Am looking a solicitor to prosecute a small building company for fly tipping on my property have got it on cctv any recommendations

private law firms can't bring prosecutions. That's the domain of the CPS, DPP, DTI, etc. have you reported this to the police?

I'd be very surprised if the police were at all interested. They are notoriously not interested in doing very much if they dont have to; if the stuff being dumped is a health hazard you may want to contact environmental health or housing - not sure which. You'd probably need to demonstrate it isnt an isolated incident etc, etc, etc and there's some sort of intent or malice involved before you're likely to see them lift a finger.

I'd like to say they're all a bone idle lot but that's not strictly true - they're all so busily in to jobsworth stuff that they havent got time to do their jobs.
