How much can you save by going all-electric in New Zealand?

Across the New Zealand households using Cogo, the average home could save around $3,000 a year off its power bill by making the electric upgrades they are already considering. That figure is the house alone, and does not include anything you would save on petrol by switching the car. Here is where the saving actually comes from, what to do first, and why it does not have to happen all at once.

Hot water is about a third of your power bill. Here's how to cut it.

Hot water is about 30% of the average New Zealand household's energy use, which makes it the biggest chunk of most power bills, yet it's often not thought about. Here's four ways to cut costs, starting with the cheapest: change when the cylinder heats, insulate the cylinder and its pipes, replace it with a hot water heat pump, or divert your own solar into it. One thing you shouldn't do is turn down the cylinder temperature.

Do you need a battery to make solar worth it in New Zealand?

Do you actually need a battery to make solar pay? Not necessarily. Panels earn their keep on the power you use while the sun is up, so if someone is home in the daytime, or the hot water and the appliances can be shifted into the middle of it, panels alone stack up. A battery is a second, separate decision, and it is really about your evenings. We run the numbers on both, using MBIE's model household, and set out which one fits which house.

Is a second-hand EV worth it in NZ in 2026?

Petrol prices this winter are climbing towards $3.50 a litre, and thousands of Kiwi households have responded by going electric. But do the numbers still stack up now that EVs pay road user charges? We ran the honest maths: charging at home works out at the equivalent of about $1.60 a litre with RUC included, worth roughly $1,150 to $1,800 a year for a typical household. And you don't need a new car to get those savings. Each one of the 10 EVs most saved by Cogo users is second-hand, with the used BYD Atto 3 leading the pack.

How the Warm Homes Plan puts banks back at the centre of the home energy transition

For climate and lending teams, the Warm Homes Plan represents the market intervention we've been waiting for. Government-backed low-interest loans finally make retrofit financially viable for the millions of so called "able-to-pay" homeowners who've sat on the sidelines. The banks that crack the customer journey now will own this market as it scales beyond initial subsidies into a self-sustaining opportunity.

Join Cogo’s Retrofit Platform Pilot: Solving the challenge of home energy retrofits

Home energy retrofits are essential to the UK’s net zero journey, but progress remains slow. The solutions exist - from insulation to electrification - yet homeowners face financial and practical barriers to action. Through Cogo’s Retrofit Platform Pilot, we’re inviting banks and building societies to explore how partnership, innovation, and green finance can accelerate adoption. This is a unique opportunity to co-create new models that help households act - and position lenders at the heart of the home energy transition.

How banks can accelerate the home energy transition through green mortgages

Residential buildings are responsible for nearly a fifth of global emissions. Decarbonising housing is therefore one of the biggest climate challenges we face. The technologies to cut household emissions already exist, from heat pumps and solar panels to insulation and energy-efficient appliances. The real challenge lies in enabling households to overcome the financial and practical barriers to adoption. This is where banks have a unique opportunity to step in.
