It does look chafer grubs and leatherjackets. Most lawns are affected....destroyed sometimes....from autumn through to spring.
For the past 5 years or so my lawn has been fine because I used lawn grub killer. This is now banned. I will use nematodes this August.
Its too late now for any such treatment to your lawn Duckie. I certainly would not pay for any professional help.
I would spike the lawn....take your time.....when ground is not too wet. During a dry spell rake/scarify your lawn. This will make your lawn look awful, temporarily.
In late March or early April scatter lawn feed and then sow fresh grass seed...dwarf rye .......and lightly top dress if you can with compost .
Clearly your lawn is great in summer so I really don't think you have much of a drainage issue, etc........ simply leatherjackets and chafers so treat your lawn in August.
