My M-I-L and family own a property which has recently been let. The letting is being handled by an agency and it's through them that the Gas Safety and Electrical Safety checks have been done.
Recently the tenants decided to change Gas/Electricity supplier and, as a result, a new smart meter has been installed. The installers of the smart meter have declared the gas installation to be unsafe, specifically they say the extract hood above the cooker doesn't have enough clearance and there isn't enough ventilation.
The Gas Safety Certificate was only issued a month or two ago so where do we stand on getting this sorted out? The Gas Safe engineer says it's safe but the gas supplier says it's not and has turned the gas off.
Aside from the above conflict and how to sort it out what are the rules (if any specific ones apply) about gas hob installations?
A quick search suggests that the height of an extract hood for a gas hob has a sort of default minimum of 750mm but tha this isn't actually mandatory, if the manufacturer says something else (less or more) then that's the 'right' clearance.
Similarly are there any exact rules about ventilation? It's a fairly typical medium sized kitchen in a modern terraced house. It has what was an outside window and door but these now open into what might be called a conservatory but is really just a small covered (but by no means well insulated) utility areas. It has a hatch (no doors) into the main living area and an internal door into the hall.
We obviously want to get this resolved as quickly (and cheaply) as possible while ensuring that things are safe. I expect the tenants are a bit fed up too!
