The cost of life insurance in the UK can vary significantly based on factors such as your age, health, lifestyle, and the amount of coverage you choose. On average, a healthy individual might pay between £5 to £30 a month for a basic policy. However, premiums can be higher for those with pre-existing health conditions or those who smoke. It's best to compare quotes from different providers and consult with a regulated financial adviser to find the most suitable option for your needs.
