St Austell, a town built on tin and china clay
St Austell is a town and civil parish in Cornwall. Its built-up area had 24,360 residents at the 2021 census. The town lies about 10 miles south of Bodmin.
St Austell was a village around its parish church until tin mining arrived in the 18th century. For example, the nearby Polgooth mine became known as the greatest tin mine in the world. China clay later took over from tin and copper as the main industry. The town became the centre of a large quarrying trade, with many clay works and spoil heaps.
The parish church is now dedicated to the Holy Trinity. Its current building dates from the 13th and 14th centuries, and it was extended in 1498 to 1499. Meanwhile, the Old Market Hall, built in 1844 in an Italian Renaissance style, still stands in the centre.
Local government and getting around
Two tiers of local government cover the town: St Austell Town Council and Cornwall Council. Therefore, any question about planning consent for an outdoor unit goes to Cornwall Council. Our planning permission guide explains the permitted development rules that usually apply.
The A390 bypasses the town to the south on its way from Liskeard to Truro. The A391 arrives from Bodmin, while the A3058 comes in from Newquay. St Austell railway station opened in 1859 on the hillside above the town centre.
Visitors come for the nearby beaches and the Eden Project. In particular, the Eden Project sits in a reclaimed china clay pit. The Lost Gardens of Heligan are also close by. Charlestown, with its harbour and dock begun in 1791, lies about 2 miles south-east of the centre.
What an installation here tends to involve
Every installation starts with a site visit. The installer looks at the wall construction, since an older solid wall needs different fixings from a modern cavity wall. They also plan where the pipe run will go, keeping it as short and tidy as possible.
Ground and access vary from one property to the next, whatever the setting. As a result, an installer checks where the outdoor unit can stand safely before work begins. A wall bracket suits a small yard, while a paved pad works for a more open garden. Typical prices for this kind of work appear in our 2026 installation cost guide.
The drain line and the cable need a neat route too. Nothing should be left trailing across a path, a step or a garden wall. Similarly, the unit should sit where its airflow is not blocked by fences or planting.
Refrigerant work must be done by an F-Gas certified engineer under UK law. Because of this, it is worth asking to see that certificate at the site visit. You can also ask how the installer plans to route the pipework on your home.
