Solar Guide

Solar Panel Costs UK

What UK homeowners actually pay for solar in 2026 — and how to compare quotes accurately.

Solar panels are one of the most popular home energy upgrades in the UK, but pricing can be confusing. This guide walks through typical price ranges, what drives cost up or down, and how to get a fair quote for your home.

Typical UK solar panel prices

As a rough guide for 2026, fully installed systems often fall in these ranges:

  • 3 kW system: ~£5,000 – £7,000 (suits small homes / 1–2 people)
  • 4 kW system: ~£6,000 – £8,500 (suits typical 3-bed semi)
  • 5–6 kW system: ~£8,000 – £11,000 (suits larger homes / EV owners)
  • With battery: add roughly £3,000 – £6,000 depending on capacity

These are indicative only — the only way to know your actual cost is to request quotes for your specific roof.

What affects the price

  • Panel wattage and brand (Tier 1 brands cost more but often perform better long term)
  • Inverter type — string vs hybrid vs micro-inverters
  • Roof pitch, orientation and complexity
  • Scaffolding requirements and number of storeys
  • Whether you add battery storage
  • MCS certification and warranty length

VAT on solar in the UK

The UK government has zero-rated VAT on most residential solar installations until 31 March 2027. Confirm current VAT treatment with your installer when getting a quote.

How to get a fair price

Get at least two or three quotes so you can compare panel brands, warranty length and total cost. Watch out for very low quotes that use unbranded equipment, or very high quotes that bundle in items you didn't ask for.
