Tell us about your property and existing solar setup. We assess your compatibility, call you back the same day, and arrange a no-obligation survey. You receive a written quote with an exact price.
What happens after you submit
We review your details and assess your existing solar system, inverter type and postcode to determine which battery retrofit path applies to your property. A member of our team calls you back — usually the same day — to discuss your options.
If your system is compatible, we arrange a no-obligation survey at your home. The surveyor confirms your wiring, inverter model, available space for the battery, and whether G98 or G99 applies based on your DNO area. After the survey, you receive a written no-obligation quote with an exact price, the recommended battery brand and the installation timeline.
Why your postcode matters for the quote
Your postcode tells us which DNO area you are in — SP Energy Networks for central and southern Scotland including Glasgow and Edinburgh, or SSEN for the north, Highlands and Islands including Aberdeen. This determines whether your battery needs G98 notification or G99 prior approval, which affects the timeline. Your postcode also helps us estimate local solar yield ranges per MCS MIS 3002, so we can give you a realistic picture of what a battery will store across the seasons.
What we need from you
The quote form asks for your name, email, phone, postcode and property type. If you know your inverter brand and approximate install year, mention them when we call — this helps us assess compatibility faster. If you do not know, that is fine; the surveyor will check during the site visit.
Knowing whether you have a string inverter, hybrid inverter, or microinverter system is the single most useful piece of information. If you can read the brand name on the inverter unit (usually mounted on a wall or in a loft), that helps us narrow down the retrofit path before the survey.
How the quote compares to a typical installation
A 10kWh retrofit battery on existing solar typically costs ~£4,900–£5,100 installed. If a new hybrid inverter is needed, expect £6,000–£8,000+. A 5kWh battery starts at ~£3,500–£4,500 (homeenergyquotes.co.uk, Aug 2026; checked October 2026). Your written quote gives you an exact price based on your actual system and property — no estimate ranges.

Battery storage and 0% VAT
Battery storage installed with retrofit solar qualifies for 0% VAT until 31 March 2027 in the UK. Standalone batteries may also qualify — we confirm this during your survey. After March 2027, the rate may revert to 5% or 20% depending on government policy at the time.
Timeline from quote to installation
After you submit the form, we call you back the same day during business hours. The no-obligation survey is typically arranged within one to two weeks. If G99 prior approval is needed, DNO approval takes 4 to 8 weeks. The installation itself takes one to two days on site. The full timeline from quote to commissioned battery is typically 6 to 12 weeks, depending on DNO approval times and installer availability in your area.
