Our pandemic response

For issues with your heating and/or hot water or any leaks from the system then please call our helpdesk on the number above. During your call our team may now take some additional information from you so that your individual circumstances can be assessed and we can take the most appropriate course of action. Please be mindful that due to the necessary protective measures for both you and our engineers, our service levels may differ from normal arrangements.
All non-essential visits into domestic properties will be subject to the latest COVID-19 government guidance. Non-essential visits include meter inspections and high/low usage inspections. If you require further information, please get in touch with us.
We appreciate that the current situation may result in financial hardship for some of our customers. If you have any such concerns, you should get in touch with us via email leaving a phone number so that we can call you back.
