Property assessment and installation are arranged by postcode across the South West. Major service areas:
Housing in the South West and what it means for insulation
Bristol and Bath bring Georgian and Victorian terraces — some listed — alongside inter-war suburbs; Cheltenham and Gloucester mix Regency and 1930s stock; Devon and Cornwall are full of older cottages, cob and stone walls, slate roofs and holiday-let conversions. Swindon and Plymouth have large post-war estates. Exposure and driving rain on the coast make ventilation and moisture the first survey question.

Slate, cob and driving rain
Old slate roofs on shallow rafters, breathable cob and stone walls, and coastal exposure make moisture and breathability the first questions across Devon, Cornwall and Somerset; foil is a roof conversation here, not a wall one.
Why foil may suit some homes here
Slate roofs on old rafters with no depth to spare and owners who cannot raise the ridge are where multifoil under the rafters is worth investigating. The decision rests on the whole roof build-up — rafter depth, ventilation, moisture, existing insulation and intended use — not on material thickness alone. Foil insulation guide.
Why foil may not suit others
Stone and cob walls need breathable, designed systems; foil is not a wall answer in this stock. A straightforward cold loft with good access is often more appropriately upgraded with conventional mineral-wool loft insulation than a rafter-level foil system, and we say so when it is.

What foil insulation costs in the South West
We do not publish invented regional prices. What moves a quote here is the same as anywhere else:
- property size and roof area
- access to the loft or roof space
- what insulation is there now and whether it stays
- the system selected — multifoil alone, multifoil with PIR, or an alternative
- preparation work, including removal of old material or spray foam
- ventilation and detailing at eaves, dormers and penetrations
National indicative ranges are in the foil insulation cost guide; as genuine project data from the South West builds, regional ranges will be published here.
