Hi Philippa, You could try the Road Haulage Association (www.rha.uk.net). They may be able to advise you on whether they publish some form of safety check list which their members need to meet etc. Alternatively you could check if a given company is listed in the RHA Online Directory (https://www.findahaulier.co.uk). It's not a firm guarantee of safety compliance, but my understanding is that a company has to be an RHA member before it can join the directory.
