My Review

I reviewed all of the Energy Suppliers in the UK that I know and British Gas ranked #6 on that list. My review was based upon four criteria; 

  • Cheap prices
  • Ethical Practices
  • Ease of Communication
  • Problem-solving

Here’s my review of British Gas;

Cheap Prices

British Gas prior to the introduction of their Lite product, were consistently the cheapest. Since Lite was introduced, British Gas standard prices have increased a lot. Very rarely are British Gas in the top 5 cheapest suppliers. Their prices are expensive now.

Ethical Practices

British Gas often get a bad rep since they are so large that most people have had some sort of interaction with them. I can only speak of them post 2014, which is my experience with them. They generally speaking have many practices that most suppliers don’t.

They offer a 30 day backdate for customers who end up on out of contract prices. This used to be an unlimited backdate, but they’ve now limited it. They accept domestic meters as long as the customer can provide proof they are a business. British Gas also accept related meters and also offer customers with multiple meters can have their termination dates aligned together (known as co-terminus end dates).

In terms of unethical practices, British Gas are well known to undercut their brokers and treat them badly. They will often call a brokers clients and offer them an expensive contract many months before the contract was due to end. Not great.

They do not accept cash & cheque options anymore, which is terrible for many customers. I never understand why large suppliers would refuse cash/cheque/bacs payments. Many businesses prefer to pay on receipt of bill and not via direct debit, especially those with multiple sites. They’ve also rolled back their renewable energy offer and now only offer it to select businesses.

Ease of Contact

British Gas used to be easy to contact but now even their main standard service have scaled back communication. They don’t support email communication anymore. They are easily contactable on twitter and their twitter team is fantastic. Contacting them by phone is doable but painful, many of their customer service agents are foreign based and English can be a challenge.

Problem Solving

British Gas are slow to deal with issues but they do always deal with them. I very rarely have to get the Ombudsman involved. Getting to their complaints team is difficult and painful but once you’re with them, they are great. It’s been two years that I buy everything I need on the Internet. It saves a lot of time which I can spend with my kids. The online pharmacy I buy from is called It has the broadest selection of brand and generic tramadol sold at reasonable prices. The customer support and the delivery service are very professional. The Complaints Mangers know what they are doing.
