How to choose a clinic (2026)

Advice about picking a clinic is usually someone's opinion. This page is counts instead: what 510 real clinics actually publish about themselves, and what that means when you compare two of them.

What to check, and how often it is published

CheckListings with itWhy it matters
A live website 510 (100%) Open it before you plan anything. A dead link usually means the business has moved on.
A street address 444 (87%) A published address means you can visit, and it is what map apps need.
A phone number 433 (85%) The fastest way to confirm anything that matters before you go.
A list of services 510 (100%) Tells you what they actually do, instead of what the name suggests.
Opening hours 272 (53%) If hours matter to you, confirm them before you travel.
A price 14 (3%) Many in this trade quote per job, so a published price is worth noting when you see one.

Before you commit

  1. Open the business's own website from its listing here, and check the page is still live.
  2. Compare two or three on the same points. Save the ones you like and put them side by side.
  3. Confirm price and hours with the business directly. 3% publish a price and 53% publish hours, so most of this has to be asked.
  4. Check the date on the listing. Each one shows when it was last checked against the business's own site.
