A few weeks ago, I bought my first home, a ground-floor flat in London. I didn't have a sofa, a dining table or a wardrobe, but before I even started looking at furniture, there was one £10 buy I bought almost as soon as I moved in: a letter box draught excluder.
A letterbox draught excluder costs around £5-10 on Amazon and is an internal flap that fits onto a door and often includes a brush seal.
