Well built, stable and with the raised platform above the top step it feels much safer to use. It has a good footprint spread on the ground and substantial feet which all contribute to stability. It allows me at 1.8metres tall to easily access and work on ceilings.


Amazing! Steady and safe, just what two old people who still DIY need! Thank you for your great service.


This is the best set of steps I have ever used. Very, very stable, which is what I really wanted. We are past retirement age - can't be doing with wobbly steps anymore! Actually, I bought the steps for my wife who insists on doing small things at height even though she is 73. (She had a mountain bike at 60, a new bike at 65 and a new wheelbarrow for her 70th birthday). Excellent delivery service as well. So, thanks a lot.

If there is another location to leave the delivery such as a safe place or with a neighbour the courier may opt for one of these alternatives. If it is not possible for the courier to leave the item elsewhere, the courier will leave a card at the delivery address confirming that they have attempted delivery.

How Do I Cancel an Order?

If you want to cancel an order that has not yet been delivered then you need to contact us as soon as possible. We will try and stop delivery so that a delivery charge is not incurred. Orders are normally processed immediately so we may have already packaged your order and made arrangements for it to be sent to you. If this is the case then we cannot always stop the order from being sent.

If you have received delivery and you want to cancel the order and return the goods, then you need to call, or email, so that we can send you a returns number.

In both cases, it will be helpful if you have the order number (from your order confirmation, or any update emails) and the date you placed the order handy. We will take some details and give you a returns number. This number has to accompany the return, both on the outside of the packaging and somewhere inside on a piece of paper.

We will expect the goods to be received back in our warehouse within 10 working days from notification of cancellation.

Please note: We will not refund your costs in returning the item to us unless you return the item to us because of an error on our part or because it is faulty. If you are a business there may be a restocking fee, depending on the item ordered.

We cannot cancel items made to your requirements if the manufacture of this item has been started. If you wish to cancel a bespoke product and the technical drawing has already been created, there may be a charge to cancel your order.

For your protection, we recommend that you use a Recorded Delivery service. We cannot issue refunds for goods that fail to reach us. Please note that you will be responsible for the cost of returning the goods to us unless we have delivered the item to you in error or the item is faulty.

Our returns policy does not cover goods made to order or bespoke items. They are not returnable.

How Do I Return My Order?

Please ensure that you contact us before returning anything as you will need a valid returns number.

  • Returns should be made within 30 days and in an adequate condition and suitably packaged for transit. You must include the original despatch note in the package you are returning to us
  • Ring us on 01204 590 232 or email us at [email protected] to notify us you'd like to return your item. Please quote your order number on your returned item. 

We will then advise you what address to send the return to or arrange a collection of the product. (If damaged) 

When Will I Get My Refund?

All returns arriving at our warehouse are processed within 3 working days. Unless we need to contact you further your refund will usually be processed with 7 days of receiving the returned goods and the absolute maximum time is taken should be no more than 30 days from you first contacting us to organise the return. Please remember that you will be responsible for the cost of returning the goods to us unless we have delivered the item to you in error or the item is faulty. If a discount was applied to your original order, the amount refunded will be adjusted to allow for the revised order value and appropriate discount level.

Depending on how your order was paid for will depend on how we process the refund. Please see below for more information:

Payment via Paypal - Paypal refunds are refunded directly to the account who made the purchase. This will usually show in your account within 3 to 5 days. 

Payment on Account - If your payment has been made by purchase order we will issue you with a credit note against your account.
