Do old fuse boxes really contain asbestos?
Many pre-1990 boards do — asbestos millboard flash guards and linings were standard arc protection. From the outside the board looks ordinary; the material is behind the fuses.
Can an electrician just remove the old board?
Not if asbestos is suspected — they are required to stop. The right order is test first, remove the material under controlled conditions if positive, then rewire.
What does testing a fuse board cost?
A UKAS-accredited lab test is £125. It settles the question in days and keeps a planned rewire on programme instead of stopping it mid-job.
Are old storage heaters dangerous?
Intact and in use, generally low risk. The risk moment is moving or scrapping them — some pre-1980s models contain asbestos insulation, so check the model or test before disposal.
