SWALEC Customer Reviews

In general, SWALEC fares relatively well in terms of customer service but customers sometimes find the supplier expensive compared to others, which is a fair point. Insofar as SWALEC and SSE use the same customer service, have a look at our SSE customer reviews section to see what SWALEC customers have to say.


As an SSE trading name, SWALEC complaints performance is included in that of SSE. The supplier received 217,253 complaints in the first quarter of 2014, of which 82.11% were resolved by the end of the next working day. This is a relatively small number of complaints given SSE’s size compared to the other Big Six suppliers (except for Scottish Power) but SSE is not the fastest in complaints handling.

Who are SWALEC?

SWALEC is SSE’s trading name for Wales, like Scottish Hydro for Scotland and Southern Electric for Southern England.

Historically, SSE (Scottish and Southern Energy) is the result of the 1998 merger between the North of Scotland Hydro-Electric Board and the Southern Electricity Board. The SSE brand dates back to 2010. However, SWALEC was initially sold to British Energy (later bought by EDF Energy) in February 2000 before being purchased by SSE in August 2000 for £210 million.

SSE is involved in generation, distribution and supply. It employs 18,500 people with Alistair Phillips-Davies as its CEO. In 2013, SSE revenue was £28 billion, and the supplier provided electricity and gas to 9.6 million domestic and business customers.


As an SSE trading name, SWALEC uses the SSE fuel mix, which relies predominantly on coal (54%) and natural gas (28%), as shown in the chart below:
