How much have you cut you gas consumption by?

1961Nick

I would guess that since the price of domestic gas rose to 10.2p/kWh many of us will have reduced our consumption. How successful have you been during Oct/Nov/Dec compared with 2021?

2021 - 7273kWh
2022 - 3889kWh (-46%)

14% Electric and 16% gas but wasn't using much anyway

26% reduction on gas.  I made a number of changes in the last year including; 

1. underfloor insulation and internal Kingspan to the kitchen (which is the largest room in the house. 
2. New insulated garage door. 
3. Blocking up windows to the integral garage and insulating exterior walls. (The garage has around 60ft of central heating piping running through it so even though these were lagged a lot of heat was being lost from the draughts taking heat out of the pipes and the internal walls). 

The mild winter (so far) and putting up with colder temperatures have made a difference too.

I'm afraid zero! We had it terminated two years ago.

Similar. 
I suppose I have saved 10000kwh, as switched to electric only

I think it's the wrong question to ask. Because there are so many variables which change gas consumption from year to year a better question would be "what have you done to minimise your gas consumption?".

I checked my figures back to 2013 to see what the variance was & it's within the range 7273-9981kWh which is pretty tight.

I think I managed to drop about 4% last year and the year before. I haven't done the calculations for the full year, this year yet, but suspect it will be less than 4%, based on the numbers at the beginning of December. I feel like I may now be on dimishing returns. Which is a bit annoying as I'm no where near as low as I'd like to be.

Projected to reduce annual consumption of gas by a minimum of 45% or 9000 kWh, (22K kWh -> 13K kWh), assuming Jan and Feb '23 average temperatures are similar to December '22. More if milder. 

We use gas to heat the home, hot water and food.

Messy numbers here, due to A2A installs, Wifey working from home, and moving to all BEV household.

So, going back a few years, with PV, leccy consumption was around 3,500kWh (import ~2,000kWh), and gas was about 8,000kWh. Gas dropped to about 7,000kWh with the first A2A. This year dropped to 5,300kWh with a second and more useable placed A2A. Leccy has risen to 6,700kWh (import ~4,000). [Guesstimate of 2,500kWh for BEV's].

So gas + leccy was ~11,500kWh (3yrs ago), now ~12,000kWh but also including cars.

Gas:

511 m3 which roughly equates to 5,650kWh. Down from around 8,000kWh last year.

The big difference was a year of David Lloyd membership. Poor from a money saving point of view but saving 1,300kWh on water heating was a slight benefit. We're running the heating at 16.5 degrees now and have turned off the advanced heating algorithm so it doesn't preheat the house to temperature. The saving will add up to more this year as the colder winter months are usually Jan-March but it's dependent on the weather.

Electricity:

For the first time I have detailed data by combining the output from the Octopus and Myenergi APIs. 



A nice round 5,500kWh total usage with ~ 3,000kWh going to the car and 2,500kWh for the house. Just under 4,000kWh from the grid (split roughly 3:1 off-peak:peak); 1,550kWh came from solar (with 2,250kWh exported out of 3,800kWh generated).

Points to note: around 40kWh of peak import was specific to the savings sessions which cost ~ £10 but 'earned' about £70.

I actually stopped trying to use so much of the solar (despite having deemed exports) because the 5p Octopus Go rate made it cheaper to load shift where less than 80% of the power was coming from solar. The goal is to minimise peak imports rather than maximise self consumption.
