How High Street, Porthmadog prices moved
The chart tracks the median High Street, Porthmadog house price for every year with a recorded sale, from 1999 to 2005. 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 |
|---|---|---|---|
| 1990s | 1 | £46,000 | £102,142 |
| 2000s | 3 | £94,000 | £171,240 |
The highest yearly median on record for High Street, Porthmadog is £128,500 in 2005; the lowest is £46,000 in 1999. Across the full 7-year record the cash median has moved from £46,000 to £128,500.
In 2026 money that first median is worth £93,728, so the real change over the whole record is +149.8% — about +16.48% 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: +179.3% in cash against +149.8% 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 High Street, Porthmadog values — no mix of property types can flatter the number.

What sells here
The mix of property types explains a large part of any area's median. High Street, Porthmadog 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 |
|---|---|---|---|---|
| Terraced | 44 | 57.1% | £85,000 | £23,000 – £355,000 |
| Flat or maisonette | 25 | 32.5% | £150,000 | £40,000 – £280,000 |
| Detached | 4 | 5.2% | £185,000 | £25,000 – £212,000 |
| Semi-detached | 4 | 5.2% | £80,000 | £27,000 – £168,025 |
Section 06
Ownership and new build in High Street, Porthmadog
26 of the sales on record are leasehold and 51 freehold — 33.8% 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.
The median leasehold sale is £150,000 and the median freehold sale £88,000 — a gap of -41.3%. Most of that gap is property type rather than tenure itself: leasehold here is largely flats, freehold largely houses.
| Category | Sales | Share | Median paid |
|---|---|---|---|
| Leasehold | 26 | 33.8% | £150,000 |
| Freehold | 51 | 66.2% | £88,000 |
A further 35 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.
Section 09
How High Street, Porthmadog compares
The median across the whole archive is £157,500. High Street, Porthmadog sits below that national figure — -32.6%.
Within Porthmadog the street ranks 37 of 70 by median price, and its median is below the town figure of £126,500 (-16.1%).
Where an EPC floor area could be matched to the sale, the median works out at £1,908 per square metre, across 6 of the 77 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 £23,000 to £355,000. 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.

Quick answers
Common questions about this data
What is the average house price in High Street, Porthmadog?
The median price paid in High Street, Porthmadog across every sale on the register is £106,150. 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 High Street, Porthmadog?
77 sales are on record for High Street, Porthmadog, the most recent completing on 7 Nov 2025. Every one is a completed transfer lodged with HM Land Registry, not an asking price or an estimate.
Have High Street, Porthmadog house prices actually risen?
In cash, the median rose +179.3% between 1999 and 2005. In 2026 money — that is, after inflation — the change is +149.8%. Both numbers are true; only the second one tells you whether buying here preserved value.
When were High Street, Porthmadog house prices at their highest?
The highest yearly median on record is £128,500, set in 2005. 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 High Street, Porthmadog?
£1,908 per square metre, from the 6 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 7 Nov 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.
