Price cap increases- To fix or not to fix?

Customers on variable tariffs (SVT) are being notified these days of tariff increases from 1 January. At the same time, many are being given the opportunity to switch to a fixed-rate tariff. I am trying to decide whether it would be a good idea to fix, but I’m not sure I have all the information I need. Gas hasn’t been invented yet in my corner of the world, so I’m only interested in electricity tariffs.

Cornwall Insight are a well respected crystal-ball gazer where energy prices are concerned. Their predictions for 2024 show small ups and downs in unit prices, but one startling forecast is for a hike in the standing charge of the order of 15% on 1 April. For a light user like me, this is hugely significant. On SVT, the standing charge would amount to 37% of my bill in January, but by October this would have risen to more than 41%. The fixed rates I’m being offered would keep the standing charge at more or less the current level, so that makes fixing look like a good idea. 

But … we know that Ofgem are considering changes to the way standing charges are calculated and applied. If by some miracle any change were to be implemented before 1 October next, would I miss out on any benefit this might bring? I guess the answer to that is Yes, but that it’s not very likely any change will happen by then. Agree?

And does anyone know the reason for the increase in standing charges predicted for 1 April next? Are we going to be paying for the cost of bailing out Bulb customers?

The Energy Price Cap, set by Ofgem, is normally changed on 01/01, 01/04, 01/07 and 01/10 each year. The price cap can go up or down and, if you’re on the standard variable tariff (Simpler Energy) then your rates will go up or down to match the price cap change. We offer fixed tariffs for one or two years. If you opt in for a fixed tariff then your rates will be fixed, and protected from price cap changes. If you’re up for renewal, or are currently on the Simpler Energy plan, you can switch to a fixed tariff via your online account or app (see below).

 

 

I’ve been asked about the question ‘to fix or not to fix’ often in the last few months and I always offer the same answer .. how comfortable are you with the possibility that prices might increase over the next year?

There are no two ways about it .. it is a gamble. I liken it to taking out insurance (the optional sort) where it’s a calculation as to the possibility of an expense for a loss/damage compared to - for the most part - having financial cover for those things.

Back in 2021 we fixed our energy rate for 2 years and almost everybody told me that it was at too high a level. Little did I (or anybody else) know about the pending war in Ukraine and the problems with supply from the Russian pipeline.

This time, despite the outlook, we have not fixed .. although, in effect, our tariff is a constant variable if that makes any sense. All of that is why I’ve invested in solar PV, battery storage, a Ripple community solar park and a small wind generator, so that we have a degree of self/low generation support whatever happens

...but an 8p hike in the SC means a guaranteed annual cost increase of ~£20. I suggest you do your own sums!

0.08*365=£29.20

just saying….

It’s all theoretical to me, presumably due to being on a occult tariff

During the energy-price uncertainty, we’re not able to offer a fair priced fixed-rate plan. Our variable-rate Simpler Energy plan is the only one available at the moment. These prices are in line with Ofgem’s price cap.

The average electricity standing charge from 1st Jan is 53.35p

The average standing charge from 1st April according to the latest Cornwall estimate is 58p

58-53.35 = 4.65p a day if a consistent 58p

£16.97 for a year increase.

It wouldn't take much of a change following the standing charge consultation to overcome that sometime over the next 12 months.

The unit rate may be well be over 4p a unit less from 1st April based on current average estimates from Cornwall Insight. I assume even low energy users are using more than 1kWh a day

These are all averages, unit rates and standing charges vary by region

You trying to ruin Christmas for me? The new Cornwall prediction came out the day I fixed, so I’ve still got a few days to cool off in. Back to the drawing board.

For a start, Cornwall’s figures are heavily rounded, so we should really be comparing the earlier forecast - 60 or 61p - to the current 53, which is where the 8p increase I quoted arose. Second, do we know whether the threatened £16 bad payer levy is included in Cornwall’s assessments?

The forecast reduction in unit prices from the Q1 figures is quite dramatic - 28.62 to 24.09 to 22.56 - and would have a significant effect on bills as you point out. I know you’ve been expecting something of the sort, based on your scrutiny of forward wholesale prices. I’ll have to dig out the old slide rule and crunch the numbers again, but at first glance it would seem that SVT would trump a one-year fix based on my usage (~3kWh/day).

It is impossible to know for sure @Firedog 

The fix price gives piece of mind. That is not a bad thing. I am definitely not suggesting you should take a risk with the standard tariff 

We know the ofgem announcement on the £16 debt going on the unit rate rather than the standing charge was announced prior to the Cornwall Insight estimate.

The £16 debt and rounding is relatively small but not insignificant compared with the drop in wholesale prices currently for many people but not for low users.

Quite a lot could happen as a result of the standing charge review.

Of course a new government and ofgem could do something unexpected quickly. 

The main thing currently is what will happen to the wholesale price of gas between now and 15th Feb when the calculation period for the Q1 2024 period finishes. It has been volatile so Cornwall Insight may well be wrong particularly for Q2, Q3, Q4. This is the latest price.

You may simply decide to fix for piece of mind.

OK. I ran the numbers again with the latest CI predictions, with a bit of massaging. The rates in my part of the world tend to be about 95% of the national average, although the standing charge is probably a bit less than that. Anyway, using OVO’s SVT rates for Q1 and Cornwall’s predictions for Q2, Q3 and Q4, along with my own quarterly consumption figures for 2023 (including December 2022 instead of 2023), it looks as if the rates I fixed on would cost between £10 and £17 a year less than the SVT for the standing charge, but the fuel cost would be about £41 higher. I’m not happy with a fixed rate plan that could cost me £25-£30 more than the SVT and still saddle me with a £75 exit fee. 

I’ll be using your magic freephone number to cancel the fix later on in the week if webchat doesn’t work. Wish me luck!

Predictions are just predictions - AKA ‘best guesses’ - you have just seen that they change, and CI could be predicting something else next week. (And certainly will be by April)

You make a decision and you fix or don’t fix, that’s your own particular guess/gamble, and then you see how it pans out.

I made my decision to fix, based on current /Januarys SVT vs the Fixed Rates offered, and will now stand by that decision.
Personally I don’t see the point in wavering now just because someone else’s guesses have changed.

I said, Hey - Watts going on.

That’s a confusing page. But I eventually whittled it down to see there are only two economy 10 tariffs on DB, which are both identical. So that explains why there is nothing to change to. I am stuck unless I want to change to a single tariff (which SSE said I could do, but I haven’t asked Ovo). I won’t do this yet, until I make my final decision about heating.

I’m fairly sure that CI’s guesses are closer to the truth than anything I could ever come up with. In particular, I think that their Q2 forecast for unit rates is likely to be close to whatever Ofgem settle on in just a few weeks’ time. My rationale for fixing was based on estimates that have changed significantly, and the new figures indicate that what might have been to my benefit before is no longer so advantageous. It’s a fairly safe rule that the most recent prophecy is more likely to be right than earlier ones. 

The last time I fixed my rates, for two years, it was just before the price cap went into orbit in 2021. That saved me an awful lot. Let’s see how we go over the next year.
