Cost & Carbon

A ZEB costs £6,000 to purchase, which includes VAT and delivery. Currently, the ZEB isn’t zero-rated for VAT purposes (20% VAT applies). However from next year, eligible households will be able to access a £2,500 Boiler Upgrade Scheme grant to help reduce the cost of replacing a fossil fuel heating system. You can find out more about the grant and check your eligibility here.

Installation costs vary and depend on your home, heating system requirements and local installer rates – however as it should take no more than 1-2 days and you won’t need to change radiators the costs are lower than most alternatives. We can put you in touch with a tepeoPRO installer in your area to get a quote specific to your home.

Electricity is much cleaner than gas but is still generated from a range of sources, such as wind, solar, nuclear, and gas power stations. You can see how clean the UK’s electricity is in the widget on the left.

As more renewable sources (wind, solar etc.) become available to generate electricity, it will become much cleaner. Flexible energy storage technologies like the ZEB help to speed up the transition to a renewable grid, by storing excess renewable generation when it’s available and avoiding using electricity at peak times which tend to have a higher carbon intensity.
