Why Install Solar Panels?
Greater Energy
Independence
Producing energy from solar PV panels reduces your reliance on the grid. Many of our systems give you power cut protection.
Earn Money
Sell excess energy generated back to the national grid and you'll get paid the Smart Export Guarantee (SEG) by your solar panel company, reducing your electricity bills.
Shrink Your Carbon
Footprint
Generating your own solar power makes a positive impact on the environment by reducing the amount of fossil fuels used to power your home.
Boosted Home
Value
Having solar panels installed can increase the value of your home by making it more energy-efficient and attractive to prospective buyers interested in reducing their energy costs.

Planning a complete solar panel system?
If you're considering buying an electric car or are thinking about adding solar batteries, we can include an EV Charger and battery storage in our solar solution. Future proofing your system.
Many homeowners exploring solar panel installation for their home ask about battery storage and it is a question worth considering carefully. A solar panel system often generates more electricity than you use during daylight hours. Without storage, that surplus is exported to the grid through the Smart Export Guarantee. Useful, but typically less valuable than using it yourself.
Adding battery storage allows you to capture daytime generation for evening use, overnight consumption, or power cut protection. As certified Tesla Powerwall and GivEnergy installers, we specify storage where it genuinely improves the financial case and we will model both scenarios during your consultation so you can compare the options clearly.
Solar Panel Installation Cost: What to Expect
Solar panel installation costs in the UK vary primarily by system size, roof complexity, and whether battery storage is included. Here are typical price ranges for domestic solar panel installation:
| System Size | Typical Cost (Exc. VAT) | With Battery Storage |
|---|---|---|
| 4kW | £5,000 – £8,000 | £9,000 – £14,000 |
| 5kW | £6,000 – £9,000 | £10,000 – £15,000 |
| 6kW | £8,000 – £13,000 | £12,000 – £18,000 |
| 8kW | £12,000 – £18,000 | £16,000 – £23,000 |
| 10kW | £16,000 – £22,000 | £20,000 – £28,000 |
These figures reflect what homeowners typically pay, including installation and 0% VAT. Your actual quote depends on factors a price table cannot capture: how many people are in your household, your energy usage, when you're home and any high energy purchases you are considering — for example an electric vehicle or hot tub.
These details shape which system genuinely suits you, which is precisely what our free whole-house energy assessment is designed to establish. We review your bills, discuss your routines, and model the scenarios that fit your life, so the system we recommend is sized around how you actually live, not an industry average.
Solar Panel Funding and Incentives
Installing solar panels is a great way to reduce your energy bills. Up until April 2019 the Feed-in Tariff scheme (FITs) paid you for every unit of electricity you generated. Today, there are still ways you can implement renewable energy solutions while still earning money from your installation.
Do I need planning permission to install solar panels?
In most cases, solar panels mounted on a roof or wall of a private house do not need planning permission as they would normally fall under permitted development rights. However, certain types of properties are more likely to require planning permission for solar panel installations, including: Listed Buildings, Flats and Properties in Conservation Areas
Working in partnership with local architects we offer Solar Planning Assistance. They work with us to design your system and liaise with the local planning authority on your behalf.
