<p>[holding answer 21 November 2013]: We are able to review the preliminary data we are collecting and regularly do so for example for the purpose of identifying inaccurate readings. We agreed to publish some examples of this information in our response to your request under the Environmental Information Regulations 2004 (sent 8 November 2013).</p><p>My officials have occasionally shown example preliminary data in presentations, for example at ground-source heat pump association conferences. We consider this a good opportunity to generate interest in the metering programme, including the installation of the metering equipment, and a forum that enables us to get feedback on the approach we are taking. The data's limitations can also be explained easily.</p>
