Security and Safety Solutions provides discreet private investigation and covert surveillance for businesses, law firms and private clients in London and across the UK.

Private Investigators in London and Across the UK

Our investigations are led by a former Army Officer in the Royal Military Police with more than 15 years’ experience of corporate investigations. That means cases are planned properly, evidence is gathered and recorded the way a court expects, and you get clear answers you can act on.

Whether you need due diligence before a deal, the truth behind an insurance claim, a missing person traced or legal papers served, we handle every case with complete confidentiality.

Security and Safety Solutions is a trading name of Chestnut Risk Ltd, which is registered with the Information Commissioner’s Office (ZC293036).

Surveillance

Covert Surveillance Across the UK

Surveillance is where a case is usually won or lost. Done well, it produces a clear, timed record of what someone did. Done badly, it alerts the subject and the opportunity is gone.

  • Static surveillance: observing a location from a vehicle or a suitable observation point.
  • Mobile surveillance: experienced teams on foot and in vehicles, so a subject can be followed through a city or across the country.
  • Mixed-gender teams: so operatives blend in wherever the subject goes.
  • Timed logs, photographs and video: recorded from public places, with nothing edited out.

Most mobile surveillance needs two or three operatives to be done properly. We will tell you honestly what your case needs, and when surveillance is not the right tool.

Counter-surveillance

Counter-Surveillance and Bug Sweeps (TSCM)

If you think you are being watched, followed or listened to, we can find out. This is a natural extension of our close protection work, where spotting hostile surveillance is part of keeping a principal safe.

  • Surveillance detection: a discreet team watches the people watching you, on foot, in vehicles or around your home and office.
  • Technical sweeps (TSCM): our own specialist consultants sweep boardrooms, offices, homes and vehicles for listening devices, hidden cameras and trackers. For private homes, see our residential technical surveillance sweeps.
  • Advice afterwards: what was found, what it means, and how to tighten your routines and security.

For families and executives who already use our close protection in London, counter-surveillance can be built into the security plan.

How it works

How an Investigation Works

  • 1. Confidential conversation: you tell us what has happened and what you need to know. We make sure we are the right firm for it.
  • 2. Initial search, £400: we establish the facts already available and the best way forward for the investigation.
  • 3. Agreed cost programme: we set out the full plan, the operatives and hours needed, and the cost, for you to agree before any further work starts.
  • 4. Investigation: our team carries out the enquiries or surveillance, with updates to you at agreed points.
  • 5. Report: a clear written report with timed logs, photographs and video, and witness statements where the case needs them.

We treat evidence the way a court expects: contemporaneous notes, original unedited footage kept securely, and a clear record of who handled what. That gives your solicitor the best chance of using it.

Coverage

Private Investigators in London, Across the UK and Overseas

We are based in London and work throughout England, Scotland and Wales, including the Home Counties, the Midlands, Manchester, Liverpool, Yorkshire, Bristol and the South West.

When a case leads abroad, we can follow it. Enquiries overseas are led by our UK team and, where needed, carried out with vetted local partners who work within the law of that country. You keep one point of contact and one report.

Confidentiality and cost

Confidential, Proportionate and Clearly Priced

Every case is handled in complete confidence. We hold personal data securely under UK GDPR and the Data Protection Act 2018, and we only take on work where the reason is legitimate. We will not locate anyone where we believe it could put them at risk.

How much does a private investigator cost?

Every investigation starts with an initial search, costing £400. This establishes the facts and the best way forward. We then set out a full cost programme for you to agree before any further work starts, so there are no surprises.

FAQs

Frequently Asked Questions About Private Investigators

Will the person know they are being watched?2026-11-12T06:58:25+00:00

Not if the surveillance is done properly. Our operatives are trained to blend in, and we would rather stop and try another day than risk being noticed. If there is a risk of compromise, we will tell you and agree the next step.

How long does surveillance take?2026-11-12T06:58:25+00:00

Some questions are answered in a single day. Others need several days spread over a few weeks, timed around when the activity is most likely to happen. We plan the shortest effective operation and review it with you as results come in.

How do I know if I am being followed or bugged?2026-11-12T06:58:24+00:00

Warning signs include the same people or vehicles appearing around you, others knowing about private conversations, and unexplained devices or changes in your home, office or car. Our surveillance detection teams and technical sweeps can confirm whether anyone is watching or listening.

Do you serve legal documents?2026-11-12T06:58:24+00:00

Yes. We serve court papers and other legal documents across the UK, and provide a signed statement of service as proof for your solicitor or the court.

How much does a private investigator cost in the UK?2026-11-12T06:58:24+00:00

Every investigation starts with an initial search, costing £400, which establishes the facts and the best way forward. We then set out a full cost programme, including the operatives and hours needed, for you to agree before any further work starts.

Are private investigators licensed in the UK?2026-11-12T06:58:24+00:00

No. Licensing of private investigators was planned under the Private Security Industry Act 2001 but has never been brought into force. That makes it important to choose an experienced firm that works to clear standards. Security and Safety Solutions is a trading name of Chestnut Risk Ltd, which is registered with the ICO (ZC293036).

Can surveillance evidence be used in court?2026-11-12T06:58:23+00:00

Evidence that is properly gathered and recorded is regularly used in civil, family and employment cases. We keep contemporaneous logs, original unedited footage and a clear record of handling, and can provide witness statements. Whether a court admits evidence is always a matter for the court.

Can you trace a missing person?2026-11-12T06:58:23+00:00

Yes. We trace relatives, witnesses, debtors and people who have lost touch, using open-source research, enquiries and, where needed, field work. Before we pass on anyone’s whereabouts, we check the reason is legitimate and that it will not put them at risk.

Can a private investigator track a phone or put a tracker on a car?2026-11-12T06:58:23+00:00

No. A private investigator cannot access or track another person’s phone. Fitting a tracker to a vehicle without the owner’s or keeper’s consent also risks breaking the law. We only use trackers on vehicles the client owns or is entitled to authorise, such as company fleet vehicles, and only where it is justified.

Can a private investigator help with domestic abuse or a violent partner?2026-11-12T06:58:22+00:00

Yes. We gather evidence of abuse, threats and breaches of court orders that can support a police report, a non-molestation order or family court proceedings, working alongside your solicitor. We can also check whether a current or former partner is following you, tracking your car or monitoring your home. If you are in immediate danger, call 999 first.

Is it legal to hire a private investigator in the UK?2026-11-12T06:58:22+00:00

Yes. Hiring a private investigator is legal, provided the reason for the investigation and the methods used are legal. Investigators must comply with data protection law, harassment law and the criminal law like anyone else. We check the purpose of every case before we accept it.
