Free Microsoft 365 licence review for UK businesses.
A free 90-minute review of your Microsoft 365 licences by Lanmark, a Microsoft Direct CSP partner. We find where you are over-licensed or exposed and give you a one-page written verdict within five working days. There is no cost and no obligation.
What does a Microsoft 365 licence review do?
It is a structured audit of every Microsoft 365 subscription on your tenant against what your staff actually use. We compare your licence mix (E3, E5, Business Premium, Business Standard, F3 and add-ons such as Defender for Office 365 Plan 2, Entra ID P1 or P2, Intune and Purview) with activity logs and work patterns.
The output is a short written verdict: where you are over-licensed and can save now, where you are under-licensed and exposed, and where the mix is right but the assignment is wrong.
Most small and mid-sized businesses we review show at least one of three patterns: licences still attached to leavers, premium licences assigned by job title rather than by use, and add-ons that duplicate features already in the base licence.
What do we look at in your tenant?
In this order.
- Subscription inventory
- Every active subscription by type, quantity, renewal date and licensed users, cross-checked against your admin centre and billing data.
- Assignment hygiene
- Licences on disabled or leaver accounts, service accounts on full licences, shared mailboxes with paid licences, and group-based rules that have drifted.
- Feature usage
- Activity in Teams, OneDrive, SharePoint, Exchange and Power Platform, plus Defender coverage and Power BI usage against what is paid for.
- Security and governance baseline
- Conditional Access, MFA, self-service password reset, sign-in risk, privileged roles and Purview policies, and whether each gap needs a step up or just configuring.
- Copilot readiness
- Whether your tenant meets the prerequisites and your data sharing is ready. Copilot was priced at £24.70 per user per month in the UK when this review was written, so it matters to get this right.
- Renewal and commercial structure
- Whether annual, monthly or three-year suits your headcount. Often the renewal model itself is the saving.
How much could you save?
We will not put a fixed percentage in writing, because the answer depends on what you have today. Most tenants we look at are over-licensed somewhere, and where that is the case the saving is usually material rather than marginal.
Two patterns drive most of it: premium licences assigned to people who do not use the features, and add-ons bought to fix a problem that a later licence upgrade solved, then never removed. Both are easy to fix once visible. And because the review is free, the downside is small: at worst you get confirmation that you are correctly licensed.
How does the review work?
One 90-minute working session, at your office or on Microsoft Teams.

- Two or three, marked as licensed but unconfigured, or needing a step up.
- Effort and cost
- An indicative line for each recommended change.
Why does a Microsoft Direct CSP do this better?
Many UK businesses buy Microsoft 365 through an indirect reseller, which buys from a wholesaler. Lanmark is a Microsoft Direct Cloud Solution Provider, so we hold the contract directly with Microsoft and are accountable to it for our licensing recommendations.
We see the full price book, and we are bound by Microsoft partner programme conduct rules that prohibit selling licences you do not need. If you are on an Enterprise Agreement, the review also tells you whether it is still the right structure, and a CSP renewal is often cheaper.
The review suits businesses already on Microsoft 365 who want a credible second opinion before a budget cycle, a renewal or a Copilot rollout.

What do people ask about the licence review?
Is the Microsoft 365 licence review really free?
Yes. There is no charge for the 90-minute session, the read-through of your tenant or the one-page written verdict. If you are correctly licensed, the summary says so and the engagement ends.
How long does it take, and does it disrupt the team?
The session is 90 minutes. We need read-only access to billing and licence data in your Microsoft 365 admin centre two days before, which takes about ten minutes to set up. The written verdict follows within five working days. Staff are not affected at any point.
What is the catch?
There is none. Some clients ask us to implement the findings or take over their IT support afterwards. Many take the savings and stay where they are. Both are fine.
Will Lanmark recommend cheaper licences or only upsells?
Both, where the evidence supports it. If a step up makes sense, such as Business Premium where you run Business Standard plus add-ons that duplicate features, we explain why. If a step down makes sense, such as E3 where E5 features are unused, we explain that too.
Can we take the review if we are happy with our current reseller?
Yes. You do not have to move your tenant to Lanmark to receive the verdict, and there is no exclusivity. You can apply the findings yourself or ask your reseller to. If you do want to move billing, see Switch and Save.
