GivEnergy for a existing solar in Glasgow
Updated
Do not buy a new GivEnergy for a existing solar in Glasgow on the strength of an old brochure. Any new warranty for that Glasgow job has to come from a company that is still trading, not from a 2024 brochure.
GivEnergy on a existing solar in Glasgow
A tenement close is a consent and stair problem. A house in Bearsden can be an ordinary garage fit, which is the constraint I would write next to GivEnergy for this existing solar.
SP Energy Networks covers this Glasgow example. A 4 kWp-class roof at 860 kWh per kilowatt is about 3,440 kWh a year before shade, and GivEnergy does not change that weather.
Money for GivEnergy for a existing solar in Glasgow
Take a 13.5 kWh pack, cycled about 260 times, at 90% round trip. Charge at 13.0p, and value what comes back at 26.0p. Export given up is priced at 4.0p. About 2006 kWh a year of the charge is treated as spare solar from 4 kWp that might otherwise have been exported. Delivered energy is about 3159 kWh. After charging cost and lost export, the sketch saves about £562 a year. Set that against £8,204 fitted, which is a September 2026 illustration at the temporary 0% residential rate, not a quote. That is a simple payback of about 14.6 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 sketch prices the work at £8,204 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 existing solar in Glasgow
In Glasgow, on SP Energy Networks, 5 kW sits above the 3.68 kW G98 line, so this wants a G99 application before anyone energises it. Export can still be capped. Agree that before the inverter is ordered. The sketch uses 13.5 kWh and 4 kWp, which is enough to tell two quotes apart if they assumed something else.
For GivEnergy for a existing solar in Glasgow, check Companies House before a new warranty is promised. A GivEnergy already working in Glasgow is a repair conversation, not an order for another one.
Would I proceed with GivEnergy for a existing solar in Glasgow?
I would not treat backup as included on a 13.5 kWh quote unless the circuits are listed.
My default on GivEnergy for a existing solar in Glasgow 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. £8,204 is a September 2026 illustration for a 13.5 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 13.5 kWh sketch the inverter is 5 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 £8,204 job, that folder is part of what you bought.
What if the cheap rate is not 7p?
Then the sketch changes. This page used 13.0p as a charge rate and 26.0p 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.
