What does this event cover

Reading the economic tea leaves has always been as much art as science.

For the first time since 2015, BERL has reweighted the adjustors and cost index to better reflect sector spending patterns. They’ve also dug into non–tier one statistics, especially around infrastructure costs, to test and refine what the econometric models are telling us.

In this webinar, Killian Destremau, BERL’s Deputy Chief Economist, will:

  • Explain what has changed in the adjustors and why
  • Highlight the key drivers behind the new Local Government Cost Index
  • Explore what the current economic signals mean for councils heading into LTP 2027
  • Share tips for responding to those tough economic questions in council workshops

With the cost-of-living front and centre as we approach the 2026 election year, this is your chance to cut through the noise and get a clear view of what lies ahead.

Whether you regularly use the adjustors, are managing an LTP project, or just want to understand the medium-term outlook, this session will give you the insights you need.
