How Marconi Avenue, Penarth prices moved
The chart tracks the median Marconi Avenue, Penarth house price for every year with a recorded sale, from 2001 to 2025. The dashed line restates each year in 2026 money, so the two lines separate exactly as much as inflation has eroded the cash figure.
| Decade | Years with sales | Median paid | In today's money |
|---|---|---|---|
| 2000s | 6 | £198,000 | £360,698 |
| 2010s | 3 | £233,500 | £329,235 |
| 2020s | 2 | £250,000 | £255,435 |
The highest yearly median on record for Marconi Avenue, Penarth is £282,475 in 2025; the lowest is £150,000 in 2001. Across the full 25-year record the cash median has moved from £150,000 to £282,475.
In 2026 money that first median is worth £294,159, so the real change over the whole record is -1.9% — about -0.08% a year after inflation. Cash growth and real growth are not the same story, and the gap is the part most price reports leave out.
Over the last decade alone the difference is stark: +15.3% in cash against -19.2% once inflation is removed. A buyer who sold at the end of that decade would have needed the real figure, not the headline one, to know whether they had actually gained.

The most recent sales
Every row is a completed sale as lodged with HM Land Registry. The right-hand column restates the price in 2026 money, which is the only fair way to compare a sale from the 1990s with one from last year.

Homes that sold twice
These addresses appear in the register more than once, so the same bricks are being priced twice. That makes them the strongest evidence of what actually happened to Marconi Avenue, Penarth values — no mix of property types can flatter the number.

Section 04
What sells here
The mix of property types explains a large part of any area's median. Marconi Avenue, Penarth is dominated by the type at the top of this table, so its overall median leans that way.
| Property type | Sales | Share | Median paid | Range |
|---|---|---|---|---|
| Flat or maisonette | 162 | 100.0% | £200,000 | £92,000 – £850,000 |
Section 06
Ownership and new build in Marconi Avenue, Penarth
162 of the sales on record are leasehold and 0 freehold — 100.0% of the market. Tenure is not a detail: a leasehold flat and a freehold house are different assets, and mixing them into one median hides the difference.
| Category | Sales | Share | Median paid |
|---|---|---|---|
| Leasehold | 162 | 100.0% | £200,000 |
| Freehold | 0 | 0.0% | — |
| New build | 66 | 40.7% | £157,500 |
| Existing home | 96 | 59.3% | £220,000 |
New builds sold for less than the median existing home — -28.4%. A new-build premium is normal: the buyer gets a warranty and nothing to fix, and the price is set by a developer rather than negotiated between two households.
A further 3 transfers for this area are on the register but are left out of every figure above. HM Land Registry marks them as additional price paid entries: repossessions, buy-to-let portfolio moves, transfers between companies or family, and sales at a discount such as right to buy. They are real records but they are not open-market prices, and including them would drag the median somewhere no buyer ever paid.

Living in Marconi Avenue, Penarth
Every certificate carries an energy efficiency band as well as a floor area. Across Vale of Glamorgan, 46.0% of 63,615 certificates sit in bands A to C, and 4.1% in F or G — the bands that cost the most to heat and are hardest to mortgage.
| Energy band | Certificates | Share |
|---|---|---|
| A | 576 | 0.9% |
| B | 8,073 | 12.7% |
| C | 20,598 | 32.4% |
| D | 23,546 | 37.0% |
| E | 8,216 | 12.9% |
| F | 2,038 | 3.2% |

The Office for National Statistics puts the mean private rent in Vale of Glamorgan at £985 a month as of Jun 2026 — £729 for a one-bedroom home and £999 for three bedrooms.
Against the median sale of £200,000 here, that rent is a gross yield of 5.91% a year. It is a measured figure rather than an assumption: a real local rent over a real local price, before any cost of ownership.
Police forces publish every recorded street-level crime. Within a mile of the centre of CF64, 107 crimes were recorded in Jun 2026: 40 violent, 4 burglary, 5 vehicle-related and 10 anti-social behaviour. The median postcode district in this archive recorded 167 in the same month, so this one is 1.6 times quieter.
Against the 131,939 residents the 2021 census counted in Vale of Glamorgan, that is 0.81 recorded crimes per thousand people in the month. The count covers a mile around the district centre while the population covers the whole council, so read the rate as an order of magnitude rather than a precise figure.
A count is not a rate. A district with shops and a station records more crime than a residential one of the same size, because more people pass through it. Read this next to the median, not on its own.

The neighbourhood around Marconi Avenue, Penarth
The 2021 census counted 131,939 residents in Vale of Glamorgan across 57,449 households. 72.1% of those households own their home and 27.9% rent — a split the sold record cannot show, because only owners appear in it.

Within Penarth the street ranks 200 of 381 by median price, and its median is above the town figure of £179,000 (+11.7%).
Where an EPC floor area could be matched to the sale, the median works out at £2,952 per square metre, across 63 of the 162 sales on record. Price per square metre is the only figure that compares a two-bed flat with a four-bed house honestly.
The full range on record runs from £92,000 to £850,000. Extremes usually mean something unusual — a plot sold without a house on it, a transfer between family members, or a very large property — so the median is the number to trust.
Marconi Avenue, Penarth sits in Vale of Glamorgan, in Wales.
The Office for National Statistics puts the median home in Vale of Glamorgan at 7.9 times median local earnings of £35,204 a year, measured to Sep 2025.

Quick answers
Common questions about this data
What is the average house price in Marconi Avenue, Penarth?
The median price paid in Marconi Avenue, Penarth across every sale on the register is £200,000. The median is used rather than the mean because a handful of very large sales would otherwise drag the average away from what a typical buyer paid.
How many homes have sold in Marconi Avenue, Penarth?
162 sales are on record for Marconi Avenue, Penarth, the most recent completing on 19 Dec 2025. Every one is a completed transfer lodged with HM Land Registry, not an asking price or an estimate.
Have Marconi Avenue, Penarth house prices actually risen?
In cash, the median rose +15.3% between 2013 and 2025. In 2026 money — that is, after inflation — the change is -19.2%. Both numbers are true; only the second one tells you whether buying here preserved value.
When were Marconi Avenue, Penarth house prices at their highest?
The highest yearly median on record is £282,475, set in 2025. That is the cash figure; measured in 2026 money the peak may fall in a different year, because inflation reshapes the series.
What is the price per square metre in Marconi Avenue, Penarth?
£2,952 per square metre, from the 63 sales where an EPC floor area could be matched to the address. Price per square metre strips out size, so a flat and a house can be compared on the same basis.
How current is this data?
The latest sale shown here completed on 19 Dec 2025. HM Land Registry publishes Price Paid Data monthly and a sale can take a month or two to appear after completion, so the most recent weeks are always incomplete.
