Bethesda Property Market: House Prices, Sold Data & Development Finance, Q3 2026 Review

Bethesda: Slate quarry town near Zip World with growing adventure tourism employment.

The Bethesda property market recorded 1,824 residential sales in the 12 months to 30 June 2026, with a median sale price of £193,750. This places Bethesda £4k above the Gwynedd county median of £190,000, and £91k below the approximate UK median of £285,000.

Prices in Bethesda have shown modest growth, a year-on-year change of +2%. Within Gwynedd, Bethesda ranks 3rd by price out of 6 principal towns, and 1st by transaction volume.

On a quarterly view, Bethesda median prices moved from £188,500 in Q1 2025 to £200,000 in Q2 2026, a change of +6.1% over 5 quarters.

Bethesda shares a HM Land Registry reporting district with neighbouring towns, and the source data does not distinguish Bethesda-specific sales from the wider district. The figures above reflect the whole shared district rather than Bethesda alone.

Gwynedd, the local planning authority covering Bethesda, approved 11 residential planning applications and refused 2 in Q3 2026 (1 July to 30 September 2026), with 58 still awaiting a decision. Too few decisions were captured in the period to state a reliable approval rate. Planning figures come from local planning authority records compiled by Landstack, retrieved on 3 October 2026. Councils and Landstack can take several days to publish decisions, so decisions made in the final days of Q3 2026 may not all be included yet.

Schemes approved in Q3 2026, together with those still awaiting a decision, propose around 384 homes, an estimated £66.5m of development value at local sale prices. Treat the unit total as an upper bound, since an outline permission and its reserved-matters application both count.

Gwynedd covers more than one town in Gwynedd, so these figures are authority-wide rather than specific to Bethesda alone.
