The only way you're going to get any leverage here is to pay for an independent check of each appliance and then go to the landlord direct with the results. If they don't play ball then you can go down other routes but may end up getting asked to vacate the poperty.
Depends on what your landlord is like and how you approach them.
But, for peace of mind, start with getting your own checks done. Have been involved in a few where the landlord's 'usual guy' is unavailable to do some work and we've been asked in to do it. Whilst there, we flagged up some concerns over associated Gas equipment/installations.
'Usual guy' then magically returns and reports that all is fine to the Landlord!
From his POV, our opinion is gonna cost him money and his usual guy's opinion isn't.
So it all comes down to the section on the certificate that asks "safe to use?" and who's Gas safe credentials accompany it!
I'd also get that defective co alarm replaced and another one for the boiler.
