Cambridge has long been one of England’s most resilient lettings markets. A world-class university, a thriving tech and biomedical cluster, and a chronic shortage of affordable housing all combine to keep rental demand consistently high. But for landlords running – or considering – houses in multiple occupations, the regulatory landscape in 2026 is more demanding than ever.
From Cambridge City Council’s additional licensing scheme to Article 4 restrictions and the incoming changes under the Renters’ Rights Act, getting your HMO strategy right has never been more important. This guide from Belvoir Cambridge breaks down exactly what you need to know, area by area.
What counts as an HMO in Cambridge?
An HMO, or house in multiple occupation, is a property rented by three or more people who form more than one household and share facilities such as a kitchen or bathroom.
In England, a mandatory licence is required for any HMO occupied by five or more people forming two or more households. Cambridge City Council goes further, however, and operates an additional HMO licensing scheme covering smaller HMOs of three or four occupants across much of the city.
If you own any HMO in Cambridge – regardless of size – you should assume a licence is required and verify directly with the council before letting it.
Cambridge City Council’s additional licensing scheme
Cambridge City Council’s additional licensing designation covers a significant portion of the city, targeting areas of high HMO concentration where management standards have historically been inconsistent.
Licences require landlords to demonstrate that the property meets prescribed space standards, that fire safety measures are in place, and that management arrangements are satisfactory. Licence fees apply per property, and failure to hold a valid licence can result in a civil penalty of up to £30,000, a rent repayment order, and inclusion on the national database of rogue landlords.
The council has stepped up enforcement activity in recent years, with inspections and penalty notices becoming more common. Landlords with portfolios of HMOs across Cambridge should carry out a full compliance audit if they have not done so recently.
Article 4 directions and planning restrictions
Cambridge operates Article 4 directions in several areas, removing permitted development rights that would otherwise allow a property to convert from a standard dwelling (Use Class C3) to a small HMO (Use Class C4) without planning permission.
This means that in Article 4 areas, you will need to apply for planning consent before converting a property into an HMO. Applications are assessed against local planning policy, and approval is not guaranteed.
The draft Greater Cambridge Local Plan and Policy H/MO
The draft Greater Cambridge Local Plan includes a dedicated policy on HMOs, known as Policy H/MO. This policy is expected to introduce concentration thresholds, limiting the proportion of HMOs permitted in any given area to protect the balance of residential communities.
While the plan is still progressing through its examination stages, landlords and investors should monitor its development closely. Once adopted, it could restrict new HMO conversions in already saturated streets, particularly in CB1 and parts of CB4.
The Renters’ Rights Act: what HMO landlords need to know
The Renters’ Rights Act is bringing significant changes to the private rented sector in England. The abolition of fixed-term assured shorthold tenancies means all tenancies will move to periodic arrangements, with tenants able to give two months’ notice to leave at any point.
For HMO landlords, this creates more fluid occupancy patterns and makes robust tenant referencing and room-by-room management even more critical. Grounds for possession have been reformed, and landlords will need to ensure their processes – from issuing notices to maintaining compliance documentation – are watertight.
Belvoir Cambridge is well-placed to help landlords navigate these changes across all property types, including complex multi-let arrangements.
Where HMOs still stack up commercially in 2026
Despite the compliance burden, well-managed HMOs in the right Cambridge locations continue to deliver strong returns. Here is how the key areas compare.
Romsey and Mill Road (CB1)
The Romsey area and the Mill Road corridor remain among the most commercially viable locations for HMOs in Cambridge. Strong demand from postgraduate students, young professionals, and NHS staff at Addenbrooke’s Hospital keeps void periods low and rents competitive.
Gross yields for compliant, well-managed HMOs in this area typically range from 7% to 9%, significantly outperforming standard single-let properties in the same streets. Article 4 restrictions apply here, so any new conversions require planning permission, but existing licensed HMOs can represent strong ongoing investments.
Cherry Hinton
Cherry Hinton has grown in appeal as renters are priced out of more central postcodes. Its proximity to the Biomedical Campus and good bus links into the city centre make it attractive to professional sharers.
HMO yields in Cherry Hinton are broadly comparable to Romsey, and the area sits within the additional licensing zone. Landlords operating here should ensure room sizes, fire safety, and management standards meet current requirements.
Arbury and Kings Hedges (CB4)
Parts of CB4, including Arbury and Kings Hedges, offer some of the most accessible entry points for HMO investment in Cambridge. Property values are lower than in CB1 or CB3, which supports higher gross yields for investors who manage compliance carefully.
Demand is driven by a mix of students at Anglia Ruskin University, key workers, and younger professionals. The trade-off is that tenant management in these areas can be more intensive, making professional lettings management a worthwhile consideration.
Prime CB3 and central Cambridge
In contrast, prime CB3 postcodes and the streets closest to the city centre tend to deliver lower HMO yields, often falling below 6% gross. High acquisition costs are the primary reason. While demand is strong, the numbers rarely justify the compliance costs and management complexity of an HMO over a standard let in these locations.
Key compliance checklist for Cambridge HMO landlords
Whether you manage one HMO or a portfolio across the city, the following points should be on your radar for 2026.
Confirm whether your property falls within the additional licensing designation and apply for or renew your licence accordingly. Check whether Article 4 applies to your postcode before making any changes to occupancy arrangements. Ensure room sizes meet the national minimum space standards introduced under the 2018 HMO regulations. Review fire safety provisions, including interlinked smoke alarms, fire doors, and emergency lighting where required. Update your tenancy agreements and management processes to reflect the Renters’ Rights Act changes. Keep records of all compliance documentation, inspections, and maintenance in a format that can be produced to the council on request.
Working with a local lettings specialist
Cambridge’s HMO market rewards landlords who stay ahead of regulatory changes and manage their properties to a high standard. It penalises those who do not. The combination of additional licensing, Article 4 directions, forthcoming Local Plan policy, and the Renters’ Rights Act means that the compliance picture is more layered than in most English cities.
Belvoir Cambridge works with landlords across all property types and portfolio sizes – from single HMOs to multi-property portfolios spanning CB1, CB4, and beyond. Our local knowledge of Cambridge’s neighbourhoods, planning history, and council enforcement priorities means we can offer genuinely practical guidance rather than generic advice.
