Capture your solar generation, lock in cheap overnight tariffs, and stop paying peak rates for electricity you could have stored yourself.
The monthly electricity bill dropped from £600 to £24.79, around £6,900 saved a year, after the heat pump was also re-commissioned with the correct flow temperature.
“We’ve had very attentive customer service from Sean, and are very happy with the outcome of the installation of solar panels & batteries.”

Home Energy Scotland funds heat pumps up to £7,500 (£9,000 in remote rural, island and off-gas accessible rural areas) but not solar PV or battery storage: no HES grant or loan applies to batteries.
“My solar system sends energy to the grid, but I still pay for electricity at night.”
“I want to add batteries but don’t know where to start.”
“I’m worried I’ll choose the wrong system or overpay.”
Scotland’s solar curve and its electricity-use curve don’t line up, and that mismatch is the economic case for solar battery storage in Scotland.
Solar peaks at midday and your use peaks morning and evening, a gap your meter data can measure. Sean reads your half-hourly usage, existing or planned solar and tariff, then sizes the battery and its charging schedule to fit.
Power you would export at 4p/kWh runs your evening in place of 30p peak electricity.
On a time-of-use tariff the battery charges at around 8p/kWh overnight, with or without panels on the roof.
Where you want backup, we add an EPS or gateway so the circuits you choose keep running in a power cut.
Its LFP cells are rated for 6,000+ cycles, and it goes in at 0% VAT up to 31 March 2027.
Scroll one real day: the bank fills on sunshine and runs the house through the evening peak.
Overnight the house sipped from the bank. By dawn there is still charge in hand.
From mid-morning the array charges the bank while also running the house. Nothing bought.
A 20.8 kWh bank fills on a decent day before the school run gets home.
Four till seven is when electricity costs most. The house does not notice; it is on stored sun.
A battery moves your afternoon into your evening. Honest engineering, sized to how you actually live.

Carradale village hall on the remote west coast is prone to power cuts, so we fitted 30 panels, 48 kWh of Fox batteries and an automatic gateway. With air con left off, the backup is designed to run essential circuits for a couple of days.
Aventus Eco is an Official EcoFlow Partner, and PowerOcean is the battery we specify most for Scottish homes: modular, expandable, built on LFP cell chemistry with integrated fire prevention. Already have panels on the roof? A battery retrofit for your existing solar is usually a one-day job.

Illustration of a typical installation
Storing surplus solar for the evening is half of what a battery does here. In Scotland the bigger financial argument is what happens on a smart tariff.
If you have or are planning a heat pump installation, the battery buffers it: the pump runs on stored cheap electricity through peak hours instead of full-rate power.
Payback comes down to sizing and tariff strategy, not the badge on the wall.
Begin with how the capacity was chosen: the answer should quote your half-hourly usage and your tariff.
Illustration of a typical installation
Sean reviews your half-hourly usage data, existing or planned solar generation, current tariff, and property layout. You get a written design, not a sales quote.
Battery capacity, inverter compatibility, smart tariff strategy, and SEG export optimisation: all sized to your actual numbers, not a stock template.
Battery installations qualify for 0% VAT until March 2027. We explain the finance options that genuinely apply in 2026: no overpromising on grants that no longer exist.
1 to 2 day installs, MCS-certified from start to finish, a named engineer leading every job, dust sheets down throughout.
Live walkthrough of your monitoring app, smart tariff schedule setup, and a digital handover pack with everything you need for SEG sign-up and warranty registration.
Message your engineer directly. Controls set up and explained at handover, and ongoing access for as long as you own the system.
Christine’s family home in Gartcosh was paying around £600 some months, even with an air source heat pump already fitted.
“We’ve had very attentive customer service from Sean, and are very happy with the outcome of the installation of solar panels & batteries. We are also grateful for his knowledge and input into adjusting our heat pump and currently our bills are massively reduced. Being able to text Sean at any time to ask a question and get a helpful reply within a reasonable amount of time has been a very important aspect to me of the service before and after installation.”

Absolutely, most systems are battery-ready, and we can retrofit with minimal disruption.
Yes, even low solar generation can be stored and used efficiently with a well-sized setup.
We’ll analyse your usage and build a system that fits. No guesswork or overkill.
Yes, especially if you pair the battery with a smart tariff like Octopus Flux. Most installs pay back in 6 to 10 years on top of solar self-consumption savings. We model your specific payback during the survey.
Not always. On smart tariffs, a battery alone can deliver real savings by buying cheap overnight electricity and discharging at peak. Backup power and grid resilience are also valid standalone reasons.
Yes. You’ll get a direct contact, remote monitoring, and ongoing system health checks.
Solar battery cost in Scotland depends on capacity and whether it’s a standalone retrofit or a combined solar-plus-battery install. We give you an exact figure after survey, not a price-list guess.
A standalone battery retrofit in Scotland usually takes 1 to 2 days; a combined solar-plus-battery install runs 2 to 3 days. You get a clear schedule before we start.
Your energy system should work for years. And so should your installer.
A few details is all it takes. We reply within one working day, with a real engineer, not a call centre.
We’ll assess your setup, explain your options, and leave you to decide.
