@James_Diamond can describe Hackney Fixers’ relationship with Hackney Council much better than I can, but in case he doesn’t get here in time …
Generally the relationship is good, but some points to think about …
Early on, it was difficult, because they only thought in terms of tonnage of waste, not what types of waste are involved, so make sure the conversation is about quality more than quantity.
Also, make sure that they understand that there are other aspects to this, such as community cohesion, and maybe see if you can talk to whoever is responsible for that area.
They may want the council’s name on your events, so be prepared for that and maybe use it as a negotiating tactic.
Having the council’s publicity on-side is definitely useful, so push them hard to get your events on their website, on noticeboards, in the council newspaper, if there is one etc.
Also, try to get editorial coverage, social media from executive and/or political accounts and suchlike, not just event listings.
Councils seem to move extremely slowly and it can be surprisingly complex, because, for example, things often have to be approved by multiple people (maybe in multiple departments), but once you’re in, you’re in and things become a lot easier because you’ve got implicit approval because you’re known to them already.
An example of this halo effect is that HF were given space in libraries to hold pop-up events and, again, that’s a separate department.
