Asbestos in pre-2000 homes
How should a buyer separate hair-felt lagging, the old cylinder and a covering that looking does not identify when all three are mentioned together?
Separate the lagging, the cylinder and the limit of looking. Hair-felt lagging is the old wrapping on the cylinder, the cylinder is where that wrapping sits, and a covering that looking does not identify cannot be called asbestos or cleared of it by eye. Buildings built or refurbished before 2000 can contain asbestos. The survey has not sampled this lagging and has not decided what it is made of. It has not called the covering safe, and it has not called it unsafe. The three names are not one test result.

What is the fuller explanation?
Hair felt was a traditional insulation wrapped around hot-water cylinders. Some old coverings of that general kind contain asbestos, and some do not. The Health and Safety Executive points out that asbestos can occur in buildings from before 2000, and that you do not identify it by looking. A surveyor can see a fibrous jacket, a cloth wrap or a painted skin. None of those sights is an analysis. The old cylinder dates the likely era. It does not analyse the fibres.
Tell the solicitor the lagging was not identified. If the cylinder is to be disturbed, for repair or replacement, ask an asbestos specialist before anyone works on the covering. Do not cut, scrape or break the lagging to see what is inside. The home survey has not sampled it and will not become a clearance because the jacket looks tidy. Leave it in place. The specialist, not the survey sentence, is who can arrange a proper identification. Until then the material stays unnamed.
What should you ask your surveyor?
- Was the hair-felt lagging intact, torn, or only partly seen?
- Did you record the cylinder as old, or was a date actually visible?
- Which parts of the covering were painted, cloth-wrapped or bare fibre?
What are the typical next steps?
- Keep the lagging, the old cylinder and the unidentified covering apart.
- Tell the solicitor looking did not identify the material.
- Ask an asbestos specialist before anyone disturbs the lagging.
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.
Also asked about this
Does a neat jacket mean the lagging is not asbestos?
No. A neat jacket is only what the eye could see. Buildings built or refurbished before 2000 can contain asbestos, and looking does not identify this covering. The survey has not called it safe or unsafe, and it has not sampled the hair-felt. Leave the lagging alone. Identification, if you need it, is a specialist matter, not a conclusion from a tidy surface.
Should the cylinder be stripped before you move in?
Not on the strength of this note. Stripping the lagging would disturb a covering the survey could not identify. The visit separated the hair felt, the old cylinder and that limit. It did not tell anyone to remove the jacket. Ask an asbestos specialist before any work on it. Until then the material stays undecided and undisturbed.
