Battery Storage FAQs
Common questions about home battery storage — from choosing the right system and standalone batteries to backup power, costs, and existing GivEnergy support.
Are solar batteries worth it in Scotland without solar panels?
Sometimes. It depends heavily on your tariff. Without solar, a battery only saves money by charging when electricity is cheap and powering your home when it’s dearer, and some energy is lost on the way in and out. Home Energy Scotland notes that batteries don’t always recoup their cost. There is no Home Energy Scotland grant or loan for standalone batteries, so we look at your usage and tariff before recommending one.
Which home battery system is best for Scottish homes?
The best battery depends on your usage, solar setup, backup-power needs, budget, and the manufacturer support available at the time of quote. Tesla Powerwall 3 remains a strong premium option for customers wanting high output, whole-home backup options, and a polished app ecosystem. For other homes, a modular battery from another supported manufacturer may be a better fit.
Can I get a battery without having solar panels?
Yes. A standalone battery charges from the grid when electricity is cheaper and powers your home when it’s dearer. Installed standalone batteries currently carry 0% VAT. Whether it pays depends on your tariff and when you use electricity, so we look at both before recommending one.
What happens during a power cut?
Battery systems designed with backup capability can keep selected essential circuits running during a power cut. Backup needs to be specified during the design stage because not every battery installation includes it.
How long does a home battery last?
Home Energy Scotland says batteries tend to last between 10 and 15 years. Manufacturer warranties vary by brand and product, so we'll explain the warranty terms available at the time of quote. JME's own workmanship warranty is separate and covers defects caused by our installation work for six years from completion.
How big is a battery and where does it go?
Home batteries are wall-mounted or floor-standing units, and some are heavy: Tesla Powerwall 3 is 1105 × 609 × 193 mm and weighs 130 kg. Where one can go is decided at the survey. The fire-safety standard for home batteries, PAS 63100:2024, puts batteries outdoors where practicable. An indoor location needs fresh-air ventilation to outside and fire-resisting separation, and the standard rules out places such as bedrooms, escape-route landings, stairs and corridors, and lofts.
Can I add more battery capacity later on?
Often, yes, but it depends on the battery. Some systems can be expanded with extra units or modules; others can't. Where future expansion matters to you, we make it part of choosing the battery rather than assuming it can be upgraded later.
