An expert consultation is not a clinical appointment with a different payer. The client is usually seeking professional insight into an industry, service, technology or market. A doctor's relevant experience may be valuable, but the engagement has different boundaries from patient care.
GLG, Guidepoint and AlphaSights are established names worth investigating in this category. The sensible comparison concerns how experts are identified, which projects match their experience, what work is paid and whether participation is compatible with professional and employment obligations.
This guide reviews public information on 18 October 2026. It does not claim that joining or contacting a network guarantees assignments, a particular rate or a regular monthly income.
Define what you know that a client needs
A useful expert profile is specific. Experience implementing a clinical pathway, using a category of device, managing a service or assessing workflow adoption may be more relevant to a project than a broad statement that you are a doctor interested in health technology.
Describe your role and time period accurately. Distinguish personal experience from information obtained through public reading. A client paying for operational insight should not receive a generic summary presented as first-hand knowledge.
Also define the boundaries. Being able to discuss how a type of service operates does not authorise disclosure of confidential contracts, unpublished results, procurement plans or identifiable clinical information.
GLG: an explicit expert participation route
GLG's expert page describes a route to becoming an expert, setting a rate and being matched with client-selected engagements. It lists several possible formats, including calls and other advisory work.
The important commercial distinction is that registration and a stated rate do not establish utilisation. An expert can have an attractive nominal hourly fee and receive little work if current client needs do not match their experience.
Prepare a concise, accurate profile and respond only to projects you can genuinely address. Treat initial screening as a suitability check, not an invitation to provide extensive free consulting or to exaggerate experience to secure a call.
Guidepoint: assess the actual project and terms
Guidepoint presents an expert-network and research platform. For a clinician approached about a project, the right next step is to understand the specific question, expected interaction and applicable adviser terms.
Ask who is arranging the engagement, how conflicts are checked, what preparation is expected and which time is billable. Confirm payment and cancellation arrangements before reserving a substantial block of time.
This guide does not establish a standard Guidepoint rate or a guaranteed route to assignments for every doctor. Evaluate the opportunity itself rather than rely on an online anecdote from a different profession or country.
AlphaSights: project-led recruitment
AlphaSights' expert information explains that it recruits against client projects rather than operating as a conventional self-sign-up network. Its interest route is directed towards experienced professionals, while specific outreach follows project needs.
That distinction matters for a doctor comparing registration strategies. Keeping a clear professional profile can help the right people understand your expertise, but creating an expression of interest is not the same as receiving an approved engagement.
The published process includes scope and conflict checks. Use them seriously, and confirm the agreed compensation and billable interaction rather than assuming that all preparation, screening or waiting time will be paid.
Calculate effective earnings honestly
Suppose an illustrative agreement pays GBP300 per hour of client interaction. A 45-minute call would generate GBP225 if paid pro rata under those terms. If screening and preparation add another 45 minutes, the overall return is GBP150 per committed hour before tax and costs.
That may still be attractive, but it is not the same as receiving GBP300 for every hour devoted to the opportunity. A cancellation or a lengthy unpaid screening process can change the result further.
Record actual activity over several months. Separate invitations, selected projects, completed work and payments received. One unusually well-paid call is not a dependable annual income forecast.
Check conflicts before the conversation begins
The GMC's conflicts-of-interest guidance provides a professional framework. Also consider employer policies, confidentiality agreements, research commitments and any other restriction relevant to the topic.
A network's compliance process is helpful but does not remove your own responsibility. You may know about a conflict or confidentiality obligation that the intermediary cannot detect from a profile.
Make a clear distinction between general professional experience and information that is confidential or not appropriately available for disclosure. Do not discuss identifiable patients, unpublished trial results, confidential procurement decisions or employer-sensitive material simply because a client asks a well-informed question.
Be willing to stop or narrow the scope
An apparently suitable call can move into an inappropriate area. Agree in advance that you will decline questions outside your expertise or permissions. A clear boundary protects the client as well as the clinician.
A useful response is to explain the limit and redirect to general, publicly available context where appropriate. Do not fill the gap with speculation presented as privileged knowledge.
Afterwards, retain the necessary record of the engagement, agreed fee and payment. Do not keep client-sensitive material merely to build a portfolio example. Public descriptions of past work should respect the contract and the confidentiality of the project.
Distinguish advisory work from patient advice
A commercial client may ask how clinicians generally approach a problem or how a service is adopted. That does not make the call a suitable setting for personalised patient management or an unstructured review of an identifiable clinical case.
Clarify whether the engagement creates any clinical responsibility and whether your indemnity covers the actual work. A project labelled research can still raise professional questions if it moves into specific recommendations outside the agreed scope.
Likewise, a market discussion should not be turned into financial investment advice unless you are appropriately qualified and authorised for that role. Your contribution is the defined expertise you have agreed to provide.
Build a selective portfolio rather than chase every invitation
Expert work can fit well around clinical practice when topics are relevant and interruptions are controlled. It can fit poorly when every invitation requires extensive screening or the clinician feels pressure to speak outside their experience.
Use iatroX's guide to monetising medical expertise to place these calls alongside writing, teaching and more substantial advisory work. The responsibilities and income patterns are not interchangeable.
The strongest approach is to become easy to identify for a narrow set of genuine strengths, maintain professional boundaries and evaluate actual completed work. A rate is only one part of the opportunity; relevance, utilisation and integrity determine the rest.

FAQs
Can any doctor register with all three platforms in the same way?
No. Their approaches differ. GLG describes an expert participation route, while AlphaSights emphasises project-led recruitment rather than a conventional self-sign-up network. Check current requirements and the specific invitation.
Can doctors choose their own hourly rate?
GLG explicitly describes setting a rate, but acceptance and project selection remain separate. For every network, confirm the agreed fee, billable time and terms rather than assuming a quoted rate guarantees work.
Can I discuss my employer's upcoming purchases or unpublished research?
Do not disclose confidential or otherwise restricted information. Check professional, employment and project obligations, and decline questions that cross those boundaries even when the intermediary has completed its own checks.
