Asbestos in pre-2000 homes
An old night-storage heater is the type sometimes associated with asbestos and it was not sampled. Why must the survey not declare that heater free of asbestos?
The survey must not declare that heater free of asbestos because it was not sampled. An old night-storage heater of a type sometimes associated with asbestos was seen, and looking at the case is not a sample. Buildings built or refurbished before 2000 can contain asbestos. The visit has not identified the materials inside this heater, and it has not cleared them. A home survey does not decide that question by eye. The heater stays suspect until someone competent identifies it.

What is the fuller explanation?
Night-storage heaters of older patterns can contain insulating materials that need identifying before the unit is moved or opened. The survey can record the type of heater and that no sample was taken. It cannot see through the steel, and it must not call the contents free of asbestos on appearance. It also must not call them asbestos on appearance alone. Identification is a sampling task. The report's limit is the unsampled heater, not a clean bill and not a laboratory result.
Leave the heater undisturbed and ask an asbestos surveyor, not the home survey, if the unit is to be moved, opened or disposed of. Tell the solicitor the report has not cleared it. Do not describe a visual note as identification. Buildings of this age can hold asbestos in places a walk-round does not sample, and this heater is one such place until it is properly identified.
What should you ask your surveyor?
- What did you actually see of the night-storage heater without opening it?
- Was any sample taken, or is the heater unsampled?
- Did you avoid declaring the heater free of asbestos?
What are the typical next steps?
- Do not treat the heater as free of asbestos.
- Leave it undisturbed until it is identified by sampling.
- Keep the home survey separate from an asbestos survey.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.

If the casing looks clean, has the inside been cleared?
No. A clean casing is the outside. The survey did not sample the heater and must not declare it free of asbestos. Looking is not identification. Buildings built or refurbished before 2000 can contain asbestos, and this type of heater is only noted as sometimes associated with it. The contents stay unidentified.
Can the heater be carried out to the skip on the strength of this report?
No. The report did not sample it and did not identify what is inside. Moving or breaking into an unsampled heater is not something this survey authorises. Ask an asbestos surveyor before it is opened or taken away. The home survey has recorded a suspect unit, not a clearance to dispose of it.
