This article contains affiliate links. We may earn a commission if you buy through our links, at no extra cost to you. Prices are from iHeat and Heatable’s own tools and pages, checked 25 August 2026, and change from time to time, so the live quote is the figure that counts. Last reviewed: August 2026.
If you’re pricing solar panels, the public floor to work from is iHeat’s catalogue, which starts at £4,295 for a small All Black array, or £6,145 once you add a battery. Heatable take a different route: draw your roof in their 3D tool and it returns a live cash price on the spot, built around LONGi’s Hi-MO X10 485W panels. Quote Heatable first for the design and a real number, then add iHeat if you want a published from-price or a named battery.
The catch is that a headline like £4,295 buys a modest array, scaffolding usually sits outside the online number, and there’s no Boiler Upgrade Scheme money for solar, that’s a heat pump grant, so our solar panel grants guide covers the help that does exist. If you’re weighing panels with storage, our solar and battery guide covers the sizing first.

The short version
The public floor for solar is iHeat’s catalogue, from £4,295 for a small All Black array (about £89 a month) and £6,145 with a battery. Heatable don’t publish a fixed list; instead their 3D tool prices your actual roof on the spot, around LONGi’s Hi-MO X10 485W panels with microinverters, which is the closest thing to a real quote without a visit. Both are MCS-certified. Quote Heatable first for a design and a live number, then use iHeat’s catalogue as your published second quote. Treat any headline as a starting point, since a bigger array and scaffolding both move it.
iHeat solar prices
iHeat publish a fixed catalogue, which makes them the easy place to see a public from-price. These are their listed prices including VAT, before any survey. The £4,295 entry is a small All Black array, so it’s a floor rather than a typical whole-roof system:
| Package | From (inc VAT) | Monthly from |
|---|---|---|
| Solar only | ||
| All Black 450W | £4,295 | £89 |
| LONGi 480W | £4,945 | £103 |
| Aiko Neostar 3S 475W | £4,995 | £104 |
| Solar and battery | ||
| All Black + Hanchu 3.7kWh | £6,145 | £128 |
| All Black + Duracell 5kWh | £6,645 | £138 |
| All Black + Sigenergy 6kWh | £7,845 | £163 |
| LONGi + Duracell 16kWh | £8,445 | £176 |
| All Black + Powerwall 3 13.5kWh | £9,845 | £205 |
iHeat also list batteries on their own for a retrofit: a Hanchu 5kWh from £3,645 (about £76 a month), a Sigenergy 6kWh from £5,245 (about £109) and a Tesla Powerwall 3 from £7,945 (about £166). There’s no battery-only Duracell option, so Duracell only comes as part of a solar bundle. On finance, iHeat’s solar plans start from 9.9% APR Representative Fixed, so it isn’t 0%. They’re MCS-certified and a Which? Trusted Trader, with a Trustpilot score of 4.8 from more than 10,000 reviews.
Heatable solar prices
Heatable price your roof rather than a shelf. You draw your property in their 3D design tool and it returns a live cash price for your home, built around LONGi’s Hi-MO X10 485W panels with microinverters (their MCS registration is NAP-68602). Because the figure is tied to your actual roof, it’s the closest thing to a real quote without a visit.
The prices logged in the tool on the evening of 20 August had an Alpha battery bundle at £5,690, a Sigenergy 9.04kWh at £6,100 and a Tesla Powerwall 3 at £7,595, but those are a snapshot rather than today’s number, so open the tool for your own figure. Two things to factor in: scaffolding is charged on top, typically £500 to £750, and Heatable’s “pay nothing ’til 2027” line is the 0% VAT relief that runs to 31 March 2027, not interest-free finance. Their Trustpilot score is 4.8 from more than 14,000 reviews.
VAT and grants on solar
There’s no Boiler Upgrade Scheme money for solar; that grant is for heat pumps, so ignore anyone implying a solar equivalent. What you do get is 0% VAT on qualifying residential solar and battery installs until 31 March 2027, after which it returns to 5%. That relief is exactly what Heatable’s “pay nothing ’til 2027” refers to, and it applies to panels and to a battery. Some English households may also qualify for the Warm Homes: Local Grant, which can include solar, so it’s worth checking your eligibility before you buy.
What pushes the price up
The catalogue floor and the 3D-tool starting price both assume a straightforward job. These are what move the number:
- Array size. £4,295 buys a small All Black array. A bigger roof or more output means more panels, and more cost.
- Scaffolding. Most installs need it, and it’s usually charged on top, typically £500 to £750.
- Adding a battery. Storage steps the price up sharply, as the bundle rows show, from £6,145 with a small battery to £9,845 with a Powerwall 3.
- Roof and electrics. A complex or awkward roof, or work to the consumer unit, adds to the job.
A live price and a published floor
Both installers are MCS-certified. Heatable price your actual roof in their 3D tool, which is the quickest route to a real number. iHeat publish a fixed catalogue, so they’re the easy second quote and the place to compare named batteries. Start with Heatable.
- LONGi Hi-MO X10 485W with microinverters
- Prices your actual roof, no visit needed
- Scaffolding extra, typically £500 to £750
- MCS registered (NAP-68602)
- All Black, LONGi and Aiko panels
- Named batteries from Hanchu to Powerwall 3
- Solar finance from 9.9% APR Rep. Fixed
- MCS + Which? Trusted Trader
Who solar is for
Solar makes most sense if you have a decent, reasonably unshaded roof and you’re either home enough during the day to use what you generate, or you add a battery to store it for the evening. If you want a real price for your actual roof without a salesperson in the room, Heatable’s 3D tool is the quickest route. If you’d rather compare published from-prices and named batteries side by side, iHeat’s catalogue lays them out.
If you’re mainly after storage, iHeat also list batteries on their own for a retrofit, and it’s worth working out whether panels plus a battery pays off for your home and usage before you commit. Whichever way you go, take the headline as a floor and let the quote confirm the price for your roof.
Frequently asked questions about solar panel cost
How much do solar panels cost in the UK?
iHeat’s catalogue starts at £4,295 for a small All Black array, rising through £4,945 for LONGi and £4,995 for Aiko panels, all including VAT. Heatable price your actual roof in their 3D tool rather than publishing a fixed list. Scaffolding, typically £500 to £750, usually sits on top of the headline.
Is there a grant for solar panels?
There’s no Boiler Upgrade Scheme money for solar; that grant is for heat pumps. You do get 0% VAT on qualifying solar and battery installs until 31 March 2027, after which it rises to 5%. The Warm Homes: Local Grant can also include solar for qualifying households in England.
How much do solar panels with a battery cost?
On iHeat’s catalogue, solar-and-battery bundles run from £6,145 for an All Black array with a Hanchu 3.7kWh battery up to £9,845 for an All Black array with a Tesla Powerwall 3. The battery you choose and its size are what drive the difference.
Can I get 0% finance on solar panels?
iHeat’s solar finance starts from 9.9% APR Representative Fixed, so it isn’t 0%. Heatable’s “pay nothing ’til 2027” is the 0% VAT relief that runs to 31 March 2027, not interest-free credit, so read the two as separate things and check what applies on your quote.
What solar panels do Heatable and iHeat use?
Heatable fit LONGi’s Hi-MO X10 485W panels with microinverters. iHeat’s range includes an All Black 450W panel, a LONGi 480W and an Aiko Neostar 3S 475W, so you can pick on price or output.
Do I need scaffolding, and is it included?
Most solar installs need scaffolding. Heatable charge it on top of the tool price, typically £500 to £750, so factor it into any headline figure you see rather than assuming it’s included.
