TA postcode district map, Taunton

Where the TA districts sit

2 districts are plotted without a label where labels would overlap; every one is in the table below.

Where TA sits

It falls across Somerset, Dorset and Devon.

Water supply across TA

All 24 TA districts are supplied by Wessex Water. That makes TA simple in a way many areas are not: one company, one set of rules, one status to check.

Wessex Water has a hosepipe ban in force from 18 August 2026, covering the whole of TA.

The shape of the TA area

TA6 is the largest district with 1,410 postcodes around Bridgwater, and TA15 the smallest with 25. The area divides into 66 postcode sectors.

Several districts share a settlement, which is a common source of confusion when a form rejects an address: TA1, TA2 and TA3 all point at Taunton, TA5, TA6 and TA7 all point at Bridgwater and TA12, TA13 and TA14 all point at South Petherton.

What borders TA

TA sits next to BA (Bath) to the east, EX (Exeter) to the west, BS (Bristol) to the north east, DT (Dorchester) to the south east and CF (Cardiff) to the north.

Its neighbours run in 5 different directions, so TA is landlocked by other postcode areas on most sides.

TA districts, settlements and water supply

Principal settlement is the town or city each district sits in or nearest to, derived from OS Open Names. It is not the Royal Mail post town, which is licensed data and not published openly. Status is resolved live from each company’s own notice.

Water hardness in TA

Figures are in milligrams per litre as calcium carbonate, the unit UK water companies report in. 23 of 24 districts have a published figure.

Descriptions such as very soft, soft, moderately hard, hard, very hard are the water industry scale: very soft below 75, soft 75–125, moderately hard 125–250, hard 250–375, very hard above 375 mg/l. Your supplier may use a different scale for the same number.

Hardness is published per census area, not per postcode, so these figures characterise a district rather than measuring one address. They are a scale and taste matter, not a safety one. Hardness data version wessex-water@2022-2025+yorkshire-water@2026.
