Comparisun Terms of Use

Key points

• Comparisun ("we", "us", the "Platform") is operated by Luxa Energy LTD, Private company limited by shares, registered in Cyprus under HE 482253 (Registrar of Companies and Intellectual Property, Nicosia).
• Comparisun helps you compare solar installation offers. When you decide to buy, your contract for the system and installation is with the installer you choose — not with us — except when the seller is Luxa Energy, the installation business of our own group. In that case your contract is with Luxa Energy (see Section 3.2 for which company that is).
• Luxa Energy is one of the installers shown on Comparisun. We disclose how this affects ranking in Section 5 below and on our How Comparisun works page.
• Prices, savings, payback time, IRR and grant/subsidy amounts shown to you are estimates, not guarantees. Read "Estimates and financial figures" before you rely on any number.
• Submitting an order on Comparisun is a request for a site survey and a final quotation. You are not bound to buy anything until you go ahead by paying the installer's agreed initial payment (deposit or down payment) — see Section 3.1.
• You can create an account to save offers and track an order. You may be asked to upload documents (such as ID, utility bills or title deeds) as part of an order with an installer.
• This document explains what happens if Luxa Energy LTD changes ownership, how disputes are handled, and your rights as a consumer, including in Switzerland and the UK.

1. Who we are and what Comparisun is

Comparisun is a website operated by Luxa Energy LTD (Private company limited by shares), with its registered office at Chrysanthou Mylona 1, PANAYIDES BUILDING, 2nd floor, Flat/Office 1, 3030 Limassol, Cyprus, registered under HE 482253 with Registrar of Companies and Intellectual Property, Nicosia, VAT number CY60244887P. You can contact us at support@comparisun.net or support@comparisun.net, or by post at the address above.

Comparisun lets you enter information about your home and energy use, and shows you solar system offers so you can compare them side by side. Results shown to you come only from two sources: Luxa Energy's own packages, and installers who use the Raysly platform and have opted in to list their offers on Comparisun. We do not show hand-compiled or third-party offers that the installer itself has not supplied (see Section 5.4). We also provide an online calculator that estimates system size, cost, and potential savings based on the information you give us and third-party data sources (for example satellite and irradiance data).

Comparisun is a comparison and lead-generation service. It is not itself a seller of solar equipment or installation services, with one exception: Luxa Energy is an installation business affiliated with the operator of Comparisun, and its offers appear on Comparisun alongside offers from independent installers. Section 3 explains what that means for you.

Comparisun is offered in Cyprus, Switzerland, United Kingdom.

2. Accepting these Terms

By creating an account or submitting an order through Comparisun, you agree to these Terms of Use. We keep a record of that acceptance — which version of these Terms you accepted, and when — as evidence that you agreed; see our Privacy Notice for how that record is kept and for how long. Our Privacy Notice separately explains how we handle your personal data generally; it is information for you, not a contract you agree to. If you do not agree to these Terms, please do not use those features.

If you are a consumer in the European Union, the United Kingdom, or Switzerland, nothing in these Terms limits any right you have under mandatory consumer-protection law in your country of residence (see Section 13).

3. Who you contract with

3.1 General rule. Comparisun introduces you to installers. When you click "Submit order", you send the installer you selected (the "Installer") a request for a site survey and a final quotation. Submitting an order does not oblige you to buy. The Installer will give you its own terms and a final quotation before you are asked to go ahead. You accept the Installer's offer, and the purchase contract is formed, when you pay the Installer's agreed initial payment (a deposit or down payment) — by bank transfer or, where the Installer has enabled it, by card. Paying that initial payment is your go-ahead to the Installer to start work; until you pay it, you are free to walk away at no cost. The contract is formed between you and the Installer, on the Installer's own terms. Luxa Energy LTD is not a party to that contract and does not sell, install, warrant, or guarantee the solar system or installation, except as set out in 3.2.

