Private Investigation Services in Birmingham

Covert Surveillance
Discreet surveillance can help establish a clear picture of a person's movements, activities and associations. Our Birmingham surveillance investigators gather photographic and video evidence supported by accurate operational records and reporting.
Infidelity Investigations
When there are genuine concerns about a partner's behaviour, speculation rarely provides the answers needed. We conduct discreet investigations designed to establish the facts while protecting client confidentiality throughout.
People Tracing
Our professional tracing service helps locate individuals throughout the UK for private, legal and commercial purposes. This may include tracing family members, former tenants, witnesses, beneficiaries or other individuals where there is a legitimate reason to establish their current address.
GPS Vehicle Tracking
Where appropriate and lawful, GPS tracking can provide valuable intelligence about vehicle movements over an extended period and can support wider surveillance enquiries.
Cohabitation Investigations
We assist clients and legal professionals where there are concerns that an individual's true living arrangements may differ from those being disclosed. Investigations can combine surveillance, research and other lawful enquiries to establish a clearer picture.
Background Checks
Our investigative background checks can help clients understand more about an individual or situation before making an important personal or commercial decision.
TSCM Bug Sweeping
Our Birmingham TSCM specialists inspect homes, offices and vehicles where there are concerns about hidden listening devices, covert cameras, GPS trackers or other technical surveillance threats.
A Lifetime of Dedicated Service

Sentry Private Investigators was founded by Ben Jones following a career in the British Armed Forces and more than a decade working within professional investigations.
Ben served with the Royal Green Jackets and later The Rifles, where operational service developed many of the skills that remain relevant to investigative work today: observation, planning, situational awareness, discipline and attention to detail.
Those principles continue to shape the way SPI approaches private investigations. We do not rely on assumptions or promise predetermined outcomes. Our investigators establish clear objectives, assess what can realistically and lawfully be achieved and gather evidence carefully and methodically.
SPI works with private individuals, businesses, solicitors and other professional clients who require confidentiality, dependable communication and an investigative service capable of standing up to scrutiny.

Private and Corporate Investigations

Private Investigations
Personal investigations often begin because something simply does not add up. A change in behaviour, unexplained movements, concerns surrounding a relationship or uncertainty about someone's whereabouts can create questions that are difficult to resolve without independent evidence.
SPI supports private clients with surveillance, infidelity investigations, cohabitation enquiries, people tracing, background checks, GPS tracking and other investigative services.
We understand that these enquiries can involve sensitive family, financial and relationship circumstances. Our investigators therefore work discreetly, avoid unnecessary intrusion and keep clients informed throughout the process.
The purpose of an investigation is not to confirm a client's suspicions at any cost. It is to establish the facts as objectively as possible.
Corporate Investigations
Businesses can face internal problems that are difficult to investigate using normal management procedures alone. Suspected employee misconduct, fraudulent absence, workplace theft, moonlighting and questionable injury claims can all have financial and operational consequences.
SPI provides discreet corporate investigation services to businesses in Birmingham and across the UK. Depending on the circumstances, an investigation may involve surveillance, background research, statement taking, tracing, evidence gathering or specialist technical services.
Our objective is to provide decision-makers with reliable information and properly documented findings so they can determine the appropriate next steps.

Infidelity Surveillance — Sutton Coldfield & Birmingham City Centre

Discuss an Investigation
SPI was contacted by a private client in Sutton Coldfield who had received information suggesting that his daughter's partner may have been involved in another relationship shortly before their planned wedding.
We were instructed to conduct discreet surveillance during a work Christmas event in Birmingham city centre.
After locating the subject at a nearby venue, our investigators maintained observations as the evening progressed. The subject was later seen leaving with another individual, and surveillance continued on foot through Birmingham city centre to a hotel.
Photographic evidence and a detailed account of the observations were provided privately to the client.
Although the findings were difficult for those involved, the investigation demonstrated the purpose of professional surveillance: to replace uncertainty and speculation with independently gathered factual evidence.
Every relationship investigation is different and an outcome can never be predetermined. If you have genuine concerns and would like to understand what can realistically be established, speak to our Birmingham investigation team in confidence.
