Just wondering if it's worth me getting the gas and electric metre changed?

I'm just thinking this would help improve the EPC rating. The current EPC runs out in Dec. Has anyone had them fitted?

Hippogriff

Would it?

I didn't know that.

Radiator thermostats, yeah. A brand spanking new boiler, yeah. LED lights, yeah. All types of insulation, yeah.

But something that just measures your consumption? Whether smart, pre-pay or post-pay(?)... does it make a difference to the EPC? Have you validated this?

raiden

Apparently so but British have no appointments until further notice and I'm on a waiting list and the cost is 0. So hopefully I'll get them done soon

Hippogriff

Apparently so you've validated this or apparently so it does (which is not validating it)?

One of my properties had such a meter,put in by the tenants without my knowledge. Subsequent tenants changed back to a billed account because pre-paid works out very expensive. I don't like them,and I cannot see any way in which they could improve EPC rating. How would that work?

Inspector

I'm under the impression that Smart meters can help people be more energy efficient but won't actually change the EPC rating. I could be wrong.

Currently, the presence of smart meters are not an input into the Standard Assessment Procedure EPC calculation.

Nor will they affect the EPC calculation in the 2022 revised SAP 10.2 - but their presence may be noted on the EPC.

See https://bregroup.com/sap/sap10/ and follow the 'SAP 10.2 specification (21/04/2022)' link to open the PDF: 'The Government's Standard Assessment
Procedure for Energy Rating of Dwellings'.

Section 12.3 says:

"SAP software should allow assessors to record whether a smart electricity meter is fitted. This does not affect the results of the SAP calculation but may be referenced in the EPC."

Likewise for a gas smart meter (section 12.4.1)

A few websites said smart metres can improve your EPC rating? I thought before I have to renew mine might as well do it just incase that new rating comes into force in 2025.

Yes, some websites do say that. But they are wrong. And sometimes they confuse smart meter with smart thermostat.

No harm in doing so.

The SAP 10.2 revision to come into force this year is clear. Smart meters will not affect the EPC rating calculation.
I think it unlikely that SAP 11 (intended to apply to new builds from 2025) will change this.
