How to switch IT support provider without the disruption

Slow responses, surprise bills or a provider who never picks up? Switching IT support is easier than most businesses think - as long as you do it in the right order.

Quick answer

To switch IT support provider: check your notice period, make sure you own the admin accounts for Microsoft 365, your domain and your firewall, choose your new provider, then let them plan the handover - installing their tools, documenting your systems and changing passwords - before your old contract ends. Done properly, your team shouldn’t notice any downtime.

Key takeaways
  • Read your current contract for notice periods and exit terms.
  • Make sure your business - not your IT company - owns key admin logins.
  • Let the new provider run the handover and audit your setup.
  • Change shared passwords once the old provider’s access is removed.

Signs it’s time to change IT support

  • You wait hours - or days - for a response.
  • The same problems keep coming back.
  • You get bills you didn’t expect.
  • Nobody can tell you whether your backups actually work.
  • You’re locked into a long contract for a service that’s slipping.

Step 1: Check your current contract

Find your agreement and look for the minimum term, the notice period and any exit fees. Many IT contracts need 30 to 90 days’ written notice and some auto-renew if you miss the window. Put the date in your diary.

Step 2: Make sure you own your admin accounts

This is the most important step. Your business should hold the top-level access to:

  • Your Microsoft 365 (or Google Workspace) admin account
  • Your domain name and DNS settings
  • Your firewall, router and Wi-Fi
  • Your backups and any cloud services
  • Line-of-business software licences

If your current provider holds these, ask for the details in writing. A good provider will hand them over without fuss.

Step 3: Choose your new provider

Ask potential providers what’s included in the price, how fast they respond, whether there’s a contract and set-up fee, and how they handle onboarding. Local matters too: an engineer who can be on site in a couple of hours is worth a lot on a bad day.

Step 4: Plan the handover

Your new provider should do the heavy lifting. A typical onboarding includes:

  • An audit of your devices, users, licences and network.
  • Installing monitoring and security tools, and removing the old provider’s.
  • Checking backups work and documenting everything.
  • Setting up your team with the new helpdesk.

Step 5: Tidy up access

Once the switch is complete, remove the old provider’s accounts and remote tools, and change any shared passwords they knew. Your new provider can do this for you.

How long does it take to switch?

For most small businesses the handover itself takes days, not weeks. The main timing factor is usually your old contract’s notice period.

Still unsure? Call 01622 677677 - we’re happy to help.

It shouldn’t. A planned handover runs alongside your existing setup, so your team keeps working while the new provider takes over.

Your business owns its systems and data. Ask in writing for all admin credentials. If needed, your new provider can help you recover access to Microsoft 365 and your domain.

No. You just need to give notice in line with your contract.

No. There are no set-up fees and no contracts on our IT support.
