LL55 prices by floor area

| 1996 | £39,500 | £83,304 | 261 |
| 1995 | £39,000 | £84,780 | 216 |
In cash terms the typical LL55 home went from £39,000 in 1995 to £210,000 in 2026, roughly 5 times the price. Adjusted for inflation it still comes to a real rise of roughly 148%, so homes here got dearer in substance, not only in cash. In inflation-adjusted terms the high-water mark was 2022. The market now sits about 11% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the LL55 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 2003 (+44.7% on the year before); the weakest, 2009 (−5.1%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Growth per year, over one to twenty years
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | +2.4% | 0.0% |
| 5 years (since 2021) | +3.7% | −1.1% |
| 10 years (since 2016) | +3.4% | 0.0% |
| 20 years (since 2006) | +2.2% | −0.6% |
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.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of terraced homes dominate the record here, 45% of the typed total. In 2025, the last year both were recorded here, a detached home traded at £305,000 against £105,000 for a flat, 2.9 times the price.

The turnover behind the prices
How many homes change hands
Recorded sales per year. The dip after 2008 is the financial crisis; the last bar is still filling in as recent sales get registered.
The last five years, month by month
Monthly registrations. The sawtooth is seasonal; the register runs weeks behind completions at the right-hand edge.
LL55 recorded 216 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 345 sales a year before the financial crisis and 212 a year over the last five. Watch the volume as closely as the price. Thin years make jumpy medians, where one street's sales can move the figure, and the newest year is always incomplete because registrations trail completions by weeks or months.
The rental side of LL55
LL55 falls under Gwynedd, where the ONS puts the average private rent at £708 a month (May 2026 figures). Size sets most of the rent: one-beds average £548 a month here against £1,035 for four or more bedrooms.
Average monthly rent by size, Gwynedd
ONS Price Index of Private Rents, May 2026.
Set against the £210,000 median sold price, £708 a month is £8,496 a year, a gross yield of 4.0%: 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.

These asking prices come live from estate agents publishing feeds to HomesIndex, refreshed each Monday and Thursday. They are a sample of the market rather than its entirety, and an asking price is not a sale price.
Bedroom by bedroom: LL prices by size
What homes of each size actually sold for across the LL area, from the Land Registry record. Size steps are fiercely local. A third bedroom adds a quarter to the price in some areas and close to four fifths in others, which is why no national rule of thumb survives contact with a real market.
| Type | 1 bed | 2 bed | 3 bed | 4 bed | 5 bed |
|---|---|---|---|---|---|
| Detached | — | £217,000 | £310,000 (+43%) | £445,000 (+44%) | £580,000 (+30%) |
| Semi-detached | £160,000 | £180,000 (+13%) | £215,000 (+19%) | £276,000 (+28%) | £360,000 (+30%) |

| Flat | £98,000 | £145,000 (+48%) | £195,000 (+34%) | — | — |
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. Sizes with too few homes to be meaningful are left blank.