Offer validity. A quotation generated by Comparisun or adjusted by the Installer is only valid for a limited period, set by the Installer and shown on the offer itself (typically 30 to 90 days). This validity period is shown per offer, not fixed in these Terms, because it is set individually by each Installer. After it expires, the Installer may need to requote before you can go ahead.

Withdrawing before you pay. Because no contract exists until you make the initial payment, you may withdraw your order, or simply not proceed, at any time before then, at no cost.

3.2 Exception — Luxa Energy. Luxa Energy is an installation business affiliated with Luxa Energy LTD (the operator of Comparisun). When you choose an offer from Luxa Energy, Luxa Energy is the seller and is directly responsible to you as the seller under applicable consumer law. Section 3.1 above (acceptance by paying the initial payment, and offer validity) applies equally to an Luxa Energy offer.

Today, Luxa Energy and Luxa Energy LTD are the same legal entity. Luxa Energy LTD is the seller for both the Comparisun comparison service and any order you place with Luxa Energy. If and once Luxa Energy becomes a separate company related to Luxa Energy LTD by common ownership (rather than the operator of Comparisun itself), your order contract will be with Luxa Energy directly, not with Luxa Energy LTD; Luxa Energy will be an independent seller responsible to you for that order, and Luxa Energy LTD's hand-off of your enquiry to Luxa Energy will be a disclosure to a separate business, on the same footing as any other installer that receives a lead through Raysly. The Privacy Notice (Section 6) and our How Comparisun works page (Section 5) describe this relationship in the same terms.

3.2a Your right to withdraw from an Luxa Energy contract. Once you have paid the initial payment and a contract exists, if you bought as a consumer and the contract was concluded at a distance or off-premises, you have a further statutory right to withdraw from it, in addition to the pre-payment withdrawal described in Section 3.1. In the European Union and the United Kingdom this is ordinarily a 14-day withdrawal period from the applicable starting point set by law. Luxa Energy will give you the withdrawal period, how it is calculated, the model withdrawal form, and what happens if you ask for work to start before the period ends, before you pay the initial payment and again in the confirmation.

3.3 Payment. Card payments are made through payment providers (currently Revolut, Mollie and Stripe) or by bank transfer directly to the Installer (or, for Luxa Energy orders, Luxa Energy). There is no separate Comparisun checkout or shop: a payment link or bank-transfer instruction is always provided by or on behalf of the Installer you are ordering from. Comparisun does not hold your payment card details.

4. Estimates and financial figures

4.1 What we show you. Comparisun shows estimated system size, estimated cost, estimated savings, estimated payback period, estimated internal rate of return (IRR), and, where available, estimated grant or subsidy amounts (together, the "Estimates"). Estimates are generated from the information you provide, publicly available or licensed third-party data (such as electricity tariffs, irradiance data, and government subsidy schedules), and modelling assumptions we choose.

4.2 Estimates are not guarantees, quotes, or financial advice. Actual system performance, cost, and savings depend on factors we cannot fully predict, including your actual electricity usage, weather, the final system design and site survey, installer pricing, and changes in tariffs, subsidies, or tax rules after the Estimate was generated. Estimates are not an offer, a quotation, or a promise of any particular outcome, and must not be relied upon as financial, tax, or investment advice. A final, binding quotation is only the one the Installer gives you directly before you sign a purchase agreement.

4.3 Grants and subsidies. Where we show a grant, subsidy, feed-in tariff, or tax-relief figure, that figure reflects a scheme we believe is currently in force and sourced from an official authority at the time shown. Subsidy schemes can close, change, or be oversubscribed at any time, including between the date you see the figure and the date you complete your purchase. We do not guarantee that any subsidy shown will still be available, or available in the amount shown, by the time you apply for it. If no verified figure is available for your region, we will show no figure rather than an estimate.

