How Much Does a Modular Office Cost in the UK?
A Practical Guide to Prices, Options, and Smart Alternatives for 2025
If you’ve been looking for more workspace — whether that’s a home office, business hub, or site cabin — you’ve probably realised the market is full of mixed messages.
Some quotes sound too good to be true. Others spiral once “extras” are added.
So, let’s make it simple.
Here’s what modular offices really cost in the UK — and how to make sure you’re comparing like for like.
1️⃣ The Straight Answer — Real UK Prices
At CCP Modular, we supply both new and refurbished modular offices to suit different budgets.
Here’s a clear breakdown:
| Type | Size | Price (ex. VAT) | Notes |
|---|---|---|---|
| Refurbished Office Cabin | 20ft x 8ft | From £6,500 | Fully insulated, ready to use, great value for smaller setups |
| New Modular Office | 20ft x 8ft | From £8,500 | Modern, insulated, fully compliant workspace |
| Premium “Containex Plus Line” Office | 20ft x 8ft | From £15,000 | European-built, long lifespan, high-spec finish and sound insulation |
| Bespoke Multi-Unit Office Block | Custom | From £20,000+ | Linked units, kitchens, toilets, meeting rooms — tailored design |
Add-ons like cladding, heating/cooling, lighting upgrades, and furniture are optional and can be matched to your budget.
The goal is flexibility — you start with a solid, insulated structure and build up from there.
2️⃣ Modular vs Traditional — What Are You Really Paying For?
Let’s put modular in context.
| Option | Average Cost per m² | Timeline | Key Features |
|---|---|---|---|
| Traditional Brick Extension | £1,500–£2,000 | 6–12 months | Permanent but slow, messy, expensive |
| Garden Office Pod | £1,200–£1,600 | 8–10 weeks | Compact, stylish, limited scalability |
| Modular Office Cabin | £800–£1,000 | 3–6 weeks | Fast install, flexible layout, portable |
| Refurbished Modular Unit | £500–£800 | 1–2 weeks | Affordable, practical, ready-to-go workspace |
That’s why modular wins — you get speed, certainty, and professional space at around half the cost of a traditional extension.
Plus, it’s classed as a movable asset, not a fixed building, which often means fewer planning hurdles and tax advantages for businesses.
3️⃣ What Drives the Price Up (and How to Stay Smart)
Every project is unique, but here’s what really moves the needle on price:
-
Size & configuration: Single unit or linked block?
-
Insulation & energy spec: Higher insulation = lower running costs.
-
Exterior finish: Standard steel vs timber or composite cladding.
-
Internal fit-out: Simple office vs full meeting suite.
-
Groundworks & delivery: Access and crane lift requirements.
💡 Pro tip: plan your layout early and share site photos — it helps us give you the most accurate cost upfront (and stops surprise charges later).
4️⃣ Why More Professionals Are Choosing Modular
Here’s what our clients tell us they love most:
✅ Speed – installed in days, not months.
✅ Flexibility – add more space later if the business grows.
✅ Comfort – warm, bright, and quiet, with optional air-con and premium finishes.
✅ Value retention – can be moved, resold, or repurposed.

Whether it’s a home-based consultant, construction firm, or creative agency, modular offices have become the go-to choice for professionals who want a proper workspace without the permanent price tag.
