Climate Leaders’ Electrifying Revamp, St Andrews Road, Cambridge

Meet your hosts, Chris and Linda 

We moved into the house in 2015, when our kids were secondary school age, but are now empty nesters. A professional couple working in tech and academic research, we consider global heating to be exactly what the scientists call it – an emergency. When there’s an emergency you change how you do things and what you prioritise.  

So, when our old gas boiler sprang a leak that didn’t end its life immediately but would have led to its demise within a year, we decided to come off gas. An air-source heat pump was the only alternative option for us. 

Chris says “the aim was to electrify everything, reduce our carbon footprint, and generate as much of our own energy as we could. We did a lot of research and found the Cambridge Transition Energy Group to be a great resource for information and advice.” 

We didn’t undertake the works to save money, nor did we calculate the payback periods. We saw these improvements in our home and lifestyle as an investment in a sustainable future. Our aim was to electrify everything and generate as much as we can. We are nearly off gas but are holding off installing the induction hob for now. We’re thrilled that we are very nearly at our goal and quite happy to stop thinking about energy improvements!

Our hosts’ top tips  

  • Sort out the insulation and windows first if they need it 
  • Visit people with ASHP or solar to learn about it. Don’t believe everything you read, particularly from some quarters of the media. 
  • Don’t feel you have to do *everything* and get to ultra-efficient. Every improvement is a good step forward.
