We don’t give business customers all the same rights as consumers 

For example, business customers can’t cancel their orders, they have different rights where there is a problem with a product and we don’t compensate them in the same way for losses caused by us or our products. Where a term applies just to businesses or just to consumers, this is clearly stated. You are a business customer if you are buying products wholly or mainly for use in connection with your trade, business, craft or profession, even if you are an individual.

We will never contract with you except in accordance with these terms and conditions of contract.

When you buy from us you are agreeing that:

If you are a business customer this is our entire agreement with you

If you are a business customer these terms constitute the entire agreement between us in relation to your purchase. You acknowledge that you have not relied on any statement, promise, representation, assurance or warranty made or given by us or on our behalf which is not set out in these terms and that you have no claim for innocent or negligent misrepresentation or negligent misstatement based on any statement in this agreement.

We only accept orders when we’ve checked them 

We will contact you to confirm we’ve received your order and we will have accepted your order when:

  1. We advise you of the date and location for collection of the product(s); or
  2. You are contacted by the delivery company confirming to you that the product(s) are out for delivery to you desired location. 

Sometimes we reject orders

Notwithstanding our confirmation to you of acknowledgement of your order sometimes we reject orders, for example, 

  • because a product is unexpectedly out of stock, 
  • because a credit reference we have obtained is unsatisfactory, 
  • your account is on hold until previous invoices have been paid 
  • where your credit limit has been exceeded, 
  • because you are located outside our delivery areas, as stated on our website or
  • because the product was mispriced by us. 

When this happens, we let you know as soon as possible and refund any sums you have paid.

We retain the right to reject any order entirely at our discretion.

We charge you when you order 

Unless we have an agreed charging process with you we will take payment for the goods subject to our right to reject the order at the point at which you place your order. The time when you place your order is 

  • Website: make payment for goods through our website
  • Email: if you are a credit account customer, the point at which we receive and open your email confirming the details of your order, otherwise when you confirm your payment details for the goods.
  • Telephone or fax: you confirm your payment details for the goods.

If you are a business customer you have no set-off rights. If you are a business customer you must pay all amounts due to us under these terms in full without any set-off, counterclaim, deduction or withholding (other than any deduction or withholding of tax as required by law).

We charge interest on late payments

If we are unable to collect any payment you owe us we charge interest on the overdue amount at the rate of 8% a year above the Bank of England base rate from time to time. This interest accrues on a daily basis from the due date until the date of actual payment of the overdue amount, whether before or after judgment. You pay us the interest together with any overdue amount. 

We pass on increases in VAT

If the rate of VAT changes between your order date and the date we supply the product, we adjust the rate of VAT that you pay, unless you have already paid in full before the change in the rate of VAT takes effect.

We’re not responsible for delays outside our control 

If our supply of your product is delayed by an event outside our control, we contact you as soon as possible to let you know and do what we can to reduce the delay. As long as we do this, we won’t compensate you for the delay, but if the delay is likely to be substantial you can contact our Customer Service Team: to end the contract and receive a refund for any products you have paid for in advance, but not received, less reasonable costs we have already incurred. 

Delivery Delays

We use third-party delivery organisations and are not responsible for their delays in effecting delivery. 

Products can vary slightly from their pictures 

A product’s true colour may not exactly match that shown on your device or in our marketing or its packaging may be slightly different. Because some of our products are handmade, all sizes, weights, capacities, dimensions and measurements indicated on our website can be out by up to 5%.

You’re responsible for making sure your measurements are accurate 

If we’re making or supplying the product to measurements you provide, you’re responsible for making sure those measurements are correct. Find information and tips on how to measure on our website and in our brochure or contact our Customer Service Team:

We charge you if you don’t give us information we need or do preparatory work as agreed with us

We charge you additional sums if you don’t give us information we’ve asked for about how we can access your property for delivery, installation or to provide services or if you don’t do preparatory work for installation, as agreed with us. For example, we might need to re-deliver on another vehicle or with extra manpower or reschedule services.

If you are a consumer and you either bought online, by email order, or over the telephone you have a legal right to change your mind.

Your legal right to change your mind. For most of our products either bought online, by email order, or over the telephone you have a legal right to change your mind about your purchase and receive a refund of what you paid for it, including the delivery costs. This is subject to some conditions, as set out below.

Your legal rights
14 days to change your mind.
You pay costs of return

When you can’t change your mind. You can’t change your mind about an order for: 

  • services, once these have been completed;
  • Appreciate this is standard terminology but can be removed as not appropriate for our business goods that are made to your specifications or are clearly personalised; and
  • goods which become mixed inseparably with other items after their delivery.

