Delivery information

FREE DELIVERY 

UK Stockholder

With such a wide range available to us, typically, we can pick your item right off the shelf and get it to you in no time. However, in some cases, we may need to special order certain items directly from the UK distributer to ensure you get exactly what you need. 

Delivered Safely

Master products are generally a little on the large side, therefore the delivery will usually by on a pallet and scheduled in with you. Tracking for pallet deliveries is limited to a day slot but we will endeavour to make this as convenient as possible. We have limited control over 3rd party couriers, but you should find the driver polite and accommodating.

Familiar Logistics Companies

When it comes to shipping smaller items and accessories, they are dispatched with DPD/Yodel on a next working day service. You'll receive timely updates on the progress of your shipment, and DPD/Yodel even offers convenient options if you can't be there to receive your delivery. At our store, we strive to make your shopping experience as seamless and hassle-free as possible.

Any Difficulties Please Call Us

While we strive to make the delivery experience as hassle-free as possible and ensure our drivers are polite and accommodating, please bear in mind that unforeseen circumstances can arise. If you have any issues with your delivery, our team is just a phone call away and will do everything they can to assist you. Please call 03301656200 is you are having any difficulties.

Returns & Damage Reporting Policy

We want to ensure every customer receives their order in perfect condition. To help us resolve any delivery issues quickly and effectively, we kindly ask all customers — both consumers and business buyers — to inspect their goods within 24 hours of delivery.

Inspection & Damage Reporting – All Customers

Please check your delivery carefully upon arrival. If there is any visible damage, defect, or missing item, you must notify us within 24 hours of delivery by contacting:

📞 0330 1656 200

📧 sales@aircareappliances.co.uk

Why this matters: Most courier services require damage claims to be submitted within 24–48 hours. Reporting issues promptly allows us to raise a claim on your behalf and resolve the matter as quickly as possible.

Failure to report damage within this timeframe may result in the claim being rejected, and we may be unable to offer a refund or replacement beyond this point.

Returns & Cancellations – Consumer Customers (Private Individuals)

If you are a consumer and have simply changed your mind, you are entitled to cancel your order within 14 calendar days of receiving the goods, under your statutory cooling-off period.

To be eligible for a full refund:

  • unused, in original packaging, and in a resalable condition
  • partial refund may apply

Refunds will be issued within 14 days of receiving the returned goods.

Returns – Business Customers (Trade / Commercial Buyers)

For all business purchases, cancellation rights under the Consumer Contracts Regulations do not apply. We do not accept returns for change-of-mind purchases on business orders unless agreed in writing at our discretion.

Any issues or damage must still be reported within 24 hours of delivery, as outlined above.

How to Arrange a Return

To request a return or report an issue, please contact us with your:

• Order number
• Details of the issue
• Photographic evidence, where applicable

Once approved, we will issue a Returns Number and Returns Form, which must accompany the returned item(s).
