What’s the Solar Panel Installation Process Like in the UK?
Thinking about solar but not sure what the install process actually involves?
Here’s the good news: for most UK homes, solar panel installation is fast, straightforward, and managed entirely by your installer. In many cases, panels are up and running within a day or two.
This guide breaks down each step of the journey so you know exactly what to expect.
Step 1: Free Assessment & Feasibility Check
Before anything is installed, your home will be assessed to make sure solar is a good fit.
Installers typically use aerial maps, software, or photos of your roof to check:
Orientation (south-facing isn’t essential)
Shading risks from trees or chimneys
Roof size and available space
Your electricity usage and goals
Some systems can be quoted without a visit. If your setup is more complex or includes batteries, the installer may book a quick site survey.
Step 2: Formal Quotation
You’ll receive a clear, itemised quote that includes:
Solar panels and inverter
Optional extras like batteries or EV chargers
Scaffolding and labour
MCS certification
Estimated annual savings and payback period
Trusted UK installers will also provide equipment datasheets, workmanship warranties, and expected installation timelines.
Step 3: Site Visit & Technical Survey (if needed)
Some homes may need a quick visit to:
Check the condition of your roof
Review the best cable route to your consumer unit
Ensure your fuse board has space for the system
Confirm access for scaffolding
This helps avoid surprises and ensures a safe, compliant install.
Step 4: Scaffolding Setup
A scaffolding team will usually arrive the day before or morning of installation. This ensures safe access to your roof and gives the solar team a clean, efficient workspace.
Step 5: Installation Day
The solar team will arrive with all equipment and begin installing:
Roof anchors and rails
Solar panels
Cabling through to your inverter
The inverter and isolators (often placed near the fuse board or in a utility area)
Most standard systems are installed within 1–2 days.
Step 6: Electrical Connection & Commissioning
Once mounted, the system is connected to your home’s electrical system by a qualified electrician. They’ll:
Wire the system into your consumer unit
Perform electrical safety tests
Power up and confirm everything is working
Set up any monitoring apps for you
Step 7: Handover Pack & Certification
You’ll receive a full handover pack including:
MCS certificate (needed for export payments and future property sales)
Datasheets and warranty documents
Instructions for using your system
Contact details for future support
Step 8: DNO Notification & Export Setup
Your installer will notify your local DNO (Distribution Network Operator) so your system can legally export to the grid.
They’ll also explain how to apply for the Smart Export Guarantee (SEG) to get paid for any excess energy you export.

Will It Disrupt My Home?
Very little. Most UK homeowners can stay in their homes throughout. Electricity may be off for 1–2 hours during final connection. Installers will clean up before leaving and explain how to use your new system.
What If I Need a Battery or EV Charger?
These can often be installed at the same time. Some homes may need extra cabling or switchgear, which your installer will highlight in your quote.
