A guide to handling the waste from a loft conversion project in Scotland.
A loft conversion generates more waste than many homeowners expect. Proper planning ensures the project runs smoothly and waste is disposed of legally and efficiently.
How Much Waste Does a Loft Conversion Generate?
A typical loft conversion produces:
- Old insulation (fibreglass or mineral wool)
- Existing roof timbers and rafters
- Plasterboard from existing ceiling
- Old water tanks and pipework
- Brickwork if a dormer window is added
- Packaging from new materials
Recommended Skip Size
For most loft conversions, we recommend an 8-10 yard skip. If a dormer is being added with significant masonry work, consider a 10-12 yard skip.
Insulation Disposal
Old loft insulation requires careful handling:
- Wear gloves and a dust mask when handling old fibreglass insulation
- Bag insulation in heavy-duty bags before placing in the skip
- Modern insulation materials are not hazardous but older materials should be handled carefully
Asbestos in Older Properties
In houses built before the 1980s, asbestos may be present in:
- Old insulation boards
- Ceiling tiles
- Pipe lagging
If you suspect asbestos, stop work immediately and call a specialist. Asbestos cannot go in our skips and requires specialist removal.
Water Tank Removal
Old cold water tanks in lofts:
- Cannot go in the skip if containing asbestos-cement
- Plastic tanks are fine for the skip
- Metal tanks can be scrapped
Timing the Skip
For a loft conversion, we recommend:
- **First skip**: At the start for demolition and clearance waste
- **Second skip**: Towards the end for packaging, offcuts and finishing waste
