AI Summary
Based on 18 community reports
Calls from this London number on BT are repeatedly described as spam and suspicious. With 18 reports, the pattern includes foreign or robotic voices, automated messages, and several calls in one day. Some reports mention scams about damp problems or loft insulation, and one claims impersonation of a company called BRS; others say the caller asks for your name and then hangs up. Upvotes are not recorded for these reports, so reliability is mixed, though the spam score is high at 83/100. If you answer, be cautious; this looks likely to be a scam. Do not share personal information—hang up, block the number, and verify through official channels.

Another silent call. I hung up straight away as I think it's dangerous.
a foreign person asked me to say my name. when I asked who was calling, they hung up
SCAMMER! Said she is calling from BRS, whoever that is, but this is the same scammer that called on.
This morning at 8.30am - I had a chat with a foreign sounding caller, they said hello, I said hello, then the caller asked if I owned the property. I said no thanks goodbye and put the phone down. It was a scam for sure!
When I answered the phone, it was an automated message which just said GOODBYE. I think it's a scam.
