If you own a commercial property in the UK right now, you are sitting on an asset that is being judged more harshly than it was five years ago. Tenants are not just looking for space — they are looking for space that works harder, costs less to run, and meets modern environmental standards. According to Colliers’ 2026 predictions, the market is defined less by capital growth and more by income growth and active asset management. That means the value of your property is no longer about where it sits on a map. It is about what you have done to it. I have watched this shift happen over the last few years, and the pattern is clear: landlords who renovate with purpose are the ones who attract the best tenants and command the highest rents. Those who wait are left with empty units and falling yields.
These figures are not abstract. They reflect a market where prime, well-located, energy-efficient space is in short supply. The Savills cross-sector outlook for 2026 confirms that low development activity combined with normal tenant demand is pushing prime rental growth higher across all sectors. If your property is not in that prime category, you are losing ground. The good news is that renovation can move you into it. Here is what you actually need to know.
What “Prime” Actually Means for Your Commercial Property
The word “prime” gets thrown around a lot, but in the current market it has a very specific meaning. It does not just mean a good postcode. It means a building that meets the environmental, operational, and aesthetic standards that today’s occupiers expect. The Savills report makes this clear: the definition of prime has changed and is more location-specific than ever. A perfect location can compensate for a mediocre building, but only up to a point.
What I tend to notice is that landlords often think of renovation as cosmetic — new paint, new carpets, maybe a fresh sign. That is not what moves the needle anymore. The upgrades that matter are the ones that improve energy performance, reduce running costs, and make the space more flexible. A building with a low EPC rating is becoming unlettable in many markets. If you are planning a renovation, start with the fabric of the building before you touch the finishes. A well-prepared commercial space is one that has been upgraded from the inside out.
Why Renovation Matters More Now Than in the Last Decade
The commercial property market has shifted from a cycle driven by capital growth to one driven by income. That is a fundamental change. In the past, you could buy a building, hold it, and watch its value rise. That is not happening now. The Colliers report states plainly that achieving capital gains through yield compression and passive asset management looks very unlikely given the UK’s relatively high 10-year gilt benchmark. Performance will come from income growth and asset management gains — and that means renovation.
Consider the regional office market. Colliers notes that prime rents across the ‘Big Six’ regional markets are anticipated to increase at 10%, with Birmingham and Bristol already breaching £50 per sq ft, and Manchester expected to follow in 2026. That growth is not happening across the board. It is happening in buildings that meet the new standard. If your property is in one of those cities but has not been upgraded, you are watching that rental growth pass you by.
Here is a scenario: you own a 5,000 sq ft office in Manchester that rents at £40 per sq ft. A renovated competitor down the road is achieving £50 per sq ft. That is an extra £50,000 per year in rent. The cost of a meaningful renovation — new HVAC, improved insulation, upgraded lighting, better common areas — might be £100,000 to £150,000. The payback period is two to three years. After that, the additional income is pure upside. My first move would be to get an EPC assessment and a condition survey before doing anything else. That tells you where the biggest gains are.
Where Landlords Get Renovation Wrong
I see the same mistakes repeated. They cost landlords time, money, and tenants. Here are the most common ones, backed by what the research tells us.
Focusing on Cosmetic Changes Instead of Performance Upgrades
New flooring and a coat of paint might make a space look better, but they do not make it perform better. Tenants care about energy costs, comfort, and sustainability. The Savills report highlights that occupiers prioritise ESG-aligned, energy-efficient, best-in-class space. If your renovation does not improve the EPC rating or reduce running costs, you have spent money that will not come back in higher rent. A commercial rent negotiation is much harder when the building itself is the weak point.
Ignoring the Supply Dynamics in Your Micro-Market
Headline vacancy rates can be misleading. Savills points out that in both retail and logistics, a high headline vacancy rate can hide substantially lower availability in prime or dominant schemes. The same applies to offices. You need to understand the supply picture at the micro-market level, not the city level. If there is a shortage of prime space in your specific area, renovation can capture that premium. If there is an oversupply of similar unrenovated space, you need to differentiate more aggressively.
