulating real customer interactions, these services provide objective feedback and actionable recommendations. Also, on occasions they discover wrongdoing and criminal matters.

All our test purchase visits are covertly recorded, and this evidence can be used to improve service and for training purposes.
