Solar roof tiles replace your existing roof covering and generate electricity at the same time, but they cost two to three times more than standard solar panels for a similar output. Most UK homeowners will get better value from traditional panels unless they're already replacing a roof or live in a conservation area. No grant currently covers solar roof tiles directly, though 0% VAT applies and the Smart Export Guarantee pays you for surplus electricity you export.
What Are Solar Roof Tiles and How Do They Differ from Panels?
Think of them as roof tiles that happen to be solar cells. Instead of bolting large panels onto your existing roof, you strip the old tiles off and replace them with photovoltaic tiles that look like slate, clay, or flat concrete.
The technology itself isn't new. Companies like Marley and Solarcentury have been making them for over a decade, and Tesla's Solar Roof got a lot of attention when it launched in the US, though UK availability has been patchy. More recently, brands like Mitrex and GB Sol have entered the UK market with tiles designed specifically for British roof profiles and weather conditions. The key difference from panels is integration: solar roof tiles sit flush with your roofline rather than protruding above it, which matters enormously if you live in a listed building or a conservation area where planning officers would reject conventional panels on sight.

But here's the trade-off most marketing glosses over.
Solar roof tiles are less efficient per square metre than standard panels. A typical solar panel in 2026 converts 20% to 22% of sunlight into electricity. Most solar roof tiles manage 15% to 18%. That means you need more roof area to generate the same output, and you're paying significantly more for each watt you install.
So why do people buy them? Three reasons: aesthetics, roof replacement timing, and planning restrictions. If any of those apply to you, keep reading. If none do, you'll almost certainly get better value from standard solar panels.
How Much Do Solar Roof Tiles Cost in the UK in 2026?
£10,000 to £25,000. That's the realistic range for a typical UK home.
The spread is enormous because the final price depends on your roof size, the tile brand, the complexity of the installation, and whether you're replacing the entire roof covering at the same time. A straightish terraced house with 25 square metres of south-facing roof will sit at the lower end. A detached property with a complex hip roof, dormers, and 50+ square metres will push toward the top.
Here's how that compares to conventional panels:
System type
Typical 4kW cost
Cost per kW
Efficiency
Standard solar panels
£5,000–£7,000
£1,250–£1,750
20%–22%
Solar roof tiles
£10,000–£18,000
£2,500–£4,500
15%–18%
Tesla Solar Roof (where available)
£18,000–£25,000
£4,500–£6,250
17%–19%
Those panel costs come from current MCS installer data and Energy Saving Trust estimates. Solar tile pricing is harder to pin down because fewer installers offer them and quotes vary wildly, but those ranges reflect what we've seen from UK-based installers quoting in early 2026.
One thing that softens the blow: 0% VAT applies to solar roof tiles just as it does to conventional panels, saving you roughly 20% on the supply and installation cost. On a £15,000 installation, that's £3,000 you're not paying. The VAT relief runs until 31 March 2027, though there's talk of an extension.
And if you're already budgeting for a full roof replacement (which can cost £5,000 to £12,000 on its own for a standard re-tile), the incremental cost of going solar starts to look more reasonable. You're not paying for a roof plus panels. You're paying for a roof that is the panels.
Can You Get a Grant to Help Pay for Solar Roof Tiles?
Honestly, this is where the news gets thin.
No current UK grant scheme specifically funds solar roof tiles for most homeowners. ECO4 can fund solar panels for eligible low-income households, but the installations we see through that scheme use standard panels, not tiles. The Boiler Upgrade Scheme covers heat pumps, not solar of any kind. The Great British Insulation Scheme closed in March 2026 and never covered solar anyway.
What you do get:
0% VAT on the full installation, which is automatic. Your installer simply doesn't charge VAT on a domestic solar installation. No forms, no application. If your installer charges you 20% VAT on a domestic solar tile installation, challenge it.
The Smart Export Guarantee pays you for surplus electricity you send back to the grid. Rates vary by supplier. Octopus Energy currently pays around 15p per kWh on their Agile export tariff. British Gas offers about 12p. Some smaller suppliers pay as little as 3p. We've covered the full picture in our solar panel grants guide, and the same export payments apply regardless of whether your system uses panels or tiles.
The Warm Homes: Local Grant is worth checking too. It's a local-authority-run scheme that funds energy efficiency measures for lower-income households, and some councils have discretion over which technologies they support. We haven't seen solar tiles funded through it yet, but the scheme is open until December 2028 and eligibility varies by area.
Which Homes Are Suitable for Solar Roof Tiles?
Not every roof works. And that's true for standard panels too, but solar tiles are pickier.
You need a south-facing or south-east/south-west roof with minimal shading. That part is the same as any solar installation. But solar tiles also need a roof that's due for replacement or at least one you're willing to strip back to the battens, because installation involves removing your existing covering entirely. You can't just bolt tiles on top of what's already there.
Roof pitch matters. Most solar tiles are designed for pitches between 20° and 60°. Flat roofs are out. Very steep roofs above 60° reduce output and complicate installation.
Conservation areas and listed buildings are where solar tiles genuinely shine. If your local planning authority has rejected a standard panel application on aesthetic grounds, solar tiles that mimic slate or clay may get approval where panels wouldn't. Check with your council's planning department before committing, but this is the single strongest argument for choosing tiles over panels.
