Hi,

I'm going a bit mad, for some reason my electric seems shockingly high, and gas shockingly low.

I'm with e.on and my rates are:
Electric £20.7p per unit
Gas 3.6p per unit

Today I took a meter reading. I have gas on and it's warm, and for electric, I've had just a few lights on, my PC, laptop. Nothing else, nothing big.

I apologise in advance for my shocking maths. I would really like some help to check my calcs are correct, if not, where I went wrong.
The average household uses per day:
Electricity: 8.5 – 10 kWh (8.5 to 10 units)
If my calcs are correct (please check), I'm on: 8.8 (units) per day
Gas – 33 – 38 kWh (33 to 38 units)
If my calcs are correct (please check), I'm on: 4 (units) per day
-----
Gas meter reading:
Today 12:36am
19129 (232)
Today 8:37pm
19131 (336)
8 hours between.

So that's 2 units per 8 hours, or
1 unit per 4 hour usage
As I work from home, I'll need approx 16 hours per day heating.
So that's 4 units needed per day.

My current tariff is
3.6p per unit, so:
3.6p x 4 (units) = 14.4p per day
14.4p per day x 30 (month) = £4.50
----
£4.50 per month in gas
/////////////////////////
Electric meter reading:
Today 12am
24406 (1)
Today 9pm
24411 (2)
9 hours between.

So that's 5 units per 9 hours, or
0.55 units per 1 hour usage
As I work from home, I'll need approx 16 hours per day electric.
So that's 8.8 units needed per day.

My current tariff is
20.7p per unit, so:
20.7p x 8.8 (units) = £1.82 per day
£1.82 per day x 30(month) = £54.6
----
£54.6 per month in electric

Tandy is correct. It may also be cubic ft, 1 unit would be 32 kWh.

Also I would take a couple of days or even a week reading rather than 9 hours, the energy you use cooking, multiple TVs, boiling kettles etc could add up to more. You would get a better estimate of typical use.

Cheeky plug for Octopus Go (1₩₩% renewable electricity) tarrif, for EV charging. I've recently signed up from a friend (with a telsa) recommended.

Octopus Go
Off-peak unit rate (00:30-04:30): 5p/kWh
Peak-rate unit rate: 14.29p/kWh
Daily standing charge: 25p

Annual electricty costs using Octopus Go:

Assuming all car charging performed using off-peak rate: 0.05 x 2,331 = £116.55
+
Household electricty usage: 0.1429 * 3200 = £457.28
+
Standing charge: 0.25 * 365 = £91.25

Total = 116.55 + 457.28 + 91.25 = £665.08

I don't think gas meters measure in kwh. They measure in cubic metres which are about 11kwh.
Thanks. So does that make my workings out a lot different? If so, how do I calculate it?

I'm just going by the meter reading on the dial.
At least the electric one seems more straight forward.

It usually explains it on the back of your bill.

Or check their website.

Thanks. It really shows just how useful a home storage battery would be then if you could charge it up for 5p/kWh then use that during the day.

The gas doesn't seem as a big deal to address as obviously it's eventually being phased out in renewable effort, plus elec gives you more flexibility.

My smart gas meter is kWh , house may not need so much gas, it will loose heat constantly + door openings, once warm just needs topping up.

Mine measures in cubic metres, then shows the kWh equivalent. I find it best to video the display with a phone camera so I can take a close look later - sometimes it is easy to misread the 7 segment displays depending on the angle you are looking from.
