Frequently Asked Questions
What is my Core tariff?
There are different tariffs depending on the type of resident you are. Please click on the below tariff document appropriate for your situation.
Please note retail units are dealt with on a case-by-case basis. Please contact us for more information.
All unit rates and charges include VAT at 5%
I’m a landlord and want my tenants to pay their bills – How do I do this?
If you are a landlord it is your responsibility to provide the Heat Supply Agreement and Registration Form to your tenants to sign and return to Core via email. The account for the property will then be created in the tenant’s name and all bills will be sent to that tenant. This process must be repeated for each change of tenancy.
Incorrect Heat Supply Agreements will not be accepeted as a binding contract and it is imperative to ensure the correct contract is filled in and completed infull.
Why do we have a district heating network?
As part of the planning requirements to build Eddington the development was required to include a District Heating Network. As well as this the North West Cambridge Development is committed to creating a sustainable community. Innovative and unique sustainability initiatives are built into every aspect of our community, to minimise the environmental impact of the development and offer a high quality of life.
How does the Energy Centre and District Heating Network work?
At Eddington, there is a centralised heating system, which combines an Energy Centre and a District Heating Network. Together this delivers hot water directly to each property from the central shared supply. The heat distribution network provides all of the heating and hot water requirements, without the need for individual gas boilers within the homes. The primary elements of the system are as follows:
The Energy Centre is the central location where heat and hot water is generated.
Heat Interface Unit (HIU)
This is the heat unit within each home, which delivers heating and hot water. The HIU enables individual temperature control within the home, and allows for each home to be individually metered for its own heat and hot water use.
Heat Metering and Billing
Each HIU has a heat meter which enables heat used to be billed to each dwelling on a periodic basis.
The distribution network is the system of pipes distributed across the development to deliver hot water to each home.
How is CORE Greener?
The central plant reduces emissions by heating the water used for all buildings, instead of hundreds of gas boilers all working to heat small amounts of water that may not be used. This means Core only produces heat that is used, with far less waste and excess emissions.
Does CORE Use Renewable Energy?
The Core central plant is gas fuelled. However, the way in which heat is generated and transferred results in a more efficient system than a traditional individual boiler. The energy centre also has a provision of a Combined Heat and Power system to further reduce inefficiencies.
Core did look into using alternative sources of fuel but they would have been unreliable, less available and inappropriate for a residential development. Please be assured that we have left room in the energy centre to switch to other methods of energy production with future-proof technology.
We would also like to reassure residents that Eddington uses a large number of photovoltaic panels which are on the roof of most buildings on the development which contributes to our renewable energy strategy. There is also an extensive water recycling system on the development to reduce water wastage and all buildings on the development are at Level 5 against the industry-recognised Code for Sustainable Homes or BREEAM Excellent for non-residential buildings.
How is this different from a traditional gas bill?
The misleading issue with comparing Core to other utility companies is that we charge you for the amount of heat and hot water that your home uses. Other companies charge you for the gas provided to your home. Gas and heat, while they are both measured in kWh, cannot be compared readily on a like-for-like basis as it does not take energy losses and efficiencies associated with conventional gas systems into account.
But my Energy Performance Certificate says I should be paying less?
The Energy Performance Certificate is a very general estimate of how much energy a home uses. This is a Government-designed document that is a “one size fits all” estimate.
- It does not take any electrical energy use beyond lighting (e.g. white goods, cooking, electrical items, etc.) into consideration
- It uses a basic occupancy and home usage template, and based on UK average weather data
- It uses out-of-date pricing data, so costs are not in line with current market rates
This can create much confusion for customers across the energy industry, but all utility companies are required to produce the certificate, even if it is inaccurate.
How can I reduce my bill?
As your usage costs are based on how much heat your home actually uses, your bill will go down if you cut usage. Here are some tips on how to save:
