Planning commercial property upgrades requires a strong understanding of financial commitments, as costs can escalate quickly if the scope, specification or building condition is not fully assessed at the outset. Without a defined budget, projects are more likely to encounter delays, design changes or reductions in quality as a result of efforts to manage overspending. A well-established financial framework also allows decision-makers to prioritise elements such as layout, materials and infrastructure, to align the operational needs and long-term business objectives of a project.
In this guide to office refurbishment costs, we break down the figures, highlight industry trends and explain the variables that dictate your overall budget. By understanding the process, you can make informed decisions about your project.
The term “refurbishment” covers a wide range of work, and defining the scope is the first step in setting an accurate budget. At a basic level, office refurbishment can involve cosmetic improvements such as updating finishes, repainting or replacing furniture. These changes tend to have a lower cost and shorter programme.
More extensive refurbishments involve structural alterations and upgrades to core systems. This can include moving or removing walls, reconfiguring layouts or upgrading plumbing and mechanical services. Work of this nature requires greater investment and more detailed planning, as it affects how the building operates as a whole.
Refurbishment projects are often considered alongside Cat A and Cat B standards, which help define the condition and level of completion within a commercial space:
An office fit-out refers to the process of preparing an internal space so it can be occupied and used for its intended purpose. In commercial buildings, this typically involves installing the functional and aesthetic elements a business needs to operate, including partitioning, flooring, lighting, mechanical and electrical systems, furniture, and IT infrastructure. The level of work can vary depending on the starting condition of the space, ranging from a basic setup to a fully customised environment aligned with a company’s brand and operational requirements.
A fit-out usually takes place within a new or recently handed-over space, where the structure of the building is already complete but the interior has not yet been adapted for use. The focus is on turning an empty or generic interior into a practical working environment.
A refurbishment, by contrast, involves improving or updating an existing space that is already in use or has been previously fitted out. This may include replacing finishes, upgrading building services, reconfiguring layouts or bringing the space in line with current standards. While a fit-out starts from a relatively blank canvas, a refurbishment works with what is already in place, often requiring removal, alteration or upgrading of existing elements.
In practice, the two can overlap. A project may involve refurbishing parts of a space while fitting out others. The distinction lies in the starting point - fit-outs create a usable environment from an unfinished interior, while refurbishments improve or adapt an existing one.
How much does an office fit-out cost in 2026? Pricing is largely dictated by your chosen quality and scope, alongside factors such as building condition, required services and location.
These figures provide a general guide, but every project differs based on site conditions and business requirements. For a more accurate assessment of your likely costs, get in touch with Contact One to discuss your project in detail.
Understanding how your budget is divided helps prevent overspending. We recommend breaking the budget into distinct categories to maintain strict financial control.
Professional fees: covers architects, engineers and project managers. Expert project management ensures the project stays on track and helps avoid costly errors or unsatisfactory results.
The physical state of your new space heavily dictates the final price. Older buildings often hide legacy issues. You may uncover outdated electrical systems or plumbing that require complete replacement to meet compliance standards.
Site visits and early engagement with contractors help identify these hidden structural or compliance issues before work begins. Moving into a new office space requires rigorous building evaluation. Assessing building conditions early mitigates risk and protects your budget from unexpected shocks.
Even with detailed planning, unexpected issues arise. We always advise clients to build a safety net into their financial planning, typically allocating an approximate 10–20% for contingencies. This covers unforeseen elements that emerge once walls are opened.
Hidden expenses can include required fire strategy upgrades, asbestos removal, unexpected network cabling changes or building permits. Furthermore, refurbishing an occupied environment is typically more expensive due to phased work requirements. Working "in-situ" means contractors must operate out of hours to minimise disruption, attracting premium labour rates. Taking early action on these factors ensures a more predictable cost.
Eco-conscious design is now standard, with many businesses opting for sustainable materials despite higher initial investments.
Incorporating sustainable materials - such as PET acoustic panels, reclaimed wood and low-VOC paints - significantly reduces lifecycle costs and aligns with corporate ESG guidelines. Choosing energy-efficient systems often leads to long-term savings and an enhanced company reputation. We also recommend reusing existing assets; repurposing or re-upholstering furniture reduces waste and lowers expenditure.
While green certifications like LEED or BREEAM incur additional documentation costs, the resulting reduced utility bills and asset appreciation typically deliver a return on investment within three to seven years.
A worked example helps illustrate how these costs come together in practice. If a business takes on 10,000 sq ft of office space in a major regional city and targets a mid-range specification at £85 per sq ft, this creates a baseline project budget of £850,000.
A typical cost allocation may look as follows:
In addition to these core costs, a contingency of around 15% (£127,500) is typically held to account for unforeseen issues, such as site constraints or design changes. This brings the total projected investment to approximately £977,500.
This type of breakdown shows how quickly costs accumulate across different areas and why each element needs to be monitored throughout the project.
A clear, staged process helps account for costs early and reduces the risk of overspend or delays. Breaking the project into defined steps allows for better control over both design and delivery. Working with an experienced partner such as Contact One means each stage is managed cohesively, from initial assessment through to final delivery, with budgeting and project management handled as a single, coordinated process.
Contact One oversees the full budgeting process, managing procurement, timelines and delivery to keep the project aligned with the agreed financial framework.
Delivering a commercial refurbishment requires careful planning, accurate cost control, and consistent oversight from start to finish. At Contact One, we recognise that each project represents a substantial financial commitment, with decisions that affect both day-to-day operations and long-term business performance.
We work closely with our clients to deliver spaces that reflect how their business operates, while maintaining control over costs and timelines. Our approach includes:
A well-planned refurbishment improves how a space functions, how teams work and how a business presents itself. With the right level of oversight and planning, the process remains controlled and predictable.
