Expert Opinion
Claims about loft insulation checks, insisting neighbours have already sorted theirs, often signal unwanted cold calls pushing unnecessary services. Reports highlight persistent ringing despite blocks, and links to Twilio Ireland, a platform misused for spam by various outfits. Unknown origins and the Welsh area code add to the sketchiness, with some marking it as risky or harassing. Best move: never share personal details like age over unsolicited calls; block the number straight away and log it with the Information Commissioner's Office if it carries on. Enable call screening on your phone to filter out dodgy ones, and consider apps for spam detection to keep your line clear.

Scam
I suspect spam – they claimed I needed a loft‑insulation check even though the rest of the street has already had it, my house is only three years old. They asked for my age to schedule an appointment and hung up when I didn’t confirm anything.

Missed the ring on my mobile and left the call unanswered; I have no contacts in Wales, so I’m clueless about the caller’s identity or purpose.
The number originates from Twilio Ireland Limited, an Irish firm that lets other businesses use its line, and they know some of those clients employ it for spam calls. Not surprised at all.
