St Austell is a town and civil parish in Cornwall, 10 miles south of Bodmin and 30 miles west of the Devon border. At the 2021 census the parish had 20,985 people and the built-up area 24,360. It was the centre of a large china clay quarrying industry, with many clay works and spoil heaps around it, and Wikipedia still describes it as the main centre of the china clay industry in Cornwall.
We are a broker, not a lender. We arrange business mortgages for limited companies buying or refinancing the premises they trade from in St Austell. This is commercial finance on a trading company's own building, not a residential mortgage.
Which St Austell businesses buy premises with an owner-occupier mortgage?
Industry here starts with clay. Wikipedia records that the china clay industry employed around 2,200 people as of 2006, with sales of £195 million. That base supports engineers, hauliers, plant hire firms and maintenance contractors, the kind of companies that buy industrial units and yards on the edge of town.
The town's other well-known name is St Austell Brewery, which celebrated its 150th anniversary in 2001 and supplies cask ale to pubs across Cornwall and beyond; its visitor centre is on Trevarthian Road. Tourism is increasingly important too. The Eden Project, built in a former clay pit, the Lost Gardens of Heligan and the China Clay Country Park draw visitors, and the town has public houses, high street retailers and independent shops, many catering for tourists.
Pubs, cafés and hotels are assessed as trading businesses at indicative rates of 7.0 to 9.0% a year, subject to status, accounts and valuation. Our page on owner-occupier mortgages covers shops, offices and units.

A figure of 2.0x means the trade makes up twice the share of local businesses that it does across the UK.
St Austell's figures are those for the Cornwall Council area, 29,950 business units. The clay country shows in the data: other mining and quarrying runs at 3.59 times the UK share. Manufacturing and engineering make up 4.7% of firms, slightly above the 4.3% national figure, and construction 13.9%. These are businesses that need yards, workshops and plant storage, and owning the site guards against losing it at lease end. Valuers look closely at heavy-industry sites for contamination and alternative use.
How does the Cornish Main Line affect business property finance in St Austell, UK?
St Austell station opened in 1859 on the hillside above the town centre and sits on the Cornish Main Line, known locally for its viaducts across the Gover Valley and Trenance. Branch lines were built west of the town to serve the clay industry, and part of the line towards Newquay is still open. Radio St Austell Bay broadcasts from Tregorrick Park, one of the town's business locations.
For a lender, the main question is how easily a building could be used by another business. Clean units and town-centre shops are straightforward; former clay-industry buildings or sites with contamination history need closer investigation by the valuer and solicitor, which can affect the loan to value.

Industrial units across Cornwall rose 11.8% between 2016 and 2026 to 7,780, and they average just £16,400 in rateable value. Offices grew 19.4% but average only £9,400. For a business buying a unit on Bojea, Carclaze or a similar estate, those low values mean a smaller loan and a smaller deposit to find.
What does a commercial property loan in St Austell need in cash?
Lenders active in owner-occupier lending typically advance 70 to 75% of the price or valuation, whichever is lower, at an indicative 6.0 to 7.5% a year over 5 to 25 years, with arrangement fees of about 1 to 2%, subject to status, accounts and valuation.
HMRC charges non-residential SDLT at 0% up to £150,000, 2% from £150,001 to £250,000 and 5% above £250,000 (rates as at October 2026; check the current rates before you buy).
Illustrative example. A plant maintenance firm buys a freehold workshop for £275,000. A 75% loan is £206,250 and the deposit £68,750; SDLT is £3,250, so it needs about £72,000 before fees. See our guide to commercial stamp duty and the Cornwall business mortgages page.
Commercial lending to a limited company is unregulated and falls outside the FCA's regulated mortgage perimeter. Where a deal would be regulated, for example lending to a sole trader or individual, or a property where the borrower or a close family member will live in part of it, we refer it to an appropriately authorised firm.
Where St Austell companies buy premises
Town centre
The centre holds high street retailers, independent shops, pubs and the St Austell Market House, home to a small museum. East Hill and Market Hill carry reminders of the brewery's early history. Retailers and hospitality operators buy period buildings here, often with upper floors.
Trevarthian Road and the brewery
The present St Austell Brewery site, with its museum and visitor centre, sits on Trevarthian Road. Suppliers to the brewing and pub trade, from drinks distribution to maintenance, are among the businesses that look for nearby premises.
Tregorrick Park
Tregorrick Park is home to the studios of Radio St Austell Bay. Media, office and service businesses that want modern space outside the centre are typical occupiers, and a newer building can be simpler for a lender to value.
Clay country to the north
North of the town, the former clay pits and spoil heaps include the China Clay Country Park, two miles away. Clay-industry suppliers, engineering firms and hauliers buy yards and industrial buildings in this area, where environmental checks are often part of the legal work.
Eden Project and Heligan
The Eden Project, in a former clay pit, and the Lost Gardens of Heligan draw visitors to the area. Cafés, shops, accommodation and attractions nearby trade off that footfall, and lenders will study how seasonal the income is.
