*New windows from Coral could save our customers hundreds of pounds on their heating bills*

You can check both your potential savings on heating costs and your CO2 savings by entering a few simple details into our energy calculator which can be found on our website https://www.coralwindows.co.uk

As an example, a typical customer (living in a semi-detached house which has wooden single glazed windows and mains gas heating) could save approx. £911 on their heating bill over the course of the first 12 months after they had new double-glazed windows installed by Coral Windows (information correct as at 13/10/2023).  Potential savings will vary depending on the information entered into the energy calculator.
