What the work involves
Heating patterns, insulation gaps and cold bridges matter too, and some damp is not condensation at all: leaks, penetrating damp and rising damp need different trades. We tell you if that is what we find rather than selling a fan that will not help.
Fan upgrades
Weak or loft-vented fans replaced and ducted outside, with humidity control.
Whole-home ventilation
PIV, continuous extract or MVHR where moisture is spread through the house.

In Wales, ventilation follows the Welsh Approved Document F rather than the English version, with building control checking notifiable work. In Wales, damp and mould is one of the matters that decides whether a rented home is fit for human habitation.
