Questions, answered.

No. Solar saves you money when the sun’s out. A Juicy battery saves you money every day of the year, including in January, because it buys electricity when it’s cheap rather than generating it. No roof work, no scaffolding, no planning permission. If you already have solar, we work alongside it.

Electricity costs different amounts through the day. Overnight it can be a third of the daytime rate. Your battery fills up in the cheap hours and runs your home through the expensive ones, so you’re buying the same electricity at a much lower price. Your usage doesn’t change. What you pay for it does.

Usually a garage, a utility room, or a sheltered spot on an external wall. Following current UK safety guidance we don’t install in lofts or under stairs. You show us your preferred spot during the remote survey and we confirm it meets fire safety regulations and our installation requirements. Full specifications for every size, including dimensions and weight, are at juicy.energy/specs.

Yes. We only use Lithium Iron Phosphate (LFP) batteries, a more stable chemistry than the batteries in phones and laptops and the standard choice for home storage. Every system has a battery management system monitoring temperature and condition continuously, and we monitor remotely too.

Not as standard. Backup power is not included: it needs extra equipment and changes the installation, so it is designed and quoted after the technical survey. Tell us during your quote if it matters to you.

The 5 kW inverter has no fan and is cooled passively. It runs below 30 dB, quieter than a fridge. Most customers put it in a garage or utility room and never notice it. Full specifications for every size, including dimensions and weight, are at juicy.energy/specs.

The battery and inverter carry our 10-year warranty. If either develops a fault, you claim from us and we repair or replace the part at no cost; you never have to deal with the manufacturer. That warranty ends if you leave the arrangement early or keep the battery at the full price after cancelling, though the manufacturer warranties carry on. Our installation work has its own 24-month workmanship warranty. The cells are rated for 8,000 cycles and we cycle the battery about once a day. Lithium Iron Phosphate cells degrade slowly, so expect the battery to still be doing useful work well beyond ten years, with reduced capacity. Full specifications for every size, including dimensions and weight, are at juicy.energy/specs.

£440 to £1,141 a year, depending on how much electricity you use: a smaller home using about 225 kWh a month saves around £440 with either battery; a family home using about 342 kWh a month saves around £668 with either battery; a large home using about 583 kWh a month saves around £750 with the 10 kWh or £1,141 with the 16 kWh. Your figure depends on how much electricity you use, when you use it and which tariff you’re on, which is why we ask for your latest bill before quoting rather than guessing. Full specifications for every size, including dimensions and weight, are at juicy.energy/specs.Assumptions. Without Juicy assumes the Jul '26 price cap of 26p/kWh. With Juicy assumes a smart tariff at 9p/kWh off-peak and 32p/kWh peak, with the battery charging overnight and running the home through the day. Prices held flat; no solar. Your quote uses your own bill.

Typically five to seven years. On the best time-of-use tariffs it can be closer to four. Your quote shows your own payback figure, calculated from your bill rather than an average.

No. At least ten years of optimisation software, maintenance and monitoring are included in the price you pay up front. There is no monthly fee, ever, for as long as we manage the battery.

Because your battery earns money helping to balance the national grid, and we pass that value to you as a discount up front. The full explanation is on our homepage. Full specifications for every size, including dimensions and weight, are at juicy.energy/specs.

Any export payments from your supplier are yours. We don’t take a share.

The £299 is your first payment towards the price. It pays for the technical survey and design work we do as soon as you order, so we can confirm the install and get any network operator application in. If you cancel before we have started that work, you get it back in full. If you cancel while it is under way, you pay for the work done and we refund the rest within 14 days. Once the survey and design are complete, the deposit has been earned and we keep it if you then decide not to go ahead, but you owe nothing more. You get it back in full if we cannot go ahead: if your home fails the survey, the network operator says no, extra work is needed and you decline it, or we have not installed within 6 months for reasons that are not down to you.

Three payments, all by card or bank transfer through Stripe. The £299 deposit when you order. Then 40% of the remaining balance when we confirm your installation date. Then the rest before work starts on installation day; we send the link when we confirm your date and remind you the working day before. The last payment needs to have cleared before our engineer begins. Any extra work agreed after the survey is paid with the 40% payment unless its quote says otherwise. There is no VAT on the battery or its installation.

