Section 04
What sells here
The mix of property types explains a large part of any area's median. Lon Y Celyn, Treharris 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 |
|---|---|---|---|---|
| Semi-detached | 60 | 98.4% | £109,000 | £43,950 – £215,000 |
| Detached | 1 | 1.6% | £200,000 | £200,000 – £200,000 |
Section 06
Ownership and new build in Lon Y Celyn, Treharris
25 of the sales on record are leasehold and 36 freehold — 41.0% 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.
The median leasehold sale is £68,000 and the median freehold sale £129,975 — a gap of +91.1%. 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 | 25 | 41.0% | £68,000 |
| Freehold | 36 | 59.0% | £129,975 |
| New build | 1 | 1.6% | £46,000 |
| Existing home | 60 | 98.4% | £116,750 |
New builds sold for less than the median existing home — -60.6%. 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.
Section 09
How Lon Y Celyn, Treharris compares
The median across the whole archive is £157,500. Lon Y Celyn, Treharris sits below that national figure — -26.3%.
Within Treharris the street ranks 61 of 209 by median price, and its median is above the town figure of £84,200 (+37.8%).
No EPC floor areas could be matched to these sales, so no price per square metre is published here. An estimate would be a guess, and the archive does not publish guesses.
The full range on record runs from £43,950 to £215,000. 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.

Common questions about this data
What is the average house price in Lon Y Celyn, Treharris?

How many homes have sold in Lon Y Celyn, Treharris?
61 sales are on record for Lon Y Celyn, Treharris, the most recent completing on 23 May 2025. Every one is a completed transfer lodged with HM Land Registry, not an asking price or an estimate.

When were Lon Y Celyn, Treharris house prices at their highest?

How current is this data?
The latest sale shown here completed on 23 May 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.
