Fantastic news. The UK is making real progress here, and hopefully this will be good news for prices and for energy security in the future.
We're already at 70%+ of our energy coming from non-fossil-fuel sources, much higher than I expected: https://grid.iamkate.com/

Just to be picky… electricity…
We've still got a lot to do to decarbonise the rest of our energy usage EVs, heat pumps, improving housing stock, electric trains etc

I think a lot of that comes down to cost.
If we can drop the price of electricity enough it will naturally become the favoured choice for heating and transportation too.

imho, not picky at all - in fact, a critical distinction, as the transportation slice of the energy pie is really quite a large one.

Reducing the transportation slice of the pie is a double win as something 50% of marine transport is shipping hydrocarbons around the world

My gas usage in KWh vastly outweighs my electricity usage.

It's not apples-to-apples though due to the difference in heating efficiency. If you use N kWh to heat your house with a gas boiler, you'll use N/P to heat it with a heat pump. P is something like 3 or 4, depending on various factors (and who you ask).

Potentially bigger. There are a lot of old non-condenser boilers out there, with a typical efficiency of about 70%. And even condensers are often not much better than 75-80%; to hit the faceplate 90%+ efficiencies the system needs to be balanced such that the return temperature is in quite a narrow range.

I don't see many heat pumps in the wild - I do see plenty of resistive heaters and electric "power showers" still.

As long as they're powered by "clean" electricity it doesn't really matter though.

Depends on the context; if you are presently using x kWh of electricity for non-heating plus 2x kWh of gas for heating, your options for electrical heating are either to 3x your electricity demand by "upgrading" to resistive, or 1.5x (or whatever) your demand by upgrading to a heatpump.
There's other stuff you can also do, but costs are all over the place, e.g. my 110 ish sqm house in Berlin is so well insulated (and has heat pump) that even while it's snowing outside it's hot enough indoors to be naked, for an electricity bill that's lower than that of my 37 square meter apartment in the UK, despite German electricity prices being much higher.

Yep, just checked and my gas is just under double my electricity for 2025.
9,000kWh for electricity vs 16,000kWh for gas
That’s with charging an EV too.

And construction as well. Concrete is emission-y.

Usually calculated to be a 15-25% grid increase. Not massive compared to decarbonizing industries relying directly on fossil feedstock/energy.

Heating from gas is quite peaky (morning and evening heating cycles), whereas heat pumps are best when run low-and-steady.
Assuming 2/3 of residential heat demand transitions to heat pumps, and assuming an optimistic COP of 3 in the worst weather (highest flow temperatures, lowest air temperatures ... perhaps more like 2.5), then the power required to heat this fraction of houses is 2/3 / 3 = 2/9 of the mean gas demand. [0] linked report figure 1 shows a (smoothed by eyeball) demand of around 140GW "local gas demand" during the Beast from the East. This implies heat pumps would take over 31GW to power, which is more like 60% of the current UK electricity supply.

Not sure why you’re talking about heating when the parent, and my comment address transportation?

Sorry, alignment issue! Probably transport is less troublesome as it has a decent element of demand side response to it (batteries sufficiently large for a couple of days without charging).

Is it actually the case on an annualised basis? Or was it just the case when you looked at the live grid data? (There is also the issue with "biomass", which is wood imported from abroad to be burnt)

Yes -- you can switch to see the past year's data. Fossil fuels are at about 29%!

Ah yes, I can see it now: 28.9% for fossil fuels over the past year.
