On ValuQ, the median completed sale price for a flat on Mount Stuart Square, Cardiff CF10 was £189,500. These figures come from 6 completed sales registered with HM Land Registry in the last 24 months, with floor areas from the energy certificate register. Asking prices are never used, and ValuQ last checked these figures on 25 October 2026.

Each property type on Mount Stuart Square has its own figures in the table below, so compare your home with sales of the same type and size.

For a figure for your own home, ValuQ asks local estate agents who cover CF10 to value it. Each valuation comes from a local estate agent who knows the street, and there is no AI in it. Agents respond within 48 working hours, and you see every response side by side on one screen before speaking to a single agent. It is free for homeowners, always, and agents never get your details until you choose.

If your home is already on the market, you can get a second opinion: competing local estate agents value your home side by side. Getting valuations does not change your current contract. Instructing a new agent during a sole-agency tie-in can mean paying two fees, so check your contract first.

How these figures are worked out

Every price here is a completed sale registered with HM Land Registry; asking prices are never used. Floor areas come from each home's energy performance certificate, and the price per square foot is the price paid divided by that floor area. Choose any sale to open that home's page.

Sold prices show what homes have sold for, not what any one home is worth today. Condition, extensions and the plot all move a price, and only a local agent who has seen the home can allow for them.
