What does a solar panel installer do, and what does it cost in the UK?
A solar panel installer designs, fits and commissions a roof-mounted PV array — typically a 4kW system with 14 panels. UK 2026 cost: £4,000–£10,000 depending on size, with battery storage adding £2,000–£4,500. MCS certification is mandatory for SEG export payments and 0% VAT (until March 2027). Payback is typically 7–12 years.

Savings & Payback Period
A typical 4kW system saves £500–£900 per year on electricity bills. Smart Export Guarantee (SEG) payments: 4–15p per kWh exported. Payback period: 7–12 years depending on usage, export payments and electricity prices. With battery storage, self-consumption rises from ~50% to 70–80%, improving savings.
Government Incentives
Smart Export Guarantee (SEG): mandatory offer from energy suppliers, paying 4–15p/kWh for exported electricity. 0% VAT on solar installations until March 2027. Boiler Upgrade Scheme: up to £7,500 for heat pumps (pairs well with solar). No feed-in tariff for new installations, but SEG payments are growing.
MCS Certification
All solar panel installations must be done by an MCS-certified installer to qualify for SEG payments and government incentives. MCS certification ensures the installation meets quality and safety standards. All solar panel installers on TradeMatch are MCS-certified.
Solar panel installer vs general electrician vs roofer
| Job | Solar installer | Electrician | Roofer |
|---|---|---|---|
| RECOMMENDEDRoof-mounted PV system | ✅ Recommended | ❌ Not MCS | ❌ Not electrical |
| Battery storage | ✅ Yes | ⚠️ Specialist only | ❌ Not electrical |
| SEG export claim | ✅ Standard | ❌ Not eligible | ❌ Not eligible |
| Roof prep / tile cut-out | ✅ Yes | ❌ No | ✅ Yes |
| EV-charger pairing | ✅ Often | ✅ Yes | ❌ No |
Always use an MCS-certified installer for solar. Without MCS you cannot claim SEG payments or 0% VAT, which makes the system 20% more expensive over its life.
