Sustainability and energy performance are a crucial part of every building project. It’s something we all want to get right, but the targets and the rules keep changing…


….luckily, you don’t have to tackle it alone.

Buildpass is your one-stop energy and sustainability consultant

We are Buildpass and we’re here to help you conquer the world of energy performance and sustainability. We’ll help you get it right and navigate the complexities. You’ll meet planning and building control requirements, reduce your risks, cut your costs and tick all the boxes.

You’ll be able to focus on what you do best because you’ll know compliance, testing and certification are all taken care of.

But ticking boxes is just the start. Whether you’re an architect, developer, contractor or homeowner, we can help you:

  • integrate energy efficiency into the initial design, saving you time and money later on.
  • push the limits of what’s possible and reap the rewards of a building that costs next-to-nothing to run.
  • turn a potential minefield into a simple, streamlined and enjoyable process.
  • contribute to the increasingly urgent movement to combat climate change.

From our base in Southampton, we work across the south of England, London and the home counties – and we also have clients in the further corners of the UK.

Do give us a call or send us an email, and let’s start talking.


But who are we?

I’m Andrew, and I am the Director here at Buildpass. I’m something of a geek when it comes to sustainability and energy performance. Ever since I started out, I’ve been hooked on the intricacies of energy performance and the vagaries of our government’s policies. I know it’s not everyone’s cup of tea, but it’s most certainly mine. And on this warming planet of ours, it’s becoming more and more important.
