Your enquiry form should be as short as it can be while still letting your team reply well. For most clinics, that means three to five fields, plus a consent checkbox. There is no magic number, though, because every extra field adds effort and may raise a privacy worry. This guide gives a direct answer, then walks through each common field and explains whether to keep it, make it optional, or leave it out.
The Short Answer
Start with a minimal form.
- Name
- One way to reach the patient, such as a phone number or an email address
- Treatment of interest, chosen from a short list
- An optional message box
- A consent checkbox for the privacy notice, and a separate, unticked box for marketing
That’s four or five fields. Then add a field only when you can name a clear reason why you need it at this stage, and when its value outweighs the friction it adds.

The Rule Behind the Answer
Ask yourself one question for every field: “Do we need this to reply to the first enquiry?”
- If yes, keep it.
- Information that would only be nice to know should be optional, or dropped.
- Anything you can collect later belongs in a secure system, after the first reply.
The first enquiry has a simple job. It starts a conversation. Your team can gather the rest on the phone, at the consultation, or in a secure patient form after the person books.
Why Fewer Fields Usually Help
Short forms tend to feel easier, and that matters most on a phone.
- Typing on a small screen is slow, so each field costs effort.
- Long forms feel like commitments, so hesitant visitors leave.
- Each extra field gives people another chance to wonder why you’re asking.
- Errors multiply with more fields, such as a mistyped postcode.
However, the effect varies by clinic, audience, and traffic source. So treat any quoted statistics with caution, and test your own form. We cover testing below.
A Field-by-Field Guide
The table below gives a starting recommendation. Adapt it to your clinic and local rules.
| Field | Recommendation | Why |
|---|---|---|
| Name | Keep | You need to know who to reply to; one field is enough |
| Phone number | Keep one contact method; let patients choose | Some prefer calls, and others prefer email |
| Email address | Keep one contact method; let patients choose | Useful for confirmations and written details |
| Treatment of interest | Keep as a short dropdown or tick list | Helps you route and prepare the reply |
| Message | Optional | Lets patients ask a question in their own words |
| Preferred contact time | Optional | Helpful if you’ll phone back |
| How did you hear about us | Optional, or track another way | Useful for marketing, but not needed to reply |
| Date of birth | Leave out at this stage | Collect at registration if required |
| Home address | Leave out | Not needed for an enquiry |
| Medical history | Leave out of open forms | Sensitive; collect in a secure patient system |
| Photo upload | Leave out unless a secure process exists | Sensitive, and a privacy risk |
| Consent boxes | Keep: privacy notice required; marketing optional | Clear, separate consent builds trust |
The Fields in More Detail
Name
One field is usually enough. A single “Name” box is simpler than separate first and last name fields. Make sure it accepts long names, hyphens, and accents.
Phone number and email
Many clinics require both. However, requiring only one reduces friction. Let patients pick the way they’d like to be contacted, and make that one field required. Show a short line explaining how you’ll use it, such as “We’ll only use this to reply to your enquiry.”
Use the right keyboard type on phones. For instance, a number pad appears for phone numbers when the field is set up correctly.
Treatment of interest
A short dropdown or a set of tick boxes works better than a free-text box. It helps your team prepare, and it saves patients from typing. Include an option such as “Not sure yet”, so people don’t feel forced to choose.
Message
Make it optional. Some patients want to ask a question, and others don’t. Add a gentle prompt, such as “Anything you’d like us to know?” Don’t invite detailed medical descriptions. A short note can help: “Please don’t include medical details here. We’ll discuss them at your consultation.”
Preferred contact time
This field helps when you plan to call. Keep it optional, and offer simple choices such as morning, afternoon, or evening.
How did you hear about us
This question helps your marketing, but it isn’t needed to answer the enquiry. Make it optional, or capture the source automatically through hidden tracking fields. Our post on tracking bookings by traffic source explains how.
Date of birth, address, and identity details
Leave these out of the first enquiry. If your treatments have age limits, ask your adviser how to handle age checks. Some clinics confirm age at the consultation instead of in the form, or use a simple confirmation box. Rules vary, so get advice.
Medical history
Never collect medical history in a general enquiry form. These details are sensitive, and a patient may not trust a short web form with them. Collect them later, in a secure patient system, after the person becomes a patient.
Photo uploads
Skip them unless you have a secure, approved process and a clear legal basis. Photos of skin or faces are personal and can reveal health information.
Consent boxes
Show two separate items.
- A required acknowledgement that links to your privacy notice.
- An optional, unticked box for marketing messages.
Never pre-tick the marketing box, and never make it a condition of getting a reply. Our post on email newsletters explains consent in more detail.
When a Longer Form Makes Sense
Sometimes more fields are justified.
- Online booking: You need a date, a time, and a service.
- Deposit or payment steps: You may need billing details, handled through a secure payment provider.
- A patient registration form: This comes after the booking, in a secure system, and may ask for health information.
- A specific campaign: A tightly targeted offer may need one extra qualifying question, such as the area they live in.
Even then, keep each step short, and explain why you’re asking.
Split Long Forms Into Steps
If you must ask more, use a short multi-step form.
- Ask for the essential contact details first.
- Show a progress indicator, so people know how much is left.
- Put the easiest questions first.
- Let people go back without losing what they typed.
- Save the first step, so you don’t lose the contact if they stop.
Be careful with that last point. Saving partial entries raises privacy questions. Tell people what you do, and check your consent rules.
Make Each Field Easy
Good design lowers friction.
- Put labels above the fields, not inside them, since labels inside vanish when people type.
- Use clear, plain wording.
- Mark required fields clearly, and keep them to a minimum.
- Support autofill, so phones can complete names and numbers.
- Show helpful error messages next to the field.
- Make buttons and fields large enough to tap.
- Make the form work with keyboards and screen readers.

