Surelock has been established for over 30 years, founded by highly decorated Senior Detective Roy Herridge QPM, now managed by former Senior Detective and past President of The Association of British Investigators Ron Harrison, we have a dedicated, highly skilled, and experienced team of professional private investigators and security consultants that work across the UK.

Initially an old-fashioned private detective company, now one of the most respected, offering so much more, we successfully provided our core services nationwide to business and private individuals, who have highly praised us over the years – https://www.surelock.org/testimonial  

Our Core Services

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, both here in the UK and abroad, for a wide range of clients, whether it be a burglary, robbery, blackmail, theft of valuable items, fraud, assaults, missing persons or indeed a murder, we can assist. At the end of the day, we will provide you with all the intelligence / evidence you need to progress the investigation, in legal or discipline proceedings – 

SURVEILLANCE

This is an integral part of many of our investigations. We have surveillance teams strategically placed all over UK to deal with domestic / cheating partner surveillance, accident injury surveillance, investigative surveillance and corporate surveillance. Our surveillance teams are led by former police / army personnel who have many years of experience. All our surveillance is carried out legally, covertly recorded in a public place, we keep the client informed of the findings, we supply a detailed log of events with selected photos, a full unedited recording is also available if required.

Domestic Surveillance

Accident injury Surveillance

Investigative Surveillance

Corporate Surveillance

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. Vulnerabilities identified in the survey will be highlighted, and cost-effective solutions will be provided in an easy-to-read illustrated report. 

Led by seasoned security consultant with over 30 years’ experience, Home Office trained with a wealth of knowledge in Crime Prevention and Anti-terrorism. A long standing and respected member of The Association of Security Consultants, was on the British Standards Institute (BSI) Security Services Committee for over 12 years and personally wrote the Security Consultancy and Private Investigations, Code of Practice standards that are now used regularly in the United Kingdom, as well as being involved in reviewing, updating & publishing most of the UK Security Codes of Practice and UK Security Standards in this industry

Now an expert on the implications and requirements of 

MARTYN’s LAW  ( The Terrorism (Protection of Premises) Act 2025)

Whilst awaiting for HM Government & the SIA to produce the 'Statutory Guidance policies' which will mainly focus on the requirements and regulation regime, at Surelock we have consultancy services, which detail all the security/protection aspects of Martyn's Law and can deal with all the legal requirements, registration and regulation advice required to you as a client to comply with this new law.

We are fully up to date and monitor every aspect/advice of NaCTSO - ProtectUK, Counter Terrorism Policing and other official bodies that may have input on these requirements of the law, although this does not come into force until 2027 there is much that needs planning and we can help

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. Our visits are covertly recorded for later use in training to improve and issues we identify at the time

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

BRAND PROTECTION

As one of the most experienced in UK instructed by some of the biggest brands in the world, we are specialists in Brand Protection and protect our client’s intellectual property rights, conducting numerous investigations and online take downs worldwide every single month. We utilise our specialist undercover and surveillance teams to gather intelligence, identifying the major criminals behind the counterfeit trade and where they are located. Working with the authorities on enforcement actions and prosecutions – with our pro-active investigations we are responsible for some of the largest seizures of counterfeits in UK, we also work alongside specialist lawyers in taking civil actions on behalf of our clients
