ZSL Common terms

In these terms “ZSL” refers to the organisation or organisations relevant to your transaction as specified in the specific terms relating to each transaction type (the “Specific Terms”). The word “Terms” refers to the Specific Terms together with these Common Terms.

Amendments to the Terms

ZSL reserves the right to make changes to its website, policies, and the Terms at any time. You will be subject to the policies and Terms in force at the time that you use the website and or you enter into any transaction with ZSL, unless any change to those policies or these Terms is required to be made by law or government authority (in which case it will apply to orders previously placed by you). If any of these Terms are deemed invalid, void, or for any reason unenforceable, that term will be deemed severable and will not affect the validity and enforceability of any remaining term and the invalid or unenforceable provision will be deemed superseded by a valid, enforceable provision that most closely matches the intent of the original provision and the remainder of the agreement shall continue in effect.

Events beyond ZSL’s reasonable control

ZSL will not be held responsible for any delay or failure to comply with its obligations under these Terms if the delay or failure arises from any cause which is beyond its reasonable control. This term does not affect your statutory rights.


If you breach these Terms and ZSL takes no action, ZSL will still be entitled to use its rights and remedies in any other situation where you breach these Terms.

Other than liability for death or personal injury resulting from ZSL’s negligence, ZSL, its employees and or agents shall not be liable for any loss or damage, direct or indirect, howsoever arising out of or in connection with ZSL’s relationship with you to the extent permitted by law.

In the event that the above exclusion of liability is not effective, ZSL’s maximum aggregate liability (save in respect of death or personal injury resulting from ZSL’s negligence) shall be the amount paid by the claimant to ZSL in respect of the transaction out of which the claim against ZSL arose.

Entire Agreement

This agreement constitutes the entire agreement between you and ZSL in respect of the relevant transaction and it supersedes all prior or contemporaneous communications and proposals, whether electronic, oral, or written, between you and ZSL with respect to the transaction. A printed version of the Terms and of any notice given in electronic form shall be admissible in judicial or administrative proceedings based upon or relating to the Terms to the same extent and subject to the same conditions as other business documents and records originally generated and maintained in printed form.

Third Party Rights

None of the Terms shall be enforceable under the Contracts (Rights of Third Parties) Act 1999 by a party other than you or ZSL.


These Terms are governed by and shall be construed in accordance with English Law, and any claim brought under the Terms shall be subject to the exclusive jurisdiction of the English Courts.
