If you own a commercial property in the UK, you’ve probably asked yourself whether investing in refurbishment is actually worth it. Perhaps your building is looking a bit tired, tenants are asking for improvements, or you’re considering selling and want to maximize your return.
The short answer is yes. Commercial property refurbishment typically increases value by 10 to 25 percent, depending on the type of property, its location, and the scope of works undertaken. But the real question isn’t whether refurbishment adds value, it’s understanding how much value you can realistically expect and which improvements deliver the strongest returns.
In this guide, we’ll walk you through everything you need to know about increasing your commercial property’s value through strategic refurbishment. We’ll cover specific figures, break down costs versus returns, and share insights from real UK projects.

The Short Answer: Yes, Here’s How Much Value You Can Expect
Commercial property refurbishment consistently delivers measurable value increases across the UK market. Recent data from Savills shows that the rental gap between newly built offices and well-refurbished spaces has narrowed dramatically. Across the Big Six regional office markets, that gap now stands at just £1.50 per square foot half what it was in 2019.
What does this mean for property owners? It means that tenants increasingly see quality refurbished space as comparable to new builds, and they’re willing to pay accordingly.
The value increase you can expect depends largely on your starting point and ambition level. A light cosmetic refresh typically adds 5 to 10 percent to property value. Moderate refurbishment involving mechanical and electrical upgrades alongside interior improvements can boost value by 10 to 18 percent. Comprehensive refurbishment that addresses the building fabric, all services, and creates genuinely modern space regularly achieves 15 to 25 percent or more.
One compelling example is Aurora in Glasgow. This 174,000 square foot office underwent comprehensive refurbishment and has since let 167,000 square feet across seven separate deals. Rents reached £41.50 per square foot, representing an 11 percent increase from the first letting. That’s concrete evidence of what strategic refurbishment achieves in today’s market.
Value Increase by Commercial Property Type
Not all commercial properties respond to refurbishment in the same way. Understanding how different asset classes perform helps you set realistic expectations and prioritise your investment.
Office Buildings
The office market has transformed since 2020. Businesses now scrutinise workplace quality more carefully than ever, seeking spaces that attract employees back to the office and support hybrid working patterns. This flight to quality means Grade A refurbished offices command significant premiums over dated Grade B and C stock.
Currently, 84 percent of office space expected to be delivered across the UK’s Big Six regional markets over the next three years will come from refurbished stock rather than new builds. That statistic alone tells you where the market is heading.
Key value drivers for office refurbishment include improved air quality and ventilation, flexible layouts that support collaboration and focused work, enhanced common areas and amenities, and strong sustainability credentials. Tenants want buildings that help them attract talent, and they’ll pay premium rents to get them.
Retail Units
The retail sector has faced significant challenges, but strategic refurbishment can reposition struggling assets for success. Modern retail refurbishment focuses on creating experiential spaces, accommodating click-and-collect operations, and ensuring the property suits contemporary retail formats.
High street units that undergo thoughtful modernisation often achieve rental uplifts of 8 to 15 percent, particularly when improvements enhance the customer experience and support omnichannel retail operations.
Industrial and Warehouse Properties
Industrial property remains one of the strongest performing commercial sectors in the UK. Refurbishment opportunities here focus on practical improvements that matter to logistics operators. Increasing eaves height where structurally possible, upgrading loading facilities, improving energy performance, and adding temperature-controlled areas all drive value.
Given the shortage of quality industrial stock in many locations, even modest refurbishment can significantly improve lettability and rental levels.
Mixed-Use Developments
Properties combining retail, office, and residential elements benefit from refurbishment that creates coherent, attractive environments. Improved common areas, better integration between uses, and enhanced external presentation all contribute to value across the entire asset.
Which Refurbishment Improvements Deliver the Highest ROI?
When budgets are finite, focusing investment on improvements that deliver the strongest returns makes sense. Here’s where your money works hardest.
EPC and Energy Efficiency Upgrades
Energy performance has become a critical value driver for commercial property. Current Minimum Energy Efficiency Standards already prohibit letting properties rated below E. Proposed regulations will tighten this to C and eventually B over coming years.
Properties with poor energy ratings face a stark choice: refurbish to comply or become unlettable. But beyond mere compliance, strong energy performance now commands rental premiums. Tenants face their own sustainability targets and actively seek buildings that support their ESG goals.
Practical improvements include upgrading to LED lighting with smart controls, which typically reduces lighting energy consumption by over 50 percent. Modern HVAC systems dramatically cut energy use while improving occupant comfort. Enhanced insulation and high-performance glazing reduce heating and cooling demands.
At Buon Construction, we regularly help clients navigate energy improvement projects, ensuring works deliver both compliance and genuine value enhancement.
Mechanical and Electrical Systems
Outdated M&E systems create risk for occupiers and suppress property values. Modern businesses depend on reliable power, data connectivity, and climate control. Buildings that can’t deliver these fundamentals simply don’t compete.
Upgrading mechanical and electrical infrastructure signals to tenants and valuers alike that the property is fit for modern business. Smart building controls that optimise energy use while maintaining comfort increasingly feature in premium lettings.
Interior and Common Area Improvements
First impressions matter enormously. Reception areas, common spaces, and the general feel of a building influence both tenant decisions and the rents achievable.
