What Happens to Your IT When Your Business Moves Office
What Happens to Your IT When Your Business Moves Office
An office move feels like a logistics problem. Boxes, furniture, change of address forms.
For your IT setup, it is something more disruptive than that. Almost everything about how your technology works is tied to a physical location in ways that are easy to underestimate until the move happens.
Here is what actually changes when your business moves, what tends to get lost in the process, and how to plan for it before you hand back the keys to the old space.
Your Internet Connection
The internet connection at your new office is not automatically sorted just because you signed a lease. ISP availability varies significantly by building and location. The provider that served your old office may not serve the new one, or may offer significantly different speeds or pricing.
Check this before you sign the lease if possible, not after. Some buildings have existing infrastructure contracts that limit your options. Others have fibre already run to the floor. Finding out which situation you are in before you commit saves time and occasionally changes the decision about the space.
Allow more lead time than you think you need. Business internet installations frequently take longer than quoted, and being dependent on a 4G backup connection for the first two weeks of a new office is avoidable with enough notice.
If your current setup uses a static IP address for any reason, such as for remote access to internal systems or for whitelist-based access to third-party services, a new internet connection means a new IP address. Make a list of anywhere your current IP is registered or whitelisted before you move so you can update those after.
Your Network Infrastructure
The router and network equipment at your current office belongs to either you or your current ISP or landlord depending on how it was set up. Know which before you move.
If you own your networking equipment, it comes with you. If it was provisioned by the ISP, it stays. If it was installed by a landlord as part of a serviced office arrangement, definitely stays.
Any network equipment you bring with you will need to be reconfigured for the new internet connection. WiFi networks, VLANs, firewall rules, DHCP settings. If your IT provider set this up and documented it, the reconfiguration is straightforward. If it was set up years ago by someone who is no longer around, the move is an opportunity to discover what you actually have and get it documented properly.
Wired networking in the new space is worth thinking about early. Many offices have existing cabling that may or may not suit your layout. If you need new cabling runs, these need to be booked and done before you move in, not after everyone is sitting at their desks wondering why the connection is unreliable.
Your Phone System
If your business uses a traditional phone system tied to physical lines, moving is significantly more complex than if you are on a cloud-based VoIP system.
Traditional lines need to be ported or new lines installed at the new address. This takes time and involves the phone carrier. Porting a number to a new address is not always straightforward and sometimes involves a new number entirely depending on the exchange.
VoIP systems move easily because they are not tied to a physical line. The phone works wherever there is an internet connection. The main consideration is making sure the new internet connection has adequate quality of service for voice calls, which is usually a configuration question on the router.
If you have a business phone number that appears on your website, your Google Business profile, and your marketing materials, protecting that number through the move matters more than the technology behind it.
On-Premise Servers and Equipment
If your business has servers, network-attached storage, or other infrastructure physically located in the current office, the move requires planning well in advance.
Physical servers need to be shut down properly, transported carefully, and brought back online in the correct sequence at the new location. If the server was set up to expect a specific network configuration, that configuration needs to be recreated or updated.
The move is also a natural audit point. Equipment that has been running quietly in a cupboard for five years warrants a look before it gets packed into a van. Is it still needed? Is it under warranty? Is it documented?
If you use ExplainMyIT's on-premise network monitor, run a scan before the move and save that report. It gives you a clean baseline of everything on your current network that you can compare against after the move to confirm everything came across correctly.
Access to Cloud Systems
Cloud systems do not move with you physically, but the way you access them might change.
If any of your cloud services use IP-based access controls, your new internet connection's IP address will need to be added to those allowlists. This includes things like accounting software with IP restrictions, remote desktop services, or cloud infrastructure management panels.
VPN configurations that reference the office network may need updating. Remote employees or branches that connect to your office VPN will need updated connection details.
Your Address Across Everything
The administrative side of an office move generates a longer list than most business owners expect.
Accounts that need your address updated include: domain registrar contact details, hosting account billing address, Google Business Profile, Companies House or provincial business registry, bank accounts, insurance, HMRC or CRA, email marketing platforms, payment processors, and any subscription services that send physical mail.
Missing one of these is low stakes in most cases. Missing the domain registrar contact or the billing address on a hosting account is less low stakes if it causes a failed payment or missed renewal notice.
What Gets Lost in Office Moves
The most common IT casualty of an office move is not equipment. It is documentation and institutional knowledge.
The move creates activity and distraction. In the middle of it, things get done quickly without being written down. The new network gets set up without the configuration being documented. A temporary workaround becomes permanent. Someone sets up the printer with their personal account because it was faster and nobody updates it later.
Six months after the move, the question is: does anyone know how the network is set up? Where the server backup is stored? Who the ISP contact is for the new connection?
The move is an opportunity to establish a clean documented baseline for your new setup. It is worth treating it that way rather than just getting everyone connected as fast as possible and moving on.
A Practical Timeline
Six to eight weeks before the move:
Confirm ISP options and place the order for your new internet connection. Check whether a static IP is needed and whether porting it is possible. Inventory any physical IT equipment that is moving.
Three to four weeks before:
Confirm the installation date for the new internet connection. Plan the network configuration for the new space. Book any cabling work that needs to happen before move-in.
One to two weeks before:
Run a full scan of your current network if you have on-premise monitoring. Back up anything stored locally. Confirm the plan for physical equipment transport.
Moving day and the week after:
Bring the new connection online and test it before physical equipment arrives if possible. Reconnect and test equipment in sequence. Update IP allowlists and VPN configurations. Confirm phones are working.
Within the first month:
Update your address everywhere it appears. Document the new network configuration while it is fresh. Confirm monitoring and backups are running correctly in the new environment.
FAQ
Do we need new IT support for the move or can our existing provider handle it? Your existing IT provider should handle the move if they are managing your systems already. If they are not actively involved in your day-to-day IT, the move is a good opportunity to engage someone for the transition. An unmanaged move of a complex setup creates problems that surface weeks later.
We are moving to a serviced office with shared IT. What changes? Quite a lot. In a serviced office the network infrastructure is usually managed by the building. You connect your devices to their network rather than running your own. This is simpler in some ways but means you have less control over configuration and potentially less visibility into what is on the network. If you have security requirements or run on-premise systems, confirm with the serviced office provider what level of customisation is available before signing.
Can we use the downtime of the move to upgrade our IT setup? Yes, and the move is often a natural trigger for upgrades that have been deferred. New cabling, upgraded networking equipment, migration from a local server to cloud storage. The disruption of the move makes it easier to absorb additional changes than doing them at an arbitrary time during normal operations. Plan any upgrades as part of the move rather than as separate projects.
We use ExplainMyIT's network monitor. Do we need to do anything for the move? Run a scan before the move and note what is on the current network. After the move and once everything is reconnected, run another scan. The comparison will show you what transferred correctly and flag anything unexpected on the new network. The agent itself moves with the machine it is installed on and will reconnect automatically once the new internet connection is live.
An office move changes your network, your ISP, your physical infrastructure, and in some cases your phone system. ExplainMyIT's monthly external snapshot will automatically reflect your new configuration once DNS and other external records are updated. If anything in your public setup changes during or after the move, you will see it in the next report.
See what your current setup looks like before the move so you have a clean baseline to compare against after.
