The UK property market is shifting, and savvy investors are looking for the best way to maximise returns while navigating rising costs and regulatory changes. One strategy that stands out in 2025 is converting underutilised commercial properties into Houses of Multiple Occupation (HMOs).
With rising interest rates, tax changes, and increased demand for affordable, high-quality rental accommodation, commercial-to-HMO conversions present a golden opportunity for investors willing to think outside the box. If you’ve been on the fence about this strategy, here’s why now is the best time to act.
The Perfect Storm for Commercial-to-HMO Conversions
The advantages of converting commercial buildings to HMOs come down to three key factors, what we call the 3 P’s: Price, Profit, and Possibility. But before we dive into them, let’s look at why 2025 is particularly ripe for this strategy.
Lower Commercial Property Prices: With the continued fallout from changing work patterns and high street closures, many landlords and businesses are offloading commercial properties at discounted prices. This presents a chance to acquire valuable square footage for significantly less than comparable residential properties.
Government Incentives & Planning Opportunities: The UK government has been making moves to encourage commercial property repurposing through permitted development (PD) rights. This can simplify and speed up the planning process, reducing red tape for investors looking to convert redundant spaces into much-needed housing.
Higher Demand for Affordable Rental Homes: The cost-of-living crisis has driven more people towards shared accommodation as a way to access better-quality housing at a lower cost. High-end, well-designed HMOs are in demand, particularly among young professionals, key workers, and students.
Tax and Financing Advantages: With recent increases in Stamp Duty on additional residential properties, commercial properties offer a tax-efficient alternative. Additionally, VAT on conversion projects can likely be reduced from 20% to just 5% for qualifying conversions.
Now, let’s break down the 3 P’s that make this investment strategy so powerful.
1. Price – Buying at a Discount
Commercial properties tend to be significantly cheaper per square metre than residential properties, with residential space averaging 50% more expensive.This means that as an investor, you can secure a sizeable discount on the space you buy, which in turn increases your potential rental income.
Other financial advantages include:
Lower Stamp Duty: Unlike residential property purchases, commercial and uninhabitable properties qualify for reduced Stamp Duty Land Tax (SDLT) rates.
VAT Benefits: When converting commercial spaces into residential use, the VAT rate drops to 5% instead of 20%, saving thousands.
The result? You can buy bigger, pay less, and optimise your budget for conversion work that adds real value.
2. Profit – Maximising Returns with HMOs
HMOs offer one of the highest-yielding property strategies due to their multiple income streams from multiple tenants. By increasing the number of rentable rooms, you scale your cash flow and boost overall profits.
Key financial advantages:
Higher Rental Yields: Compared to single lets, HMOs generate significantly more income per square foot.
Commercial Valuations: Unlike standard homes, converted HMOs are often valued based on rental income rather than the sale prices of comparable properties in the local area. This can result in a significantly higher final valuation.
Recycling Your Cash: With the potential for higher valuations, you can extract your original capital and reinvest it into new projects, creating a sustainable growth model.
3. Possibility – Creativity, Flexibility, and Sustainability
Commercial buildings often provide more layout flexibility than standard residential properties. This means you can get creative in your designs, incorporating premium features such as:
Larger communal areas (e.g., co-working spaces, cinema rooms, gym facilities)
High-end kitchen and bathroom facilities
Energy-efficient solutions such as solar panels, underfloor heating, and air-source heat pumps
Additionally, converting underused commercial spaces into residential accommodation aligns with government objectives to increase housing stock and revitalise urban areas.
Case Study 1: A Large-Scale HMO in an Article 4 Area
The Property: A former care provider’s office in Portsmouth
Purchase Price: £375,000
Refurbishment Costs: £700,000
Location: Article 4 area (where new HMOs require planning permission)
Proposed Conversion: 13-bed en-suite HMO
Estimated GDV: £1,500,000
Estimated Cashflow: c. £4,000pcm
Challenges & Outcome:
The project took two years to obtain planning approval, partially due to delays caused by the pandemic.
The planning committee was initially hesitant due to the scale of the project, but after reviewing the design, they supported it.
The final design includes three communal kitchen spaces designed for different purposes:
Large kitchen/diner
Cinema room/lounge-style kitchen
Co-working-focused kitchen on the top floor
Despite the challenges, the final development represents a significant uplift in value, offering strong rental demand and high cash flow potential.
Case Study 2: Office to HMO Cluster Flats
In 2018, I acquired an office building at 250 Wellington Road South for £370,000. The property had permitted development rights for up to nine flats. Collaborating with planning experts and architects, we reimagined the space to cater to the co-living market, resulting in seven high-spec flats comprising a total of 20 bedrooms. The design aimed to maximise space while preserving the building's original character, appealing to Manchester's professional community seeking upscale co-living options.
The development process spanned over 18 months, during which significant structural upgrades and reconfigurations were undertaken:
Basement Transformation: Partial tanking and the addition of new light wells made the basement habitable.
Upper Floors and Loft Conversion: The ground and first floors underwent comprehensive refurbishment. The loft area was reconfigured with new skylights to create an additional apartment.
External and Heritage Enhancements: Located near a conservation area, the project included installing conservation-style sash windows and maintaining structural integrity to respect the area's heritage while offering a modern living experience. An interior designer ensured each unit featured a high-end aesthetic tailored for young professionals, blending functionality with style.
Conversion Highlights
Key aspects of the conversion included:
Full damp-proofing and ground-floor DPC installation.
Structural enhancements with RSJs to allow for redesigned internal layouts.
Installation of new internal walls and a three-phase mains electric system.
Soundproofed, conservation-style windows complementing the building’s heritage.
En-suite facilities for all 20 bedrooms and the creation of seven kitchen/dining/living spaces adhering to HMO standards.
Results and Investment ReturnsThe project concluded with impressive financial outcomes:
Purchase: £370,000
Works: £525,000
Monthly Rental Income: £13,965
Monthly Cashflow: c. £4,000
Sold Price: £1.465 million
Case Study 3: Manchester Suburb Co-Living Space
The Property: A vacant hotel with a bar in central Wigan
Original Use: Hotel
Purchase Price: £350,000
Proposed Conversion: 15-bed co-living HMO + café + office
Refurb Costs: TBC
Estimated GDV: £1,250,000–£1,350,000
Estimated Cashflow: £3,500
Project Highlights
Planning permission looks likely to be granted early this year.
Wigan has a lot of anti-HMO rhetoric in the local press, so we ensured we got ahead of the curve by lobbying local councillors about the scheme. They were impressed in principle and, after we put on a local public event, were sold on our scheme as a good way to repurpose the building.
Positioned in a prime location with strong tenant demand, ensuring long-term rental stability.
This is a meticulously designed co-living development aimed at providing high-quality accommodation for young professionals. The property features 15 premium en-suite double bedrooms, each averaging 13.21 square metres (excluding en-suite facilities), surpassing the minimum size requirements for single occupancy rooms.
These "living bedrooms" are equipped with essential amenities, including beds, wardrobes, bedside tables, and desks, ensuring ample storage, privacy, and comfort.
The communal areas are expansive, totalling over 73 square metres across four rooms, with three of these spaces featuring cooking facilities. This design provides 2.65 times the space required under local council standards, fostering a sense of community while prioritising residents' mental well-being.
It also includes a robust management plan, built on extensive experience, supporting efficient waste management with both incentives and financial structures in place. This approach ensures the maintenance of communal harmony and the overall quality of living within the property.
This project exemplifies a commitment to creating premium, harmonious living environments that cater to the needs of modern young professionals. Its thoughtful design and management make it a standout example of successful co-living accommodation.
