Home battery installation in Glasgow
Updated
Glasgow tenements dominate large parts of the city. A close, a flat roof and a shared stair are a different design problem from a semi in Bearsden or Newton Mearns, where a garage install looks much more like the English suburban pattern.
The houses, not the postcode average
Tenement roofs are usually common property. A top-floor owner often cannot decide alone to put panels or a cable across them. Suburban pitched roofs are the realistic solar-plus-battery market.
Without a private roof or a garage, a battery-only arbitrage install still needs a safe internal position and a connection agreement. It does not need a fantasy about tenement solar.
Tenement stairs and no lift are a manual-handling issue for cabinets that can exceed 50 to 100 kg.
What gets fitted here
The installs that proceed are usually houses with a driveway and a cool garage, paired with a modest array and a tariff that has a real overnight or export gap.
Scottish winter solar is poor. Anyone quoting a one-year payback from a Glasgow roof in December is skipping the weather.
SP Energy Networks, yield and a 4 kWp example
A 4 kWp array at 860 kWh per installed kilowatt is about 3,440 kWh a year before shade. That is the local ceiling on solar charging, not a promise the battery will cycle fully in January.
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 figure uses 8 kWh and 4 kWp, which is enough to tell two quotes apart if they assumed something else.
Take an 8 kWh pack, cycled about 300 times, at 90% round trip. Charge at 9.0p, and value what comes back at 28.4p. Export given up is priced at 8.0p. About 1371 kWh a year of the charge is treated as spare solar from 4 kWp that might otherwise have been exported. Delivered energy is about 2160 kWh. After charging cost and lost export, the figure saves about £433 a year. Set that against £6,448 fitted, which is a September 2026 illustration at the temporary 0% residential rate, not a quote. That is a simple payback of about 14.9 years on these assumptions. Nudge the night rate up by 4p and see if you still like it.
What I would not sign in Glasgow
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 £6,448 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 £6,448 before the DNO route for a 5 kW inverter is known.
A tenement close is a consent and stair problem. A house in Bearsden can be an ordinary garage fit.
Common questions
Is the price on this page a quote?
No. £6,448 is a September 2026 illustration for a 8 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 8 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 £6,448 job, that folder is part of what you bought.
What if the cheap rate is not 7p?
Then the figure changes. This page used 9.0p as a charge rate and 28.4p 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.
