We plan to buy an oak engineered floor from you for our dining area and kitchen. It is 14mm thick from the manor collection. I need underlay. You advertise a budget underlay for £15.95 and a polyethylene DPM for £18. Do I need both - one on top of the other or will one of them do, in which case which one. Many thanks.

Regards Sean


If you are installing onto a wooden subfloor then there is no need for a moisture barrier or DPM. The budget underlay is only suitable to use on wooden subfloors. If you are installing onto a concrete subfloor then underlays such as the underlay supreme with moisture barrier or the pro gold will be fine.

I would like to know if this would be suitable to use on top of a cement screed with a wet system underfloor heating. If so, wether I were to use another underlay as well under suitable laminate flooring?


The best underlay to use for this would be the heat therm plus - The DPM sheet is not designed for underfloor heating systems.

When will my order arrive?

Our standard delivery provides orders to your door within 2-5 working days. As we want to ensure you’ll be available to receive the delivery in person we will contact you to discuss a time and date that is most convenient for you. This means we can’t ship any items out until we have spoken to you to confirm a date. Should there be any issues or delays likely for any reason, we will arrange an alternative date with you. Our priority is providing you with your flooring solution as quickly as possible at a time that suits you best.

How much will my delivery cost?

Can I choose a specific slot or a Saturday delivery?

If you need to receive your delivery within a tight timeframe, you can request for your flooring to be delivered at a specific time. This will incur a surcharge of £20, and is advised for those who will not be able to dedicate a full day to wait in for delivery. You can also request a morning delivery which has a surcharge of £12.50.

If you place your order any time throughout the week before 10am on Friday you can also choose to have a Saturday delivery slot. There is also a surcharge of £42.50 for this service.

Bought this along with engineered wood flooring. Great communication, delivery to suit me (order held for at least 5 weeks for me), nice product at best price on internet......would give 5 star but only 4 so far as floor not fitted yet.
