One of the first questions facilities managers ask is, "how long will it take?" The reality is that an office refurbishment will take anywhere from a few weeks to several months, depending on the size of the workspace and the complexity of the works. A light refresh might be completed in four to six weeks, while a full fit-out involving HVAC, structural works, and new layouts could stretch to half a year.

But it isn't just about construction. A big part of the office refurbishment timeline comes from planning and approvals, design development, procurement, and the final handover. If you're responsible for a refurbishment project, you'll want to know not only how long your office refurbishment will take but also how long the office could be out of action.

What Counts as an Office Refurbishment?

Office refurbishments vary widely in scope. Some are cosmetic updates: repainting, new flooring, upgraded lighting, and refreshed furniture. These can often be done while the office stays in use.

Others are moderate refurbishments, involving changes to layout, new partitions, and adjustments to M&E systems. These take longer and may require phasing around staff.

At the top end are full renovations or fit-outs. These involve stripping the office back to its shell, installing new HVAC and electrical systems, and rebuilding with new finishes and furniture. Projects of this scale usually require the office to be vacant until completion.

How Long Do Different Refurbishments Usually Take?

  • Cosmetic refresh (carpets, paint, lighting): 4–6 weeks
  • Moderate refurbishment (partitions and services upgrades): 8–12 weeks
  • Major fit-out (structural works and new M&E systems): 12–24 weeks or more

To give examples: a 5,000 sq ft workspace in central London that needed new flooring, lighting, and a reconfigured breakout area took seven weeks from strip-out to handover. By contrast, a 20,000 sq ft open-plan office in Reading, refurbished with new HVAC and partitioned meeting rooms, ran for twenty-two weeks, plus another eight weeks of design and approvals before work began.

How Long Could Your Office Be Out of Action?

How long your office refurbishment disrupts business depends on scale and phasing. Light refurbishments can often be done during evenings or weekends, with staff still working in the space. Moderate refurbishments are usually phased so parts of the office remain open, though productivity may dip as people move around the floor.

Full fit-outs or major renovations almost always mean a temporary relocation. In these cases, the office might be closed for two to three months while works are carried out. Planning this early — swing space, remote working, or a temporary relocation — makes disruption easier to manage.

The Main Stages of an Office Refurbishment Timeline

  1. Assessment and planning (2–4 weeks) — Objectives agreed, budgets set, stakeholders consulted.
  2. Design and planning (4–8 weeks) — Layouts, specifications, and finishes developed.
  3. Approvals (3–6 weeks) — Landlord consent, Building Control, and fire safety checks. A common source of delay.
  4. Procurement and mobilisation (2–4 weeks) — Orders placed for furniture and finishes, labour scheduled, site preparation.
  5. Strip-out and preparation (1–2 weeks)
  6. Construction (4–12 weeks+) — Depending on complexity.
  7. Finishes (2–4 weeks) — Flooring, ceilings, lighting, and furniture.
  8. Inspection and snagging (1–2 weeks) — Walkthroughs, testing, and adjustments.
  9. Handover — Completed workspace returned to client.

The full office refurbishment timeline — from first drawings through to inspection, snagging, and handover — can take three to nine months.

Why Some Projects Take Longer

Several factors influence how long an office refurbishment takes. Complexity is the first: structural works, specialist finishes, or new HVAC systems add time. The existing condition of the office is another — outdated electrical or plumbing systems may need upgrading.

Approvals are a common source of delay, as are late design changes. Lead times for imported materials or bespoke furniture can also slow progress. And when refurbishments are carried out in occupied offices, the need for phasing and restricted working hours often means the programme will take longer than if the space were vacant.

  • Complex designs or structural works
  • Hidden issues with existing services such as HVAC or electrics
  • Slow approvals from landlords or regulators
  • Late design or layout changes
  • Long lead times on bespoke furniture or finishes

How to Keep Your Refurbishment on Track

Strong project management is the best safeguard against delays. A clear scope avoids confusion and scope creep. Involving landlords, IT teams, and contractors early helps streamline approvals. Allowing contingency in both budget and timeframe is wise. Even with good planning, hidden defects or supply chain issues can appear. Weekly updates and regular inspection visits help maintain momentum and keep everyone aligned.

Where relocation isn't possible, phasing works around staff can reduce disruption. It may extend the overall timeframe, but it prevents complete shutdown.

How to Plan Your Office Refurbishment Timeline

  • Define clear objectives (refresh, upgrade, or full renovation)
  • Build a budget that includes design, approvals, and furniture
  • Allow time for approvals and inspections
  • Plan around staff needs (phasing or relocation)
  • Maintain strong project management throughout

Small refurbishments can finish in a few weeks, while major fit-outs may run for six months or more. With planning and approvals added in, the full timeline is usually three to nine months. With clear objectives, realistic budgets, and strong project management, an office refurbishment can be delivered smoothly.
