greentomatoenergy provides advice on how to make your build more energy efficient
It may not be glamourous, but at greentomatoenergy we believe in applying the laws of physics to low energy building. In order to mitigate against the risks of low energy building (primarily performance, cost and fabric), our team of engineers will apply real science to your project. This will give you the confidence that the work you are doing will deliver lasting results.
We are an independent consultancy that will propose the most appropriate solutions, helping you to avoid the minefield of technology-specific salespeople.
Our services
We provide three types of consultancy:
- Full Energy Design
- Energy Survey
- Bespoke Energy Advice
We work with builders, architects, designers and self-builders to ensure that the most practical, affordable and efficient renewable and energy-saving measures are selected for each project. We will provide support through each step of the build process.
