Retrofit, Solar & Home Energy Delivery Across the North East

    Coverage questions answered

    How do I check whether WHNZ covers my address?

    Submit a quote request with your postcode and the measure you are interested in. We check coverage for that measure in that area and tell you either way rather than leaving the enquiry open.

    Does WHNZ have offices across the North East?

    No. WHNZ is based in the North East and operates as a single business. Coverage across the region comes from the managed network of onboarded delivery specialists, not from branch offices.

    Can you deliver outside the North East?

    For some requirements, yes. It depends on the measure, the scale of the work and whether the network has genuine capability in that area. Programme and portfolio requirements are the most likely to be viable.

    Is availability the same for every measure?

    No. Coverage is measure specific, because specialists are onboarded and allocated by the measures they are competent and certified to deliver. A measure available in one area may not be available in another.
