Hi, I used to live in Chelmsford, I'd say the best place is Happy Bunnies boarding in earls colne near braintree. You should be able to find the details if you google it...the website doesn't look terribly good I don't think, but she has a fab bunny room (back of a converted garage) for housebunnies and is a very switched on vet nurse, so they'd be on good hands. I've used her several times and been very happy. Other than that, I have been to Hertfordshire and Surrey, because I haven't found anywhere else local that I'm happy with!!
