Having read old posts and the most recent gas hose question thread, i thought it would be useful to try to summarise the info briefly so people searching in future find the info quickly, so here goes (please feel free to add to, or correct).

Flexible gas hose has a manufactured date stamped on it.

It is good practice to replace it every 5 years or sooner if visual inspection shows wear, cracking, splits or damage

Don't use armoured or braided hose.
 
Just a note that the usual recommendation for 5 year replacement refers to 5 years from the date of manufacture, not the date of installation.

You'll probably find that some people will take issue with your warning on armoured/braided hose, although I'd agree with you.
 
For LP hoses I find the black LP hose, not being reinforced, is a lot easier to push on Fulham nozzles etc. Often shops only stock the orange HP hose which is a PITA.

Note that it is recommended that regulators are changed at 10 year intervals.
At the next change, if not sooner, it could be wise, if not essential, to fit one of the new Annexe M regulators designed for the marine environment.
 
The use of armoured hose is perfectly acceptable, and in some cases to be preferred over unprotected hose.

Are you sure of that, if the supplier has had it in stock 4 yrs you will have to replace it nxt yr too

From the Calor site
[Guide to using flexible hoses and tubing for LPG applications

Although no specific shelf life is usually quoted strict rotation should be maintained to avoid shortening the useful service life.
» Certification and quality assurance

Hoses and tubing are relatively vulnerable equipment that plays a vital and uniquely valuable role in the LPG Gas installation and they should be selected and stored with care. Any supply should be confirmed as having valid certification to BS3212 or BSEN1763 and have been manufactured under a quality system registered to BS EN ISO 9000. Stock should be stored carefully, avoiding bright sunlight, dampness, abrasion and excessive loading.
Although no specific shelf life is usually quoted strict rotation should be maintained to avoid shortening the useful service life.

» Service life

BS3212 or BSEN1763 hoses should bear the year and name of manufacturer.
We have no specific recommendation for the exchange interval for vapour hoses, but it is considered that the normal useful service life of such hoses is 5 years.
Aggressive operating conditions or simple misuse may render the hose unfit for service in a shorter time than 5 years. The User of the hose carries responsibility for routinely checking visually the hose(s) for signs of abrasion, cuts, cracks, fading, brittleness, hot spots or other damage. If the User has doubts about hose integrity then arrangements should be made for a competent person to check and if necessary, fit a replacement(s).
Dealers and Calor Centre delivery persons, caravan park operators, fitters and others who regularly come into contact with flexible hose applications may also participate in this regular visual inspection, and make appropriate recommendations to the customer/owner of the hose concerned.

For further information ion the safe use of flexible hoses and tubing please refer to the PDF “Using flexible hoses and tubing safely”.]

The problem with armoured hoses is that you cannot inspect the rubber internals. The hose below was only 2 years old when pictured (in my post from 2008, where others gave evidence of advanced perishing in new hoses http://www.ybw.com/forums/showthread.php?175523-Gas-hoses&highlight= ),

Would you contemplate living with that for another 3 years before you replaced it? 'Cause, if it was armoured, you would never know....
 
However, if the rubber was protected perhaps it would not suffer the same degradation. Armoured hose meets the BS and is useful when there is potential abrasion such as on a final connection to a gimballed cooker. The qualified engineer who did my installation insisted on fitting it and gave the safety certificate.