4.4 Limits of this disclaimer. This Section 4 explains that Estimates are not guarantees and are not a substitute for your own diligence and the Installer's final quotation. It does not, and is not intended to, exclude or limit our liability for our own negligence causing death or personal injury, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be excluded or limited under the law of your country of residence, including under the unfair-terms protections of Directive 93/13/EEC (as implemented in your country), the equivalent UK protections, or Article 8 of the Swiss Federal Act Against Unfair Competition (UWG). Where a term in this Section would otherwise be unfair or unenforceable under those laws, that term is limited to what the law allows, and the rest of this Section remains in force.

5. How we rank and compare offers

5.1 Ranking factors. Offers on Comparisun can be sorted by price, product quality/warranty, or "best value" (our default view, which combines estimated production per unit of price with a warranty-based quality score). The full, current description of how each sort works, including the factors we use and how they are weighted, is published on our How Comparisun works page and is linked from the results page. That page forms part of these Terms for the purposes of describing ranking; if it and this Section differ, that page prevails.

5.2 Luxa Energy's offers. Luxa Energy is one of the installers shown on Comparisun, alongside installers who use Raysly and have opted in to list their offers. Luxa Energy's offers are ranked using exactly the same criteria, weights and formula as every other installer's offers, with no bonus, adjustment or differentiated scoring of any kind for being affiliated with Luxa Energy LTD. Every Luxa Energy offer must carry a visible "Offer from the platform operator" label.

5.3 No paid placement. No installer, including Luxa Energy, pays for placement or improved ranking on Comparisun. Ranking is decided only by the criteria described in this Section and on our How Comparisun works page.

5.4 Independence of listed installers. Installers other than Luxa Energy are independent businesses who use the Raysly platform and have opted in to list their offers on Comparisun. We do not employ them.

• Installers who work with us supply their own product and price information through Raysly. We are not responsible for the accuracy of what they supply, but we take reasonable steps to keep it current.

5.5 If Luxa Energy is currently the only installer shown to you. As of this version, Luxa Energy is the only installer listed on Comparisun — no independent installer has yet opted in to list through Raysly. Currently, all offers shown to you are from Luxa Energy. We will show you offers from other installers as soon as they join and opt in to list. This does not change how Luxa Energy's offers are ranked (Section 5.2), and comparative language such as "compare offers" refers to comparing different system configurations and sort orders, not necessarily different installers, until more than one installer is listed.

6. Your account and saved offers

6.1 Creating an account. You may create an account using a magic link sent to your email, or another sign-in method we offer. You are responsible for keeping access to your email account secure, since it is used to verify your identity.

6.2 Saved offers. You can save an offer to revisit later or have it emailed to you. A saved offer is not an order and does not commit you or any Installer to anything.

6.3 Accuracy of your information. You are responsible for the accuracy of the information you give us (including your address, energy usage, and household details). Estimates and offers are only as accurate as the information you provide.

7. Uploads and documents

7.1 What we may ask you to upload. Depending on your country and the Installer's process, you may be asked to upload documents such as a photo ID or passport, recent electricity bills, proof of property ownership or a title deed, or other documents an Installer or authority requires to process your order (for example a grid-connection application or an energy performance certificate).

7.2 Why we collect these. We collect these documents on behalf of, and to pass to, the Installer processing your order (or, for Luxa Energy orders, for Luxa Energy's own use as the seller), because the Installer needs them to design, permit, and install your system, apply for any grant on your behalf, or meet its own regulatory obligations. Full detail on how these documents are processed, stored, and for how long, is in our Privacy Notice.

7.3 Your responsibility. You must only upload documents that are genuine, that belong to you or that you are authorised to submit, and that do not infringe anyone else's rights.

7.4 Uploading a competitor's offer. If you upload a solar offer you received from another company so we can help you compare it, you confirm you are entitled to share it with us. We remove certain personal details from those documents before using them (see the Privacy Notice for how this data is used, including in an anonymised market-data feed).

8. Acceptable use

You agree not to:

• use Comparisun to submit false, fraudulent, or someone else's personal information;
• attempt to interfere with, disrupt, reverse-engineer, or gain unauthorised access to Comparisun or its underlying systems;
• scrape, copy, or systematically extract offers, prices, or content from Comparisun for a competing product or service;
• use Comparisun to send unsolicited communications, malware, or unlawful content; or
• impersonate another person or misrepresent your affiliation with any person or company.

