Time to update the EPC

It was with dismay that I read that EPCs had not been updated since they were launched in 2007 [Registered Gas Engineer, July 2022].

I had mine done three years ago. Over time, my house has had cavity wall insulation; a conservatory I built 30 years ago on the back has made the house warmer and easier to heat. I invested in solar PV in 2011 and it paid back in eight years and gives me 250 litres of hot water free most of the year. [I have] energy efficient glass and full loft insulation. I laid a new floor during lockdown and insulated under the floor.

I was dismayed to find that the panels could not be added as the surveyor said it would be counted as mains electric water heating? So instead of a nailed-on EPC of A, I only got a high B.

It’s definitely time to update the EPC. Martin Garside

Get the basics right to increase energy efficiency

Further to content promoting energy saving devices to ultimately encourage boilers to operate as close to dew point as possible for longer to achieve maximum efficiencies, although these can achieve a reduction in energy consumption, a structured approach is paramount.

We should all approach the subject using basic heat-loss protocols. Number one is keep fabric losses to a minimum, and so insulation and draughtproofing are the first things to address.

Issues surrounding inappropriate retrospective cavity wall insulation and spray-foam roof insulation should be carried out only with appropriate advice.

Heat recovery systems could be considered. And replacing primary heat sources should be carefully considered with a view to the long term.

Part L is yet adding to both installer and consumer confusion.

In my 1930s semi-detached home, I have a condensing combi that condenses in hot water mode, OpenTherm and outside sensor and, of course, the latest specification loft insulation. I’m currently looking at the viability of smart TRVs.

In conclusion: basics first and long-term cost effectiveness make financial sense. John Ward
