GivEnergy for a EV household in Cardiff
Updated
Do not buy a new GivEnergy for a EV household in Cardiff on the strength of an old brochure. Any new warranty for that Cardiff job has to come from a company that is still trading, not from a 2024 brochure.
GivEnergy on a EV household in Cardiff
Roath terraces and Bay apartments fail for different reasons: shade and demise, which is the constraint I would write next to GivEnergy for this EV household.
National Grid Electricity Distribution covers this Cardiff example. A 4 kWp-class roof at 980 kWh per kilowatt is about 3,920 kWh a year before shade, and GivEnergy does not change that weather.
Money for GivEnergy for a EV household in Cardiff
Take a 10 kWh pack, cycled about 340 times, at 90% round trip. Charge at 11.0p, and value what comes back at 30.8p. Export given up is priced at 12.0p. About 1943 kWh a year of the charge is treated as spare solar from 4 kWp that might otherwise have been exported. Delivered energy is about 3060 kWh. After charging cost and lost export, the figure saves about £596 a year. Set that against £7,018 fitted, which is a September 2026 illustration at the temporary 0% residential rate, not a quote. That is a simple payback of about 11.8 years on these assumptions. Nudge the night rate up by 4p and see if you still like it.
Where the job is a qualifying install in a home, the 0% rate runs to 31 March 2027 and is due to become 5% after that. This figure prices the work at £7,018 on that basis. It does not apply to a shop, and it does not apply to a battery you buy and fit yourself.
Connection for GivEnergy for a EV household in Cardiff
In Cardiff, on National Grid Electricity Distribution, 3.6 kW is in the band where G98 connect-and-notify is often enough. Export can still be capped. Agree that before the inverter is ordered. The figure uses 10 kWh and 4 kWp, which is enough to tell two quotes apart if they assumed something else.
For GivEnergy for a EV household in Cardiff, check Companies House before a new warranty is promised. A GivEnergy already working in Cardiff is a repair conversation, not an order for another one.
Would I proceed with GivEnergy for a EV household in Cardiff?
I would not compare a £7,018 headline with another until usable kWh and the fate of any existing inverter match.
My default on GivEnergy for a EV household in Cardiff is no, unless written consent or a live warranty counterparty is already in the file.
Common questions
Is the price on this page a quote?
No. £7,018 is a September 2026 illustration for a 10 kWh example at the temporary 0% residential rate. Your survey replaces it.
Will it stay on in a power cut?
Only if a gateway or essential-load board was designed and paid for. A standard grid-tied battery turns off with the grid. On this 10 kWh example the inverter is 3.6 kW, and backup is still a separate line.
What paperwork should I keep?
Keep the MCS certificate where the job is certified, the electrical certificate, the DNO record, the schematic, the warranty registration and a photo of the schedule. For an illustrated £7,018 job, that folder is part of what you bought.
What if the cheap rate is not 7p?
Then the figure changes. This page used 11.0p as a charge rate and 30.8p as the rate avoided. A smaller gap means a worse payback. Read the live tariff.

The figures above are a rough guide. An installer still needs to see your fuse board, where the battery will go, and whether you want power during a blackout.