We may suspend or terminate your account if you materially breach this Section. Unless the breach is serious or urgent (for example fraud or a security risk), we will tell you why first and give you a chance to respond.

9. Intellectual property

Comparisun, its logo, design, software, and the content we publish (excluding content that belongs to Installers or other third parties) are owned by or licensed to Luxa Energy LTD. You may use Comparisun for your own personal, non-commercial purpose of comparing and purchasing a solar system. You may not reproduce, redistribute, or create derivative works from Comparisun's content except as these Terms permit.

10. Liability

10.1 What we are responsible for. We are responsible for operating Comparisun with reasonable skill and care, including preparing Estimates with reasonable care (Section 4), and, where Luxa Energy is the seller under Section 3.2, for its obligations as seller.

10.2 What we are not responsible for. Except where Luxa Energy is the seller under Section 3.2, we are not responsible for the acts or omissions of any Installer, including the quality of their products or workmanship, their pricing, their compliance with law, or their handling of your order or payment. Your remedies for a problem with the system or installation lie against the Installer, under the contract you formed with them and under the consumer-protection law that applies to that contract.

10.3 General limitation — the comparison and estimate service is free. Comparisun's comparison and estimate service does not charge you anything, and the Estimates it shows you are informational only (Section 4). Because of that:

(a) We are not liable for decisions you make based on the comparison service or an Estimate, or for an Installer's products, installation work or quotation — the Installer's own contract with you governs those matters — except where Luxa Energy is the seller under Section 3.2, in which case Luxa Energy's own contract with you (and its liability as seller) governs instead.

(b) For the free comparison and estimate service itself (excluding liability under Section 3.2 as seller), our liability is limited to loss caused intentionally or by our gross negligence.

(c) Nothing in this Section 10 excludes or limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be excluded or limited under the law of your country of residence, including under Directive 93/13/EEC (as implemented), the UK Consumer Rights Act 2015, Article 100(1) of the Swiss Code of Obligations (OR) and Article 8 of the Swiss Federal Act Against Unfair Competition (UWG), or under applicable product-liability law. This Section does not shorten any statutory limitation period that applies to your claim.

(d) We are not liable for indirect or consequential loss, to the extent this exclusion is permitted by the law of your country of residence.

If you are in the United Kingdom: any exclusion or limitation of our liability for negligence that causes loss other than death or personal injury is subject to the reasonableness and fairness test in the Consumer Rights Act 2015 (sections 62 and 65) and, where applicable, the Unfair Contract Terms Act 1977.

11. Changes to these Terms

We may update these Terms from time to time, for example to reflect a change in our services, in the law, or in who operates Comparisun. If a change is material, we will give you at least 30 days' notice before it takes effect, by posting a notice on Comparisun and, where we hold your email address, by email. Your continued use of Comparisun after a change takes effect means you accept the updated Terms; if you do not agree, you should stop using Comparisun and, if applicable, close your account. This does not affect your statutory right to end a contract you already have with an Installer or with Luxa Energy as seller.

12. Change of operator, sale, or restructuring (assignment and successor clause)

12.1 Our right to transfer. We may transfer, assign, or novate our rights and obligations under these Terms, in whole or in part, to another company in connection with a merger, acquisition, corporate reorganisation, or sale of all or substantially all of the business or assets to which these Terms relate (a "Business Transfer"), including a transfer of the operator of Comparisun from Luxa Energy LTD to a different group company or a new owner.

12.2 What this means for you as a consumer. If we make a Business Transfer:

• the new operator will continue to provide Comparisun on terms that are the same as, or no less favourable to you than, these Terms, until it gives you proper notice of any change (see Section 11);
• your existing rights against us for anything that happened before the transfer are not affected;
• if you are a consumer and you do not wish to continue using Comparisun under the new operator, you may close your account and stop using Comparisun at any time, free of charge; and
• we will only transfer to a company that is able to meet our obligations under these Terms, and a transfer will not reduce the guarantees or protections you have; and
• we will tell you who the new operator is and how to contact them, in line with Section 13 ("Change of controller / business transfer") of our Privacy Notice.

