Trusted Private Detective Agency in Birmingham 
Ben Jones  Sentry Private Investigators Birmingham

Trust between clients and private investigators in the UK is a key factor which determines whether a client will, or will not proceed with proposed services. This is partly due to the fact that clients will often need to disclose details of their vulnerable or distressing situations. The UK private investigations industry is currently without regulation imposed by any governing body. This alone creates an additional hurdle when building strong levels of trust. This is also why it is essential for those seeking surveillance services to conduct their own research into potential agencies. Unfortunately there are many rogue private investigators operating throughout the UK who promise results, charge extortionate rates and fail to deliver before disappearing of the face of the earth. SPI are different. We are realistic and upfront with potential outcomes because we understand the complexities and legal boundaries we are limited to operate within. What we do promise is that we will use every resource available to us including our select network of expert private detectives in the UK who are motivated and willing to  go the extra mile to ensure our best chances of a successful outcome.
