Microsoft 365 alternative

The 123 Reg Microsoft 365 Alternative for UK Businesses

Dead Simple 365 is a direct alternative to 123 Reg for Microsoft 365 Business licences. 123 Reg sells at £7.99 in the first year then renews at £13.99 per user per month ex VAT, in a tenant 123 Reg manages on your behalf. We sell the same licences from £8.83 ex VAT in your own Microsoft tenant, with no teaser price that jumps at renewal.

Operated by Dead Simple Computing Ltd, a UK Microsoft 365 reseller. We resell the same Microsoft 365 Business licences through Microsoft's official partner channel, into a tenant you own.

What 123 Reg actually charges, and the catch at renewal

123 Reg leads with a low first-year price on Microsoft 365 and lets the renewal do the quiet work. The pattern looks like this:

  • Year one: around £7.99 per user per month ex VAT.
  • Renewal: around £13.99 per user per month ex VAT, roughly a 75% jump.
  • The tenant: your licences sit in a Microsoft tenant that 123 Reg owns and administers, not one you control.

The headline number is the bait. The renewal is the real price, and most businesses only notice when the invoice lands a year later. By then the working assumption is that switching means breaking email, so the renewal gets paid and the cycle repeats.

123 Reg versus Dead Simple 365 on price

Here is the same Microsoft 365 Business licence, priced per user per month ex VAT. Microsoft raises its own list prices on 1 July 2026, the first suite increase since 2022, so the table shows both windows.

Business Standard (the usual 123 Reg plan):

  • 123 Reg renewal: £13.99
  • Our Standard now: £8.83
  • Our Standard from 1 July 2026: £9.94
  • Microsoft direct from 1 July 2026: £10.80

Business Premium (security included, which 123 Reg does not sell online):

  • Our Premium now: £15.55
  • Our Premium from 1 July 2026: £15.55
  • Microsoft direct from 1 July 2026: £16.90

On Standard, a 25-seat business on the £13.99 renewal pays £4,197 a year. The same 25 seats with us at £8.83 cost £2,649 a year, about £1,548 less. No teaser price that jumps at renewal. There is no year-two step up from us. If Microsoft changes its list price we tell you before renewal and pass through the real change, and we stay below list on every plan, before and after the July rise.

The provider-managed tenant problem, and how we fix it

A tenant is your own Microsoft 365 organisation account, where your users, mail and data live. With 123 Reg, that tenant is provider-managed, which means 123 Reg holds the administrator role and you rent access to your own environment. That has real consequences:

  • You cannot freely add other Microsoft services or move admin control without going through them.
  • Leaving means untangling a tenant someone else set up and controls.
  • Lock-in is the point, not an accident.

We provision every licence into a Microsoft tenant that you own. You hold the global administrator account. You can add services, change resellers, or leave entirely and keep everything. Your tenant is yours. We just bill you less for the licences in it.

How you move off a 123 Reg managed tenant

Moving off a provider-managed tenant is more involved than a standard licence switch, and we will not pretend otherwise. What happens depends on how 123 Reg set things up.

  • If your mail and data already sit in a tenant tied to your own domain, the work is mostly transferring administrative control and reattaching licences. Your mailboxes, files and Teams stay where they are.
  • If 123 Reg set you up under their own managed structure, a clean migration into a tenant you own is the safer route. Mailboxes, OneDrive and SharePoint content, and Teams data are the items that move.

For anything beyond a simple licence reattach, we offer guided paid migration so the move is planned, not improvised. You keep your domain, your email addresses and your history. We tell you which path applies before you commit, so there are no surprises.

Who should switch, and the one caveat we state upfront

Switching to us makes sense if you are a UK business of roughly 10 to 50 seats that is staring at a 123 Reg renewal near £13.99, wants control of its own tenant, or needs Business Premium for security such as Defender for Business, Intune and conditional access, which 123 Reg does not sell through online checkout.

The honest caveat applies to every Microsoft reseller, including us. Microsoft's New Commerce Experience rules govern subscriptions. You can reduce seat counts only inside the 7 day cancellation window or at renewal, never mid term. Adding seats and upgrading plans works any time. We state this plainly rather than burying it, because it shapes which term suits you. Annual upfront is our lowest price and fixes the rate for 12 months. Monthly flexible costs about 20% more and lets you resize or cancel at each monthly renewal.

Common questions.

Is the Microsoft 365 licence from Dead Simple 365 the same as the one from 123 Reg?

Yes. It is the identical Microsoft 365 Business licence, bought through Microsoft's official partner channel. The difference is the price, the fact that it lands in a tenant you own, and no teaser price that jumps at renewal.

Will switching from 123 Reg break our email?

No. Your mailboxes, files and Teams data stay intact. If you already have a tenant tied to your own domain, the work is mainly transferring admin control and reattaching licences. If you are in a 123 Reg managed structure, our guided paid migration moves your data cleanly into a tenant you own.

Why is 123 Reg cheaper in the first year?

The £7.99 first-year price is an introductory rate. It renews at around £13.99 per user per month ex VAT, roughly 75% higher. We do not run intro pricing. There is no teaser price that jumps at renewal, so you are not signing up to a number that climbs later.

What does a provider-managed tenant mean for me?

It means 123 Reg holds the administrator role over your Microsoft 365 organisation, so you rent access to your own environment and leaving is harder. We provision into a tenant you own and control, so you can add services, change resellers, or leave and keep everything.

Can I reduce my seat count after switching?

Under Microsoft's New Commerce Experience rules, which apply to every reseller, seat decreases happen only inside the 7 day cancellation window or at renewal, not mid term. Adding seats and upgrading plans works any time. We state this upfront so you can pick the right term.

Should I choose annual upfront or monthly flexible?

Annual upfront is our lowest price and fixes your rate for 12 months, which matters with Microsoft raising list prices on 1 July 2026. Monthly flexible costs about 20% more and lets you resize or cancel at each monthly renewal. Pick annual if your seat count is steady.
