Great comparison site, saved me a ton of time and effort and money. Would definitely use again for sure.
Mark S
Very pleased with our installer that we matched with through energiser.ai who was very professional and always on time.
Kate M
We installed solar panels 10 years ago and had trouble finding a reliable installer. This time around with energiser.ai it was so much easier. Thanks
Jim B
We got more and better quotes in 1 minute using energiser.ai than we did with 3 weeks of calling around ourselves. Very impressed.
Harry W
I was going to use one of the big energy companies but ended up saving £6,000 off the solar panels with a contractor I found on energiser.ai
Joan S
The renewables solution I got from energiser.ai was more accurate than the ones I got from two installers coming round to my home.
Matthew R
I have used energiser.ai for solar and then again for a heat pump over a period of a few months and each time I have saved a lot of money and grey hairs!
Chris L
Never seen a renewables comparison site before so was a bit sceptical, but can honestly say it made the process so much easier and simpler for me.
