Delivery Schedule

For deliveries to non-mainland destinations including Northern Ireland, please contact us to arrange. Our aim is to deliver your order as soon as possible. Most products will be delivered within 3 working days, notable exceptions to this are made-to-measure shower tray formers (2 weeks), heated towel rails (2 weeks) and shower enclosures (1 to 4 weeks).

If your item is not in stock or is likely to be delayed for any other reason we will endeavour to make contact and give you the option of cancelling your order if you do not wish to wait.

All deliveries require a signature, if the first delivery attempt is unsuccessful, our delivery company will leave a contact card. If no contact is made they will then attempt a second delivery the following day, if the second delivery is also unsuccessful they will return the goods to our warehouse. You will then need to contact us to make further delivery arrangements at your own cost. We therefore, strongly advise that you give a delivery address where you know somebody will be available to receive goods during normal working hours.

Returns Policy

If any items arrive incomplete or damaged then please contact us immediately to arrange for replacements to be sent out. Please check carefully that your order is correct before proceeding as items incorrectly ordered and subsequently returned to us will be subject to a 25% re-stocking fee. Never return an item without contacting us to obtain a returns reference.

We regret that made-to-measure shower tray formers can not be returned or cancelled once your order is processed.

You may contact us for specific details but the guarantee periods offered are as follows: Caroflow Shower Outlets and Heated Towel Rails - 5 years, OTL Shower Tray Formers - 25 years, all other products - 10 years.
