UK houses, the old ones usually have gaps and cracks around the doors and windows, and they are not very good at keeping the warm air inside. This makes your house feel cold. It also costs you a lot of money. In this guide, we will talk about why UK houses get so cold, how to find the spots, and what you can do to stop the cold air from getting into your house.

To keep the air out, we need to seal the gaps around the doors and windows. We can use weather stripping or a draft excluder to do this.