The deadline for changing your mind. If you change your mind about a product you must let us know no later than 14 days after:

  • the day we deliver your product, if it is goods. If the goods are for regular delivery (for example, a subscription), you can only change your mind after the first delivery. If the goods are split into several deliveries over different days, the period runs from the day after the last delivery. 

How to let us know. To let us know you want to change your mind, contact our Customer Service Team:

You have to return the product at your own cost. If your product is goods, you have to return it to us within 14 days of your telling us you have changed your mind. Returns are at your own cost. However, prior to returning goods you will be required to complete a Returns form which can be found at our website 

You can bring the product to one of our warehouses the details of which can also be found on our website. You will need your email receipt and the card you paid with. 

We don’t refund any extra you have paid for express delivery or delivery at a particular time.

Please note that our delivery charges are not refundable if you decide to reject the goods.

You have to pay for services you received before you change your mind. If you bought a service we don’t refund you for the time you were receiving it before you told us you’d changed your mind. 

We reduce your refund if you have used or damaged a product. If you handle the product in a way which would not be acceptable in-store, we reduce your refund, to compensate us for its reduced value. For example, we reduce your refund if the product’s condition is not “as new”, price tags have been removed, the packaging is damaged or accessories are missing. In some cases, because of the way you have treated the product, no refund may be due. Our Customer Service Team: can advise you on whether we’re likely to reduce your refund.

When and how we refund you. If your product is a service, digital content or goods that haven’t been delivered or that we’re collecting from you, we refund you as soon as possible and within 14 days of you telling us you’ve changed your mind. If your product is goods that you’re sending back to us, we refund you within 14 days of receiving them back from you (or receiving evidence you’ve sent them to us). We refund you by the method you used for payment. We don’t charge a fee for the refund.

You can end an on-going contract (find out how)

We tell you when and how you can end an on-going contract with us (for example, for regular services or a subscription to digital content or goods) during the order process and we confirm this information to you in writing after we’ve accepted your order. If you have any questions, please contact our Customer Service Team:

Your rights and remedies if you are a consumer. We honour our legal duty to provide you with products that are as described to you on our website and that meet all the requirements imposed by law.

We can change products and these terms

Changes we can always make. We can always change a product:

  • to reflect changes in relevant laws and regulatory requirements; and
  • to make minor technical adjustments and improvements, for example to address a security threat. These are changes that don’t affect your use of the product.

Changes we can only make if we give you notice and an option to terminate. We can also make the following types of change to the product or these terms, but if we do so we’ll notify you and you can then contact our Customer Service Team: to end the contract before the change takes effect and receive a refund for any products you’ve paid for in advance..

We don’t compensate you for all losses caused by us or our products

Our liability to consumers. We’re responsible for losses you suffer caused by us breaking this contract unless the loss is:

  • Unexpected. It was not obvious that it would happen and nothing you said to us before we accepted your order meant we should have expected it (so, in the law, the loss was unforeseeable).
  • Caused by a delaying event outside our control. As long as we have taken the steps set out in the section We’re not responsible for delays outside our control. This includes delays caused by transport or courier companies who are delivering the goods to you.
  • Avoidable. Something you could have avoided by taking reasonable action. For example, damage to your own digital content or device, which was caused by digital content we supplied and which you could have avoided by following our advice to apply a free update or by correctly following the installation instructions or having the minimum system requirements advised by us.
  • A business loss. Our liability for any loss you suffer in connection with your trade, business, craft or profession is limited, as described in Our liability to businesses.

Our liability to businesses. If you’re a business, then, except in respect of the losses described in Losses we never limit or exclude: 

  • we shall not be liable to you, whether in contract, tort (including negligence), breach of statutory duty, or otherwise, for any loss of profit, or any indirect or consequential loss arising under or in connection with any contract between us; and
  • our total liability to you for all other losses arising under or in connection with any contract between us, whether in contract, tort (including negligence), breach of statutory duty, or otherwise, shall be limited to the total sums paid by you for products under such contract.

  • death or personal injury caused by our negligence, or the negligence of our employees, agents or subcontractors (as applicable);
  • fraud or fraudulent misrepresentation;
  • breach of the terms implied by section 12 of the Sale of Goods Act 1979 or section 2 of the Supply of Goods and Services Act 1982; or

No implied terms about goods. Except to the extent expressly stated in Your rights if you are a business, we exclude all terms implied by sections 13 to 15 of the Sale of Goods Act 1979 and sections 3 to 5 of the Supply of Goods and Services Act 1982.
