You can model building thermodynamics on paper all day, but nothing tests a home's efficiency quite like an unexpected system failure in late autumn.å

When a faulty control board brought our heat pump to a complete halt on the 29th October, we faced a full week without heating.

Spoiler alert - we did not freeze. Instead, we got a firsthand look at how our insulation, triple glazing, and thermal mass perform under pressure.

And discovered a few simple adjustments that kept the house surprisingly warm, that we'll keep going forward!

Making it count, your EPC that is!

Energy performance certificates were launched in the UK in 2007, initially to help people assess homes they were thinking of buying. But they soon became a useful metric for ensuring new building were meeting building regulations.

Our current home had one for this reason - as it was built in 2010 - at least to the point where it could be assessed.

It's had two assessments since then, and somewhere between the three reports the true picture of our house's performance can be seen.

Why do I say that? Listen to this episode and find out how you can use the EPC to improve your home's energy usage.

After all, it's meant to be child's play!

Remember, the recommendations in the EPC do not have to be done all in one go to give you benefit. Insulation teamed with great heating controls have a multiplier effect more than the sum of their parts.

At the end of the episode is a teaser for next week looking at other steps to reducing your energy usage while boosting your nutrition.

And we're not scared.

We're not talking about the blood suckers like Dracula, secretly taking blood from Lucy Westenra.

We're talking about the hidden draws of electricity lurking in your home. How can you make use of your telemetry to make the most out of tracking these down?

Is it worth the effort? I give an example of our outside lights, which were only taking 30W while they were on. Leaving them on while we had the flu for 7 days meant we wasted 5kWh or £1.34.

That may not seem like much but that is running the microwave on full pelt for 5 hours - what could you do with that energy? What tasty treats for the trick or treaters could you rustle up?

See what garlic we used to defeat this leeching draw of power. And the steps we took elsewhere to stop these pests.

Our journey surmised in 27 minutes.

In 2013, we bought our house, already upgrading from an EPC D to C.

This episode takes you through that trek: it wasn't a jump all taken in one fast paced transformation but one considered step after another.

What worked I tended to share on the Driving off the Grid blog. What didn't was chalked up to experience. And shared else where. Most steps were well taken.

Listen to the story here.

In today's episode, I look at how we've used home automation to reduce vampiric loads on our electricity and yet remove some of the friction in day-to-day life.

This is Heat Pump week, but using automation in terms of our heating schedule unlocked the savings available in our heat pump, and made life so much more comfortable.

Lighting automation can be contentious in a busy and flexible household, so what's the right mix for you? How can you make the most of that investment? Isn't it just easier to go and push the switch on the wall?

Find out how we made the steps towards our automated house. Is there anything you can share on living in the 21st Century?

Hi, it’s National Heat Pump Week, and while we are huge advocates for low-carbon heating, we know the elephant in the room: heat pumps aren't financially or physically accessible for everyone right now.

Yet with the high price of natural gas, how can you make your heating work for you?

For this special off-schedule episode of Driving Off the Grid, we wanted to tackle the question: what can you do if you're stuck on gas or oil and either renting or not ready for a big capital upgrade?

Before we ever installed our heat pump, we spent three years getting our home into shape. Focusing on smart controls, lowering boiler flow temperatures, and phasing upgrades room-by-room, we dropped our annual heating consumption from 17 MWh down to 12.8 MWh. A massive 30% reduction in energy demand without sitting in the cold. We did it in small steps, none costing more than a takeaway for four!

In this episode, we break down:

• 🌡️ The 55°C Boiler Trick: How a simple dial adjustment pushes your gas boiler into its high-efficiency condensing zone.

• 🎯 Smart Zoning on a Budget: Why room-by-room scheduling with smart TRVs beats heating empty space.

• 🎭 Low-Cost Fabric Wins: Easy insulation hacks (like thermal curtain linings and draught excluders) that anyone, including renters, can implement.

The high price of natural gas means it is not enough just to turn down the boiler, you need to get it working better for you. Share your tips on how to make the most of your heat here.

Today's hot episode is all about the heat.

As the first cold day is approaching, how can you get the most out of any planned heat pump or one you have in place?

Why does the planning of the installation matter? Why should you look at the settings?

Heat pumps are not the only story in town when it comes to electric heating but getting it right can make it pay for itself.

On Saturday the numbers behind this podcast will be published on Driving off the Grid - heat pump section.

What happens when you drive an early-generation electric vehicle for over a decade, rack up thousands of miles, and bypass modern tech nannies entirely?

In this episode, we’re cutting through the second-hand EV panic and looking at the reality of long-term electric ownership. From keeping maintenance bills under £200 per annum and proving that replacing early battery packs is not a massive cost when the time comes, to why we should celebrate "dumb" cars that don't aggressively yank your steering wheel on country lanes, this episode is about the real-world economics of keeping a classic EV on the road.

Forget the hype, the anxiety, and the endless alerts. Let’s talk about true automotive longevity and driving joy. See why I 💚 our Leaf.
