As a general rule, to qualify for this exemption your conservatory should meet the following criteria laid out under the 1991 Building Regulations:

  1. The extension has a completely transparent or translucent roof;
  2. The extension walls are substantially glazed (no more than 25% of its wall area should be brickwork);
  3. The extension has a floor area not exceeding 30m2;
  4. The extension is sited at ground level.
