Tests that do not involve the dispatch of physical kits or products and no testing has been completed can be cancelled within 7 days with a full refund being issued within 30 days.

We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the results of unnecessary handling by you where testing kits or products are issued.

We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of the reimbursement.

We may withhold reimbursement until we have received the goods back or you have supplied evidence of having sent back the goods, whichever is the earliest.

You shall send back the goods or hand them over to us without undue delay, no later than 14 days from the day on which you communicate your cancellation from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired.

You will have to bear the direct cost of returning the goods.

You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.

If the testing kit, which is deemed as a perishable item, has been opened or damaged, we reserve the right to charge a £15 fee deduction from any refund due.

If you have purchased a test through a third party, then you need to contact the company you originally ordered from in order to exercise your cancellation rights and/or receive a refund.
