What our customers say...
"We would like to express our satisfaction with the high standard of work and (relatively!) low level of disruption caused during the recent work carried out to completely replace our old central heating system. The new system is working admirably, and we would also add that we appreciated the professionalism and friendliness of the staff involved. We would be happy to recommend your firm to anyone requiring such work to be done."
Valerie and John Goode, St. Albans.

"Dear Les and All at Denver heating,
I wanted to say a BIG THANK YOU to you for fitting our boiler (last
September) it works away smoothly and quietly and I was impressed with the neat and swift job you did. We've saved money on Gas, although it's hard to tell exactly as we've been able to have the heating on more over the winter!
Will call upon you for a service later this year.
Thanks again,
Kind regards

We just want to say a huge thank you to Denver Heating. we would recommend them to anyone who was thinking of getting central heating installed."
