What buyers actually paid in IP20
The 2026 median for IP20 is £285,000, taken from 63 registered sales. The mean, which is what most sites call the "average house price", is £304,600, modestly above it, the usual shape of a market with an expensive tail.
House prices per square metre in IP20
The last five years of sales put IP20 at roughly £3,260 per square metre. That figure, built from each sale's Energy Performance Certificate floor area, is the one that makes a small flat and a big house comparable.
For scale: the England and Wales median is £285,000, so IP20 trades 0% above the country as a whole.
A typical IP20 home, priced year by year (1995 to 2026)
Year by year: the median as it was recorded, and the same figure brought into today's money with ONS CPIH, which is where "did homes get dearer" actually gets answered. Hover shows each year; the legend isolates a series.

In cash terms the typical IP20 home went from £60,000 in 1995 to £285,000 in 2026, roughly 5 times the price. Adjusted for inflation it still comes to a real rise of roughly 119%, so homes here got dearer in substance, not only in cash. In inflation-adjusted terms the high-water mark was 2021. The market now sits about 20% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the IP20 median
Each bar is the change on the year before, in cash. The zero line is the boundary between rising and falling.
The strongest year on record here is 2002 (+29.5% on the year before); the weakest, 1996 (−16.7%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of detached houses dominate the record here, 47% of the typed total. In 2025, the last year both were recorded here, a detached home traded at £350,000 against £138,000 for a flat, 2.5 times the price.

| Type | Median (2026) | Sales that year | All-time sales |

| Semi-detached | £275,000 | 16 | 1,538 |
| Terraced | £190,000 | 13 | 874 |

The long view: annualised growth
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 year (since 2025) | +5.6% | +3.1% |
| 5 years (since 2021) | +0.4% | −4.3% |
| 6 years (since 2020) | +2.6% | −1.8% |
| 10 years (since 2016) | +3.3% | −0.1% |
| 20 years (since 2006) | +2.7% | −0.1% |
Each row is compound annual growth of the median; ONS CPIH supplies the real-terms deflator. Annualising irons out the cycle, which the chart above shows in full, and past growth records what happened rather than predicting anything.
The turnover behind the prices
How many homes change hands
Each bar is a year's recorded sales. 2008's dip is the financial crisis, and the newest bar always grows for a while as late registrations arrive.
The last five years, month by month
Sales as they reached the register each month. Expect the seasonal sawtooth, and discount the newest months while late entries land.
IP20 recorded 114 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 178 sales a year before the financial crisis and 116 a year over the last five. Volume matters as much as price: when few homes change hands, the median gets jumpy and a single street can move the figure. The most recent year is always still filling in, because sales appear in the Land Registry weeks or months after completion.
How IP20 trades
Only 114 sales completed here in the last twelve months of data, which makes IP20 a thin market. Each figure rests on few transactions, so single streets can swing the median and the charts deserve a sceptical squint.
The rental side of IP20
The local authority for IP20 is South Norfolk, and its ONS average private rent currently stands at £981 a month (May 2026 figures). Size sets most of the rent: one-beds average £696 a month here against £1,574 for four or more bedrooms.
Average monthly rent by size, South Norfolk
ONS Price Index of Private Rents, May 2026.
Set against the £285,000 median sold price, £981 a month is £11,772 a year, a gross yield of 4.1%: gross, before letting costs, voids, maintenance and tax, so a ceiling rather than a promise. Rents are published at local-authority level, so nearby districts in the same authority share these figures.

No honest page predicts prices, so this one sticks to the record: the median is roughly flat over five years in cash but down 20% after inflation. Anyone weighing a purchase should read the volume chart with the price chart, remembering that these are completed sales, registered weeks after the deals were actually struck.
IP20's current homes for sale
Everything above is what homes in IP20 sold for. The live side of the market holds 83 homes at the moment, listed by 3 agents publishing to HomesIndex, at a typical asking price 7% above the IP20 median sold price.
Set against 114 registered sales in the last twelve months, the 83 homes on the market here are roughly 9 months of supply at last year's pace, and more in reality, since only agents who publish to HomesIndex are counted. A queue that long means homes are being offered faster than they are taken, and the pricing power sits with the buyer.
Of everything listed here, 14% asks less than the sold record of comparable homes. Each listing is compared with recent recorded sales of similar homes nearby.
- Sancroft Way, Wortwell, Harleston, Norfolk
- Old Post Office Court, Harleston
- Bullfinch Drive, Harleston
"Under comparable sales" means the asking price sits below what similar homes nearby actually fetched. Treat it as the start of a conversation, never a valuation, and always view the home.

Listed against sold: the IP20 mix
Sellers of detached homes in IP20 have company: 64% of current listings against 45% of recent sales. When a type is offered faster than it sells, the buyer usually holds the better hand.
| Type | Share of homes for sale now | Share of sales, 2024 and 2025 |
|---|---|---|
| Detached | 64% | 45% |
| Semi-detached | 36% | 32% |
| Terraced | 0% | 15% |
| Flats | 0% | 7% |
Listings are the homes agents publish to HomesIndex today; sales are HM Land Registry registrations. A listing whose type does not say detached, semi-detached, terraced or flat (a plain "house", a bungalow, a park home) is left out of the listing shares.
The IP20 sales calendar
March is when IP20 changes hands most (10.8% of the 711 sales dated 2021 to 2025); January is the quiet end at 6.9%. With so little between the busiest and quietest months, IP20 sells year round; the calendar is a weaker lever than price.
Sales by month, 2021 to 2025
| Month | Sales | Share |
|---|---|---|

| February | 59 | 8.3% |

Moving up a bedroom in IP: the cost
Real sold prices by size across the IP area, straight from the Land Registry record. The jump between sizes is local: in some areas a third bedroom adds a quarter to the price, in others nearly four fifths, so a national rule of thumb will mislead you here.
| Type | 1 bed | 2 bed | 3 bed | 4 bed | 5 bed |
|---|---|---|---|---|---|
| Detached | £270,000 | £303,250 (+12%) | £355,000 (+17%) | £442,550 (+25%) | £540,000 (+22%) |
| Semi-detached | £210,000 | £238,000 (+13%) | £268,500 (+13%) | £320,000 (+19%) | £400,000 (+25%) |
| Terraced | £161,000 | £205,000 (+27%) | £230,000 (+12%) | £280,000 (+22%) | £330,000 (+18%) |
| Flat | £125,000 | £157,000 (+26%) | £211,000 (+34%) | £290,000 (+37%) | £402,500 (+39%) |
Four years of recorded sales, split by built form and bedroom count. The register does not state bedrooms, so sizes come from each home's EPC record and a few homes will land one size out. Blank cells mean too few homes for the figure to mean anything.

About the numbers: everything is computed from HM Land Registry Price Paid Data (Crown copyright, OGL v3.0), geocoded to the address; today's-money figures use the ONS CPIH index, and rents are the ONS Price Index of Private Rents by local authority. These are medians of recorded sales, not valuations, and none of it is financial advice.
