The part you don’t see still matters.

Choose underlay for the job.

Underlay is part of the flooring system. The right type helps support the finish and affects the feel underfoot. A soft bedroom carpet and a busy staircase may need different support.

Existing underlay can have worn or compressed unevenly. Ask for it to be assessed instead of assuming it can be reused. Some floors have an integrated backing or specific fitting system and must not be paired with an arbitrary extra layer.

Find out what is underneath.

Tell us whether you have floorboards, concrete, tiles or an existing covering. Unevenness, movement or moisture may need attention before a new floor is fitted.

Photographs help start the discussion, but they do not replace an assessment. Preparation can affect the final cost and timing, so raise any known issues early.

A rough sketch is useful. A final measure is essential.

Sketch the room with doors, alcoves, fireplaces and any connecting spaces. Add approximate measurements if you have them, and mark the units clearly.

Ordering requires more than multiplying length by width. Roll widths, pile direction, pattern matching and joins all affect quantity. Stairs and unusual shapes need particular care; arrange a professional measure before committing to an order.

Mention underfloor heating at the start.

Bring the system details and any temperature requirements. The flooring and underlay must work together within the relevant manufacturer’s limits.

Compatibility belongs to a specific product and installation, so avoid choosing a floor based only on a general “works with underfloor heating” description.

Remember the edges.

Thresholds, skirting, door clearance and changes of floor height influence the finished room. Ask how transitions will be handled and what is included in the quote.

• Current floor and underlay condition.
• Heating details, if applicable.
• Doorways, steps and adjoining floor heights.
• Furniture, uplift and disposal arrangements to confirm.
