If you're mostly covering local mileage and are able to charge at home via a home wallbox (installation of which will be around £1,000), an EV might actually make a lot of sense. They're also very easy and relaxing to drive. If you enjoyed your Peugeot 206 and 207, a Peugeot E-208 might be a look – £14,000-£15,000 will be plenty. You could go a bit lower to cover the cost of the wallbox installation, and still have enough for a young car with low mileage. If you'd prefer a petrol-powered car, for that sort of money we'd be looking at either a Volkswagen Polo or Skoda Fabia, which are closely related.
