Tell us about your home
Four short steps. Nothing is shared until you press send, and every question except your name, email and postcode is optional.
What happens after you send it
We reply by email
This site is not an installer and does not visit your home.
Each should give you a written, itemised quote
Ask for the usable capacity in kWh, the inverter power in kW, what backup is included, the warranty terms and the full installed price.
You check the prices before anything else
Put each price into the quote checker and read the comparison checklist. There is no obligation to accept any quote.
Have these ready
An installer can only price a battery properly with a few facts about your home. Having them to hand makes the first conversation shorter and the quotes more comparable.
- Your yearly electricity use in kWh, from a bill or your supplier's app. With a smart meter, the half-hourly figures show how much you use after dark, which is what sizes the battery.
- If you already have solar: the MCS certificate and the inverter's make and model. Octopus, for example, asks for both before fitting a battery to panels it did not install, because the network application needs the inverter's details. Feed-in Tariff customers may need to tell their FIT provider.
- Where a battery could go: an outside wall, a garage or a utility room. Bedrooms, hallways, landings and lofts are ruled out under PAS 63100.
- Photos of your fuse box and meter. Some installers survey remotely from photos and a form before deciding whether a visit is needed.
- Your plans: an electric car, a heat pump or a tariff change all change the right size.
What the process usually looks like
- A survey, remote or in person, to confirm the location, the cable route and your consumer unit.
- A written quote naming the battery, its usable kWh, the inverter, any backup equipment and the warranties.
- Network approval. Small systems are notified to the network operator after installation under G98; larger ones need a G99 application first, which can add weeks.
- Installation day. For a Tesla Powerwall, Tesla says a typical installation takes a full day with the power off for about four to six hours.
- Paperwork: an electrical installation certificate with a PAS 63100 statement, an MCS certificate and the warranty registration.
Your request goes only to the publisher, who replies by email. The privacy notice explains exactly who receives it.
Why the form asks what it asks
Only your name, email and postcode are required. Every other answer is optional, and each one changes what an installer can price, so a fuller form gets a more useful first reply.
- What you are looking for. The four choices are different jobs: panels and a battery fitted together under one hybrid inverter, a battery added to panels you already have (usually an AC-coupled retrofit), a battery without solar charged on an off-peak or half-hourly tariff, or not sure yet, which tells installers to talk it through with you.
- Type of home and yearly use. A flat or a terraced house limits where a battery can go under PAS 63100, and the kWh figure on your bill is what sizes the battery. If you are unsure, pick the closest band; an installer you hire will check against your meter data.
- Electric car, heat pump and backup. A car or a heat pump adds evening and overnight demand that a larger battery can serve, and backup adds hardware and cost, so these three tick boxes change both the size and the price of a quote.
- Postcode. The full postcode, such as LS6 4QR. It decides which network operator and regional tariffs apply to your home, and lets an installer check the property.
- Ownership, timing and payment. A landlord or a tenant needs different permissions from an owner, "just researching" tells installers not to book a survey yet, and paying by savings or by finance changes the shape of the quote.
- Phone and the message box. Phone is optional and only for people who would rather be called. The most useful line to put in the message box is what you already have, for example "existing 4kW solar from 2019", because that tells an installer to price a retrofit and check your inverter.
What a fair price looks like before the quotes arrive
It helps to know the normal range before the first figure lands. The official median installed prices for MCS-certified batteries in 2025/26, with a band 20% either side, give these totals for the three most common sizes:
| Usable size | Official median | Typical range | Lowest published package |
|---|---|---|---|
| 5 kWh | £6,500 | £5,200 to £7,800 | from £3,947 (Octopus, battery only) |
| 10 kWh | £8,900 | £7,120 to £10,680 | from £5,336 (Octopus, battery only) |
| 13.5 kWh | £8,505 | £6,804 to £10,206 | from £7,999 (Octopus, Tesla Powerwall 3) |
An energy supplier's standard package usually sits below the range; an independent installer's quote inside it is normal. A quote above it is not necessarily wrong, since backup equipment, a consumer unit upgrade or fire-rated work can all add cost, but each extra should be itemised. The quote checker does this comparison for any price and size.
