NetZero Careers

Accounts Assistant

Through forward thinking, innovative technology and energy efficient, off-site manufactured buildings, we are transforming the speed, cost and environmental impact of new buildings.

We create award winning energy efficient, modern purpose-built net zero carbon buildings mainly focused in the education sector but with plans to expand our business activity into the residential and primary health markets.

We are a market leader in sustainable buildings and have become a prominent voice in the transition to the net zero building. We are committed to continually developing new buildings that meet the needs of our customers through being high quality, delivered faster with a lower cost than through traditional construction methods, whilst being kinder to the environment. Our buildings typically feature airtight, thermally efficient envelopes, heat recovery ventilation, integrated solar roofs and smart controls. They are designed to generate more power than they use. This approach significantly reduces ongoing energy bills for our customers and eliminates the carbon emissions associated with producing the energy that less intelligent buildings consume to operate.

Since 2012 we have designed and built over 75 schemes throughout the UK with an average EPC rating of A+ across our projects. We believe NetZero has delivered the highest number of A+ EPC rated school buildings in the UK. NetZero has won many awards over the last 4 years including Greenbuild Awards, Building Technology of the Year, Public Building Energy Project of the Year, Public Sector Energy Champion for Schools, School Building of the Year and most recently the Department for Education’s Environmental Award

Our business is rapidly growing and we are putting in place a team who have the skills, experience and determination to successfully deliver our record breaking pipeline.
