Check My EligibilityWhat happens when solar VAT returns in 2027?
The 0% VAT rate on domestic solar installations was introduced in the Finance Act 2022 and is currently set to end March 2027. Three scenarios: SCENARIO 1 — VAT EXTENDED AT 0% (best case): No impact. Government may extend due to net zero commitments. Probability: 40-50%. SCENARIO 2 — VAT RETURNS TO 5% (likely): A 4kW system at £7,000 net → £7,350. Extra cost: £350. Impact on payback: +3-5 months. Probability: 30-40%. SCENARIO 3 — VAT RETURNS TO 20% (worst case): £7,000 net → £8,400. Extra cost: £1,400. Impact on payback: +1.5-2 years. Probability: 10-20%. RUSH EFFECT: Before any deadline, demand surges 30-50% (we saw this with FIT closure in 2019). This causes: wait times increase to 8-16 weeks, prices rise 5-10% due to demand. RECOMMENDATION: Install by December 2026 to guarantee 0% VAT AND avoid the rush. Order by October 2026 to guarantee pre-deadline installation.

Solar panels are most powerful when combined with an efficient heating system. Heat pumps use solar-generated electricity to heat your home at 300-400% efficiency — making them the ideal partner for solar.
Heat pump installation typically takes 2-3 days and is best planned alongside solar.
Solar panels and heat pumps together form the foundation of a net-zero home.
