Warren Report reveals poor state of UK housing stock thanks to new EPC data

The Warren Report, a column penned by the chairman of the British Energy Efficiency Foundation, Andrew Warren has revealed the poor state of energy efficiency in UK housing stock. This follows the release of a ground-breaking new ONS report.

The recently completed analysis of Energy Performance Certificate (EPC) data highlights poor progress in improving the energy efficiency of UK housing stock in recent years. The Warren Report claims that almost half the energy we use in the UK each year is used in buildings, two thirds of that from homes, of which many are draughty and poorly insulated and not energy efficient.

And despite the Clean Growth Strategy launched by government around 3 years ago, little progress has been made. At the time the Clean Growth Minister stated that: “All housing stock should be up to at least band C by 2035”. The report highlighted that last year the average energy efficiency rating for an existing house was band D.

The analysis comes about as half the homes in England and Wales now have an EPC rating. This enables the Office for National Statistics (ONS) to publish such detailed analysis on its first ever exposé of Energy Performance data.

The Warren report communicates that the ONS data reveals, in some cases, some new build properties have an even worse EPC rating than existing properties in the same area. Shockingly this spans across 14 local authorities.

The report concludes by saying that “EPCs for building remain a great concept. But only if they are accurately assessed. And all transgressions pursued.”

Andrew Parkin, Stroma Director of Energy Certification said: “This excellent article from Andrew Warren is well worth a read - distilling out some of the more concerning results from ONS data released on the energy performance of our dwellings. New building regulations are coming but we cannot allow the current state of play to exist for much longer and we must ensure the new rules don't allow dwellings (particularly conversions) to be rated so poorly and still meet the regulations. We need the SAP/RdSAP methodologies to be updated shortly after the regulations are set to ensure accurate assessment.”
