    Default EPCs based on RdSAP - Evohome

    I am going through the process of a getting an EPC for our property. As it is a 2001 build, the EPC is based on RdSAP.

    The surveyor was a pleasant enough guy but he really wasn't interested in my boiler or Evohome. Indeed, when pressed, he just shrugged his shoulders and said what I needed was a full SAP survey. My reading of the latest RdSAP guidelines suggests that houses with 2 or more time/temperature controlled zones will have these taken into account in the final calculation. It also suggests that I should have been asked about such mundane things as the commissioned/design boiler max flow temperature. My boiler settings parameter has been set at 70C max flow.

    The only reason that I am making a fuss is because I would like the EPC to be accurate, and I would have thought that Evohome/Opentherm (class 8 ErP) would have had some impact on the EPC calculation.

    Its making me wonder whether I should pay to have Evohome disconnected and take it with me if we decide to sell.

    When I had mine done, my surveyor did mention individual room zoning on the report.

    Thanks Bruce. My guy had written down that I had a B - rated boiler in his notes and no pump! I pointed out, amongst other things, that my boiler is actually ‘A+’ rated with Opentherm control and that the pump is located within the boiler casing and not in the airing cupboard.

    When I raised my concerns with my Estate Agent, as he is their assessor of choice, the response was ‘he is available and quick’! I would probably add ‘incompetent and cheap’. The assessor has since admitted that he isn’t up to speed on the December 2017 changes.

    Having looked at recent EPCs for similar properties in my area, I am looking forward to being told that I need to spend £8000 on floor insulation to save £80 a year. A bargain.

    If there is no visible pump, was he expecting mains pressure to circulate the CH water?

    He rang me this afternoon to say that he had inputted all his data for my timber-framed house, and his was running the EPC. He went very quiet when I pointed out that my home is standard brick and breeze block construction with cavity insulation. I hadn’t the heart to ask about the pump. My Estate Agent has agreed to another audit at their expense.

    Did he not spot the cling film used as double glazing too?

    Do any prospective buyers take any notice of the EPC? It's just another job creation scheme but I suppose it keeps some folks off the streets.

    The EPC makes a difference if you are planning on getting any Grants.

    You also need it for a FIT application if you have solar panels or any other form of microgeneration.
