Swaffham Prior Heat Network - connection works

Step 5 to join the Heat Network - connection works

After the engineer survey and sign up to the Heat Supply Agreement, the next step is to connect your home to the Heat Network.

We have a contractor who carries out the connection works on our behalf.

We obtain all the relevant planning permissions, but you must inform your household insurer, mortgage provider or any other party with an interest in your property of the works.

Section 2 and Appendix 1 of the Heat Supply Agreement state the full terms and conditions for connection works.

Cost of connection works

There is a £1,000 fee for the connection work. Discounts are available to households that sign a Heat Supply Agreement (HSA) before 31 March 2022:

  • If you sign the HSA before 31 October 2021, we don't charge a connection fee
  • If you sign the HSA between 1 November and 31 December 2021, you qualify for a 75% discount
  • If you sign the HSA between 1 January and 31 March 2022, you qualify for a 50% discount
  • If you sign the HSA agreement from 1 April 2022 onwards, you have to pay the full fee

What is covered in the connection fee:

  • Removal and disposal of your existing oil boiler and tank
  • Installation of pipes connecting home to Heat Network
  • Installation of Heat Interface Unit (HIU) and heat meter

When connection works take place

We will only carry out connection works to your home once we have finished constructing the Energy Centre and Heat Network.

We make arrangements for connecting homes on a rolling basis throughout the year. We contact you to agree a timescale for connection works and a date for the start of the heat supply.

If, for any reason, we can't meet the agreed timescales, we will inform you of this.

What we install in your property

Each home that connects to the Swaffham Prior Heat Network requires the installation of an internal Heat Interface Unit (HIU). This box replaces your existing boiler. It is a similar size to a wall-hung boiler, measuring approximately 60cm x 48cm x 30cm.

We need to install an inlet and outlet pipe to the Heat Network. These pipes run from the main route in every street to the location of the HIU in your home. The survey of your home determines where to install the HIU and pipework in your home.

We also install a Heat Meter in your home, which monitors your heat and hot water usage.

What we remove from your property

We remove your existing oil tank and boiler.

We can dispose of both items for you, unless you would prefer to arrange this yourself.

How we carry out the connection works

We are responsible for works taking place at your home. When carrying out works at your home, our contractors will:

  • Leave property in a clean and tidy condition and remove any rubbish
  • Make good any area of your property affected by their works to the same condition as found at the start of works
  • Complete works within normal working hours - e.g. 9am to 5pm, Monday to Friday
  • Minimise health and safety risks
  • Minimise environmental disruption, nuisance and pollution

If you have any issues associated with connection works, please get in touch with our Heat Network customer services.

Household insurers

We can't give advice on individual home insurance policies. However, you should notify your insurer as early as possible about the work to your home. We can provide a statement that you can give to your insurers to assist those who may wish to sign up.

Further information

Where we cause damage, we will be liable for it and pay to repair it.

We will not fix any pre-existing faults with your home - e.g. the bottom of your oil tank had spilled as a result of long-term damage not caused by us - then we would not be responsible for this.

We have two options available:

  1. Replace 'combi' type boilers
  2. Replace 'system' type boilers

Our general preference is to deploy ‘combi’ type HIUs, as it is more efficient and provides better controllability of the network. However, we recognise that conversion may, in some cases, be cost prohibitive, or simply unacceptable to the end customer.

For those who wish to retain their indirect hot water tank (instead of converting to the combi-type), we conduct a risk assessment to assess whether or not safe storage temperatures can be achieved based on the above minimum inlet temperature. If there is any doubt, we would advise on switching to a combi-type HIU.
