“How long will this take?” is one of the first questions any business owner or property manager asks before committing to a refurbishment. It’s also one of the hardest to answer honestly — because the truth is, it depends. A lick of paint and new flooring might take two weeks. A full strip-out and reconfiguration of a multi-floor office could take six months or more.
What follows is a realistic breakdown of how commercial refurbishment timelines actually work, the factors that move the needle in either direction, and how to plan around them.
The Short Answer: It Depends on Scope
As a general guide:
- Small-scale refurbishments (redecoration, new flooring, minor cosmetic updates) — typically 2 to 6 weeks
- Mid-scale fit-outs (new layouts, kitchens, bathrooms, partition walls, lighting) — typically 6 to 12 weeks
- Full refurbishments (strip-out, M&E upgrades, structural alterations, complete reconfiguration) — typically 3 to 6 months, sometimes longer for larger or listed buildings
Hospitality venues such as pubs and restaurants often sit at the faster end of this scale, since most projects focus on front-of-house transformation and kitchen upgrades rather than structural change. Offices, schools, and healthcare facilities tend to take longer, largely due to the complexity of mechanical, electrical and plumbing (MEP) works and stricter compliance requirements.
The Phases That Make Up a Refurbishment Timeline
Understanding where the time actually goes makes the overall timeline far less mysterious.
1. Pre-construction and design (2–8 weeks) Before any work starts on site, there’s a planning phase covering surveys, feasibility, cost planning, and design coordination with architects and engineers. This is also when your contractor should provide accurate cost certainty, so you know exactly what you’re committing to. Rushing this stage is one of the most common causes of delays further down the line.
2. Permissions and approvals (2–6 weeks) Depending on the scope, you may need planning permission, listed building consent, or building regulations approval. Larger structural changes, change-of-use projects, and works to listed buildings typically take longer to clear than straightforward cosmetic refurbishments.
3. Procurement and material lead times (variable) Once designs are finalised, materials need to be ordered. Bespoke joinery, specialist flooring, or made-to-order fixtures can have long lead times, and a good contractor will start this process early to avoid it becoming the bottleneck.
4. Construction (the bulk of the timeline) This is the most visible phase — strip-out, first-fix M&E, structural work, second-fix, finishes, and snagging. For mid-sized commercial fit-outs, this stage typically runs 6 to 12 weeks; for full refurbishments with structural or M&E work, 3 to 6 months is realistic.
5. Snagging and handover (1–2 weeks) Before handover, a thorough walkthrough identifies any remaining issues that need addressing. Building this time into the schedule — rather than treating it as an afterthought — avoids last-minute surprises before you reopen or move in.
What Actually Affects Your Timeline
A few factors consistently make the biggest difference to how long a refurbishment takes:
- Scope and scale — A 3,000 sq ft restaurant fit-out and a 50,000 sq ft office reconfiguration are simply not comparable projects, even if both are called a “refurbishment.”
- Whether the building stays occupied — Refurbishing around live operations (a school during term time, an office with staff still working, a pub trying to stay open) requires careful phasing, and that phasing adds time.
- M&E complexity — Upgrading heating, electrics, ventilation, or plumbing always adds time compared with purely cosmetic work, partly due to specialist trades and partly due to compliance sign-off.
- Building age and condition — Older buildings, listed structures, and properties with hidden issues (asbestos, outdated wiring, structural quirks) often reveal additional work once strip-out begins.
- Decision-making speed — Projects slow down when design sign-offs, material choices, or change requests are delayed on the client side. A clear point of contact and fast turnaround on decisions keeps momentum.
Why the Right Contractor Shortens the Timeline
The single biggest lever for keeping a refurbishment on schedule is having one team manage the whole process — design coordination, procurement, and site delivery — rather than juggling multiple disconnected suppliers. A contractor who assigns a dedicated contracts manager and site supervisor from day one, backed by an in-house quantity surveyor, can identify risks early and keep every trade moving in sequence rather than waiting on each other.
This is particularly true for businesses that can’t afford extended downtime — a pub or restaurant refurbishment during a key trading season, or a school refurbishment that has to work around term dates, simply cannot run over schedule without real financial or operational consequences.
Planning Your Own Project
If you’re weighing up a refurbishment and trying to map out a realistic timeline, it helps to start with two things: a clear scope, and a contractor who can give you honest, accurate timeframes before work begins — not optimistic ones designed to win the job.
