Repairer recommendations near Cheltenham

Posted here for greater exposure, Mods please move if appropriate.

Long story short (might elaborate in another post in due course), but MrsCarp and the 2 tiny carps were shunted from behind today and the Octavia is a mess.  All occupants OK, but I'm looking for a personal recommendation for a bodyshop in the Cheltenham, Bishops Cleeve, Tewkesbury triangle (or further afield if they'll collect and deliver).

I haven't had a chance to have a good look in daylight, but as a minimum it'll need:-

New rear bumper with reversing sensors

New tailgate

New n/s/r light cluster

Respray and blend new panels

I suspect that the floor pan and/or roof will need a little straightening too, so wouldn't be entirely surprised if it was written off.   Hoping not though.

However, having seen so many horror stories on here and elsewhere about the big national 'insurance approved' repairers, I was looking around for suggestions.   We need a decision by tomorrow morning, when the replacement vehicle will be delivered.   Both insurances being great (so far), particularly the other company, who have accepted all responsibility.

Thanks in advance,

Sam
