Chiswick is overwhelmingly Victorian terraces and the Bedford Park Edwardian estate — almost all of it within conservation areas where external alterations are tightly restricted. IWI with vapour-permeable systems is the default specification here.

Internal Wall Insulation in Chiswick

We install internal wall insulation either side of Chiswick: a £5,300 IWI project in Shepherd's Bush (W12) in April 2025, and a £7,470 project in Hounslow (TW4) — our home postcode, ten minutes down the A4. That proximity matters in W4 because almost all of Bedford Park and the riverside terraces are conservation-protected: the brick frontages cannot change, so breathable boards fitted from the inside are the standard specification here.

Which insulation type is best for Chiswick homes?
Chiswick is overwhelmingly Victorian terraces and the Bedford Park Edwardian estate — almost all of it within conservation areas where external alterations are tightly restricted. IWI with vapour-permeable systems is the default specification here. The right choice depends on your wall construction (solid vs cavity), property age, and whether external alterations are permitted. Our free survey identifies the most cost-effective option for your specific home.
What does insulation cost in Chiswick?
Costs depend on property size, access and the measure: loft top-ups from around £400, floor insulation £2,500–£6,000, internal wall insulation from £100/m² and external wall insulation from £110/m². Every Chiswick quote is free, fixed and itemised after a survey — no surprises.
How long does insulation work take in a typical Chiswick home?
Loft top-ups are usually a 1-day job. Floor insulation takes 2-4 days depending on access. Internal wall insulation runs to 1-2 weeks for a full house, and external wall insulation typically 2-4 weeks including render and decoration.
