Terms and Conditions for the installation of Octopus Energy heat pump systems

Version 2 – last updated on 28th February 2023


1.1 These terms and your Fast Quote and (if applicable) any Additional Works Quote shall form the contract between you and Octopus Energy Services Limited (company number 10434397) (“we”, “us”, “our” and “Octopus”) for the installation of your heat pump system.

1.2 For the purposes of these terms, “heat pump” and “heat pump system” mean the heat pump unit, water cylinder, controls, electrical hardware, wiring, pipes, fittings, valves, radiators, and any external modifications including earthworks, barriers, and other materials installed as part of the agreed heat pump system design.

1.3 These terms are based on the information you have provided to us in your online application form. If any of this information changes you must let us know immediately as it may impact your Fast Quote and/or our ability to complete your installation. By completing an application form you confirm that you agree to be bound by these terms.

2. Eligibility

2.1 To be eligible for us to install a heat pump system at your property you must accurately complete our application form in full, have the legal right to have the heat pump system installed (both internal and external to your home) and obtain any required planning or building approvals required for your installation (collectively referred to as the “Eligibility Criteria”).

2.2 If any of the Eligibility Criteria have not been satisfied we will not complete the installation until they are (assuming the heat pump and/or associated components have not already been installed). Where your heat pump system has already been installed either in part or in full:

(a) you shall be liable for all costs of the installed heat pump system parts and their installation; and

(b) you shall be liable for all costs of materials deemed unfit for future use regardless of whether they have been installed at your property yet; and

(c) you shall indemnify us for all claims, liabilities, costs losses and expenses (including third party claims and legal fees that we may incur arising from or in connection with the installation of the heat pump and/or associated components).

3. Our Charges and Boiler Upgrade Scheme (“BUS”) Application

3.1 If we consider your property is likely to be suitable for a heat pump system, we will provide you with a price for this work (the “Fast Quote”) which assumes that your property requires a standard installation service only, as described on our website here (a “Standard Installation Service”).

3.2 Any Fast Quote or Additional Works Quote that we provide will be valid for seven days.

3.3 To accept the Fast Quote and proceed with the installation of a heat pump system, you will need to make a £500 deposit via the link provided to you via webpage or email. This deposit is fully refundable in line with Clause 4.1.

3.4 Where you wish to apply for the government Boiler Upgrade Scheme (BUS) grant, we will use the information you provide us to submit the application form on your behalf. Where your application is unsuccessful or if the BUS grant ceases to be available, you will need to pay the difference to us before we can proceed with your installation.

4. Site Survey and Installation

4.1 Even where you meet the Eligibility Criteria, there may be other factors which would prevent us from completing the installation or which would require additional works to be carried out first. We will therefore conduct an on-site survey following the payment of your deposit in line with Clause 3.3, to assess whether your property is suitable for our Standard Installation Service. We will advise you if we are unable to proceed with a Standard Installation.

4.2 Where we identify that your home is not eligible for our Standard Installation Service, but that an installation is possible provided additional works are completed (“Additional Works”), we shall contact you and provide you with a quote for the cost of this (the “Additional Works Quote”). You may elect to accept the Additional Works Quote via a link provided to you by web or email. Payment for additional works will due upon completion of the heat pump installation. Should you not wish to accept the Additional Works Quote, we will refund your deposit plus an additional one-time goodwill payment of £5.

4.3 Where we identify factors that prevent us from completing an installation even with additional works, we will refund your deposit plus an additional one-time goodwill payment of £5.

4.4 We will perform the installation with reasonable skill and care, in a good and workmanlike manner and in accordance the standards set by the Microgeneration Certification Scheme (MCS). We shall comply with all applicable laws.