Test Your Own Form
Because audiences differ, test what works for your clinic.
- Record a baseline. Note the form start rate and the completion rate. Our post on tracking website visitors explains how to set up form events.
- Make one change, such as removing a field or making one optional.
- Wait a few weeks, so you collect enough submissions to compare.
- Compare the completion rate. Also compare the quality of enquiries, because a shorter form may bring more enquiries but less detail.
- Decide, and keep notes.
If your traffic is small, make a clear, sensible reduction and compare before and after. Our post on website conversion rate explains how to read the numbers fairly.
Don’t Forget the Follow-Up
A short form puts more weight on your reply process.
- Reply within a few hours during opening times.
- Ask the extra questions on the phone or at the consultation.
- Send an automatic confirmation, so people know their message arrived.
- Offer a secure link for the longer registration form after they book.

Privacy and Rules
Clinic forms collect personal data, so extra care is needed.
- Follow the data protection and marketing consent rules in your region.
- Collect the minimum personal information you need.
- Gather health information only through secure, approved systems.
- Keep names, contact details, and health details out of analytics, page addresses, and event labels.
- Check how your form tool stores and shares data.
- Limit staff access, and remove it when people leave.
- Follow your regulator’s rules on advertising treatments and handling enquiries.
- Never give personal medical advice in replies. Invite people to book a consultation instead.
Rules vary by country. Ask a qualified adviser to review your form.
Common Mistakes
- Copying a long form from another system. Many include fields you don’t need yet.
- Requiring both phone and email. One is enough to reply.
- Asking for medical history up front. This feels intrusive and risks privacy problems.
- Using free-text boxes for everything. Dropdowns are easier on phones.
- Hiding errors. People can’t tell what went wrong.
- Pre-ticking marketing boxes. This breaks trust and may break rules.
- Never testing the form. Silent failures cost enquiries.
- Cutting so many fields that you can’t reply. You still need a way to reach the patient.
A Simple Starter Form
Here is a clear template you can adapt.
- Name
- How would you like us to contact you? (Phone or email, with one field for the details)
- Which treatment are you interested in? (Short list, including “Not sure yet”)
- Anything you’d like us to know? (Optional, with a note not to include medical details)
- A required privacy acknowledgement, with a link to your notice
- An optional, unticked box for marketing messages
- A button that says “Request a consultation”, with a line about your reply time
The Takeaway
Your enquiry form should usually have three to five fields, plus a consent checkbox. Keep what you need to reply, make useful extras optional, and leave out sensitive details such as medical history, photos, and identity data. Collect more later, in a secure system, after the person books. Then test your own form, reply quickly, and follow privacy and advertising rules. A short, clear form helps hesitant patients take the first step.
