Direct MCS-Certified Solar Installer vs National Solar Sales Brokers (2026 Price Audit)
How do I avoid overpriced door-to-door solar quotes in the UK?
Fair 2026 UK trade-direct MCS pricing should never exceed £1,250 to £1,450 per kWp for solar panels plus £420 to £480 per kWh of LiFePO4 battery storage. Quotes above £10,500 for a 4kW system with a 5kWh battery almost always include £2,500 to £4,000 in lead-broker and salesperson commissions.

|---|---|---|
| Price per kWp (Solar Array + Inverter + Scaffold) | £1,180 – £1,380 / kWp | £2,100 – £2,800 / kWp |
| 5.1 kWh LiFePO4 Battery Add-On (0% VAT) | £2,150 – £2,450 | £3,800 – £5,200 |
