Solar Panel Quotes UK: The Complete 2026 Guide

Solar Panels Quotes UK 2026

Solar panel quotes in the UK are free and typically arrive within 24–48 hours of an online request. A 4kW system for a three-bedroom home costs between £6,500 and £8,500 installed in 2026. Homeowners should compare at least three quotes from MCS-certified installers, because prices for an identical system routinely vary by 20–40% between companies.

Quick Summary

What is a solar panel quote?

A solar panel quote is a written estimate from an installer setting out the system they propose for your specific property: the panel brand and count, the inverter type, total system size in kWp, projected annual output in kWh, and the fully installed price.

A quote is not the same as an online estimate. An estimate is generated from postcode and roof size assumptions. A quote is produced after an installer has assessed your actual roof — orientation, pitch, shading, electrical setup — and is the figure they are prepared to stand behind.

Where can I get solar panel quotes in the UK?

Comparison platforms

You submit your details once and receive quotes from multiple MCS-certified installers. Fastest route to a genuine comparison. Free to the homeowner — platforms are paid a referral fee by the installer on completed jobs, not by you.

Contacting installers directly.

Most control, most work. You research each company, verify accreditation yourself, and arrange each survey separately. Reasonable if you already know local installers by reputation.

General trades directories

Checkatrade, Which? Trusted Traders and similar list solar alongside dozens of other trades. Broad, but solar-specific verification tends to be a secondary feature rather than the core function.

SolarForYou sits in the first category and is built specifically for solar: MCS accreditation is verified before an installer is listed, you receive up to three quotes, and there is no charge and no obligation to proceed.

Choosing the right system size

What details do I need to get an accurate quote?

Have these ready before you request quotes. Supplying them upfront is the difference between a rough estimate and a quote that holds:

  • Postcode determines regional irradiance, installer availability and scaffold costs.
  • Annual electricity usage in kWh on any recent bill. This sizes the system correctly. Guessing here is the most common cause of an oversized quote.
  • Roof orientation and approximate pitch south-facing at 30–45° is optimal in the UK, but east–west splits work well with the right design.
  • Roof type and age slate, tile or metal; and whether it is likely to need work within ten years.
  • Shading chimneys, trees, neighbouring buildings.
  • Whether you want battery storage this changes the quote substantially and should be specified, not assumed.
  • When you are typically home daytime occupancy determines self-consumption rate, which drives the savings projection.

How many solar quotes should I get?

We recommend getting at least 3 solar quotes. One quote gives you no reference point. Two tells you which is cheaper but not whether either is reasonable. Three lets you identify the median and spot the outlier — which is the actual purpose of comparing.

Beyond three, returns fall away quickly. Most comparison platforms draw from an overlapping pool of accredited installers in any given region, so a fourth and fifth quote often means repeat contact from companies you have already heard from.

How do I compare solar panel quotes properly?

Compare on seven things, in this order:

  1. MCS accreditation verify independently at mcscertified.com/find-an-installer. Non-negotiable.
  2. Panel brand, model and warranty a named Tier 1 brand with a 25-year performance warranty. “Tier 1 panels” as a category is not an answer.
  3. Inverter type and warranty string, micro-inverter or optimiser, and why that choice suits your roof. 5-year warranty minimum.
  4. System size and projected annual kWh cross-check the output figure against PVGIS, which is free and independent.
  5. What is included scaffold, DNO notification, Part P certificate and consumer unit upgrades should be in the price, not added later.
  6. SEG eligibility confirmed in writing, not assumed.
  7. Aftercare workmanship warranty length, who to call for a fault, whether monitoring is included.

Why do quotes for the same system vary so much?

The variation is real and it is not random. It comes from panel and inverter tier, whether scaffold is included or billed separately, installer overhead, how far the crew has to travel, and how conservatively the installer has estimated your annual output.

This is precisely why a single quote is not enough information to act on. A price is only high or low relative to something.

How do I know an installer is trustworthy?

  • Current MCS certificate — check the number yourself, do not accept a logo on a PDF.
  • RECC or HIES consumer code membership.
  • Companies House record showing more than three years of trading.
  • Reviews that describe specific installations rather than generic praise.
  • No pressure to sign at the survey visit. A quote that expires in 24 hours is a sales tactic.
  • MCS accreditation, verified before listing

Frequently Asked Questions

Are solar panel quotes free in the UK?

Yes. Requesting and comparing solar quotes is free for homeowners. Comparison platforms are paid a referral fee by the installer when a job completes, and installers absorb survey costs as a cost of sale. If a platform asks you to pay to unlock quotes or to see installer contact details, that is not standard UK practice.

How long does it take to get a solar panel quote?

An initial quote based on your property details typically arrives within 24–48 hours. A firm quote usually follows a survey — either a remote satellite assessment or an in-person roof inspection — which is generally scheduled within one to two weeks. Peak demand in spring and early summer can extend this.

What is the average cost of installing solar panels in the UK?

A 4kW system, the standard choice for a three-bedroom home, costs £6,500 to £8,500 fully installed in 2026, including 0% VAT. Adding battery storage typically brings the total to £10,000–£14,000. Cost per kW falls as system size rises, so larger systems are better value per unit of capacity.

Do I have to accept a quote after requesting one?

No. Quotes are non-obligation. You can receive three quotes and decline all three. Before submitting details to any platform, check what happens if you do not respond — a reputable service will not pass your number to installers who then chase you repeatedly.

Can I get solar panel quotes with financing options?

Many MCS-certified installers offer finance, typically as an unsecured personal loan through a third-party lender or a buy-now-pay-later arrangement over 5–15 years. If finance matters to you, say so when requesting quotes — not every installer offers it, and the total repayable can differ significantly from the headline cash price.
