It is not "simple" to measure work related illness as it is for accidents. That is why the HSE does not depend upon RIDDOR data comlpletely and has other measures.
In all the annual statistics reports from the HSE, including the latest one, the HSE has not been shy to highlight the number of deaths due to cancer etc or the cost of ill health etc to the GB economy.
The 2013-14 annual HSE statistics report STARTS with ill-health, not safety:-

1.2 million people who worked during the last year were suffering from an illness (long-standing as well as new cases) they believed was caused or made worse by their current or past work. 0.5 million of these were new conditions which started during the year.
A further 0.8 million former workers (who last worked over 12 months ago) were suffering from an illness which was caused or made worse by their past work.
2535 people died from mesothelioma in 2012 and thousands more from other occupational cancers and diseases such as COPD.
The report under the "work related ill-health heading states:-
Fatal diseases
Around 13 000 deaths each year from occupational lung disease and cancer are estimated to have been caused by past exposure, primarily to chemicals and dust at work.
This figure includes diseases for which it is possible to either count individual deaths directly, or where there is sufficient data to produce statistical estimates.
Most of these diseases take many years to develop and so deaths occurring now are largely a result of past workplace conditions.
Most of these deaths were occupational cancers or Chronic Obstructive Pulmonary Disease (COPD).
Current estimates (based on 2005 data) suggest there are at least 8000 occupational cancer deaths each year in Great Britain.
More than half of these cancer deaths were caused by past exposures to asbestos (either mesothelioma or asbestos-related lung cancer).
The next four biggest categories of occupational cancer were lung cancer due to silica, diesel engine exhaust, and mineral oils, and breast cancer due to shift work.
