About us
22 years of other people's emergencies.
Carr Denzy started as one van and a mobile number. It is now a small team of Gas Safe registered engineers and builders working across Nottingham, and the way we work has not really changed: turn up when we said, explain what we found, and charge what we quoted.

Credentials
- Gas Safe registered
- Accredited installers of Worcester and Bosch
- REFCOM registered
- Public liability insured to £5m
How we work
Diagnose before quoting
A boiler that has locked out is not automatically a boiler that needs replacing. We find out what is actually wrong first, and tell you if the cheaper answer is the right one.
Written prices, line by line
Labour and parts listed separately, so you can see what you are paying for. The quoted figure is the figure, unless something turns up behind a wall that nobody could have known about — and you hear about that before we carry on.
We finish what we opened
If we cut into a wall or lifted a floor to reach a pipe, we put it back. You should not have to find a plasterer to complete our job.
The record stays yours
Every photograph, note, quote and invoice stays in your account. When you sell the house or a new tenant asks, the history is there.
Where we work
Nottingham, Nottinghamshire, Derbyshire, Leicestershire. If you are just outside that, ring and ask — we will tell you honestly whether it is worth our travelling.
Opening hours
- Monday to Saturday
- 9:00am – 5:00pm
- Sunday
- Closed — enquiries answered Monday
Emergency call-outs run outside those hours Monday to Saturday. We do not attend on Sundays — if you send the form we will pick it up first thing Monday.
Insurance
Public liability cover to £5m, and every gas engineer on the team carries a current Gas Safe ID card. Ask to see it at the door — a genuine engineer will expect you to.
