A Guide to swapping to (renewable) energy suppliers and saving yourself some ££!

Changing energy suppliers, or changing anything for that matter can feel like a daunting task. Rest assured I have wrote this post to help make the swapping to a cheaper (and greener) energy supplier as easy as possible.

First of all, lets remind ourselves of why it is important to look into switching energy suppliers. The best excuse to swap energy suppliers is because you can save yourselves £100s by changing to a cheaper energy tariff (and supplier).

A lot of people believe that because they got the best deal when they switched energy, that they will continue to be on the best deal the following year. But it just doesn’t work like that. Energy suppliers know that people don’t like the hassle of changing suppliers, so they actually charge their most loyal customers the most and offer deals to new customers to get them to be supplied to them as they know they will be likely to stay with them for a long time.

Other people think that because they are on a pre-payment meter, they are unable to swap energy suppliers, which is incorrect, as I have changed my energy suppliers twice whilst being on a pre-payment meter. In fact, if you are on a pre-payment meter you should be more inclined to change energy suppliers as pre-payment meter customers often pay the highest for their energy just because it is ‘pre-payment’. So unfair I know, but there is hope because you can change energy suppliers (yay).

So, it is imperative that you spend some time looking into the best energy tariffs for you. It is also important to note that just because you have gone on comparison websites, does not mean that you have found the cheapest energy tariff for you. Many of the smaller companies, such as renewable energy companies have much cheaper tariffs than the ones on comparison websites, and this is because once built; renewable energy costs less to run than other energy sources. Renewable energy suppliers are also passionate about the environment, so they have cheaper tariffs to encourage more people to opt for a greener energy supply.

How to Swap Energy Supplier..

Step 1: Find out the details of your current energy supplier

If you do not yet know who your energy supplier is, I would recommend you first check out this post about how to find out who your energy supplier is, and then come back to this post when you have figured out who it is.

When looking into this, please get a piece of paper & pen and write down the following: you find out, make sure you write down all of the following:

  • your energy supplier’s name (e.g EDF)
  • the energy tariff you are on (e.g ‘Standard Variable)
  • the payment method (prepayment/direct debit)
  • the unit rate for your energy (e.g 14.810p per kWh) – find out what it is for each your gas and electricity supply (as these will be different)
  • the standing charge (e.g 30.42p per day) – find out what it is for each your gas and electricity supply (as these will be different)
  • the exit fees – if there are any (e.g £0)
  • your annual energy projection or actual energy usage (in KWh and/or £)
  • the energy MPRN (Meter Point Reference Number) (e.g 0123456789) or MPRN (Meter Point Administration Number) (e.g see the photo below)

Step 2: Get new energy quotes from a variety of sources

In order to get the best price for energy supply to your home, you will need to shop around. To save you time, I have listed the top sites to go onto for energy quotes, based on the significant amount of money these sites have saved me on my energy in the past and also based on the ease of use of these sites.

1) CompareTheMarket.com

CompareTheMarket is a useful comparison website that can be used for comparing anything from your energy supply to insurance for your car or home. In this case, it is my go to site to get an idea of the going rate for my energy supply. I have on 2 occasions used the site to complete my energy switch as well and the switch has been seamless, encountering no problems.

When I plugged my details into CompareTheMarket for my electricity only supply, it came out saying that Bulb energy is the cheapest energy supplier for my home (of the energy suppliers featured on their website). This leads me nicely onto the next place I recommend you get a quote..

2) Bulb.co.uk

Bulb is a 100% renewable, 10% green gas energy supplier that can supply energy to customers that have gas & electric, electric only, a smart meter or and a pre-payment meter. Every year, the average Bulb member saves 1.3 tonnes of CO2 from entering the atmosphere. That’s the same as planting 655 trees. They are rated 9.5/10 on TrustPilot with over 10,000 reviews, have a UK based support team and were the uSwitch Best Value for Money Winner 2018. They even pay your exit fees of your current supplier if you have any. They also have a referral program where both you and every friend you refer will benefit from £50. So you win, your friends win and the planet wins.

3) PurePlanet

PurePlanet is cool as it is Britain’s first app only renewable energy supplier, where you have a cute little PurePlanet app in your phone that has everything on it that you could possibly need. Yes – that means you no longer have to spend hours on the phone talking to your energy supplier.

Step 3: Decide which energy supplier you would like to go with

Once you have details of the cheapest suppliers to hand, you will be in a position to decide which energy supplier you would like to go with for the foreseeable future.

Remember that the lower the cost the better, but also bare in mind that to be as eco-friendly as possible it would be wise to swap to a renewable energy supplier (which may also happen to be the cheapest) so that you can do your bit to help the planet whilst also helping you to feel less guilty about the energy that you do use.

Step 4) Inform the energy you would like to swap to that you would like to swap to them

This is exciting, as after you do this step, all you need to do is wait patiently for your energy supply to be changed on your behalf by your new supplier. You can either swap online or call them up, although in most cases it is easier to swap online.

The number of days it takes to swap to your new supplier may vary slightly, but it is likely to be around 17 – 22 days from when you inform your new supplier that you want them to supply you with energy. They will likely confirm the swap date and keep you updated via email on any extra information they will need from you.

Information they may need can include a meter reading on the day you transfer, so that they won’t charge you for energy you’ve used before the switch (and they’ll inform your old supplier of this meter reading so they can send you a final bill or a refund if you are in credit. Your new supplier will also ask you to let them know your ‘MPRN’ or ‘MPAN’ numbers (which can be found on your energy bill that identify the meter supplying your home) as this helps them to make sure they switch your energy supply and not someone else’s.

Then you just have to sit back and relax and enjoy being on a cheaper (and hopefully renewable) energy tariff. Simples.

I hope you have found this guide useful. I would appreciate your honest feedback in the comments below. It would be cool if you can let me know if this guide has helped you to swap to a cheaper and renewable energy supply.

As always this is a guide only and it should not be relied upon when making decisions. You should always do your own research so that you can make an informed decision.