Research by Human Spaces found that employees in workplaces featuring natural elements reported 15 percent higher wellbeing, were 6 percent more productive, and 15 percent more creative. Biophilic design principles incorporating plants, natural materials, and daylight increasingly feature in successful refurbishment projects.
Amenity provision has also become a key differentiator. Secure cycle storage, shower facilities, breakout spaces, and even on-site fitness areas help landlords compete for quality tenants in competitive markets.
External and Curb Appeal
Never underestimate the impact of external presentation. A tired façade, poor signage, or neglected landscaping creates negative impressions before anyone steps inside. External improvements often deliver disproportionate value relative to their cost.
Fresh external decoration, improved entrance areas, updated signage, and well-maintained landscaping all contribute to lettability and rental potential.
Commercial Refurbishment Costs vs Value Increase
Understanding the relationship between investment and return helps you make informed decisions. UK commercial refurbishment costs vary considerably based on scope and specification.
Light refurbishment focusing on cosmetic improvements typically costs £20 to £50 per square foot. This might include redecoration, new flooring, basic lighting upgrades, and minor repairs. Value increases of 5 to 10 percent are realistic for this level of work.
Medium refurbishment involving M&E upgrades, layout reconfiguration, and more substantial interior works generally runs £50 to £100 per square foot. Expect value increases of 10 to 18 percent.
Comprehensive refurbishment addressing building fabric, complete M&E replacement, and creating genuinely Grade A space typically costs £100 to £180 or more per square foot. However, this level of investment regularly delivers value increases of 15 to 25 percent and transforms previously unlettable buildings into premium assets.
The key is matching investment to opportunity. A well-located building with good fundamentals but tired presentation might need only modest investment to unlock significant value. Conversely, a building requiring comprehensive works needs careful analysis to ensure the numbers stack up.
Buon Construction works closely with clients during the feasibility stage, helping assess whether proposed refurbishment represents sound investment for each specific property.
When Commercial Refurbishment Isn’t Worth It
Honest advice sometimes means recommending refurbishment. Certain circumstances simply don’t support the investment.
Location fundamentally determines property value. A building in a declining area or poor micro-location won’t suddenly become desirable because of refurbishment. No amount of investment overcomes the wrong location.
Some buildings have fundamental limitations that refurbishment cannot address. Floor-to-ceiling heights below 2.7 metres severely restrict office appeal. Structural configurations that prevent efficient layouts limit value potential. These inherent constraints may mean alternative strategies change of use or redevelopment make more sense than refurbishment.
Market conditions matter too. Refurbishing into an oversupplied market risks investing capital that cannot be recovered through rents or sale price. Understanding local supply and demand dynamics is essential before committing to major works.
Finally, consider your holding period. Refurbishment investment needs adequate time to deliver returns through improved rents or enhanced sale price. If you’re planning to sell within twelve months, comprehensive refurbishment may not be the right approach.
How to Finance Your Commercial Property Refurbishment
Funding refurbishment requires careful consideration of available options and their implications.
Bridging and Development Finance
Short-term bridging finance suits refurbishment projects well. Loans typically run from six to twenty-four months, providing capital for works with the expectation of refinancing or sale on completion. Rates vary based on loan-to-value, property type, and lender appetite, but expect to pay between 0.5 and 1.5 percent monthly.
Commercial Mortgages with Works Provision
Some commercial mortgage products include provision for refurbishment works within the facility. This can simplify funding while potentially offering better rates than standalone bridging. Speak with specialist commercial mortgage brokers about available options.
Capital Allowances and Tax Incentives
Many refurbishment elements qualify for capital allowances, effectively reducing the net cost of works. Integral features including electrical systems, heating, and ventilation can attract allowances. Specialist tax advice helps maximise these benefits.
Green Finance
Sustainability-linked finance products increasingly offer preferential terms for projects delivering genuine environmental improvements. BREEAM-certified refurbishments and those achieving significant EPC improvements may access better rates.
UK Regulatory Requirements That Impact Value
Regulatory compliance has become inseparable from commercial property value. Understanding current and upcoming requirements helps you plan effectively.
The Minimum Energy Efficiency Standards already prevent letting properties rated below E. Current proposals would tighten this to C and eventually B, though exact timelines remain subject to consultation. What’s certain is the direction of travel energy performance requirements will only increase.
BREEAM certification provides third-party verification of building sustainability. While not legally required, certification at Very Good or Excellent levels increasingly features in tenant requirements, particularly for larger corporate occupiers with ESG reporting obligations.
Building safety regulations continue evolving, with enhanced requirements for fire safety, accessibility, and general compliance. Refurbishment provides an opportunity to address these requirements proactively.
The Commercial Refurbishment Process
Understanding what’s involved helps you plan realistic timelines and budgets.
The journey typically begins with assessment and feasibility work. This establishes the building’s current condition, identifies constraints and opportunities, and develops initial cost estimates. Allow two to four weeks for this stage.
Design development follows, with architects and engineers developing proposals that meet your objectives within budget. Planning applications may be needed depending on the scope. This stage typically takes four to eight weeks.
Contractor procurement involves obtaining competitive tenders and selecting appropriate delivery partners. Buon Construction can provide early guidance during this stage, helping clients understand likely costs and timelines.
Construction duration varies enormously based on scope. Light refurbishment might complete in four to eight weeks. Moderate works typically take eight to sixteen weeks. Comprehensive refurbishment often requires sixteen to thirty weeks or more.
