Commercial Terms



In these Terms of Trade we have used “we”, “us”, and “our” to refer to Chemwash Cleaning Ltd and “you” to refer to our customer. By ordering Work from us, you agree to these Terms of Trade to the exclusion of your terms (if any).


1.1  We will do the Work in accordance with our Quotation and these Terms of Trade.


2.1  Unless otherwise agreed in writing, quoted prices are in New Zealand dollars exclusive of GST and are valid for 30 days from that date of the Quotation unless withdrawn by us prior to acceptance.

2.2  You acknowledge that in accepting our Quotation you are relying on your own skill and judgement and not on any representations made by us about the suitability of the Work for your property.

2.3  We will not commence the Work until you have accepted our Quotation in writing (including Terms of Trade) which are then binding on you and may not be varied without our written consent.


3.1 Where we agree to do on-going Work for you:

(a)  the term of the contract will be the term specified in our Quotation and will automatically renew on a monthly basis unless terminated by you or us in accordance with clause 11; and

(b)  we may annually review our Quotation for the Work and make any reasonable adjustments to take account of increases in our costs.


4.1  The price for the work will be as set out in our invoice and may differ from our quoted price to take account of:

(a)  any variation in the Work from our Quotation (including any variation as a result of additional Work requested by you or required due to hidden or unidentifiable difficulties, delayed or obstructed/inadequate access and unavailability of a suitable free water source);

(b)  delays due to any third party occupying the property where the Work is to be done; or

(c)  increases in our costs for materials and labour which are beyond our control.

4.2  If you and any other person jointly ask us to do Work (or you ask us to do the Work on behalf of any third party), you are jointly and severally liable for all payments owing to us for that Work with that other person (or third party).

4.3  We issue accounts monthly and on completion of the Work.

4.4  Unless otherwise agreed in writing, the due date for payment of our accounts is the 20th of the month following the date of the account and all accounts must be paid in New Zealand dollars.

4.6  You must pay GST and any other government duties, levies and taxes in respect of the Work.

4.7  We may require you to pay a non-refundable deposit before we commence the Work.

4.8  If you do not make payment by the due date, you are in default and we may:

(a)  require you to pay default interest at the rate 5% per annum above the overdraft rate charged by our bankers, which will accrue on a daily basis on the total amount outstanding from the due date to the date of payment in full; or

(b)  if payment is outstanding for seven days from the due date, suspend performing the Work on credit until the date of payment in full, in which case you must pay in cash (on completion) for any Work done by us until payment is made in full (together with any accrued interest, legal costs (on a solicitor to client basis) and collection fees that we may incur in recovering (or attempting to recover) from you any overdue amount).

4.9  We may notify you at any time that we will no longer carry out the Work on credit.

4.10 Payment of all money owing for the Work must be made without set-off or deduction of any kind.

(c) Any delay in either replacing or remedying the workmanship or in properly assessing your claim.

7.2  The Consumer Guarantees Act 1993, the Fair Trading Act 1986, and other statutes may impose warranties, conditions or obligations upon us. We exclude all such imposed warranties, conditions or obligations to the extent permitted by law.

7.3  You acknowledge that the guarantees contained in the Consumer Guarantees Act 1993 are excluded where you acquire Work from us for the purposes of a business.
