Comparable pricing for all our customers
Our charges are set to be comparable with the cost of generating heat from an individual boiler, which includes the cost of gas, as well as the costs of running, maintaining and replacing a boiler.
Each year, SDEN may conduct an annual price review, which is made in agreement with the developer of your property, Barratt David Wilson Homes/Barratt London.
Details of our pricing policy can be viewed here.
