How much do solar roof tiles cost in the UK?
SolarTyle's current comparison is much closer to premium conventional in-roof solar than older solar roof tile figures may suggest.
Short answer
As at August 2026, a typical 4 kWp SolarTyle rooftop solar installation is approximately £6,000. A comparable premium conventional in-roof solar system is approximately £5,000 on the same stated basis.
These are SolarTyle's indicative single-dwelling comparison figures, not a project or whole-roof quotation. System size, roof design, access, electrical requirements, project scale and agreed scope can change the final price.
| System | Approximate 4 kWp cost | Approximate cost per kWp |
|---|---|---|
| Premium conventional in-roof solar | £5,000 | £1,250/kWp |
| SolarTyle solar roof tiles | £6,000 | £1,500/kWp |
Why do some websites still quote around £12,000?
Energy Saving Trust gives a market estimate of around £12,000 for a typical 4 kWp solar roof tile installation, with prices stated as accurate in November 2025. It also states that removing existing tiles and scaffolding are excluded.
That benchmark should not automatically be treated as the current price of every solar roof tile product. Product, date and installation scope can differ. SolarTyle's current indicative comparison is approximately £6,000 for the rooftop solar installation described above.

What has changed at SolarTyle?
SolarTyle has increased UK stockholding, developed its UK assembly and distribution operation and designed the product around compatible UK roofing materials and established installation methods. This supports a more repeatable supply route than importing small quantities for individual projects.
The current price comparison reflects SolarTyle's August 2026 commercial position. Every project still requires a scoped quotation.
The right comparison depends on the roof project
New build or development
Design the solar area, surrounding roof tiles and electrical interfaces before procurement. Repeatable layouts, existing site access and multi-plot supply can change the cost per property.
SolarTyle costs and design for new buildsPlanned roof replacement
Compare the incremental solar cost with the roof renewal already required. Scaffolding, stripping, underlay and battens may already form part of the roofing project.
Installing solar when a roof needs replacingExisting sound roof
SolarTyle forms part of the roof covering. If the existing roof has a long service life remaining and the only aim is to add solar, conventional bolt-on or in-roof solar may be more economical.
Compare solar tiles and panelsWhy the complete roof can change the comparison
The solar component is only one part of a new-build or re-roof budget. SolarTyle is designed to work with selected thin-leading-edge concrete roof tiles, so a project may compare that combined specification with premium clay or natural slate plus separate in-roof solar.
SolarTyle's illustrative 200 m² schedule shows why the whole roof should be reviewed. These are internal comparison assumptions, not general market rates or guaranteed savings.
| Roof and solar specification | Illustrative roof covering | Illustrative solar | Combined cost |
|---|---|---|---|
| Thin-leading-edge concrete tile plus SolarTyle | £18,000 | £6,000 | £24,000 |
| Red clay tile plus conventional in-roof solar | £24,000 | £5,000 | £29,000 |
| Natural slate plus conventional in-roof solar | £30,000 | £5,000 | £35,000 |
Actual material and installation costs vary with roof design, product specification, labour, access, location and project requirements. Request a project-specific comparison before changing a roof specification.

Compare predicted generation as well as installed capacity
Two systems rated at 4 kWp can have different predicted annual generation. Orientation, shading, pitch and how effectively modules use the available roof all affect expected output.
Use our guides to understand why two 4 kWp systems can produce differently, how roof orientation changes solar generation and why module format matters on complex roofs.
What the headline comparison does and does not mean
| Item | How to treat it |
|---|---|
| Rooftop solar system | Included in the indicative comparison at the stated capacity |
| VAT | Confirm the treatment in the project quotation |
| Inverter and electrical connection | Confirm equipment, cable routes and electrical scope |
| Scaffolding and access | Price for the actual property or development |
| Roof stripping and waste | Relevant to a re-roof, not automatically part of the solar comparison |
| Underlay, battens and non-solar tiles | Price within the complete roof package where required |
| Battery storage | Optional separate equipment unless expressly included |
Product evidence behind the comparison
- SolarTyle data-sheet module power: up to 95 W.
- SolarTyle data-sheet module efficiency: up to 22.5% under the stated test conditions.
- Actual generation depends on roof orientation, pitch, shading, layout, weather and system design.
Solar roof tile cost questions
Is £6,000 a whole-roof quotation?
No. It is SolarTyle's indicative comparison for a typical 4 kWp rooftop solar installation on a single dwelling. The complete roof and project scope must be quoted separately.
Why compare SolarTyle with premium in-roof solar?
Both are integrated into the roof plane. That is a more useful rooftop-solar comparison than comparing SolarTyle only with the lowest-cost bolt-on panel system.
Can SolarTyle be fitted over an existing completed roof?
No. SolarTyle is designed as part of the roof covering. It is best considered during a new build, extension, planned roof replacement or major refurbishment.
Does the price include a battery?
Do not assume battery storage is included. Specify and price it separately where required.
Is every SolarTyle system exactly £1,500 per kWp?
No. The figure is an indicative comparison. Module count, layout, access, electrical design, project scale and installation scope affect the project price.
