Rent in Cardiff: Average Rents, Costs and What to Check

Rent in Cardiff has climbed to an average of £1,157 a month, and it keeps rising faster than the Welsh average. That figure comes from the Office for National Statistics (ONS), the most reliable public source. It helps you set a realistic budget before you start viewing flats.

This guide uses ONS numbers rather than advertised asking prices. It shows what rent in Cardiff looks like by bedroom, how much income you need, which Welsh rules protect tenants and what to check before you pay a holding deposit.

Key takeaways

• The average private rent in Cardiff is £1,157 a month in the latest ONS data we checked.
• Wales averages £836 a month, and the UK average is £1,383, so Cardiff sits between the two.
• By bedroom, averages run from £894 for one bedroom to £1,679 for four or more.
• Wales caps holding deposits at one week’s rent, and tenants cannot be charged setup fees.

What is the average rent in Cardiff?

ONS publishes the Price Index of Private Rents, which tracks what tenants actually pay. For Cardiff, the average monthly rent is £1,157. Last year the figure was about £1,119, so the rise is roughly 3% to 4% depending on the month measured.

Consequently, renting in Cardiff costs about £320 a month more than the Welsh average. However, it still costs less than the UK average, which London pulls upward.

Rent in Cardiff by number of bedrooms

ONS also splits the Cardiff average by property size. The mean rents below come from the same index.

Sharers can use this table to divide the cost. For instance, a three-bedroom home at £1,186 works out at about £395 each for three people, before bills. That is cheaper than the single-person price of a one-bedroom flat.

Why rent in Cardiff differs by area

ONS publishes rents for the whole Cardiff council area. It does not publish a reliable average for each postcode or street. Therefore, any site that quotes an exact “average rent for CF11” is using its own listings, not official statistics.

Even so, you can predict price patterns by looking at what each area offers.

Furthermore, property type matters more than the postcode label. A small flat beside the Bay can cost less than a large terraced house in a popular suburb.

How much income do you need to rent in Cardiff?

Many landlords and agents expect your income to cover rent several times over. A simple affordability rule says rent should take no more than 30% to 35% of gross income. Use the average rent to see what that means.

1. Take the average rent of £1,157.
2. Multiply by 12 to get £13,884 a year.
3. Divide by 0.30 to see the income that keeps rent at 30%: about £46,280.
4. Divide by 0.35 for a looser limit: about £39,670.

Importantly, individual landlords set their own rules, and referencing varies. If your income falls short, a guarantor or a house share can help.

What else do you pay on top of rent in Cardiff?

Rent is only part of the monthly cost. Tenants also pay for several bills, and the list depends on the contract.

• Council tax: Usually paid by the tenant, unless the home is a student-only property.
• Energy: Gas and electricity, unless the rent includes bills.
• Water and broadband: Often set up by the tenant.
• Contents insurance: Optional but sensible.
• Deposit: One payment, held in a protection scheme.

As a result, a cheaper listing with no bills can cost more than a dearer one that includes them.

Welsh renting rules every tenant should know

Wales has its own rules, and they differ from England. The Renting Homes (Wales) Act changed tenancies into occupation contracts, and tenants became contract-holders.

• Fees ban: Landlords and agents can charge only permitted payments. These include rent, a security deposit, a holding deposit, default payments, council tax, utilities and communication services.
• Holding deposit cap: A holding deposit cannot exceed one week’s rent.
• Security deposit: Published guidance states that Wales has no fixed national cap, unlike England. Ask what the landlord requires and compare it with the rent.
• Deposit protection: Landlords must protect the deposit in an approved scheme.
• Licensing: Landlords and agents in Wales must register or hold a licence through Rent Smart Wales.
• Rent increases: Landlords normally need to give notice, and they cannot raise rent more than once every 12 months unless the contract allows it.

Checks before you pay a holding deposit

1. Confirm the landlord or agent is registered with Rent Smart Wales.
2. Ask for the full list of costs in writing, including the deposit.
3. Check the energy rating of the property to estimate bills.
4. View in daylight and test water pressure, heating and mobile signal.
5. Read the contract before you sign, and ask about break clauses.
6. Photograph the property on the day you move in.

How to find rent in Cardiff that fits your budget

Search by bedroom count first, then compare three listings in the same area. If two of the three sit well above the ONS average, expect competition. Meanwhile, searching a little further out along a train line can lower your cost without lengthening your commute much.
