What is the "Stock Condition Survey"?

The recent service charge estimate included a "Stock Condition Survey" item. The one liner which comes with the letter does not really make clear what it's about.

I asked the BEO for a clear description. Here is what they said:

The stock condition survey will be looking at each block as a whole, but excluding any areas where we already have stock condition information. It will include internal areas within the block but not within leasehold properties. It will include items such as, but not limited to:

• Glazing
• Window Frames
• Doors
• Communal Electrical Installations
• Balconies
• Lifts
• Roofs (limited number)
• Drainage
• Generators

There will be other areas to survey in the Car Parks and Garchey
