Our existing energy provider is OVO. We pay 14.5p per kW and feed-in-tariff is registered with them.

Our DNO IS Scottish Power and they wonít fit an Economy 7 meter.

Our contract with OVO is coming to an end, and they want to increase our fee to 15.7p. I was going to shop around, and if I find a new cheaper provider  does anyone know what happens to our FiT payments? Do I need to register again with the new provider?

We have an air source heat pump, so I need the best unit rate we can get.

No, your FIT account is a stand alone account and does not tie you to the same supplier for your import energy.

Why would they not fit a E7 meter ? I guess it would have worked out more expensive though.
Your consumption of 2800kwh for 4 summer months seems a lot with no CH on. What other big consumer do you have?

We have an ASHP, which consumes power. I have tried to figure out what other culprits there are... we have three fridges, use the oven and the tumble dryer. We also work from home. I agree, our consumption is high, but canít figure out how to pinpoint the energy drain. We also changed all bulbs to LED. Itís confusing.

Yes, funny enough I have just answered a similar query, see this old thread  -  https://www.navitron.org.uk/forum/index.php/topic,30152.0.html

The consensus was not too complimentary.

 I believe you need to make some effort to identify why your consumption is so high. The Av consumption for a UK house is reckoned to be about 3600kwh/yr but this would not include your HP.

 I presume that the CH is not on but the HP is used for the HW.  Could it be that for this purpose your HP is cycling during the day ?  The start and stop losses connected to cycling can be huge. Imagine every time the HP switches on it has to heat the Mc, all the pipes and all the stagnant water, energy that is lost.  The HP needs to do the HW once a day and then switch off.  You could probably detect the amount of energy being used by looking at the meter during the event but the better way is to have the HP hard wired to meter.

Check your fridges have not run out of gas and are permanently on, i had this with a freezer.

The stand by losses from IT equipment can be considerable. check by plugging in using a plug in meter.

Why pay for leccy you dont need.

My fridge/freezer sucks the most power in my house, typically 2 kWh per 24hr day. This is 87% of my grid-use. If I had a lithium battery this would drop dramatically.

We use Pure Planet for our gas n electric. All renewable electricity and gas is carbon offset with tree planting and such. We pay a membership fee (£15 a month I think) and we get our energy at the wholesale price (thereís no markup by pure planet). Everything is run from an app on my phone, and you get a monthly notification to tell you to send a meter reading.

We have our FIT payments with Good Energy.

Yes, not good at all. Also saw this:

They also have or had a director who was also associated at some time with the following infamous energy suppliers:

GB Energy Supply Ltd - in Liquidation
Future Energy Utilities Ltd - Dissolved
Our Power Energy Supply Ltd - in Administration
Brilliant Energy Supply Ltd - in Administartion

Great points Ken.

Our HW does muddy our numbers - we have an iBoost installed which basically takes excess solar and uses it to heat water via the immersion heater - our SolarEdge app sees this as consumption, which it's not (well, I suppose it is), because it doesn't appear on our electricity metre. But yes, on bad solar days, the ASHP takes care of DHW and it's not been cold enough at the moment for it to heat the house, so I can imagine there's lost energy there. For sure.

Our fridges are brand new, so gas shouldn't be an issue.

About the plugin meter, where can I buy one of these? Do you have any suggestions?

Thanks Iain.

Do I need an army of these, or would 1 or 2 suffice and let them run for a few days jotting down usage?

That explains the high usage, what is your actual elecy import over those months ?

For example I live in an ordinary 3 bed house and my usage May to July this year is around 2,500 kWh's. That sounds high too, but it includes, battery losses, occasional heat pump use, Immersun diversion to hot water and some dumping excess power to storage heaters. I also exported around 1,000 kWh's which I did not use.

However, because of all my PV and batteries, my actual import over those 3 months was only 4 kWh's.

Nowty, And presumably charging your EV. I admire your commitment to being green. Are you in the trade or have you bought all your kit retail?
