Got a call form this number 6.30 pm 26th November 2025. Not in my directory so did not answer and checked here. Phone recorded it as "Suspeted Spam". Do as I do and don't answer. If a genuine call, they will leave a message.

Definitely a scam, trying to get personal information. HMRC wouldn’t employ an outside company to obtain personal data.

Claimed to be from HMRC to discuss ''business plans'', did not sound legitimate at all. Agree with the other comment here.

Claimed to be from HMRC for a survey, suspicious intent.

Claims to be calling about a business survey, called 5 times yesterday and have tried blocking/blacklisting the number but they still seem to be able to get through. Clearly a scammer don't answer.

Sounded like a fake HMRC call. I said that I'd call back with a number off the website. I received at lease 3 calls from this number before I answered - and I answered thinking that that would stop them trying to call.
