Word, Excel & PowerPoint

Desktop, web and mobile — same experience on the train as at the desk.

Why it matters: no retraining. Your team opens the file and gets on with it.

Business email & calendars

Outlook + Exchange, shared calendars, custom domain email, distribution lists.

Why it matters: professional email your clients trust. 50 GB mailboxes.

Teams chat & meetings

Video calls, screen share, persistent chat — client communication in one place.

Why it matters: no more shadow WhatsApp groups for client work.

OneDrive & SharePoint

1 TB of secure cloud storage per user, versioned, with granular sharing controls.

Why it matters: file-server retirement, fee-earners offline-ready.

Device management (Intune)

Laptops, phones, tablets — enrolled, policy-controlled, wipe-on-loss.

Why it matters: a stolen partner iPad no longer means a breach notification.

Advanced threat protection

Microsoft Defender for Office 365 + Defender for Business against phishing and ransomware.

Why it matters: the attacks actually aimed at small firms these days.

Identity with Entra ID P1

Why Business Premium

More productive people, better-protected firm.

Joined-up working

Email, calendars, meetings, calls, documents and collaboration in one connected Microsoft environment.

Hybrid by design

Built for secure remote and hybrid working without making everyday work harder than it needs to be.

Protects client data

Classification, encryption and DLP reduce the risk of sensitive information being seen by the wrong eyes.

Simpler IT

One platform, one licence, one invoice — instead of separate tools for productivity, email, files, security and devices.

Scales with you

More users, more devices, more compliance expectations — the platform grows with you, not against you.

Better-supported users

Fewer "have you tried turning it off" moments, more "all sorted, back to work". Staff-rated support > 4.8/5.

FAQ

The questions partners always ask us first.

Which licence do our people actually need?
For most professional firms: Business Premium. It combines productivity, email, devices, security and identity in one licence. We size it properly at review and tell you if a mix of plans saves money.
How much downtime during migration?
Typically none during working hours. We cut over on an evening or weekend, pre-stage mailboxes and files, and on-site for go-live morning.
How do you roll out MFA without enraging staff?
Group by group, communicated two weeks ahead, with app-based MFA as default and registered hardware tokens for people who dislike phones. We've done this 200+ times.
Is my data kept in the UK?
Yes. Your Microsoft 365 tenant is pinned to the UK data residency region, and all HDUK-managed infrastructure is hosted in UK datacentres.
What if we want to cancel?
Monthly M365 licences are cancellable monthly. Annual licences honour the annual commitment. HDUK management contracts are 30 days' notice after the initial term.
What are your support SLAs?
Critical (firm-down): response 15 min, target fix 2 h. High (user group): response 30 min. Normal: response 2 working hours. Real humans, UK-based, named engineer assigned.
