Floor Insulation in New Malden

New Malden is almost entirely 1930s semi-detached and Tudorbethan housing — the textbook UK property type for external wall insulation. Most homes have suspended timber floors and modest existing loft insulation that's well due a top-up.

Why New Malden homes benefit from floor insulation

Real comfort improvement

Most New Malden homes lose 25-35% of their heat through uninsulated walls or roofs. Floor Insulation cuts that loss dramatically and eliminates the cold spots and draughts that drive heating costs up.

Lower bills

A typical 3-bed home sees £300-£700 a year in heating bill savings depending on starting point and tariff. Depending on the measure, payback periods of 5-15 years are typical — with loft and floor insulation paying back fastest.

Adds value

Energy Performance Certificates feed directly into property valuations. Lifting an EPC band — common after this work — typically adds 1.5-3% to a home's sale price.

Frequently asked questions

How much does floor insulation cost in New Malden?
Pricing varies by property size, access and chosen materials. As a guide, expect £70-£140 per m² for full-system jobs. Every quote is free, fixed and includes labour, materials, scaffold (where needed) and making good — no surprises.
Do you handle planning permission for floor insulation in New Malden?
Floor Insulation usually falls under permitted development, but conservation areas (parts of New Malden are typically affected) and listed buildings need consent. We'll check your address against Greater London planning records during the survey and, where required, prepare drawings and submit on your behalf.
Are you certified to install floor insulation?
Yes — PAS2030-19 and TrustMark accredited, fully insured, and members of the relevant manufacturer-approved installer schemes (Kingspan, ROCKWOOL, SWIP, STEICO, Celotex). All work is backed by a written guarantee.
Will the work disrupt my New Malden home?
We minimise disruption by working in clearly defined zones, using dust-suppression methods, and protecting floors and furniture. For external work, scaffolding is the only outward sign — internal work is contained to one or two rooms at a time.
