SSE Swalec Gas & Electric Review

Swalec is SSE’s trading name for Wales and stands for South Wales Electricity. Its prices aren't famed for being the cheapest and it has come in for some criticism in the past. It has been an SSE brand for more than two decades, having been bought out by the energy giant in 2000. Could it surprise you? Read on to find out.

Swalec reviews

In general, Swalec fares very badly in terms of customer reviews, with customers complaining of being overcharged or their bill being much higher than quoted. As Swalec and SSE use the same customer service, you can take a look at our SSE reviews section to see what customers have to say about this. As a taster, though, here are a couple of real Swalec reviews of the kind of service it offers.

I live on my own. I use very little gas or electricity. SSE seem to be really keen to "help me" prepare for the winter months by building up £400+ credit on my account.

Frustrations run high when it comes to billing errors. The key to being a successful energy company in the UK is having accurate billing and clear communication about tariffs and policies with customers. It's not encouraging to see so many complaining that SSE gets this so very wrong.

Nor does the supplier seem to be making up for these errors in other areas. Another common complaint among SSE Swalec reviews seems to be that customers feel they're being made to wait too long over the phone:

I have been without electric for 10 days! I’ve called every single day and been on the phone for 1 hour plus at a time. Each time I get someone telling me something different.

With both of these reviews coming within the past couple of months, the outlook is worrying for prospective customers. This second review illustrates a few serious red flags - basic errors with service, poor customer service, and confusing processes. We would suggest avoiding providers like this if you don't want your energy supply to cause you any headaches.


As an SSE trading name, Swalec complaints performance is included in that of SSE. The supplier received 73,850 complaints in the second quarter of 2020 of which 72.90% were resolved by the end of the next working day. This is actually relatively small number of complaints given SSE’s size, and represents a big drop from previous periods, but the provider still has a little work to do to improve the speed of its complaints handling.

About Swalec

Swalec is SSE’s trading name for the Welsh market, like Scottish Hydro is in Scotland and Southern Electric is in Southern England. Before SSE came into the picture in 2000, Swalec was one part of the South Wales Electricity Board.

Is Swalec part of SSE?

Yes. According to the 2000 Ofgem report on the acquisition, SSE is a vertically integrated energy company that controls energy at various stages from production to supply. Swalec, on the other hand, operates primarily as a supply business through SSE (its parent company).

Swalec originally provided SSE with the tools for market penetration outside of its traditional areas of influence. This was crucial at the turn of the millennium, since the UK energy market was still undergoing deregulation and there wasn’t sufficient process maturity for customers to easily switch from their traditional regional energy suppliers.

Swalec’s first purchaser was actually Welsh Water, which had only recently become a private concern itself. The rationale behind the acquisition was being able to find market synergies between the two types of utility company: water and power. The Swalec brand outlasted the organisation in the sports arena, with the Swalec Rugby Championship being an ongoing example.

The SSE Swalec and Sophia Gardens

The Cardiff stadium inked a ten-year sponsorship deal with Swalec back in 2008 for £1.5 million. While it was initially called Swalec Stadium, the name changed to the SSE Swalec in 2015 to reflect SSE’s ownership of the company. In 2018, SSE chose not to renew the naming rights, which heralded the return of the stadium’s longstanding name.

The Glamorgan County Cricket Club calls the stadium home and the venue has hosted international cricket test matches since 1999. The stadium can welcome over 15,000 cricket fans for major sporting events such as the recent Cricket World Cup.

Swalec Tariffs & Prices

Swalec has the same set of tariffs as SSE: a standard variable plan, a one-year fixed plan, a two-year fixed plan, and a couple of specialised offers. In Wales, where Swalec operates, its prices are relatively high compared to other suppliers.

There is no difference in price between SSE's variable and one-year fixed plan, so you might say it's not worth signing up for the fixed deal. Remember, however, that the price of its variable deal is subject to change and it's always worth considering locking in a good price for as long as you can.

As we've mentioned, however, SSE Swalec tariffs are not particularly cheap - you can certainly find cheaper and more environmentally-friendly deals, often both together. Swalec's best tariff, for our money, is its specialist electric vehicle tariff - the SSE Fix and Drive tariff - which has the same rates as its standard and one-year fixed tariffs but includes 8,000 miles of free electricity when you charge your vehicle outside of peak hours.

SSE Swalec Fuel Mix

As an SSE trading name, SSE Swalec uses the SSE fuel mix, which relies on a mix of natural gas (48.1%) and renewable sources (51.9%), as shown in the table below:

- Coal Natural gas Nuclear Renewables Other
SSE Swalec average 0% 48.1% 0% 51.9% 0%
National average 3.9% 39.4% 16.6% 37.9% 2.2%

SSE is still to a large extent reliant on natural gas, though the rest it sources from renewables. Nowadays, green suppliers are able to buy clean and renewable electricity at competitive market rates, and plenty offer 100% green tariffs.

The excuse that renewables, such as solar, wind, tidal and hydro are expensive and impracticable is no longer valid in this day and age, so we see no reason an eco-conscious customer should settle for less than 100%.

The truth is that nowadays there are many alternatives that offer exactly the same electricity and gas as SSE Swalec, but for less money and from much greener sources. It’s worth checking out energy companies like Octopus and Bulb, among others, for these kinds of deals.
