Whether you should hire traders with a Disclosure and Barring Service (DBS) check will depend on the type of work being carried out and the level of access the trader will have to your home or property.
DBS checks, formerly known as CRB checks, are criminal record checks that reveal whether an individual has any convictions or cautions on their record. These checks are commonly required for individuals working in certain professions, such as healthcare, education, or working with vulnerable individuals, where a higher level of safeguarding is necessary.
However, for tradespeople, a DBS check may not always be necessary, especially if they will only be working on your property and not with vulnerable individuals. That being said, if the trader will be working in your home or property unsupervised, it may be prudent to ask if they have undergone a DBS check as a safeguarding measure.
