Would agree with CmairiD. The problem with tenanted property is probably that people do not feel they own anything and so they may treat it a bit rough.
Change of tenancy gas check rules, should have been brought in as common sense rules years ago, I think.
Funny thing is, in private property and its said 80% of UK housing is private. I must admit I would doubt that 80% are private owned, if you include Housing Associations as Landlords, but I am prepared to be corrected.
In private property, there is no requirement to have a gas safety check at any time. Its advised you do of course, but they cannot force you too.
So for a gas fitter going to a private house, you may walk into situations in which nothing has been checked for many years in point some may even go back as far as Victorian times.
Not recently I must admit, but I have seen houses with their original gas lights as well as the gas taps in the skirting board.
And as to ventilation or flueing Aaaah!
But back to tenanted property. I think another reason is carbon mon oxide poisoning.
The free accident solicitors are right on to that one. Even the slightest suggestion an appliance is not burning correctly and could be putting out Carbon mon oxide fumes, can lead to some tenants making a claim. And yes they probably know the gas regs better than the gas fitter.
The thing is most Housing Associations seem a bit scared of the HSE and so settle quickly rather than fight a case. Its probably cheaper all round to settle out of court.
However the HSE does seem to have a reputation of wanting to jail people for the smallest of mistakes, so obviously not many want them involved.
But of course, if your the last fitter who tested the property, then you better get ready for a grilling from all sides and by knowledgeable people.
You can't fob them off, by declaring your a Gas Safe fitter and so should not be questioned, just your word accepted as law. No Siree!
You have to prove how you have done things and to what standards you did them. In point you may have to go back to a property and repeat all your tests and show people the results and how they agree or disagree with the recognised standards.
In other words you are held accountable for your own work and to prove you did things right.
Must admit, we sometimes perhaps slipped up by passing what we regarded as chance remarks to tenants, who then used our remarks as a basis for a claim.
You know the type of scenario: Fire burning yellow "Can't that be left?", "No", "Why?" "It could lead to carbon mon oxide being given off!"
"That is dangerous!" "Its been like that for weeks!" "Where is my brief?"
As to room sealed boilers, well there is probably some reason to think that on the whole they could perhaps be left for longer than 12 months. The thing is nobody wants to take a chance of tenant damage.
I suppose though with more safety features such as defective seal sensors which cut the boiler out and others like it, their service period could be extended.
But then, "Who has been kicking a ball at the flue terminal and crushed it?"
"Who planted that shrub and allowed it to grow into the air brick?" and "Who let the other shrub grow over the flue terminal?"
"Who moved grannies bed into the front room with the recently installed open flued gas fire and back boiler?"
"Who filled up the inside vent with paper to stop the draft?"
"Who filled the gas cupboard with gloss paint tins and gas bottles?"
And on and on!
And despite all, gas fitters still do things wrong at times, they are humans and can make mistakes. So checking each year makes sure any faults should be picked up in a maximum period of 12 months.
In point I think some Housing Associations gave their houses out to a different service company each year.
Basically that meant each company checked each others service work. Must admit been in loads of fights because of this.
I suppose what seems, the policy now, of handing all the service work over to one big company for years on end because of financial considerations, does have this draw back.
I must admit I have been to sites where I have classed a lot of the service work as sub standard to find it had probably been done by the company I was working for, for years.
Hmm! Yes I suppose, I was then as popular as a boil on the posterior.
