Explore Vehicle TrackingLocalPI has been conducting professional investigations throughout Windsor and the surrounding Berkshire area for over 25 years. Our experienced team knows this historic royal borough inside out, from the busy shopping areas around Windsor Castle to the quieter residential streets of Clewer and Old Windsor. This local knowledge proves invaluable when conducting surveillance operations or background investigations. We understand the traffic patterns along the A308 and A332, know which car parks offer the best vantage points for discreet observation, and recognise the difference between tourist activity around the Long Walk and genuine resident behaviour in areas like Dedworth or Spital. Our investigators regularly work across Windsor's diverse neighbourhoods, whether that's monitoring commercial premises near the railway station, conducting asset searches in the affluent areas around Virginia Water, or serving legal documents to businesses along the high street. We've tracked subjects through Windsor Great Park, maintained surveillance outside the Theatre Royal, and conducted investigations involving properties from the riverside apartments overlooking the Thames to the Victorian terraces in Clewer Village. What sets our Windsor operation apart is our team's professional background. All our investigators are ex-police or military personnel with extensive training in surveillance techniques, evidence gathering, and legal procedures. Whether you need surveillance services starting from £55 per hour, comprehensive background checks from £299, or technical surveillance countermeasures sweeping from £599, we handle each case with complete discretion. Our services extend beyond basic investigations to include asset tracing, process serving from £199, polygraph testing, and vehicle tracking solutions. We're fully registered with the Information Commissioner's Office for data protection compliance and carry comprehensive professional indemnity insurance. This means every investigation is conducted within strict legal guidelines while maintaining the confidentiality our Windsor clients expect. From matrimonial investigations to corporate due diligence, from insurance fraud cases to missing person searches, our Windsor team applies the same methodical approach that has made us one of the UK's most trusted private investigation companies. Call 0800 294 8556 to discuss your requirements with an experienced investigator who understands both your concerns and the local area where your case will unfold.
Why Choose LocalPI in Windsor
When you need professional investigation services in Windsor, working with local specialists makes the difference between results and wasted time. Our investigators know Berkshire intimately - from the narrow medieval streets around Windsor Castle to the modern business districts near the Great Western Railway station. This local knowledge means we can position surveillance teams effectively, understand traffic patterns for following subjects, and blend into communities without drawing attention. These organisations maintain strict professional standards and require ongoing training. Every case we handle follows established protocols, and our investigators must demonstrate continued competence through regular assessments. This matters when evidence needs to stand up in court or when client confidentiality is paramount. We believe in straight talking from day one. When you call 0800 294 8556, you'll speak directly with an experienced investigator - not a sales team reading from scripts. We'll explain exactly what we can and cannot do, provide realistic timelines, and won't make promises we can't keep. Many clients have been let down by investigators who oversell their capabilities or disappear when cases become complex. Our pricing structure is transparent from the start. Surveillance begins at £55 per hour, background checks from £299, and process serving from £199. No hidden charges, no inflated expenses, no surprise bills. We provide detailed cost breakdowns before starting work and update you if circumstances change. Having handled investigations for over 25 years, we know how quickly costs can spiral without proper management. Every investigator on our team comes from police or military backgrounds. They understand evidence handling, legal requirements, and professional conduct. We're fully insured with professional indemnity cover and registered with the Information Commissioner's Office for data protection compliance. Whether you need surveillance near Windsor Great Park, background checks for business partnerships, or process serving in Eton, our approach remains the same: thorough preparation, professional execution, and clear reporting. We've seen too many cases compromised by shortcuts or amateur methods.

Investigation Services in Windsor
Our Windsor office handles investigations across the Thames Valley region, from the Castle grounds to the business parks of Slough. Each case requires different skills and equipment, drawn from our 25-year track record in the field.
Matrimonial and Relationship Investigations
Suspicious partners often change their routines. We document behaviour patterns through careful surveillance, typically around Windsor Great Park or the town centre's restaurants and bars. Our investigators blend into local environments - whether it's the riverside walks near Eton or the car parks at Windsor Royal Shopping. We've tracked subjects from the railway station to London meetings, providing photographic evidence and detailed timelines. Many clients need proof for divorce proceedings or simply want to know the truth about their relationship.Employee Verification and Workplace Investigations
Windsor's mix of corporate headquarters and small businesses creates unique employment challenges. We verify credentials for senior appointments, particularly given the area's proximity to Heathrow and London's financial district. Sick leave abuse is common - we've followed supposedly injured employees from their homes near the racecourse to building sites in Reading. Theft investigations often involve CCTV analysis and discrete questioning. One recent case involved tracking stolen equipment from a Windsor office to a house in Maidenhead.Bug Sweeping for Businesses and Individuals
High-net-worth residents and successful businesses attract unwanted attention. Our technical surveillance countermeasures (TSCM) service uses professional equipment to detect hidden cameras, listening devices, and GPS trackers. We've swept boardrooms in Windsor's business centres and private homes backing onto Windsor Great Park. Commercial espionage is real - competitors plant devices during meetings or site visits. Our sweeps typically take 2-4 hours and include written reports with photographic evidence.Asset Tracing During Divorces or Debt Recovery
Windsor's wealthy residents sometimes hide assets during divorce proceedings. We trace property ownership, offshore accounts, and business interests across Berkshire and beyond. Recent cases involved tracking assets from Windsor properties to companies registered in the Channel Islands. For debt recovery, we locate hidden vehicles, valuable collections, and undisclosed income streams. Our investigators work with solicitors to ensure all findings meet legal requirements.Process Serving for Legal Documents
Serving legal papers requires local knowledge and persistence. Defendants often avoid service by changing addresses or working irregular hours. We know Windsor's residential areas from Old Windsor to Dedworth, and we understand commuter patterns through the railway station. Difficult serves might require multiple visits over several days. Our process servers are trained in legal requirements and provide sworn affidavits when service is completed.Missing Persons Enquiries
People disappear for various reasons - family disputes, financial problems, or mental health issues. We start with last known addresses and work outwards, checking local hospitals, hostels, and transport links. Windsor's position between London and the West Country means missing persons often travel considerable distances. We coordinate with police when appropriate and maintain sensitivity throughout these emotional investigations.Frequently Asked Questions

We provide a comprehensive final report with all evidence, photographs, and our professional conclusions within 48 hours of completion.
What happens if you don't find what we're looking for?
Sometimes investigations don't uncover the expected results, but this is still valuable information that can help your decision-making. You only pay for work completed, and we'll explain our findings thoroughly, including why certain evidence wasn't located. We often recommend alternative approaches or additional searches that might yield better results.
