How much is a new boiler in Swansea?

The average cost of a premium gas boiler in Swansea is £2,196 including installation. However, it should be noted that the majority of properties in the Gower aren’t connected to the mains gas grid*. As these properties cannot have a gas boiler, an alternative boiler will need to be considered. Oil boilers are the most popular choice for homes not connected to the mains gas grid, the average cost of an oil boiler in Swansea is £4,978.

*According to data from the Office for National Statistics 2011 Census

Is Swansea a hard water area?

No, Swansea doesn’t have hard water. It is amongst the 40% of locations in the UK that is categorised as having soft water. Supplied by Dŵr Cymru Welsh Water, the water in Swansea contains low levels of calcium carbonate and magnesium. This means that no water softeners and hard water filters need to be installed in properties in this area.
