Planning a new build or extension is the perfect opportunity to future-proof your home. If you’re wondering whether you can add solar for a new build or extension, the answer is yes and it’s often easier and more cost-effective than retrofitting later on. By factoring solar into your project from the start, you can design an energy-efficient home that’s ready for the future.
Why Plan Solar with a New Build or Extension?
When building from scratch or extending your property, everything is up for consideration. That includes roof layout, electrical setup and energy goals. Installing solar panels during construction gives you more flexibility. You can tailor the system to help reduce your energy bills or lower your carbon footprint.
For example, you can design the roof pitch and orientation to maximise solar gain. You’ll also have access to the internal wiring and distribution boards before plastering or decoration takes place. This makes the installation neater, less disruptive and often more affordable.
A Smart Time to Go Solar
If you’re doing a self-build, there’s even more reason to consider solar from day one. You’re already making decisions about heating systems, insulation, smart home tech and energy use, so it makes sense to include solar in those conversations. Planning ahead can also make you eligible for certain building regulations and energy performance targets.

Our Solar Panel Systems for New Builds
At West Coast Electrical, we use high-quality Tier 1 solar panels from brands like Dmeg, Solfit and Aiko, paired with leading inverters and battery storage such as AlphaESS, Enphase and Tesla Powerwall. For mounting systems, we choose trusted names like Esdec, Fastensol, Schletter,and Van der Valk – ensuring each system is secure, compliant and long-lasting.
Whether you want a simple solar setup or a fully integrated system with battery storage and EV charger compatibility, we’ll tailor it to suit your build.
Integrate Battery Storage from the Start
Many homeowners now choose to install battery storage alongside solar, even if the battery comes later. During a new build or extension, we can prepare the system for future expansion. That includes installing cables, distribution boards and isolators in advance, so when you’re ready to add a battery, it’s a quick and tidy process.
Key Benefits of Adding Solar During a Build
• Cleaner install – We hide all wiring and fixings within the fabric of the building for a cleaner finish.
• Cost-effective – less labour and fewer materials needed when planned early.
• More options – roof layout, cable routes and equipment positions are flexible.
• Better performance – We optimise your system for solar gain and load usage to ensure better performance.
• Future-ready – ready for battery storage, EV charging and energy monitoring.
What About Planning Permission or Building Regulations?
If you’re adding solar panels to a new build or extension, you’ll be glad to know that in most cases, you won’t need planning permission. The rules classify solar panels as a ‘permitted development’ if they meet certain criteria – like not sticking out too far from the roof or being used on a listed building. That said, building regulations still apply, especially when connecting the system to your home’s electrical setup. At West Coast Electrical, we make sure every installation meets the latest safety and compliance standards, so you can move forward with confidence.
Is It Worth Adding Solar for a New Build or Extension?
Absolutely, solar is one of the best upgrades you can make during a build. Not only does it reduce your reliance on the grid, but it also helps protect against rising energy prices. While solar performance varies by property, adding it early makes the most of your investment.
It’s important to note that solar performance depends on multiple factors including roof angle, shading, location and how much energy your household uses. Every project is different, which is why we offer bespoke system design and advice tailored to your needs.
Every home and system design is different. Solar generation and savings will depend on your location, system size, usage patterns and export arrangements.
Plan Ahead with West Coast Electrical
We regularly work with builders, architects and developers to ensure solar is smoothly integrated into the construction process. Whether you’re at the early planning stage or already breaking ground, we’ll guide you through the best options and ensure everything is installed to current MCS standards.
