Home battery installation in Reading
Updated
Reading is a commuter town of Victorian terraces, semis and flats. Many households are a good technical fit for a battery and a poor fit if they are leaseholders without a garage.
The houses, not the postcode average
Suburban south and east-west roofs are usable. Terraces near the centre are smaller.
SSEN connection rules and a crowded single-phase supply are the two checks that change the quote.
Station-area parking and terraces are slower than the outer estates.
What gets fitted here
Solar plus 10 kWh and a driveway charger is a familiar brief in the wider built-up area.
Use a winter week in the savings note so the customer sees the overnight-charge dependence.
SSEN, yield and a 4 kWp example
A 4 kWp array at 1010 kWh per installed kilowatt is about 4,040 kWh a year before shade. That is the local ceiling on solar charging, not a promise the battery will cycle fully in January.
In Reading, on SSEN, 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 figure uses 13.5 kWh and 6 kWp, which is enough to tell two quotes apart if they assumed something else.
Take a 13.5 kWh pack, cycled about 280 times, at 90% round trip. Charge at 13.0p, and value what comes back at 27.2p. Export given up is priced at 6.0p. About 2646 kWh a year of the charge is treated as spare solar from 6 kWp that might otherwise have been exported. Delivered energy is about 3402 kWh. After charging cost and lost export, the figure saves about £651 a year. Set that against £9,245 fitted, which is a September 2026 illustration at the temporary 0% residential rate, not a quote. That is a simple payback of about 14.2 years on these assumptions. Nudge the night rate up by 4p and see if you still like it.
What I would not sign in Reading
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 £9,245 on that basis. It does not apply to a shop, and it does not apply to a battery you buy and fit yourself.
I would not pay the bulk of £9,245 before the DNO route for a 5 kW inverter is known.
Commuter semis can take a proper system. A flat without a garage usually cannot.
Common questions
Is the price on this page a quote?
No. £9,245 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 example 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 £9,245 job, that folder is part of what you bought.
What if the cheap rate is not 7p?
Then the figure changes. This page used 13.0p as a charge rate and 27.2p as the rate avoided. A smaller gap means a worse payback. Read the live tariff.

Want a price for your house?
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.
