Caerphilly against Porthmadog
Town guides for each: Mortgage advice in Caerphilly and Mortgage advice in Porthmadog.
Schools and families
Welsh schools are inspected by Estyn, which no longer gives a single overall grade, so the choice turns on catchment and the latest inspection reports.
A strong catchment in the cheaper town can cost more than an average street in the dearer one. Compare catchments, not averages.
Running costs and getting to work
Band D council tax is £2,077 in Caerphilly and £2,437 in Porthmadog, a difference of £360 a year.
The honest verdict
Porthmadog is cheaper to buy on these figures.
Neither is right in the abstract. If the deposit is your constraint, the £1,000 difference matters more than anything else here. If catchment is the constraint, price follows the school you need.

Porthmadog
In its favour- A characterful harbour town at the gateway to Eryri
- World-famous heritage railways & a National Rail station
- The Cob, the Glaslyn estuary & Portmeirion nearby

Best for Families ★★★★☆
