Practical insulation advice for warmer, cheaper homes
We assess heat loss, draughts, insulation levels and ventilation, then give you a clear action list for the property as it stands.
Find out whether your loft needs topping up, replacing or improving with hatch sealing, raised boarding or ventilation tweaks.
We explain cavity, solid wall and underfloor options in plain English, including where draught proofing delivers the quickest gain.
If you want to improve the home in stages, we map the best order so new insulation works with heating and ventilation.
