Choosing a Dental Marketing Agency in London: 8 Questions to Ask

There are more dental marketing agencies in London than there are good ones. The category has grown rapidly in the last five years as private dentistry has expanded, and the gap between agencies who genuinely move the needle and agencies who collect retainers has widened significantly. If you are choosing an agency for your practice, the cost of getting it wrong is not just the wasted retainer. It is the opportunity cost of a year not spent winning patients.

This is a practical checklist of eight questions that will tell you in 30 minutes whether an agency is worth working with. Run through them in any pitch meeting. The answers will tell you more than any case study deck.

1. "Show me three London dental practices you currently work with."

Not "have worked with". Currently work with. Active retainers. Live websites you can visit and social profiles you can scroll.

If the agency cannot name three current dental clients in London, you are looking at a generalist who has done dental work occasionally. The dental sector has specific quirks (GDC compliance, treatment-led search behaviour, the consultation funnel) that take years to learn. An agency without an active dental book will charge you to learn on your project.

Ask to speak to one of the three named clients before signing. A confident agency will arrange this readily. An evasive agency will hesitate, suggest "client confidentiality" issues, or offer a different reference. That hesitation is your answer.

2. "What is your typical cost per consultation booking for a London private dental practice?"

A capable dental marketing agency knows this number off the top of their head, by treatment category, with seasonality variation. Expect a range. For Invisalign in central London, expect £150 to £400 per booked consultation across paid channels. For implants, £200 to £600. For composite bonding, £80 to £250.

If the agency cannot give a number, they have not built the tracking infrastructure to measure it. If the number is implausibly low, they are either operating in a less competitive market or using attribution that overstates results.

The right answer comes with caveats: "in our current book it ranges from X to Y depending on practice maturity, location, and treatment focus. Newer practices typically see Z in the first three months and then settle to W."

3. "What conversion tracking do you set up, and who has access to it?"

The right answer covers Google Ads conversion tracking for forms, calls, and bookings; Google Analytics 4 with proper event configuration; call tracking for older patients who phone rather than fill in forms; and CRM integration so consultations attended are visible at the campaign level.

Crucially, the practice should have direct access to all dashboards. If the agency owns the Google Ads account, the GA4 property, and the call tracking system in their own login, you have lost leverage. When the relationship ends, they keep the data and the conversion history.

Insist that the dental practice owns every account. The agency is granted access. Not the other way around.

4. "Show me the work itself, not the strategy slides."

Agencies will pitch with strategy slides, frameworks, and case study summaries. The work is downstream of the strategy. Ask to see the actual outputs: live treatment pages they have built, real Reels they have produced, real Google Ads accounts they have run, real review profiles they have grown.

A serious agency can show you the work because they have done the work. An agency selling strategy without real outputs is selling consulting hours, which is fine if that is what you want, but most practices are looking for delivery.

Look for output quality. Are the treatment pages well written, with the depth and pricing transparency that ranks? Are the Reels watchable, with the right pacing and clinician on camera? Are the Google Ads landing pages built for conversion, or are they sending traffic to a generic homepage?

5. "Who will actually do the work?"

The senior pitch team in agency meetings is rarely the team that will run your account. Ask explicitly: who will be writing the content, running the ads, managing the social media, producing the Reels, and handling client communication?

The right answer names specific people, gives their experience, and ideally introduces them in the pitch process. The wrong answer is generic: "our content team", "our paid media specialists". When the same answer is given by every agency, it means the actual delivery is being done by junior team members or outsourced overseas.

This is the question that exposes the gap between marketing and delivery in agency land. Be ruthless about it.

6. "What is your contract length and notice period?"

Dental marketing programmes need 4 to 6 months to show meaningful results, particularly when SEO and content are involved. Six-month minimum terms are normal and reasonable.

Twelve-month locked contracts with no notice period are a red flag. Contracts that auto-renew unless you give 90 days' notice are a red flag. Contracts that retain ownership of accounts, content, and creative on termination are a serious red flag.

Reasonable terms: 6-month initial term, monthly thereafter, 30 days' notice, all accounts and creative owned by the practice, a clean handover process documented in the contract from day one.

7. "How will you brief the clinicians for content?"

Most dental marketing failures start here. The agency does not have a system for briefing clinicians, which means content gets written by people who have never set foot in a dental surgery, mistakes get made, and the clinician gets frustrated.

A good agency will visit the practice, interview the clinical team, photograph the surgeries, build a content calendar around real cases, and run brief monthly content review meetings with the clinicians. Bad agencies will do none of this and produce generic content that could be for any practice in the country.

Ask to see the briefing process. Ask how often the agency visits in person. Ask how they handle clinical accuracy review.

8. "What does success look like at month 3, month 6, and month 12?"

The agency should give specific numbers. At month 3, expect [X] booked consultations from paid channels and clear ranking improvements on [Y] keywords. At month 6, expect total enquiry volume to be Z percent higher than baseline. At month 12, expect SEO to be producing [N] consultations per month.

Vague answers ("we expect strong growth", "results will compound") mean the agency has not done the modelling. Specific numbers, with caveats and assumptions, mean the agency has thought about your business.

If the numbers turn out to be wrong, that is fine. Marketing is full of variables. What matters is that the agency was willing to commit to a forecast and is willing to be measured against it.

What good looks like

A good dental marketing agency in London will: have an active book of dental clients you can speak to, give specific numbers on cost per consultation, set up conversion tracking owned by the practice, show real work rather than strategy slides, name the actual delivery team, sign a fair contract, brief clinicians properly, and forecast success with specifics.

This list is not exhaustive but it will filter out roughly 80 percent of agencies you might consider. The 20 percent that pass are the ones worth working with.
