Generally speaking, LVP can be installed directly over subfloors such as concrete or ceramic tile assuming they're clean and level. Additional underlayment may be required if installing over existing hardwood or vinyl sheet floors to protect against moisture damage and sound transmission.
Flooring Underlayment
The thin layer of material helps cushion, sound absorption, insulation and reduce wear with your flooring. For laminate or engineered wood flooring, it provides a “vapor barrier” to prevent moisture from coming through and damaging your floor.
Why is underlay important? Underlay isn't just crucial for comfort underfoot, but it also drastically helps maintain your carpet as well as providing extra protection against moisture. It is also a great shock absorber, meaning it's ideal for reducing noise from things like footsteps, voices or moving furniture.

You may save time shopping and installing your floor if you skip the underlayment, but you will not achieve the optimal performance and longevity for your floor.

Very often, particularly in a below-grade installation on a concrete basement floor, a vapor barrier is recommended in addition to the underlayment. That vapor barrier would go between the subfloor and the underlayment.
It smooths out the subfloor
If you have areas in your subfloor that are bumpy, uneven or rough, laying carpet directly on it will lead to uneven wear and significantly shorten its lifespan. By installing underlay first you negate a lot of these imperfections, keeping your carpet looking its best for longer.
Underlay costs
As with carpets, underlay comes in a variety of materials, thicknesses and brands, each with their own uses and price points. Usually, the thicker, denser and more specialist it is, the more you can expect to pay.

If your planks already have a pad-attached underlayment, you most likely won't need an underlayment. However, if your flooring manufacturers installation instructions allow for an extra underlayment, adding an extra underlayment will provide improved sound reduction, insulation, and moisture protection.
