Terms of Service

Terms version 2026-10-16, the version recorded when an account accepts these Terms. Content last updated 2026-10-16.

Sunseam® is operated by Quantech Analytics Ltd (company number 15031177, England & Wales), trading as Sunseam (“we”, “us”). These Terms are for business users and are not legal advice. By creating an account or using the service you agree to these Terms and our Privacy Policy.

A. Terms of Service

1. Who we are & acceptance. Sunseam is operated by Quantech Analytics Ltd. By creating an account or using the service you agree to these Terms and our Privacy Policy. If you accept on behalf of a business, you confirm you have authority to bind it. The service is for business users (18+), not consumers.

2. The service. Sunseam provides commercial-solar roof intelligence: ranked rooftop opportunities and estimates for installers, and indicative savings estimates and installer matching for property owners.

3. Estimates are indicative, not advice or a guarantee. All figures (system size, generation, savings, payback, electricity spend, grid headroom, ownership, scores) are modelled estimates from public and third-party data, not a survey, audit, quote, or professional, financial, legal or engineering advice. They may be inaccurate or out of date. Do not rely on them as the sole basis for any decision; obtain professional advice and a site survey. We do not guarantee accuracy, completeness, leads, matches, savings, or any commercial outcome.

4. Accounts & security. Keep your credentials secure; you are responsible for activity under your account. One role per account (installer or business).

5. Acceptable use. You must not: scrape, bulk-export, resell, sublicense or redistribute our data or output except as expressly permitted by your plan; reverse-engineer the service; misuse personal data obtained through the platform; use it unlawfully or to send unlawful communications; or attempt to circumvent access controls or paywalls.

6. Leads, matching & contact data (installers). Where the platform shares a prospect's details. You may use them only to contact that prospect about solar for the site in question, in compliance with UK data-protection and PECR rules; you must honour opt-outs and not retain or repurpose the data beyond that. We do not guarantee the volume, quality, accuracy or exclusivity of any lead beyond what your agreement expressly states.

Exports. Data you export from the platform (including CSV downloads) is licensed to your account for your own business use, prospecting and fulfilment in the regions covered by your regional seat. You must not redistribute, resell, sublicense, publish or provide exported data (in bulk or systematically) to any third party, nor scrape, crawl or systematically extract platform data by any other means. Exports are watermarked with your account identity and logged. This licence ends when your regional seat ends, except for records you reasonably need of work already undertaken.

7. Property owners. By submitting your site you consent to us sharing your details with matched local installers so they may contact you (see Privacy Policy). You are under no obligation to proceed with any installer.

8. Intellectual property. We and our licensors own the platform, data compilations, scores and content. You get a limited, non-exclusive, non-transferable licence to use the service under your agreement. You retain rights to data you submit and grant us a licence to process it to provide and improve the service.

9. Disclaimers & liability. The service is provided “as is” without warranties. To the maximum extent permitted by law, we exclude implied warranties and are not liable for indirect or consequential loss, lost profits, or decisions made in reliance on estimates. Our total liability in any 12-month period is capped at the greater of the fees you paid us in that period or £100. Nothing limits liability that cannot be excluded by law (e.g. death or personal injury caused by negligence, or fraud).

10. Suspension & termination. We may suspend or terminate accounts for breach or misuse. You may close your account at any time (paid plans: see Subscription Terms). Clauses that by nature survive (IP, liability, acceptable use) continue after termination.

11. Changes. We may update these Terms and the service; material changes will be notified and continued use means acceptance.

12. Governing law. England & Wales; the courts of England & Wales have exclusive jurisdiction.

B. Installer account and regional seat terms

1. Regional seats. A regional seat gives your installer business agreed access to building data and research tools in the regions named in your agreement. There is no limit on how many installer businesses may hold a seat in a region. A seat is not a territory and gives no exclusivity over a region, a property or an owner.

2. Fees & billing. Your annual seat fee, payment schedule and any introduction fees are those recorded in your agreement, in GBP, exclusive of VAT where applicable.

3. Term, renewal & cancellation. A regional seat runs for the 12-month term in your agreement. Where your agreement is an annual subscription, it renews automatically each year at the price in your agreement until you cancel it. You can cancel from your account page at any time before a renewal date. It then does not renew, and your access continues to the end of the period you have paid for. Otherwise it ends at the end of that term unless a renewal is agreed in writing. Fees already paid are non-refundable except where your agreement or the law says otherwise. If you pay by instalments, the instalments for the full term remain due. If Sunseam does not serve a region named in your agreement when your payment arrives, we agree an alternative with you or refund the payment for that region. A subscription bought before these Terms continues on the terms it was bought under until it ends.

4. Price changes. The price in your agreement applies for its term. Any change applies only from a renewal, and we tell you before that renewal. Despite clause A.11, changes to these Terms do not alter your agreed fees, term, payment schedule or regions during the current term unless we both agree in writing, subject to clause A.10 and section C.

5. Introductions. Where your agreement includes introduction fees, it sets out the qualification criteria and the fee. Qualification uses the owner's declared role and project information; it does not verify authority over the roof or guarantee that the owner can be reached. Unless you have agreed automatic acceptance, you see a summary without the owner's details before deciding, and declining or letting an offer expire costs nothing; the fee becomes due when your business accepts and receives access to the introduction. With automatic acceptance, matching introductions are accepted and charged under your agreed criteria and monthly spending limit. An owner may authorise up to three installer businesses. We do not guarantee the number of introductions, a response, a quote or a sale. Credits for invalid, duplicate or out-of-scope introductions are given under your agreement; a credit does not create a further introduction.

6. End of access. When a seat ends, or a payment due under your agreement remains unpaid 14 days after we remind you, access to building data and research tools for that region ends. When no seat remains active, saved records, exports and introductions in the service are no longer available. Your installer account remains.

7. Regional changes. Adding, removing or exchanging a region is agreed in writing and is subject to Sunseam serving that region. A change does not shorten a term or create a refund unless agreed.

C. HM Land Registry data

1. Source and scope. Where the service displays information derived from HM Land Registry's Commercial and Corporate Ownership Data or Overseas Companies Ownership Data (together, the “HMLR Information”), it does so under licence from HM Land Registry, and this section applies. The HMLR Information is identified in the service by the attribution “Information produced by HM Land Registry © Crown copyright” with its dataset month.

2. Use within the service only. You may use the HMLR Information only within the service and for your own business purposes in evaluating and researching properties. You must not copy, sell, distribute, send, publish or otherwise make use of the HMLR Information for any other purpose, and you must not extract it from the service or combine it into any dataset, product or service of your own. You must not sub-license the HMLR Information further.

3. No direct marketing. You must not use the HMLR Information for the purposes of direct marketing, including but not limited to contacting registered proprietors to offer goods or services or to make other offers. Whether and how you contact any company about a property is your own decision and your own legal responsibility, including under UK GDPR and PECR; you must not rely on the HMLR Information as a marketing list or use it to compile one.

4. Title numbers and HM Land Registry systems. You must not use any HM Land Registry title number obtained from the service, or permit it to be used, in any way that causes HM Land Registry's systems (for example Business Gateway) or access to them to be interrupted, damaged or impaired.

5. Termination of HMLR rights. Your right to use the HMLR Information ends automatically if our licence from HM Land Registry ends, without affecting the rest of your agreement. In that event you must, no later than 48 hours after we notify you, delete or destroy any HMLR Information in your possession, custody or control, and we may certify your compliance to HM Land Registry.
