Cambridgeshire Carpets supplies and fits quality underlay across Peterborough and the wider Cambridgeshire area, for carpet, laminate, LVT and engineered wood throughout PE1–PE7.

We include expert underlay advice with every flooring quote. Call 01733 924009 for a free home visit.
In short: underlay adds comfort, extends the life of the floor above it, improves thermal and acoustic insulation, and smooths minor subfloor imperfections. For carpet in Peterborough homes we typically recommend a 9–11mm PU foam underlay for living areas and a denser grade for stairs and hallways. Underlay is itemised in every quote, and supply-and-fit prices typically run from £4–£8/m² depending on the type.
Why Underlay Matters — More Than Just Comfort
It is tempting to economise on the part of the floor you cannot see, but the underlay does a remarkable amount of work:
- Comfort: a good underlay makes carpet feel luxurious underfoot and softens hard floors.
- Longevity: the right underlay can double the effective lifespan of the carpet above it by cushioning the pile against the subfloor and foot traffic.
- Thermal insulation: underlay reduces heat loss through the floor — valuable for comfort and for your EPC rating.
- Acoustic insulation: it absorbs impact and airborne sound — especially important in flats, upstairs rooms and rental properties.
- Subfloor smoothing: it masks minor undulations so the finished floor lies flat.
Types of Carpet Underlay We Supply
- PU foam underlay: the most popular choice for modern homes — light, warm, supportive and recyclable. Available in a range of thicknesses (typically 8–12mm) and densities. Ideal for living rooms, bedrooms and landings.
- Sponge rubber underlay: traditional, dense and very hard-wearing — excellent for heavy-traffic areas and stairs.
- Crumb rubber underlay: exceptionally durable and a strong acoustic performer — specified for stairs, hallways and contract settings.
- Felt and combination underlay: firm support favoured for some wool carpets and period properties.
We fit leading underlay brands including Cloud 9, Tredaire, Duralay and Ball & Young, and we match the grade to the room, the carpet and the subfloor.
Density, Thickness & Tog — Getting the Spec Right
Two carpets of the same price can feel completely different depending on the underlay beneath them. Density (measured in kg/m³) governs support and durability — a higher density resists flattening, which is why we use denser grades on stairs and in hallways. Thickness affects comfort but should be matched to the carpet; too thick under a heavy carpet can feel unstable. The tog rating indicates thermal insulation — useful where warmth matters, though over underfloor heating a lower-tog underlay is required so heat can pass through. We balance these for each room rather than fitting a single grade everywhere.
Underlay for Laminate, LVT & Engineered Wood
Hard floors need the right underlay too, but for different reasons. Floating laminate and click LVT require a thin, firm acoustic underlay that smooths the subfloor and dampens the hollow sound a floating floor can otherwise make, often with an integral damp-proof membrane over concrete. Engineered wood uses a specific acoustic or wood-flooring underlay depending on the fitting method. Using the wrong underlay under a hard floor causes movement, noise and premature joint wear, so we specify the correct product for each system.
Underlay & Underfloor Heating
Where there is underfloor heating — common in newer Peterborough homes in Hampton and Cardea — the underlay must have a low tog value so heat passes efficiently into the room. The combined tog of underlay and floor covering generally needs to stay within the manufacturer's limit. We select UFH-suitable underlay for carpet, laminate and LVT so your heating performs as intended and your floor lasts.
Stairs & High-Traffic Areas
Stairs, landings and hallways take the heaviest wear in any home, and they are exactly where a cheap underlay fails first. We fit a denser PU foam or crumb rubber underlay on stairs to resist flattening and protect the carpet on the nosings, which keeps the whole staircase looking smart for years longer. It is a small upgrade with a big effect on how the floor wears.
How Much Does Underlay Cost in Peterborough?
As a 2026 guide, supply-and-fit underlay in Peterborough typically costs £4–£6/m² for quality PU foam and £6–£8/m² for dense crumb rubber and premium acoustic grades, including fitting, gripper and any damp-proof membrane. Because underlay is fitted alongside your new floor, it is always itemised within your overall quote so you can see exactly what you are paying for. We measure in person and quote in writing — call 01733 924009.
Replacing Old Underlay
When we fit a new carpet we almost always recommend replacing the underlay at the same time. Old underlay that has compressed, crumbled or absorbed moisture will shorten the life of a brand-new carpet and undo much of its comfort. Fitting fresh underlay with a new carpet costs little extra at the point of fitting and protects your investment — we will always give you honest advice on whether existing underlay is worth keeping.
