Delivery
Delivery usually takes 3–5 working days. If you need your tiles sooner, just get in touch and we’ll do our best to help at helpdesk@tileflair.co.uk or 0117 959 8891.
We deliver across UK Mainland only.
We’ll confirm your order and arrange a kerbside delivery date that works for you. For safety reasons, drivers can’t bring items inside, so please plan to move tiles onto your property. If you’re not in on the agreed delivery date, and there’s no safe place to leave the order, a £30 redelivery fee will apply.
Please check your order when it arrives and let us know straight away if anything is missing or damaged so we can sort it out for you.

You can also return unopened, full boxes of tiles within 30 days, though returns over 20% of the original order may incur a restocking fee. Courier returns will need pallet collection. Please refer to our T&C section 8.
