About us
DASA (Drainage Advisory Services and Assistance Limited) provides drainage and leak detection services to insurers, businesses and homeowners across the UK. DASA is part of the Sigo Group of companies.
This statement summarises our approach to preventing modern slavery and human trafficking. Our separate Modern Slavery and Human Trafficking Policy, which is available on request, sets out the responsibilities, controls and reporting arrangements that support it.
DASA is not required to publish a statement under section 54 of the Modern Slavery Act 2015 because our annual turnover is below the £36 million threshold. We publish this statement voluntarily because we believe it is the right thing to do.
Our commitment
Modern slavery includes slavery, servitude, forced or compulsory labour and human trafficking. We do not tolerate modern slavery, human trafficking or exploitation in our business or supply chain, and we expect the same standards from everyone we work with. We are committed to acting ethically and with integrity in all our business relationships.
Where the risks are
We assess risk proportionately, considering labour arrangements, the level of subcontracting and worker vulnerability. The areas where we consider the risk to be highest are:
- subcontracted labour, including drainage, excavation and reinstatement contractors working on our behalf;
- agency and temporary workers; and
- goods we buy in, such as equipment, PPE, workwear and vehicles, where manufacturing may take place in higher-risk countries.
Our supply chain
We expect suppliers, subcontractors and partners to uphold equivalent standards, including in their own supply chains. In practice this means:
- subcontractors complete our onboarding process, which includes confirming that their operatives have the right to work in the UK;
- our contracts and supplier agreements include modern slavery and ethical labour clauses; and
- we carry out proportionate checks and take corrective action where needed, which may include ending a relationship if a supplier will not address a concern.
Our policies and people
Our policies support responsible recruitment, ethical procurement, supplier oversight and the investigation of concerns. They include our Modern Slavery and Human Trafficking Policy, Whistleblowing Policy and Recruitment Policy.
We carry out right to work checks on everyone we employ, pay at least the National Minimum Wage, and never ask workers to pay recruitment fees or hand over their identity documents.
Employees receive training on the warning signs of modern slavery, their responsibilities and how to raise a concern at induction and every year after that.
Measuring effectiveness
We review this statement and our approach every year. To check our approach is working, we monitor completion of training, subcontractor onboarding checks, and any concerns raised and how they were resolved.
Raising a concern
If you are concerned about possible modern slavery connected to DASA, our supply chain or anyone we work with, please email compliance@dasa.co.uk or call 0800 142 2783 and ask for Charles Kendall, Head of Risk, Compliance and Sustainability.
Employees can also raise concerns under our Whistleblowing Policy. Concerns can be raised anonymously, and nobody will suffer detrimental treatment for raising a genuine concern.
We take every concern seriously, handle it as confidentially as practicable and prioritise the safety of potential victims.
