We help you make your home CHEAPER to heat, GREENER and BETTER to live in.

What do we offer?

We help homeowners and landlords improve the energy efficiency of their properties through expert assessment, advice and action.

Why act now?

To reduce your bills or greenhouse emissions.

To make your home warmer in the winter and fresher on hot summer days.

To improve the Energy Performance Certificate (EPC) score of your property.

What’s our approach?

The best choices are not always clear.

The Net Zero House team can help you understand and make good choices between different technologies; their installation costs, disruption level, running costs, carbon emissions and their impact on your Energy Performance Certificate (EPC) rating.

We also install insulation in lofts, walls and floors, improve draught-proofing and offer upgrades to ventilation systems.

We currently operate across Brighton and Hove and Sussex.

    Peter, Lewes

  • "Rob did a great job on our loft and was the ideal worker in courtesy and consideration; absolutely minimal disturbance and no mess, and he left the house immaculate. He is knowledgeable in his field, so I am confident that his work will result in a far cosier winter."

    Nick, Uckfield

  • "Our home has very tricky eaves space... they did a great job making a really neat installation and boarding out areas for storage, leaving the place clean and tidy. Rob is very knowledgeable and obviously cares about what he does… so I'm very happy to recommend him."

In the beginning…

“I started The Net Zero House in 2023 to help make homes greener and cheaper to heat.

Understanding what the options are, how they interact and what steps to take in what order can be daunting.

The aim of The Net Zero House is to offer straightforward, affordable services to help homeowners make their homes cosier, greener and cheaper to heat.”
