The transparency rules, introduced in December 2018, require firms to post information on prices, services, details of who would carry out the work and where to bring a complaint.
The sanctions imposed included rebukes and fines of £1,000 and £2,000.
Paul Philip, SRA chief executive, said: ‘People need good information to make good choices.
‘We have provided support for firms to get this right and we will continue to do so. However, I want to be clear that where firms are not providing the type of information that the public expect and our rules mandate, we will take enforcement action. We will continue to check that firms are complying throughout the year.’
