Introduction
An office move feels like a purely logistical exercise until you get close to the date and realise how dependent the entire business is on IT, connectivity and telephony. For SMEs in the 50–150 user range, IT is the foundation everything else sits on. If it isn’t planned early and handled carefully, even a well organised move can stall because the internet isn’t live, the Wi Fi doesn’t reach key areas, the phones won’t port, or staff arrive on day one with systems that simply don’t work.
The good news is that these risks are predictable and avoidable with the right timeline.
The short answer
Start planning your connectivity and core IT at least 8 to 12 weeks before the move. Confirm internet lead times, design Wi‑Fi properly, plan telephony and number porting, and prepare a clear cutover weekend plan so day one in the new office feels calm rather than chaotic.
Why IT planning gets left too late (and why it causes the biggest disruption)
In most office moves, the workstreams with the biggest consequences are the ones people assume will “just work” on the day. Leadership concentrates on leases, costs, furniture and layouts. Operations focus on logistics. Facilities teams think about access, signage and health and safety. IT then gets pulled in at the final stages with a simple question: “Can we have everything live for Monday?”
What often gets missed is that connectivity and IT have real‑world lead times. Internet provision is dependent on providers, site surveys and capacity. Wi‑Fi coverage can’t be guessed. Telephony migrations require sequencing. And even something as simple as cabling can introduce delays if it’s only considered late in the process.
The risk isn’t that IT people can’t work quickly. It’s that some things physically cannot be rushed.

The 8–12 week timeline: what to focus on and when
The most successful office moves follow a clear order. You don’t need a heavy project plan, but you do need the big decisions made early enough that they can be executed without panic.
Weeks 8–12: Secure your connectivity and infrastructure basics
This is the point where the most impactful decisions are made. Check which internet options are available at the new site. In some locations, business‑grade FTTP or fibre is readily available whereas in others, a leased line may need provisioning, which can take longer. Even if the office has an existing line, you may need to reconfigure, transfer or upgrade it.
This is also when you should think about your fallback plan. A temporary 4G or 5G solution can provide resilience, but it must be tested properly. Too many SMEs assume a mobile backup will save them, only to discover it can’t handle their workload.
Weeks 6–8: Plan Wi‑Fi coverage and internal networking
Wi‑Fi design is often rushed or guessed, but coverage and performance depend on more than simply putting access points in hallways. Building materials, layout, room density and device load all matter. If your Wi‑Fi struggles on day one, productivity drops immediately, so it’s worth getting this right.
You’ll also want to confirm switching, cabling and any changes to your network layout. Moves are a natural point to tidy up legacy infrastructure that has outgrown the old office.
Book a WiFi Survey
Ensure fast, reliable wireless coverage with a professional WiFi survey. Identify issues, optimise performance and plan access point placement with confidence.
Weeks 4–6: Telephony, Teams Voice and number porting
Phone systems can cause hidden disruption. Number porting can take time, Teams Voice migrations require testing and contact flows need planning. You want to avoid the situation where calls work on one system but not another, or where customers reach the wrong place on day one.
If you’re modernising your phone system at the same time as the move, treat it as a mini‑project. A well‑designed call flow, tested early, can reduce chaos dramatically.
Weeks 2–4: Devices, access and day‑one setup
This is when you align user needs with the new environment. Confirm where printers go, how meeting rooms are equipped, where docking stations and monitors will be placed, and how teams will work on day one. It sounds small, but it is the difference between a productive first day and a room of people waiting for someone to “fix the tech”.
Cutover weekend: a calm, choreographed sequence
A well‑executed move has someone on-site to test connectivity, Wi‑Fi coverage, internal routing, meeting room tech, telephony, and any critical apps. The goal is not perfection but predictability. You want staff walking in on the Monday morning to a working environment rather than a queue of avoidable issues.
Common mistakes most SMEs face during an office move
Most office move problems are not technical, they are timing-based or assumption-based. We see the same patterns come up again and again.
Many businesses assume internet will be live because the provider “booked an install date” but installs can slip, especially in multi-tenant buildings. Some teams assume Wi‑Fi will behave the same way it did in the old office, even though the building layout is completely different and number porting is often left just a little too late, causing missed calls as systems transition.
Moves also reveal hidden IT debt. Old servers that should have been retired years ago become fragile when relocated. Forgotten switches emerge from cupboards. Legacy devices that worked “as long as nobody touched them” stop responding once unplugged.
None of these problems are inevitable. They just need space in the timeline.
A move is not just a relocation. It’s an opportunity.
Office moves naturally surface questions about how IT is structured and it is often the perfect moment to retire legacy kit, standardise devices, consolidate licensing, rationalise SharePoint or replace inconsistent telephony. Moving offices forces the environment to be rebuilt in some way, so it’s often the cheapest and easiest time to improve it (although we appreciate that can add cost to an already expensive time).
You don’t need to overhaul everything. You can simply ensure that what moves with you is fit for the next few years rather than a continuation of decisions made long ago.
An example scenario that shows the difference planning makes to bring it to life
A 100‑user construction consultancy moved offices after outgrowing their space. They assumed the internet line would be live because it had been ordered early, but the installation slipped due to survey issues, leaving them with no primary connectivity two weeks before the move. Fortunately, they had begun planning early enough that they could deploy a temporary 5G solution, test it properly and ensure it could support Teams calls during the first week.
During the readiness work, they also discovered the old Wi‑Fi layout would not support the new building. Rather than copying it across, they redesigned coverage and avoided the “meeting rooms don’t work” issue that many firms experience.
The move wasn’t just smooth; it became the moment they standardised devices, improved patching and shifted to Teams Voice with clearer call routing. The office move was a disruption, but it became a positive one.
FAQs
How early should IT planning start for an office move?
At least 8–12 weeks before moving. Connectivity lead times, number porting and Wi‑Fi design all take time.
Can we rely on temporary internet while waiting for a line?
Yes, but only if it’s tested properly. A 4G or 5G backup is useful, but capacity varies and shouldn’t be assumed.
What causes most office move IT failures?
Late planning, incorrect assumptions about connectivity, rushed Wi‑Fi design and number porting delays.
Should we upgrade systems during the move?
Often, yes. It’s the least disruptive time to modernise telephony, tidy infrastructure or improve security baselines.
Do we need IT on-site during the cutover?
It’s highly recommended. Issues that take minutes to fix on-site can take hours or days if discovered later.
