We were using safety harness with shock absorber till one of our client discouraged the use of shock absorbers on harnesses. The reason cited was the elongation of lanyard and subsequent risks should a fall occur and the shock absorber breaks and elongates. Is there any law telling the height at which harnesses with energy absorbers are to be used. Lanyard is 6 feet and the energy absorber I presume is another 6 feet if it elongates fully.

No law, just guidance, standards, risk assessment and common sense.
You need to be working at a height high enough to allow the shock absorber to deploy and arrest the fall othrwise you will go splat!
A Retractable Lanyard / Fall Arrest Block may be a better solution.
Hope this helps.

WE AS A COMPANY HAVE A SIX METRE RULE. IF YOU WERE TO CONNECT YOUR LANYARD AT FOOT LEVEL AND WERE TO FALL YOU WOULD FALL THE HEIGHT OF A PERSON, eg 2METRES, LANYARD 1.75METRES AND SHOCK ABSORBER 1.75 APPROX TOTAL 5.5METRES. HOPEFULLY MISSING THE CONCRETE. SHOCK ABSORBERS ARE DESIGNED TO DISIPATE THE LOADING FROM A FALLING PERSON FROM 2 TONNE AS YOU FLY THROUGH THE AIR TO A 1/4 TONNE AS YOU COME TO A STOP SO THERE SHOULD BE NO POSSIBILITY OF STITCHING BREAKING, UNLESS YOU ARE USING TWINTAILED LANYARDS INCORRECTLY, THE LOADINGS ARE ONLY APPROX SO, LETS NOT START ANOTHER THREAD ABOUT LOADS. ADDITIONALLY THE HSE ADVISE THAT YOU USE A FIXED LANYARD WHEN USING A CHERRY PICKER BECAUSE OF THE POTENTIAL OF OVERTURNING THE MACHINE IF AT FULL EXTENSION OF THE BOOM.

Remember shock of the fall has to be reduced to below 6Kn force on the body

can you use fall restrint rather than fall arrest as this will limit / restrict how far you could travel.

Useful guidance can be found in an Appendix to HS(G)33, 'Health and Safety in Roofwork'.
In addition, you should always refer to the manufacturers' instructions (which should meet the requirements of BS EN 365).
The following HSE 'Q&A Briefing' on the new Work at Height Regulations may also helpful: http://www.hse.gov.uk/construction/pdf/fallsqa.pdf
Finally, comprehensive advice will be available shortly in BS 8437, 'Code of practice for the selection, use and maintenance of personal fall protection equipment and systems for use in the workplace'.
