How Much Does Office Refurbishment Cost in the UK?
Office Refurbishment UK Cost Guide 2026
Office refurbishment costs in the UK can vary significantly depending on the size of the space, the level of work required and the specification of finishes. Whether you are refreshing an existing office or carrying out a full fit-out, understanding realistic costs is essential for planning, budgeting and avoiding unexpected expenses.
Understanding Office Refurbishment Costs in 2026
In 2026, office refurbishment costs in the UK are influenced by several key factors, including rising material prices, labour availability, sustainability requirements and evolving workplace expectations. Businesses are no longer simply updating décor; they are redesigning spaces to support hybrid working, improve productivity and enhance employee wellbeing.
As a result, refurbishment projects can range from relatively simple cosmetic upgrades to complex transformations involving structural changes, mechanical and electrical systems, and high-end finishes. This wide variation makes it essential to understand cost ranges rather than relying on a single average figure.
Most office refurbishment projects in the UK are priced per square metre. This allows businesses to estimate costs based on floor area, but it is only a starting point. The final cost depends on layout complexity, services, materials, access constraints and the condition of the existing building.
Average Office Refurbishment Cost per m² (UK 2026)
| Type of Refurbishment | Typical Cost per m² | Description |
|---|---|---|
| Light Refurbishment | £250 – £500 | Decoration, flooring, minor upgrades, basic improvements |
| Mid-Range Refurbishment | £500 – £1,000 | New layouts, lighting, ceilings, improved finishes |
| High-End Refurbishment | £1,000 – £2,000+ | Bespoke design, premium materials, full upgrades |
| Full Fit-Out (Cat B) | £1,500 – £3,000+ | Complete transformation including services and branding |
These figures are general guidelines based on current UK market trends. Actual costs can vary depending on location, specification and project complexity.
What Affects Office Refurbishment Costs?
Size of the Office
Larger spaces may reduce cost per square metre but increase total project cost significantly.
Design Complexity
Bespoke layouts, meeting rooms and specialist areas increase costs.
Mechanical & Electrical Work
Upgrading lighting, HVAC and electrics can be one of the biggest expenses.
Materials & Finishes
Premium flooring, furniture and finishes increase overall budget.
Building Condition
Older buildings may require additional repair or compliance work.
Location
Costs in cities like London or Manchester are typically higher.
Office Fit-Out Costs: Cat A vs Cat B Explained
When discussing office refurbishment costs in the UK, it is important to understand the difference between Cat A and Cat B fit-outs, as this significantly affects pricing.
Cat A Fit-Out
Basic landlord finish including lighting, ceilings, raised floors and services. Typically costs £500 – £1,500 per m².
Cat B Fit-Out
Fully customised workspace including meeting rooms, branding, furniture and design. Costs £1,500 – £3,000+ per m².
Most businesses require Cat B fit-outs because they create a usable, branded working environment tailored to operations.
Hidden Costs You Should Plan For
- Planning and design fees
- Building regulation compliance
- Furniture and equipment
- IT and cabling infrastructure
- Temporary relocation costs
- Unexpected structural repairs
Many projects exceed budget because these costs are not considered early. A realistic budget should include a contingency of at least 10–15%.
Realistic Cost Examples (UK Office Projects)
To give a clearer idea of how costs work in practice, here are realistic examples based on typical UK office refurbishment projects:
Small Office (50–100 m²)
Light refurbishment with new flooring, decoration and lighting may cost between £15,000 and £40,000 depending on quality and layout changes.
Medium Office (200–500 m²)
A mid-range refurbishment including partitions, meeting rooms and upgraded systems could range from £100,000 to £400,000.
Large Office (1000m²+)
Full fit-out projects with bespoke design, HVAC and branding can exceed £1 million depending on specification.
These examples show why cost per square metre is useful, but real project costs depend heavily on the level of specification and complexity.

Frequently Asked Questions
How much does it cost to refurbish an office in the UK?
Short answer: Office refurbishment costs in the UK typically range from £250 to £2,000+ per square metre depending on the scope, specification and complexity of the project.
In more detail, a basic refurbishment involving decoration, flooring and minor upgrades may fall at the lower end of the scale, while a high-end or full fit-out project can reach significantly higher costs. The biggest variables include mechanical and electrical upgrades, layout changes, furniture, and the overall design specification.

What is included in office refurbishment costs?
Short answer: Office refurbishment costs typically include labour, materials, design, and installation, but may exclude furniture, IT and specialist features.
A standard refurbishment cost usually covers flooring, decoration, ceilings, lighting, partitioning and general construction work. However, additional costs may arise for bespoke furniture, branding elements, advanced lighting systems, air conditioning, and IT infrastructure.
It is important to clarify what is included in any quote. Some contractors provide a turnkey solution, while others may only cover specific elements of the project.
Is it cheaper to refurbish or relocate an office?
Short answer: Refurbishing is often more cost-effective than relocating, but it depends on your business needs.
Relocation involves costs such as lease agreements, moving expenses, downtime and new fit-out requirements. Refurbishment allows businesses to upgrade their existing space without these additional costs.
However, if the current office no longer meets operational needs, relocation may be the better long-term investment.
What is the average office fit-out cost per m² in the UK?
Short answer: Office fit-out costs in the UK typically range from £500 to £3,000+ per square metre depending on whether it is Cat A or Cat B.
A Cat A fit-out provides a basic functional space and is generally more affordable, while a Cat B fit-out includes full customisation such as meeting rooms, branding, furniture and advanced systems, making it significantly more expensive.
Costs can increase further depending on building condition, sustainability requirements, and technology integration.
What is the most expensive part of an office refurbishment?
Short answer: Mechanical and electrical systems are usually the most expensive part of an office refurbishment.
This includes lighting, HVAC systems, data cabling and electrical upgrades. These elements are essential for modern workplaces and can significantly impact overall costs.
Design complexity and high-end finishes can also drive costs higher.
How long does an office refurbishment take in the UK?
Short answer: Most office refurbishments take between 2 to 12 weeks depending on size and complexity.
A small office refresh may take just a few weeks, while larger or more complex projects involving structural changes or full fit-outs can take several months.
Timelines depend on planning, approvals, contractor availability and material lead times.
What factors increase office refurbishment costs the most?
Short answer: Design complexity, M&E systems, and high-end finishes are the biggest cost drivers.
Upgrading electrical systems, installing HVAC, creating bespoke layouts, and using premium materials can significantly increase costs. Location and building condition also play a major role.
Unexpected structural issues can also lead to higher-than-expected costs.
Planning Your Office Refurbishment Budget
Understanding office refurbishment costs is essential for making informed decisions. By considering cost ranges, project scope and potential hidden expenses, businesses can plan effectively and avoid unexpected surprises.
A well-planned refurbishment not only improves your workspace but also enhances productivity, employee satisfaction and long-term business performance.