For each year of the 120 months we manage your battery, we guarantee you save at least a tenth of what you paid for the battery and standard installation. We measure the saving from our own records of what the battery did and your tariff rates, not from your bills, and it includes any solar energy the battery stored and fed into your home. Within 60 days of the end of each year we send you a statement. If your saving is short, the statement shows the difference and you claim it by email or in the Juicy app within 90 days. You do not need to send any evidence, and we pay by bank transfer within 30 days of your claim. If you have not claimed after 60 days we remind you. An unclaimed shortfall does not disappear: it carries forward to your next statement and stays claimable until the arrangement ends. Two things need to be in place. First, you are on the tariff we recommended to you in writing before installation, or one we have confirmed as suitable; if you change tariff, tell us within 30 days and we confirm within 10 working days whether the new one counts. Second, your home is in use: days when the house uses under 3 kWh are left out once you have had 21 of them in a year, so holidays are fine but an empty home is not. The guarantee does not cover days you are on a tariff we have not confirmed, days beyond those 21 when the house is empty, or days the controller has been offline for more than a week because of something on your side. On those days the guaranteed amount is reduced in proportion. It is a guarantee of savings from the battery, not of your total bill: standing charges and what you use are still yours. If you leave early, the final part year is measured in proportion and any shortfall is taken off your early-exit repayment.

You own the battery from day one. Juicy manages when it charges and discharges for at least ten years, then month to month until either of us ends it on 30 days’ notice. It’s a condition of your savings guarantee, because we can only guarantee savings we deliver ourselves, and it’s how we earn the grid revenue that funds your discount. Like a boiler guarantee that’s conditional on annual servicing, except we do the servicing every second, remotely, and you never book anything.

You repay part of the discount you received, in proportion to the months left of the 120. Leave after 30 months and you repay 90 months’ worth; after month 120 there is nothing to repay. You never repay anything if you leave because we have broken the contract and not fixed it, or because we stop providing the service. Our own 10-year warranty ends if you leave early; the manufacturer warranties carry on. Your quote shows the exact figure in pounds before you commit, so you know the cost of leaving before you start. After year ten the agreement runs month to month with 30 days’ notice and nothing to repay.

Three options. Pass the arrangement to the new owner: they sign our transfer form before you leave, the savings guarantee continues for them, and there is no clawback. Move the battery to another home you own: no clawback, you cover the reasonable cost of moving it, and the new home needs to pass our checks. Or end the arrangement, and the early-exit repayment applies.

You do, from day one. We don’t own it, lease it to you, or hold any rights over your property.

You own the battery, so it stays yours and keeps working. If we, or anyone who takes over from us, stop providing the service for good, there is nothing to repay, you keep the manufacturer warranties, you can run the battery yourself through the inverter’s app or ask another provider to, and anything we owe you is still payable. If a replacement operator takes over the service instead, the arrangement carries on with them. That’s the most important protection and it’s built into how the deal is structured rather than promised.

You don’t have to, but you’ll save considerably more on a time-of-use tariff. We recommend a tariff in writing before we commission your battery. You make the switch with your supplier and keep your own supplier. There is nothing to do on the tariff side until your install date is booked.

No. Every day we commit to moving 80% of your battery’s usable capacity from your cheap window into your peak hours. It is capped at what you use at peak and at what the battery can physically charge in your cheap window, because we cannot shift more than that. If we miss it on a normal day, we pay you the shortfall at your peak rate, without you having to claim. On days the battery works for the grid, a separate promise takes over: if that work raises your bill in a month, we pay you the difference. The whole model depends on your bill going down.

Usually 2 to 3 weeks for the 10 kWh system, which only needs a notification to your network operator. The 16 kWh, 20 kWh and 32 kWh systems need the network operator’s approval first, commonly 4 to 8 weeks, occasionally longer, and that wait is outside our control. We make the application for you. The installation itself is one day either way. Full specifications for every size, including dimensions and weight, are at juicy.energy/specs.

Yes, for the day. Someone over 18 needs to be there to let the engineers in and take the handover walkthrough at the end.

No. Floors covered, overshoes on, all waste and packaging taken away. There’s a full walkthrough of installation day on our how it works page.

No scaffolding. Batteries go on a wall inside or on the outside of your home, with no roof work. Home batteries do not normally need planning permission; if your home is listed or in a conservation area, check, because any consent that applies is yours to get.

The £299 deposit comes first, when you order. It pays for the technical survey and design work we do next. If that survey finds extra work is needed, we quote it in writing before anything else happens. You can go ahead, or walk away and we refund everything you have paid, including the deposit, within 14 days. Once we accept your order your price is locked and we never add costs on the day. The only exception is if your own delay pushes installation more than 60 days past acceptance, when we may re-quote.

We install nationwide across England, Scotland and Wales.

Juicy Energy Group Limited, a UK company installing and managing home batteries. We’re not an energy supplier and we don’t replace yours.

Yes. Our engineers are fully insured and every installation comes with a 24-month workmanship warranty.
