According to this (2018, so fairly up to date) you can afford to live a basic lifestyle on 10k a year, so add 2k to that and you could probably (just about) afford a car, Netflix, an annual overseas holiday and a meal out once a month, bearing in mind their figures already include a UK holiday and public transport costs.
"£10,000 for a basic lifestyle
Currently, the State Pension is just £164.35 per week, which equates to £8,546 per year. Is that enough for a basic lifestyle?
Possibly not, according to recent research from the Joseph Rowntree Foundation (JRF), a respected charity. After surveying members of the public on retirement spending, JRF calculated that the income needed for a single retired person to live a minimum acceptable standard of living (more than just housing and food) is around £10,000 per year.
According to JRF’s calculations, £10,000 will provide enough money for a basic lifestyle that includes things like a mobile phone, internet access, alcohol, presents for grandchildren and a week’s holiday in the UK per year. However, the £10,000 figure also assumes that the individual uses public transport only, spends less than £20 per month at restaurants and has no luxuries such as pay TV or a dishwasher. "

Having lived on that amount (or less once you include rent) I would say yes, but I don't drive/own a car, regularly switch to the cheapest electricity and gas supplier, use cashback sites, cook mostly from scratch etc.
