It does what it says and screens out the unwanted calls and yet gives the opportunity of an announced call.

Delivering your online order

Get this delivered when it suits you

We’ll show you your current delivery options for this item in checkout. Subject to the time you order, and where you want delivery, these options will include:

  • FREE standard delivery in 5-10 working days
  • Next day delivery or any following day between 8am & 5pm (£5.00)
  • Delivery in a timeslot of your choice next day or any following day (£10.00)
Please note: if we’re out of stock of an item but getting more in, we indicate – on listings pages and the product page – how soon we can dispatch for delivery to you. In this case, please go ahead and order, and we’ll contact you later to confirm an exact delivery date.

Important update on our delivery service for small items

Our courier partners (DPD, Royal Mail and On the Dot) have all updated their delivery processes to take extra precautions due to Coronavirus (COVID-19). Please follow the below advice:

1. Customers can use the DPD app to nominate a ‘safe place’ for their delivery to be left if they do not want close contact.

For customers unable to use the DPD app, DPD is still able to offer a contact-free delivery, and will take a picture of the property and capture a proof of delivery name instead of capturing a customer signature.

2. Royal Mail is an unsigned service . Where Royal Mail needs to deliver a parcel, its teams will place the parcel at the customer’s door. Having knocked on the door, the delivery teams will step aside to a safe distance while the item is retrieved. If the delivery cannot take place, Royal Mail will take the parcel to the local depot for collection by the customer.  The parcel will be held for 18 days as per normal process.

3. For On the Dot, where a standard signature delivery is not possible, On the Dot will attempt to leave the parcel in a safe place and inform the customer of where the parcel has been placed.

To see the courier partner for your delivery, please check your dispatch confirmation email (which will also include your tracking reference).

Returns and refunds

Whether an item you’ve bought is faulty or damaged, or you’ve changed your mind, it’s easy to get a refund.

Items you haven’t opened
Within 21 days of receiving an item you paid for online, on the phone, or in store you can return it for a full refund – provided your purchase is still in its original and unopened packaging. This promise is in addition to your statutory rights.

Items you’ve opened

The item must be returned in ‘as new condition’ – not used or installed, and in its original packaging. More on returns and refunds.

Order online and collect in store

Sometimes you’ll want something even quicker than we can deliver. Or you can’t be in when our van or courier would arrive. That’s why we offer you the option to order online and collect in store.
Subject to what you’re ordering and where you want to collect from, you can:

Reserve & Collect – reserve online for free and collect at a local store as soon as you like. Once reserved, your item’s held till closing time the next day, to be paid for when you collect.

Pay & Collect – pay online, and have the item sent, for free, from our warehouse to a local store for you to collect. Starting on the date the item arrives in store – which you choose in checkout – you have 28 days to collect it.

Your fastest way to order online for collection is to use our ‘Availability Checker’ feature:

  1. Enter a town or postcode in the box on the product page for an item you’ve selected
  2. Click on the magnifying glass
  3. Review the collection options local to you – just click on any one to add it to your basket
