Is normal behaviour from a water meter installer in the UK?

I had a Thames Water meter installation at my property recently and I’m unsure if the installer’s behaviour was normal.

During the visit, the installer asked me whether I live alone, which felt personal and unrelated to the job. He didn’t write it down or anything.

After leaving, he then contacted me directly on my personal phone number 3 hours later through WhatsApp and said he got my number “off the job” and claimed he may have left a tool (a spanner) at my property to try and collect it. I have checked and nothing was left behind.

I’ve reported it to Thames Water, but I’m trying to understand if this is normal contractor behaviour or if I should be more concerned about how my personal data was used.

Has anyone experienced anything similar or knows what the proper process is for contractors having customer phone numbers?
