2007 Honda Jazz tight steering

[Brinyan]

Any opinions or advice here would be appreciated. My mother has a 2007 Jazz 1.2. It has lived its life from new on a small Scottish island. I have just driven it 750 miles back to Kent, taking its total mileage to 15,000.
The steering seems to need constant correction to straighten up after any turning of the wheel. It won't self centre. Feels fine otherwise, is light to park & I would say responds as it should, other than not self centring. Tyre pressures are fine & tyres in good condition.
Is this a common fault? Any lubrication points that need attention or adjustments that can be made?
I wonder if it's down to being exposed to the sea air?
Any advice would be appreciated.

Thanks for the feedback.
Going to get the car serviced & will get the steering checked out at the same time.
