Location wrong on laptops, correct on Android

I live in England, postcode TA4 3JF.

Google maps, what3words etc on my Android, when connected to my home broadband, correctly identifies the location.

All 3 laptops in the house, 2 mine, 1 my wife's, give a location SA11 5LR, some 115 miles away.

I had thought it was the ISP but I recently changed ISP, indeed technologies, moving from wired Sky to satellite Starlink, and it hasn't changed.

The problem:

• Persists across multiple browsers
• Chrome location-internals shows kPlatformOnly, High Accuracy
• VPN and Windows default location setting make no difference

Could anyone suggest how I can get this fixed please?

Thanks
