Just phone the phone numbers on the "advertising stickers" on the CO2 FE's at work, leisure centre, library etc, chances are they will be local to you and see what the companies can offer. I pay £10 for a FE swap out from the number on our FE's at work.This would do me too Mike, i'm from Weston, work in Bristol and can't find anywhere yet, if I do i'll keep you in the know mate.
Try searching in google "fire Colchester". I saw a few give em a call. Some might not respond to email quickly. Just ask if they do fire extinguisher refills.
Just had my FE replaced at Griffin Fire and Training in Fareham, which is in between Portsmouth and Southampton, in Hampshire (hopefully those names will come in the search results). £20 to replace. Not the cheapest but very close for me.
