Owner occupiers – the SME advantage
By Marc Callaghan,
Head of Specialist Finance at OSB Group
In today’s ever-changing commercial property market, more SMEs are looking beyond leasing and are diversifying into ownership. We explore what’s driving this trend, what challenges remain, and how specialist commercial lenders like InterBay can help investors create opportunities for future growth.

The owner occupier sector is going from strength to strength.
According to latest data from CoStar1, in Q1 2025, the total volume of commercial property acquired for owner occupation in the UK was £2.8bn, a significant portion of the overall £8.9bn invested in UK commercial real estate.
On 23 June 23, 2025, the UK Government published its 10-year Modern Industrial Strategy aiming to boost business investment and growth in key high-growth potential areas such as advanced manufacturing, digital and technology.
If this is to be successful, then SMEs within owner occupied industrial/warehouses and offices may need to be the driving force behind it. June 2025 also heralded the Government’s 10-Year UK Infrastructure Strategy. With £1.35bn of public funding now available, businesses are gaining confidence; industrial occupational demand improved by 10% during Q2 2025, and it’s hoped that this trend will continue.
Market improvements
Office investment also gained momentum in 2025. The sector accounted for the highest share of UK transaction volumes in H1, at 21%, according to CBRE. Industry data from CoStar suggests that UK office take-up has risen to a three-year high and the UK office vacancy rate has stabilised1, helped by a 10-year low in office construction.
In particular, the UK “Big Nine” regional office cities outside of London (Birmingham, Bristol, Cardiff, Edinburgh, Glasgow, Leeds, Liverpool, Manchester and Newcastle) has seen collective take-up reach 3.7m sq ft2, 6% ahead of the 10-year average. Driven by a lack of Grade-A space in city centres, occupiers are increasingly looking out of town. Six of the 10 largest deals in H1 2025 were outside the city centre, compared with 2024 where all top 10 deals took place in city centre locations4.
With a limited construction pipeline, this could place upward pressure on rents, enhancing returns and unlocking further investment activity3. Improving retail sales could also be aiding retailer performance with average weekly volumes 2.3% higher during Q2 2025 compared with last year4.

Challenges remain
The owner occupier market continues to face several challenges, including economic uncertainties such as inflation and rising interest rates, which impact affordability and borrowing costs.
Additionally, a shortage of available properties, in the face of high demand, makes it difficult for potential buyers to find suitable properties. Navigating changing occupier needs, such as hybrid working patterns and the need for sustainable spaces, adds another layer of complexity.
InterBay’s impact
We're well-placed to help brokers and their clients navigate such intricacies. We support a variety of asset classes, from florists to children’s nurseries, distribution warehouses and small retail units. When it comes to SMEs, we know the market, have clear criteria and our team of experts work closely with brokers to help borrowers secure the funding they need.
For instance, when reviewing cases, we:
- use the last two years’ finalised accounts so we see three years’ worth of figures;
- look at the performance of the business the experience of the owners, and the specifics of the property; and
- aim to meet with the borrowers directly for loans over £4m, so that we can fully understand their background and plans.

We also may look at securing on another property to help get the borrowing level required or mitigate risk in other ways. This includes requesting capital and interest payments to help bring the risk down over the term or including other assets of the business in debentures. When reviewing accounts, we look at EBITDA (earnings before interest, taxes, depreciation, and amortization) where necessary. This means that on occasion, despite a company reporting a loss, our affordability requirements may still be met.
In addition, we take exceptional items into consideration, such as legal costs, repairs, research and development. Every business and property is different so we look at each loan on its merits and balance out risks (where possible) to solve clients’ complex cases.
