Esdec Solar Mounting Systems UK - ClickFit Evo and FlatFix Fusion Explained
If you are looking for Esdec solar mounting systems in the UK, the two names you are most likely to compare are ClickFit Evo and FlatFix Fusion. In simple terms, ClickFit Evo is the installer-focused Esdec system for pitched and metal roof applications, while FlatFix Fusion is designed for flat roof solar projects. Both are built to make installation more straightforward, more consistent and easier to scale across real-world residential and commercial jobs.
That matters because the mounting system affects far more than how quickly the array goes on the roof. It also affects the finish of the install, the long-term stability of the system, compatibility with the roof type, and how easy it is to source the right accessories around the job.
At LAMPS, you can explore the wider solar mounting systems range, browse the dedicated Esdec Solar Mounting Systems UK page, or jump straight into the main application areas for flat roofs, corrugated roofs, standing seam roofs and trapezoidal roofs.
What Is Esdec?
Esdec is a solar mounting brand focused on roof-mounted PV systems. The main attraction for installers is that the systems are designed to reduce on-site complexity without turning the mounting side of the job into a custom fabrication exercise. Instead of piecing together a generic framework, installers can work within a defined system that is built around the roof type and panel layout.
For most UK projects, that means choosing between:
- ClickFit Evo for pitched roofs and a range of metal roof applications
- FlatFix Fusion for flat roof arrays where a non-penetrative system is often preferred
The wider appeal is consistency. Installers want mounting systems that are easier to specify, easier to repeat across projects and easier to support after the job is finished. That is why Esdec continues to be a common name in UK solar mounting discussions.

Why Solar Mounting Systems Matter More Than Many Buyers Realise
A solar array is only as strong as the system holding it in place. The panels and inverter usually get most of the attention, but the mounting system determines how the array sits on the roof, how the load is distributed, how the wiring is managed and how clean the finished install looks.
For installers, the right mounting system can also affect labour time, repeatability and the amount of guesswork needed on site. For end customers, it affects long-term confidence in the job. That is why roof type matters so much when choosing the system. A flat roof project needs a different approach from a tiled domestic roof or a standing seam metal roof.
In practice, this is why ClickFit Evo and FlatFix Fusion are best understood as two different routes rather than competing products for the exact same job.

ClickFit Evo vs FlatFix Fusion: Quick Comparison
| System | Best suited to | Typical strengths | Best starting point |
|---|---|---|---|
| ClickFit Evo | Pitched roofs and selected metal roof types | Fast-fit rails, roof-specific brackets and clamps, cleaner repeat installs | Esdec Solar Mounting Systems UK |
| FlatFix Fusion | Flat roofs | Non-penetrative layout, aerodynamic design, ballast-based approach | Flat roof systems |
ClickFit Evo: The Esdec System for Pitched Roofs and Metal Roof Projects
ClickFit Evo is the Esdec system most installers will look at for pitched-roof work and for several metal roof applications. The appeal is in the name: the system is built around a more efficient fitment method than older, more fragmented mounting approaches.
That does not mean one universal bracket for every roof. It means the same wider system logic can be applied across multiple roof types using purpose-built fixings and accessories. This is especially useful for installers who want a more consistent way of working across tiled, corrugated, standing seam and trapezoidal jobs.
Where ClickFit Evo makes the most sense
- Tiled roof projects where you want a recognisable rail-and-clamp system with defined compatible parts
- Corrugated roof jobs using roof-appropriate brackets and profiles
- Standing seam roofs where dedicated seam clamps are needed
- Trapezoidal roof installations using the right profiles, hanger bolts and fixings
Common ClickFit Evo components available from LAMPS
- ClickFit Evo Mounting Rail 2338mm
- ClickFit Evo Landscape Metal Roof Profile
- ClickFit Evo Hanger Bolt M10x200mm
- ClickFit Evo Double Folded Seam Clamp 9mm
- ClickFit Evo Round Seam Clamp 23mm
- ClickFit Evo Universal Module Clamp
- ClickFit Evo Rail Coupler
Why installers like ClickFit Evo
Installers usually choose ClickFit Evo because it offers a more repeatable system across multiple roof types. The parts are designed to work together, the roof-type options are clearer than in generic mounting approaches, and the rail-and-clamp logic is familiar enough to use efficiently on site.
It is also helpful that the wider Esdec and LAMPS material around the system is geared towards installer use rather than only homeowner-facing marketing. That makes ClickFit Evo especially relevant for trade buyers comparing complete mounting routes rather than one-off parts.

FlatFix Fusion: The Esdec System for Flat Roof Solar
FlatFix Fusion is Esdec’s flat-roof mounting route. For installers, the main attraction is that it is built specifically for flat roof solar rather than adapted from a pitched-roof rail concept. That matters because flat roofs create different design priorities, especially around roof penetrations, ballast, airflow and layout.
FlatFix Fusion is most relevant where you want a non-penetrative or low-disruption flat-roof mounting approach that still feels like a complete system rather than a collection of loosely related parts. This makes it a common starting point for residential flat roofs, commercial roofs and other projects where roof membrane integrity and repeatability are important.
Core FlatFix Fusion components available from LAMPS
- FlatFix Fusion Low Base
- FlatFix Fusion High Base
- FlatFix Fusion Base Profile 1077mm
- FlatFix Fusion Ballast Container 1700

- FlatFix Fusion Rear Wind Deflector 1700mm
- FlatFix Fusion Left Wind Deflector
- FlatFix Fusion Right Wind Deflector
- FlatFix Fusion MLPE Clip
- FlatFix Fusion Mat for TPO/PVC Roofs
Why FlatFix Fusion appeals to installers
FlatFix Fusion is attractive because it is designed around the real constraints of flat roofs. The system logic is modular, the parts are clearly defined, and the broader design is built around airflow, ballast and roof protection rather than simply fixing rails to a level surface.
That makes it a better fit for installers who want a more complete flat-roof system and a cleaner procurement route for the accessories that sit around it. It also helps with consistency across larger jobs, where repeating the same system logic matters even more.

Which Esdec System Should You Choose?
The simplest way to choose is to start with the roof.
Choose ClickFit Evo if:
- the project is on a pitched roof
- you are working on corrugated, standing seam or trapezoidal metal roofs
- you want a rail-and-clamp system with dedicated roof-specific fixings
- you need a consistent installer route across multiple pitched-roof job types
Choose FlatFix Fusion if:
- the project is on a flat roof
- you want a non-penetrative, ballast-based system approach
- you need components built specifically for flat-roof airflow and stability
- you want a clearly structured flat-roof ecosystem rather than adapting another system
That is really the key point. ClickFit Evo and FlatFix Fusion are not alternatives for the same job. They are different Esdec routes for different roof conditions.

Why Buy Esdec from LAMPS?
For trade buyers, the real advantage is not just access to Esdec parts. It is being able to source a broader section of the system and the surrounding solar products in one place. LAMPS supports that with Esdec category pages, individual product pages and the wider ranges around solar panels, solar inverters, solar cabling and optimisers and meters.
That makes LAMPS useful for installers who want a more practical procurement route rather than buying the mounting system in isolation. It also makes internal linking cleaner for the site, because the Esdec article can connect naturally to the broader solar categories and to the specific components installers are likely to search for.
