3 Available gas boiler engineers (n = 18) Randomisation Control 6 engineers perform gas safety checks as per normal Advice 6 engineers perform gas safety checks and deliver advice Leaflet 6 engineers perform gas safety checks and leave leaflet Two meter readings, in m 3 or f 3 converted to kWh Outcome Household kWh used during trial, winter months Outcome Household kWh used during trial, winter months Outcome Household kWh used during trial, winter months Trial design

4 Delivery and evaluation timeline 4Results from Newcastle heating controls advice trial

5 Who participated? Summary of meter read return rates 1 st readings2 nd readingsConversion % Usable observations Leaflet Advice Control Total Results from Newcastle heating controls advice trial

6 …from which types of homes? 6Results from Newcastle heating controls advice trial

7 …with what kinds of heating controls? 7Results from Newcastle heating controls advice trial

8 What was the impact? No significant overall reduction in gas consumption during the trial period for advice or information Analysis controlling for different characteristics of the three groups (physical housing characteristics, pre-paid meters, engineer) also identified no impact Analysis provides coherent evidence on the predictors of energy use, such as number of bedrooms 8Results from Newcastle heating controls advice trial

9 What did we learn about the process? Range of individual level impacts Knowledge, behavioural and impacts identified Influenced by household composition, occupancy, circumstance Why no impact at the aggregate level? Link between knowledge and behaviour; behaviour change not always leading to more efficient energy use Key learning Advice described as having greater influence, leaflet as memory aid; trusted messenger effective mechanism 9Results from Newcastle heating controls advice trial

10 Learning for future trials: Boiler engineers were trusted messengers and valued Meter reading analysis possible - but Smart Meters would be better Practical lessons around implementing this kind of intervention – inc. successful delivery partnership 10Results from Newcastle heating controls advice trial
