Since October 2011 the water company owns the shared sewers and the lateral drain beyond your property boundary, and you own the private drains inside your boundary that serve only your home. If the blockage is in a shared pipe you can report it to Thames Water or Anglian Water for free. If it is on your side, that is where we come in, and a CCTV survey shows exactly which it is.
CCTV drain surveys start from £180. The price depends on the length and access of the drain run, and you get the recording, a plan of the run and a written report you can pass to a buyer, an insurer or a solicitor.
Inside the house it is nearly always fat, grease and wipes. Outside it is tree roots, collapsed or displaced clay sections on older properties, and silt from surface water. Repeated blockages in the same place are a sign the pipe itself is damaged, which is why we survey rather than just clear a drain that keeps coming back.
