A smart time to go solar in South Wales
Grid prices remain high and 0% VAT makes new systems cheaper than they have been in years. Here is why Cardiff homeowners are making the switch.
0% VAT until March 2027
The government has removed VAT on residential solar and battery installations — a 20% saving on the pre-2022 price. After March 2027 it rises to 5%.
Protection from rising bills
Generating your own electricity shields you from grid price rises, and the Smart Export Guarantee pays you for the surplus you send back.
Adds value to your home
Research from the Energy Saving Trust consistently shows solar-equipped homes attract more buyers and can sell for more than equivalent properties without solar.
