How accurate are newbuild EPC?

[Fluffycloudland77]

I've just seen one for a newbuild house and it said £250 for heating and £90 for hot water for a 12 month period.

That can't be right surely?

does it have solar panels/heat pump already installed? Can't see it being likely otherwise, but EPCs are only a guess at the best of times.

Nope, just an A rated combi boiler.

Seems way to low to me.

EPCs are a joke. I have a two bed mid terrace. It has insulation, new boiler and new double glazing. We got bad rating on the EPC. Why? According to the 'surveyor' who did it, because we don't have a wind turbine or ground water heat pump. Its a suburban two bed mid terrace. WTF????

So no, just ignore it completely.

EPCs are a rough guide at best. They are generally done by a guy who has been on a course to input stuff into a computer programme. Generally they know nothing about buildings and if it doesn't fit exactly in their tickboxes they don't know how to deal with them.
Newer houses come under harsher building regs and therefore should in theory perform better and have lower builds. However due to an anomaly in how they do BR on large developments, buildings that do well on paper (design) don't always perform as well in real life (poor build quality) this isn't always the case but it has been known.
