Terms of Using Solar Panel Cost Calculator
These terms of use are the agreement between you and the publisher of Solar Panel Cost Calculator for using its calculators, its estimates and its survey request route. They apply when you use any page at solarpanelcostcalculator.uk, starting with the calculator these terms cover. By using the site you agree to them. Nothing in them takes away your rights under UK consumer law.
Version 1.0.
Who We Are and How These Terms Work
The site is run by Solar Panel Cost Calculator Ltd, a private limited company registered in England and Wales, company number 16928471, registered office 20 Wenlock Road, London, N1 7GU, United Kingdom. Our contact email is [email protected]. These terms, our privacy policy and our cookie policy together govern your use of the site. If a court finds one clause unenforceable, the other clauses still apply.
What This Site Is, and What It Is Not
We publish solar cost, savings and payback estimates for UK homes; we do not sell, fit or finance solar panels or batteries. Those figures are estimates, never quotes or advice, and the detail is in our disclaimer.
| We are not | What that means for you |
|---|---|
| An installer | We never fit panels or batteries. Installers give the quote. |
| MCS or MCS-certified | MCS registration belongs to each installer. We hold no certification. |
| A lender or credit broker | We do not arrange credit or recommend a lender. Finance an installer offers after a survey is between you and that installer. |
| The government or a government scheme | We do not run, assess or award any grant or scheme. |
| An energy supplier | We do not sell electricity or export tariffs. |
| An installer vetting service | We do not inspect installers. MCS registration is the installer's own certification. |
Calculators and estimates cost you nothing to use.
Our Estimates Are Not Quotes, Offers or Advice
Every figure on this site is an estimate worked out from your answers and from public data with a stated date; it is not a quote, an offer, a survey or financial advice.
A real price can differ because of your roof, scaffolding, wiring, the installer's own prices and your exact usage. Data has dates, and some rules change on known dates. VAT on home solar panels and batteries is 0% until 31 March 2027 and 5% from 1 April 2027 (HM Revenue and Customs, VAT Notice 708/6). The Ofgem price cap changes every quarter, and the rate we use is the one for 1 October to 31 December 2026. Each figure carries a source and the date we checked it, and the log is our page of sources and data dates.
Check scheme, tax and tariff rules with the official source before you rely on them. Do not make a financial decision on an estimate alone: get written quotes from MCS-registered installers. Our Good fit, Borderline and Poor fit verdict is an estimate of fit, not a promise of savings.
Asking for a Survey Through Leads 2 Trade
You will get phone calls. That is how surveys are arranged.
The survey request form on this site is not open yet, so we pass nobody's details to Leads 2 Trade Limited today. These are the conditions we plan for a survey request once the form opens:
- You meet the survey criteria: you own the home the request is about, and the home is in the UK.
- You submit only your own name, phone number and email address.
- We do not pass on a request marked "Just researching".
- We do not offer a survey on a Poor fit verdict or to tenants. A tenant can share the estimate with the landlord.
- We may decline to pass on a request from outside the areas installers cover, or one that looks false.
- You pay nothing for the survey.
We are paid by Leads 2 Trade Limited when a homeowner we refer asks for a survey. You are never charged. It does not change our figures. More on this is on our page about how we earn from survey requests.
Your details go to Leads 2 Trade only with your consent. What each company then holds, and how to withdraw, is in our policy on how we use and share your information.
Your Contract Is With the Installer, Not With Us
Any contract to survey, supply or fit solar panels, a battery or anything else is between you and the installer you choose; we are not a party to it, which means we have no rights or duties under it. We do not recommend, endorse or guarantee any installer or product. MCS registration is the installer's own certification. The quote, the price, the workmanship, the warranty and any finance on offer are the installer's responsibility. If something goes wrong, raise it with the installer first, then with MCS.
Using the Site Fairly
You may use the site and its calculators for your own home, and to help a friend or relative with their permission. These uses are not allowed:
- submitting someone else's details, or false details, in the survey form;
- using automated tools to run the calculators at volume or to copy the site (the calculators run in your browser, and automated scraping, or traffic that overloads the site, is not allowed);
- trying to get around a security check on the site;
- interfering with the site or its servers;
- using the site to send spam or unlawful content;
- presenting our estimates as your own quotes, or as a quote from us;
- implying that we endorse you or your business.
If you break these rules, we may block your access and, if a survey request was false, ask Leads 2 Trade to delete it.

Our Responsibility to You, and Its Limits
We take care to keep our figures accurate and dated, but we cannot promise every figure is right for your home at the moment you read it.
- Nothing in these terms limits or excludes our liability, which means our legal responsibility, for death or personal injury caused by our negligence, for fraud, or for anything else the law does not allow us to limit.
- If you are a consumer, a person using the site outside a trade or business, you keep your statutory rights, the rights the law gives you whatever a contract says.
- We are not responsible for losses that were not foreseeable, for decisions you make about buying or financing a system, or for the acts of Leads 2 Trade or any installer. Each of those companies is responsible for its own acts.
- The site is provided as it is, and it may sometimes be unavailable for maintenance or for reasons outside our control.
- If you use the site for a business: the site is made for UK homeowners using it for their own homes, so any business use is at your own judgement.
If you find an error, tell us and we will check it against the source and date the fix.
Links to Other Websites
We link to other websites, such as gov.uk, Ofgem, MCS and Leads 2 Trade, so you can check sources; we are not responsible for their content. A link is not an endorsement.
Changes to These Terms
When we change these terms we publish the new version here with its date and version number, and we keep earlier versions. A change applies from the date shown, and not to anything that happened before that date. A change that would affect a survey request you have already made does not apply to that request. This is version 1.0.
Which Law Applies
The law that governs these terms, and the courts that can hear a dispute about them, are: the law of England and Wales and the courts of England and Wales, but if you are a consumer living in Scotland or Northern Ireland, you may also bring a claim in the courts where you live.
Contact Us About These Terms
Questions about these terms go to [email protected], and we reply within 2 working days. A correction, a data request and a complaint each have their own route, listed on our contact page.
