Terms & Conditions

Terms and conditions of sale for lead generation and lead supply services.
Last updated: 5 October 2026

1. Introduction

These terms and conditions (the “Terms”) govern the supply of sales leads and related lead generation services by A-Z Zenith Technologies Ltd, a private limited company registered in England and Wales under company number 15319259, whose registered office is at 167-169 Great Portland Street, 5th Floor, London, England, W1W 5PF (the “Supplier”, “we”, “us”), to any business customer (the “Client”, “you”).

By opening an account with us, placing an order, requesting or accepting the delivery of Leads, the Client accepts these Terms in full. These Terms apply to the exclusion of any other terms the Client seeks to impose or incorporate. They are intended for business-to-business relationships only.

2. Definitions

“Lead” means any enquiry, request for a quote, contact, registration, call or set of contact details submitted by an end user and transmitted or made available to the Client.
“Websites” means the websites, landing pages and digital properties operated, published or controlled by the Supplier.
“Forms” means any enquiry or quote form, widget, call module, script, iframe or other data-capture mechanism displayed on the Websites, whether operated by the Supplier or by a third party.
“Order” means any order, insertion order, account set-up or written or electronic agreement for the supply of Leads.

3. Services

The Supplier generates Leads through its network of Websites and supplies those Leads to the Client in the niches, volumes, territories and at the prices agreed in the applicable Order. Unless expressly agreed in writing, Leads are supplied on a non-exclusive basis and no minimum or maximum volume is guaranteed.

4. Generation and attribution of Leads — payment is due

This is an essential term of the agreement and a condition of the supply:

4.1 The Client acknowledges and agrees that every Lead generated through the Supplier’s Websites is attributable to the Supplier and is chargeable and payable to the Supplier under these Terms, whether that Lead is captured:

(a) by the Supplier’s own enquiry or quote Forms; or
(b) by any third-party Form, widget, iframe, script, call module or integration that is embedded, displayed, hosted or otherwise made available on the Supplier’s Websites (including any form or integration operated by the Client, a partner, a buyer or any other third party).

4.2 Accordingly, any Lead, enquiry, call or contact originating from a user of the Supplier’s Websites is deemed to have been generated by the Supplier and gives rise to payment under these Terms, regardless of the technical means of capture or of the party operating the Form.

4.3 The Client shall not withhold, avoid or reduce payment, and shall not dispute the attribution of a Lead, on the basis that the Lead was collected, routed or processed through a third-party Form or integration rather than through the Supplier’s own Forms.

5. Delivery of Leads

Leads are delivered in real time or at the frequency agreed in the Order, by the method agreed between the parties (for example email, feed, webhook, API or export). Risk and responsibility for the use of a Lead pass to the Client on delivery or on the Lead being made available to the Client.

6. Lead quality and claims

6.1 The Supplier takes reasonable care to supply genuine Leads matching the agreed criteria. The Supplier does not, however, warrant that any Lead will convert into a sale, an appointment or any particular outcome.

6.2 A Lead may be reported as invalid only where the contact details are manifestly false or non-existent, or where the Lead is an exact duplicate of a Lead already supplied, or is plainly outside the agreed niche or territory. Any such claim must be notified in writing (including by email) within five (5) working days of delivery, failing which the Lead is deemed accepted and valid.

6.3 Where a claim is accepted by the Supplier, the sole and exclusive remedy is, at the Supplier’s option, the replacement of the Lead or the grant of a credit for that Lead. For the avoidance of doubt, a claim or dispute does not suspend the Client’s obligation to pay the sums otherwise due.

7. Prices

Prices are those set out in the applicable Order or price list and are stated exclusive of VAT and any other applicable taxes, which the Client shall pay in addition where chargeable. The Supplier may revise its prices for future Leads on reasonable prior written notice.

8. Invoicing and payment

8.1 The Supplier invoices the Client for the Leads generated, typically on a periodic (for example weekly or monthly) basis. Invoices are payable within seven (7) days of the invoice date, unless otherwise agreed in writing.

8.2 All sums are payable without set-off, deduction or counterclaim.

8.3 Overdue sums shall bear interest and the Supplier shall be entitled to compensation for recovery costs in accordance with the Late Payment of Commercial Debts (Interest) Act 1998. The Supplier may also suspend the supply of further Leads while any sum remains overdue.

9. Term and termination — one month’s notice

9.1 The agreement begins when the Client first opens an account, places an Order or accepts a Lead, and continues until terminated in accordance with this clause.

9.2 Either party may terminate the agreement for convenience by giving the other party at least one (1) month’s (thirty (30) days’) prior written notice. Notice given by email to the other party’s usual contact address is sufficient. The agreement remains in full force, and Leads continue to be supplied and charged, throughout the notice period.

9.3 Either party may terminate with immediate effect by written notice if the other commits a material breach which is not remedied within fourteen (14) days of being asked to do so, or becomes insolvent or unable to pay its debts.

9.4 Termination does not affect any Leads already generated, delivered or made available, or any sums accrued or payable, up to the effective date of termination, all of which remain fully due and payable.

10. Non-circumvention

During the agreement and for twelve (12) months after it ends, the Client shall not seek to bypass the Supplier, or to avoid or reduce the fees payable under these Terms, by capturing, diverting or taking delivery of Leads generated through the Supplier’s Websites otherwise than under these Terms, including by means of any third-party Form or integration placed on the Websites.

11. Data protection

Leads contain personal data. Each party shall comply with the UK GDPR and the Data Protection Act 2018. The Supplier confirms that end users have been informed and, where required, have consented to the transmission of their details to the Client for the relevant purpose. Once a Lead is delivered, the Client acts as an independent controller of that personal data and is responsible for processing it lawfully, including honouring the data subject’s rights and using the data only for the purpose for which it was provided.

12. Warranties and limitation of liability

Nothing in these Terms limits liability for death or personal injury caused by negligence, for fraud, or for any other liability that cannot lawfully be excluded. Subject to that, the Supplier’s total liability arising out of or in connection with the agreement shall not exceed the total amount paid by the Client to the Supplier in the three (3) months preceding the event giving rise to the claim, and the Supplier shall not be liable for any loss of profit, loss of business, loss of revenue or any indirect or consequential loss.

13. Confidentiality

Each party shall keep confidential the commercial terms of the agreement and any non-public information disclosed by the other, and shall use it only for the purpose of performing the agreement.

14. Force majeure

Neither party is liable for any failure or delay in performing its obligations (other than an obligation to pay) caused by events beyond its reasonable control.

15. General

These Terms, together with the applicable Order, constitute the entire agreement between the parties. The Supplier may update these Terms on reasonable notice; the version in force applies to Leads supplied after it takes effect. If any provision is held unenforceable, the remaining provisions continue in force. Neither party may assign the agreement without the other’s written consent, such consent not to be unreasonably withheld.

16. Governing law and jurisdiction

These Terms and any dispute or claim arising out of or in connection with them are governed by the laws of England and Wales, and the parties submit to the exclusive jurisdiction of the courts of England and Wales.
