Who is the cheapest gas provider in UK?

As of my knowledge cutoff in February 2022, the cheapest gas provider in the United Kingdom may vary based on your specific location and the provider's rates and deals at the time. However, some providers that frequently offer competitive gas rates include:

1. Octopus Energy: Octopus Energy has a reputation for offering competitive gas and electricity rates. They have a simple pricing structure and provide 100% renewable electricity.

2. Bulb: Bulb is another provider that often has competitive gas prices. They also have a focus on renewable energy and provide a carbon-offsetting option.

3. SSE: SSE (Scottish and Southern Energy) is a large energy provider in the UK that sometimes offers competitive gas rates.

4. E.ON Next: E.ON Next is another major UK energy provider that regularly offers competitive gas prices.

5. EDF Energy: EDF Energy is a French-owned energy provider that occasionally has competitive gas rates in certain areas.

It's important to note that energy prices can fluctuate, and the cheapest provider at one point may not be the cheapest at another. To ensure you get the best deal, it's a good idea to compare prices and plans from multiple providers using a price comparison website or by contacting the providers directly. Additionally, some energy providers may offer special deals or discounts to new customers, so it's worth checking those as well.
