Forget paltry 5% gas price cuts announced by the big six firms - if you're one of the 70% on a standard tariff, you're still being screwed.

Yet our 4th MSE collective switch (not in NI, sadly) can save a typical £345/yr, but the clock's ticking as it ends late tomorrow night (Thu), though the headline deal may go sooner. It only takes 5 mins, then you're switched in 17 days.

In the fortnight since we launched our collective we've broken all records and 97,000+ have already switched. Linzi tweeted: "Thanks for keeping on at us. I've switched and I'm saving £77/month, £924/year." Holidayangel tweeted: "Thanks. I've never switched & just saved a massive £645. Stayed with British Gas, easy."

A collective's where a trusted intermediary (eg, a council or us) runs an auction for energy firms to bid to provide special tariffs. Our huge 11m email recipients & 2m Cheap Energy Club members mean ours smash even the market's cheapest for most.

Are you eligible for Big Switch 4? Ofgem rules now mean we need to pre-register people for collective switches. You need to have been on the distribution list for our weekly email or our Cheap Energy Club before 1 Feb.

How do I check if I can get it? Use our Can I get the collective? checker. Or for speed go straight to the Cheap Energy Club comparison and if you can get the collective it'll be in your results, if the tariffs are still available. Sorry, over the past fortnight huge numbers meant pages were slow - the team's working tirelessly to keep it working, please be patient.

What if I'm not eligible? You can still save large (just not quite as much) - there's no point waiting, every day of overpaying costs. Many can still save £100s, so use our Top Picks Comparison to see what you can get.

I'm eligible - can I change my email? First use the registered email, but when actually switching, on the form you can give a new one (if you want, you can return after switching & change your registered email with Cheap Energy Club too).

Cheapest dual fuel - GO QUICK. Special British Gas dual fuel tariff - 30,000 left. It's not often the UK's largest supplier competes on price, but this MSE British Gas 12-month tariff saves someone with typical bills on a big six standard tariff £345/yr. And EXISTING British Gas customers can get it (as can Sainsbury's Energy customers).

This was originally capped by BG at 100k switches to prevent it being swamped but we asked it to extend the cap, and as it says it's coping, it's agreed to 125k. While 30k seems a lot left there's a chance they'll go before Thu night. To get the tariff you need to do a comparison, and if you're eligible and it's still available it'll be in your results. If not, you'll see the next best which should still save you a typical £300+/yr.

Key facts...

- You also get £30 dual fuel cashback from Cheap Energy Club.
- It's available for dual fuel (gas & elec together), incl Eco 7.
- You must opt to pay by monthly direct debit.
- Leave early and there's a £30 exit fee per fuel.
- As it's a fix, the rate (not cost, that depends on use) is fixed for 1yr.
- If you move home you can take it with you.
- Existing BG & Sainsbury's Energy custs can switch to it with no exit fee regardless of their tariff, and get the £30 cashback.

Cheapest GREEN tariff. Bulb 100% renewable tariff plus £12.50/fuel J Lewis vch. This is for those who want to do their bit for the environment and still save massively over standard tariffs.

This was originally capped at 1,000 tariffs but Bulb removed the limit last week.

- You get £30 dual fuel cashback from Cheap Energy Club.

- Good for you if: 1) You want a competitive price but will pay a little more for green. 2) You're happy to switch again in a year.

- Not for you if: 1) You just want the cheapest price. 2) You want to be able to switch penalty-free (though the penalty is small). 3) You're with an independent gas transporter (IGT), as Bulb charges an extra £8.33/mth (£100/yr).

- How's customer service? Bulb is a small, new supplier, so we've no feedback on its service - however we have visited it, checked it can handle the traffic and set up boosted customer service for our switch. Hopefully all good.

Cheapest ELECTRICITY-ONLY tariff. E.on 12mth fix. Our winner is the MSE E.on 12mth fix, but we need to be straight as it won't always win. It's best at mid to low use, especially when you factor in our cashback. Click the link and you'll get a comparison showing you - if it doesn't win, you'll likely be shown you still save elsewhere.

- Existing E.on customers can get it without paying an exit fee regardless of what elec tariff they're on, even if part of a dual fuel deal.
- You also get £15 switching cashback from Cheap Energy Club.
- Tick 'sign up to E.on points' during sign up & over 12mths you'll get 1,500 pts, convertible into 1,500 Tesco Clubcard pts or a £15 high st vch (incl Argos).
- It works on Economy 7.
- You can opt to pay by monthly direct debit or costlier quarterly cash / cheque / direct debit.
- Leave early and there's a £30 exit fee.
- As it's a fix, the rate (not cost, that depends on use) is fixed for 1yr.

