If this is a council block, and it is a council "surveyor", then you are getting a typical instruction .... spend a little and hope for the best. The trouble is, all these little job costs, a few times a year can easily add up to the cost of one job and doing it right first time.
There are several options. Either they properly assess the flat and decide what is the actual cause - is it just a case of the tenant creating excess moisture or the property not being able to deal with modern living, or they decide if they are going to stick to their precise obligations and do nothing for condensation issues, or be pro-active and try and upgrade or adapt the property to cope better with condensation
It may be just a case of giving advice on heating, ventilation and dealing with humidity, or it could mean upgrading heating, insulating all the walls, fitting extract fans or fitting a positive pressure fan
The next thing normally done after your mould treatment, would be to line the walls with an insulated plasterboard. This may work, or if excess humidity is still present, then it could just shift the condensation to a different surface or part of the flat.
That is why condensation problems need to be looked at as a whole and not just dealt with piecemeal with a bit of fungicide. Treat the cause not the symptoms
