Window tinting recommendations?

[un1corn]

Just after some prices for a c-class, tints on all windows except front doors. Sort of 50% tints, not full on FBI style black.

Any recommendations in the North west area? Specifically Blackpool/Preston way but will consider a bit further if really good/cheap.

Please don't think that I'm coming across as rude, but why do you want to tint the rear windows of your car?

Is it for aesthetic reasons, so the car looks nicer?

I'm genuinely baffled, please enlighten me as I've never had the inkling to make my car windows darker.

It's an estate and I don't like too much light getting in. It feels like i'm driving around in a greenhouse at the moment.
