Your local council can often lend you (or give you) much of the litter-picking equipment that you need. But, as we have commented elsewhere, it may be risky always relying on borrowing equipment from your council, especially if there are other groups after it at the same time, so here are a few suggestions about where to obtain equipment

Ask the contact at your local council where they buy their equipment – they might be able to get you good rates. You can often find all the equipment that you need at reasonable prices from your local shops (e.g. hardware store, DIY shed, garden centre, etc.) or on E-Bay.

There are also many local suppliers who can be found in the appropriate section of Yellow Pages (try “cleaning materials”, “janitorial supplies” or “workwear”)

Below is a selection of suppliers who sell via the internet. Please let us know of any others you have used and we will add them to the list :
