Should a gas engineer make good the holes he left before leaving?

[Be kind]

Had carbon monoxide leak from boiler flue. Gas engineer came to fit new flue. But left gaping holes in wall. Daylight was seen

Yes, the engineer should make good holes where the flue exits to prevent products of combustion entering the premises.

Definitely get em back to make good needs to be sealed with sand and cement and ideally a weathering collar externally 👍 😉 kop
