I'd expect the OP will be paid a car allowance in lieu, rather than given a salary increase. In that scenario, they wouldn't benefit from an increase in company pension contributions as the allowance isn't base salary. That's how it operates where I work.I don’t know if you have an occupational pension scheme at work, but if you do and they match say 5% that also helps push it towards the pay rise. If you need a mortgage the extra 9k will help too.
