There are 2 sources of fresh air entering your home, draughts and ventilation, the latter helps reduce condensation and damp, but the former if left uncontrolled can let in too much cold air and waste heat.
Draught proofing shouldn’t be much of a problem if you can handle simple DIY jobs. Most products should be available from good DIY shops.
However, some homes, especially older buildings with single glazing, will be more difficult to draught proof than others so you may need to get the help of a professional. More advice is available from the Energy Saving Trust.