12.3 Your rights. You may not assign or transfer your rights or obligations under these Terms without our prior written consent, except that this does not restrict any statutory right you have to transfer a warranty or similar consumer right that attaches to goods you purchased.

13. Governing law and forum

13.1 General rule. These Terms are governed by the laws of the Republic of Cyprus (including the law of the European Union as it applies in Cyprus). Any dispute arising out of or in connection with these Terms that is not resolved informally may be brought before the courts of the Republic of Cyprus.

13.2 Your rights as a consumer are protected regardless of this clause. If you are a consumer habitually resident in the European Union, nothing in Section 13.1 deprives you of the protection of the mandatory consumer-protection provisions of the law of your country of habitual residence (Regulation (EC) No 593/2008 ("Rome I"), Article 6), and you may also bring proceedings against us in the courts of the EU Member State where you are domiciled, and be sued only there, under Regulation (EU) No 1215/2012 ("Brussels Ia"), Articles 17–18, or, if Luxa Energy LTD is established in Switzerland, Iceland or Norway, under the Lugano Convention (LugÜ), Articles 15–17.

13.3 If you are in Switzerland. If you are a consumer habitually resident in Switzerland, the law of your place of habitual residence applies to consumer contracts within Article 120 of the Swiss Federal Act on Private International Law (IPRG), and a choice of law does not displace it. You may bring proceedings at the courts of your own domicile or of Luxa Energy LTD's registered office, and we may bring proceedings against you only at the courts of your domicile (Article 114 IPRG, Article 32 Swiss Civil Procedure Code (ZPO) or, where applicable, Articles 15–17 LugÜ). You cannot waive this in advance.

13.4 If you are in the United Kingdom. If you are a consumer resident in the United Kingdom, you may bring proceedings in the courts of the part of the United Kingdom where you live (England and Wales, Scotland or Northern Ireland), and we may bring proceedings against you only in those courts. Nothing in this Section 13 deprives you of the protection of the mandatory law of that part of the United Kingdom where it is more favourable to you than the law governing these Terms (including under section 74 of the Consumer Rights Act 2015).

14. Complaints

14.1 Talk to us first. If you have a complaint about Comparisun itself (as opposed to about an Installer's product or service, which should go to the Installer), please contact us at support@comparisun.net. We aim to acknowledge complaints within 72 hours and resolve them promptly.

14.2 Your other options. This Section does not affect your right to contact your national consumer protection authority, or to go to court, at any time — see Section 13 for which courts have jurisdiction.

15. Miscellaneous

15.1 Severability. If any provision of these Terms is found unenforceable, the rest remain in effect, and the unenforceable provision will be read to give effect to its intent to the maximum extent the law allows.

15.2 No waiver. Our failure to enforce a provision is not a waiver of it.

15.3 Entire agreement. These Terms, including the ranking description incorporated under Section 5.1, are the entire agreement between you and Luxa Energy LTD regarding your use of Comparisun. Our Privacy Notice and Cookie Policy are information notices and are not part of this agreement. Nothing in this clause limits any statement we make to you, or any right you have, that the law does not allow to be excluded. They do not form part of, and do not replace, your purchase contract with an Installer (or, where applicable, with Luxa Energy as seller), which is governed by that contract's own terms.

15.4 Contact. Luxa Energy LTD, Chrysanthou Mylona 1, PANAYIDES BUILDING, 2nd floor, Flat/Office 1, 3030 Limassol, Cyprus. General enquiries: support@comparisun.net. Contract-related enquiries: support@comparisun.net.

15.5 Language. These Terms are provided in several languages. If the language versions differ, the English version prevails, except where the mandatory consumer law of your country of residence entitles you to rely on the version in your language.
