How does trade loft insulation work?
For new dwellings and extensions, the insulation has to match the design that achieved compliance, so we work from your SAP or U-value calculation and the specified product. We can install between and over the ceiling ties, fit eaves ventilation trays and loft hatches, and leave a boarded access route to services. More about trade loft insulation.

How much does trade loft insulation cost in Hertfordshire?
Trade prices are shown before any VAT. Work on new dwellings is normally zero-rated; extensions and refurbishment are normally standard-rated, and the construction reverse charge may apply. Each quote shows the VAT treatment.
Building regulations in England
In England, a loft insulated across more than half its area should reach a U-value of 0.16 W/m²K. Insulation alone is not usually notified to building control. How the rules work across the UK.

Are your prices the same across Hertfordshire?
Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.

Whatever the specification calls for, usually mineral wool rolls or loose fill, so the as-built matches the SAP calculation.
