The heat interface unit (HIU) is a box that looks like a boiler. It transfers the heat from the district heating network into your home, it makes heat available instantly, whenever it’s required for hot water or central heating.
It has been brought to our attention that some customers either may not be aware of, or are confused by the HIU Repair Period and HIU Inspection Period, including:
We have prepared this letter in response and to try and add further clarity for our customers.
HIU Repair Period means the period during which East London Energy are liable for the maintenance and repair of the HIU. Taken from Definitions of the Residential Supply Agreement
The HIU Repair Period is seven years from the date we accepted the block, phase, or development as appropriate of which your property is a part and started delivering operations, maintenance, metering, and billing services.
During the HIU Repair Period, we are responsible for any labour costs in association with any routine inspection, maintenance, repair and/or replacement of the HIU. An arrangement has been entered into with the developer of your property for the supply of parts and or replacement during this period.
On the eighth anniversary of the HIU Repair Period, the HIU will become part of your home’s heating system. This means the heating system inside your home including all pipes, radiators, hot water cylinders and other apparatus (but not including the meter, or the HIU during the HIU Repair Period), is your or your landlord’s responsibility as applicable.
This means that the costs associated with the repair or replacement of the HIU following the HIU Repair Period will be your or your landlord’s responsibility to pay for.
HIU Inspection Period means the period during which We are liable for the periodic inspection of the HIU only, which runs from the end of the HIU Repair Period until 30 June 2053 Taken from Definitions of the Residential Supply Agreement
During the HIU Inspection Period, we are responsible for carrying out the routine inspection of the HIU. The routine inspection is to be carried out once every two (2) years subject to Events Beyond Our Control, (Clause 11 of the Residential Supply Agreement). The HIU inspection shall as a minimum include:
We will provide a copy of our inspection report following any routine inspection which will set out our findings in respect of the HIU, including identifying any problems or issues affecting the HIU and any maintenance or similar steps that we recommend be carried out.
East London Energy are responsible for the maintenance, repair and/or replacement of the meter at all times.
During any HIU Inspection Period East London Energy may be asked by you or your landlord to repair or replace the HIU, or the Estate Management Company may ask you or your landlord to use East London Energy to repair or replace the HIU. In each case we will provide a quotation for any works and will only proceed upon confirmation that the costs have been accepted and payment received as appropriate.
