I live in HA flats, there are 4 flats in my building. They are fairly new (3yo).
When we moved in we still had builders electric, water etc. After 4 months this stopped and myself and neighbours set up water meters etc. When the first bill appeared it siad I'd used no water so I went down to the cupboard and me and neighbours who's bills were obviously wrong (1 empty flat, 1 family with lowest bill, 1 single lady with highest bill, 1 lone parent family (me) with no bill)
Eventually it was sorted although water co were NOT helpful but cupboard had been locked at this point.
We asked for a key in case of emergencies as external stop clocks are in there but denied as its not our property. Much arguing with HA who didn't relent.
Anyway today plumber came to fix neighbours shower and on touching the pipe it came apart in his hands and shot water EVERYWHERE. I was comming in from getting my washing and not realising slipped and twisted my ankle.
Plumber came running in from outside and asked me where external stop cock was and said in the locked cupboard.
Plumber then had to stand inside airing cupboard and put pipe back together before internal stop cock could be switched off.
By this point the communal hallway was under 1" water and so I went upstairs and got all my towels and laid them down.
Now HA have been brill as was the plumber employed by them.
We again highlighted the importance of NEEDING access to external stop cock as the amount of damage ocured in 5 minutes was huge. (electrics, 3 flooded carpets etc).
On talking to housing officer all my neighbour got was 'well this happens in private houses too'
'YES but they can access the stop cock'
If this had been nighttime when it burst open then the damage done would have been phemonimal (espically if it had been a 1st floor flat) and stopping the wtare is cruical in leaks.
BIG boss came out and explained they have 1 key that opens all the cupboards and we can't have access to those. I suggested getting just one different lock for that cupboard with key for them. water co and resisdents. But they don't want to many keys to carry
. 1 more is obviosly too much.
I am now washing and tumbling all my and neighbours towels 
AIBU to think that we should be given access now in light of the situation and if they still refuse WWYD?
Sorry for the rant but so cross for neighbour.
