Steady prices, rising rents

Cardiff goes into 2026 as one of the most resilient property markets in Wales. The average home now sits around £271,000, up a modest 1.2% on the year - a market that has cooled from the rapid rises of a few years ago into something far steadier. Rents tell a livelier story: the average private rent has reached £1,157 a month, up 3.9% year on year, as tenant demand continues to outstrip the supply of good-quality homes.

For HMO investors and landlords that combination matters. Slower capital growth keeps entry prices sensible, while strong rental growth and a deep pool of sharers support the per-room income model that HMOs rely on. The catch is regulation: Cardiff has tightened the rules around where and how new HMOs can be created, so the winners are increasingly the well-located, well-run, fully-compliant properties.

By neighbourhood

Where the renters are

Cardiff is really several rental markets in one city. Tap an area to see who rents there and the indicative room rents we're seeing.

Who rents here

Undergraduates

The heart of Cardiff's student HMO market, within walking distance of Cardiff University's main campus. High turnover but consistently strong demand on an academic-year cycle.

Students & young professionals

Around Albany Road and City Road, this is a mixed market of older students, postgraduates and young professionals who want a livelier, more independent neighbourhood.

Indicative room rent£575 - £725per room, per month
Who rents here

Professional sharers

Close to the University Hospital of Wales (the Heath), popular with nurses, medics, NHS staff and postgraduates - typically quieter, longer-staying professional sharers.

Who rents here

Young professionals

Newer and higher-spec stock around the city centre and Cardiff Bay. Fewer traditional HMOs, but professional house-shares here command the top of the room-rent range.

Know the rules

How Cardiff's HMO rules have tightened

The regulatory backdrop is the single biggest thing that separates a good Cardiff HMO buy from an expensive mistake. Here's the timeline that shapes the market today.

  1. 2016

    C4 use class introduced in Wales

    Wales created the C4 small HMO class without a permitted development right to reach it, so converting a standard home (C3) to a small HMO (C4) needs planning permission everywhere in Cardiff.

  2. 2018

    England widened licensing — Wales did not

    England removed the three-storey condition for mandatory HMO licensing. Wales kept it, so in Cardiff mandatory licensing still requires three storeys or more, five or more occupants and two or more households.

  3. 2021-23

    Additional licensing renewed

    Cardiff's additional licensing schemes (covering smaller HMOs in Cathays, Plasnewydd and Roath) were renewed - bringing many 3 and 4-person shares into licensing.

  4. Dec 2022

    Renting Homes (Wales) Act

    Tenants became 'contract-holders' on 'occupation contracts'. No-fault possession moved to a six-month notice under Section 173, with fitness-for-human-habitation duties on landlords.

Schemes and thresholds change. Always confirm the current planning position, licensing scheme and fees directly withCardiff Counciland your Rent Smart Wales obligations before committing.

The takeaway

What 2026 means for you

If you're investing

Steady prices and rising rents make Cardiff attractive, but planning means the value is in already-consented, well-located HMOs. Buy on fundamentals - location, room count and compliance - not just headline yield.

See HMOs to buy

If you're a landlord

With rents up nearly 4%, a well-managed, fully-compliant property is outperforming. Now is the time to review rents, tighten compliance and make sure your Rent Smart Wales and licensing position is watertight.

Book a rent review

If you're selling

Demand for turnkey, income-producing HMOs is strong. A property with clean licensing, good EPCs and proven rents will attract serious investor buyers - presentation and paperwork both matter.

Common questions

Cardiff HMO market FAQs

Do I need planning permission for an HMO in Cardiff?

Yes, everywhere in Cardiff. Since February 2016, converting a standard home into a small (C4) HMO requires planning permission across the whole city, because Welsh permitted development does not allow the C3 to C4 change anywhere. Unlike England, this does not depend on an Article 4 Direction. What varies by ward is the HMO density threshold that decides whether permission is granted. Always confirm the current position with Cardiff Council before you buy.

Does my Cardiff HMO need a licence?

In Wales, mandatory licensing applies only where a property has three storeys or more, five or more occupants and two or more households — all three conditions. England dropped the storey test in 2018; Wales did not. Cardiff's additional licensing schemes can bring smaller shares (three or more occupants) into licensing in certain wards. On top of that, all private landlords in Wales must register and be licensed with Rent Smart Wales.

What gross yield do Cardiff HMOs achieve?

Because rent is charged per room, a well-run Cardiff HMO usually targets a higher gross yield than a comparable single let. The actual figure depends on the purchase price, the number of lettable rooms, void periods and running costs. Use the calculator on this page as a starting point, then speak to us for property-specific numbers.

Is student and professional demand in Cardiff still strong?

With more than 42,000 students across Cardiff University, Cardiff Metropolitan University and the University of South Wales, plus steady professional in-migration to areas like the Heath and Cardiff Bay, demand for good-quality shared housing remains robust.

What changed under the Renting Homes (Wales) Act?

Since December 2022, tenants are 'contract-holders' on 'occupation contracts'. No-fault possession now uses a six-month notice under Section 173 rather than the old Section 21, written statements of the contract are required, and homes must meet fitness-for-human-habitation standards.
