Why loft insulation is usually the first job worth doing

Heat rises, and an under-insulated loft is one of the fastest ways a property loses the heat it's already paying for. Topping up or replacing loft insulation is typically the cheapest, quickest measure on our list, most jobs are completed by our in-house team in a single visit, with no disruption to the rest of the house.

It's also the measure we recommend checking first before quoting a heat pump or heating system upgrade, since a well-insulated loft lets a smaller, cheaper-to-run heating system do the same job.
