RentalsGraph Certification

How the assessment works

What we check, where the evidence comes from, how the score and the rating are calculated, how often they are renewed and how a business can correct an error.

Three different things

Business access
Confirms that a person may manage a business profile. It does not check the business and is not a certification.
Verified business facts
Individual facts (for example a phone number or a rental terms page) that RentalsGraph found independently. A fact the business only typed in is shown as "Provided by the business" until it is checked; a value the business changes is checked again.
Certification
A paid programme: the business is assessed against the criteria below, reassessed every month, and receives a public profile and a website badge. Paying activates the assessment; it does not buy a rating.

The assessment covers how clearly and verifiably a business publishes key information. It does not assess vehicles, service quality, safety, prices charged to customers or legal compliance, and it is not a review score.

How the score and the rating are calculated

  1. Overall score (0-100) = weight of the checks the business meets / weight of the checks that could be assessed x 100. A check that cannot be assessed yet is left out; it is not counted as failed.
  2. Base rating (1-5): the score is placed in fixed bands - below 40: 1.x, 40-55: 2.x, 55-70: 3.x, 70-85: 4.x, 85 and above: 5.0 - and interpolated inside the band to one decimal.
  3. Customer-rating lead: when the business's public customer rating leads the median of comparable businesses in its market, up to +0.5 is added (at least 30 ratings and at least 3 comparable businesses are required). It never lowers the rating.
  4. Certification rating = base rating + customer-rating lead, at most 5.0.
  5. Publication: the rating is shown on the public profile and the badge from 4.0/5. Below that, the certified mark stays and the exact rating is shown only to the business in its workspace.

How often, and how errors are corrected

  • Every business with an active Certification is fully reassessed once a month.
  • When a business changes a fact in its workspace, that fact is checked straight away and the rating is recalculated.
  • A check that cannot be completed (for example the website does not answer) is shown as "Could not check" and is not a finding against the business.
  • To report an error, write to support@rentalsgraph.com with the business name and the fact concerned.
