We have successfully provided our core services nationwide to business and private individuals, who have highly praised us over the years

Core Services

BRAND PROTECTION

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. Working with the authorities on enforcement action and prosecutions – with our pro-active investigations we are responsible for some of the largest seizures of counterfeits in UK -

SURVELLANCE

We have surveillance teams strategically placed all over UK to deal with domestic / cheating partner surveillance, accident injury surveillance, investigative surveillance and corporate surveillance 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

Our domestic surveillance services help uncover the truth in sensitive personal matters. Whether you're dealing with suspected infidelity, child custody concerns, or other private disputes, our experienced team discreetly gathers evidence using legally compliant methods. With compassion and confidentiality at the core, we provide clear insights to support informed decisions.

Accident injury Surveillance

Accident injury surveillance is essential when there's doubt about the legitimacy of a personal injury claim. We conduct detailed, lawful monitoring to assess the validity of a claimant’s reported injuries and behaviours. Our findings can be used in court or during settlement discussions, helping businesses, insurers, and legal teams protect against fraudulent or exaggerated claims.

Investigative Surveillance

Our investigative surveillance services offer tailored solutions for complex situations requiring deeper insight. Whether you're dealing with fraud, theft, or other forms of misconduct, our skilled investigators combine technology with traditional methods to collect accurate, admissible evidence. Each operation is planned carefully to meet your objectives while maintaining full legal compliance.

Corporate Surveillance

Protect your business from internal threats and unethical practices with our corporate surveillance services. We support companies facing issues like employee misconduct, intellectual property theft, and suspicious behaviour. By monitoring key activity discreetly and professionally, we deliver the evidence you need to take action and safeguard your operations.

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.

MARTYN’s LAW

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 imput on these requirements of the law.

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.

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 –
