Brit entering UK NOT on UK passport

[Notnowjo]

Not quite sure where to put this but thought you guys might have the most experience. Family member (British subject or citizen whatever the latest is in passports) will be travelling to the UK in a couple of weeks, they’ve lost their UK passport so will need to travel on their other one (NZ if it is relevant). Are they likely to encounter any issues other than a long wait at passport control?! Thanks

All British Citizens have the right of abode in the United Kingdom. If, as a British Citizen, you wish to travel on a non-British passport it must be endorsed to show that you have the right of abode. Otherwise, you might experience difficulty proving your right to be re-admitted to the United Kingdom.

Pretty sure they will be able to just enter via the e-gates on an NZ passport? www.gov.uk/government/publications/coming-to-the-uk/faster-travel-through-the-uk-border

You can enter the UK on a kiwi passport without a visa - worst case they’ll enter as a “tourist” . Can they bring evidence that they’ve reported the lost uk passport and ordered a replacement? I’m a dual Nz/uk citizen with two passports and it has crossed my mind what to do in this situation.

Other evidence that would help in the face of an overzealous immigration officer would be proof of NI and NHS numbers as you can’t get them without the right to reside in uk (ie not an overstayer on a tourist visa in the ordinary course). I’d also practise masking my kiwi accent as best I can!

Do they have a scan/photocopy of their lost passport? Definitely bring that with if so.

On a general note it’s a really good idea to make and keep an electronic copy of your passport somewhere you can easily access in case of emergencies like this.

Birth certificate too if born in U.K. I've gone through multiple times on foreign passport in the past but it just causes stress at passport control if you get an officious passport control officer. Any supporting documents can help reduce the hassle, but make sure they're the right ones and up to date etc!

Coming for good or just to visit? I’m currently visiting the UK and used my US passport only. Breezed through immigration at Heathrow.

It was some time ago, but I used to switch between AUS/ UK passport depending on which line was shorter, it never caused me any difficulty.

Last time I visited the UK on my Aussie passport, I was grilled as to money, right to be in the UK, etc.

I've renewed my UK passport to avoid this.

No issues, though passport may be stamped on entry.
No point in telling border control of any other nationality held, it won't make any difference if you aren't entering on that passport.
The "latest" is British Citizen btw, and has been since 1983.

That's only really necessary if the person doesn't have a British passport. It would be necessary for someone who travels in and out of the UK a lot, for example, in order for them not to be seen as overstaying as a citizen of X and ppt holder of X when they also have ROA as a BC but not the passport which confirms it.
You can absolutely have a NI number if not regularly resident in the UK and it doesn't confirm nationality. As pp has said, neither does a birth certificate necessarily.

I haven't used my British passport since I left the UK 15 years ago and its never been an issue travelling on my other passport but now I'm travelling for the first time since Brexit fully happened I'm taking my expired British passport as well as the passport I'm travelling on, just in case, but I expect it'll just be a case of being treated as any other tourist and getting a stamp.

When we moved back to the UK from America with our 2 kids who were both under 3 they travelled on American passports as they didn’t have their British ones yet. We got told off at passport control, there passports were stamped with a date to leave the country and with something saying they weren’t allowed to work. We got their British passports shortly afterwards. This was 15 years ago so things may have changed.

Sea port or airport? We never have any problems at the sea port with DS1 (different name) or DS3 (dual national) even travelling on the "wrong" passport. Airport staff are very thorough.

Thanks team, very reassuring. FWIW they were booked to come through Dublin in the end and apart from a very ong trip it all went very smoothly!
