Your postcode and your figures never leave this browser. If I cannot work out what you mean, those words are sent to be classified, and a bill photo goes only if you send one and confirm it. Nothing is stored either way. How that works.

| Property | Water | Sewerage | Total |
|---|---|---|---|
| one person | £230.59 | £336.61 | £567.20 |

Where this comes from, and where it could be wrong
Every figure is read from South West Water's own charges scheme for 2026/27, twice, and only published where both readings agreed. Your actual bill depends on how much water you use and whether you have a meter, which is why the calculator on the charges page does the arithmetic.
Worth knowing about South West Water
These are the dual service figures, for a household taking both water and sewerage from South West Water. A customer taking only one of the two services pays more. The single service water standing charge is £90.93 and the single service sewerage standing charge is £121.34 with surface water or £88.08 without.
The sewerage figures shown are the rates for a property that does drain surface water to the sewer, which is the ordinary case. The foul only rates are given alongside.
Surface water is already inside the sewerage rates above, which are the with surface water column. It is not a separate line to add on. The £112.27 in the scheme is the tariff for a property that receives surface water drainage and nothing else, and the £132.09 alongside it is the single service version of the same thing.
Unmetered sewerage standing charges are banded by rateable value. The figures shown are for a property up to £50 rateable value. Above £50 it is £223.00 with surface water or £189.74 without.
Unmetered sewerage without surface water is £4.7300 per £ of rateable value.
Highway drainage is not a separate line. Section 6.17 puts it inside the variable sewerage charges.
South West Water does not use the words standard and single occupier. It publishes occupancy bands, shown above as printed.
