Sentry Investigations are based at the Jewellery Quarter in the heart of Birmingham City. We have strong footholds in the East and West Midlands and we regularly operate in the linked areas listed below. If you need to hire a private investigator, get in touch and we will coordinate the free initial consultation.

  West Midlands 

  - Birmingham

  - Coventry

  - Dudley 

  - Sandwell

  - Solihull

  - Walsall

  - Wolverhampton


  East Midlands

  - Brackley

  - Corby

  - Derby

  - Kettering

  - Leicester

  - Loughborough

  - Northampton

  - Wellingborough


We operate with a selective network of private investigators who are vetted and approved by the Association of British Investigators (ABI). Although surveillance investigations require prior planning which can be fairly time consuming, we can deploy operatives within just a few hours (dependent on the type of investigation and availability of specialised operatives).