How it compares
Roughly based on the ELEC-ONLY usage of someone with oil/other heating

Typical cost: Current big six standard tariff: £505/yr
MSE Special: E.on 12mth fix: £380/yr + £15 cashback, £30 exit fee
Next cheapest open market 12mth fix: GB Energy: £379/yr - no cashback, no exit fee

- Good for you if: 1) You don't have gas. 2) You are happy to switch again in a year. 3) You shop at Tesco and collect Clubcard points.

- Not for you if: 1) You're an electricity-only user but have high usage - but then still click the link to do a full comparison. 2) You want to be able to switch penalty-free within the year.

- How's customer service? In our last customer service poll E.on did well, scoring 58% 'great' and 11% 'poor' from 688 votes. We've worked with E.on in our previous Big Switch Events, have boosted customer service resources for it, and found it good at dealing with issues.

Cheapest prepaid - SADLY no winner. We tried for a key or card tariff, but no supplier beat the market's best buys, so we wouldn't put our name to it. Yet use our Prepay Comparison to find your cheapest - many can save £110/year.

However, even on them you'll still be paying £300/yr more than the cheapest direct debit deal. See Can I switch to a standard meter?

The MSE Big Switch Event 4 FAQs
For more detailed answers see the full MSE collective FAQs


Q. I'm already with one of these providers (eg, BG). Can I still switch? Yes, plus you won't have to pay any exit fees & you still get our cashback.

Q. Will the collective tariffs always win? Mostly, not always. It depends where you live and your usage, which is why we do this via a comparison.

Q. My fix ends soon (incl MSE's Big Switch Event 2), can I do this? Yes, within 49 days of it ending your supplier CAN'T charge exit fees.

Q. How does Cheap Energy Club work? When you join, 3 things happen:

1) We show your exact price, saving & compare to ALL market tariffs. While our collective tariffs usually win, there can be regional & usage variations.
2) You get £30 dual fuel cashback (£15 elec-only). Any time we can switch you (collective switch or not) we give this, sent roughly 60-90 days later.
3) We monitor that it stays cheap. You set a 'trigger saving', eg, £150/yr, then we alert you if you can save this by switching again - perfect for fixes where cheap rates go quick. This takes the hassle out of energy tarting, where you constantly switch to get the cheapest rate.

Q. What do I need to switch? A bill - preferably your annual bill - would be good, and use kWh rather than cost if you can. But if you don't have that, estimate your usage (if you're moving home the comparison does it for you) and while the answer won't be perfect, it shouldn't be far out.

Q. Does MSE make money from this? Yes. We're paid £60ish/dual fuel switch & give you £30 as cashback. After supplier costs we get £11 for costs & profit.

Q. I'm locked into a fix - should I switch? Possibly. Do our comparison, which shows how much you'd save compared with your current fix & the price it jumps to after. Just ensure you factor in exit fees.

Q. Who's responsible for these tariffs - MSE or the energy firm? The energy firm is, and you pay it. But we take our bit seriously and ask all providers to set up special customer help teams with max 48-hour response times. If something goes wrong, and it won't help, let us know and we'll try to help.

Q. If prices are dropping, should I wait? Standard price cuts are trivial compared with the savings possible here. If other cheap deals launch during our collective, they'll be shown in your comparison. Prices may continue to fall after, but switching now means saving now. Drops would need be huge to overcome that, and if they are, save now and pay the exit fees to switch then.

More quick FAQs:

Q. I'm in credit - will I get it back if I switch? Yes. See Reclaim credit.
Q. I'm in debt - can I switch? Yes, usually - see switching in debt help.
Q. Can I see the standing charge and kWh costs? They vary by region, so we display YOUR exact cost in the Cheap Energy Club comparison result.
Q. Can I switch if I've solar & FIT? Yes. See full solar & FIT info.
Q. On a smart meter? Can I switch? Yes, but you may lose functionality.
Q. Do I keep my Warm Home Discount? It depends, see Warm Home info.
Q. Is there a credit check? BG and E.on yes (unless you're an existing customer), Green Star and Bulb no. See collective credit check info.
Q. Can I get paper bills? Yes (not Bulb) but you'll pay up to £15/yr more - see paper bills.
Q. Can I switch if with an independent gas transporter? Yes, see IGT help.
Q. Is paying by direct debit cheapest? Yes, but do regular meter readings.
Q. Can they put my price up on a cheap fix? The rate's fixed, but use more (or if it's estimated you will) & the direct debit can rise. See Fight Unfair Direct Debits.
Q. Can I switch if I'm renting? Yes. See our Renters' Factsheet.
