Hard-To-Treat-Cavity Review: Final Report
This report presents the results of our review of hard-to-treat cavity (HTTC) measures installed under ECO in 2013. The review consisted of a document review by energy companies and independent site audits of narrow HTTCs. The review enabled us to identify measures that were not eligible HTTCs and measures that had been incorrectly notified.
Background
Following the launch of ECO in January 2013 we became aware of possible inaccuracies in HTTCs under the CERO obligation. We launched a review of certain HTTC categories to identify the extent of the problems and published new guidance setting out fresh requirements for demonstrating the eligibility of HTTCs. These new requirements took effect from 1 January 2014.
Results
We concluded the HTTC review in late 2014 and our findings show that the savings attributed to all HTTC measures installed in 2013 will be reduced by approximately 105,000 tCO2. The results also show that there was improvement in the accuracy of HTTCs notified over the course of 2013. This suggests that early action by Ofgem with this issue improved compliance.