Underestimating the Cost and Complexity of Compliance Upgrades
Minimum Energy Efficiency Standards (MEES) are tightening. From 2027, it will be unlawful to let a commercial property with an EPC rating below C. That deadline is closer than it feels. Many landlords put off the work and then face a scramble when a tenant leaves and the building cannot be re-let. The cost of a last-minute upgrade is always higher than a planned one. If you are unsure where you stand, speaking with a property lawyer who understands compliance timelines can save you from a costly mistake.
Renovating Without a Clear Tenant Profile in Mind
Different tenants want different things. A law firm wants private offices and meeting rooms. A tech company wants open-plan space with breakout areas. A logistics operator wants high eaves and good loading. If you renovate for a generic tenant, you end up with a generic space that competes on price. The Colliers report notes that occupiers are highly selective on location and building quality. Know who you are targeting before you spend a pound.

A successful renovation is not about spending the most money. It is about spending money in the right places. Here is a practical guide based on what the research tells us works.
Start With an Energy Performance Audit
Your EPC rating is the single most important metric for lettability. If it is below C, you cannot let the property from 2027. Even if it is a C or above, improving it to a B or A gives you a competitive advantage. An energy audit will identify the biggest gains: insulation, glazing, heating systems, lighting. Prioritise these over everything else. A step-by-step approach to preparing your space should always begin with the building’s performance.
-
1Commission an EPC AssessmentHire an accredited assessor to produce a current EPC and a recommendations report. This tells you exactly which upgrades will improve the rating and by how much.
-
2Prioritise Fabric UpgradesInsulation, glazing, and air sealing deliver the biggest energy savings. These upgrades also improve comfort, which tenants notice immediately.
-
3Upgrade Heating and LightingReplace old boilers with heat pumps or high-efficiency systems. Switch to LED lighting with motion sensors. These changes reduce running costs and improve EPC scores.
-
4Reassess and CertifyOnce work is complete, get a new EPC certificate. Use the improved rating as a marketing tool when listing the property.
Target the Right Tenant With the Right Layout
The days of the generic office floorplate are ending. Tenants want flexible, adaptable space that can grow or shrink with their needs. Consider installing demountable partitions, raised floors with accessible cabling, and modular furniture systems. If you are targeting the growing regional office market, think about what occupiers in Birmingham, Bristol, or Manchester actually need. The Colliers report notes that occupiers are prioritising “plug & play” provisions — fitted, ready-to-use space that reduces their fit-out costs. That is a direct opportunity for you.
Don’t Forget Security and Safety Infrastructure
Modern tenants expect a building that is secure and safe. This is not just about locks and alarms. It is about integrated systems that give tenants peace of mind and reduce their insurance costs. A monitored alarm system, smart locks, and water leak detectors are relatively inexpensive additions that signal a well-managed building. A home security starter kit designed for commercial use can cover multiple entry points and provide remote monitoring. For larger properties, consider a full access control system. These upgrades also protect your asset from damage and liability.
Plan for the Emerging Data Centre and AI Demand
This is an underreported angle that deserves its own subsection. The Savills report identifies the AI and cloud-driven boom in demand for data centre space as the standout trend of 2025, and it is not going away. While most commercial landlords are not building data centres, the competition for land and power-enabled sites is affecting the wider market. Logistics developers are being outbid for key sites. If your property has good power infrastructure, high ceilings, and strong connectivity, it may be attractive to data centre operators or tech tenants who need server space. Renovating with high-capacity power and fibre connectivity in mind could open up a completely different tenant pool.

Your Next Move
The commercial property market in 2026 rewards action. The landlords who will benefit from rising prime rents and strong tenant demand are the ones who invest in their buildings now. You do not need to do everything at once. Start with an EPC assessment and a condition survey. Identify the upgrades that will move your property into the prime category. Then execute them in order of impact. The gap between renovated and unrenovated space is widening, and it will not close on its own.
