Frequently Asked Questions
How long does it take to install a solar system?
Installation typically takes 1-2 days, but the full process from quote to activation takes 4-8 weeks due to planning, DNO applications, and inspections.
Do I need planning permission for solar panels?
Most residential solar installations are permitted development and don't need planning permission. Listed buildings and conservation areas may have restrictions.
Will solar panels work on cloudy days?
Yes, solar panels generate electricity even on cloudy days, though at reduced efficiency. The UK receives enough sunlight to make solar viable.
Can I get grants for solar panels?
While there's no direct grant for solar panels, you benefit from 0% VAT (saving £1,000-£2,000) and may qualify for ECO4 if eligible.
Can I combine different grants and schemes?
Yes, you can typically combine the Boiler Upgrade Scheme with 0% VAT and ECO4 support if eligible.
What happens if I move house?
Owned systems typically increase home value and transfer to the new owner. Any remaining finance stays with you unless specifically arranged otherwise.
How much roof space do I need for solar?
A typical 4kW system needs about 25 square metres of unshaded, south-facing roof space. East and west-facing roofs also work well.
Do heat pumps work in cold weather?
Modern heat pumps work efficiently down to -15°C. They're suitable for most UK homes with proper insulation.
What size heat pump do I need?
This depends on your home's heat loss. A qualified installer will perform a heat loss calculation to determine the correct size.
Ready to Start Your Green Energy Journey?
The UK's transition to green energy is supported by generous government incentives, making renewable energy more affordable than ever. With the Boiler Upgrade Scheme, 0% VAT, and various financing options, homeowners can significantly reduce both their energy bills and carbon footprint.
For most homes, we recommend:
- ✓ Start with efficiency improvements - insulation and draught-proofing first
- ✓ Install solar panels - take advantage of 0% VAT until 2027
- ✓ Add a heat pump - claim the £7,500 Boiler Upgrade Scheme grant
- ✓ Consider battery storage - maximize your solar investment
