Thinking about Brent Council's budget again, I wonder what is expected from the LoHac agreement? I introduced this at the Brent Executive back in 2012. As I recall, officers were cautious in their estimates of savings, as it was a new contract of a very different type to the ones we had done before.
The logic is one of shared services giving economy of scale. When it was introduced in 2013, only Brent and Barnet came on (as new Boroughs join as their existing contracts expire). By now, many more Boroughs should have joined, and therefore the savings should be greater.
