Some advice but not exactly ideal for people on low incomes is replacing old appliances. I have an old TV that consumed ~290 watts. Similar TVs today consume around 70 watts, say 25% for simplicity. Variable rate electricity tariffs are ~30p/kWh at the moment. At ~4 hours of TV a day (I guess more common for older households) 290W * 4 * 365 = 423.4kWh = £127 @ 30p/kWh vs 70W * 4 * 365 = 102.2kWh = £30 @ 30p/kWh So a £400-500 TV pays for itself in 5 years.
