Choose Next Day Delivery or a specific delivery date that suits YOU

All our underlays and accessories are held in stock for immediate delivery. The first step is to work out much carpet underlay you require, and we have three options to help you with this. The first is to use our room calculator at the top right had side of the screen, simply put in your room dimensions and the calculator will tell you the quantity you require as well as the number of gripper rods you may need.

The second option is to go to our Blog and find a section about “basic carpet & underlay planning”. The third option is to ring us and one of our sales team will work it out for you.

If you have a good look through our Blog you will find lots of helpful articles on what is the best type of carpet underlay you can buy for the selected area in your home. For example we stock Tredaire Dreamwalk which has a high tog rating which will help towards retaining heat in rooms at home that are cold. Tredaire Colours Red has a great db sound reduction which will help reduce the sound transmitted through the floors. Our range also includes Duralay Heatflow which is designed for underfloor heating and has a very low tog rating.

We also sell the more traditional carpet underlay such as wool felt and combinations that are half felt and half rubber crumb.

We at Underlay4u cannot over-emphasize that shopping online with us represents unbeatable value for money and means your carpet underlay can be as little as £1.93 plus Vat per sq meter for a high quality product that sells for more than £5.00 per m2 in high-street carpet retailers.
