What’s New

Version 1.41.0

A speedy update: we’ve removed the tools to refer your friends for now. While energy costs are so high we’re doing everything we can to keep prices as low as possible for our members. That means reducing marketing costs, like referrals. Keep an eye on our social media - we’ll share the news there when we bring it back.

In the meantime, if you’re on our smart charging trial you’ll see a new link in the ‘Car charger’ panel to tell us about any issues. Hopefully, you won’t even need it.

Love the moral reward

For us, the biggest motivation to join bulb was the peace of mind. They are by far the most accessible supplier of 100% renewable energy, in our experience.

There have been some pleasant discoveries since switching from one of ‘the big six’ that are outdated in their customer interactions (one specifically that I won’t mention here); the website alone is brilliant; the tools are simple and easy to navigate.
I regularly update my meter readings due to a rather (admittedly) weird fondness for dropping onto my account and seeing our usage and predictions for future consumption which are expressed in a chart (- this appeals to my almost fetish-like desire for such things).

Bulb are slightly more expensive than what we were paying but ultimately worth paying if it means delivery on promises for a cleaner, more responsible supply of our energy. What’s a ‘fiver’ in the grand scheme of things? Some maths whiz will point out that £5 x 12 = £60 over the year but again, we feel the ease of interaction with the company has been my best experience yet with an energy supplier and may the simplicity live long!

You will not regret becoming a member of this growing tribe.

App is not accessible with voice-over for the iPhone.

Hi, I have a new bulb customer, and I find the app is not accessible with VoiceOver on the iPhone. For any developer who doesn’t know, voice-over is the one and only screen reader for the iPhone. A screen reader convert text into speech so the blind people can use the iPhone and apps successfully. If apps are not correctly coded with accessibility in mind, the voice-over software built-in to all iPhones cannot use the app. This means that blind people cannot use the app successfully, and therefore locked them out of the service. Please test your app with voice-over for compatibility! For a customer facing app, this is disgraceful. Please fix this I am a new customer, and expect my apps to work with my screen reader. Please note, the Bulb website is pretty good with jaws for windows, but the app which is made for Apple devices, which only have one screen reader for them, should be compatible with that screen reader. I expect full compatibility within the next app, as Apple have a website dedicated to accessibility for web developers. This is within the SDK. Thank you.

Hi there,
The latest version of the app – 1.8.8 – should be fully compatible with VoiceOver, so please look out for an update. We released this yesterday, but releases are rolled-out gradually, so you should be offered an update in the next 7 days.
Our app, like the website, was designed to be fully accessible. Unfortunately some bugs had crept in recently that have meant VoiceOver hadn't been working. We're really sorry about that, these have been fixed in 1.8.8, and we've implemented new testing processes to ensure that doesn't happen again.
Please drop us an email at if you are having issues after the update, or if there is if you have any other suggestions on how we can better serve our members with accessibility needs.
Best, Team Bulb

Awful company

Ever since I joined Bulb I have had nothing but trouble with them where they can’t seem to get my bills accurate even though I have a smart metre. I have now been billed over £900 for energy usage from 16th May until 15th June even though it has been very hot so not had the heating on and it is light until gone 9.30 so not using much electricity. The bill also has a date of September 2020 even though it is June 2021 so they have charged me again for September last year!? I have gone into the app as wanted to talk to someone but that facility is currently not working, hasn’t been for months tbh, and noticed that I have had several statement corrections over the last few days so now don’t have a clue where I stand with what is owed to me. Joining this company has to be my biggest regret in life as all they seem to do is confuse you with the bills so they can defraud you out of money. I thought NPower was bad but bulb make them look brilliant. I would not recommend this company to my own worst enemy

Hi Mikey, I'm so sorry that you've had such a poor experience with Bulb. We absolutely need to have a thorough look into your billing and offer an explanation - please can you send us a DM with your account details so that we can get this sorted? Many thanks - Niamh