Right, one thing people don't think about: structural load. Solar tiles weigh roughly the same as conventional roof tiles (sometimes slightly more, sometimes slightly less depending on the brand), so most roofs can handle them without reinforcement. Standard solar panels, by contrast, add weight on top of your existing tiles. If your roof structure is borderline, tiles might actually be the lighter option overall. Worth getting a structural survey either way.
Your EPC rating will improve after installation, which matters if you're a landlord or planning to sell. Solar generation typically bumps a home up one to two bands.
Solar Roof Tiles vs Traditional Solar Panels: Which Saves More?
Panels. Almost every time.
Let's run the numbers on a typical 4kW system. A standard panel installation costs around £6,000 and generates roughly 3,400 kWh per year in southern England (less in Scotland, more in the south-west). At current electricity prices of around 24.5p per kWh, that's about £830 a year in avoided electricity costs, plus whatever you earn from the Smart Export Guarantee on surplus.
A solar tile system generating the same 3,400 kWh costs £12,000 to £18,000. Same output. Same savings. Double to triple the upfront cost.
The payback period tells the story:
System
Installed cost
Annual saving
Simple payback
4kW solar panels
£6,000
~£830
~7 years
4kW solar tiles
£14,000
~£830
~17 years
4kW tiles (with roof replacement offset)
£8,000 net
~£830
~10 years
That last row is the important one. If you're already spending £6,000 on a new roof, the net additional cost of going solar with tiles drops dramatically, and the payback period starts looking reasonable.
So here's our honest take: if your roof is in good condition and you have no planning restrictions, standard solar panels are almost always the better investment. The savings are identical, the cost is far lower, and modern panels last 25 to 30 years with minimal maintenance.
But if you need a new roof anyway, or you live somewhere that won't allow panels, or you genuinely can't stand the look of them, then solar tiles become a legitimate option rather than a vanity project.
Adding battery storage improves the economics of either system by letting you store daytime generation for evening use, but the battery cost (£3,000 to £6,000) is the same regardless of whether you use panels or tiles. It doesn't change the relative comparison.
How to Find a Trusted Solar Roof Tile Installer in the UK
This is genuinely harder than finding a panel installer.
The MCS certification scheme covers solar roof tiles, so start there. Any installer fitting solar tiles should be MCS-certified, and the installation must be MCS-registered for you to qualify for the Smart Export Guarantee payments. Without MCS certification, you lose the export income.
The problem is that far fewer installers work with solar tiles than with panels. Most solar companies in the UK fit panels exclusively. You'll likely need a specialist, and that limits your options and your ability to get competitive quotes.
Get at least three quotes. We know that's harder when there are fewer installers, but the price variation we see on solar tile quotes is even wider than for panels. One installer might quote £12,000 for a job another quotes £18,000. The product, the labour model, and the margin all vary enormously in a market this young.
Ask every installer these questions:
Are you MCS-certified for solar tile installations specifically?
Which tile brand do you install, and what's the product warranty?
What's the total warranted output degradation over 25 years?
Does your quote include scaffolding, removal of existing tiles, and disposal?
Will the installation be notified to building control?
Here's what most guides won't tell you: the roof tile warranty and the solar warranty are sometimes separate. You might get a 25-year warranty on the solar cells but only a 10-year warranty on the tile's weatherproofing. Check both. A solar tile that leaks after 12 years is a very expensive problem.
If you're exploring solar alongside other energy upgrades, it's worth checking your EPC first to see which improvements give you the biggest bang for your money. Sometimes loft insulation or better glazing should come before solar, tiles or otherwise.

Frequently asked questions
Do solar roof tiles work in the UK climate?
Yes. Solar roof tiles work on the same photovoltaic technology as standard panels and generate electricity from daylight, not direct sunshine. A 4kW solar tile system in central England will produce roughly 3,200 to 3,600 kWh per year. Output drops in winter and on overcast days, but the UK gets enough annual irradiance for solar to be worthwhile. Scotland generates about 10% to 15% less than the south of England, but it's still a viable return on a system that lasts 25+ years.
Do you need planning permission for solar roof tiles?
Usually not. Solar roof tiles fall under permitted development rights for most homes in England and Wales, the same as standard panels. The big exception is listed buildings, where you'll need listed building consent. Conservation areas are where tiles have an advantage: councils that reject standard panels on visual grounds may approve tiles that mimic traditional slate or clay. Always check with your local planning authority before committing.
How long do solar roof tiles last?
Most manufacturers warranty the solar output for 25 years, with guaranteed output of at least 80% of original capacity at that point. The tile itself as a weatherproof roof covering should last 40 to 50 years, similar to conventional concrete or slate tiles. But check both warranties separately, because they're not always the same length.
Can you add a battery to a solar roof tile system?
Yes, and you probably should. A battery lets you store electricity generated during the day and use it in the evening when rates are highest. The battery itself costs £3,000 to £6,000 depending on capacity, and it connects to the inverter the same way it would with standard panels. There's no technical difference on the battery side.
Are Tesla Solar Roof tiles available in the UK?
Barely. Tesla has taken UK orders intermittently but installations have been extremely limited. As of early 2026, most UK homeowners looking at solar tiles will be choosing between brands like Marley, GB Sol, or Mitrex rather than Tesla. If Tesla UK availability matters to you, join their waitlist, but don't plan your roof replacement around it.
