The safety inspectors will be swooping unannounced on sites where refurbishment or repair works are underway.
The HSE will focus on working at height and work which could result in exposure to harmful dusts.
They will also that check that basic welfare facilities, such as toilets and handwashing facilities, have been provided.
Heather Bryant, HSE Chief Inspector of Construction, said: “Too many people die or are seriously injured every year on Britain’s construction sites as a result of entirely avoidable incidents.
“Just as importantly, workers are unnecessarily being exposed to serious health risks, such as asbestos or silica dust, which can have fatal or debilitating consequences.
“Often we find it is smaller companies working on refurbishment and repair work who are failing to protect their workers through a lack of awareness and poor control of risks.
“This initiative provides a chance to engage with these firms to help them understand what they need to do, so they can put in place the practical measures needed to keep people safe.
“However, let me be clear – if we find evidence that workers are being unnecessarily and irresponsibly put at risk we will not hesitate to take robust action. Companies who deliberately cut corners can expect to feel the full weight of the law.”
