Your Solar Installation T&C's

Terms & Conditions for the installation of Octopus Energy Solar PV & Home Battery systems

1. Introduction

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 solar photovoltaic (PV) system.

1.2 For the purposes of these terms, “solar PV” and “solar PV system” mean the solar photovoltaic panels, inverter, storage battery, controls, electrical hardware, wiring, fittings, ancillary components, any external modifications to the home including the roof, any internal modification to the home, earthworks, and other materials installed as part of the agreed solar PV 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 solar PV system at your property you must complete our application form accurately and in full, have the legal right to have the solar PV 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 solar PV system and/or associated components have not already been installed). Where your solar PV system has already been installed either in part of in full:

3. Our Charges

3.1 If we consider your property is likely to be suitable for a solar PV system, we will provide you with a price for this work (the “Fast Quote”). The Fast Quote is an estimated price based on the information you provided, and entitles you to the following standard installation components and materials:

3.2 Your Fast Quote price includes the labour costs to complete your “Standard Installation”. A Standard Installation is an installation requiring only minor modifications to your home’s interior and exterior finished surfaces and adjacent grounds. Standard Installation labour does not include major modifications to your home’s roof, walls, or any structural members, any underground works, or other works deemed abnormal by our solar PC installation experts.

3.3 Any Fast Quote that we provide is based on your answers about the relevant technical details of your home, which you provided to us as part of your application. Where we determine the technical details of your home differ from the answers you provided, we reserve the right to void your Fast Quote and issue a new quote or quotes based on those details in line with clause 4.2 below.

3.4 The Fast Quote does not include changes to your home’s electrical service that your Distribution Network Operator (DNO) may require, such as unlooping, or a three-phase (3-phase) power connection. If your home requires a main fuse (service cut-out) upgrade, we may be able to undertake these works for you, but where we are not allowed to do these additional works, your DNO may levy a separate charge for doing them.

3.5 Any Fast Quote we provide constitutes a fixed price for a Standard Installation that meets or exceeds Microgeneration Certification Scheme (MCS) standards and is not subject to reduction or discount from any customer-requested modifications of the system design.

3.6 Any Fast Quote that we provide will be valid for thirty (30) days.

3.6.1 Should you wish to proceed with your Fast Quote after such time, we may, at our
discretion, elect to issue a new Fast Quote.

3.6.2 After such time, where we have failed to contact you after reasonable attempts,
we may, at our discretion, cancel your Fast Quote.

3.7 In the event that we issue a Fast Quote with incorrect details (including price), we
may at our discretion, issue a corrected Fast Quote based on the information you

3.8 To accept the Fast Quote and proceed with the installation of a solar PV system, you
must make a £500 advance payment via a payment system provided to you via
webpage or email. This advance payment is fully refundable as set out in clause 4 below.

4. Site Survey and Suitability

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 may, at our discretion, elect to conduct an on-site survey following the payment of your advance payment in line with clause 3.6 to assess whether your property is suitable for our solar PV 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 additional cost. This quote shall either be a separate “Additional Works Quote” or an amended final sale price in your final sale contract, which we will issue to you following completion of your home survey and solar PV system design (the “Contract Pack”).

4.3 You may elect to accept the Additional Works Quote or Contract Pack via a link provided to you by web or email. Payment will due upon completion of the solar PV system installation in line with section 7. Should you not wish to accept the Additional Works Quote or the Contract Pack, we will refund your advance payment in full.

4.4 Where we identify factors that prevent us from completing an installation even with additional works, we will refund your advance payment in full.

4.5 Where we deem your home to be suitable for a solar PV installation in accordance with our Standard Installation service criteria and any required Additional Works, we will perform the installation with reasonable skill and care, in a good and workmanlike manner and in accordance with the standards set by the MCS. We shall comply with all applicable laws.

4.6 The exact make and specification of all components and materials shall be at our sole discretion and any changes to the specified schedule of materials and components, including any requested third-party components or materials, will be at our discretion.

4.7 We will not make use of components or materials that cause, or are likely to cause, the installed solar PV system to fail to meet MCS performance standards.

5. System performance

5.1. We will provide you with an estimated output factor for your system.

5.2. Where we determine environmental shading will affect your solar PV system, we will estimate your output factor based on a methodology that is functionally equivalent to the MCS methodology, but that allows for use of an extended performance scale to deliver accurate calculations for larger solar PV arrays.

5.3. We guarantee your system will, at the time of installation and commissioning, deliver at least 90% of the energy output (in kWh) figure given in your performance estimate based on the environmental shading and other known factors that we are reasonably able to incorporate into your performance estimate at the time the estimate was issued.

5.4. Where we are unable to ascertain some system characteristics directly, your system performance calculation may be undertaken using assumed values for array orientation, roof & panel inclination, and environmental shading. Actual performance may be significantly lower or higher if the characteristics of the installed system vary from the assumed values.

5.5. If we have had to estimate or take remotely any of the factors that affect this estimate, we will carry out a full site survey before installation commences. If this survey results in a lower performance estimate than in this quote, you may choose to continue with the installation under the new performance estimate or exercise your cancellation rights per section 6.

5.6. Please note that any information provided in relation to your product (including but not limited to the performance, suitability, output, potential savings) are provided as estimates only and are not binding representations, statements, undertakings, warranties, guarantees or promises as to the outcome of the product.

6. Cooling off period and Rescheduling Your Installation Date

Where you ask us to do this, you agree that we can charge you for any goods delivered or services carried out by us up to the point you notify us that you wish to terminate the Installation Contract, as detailed in clause 2.2.

6.4. After your 14-day cooling off period has expired, you have a further “risk-free” cancellation period that runs until the earlier of 24 hours prior to your agreed installation date, or 17:00 UK time on the last business day prior to your scheduled installation. During this time you can cancel the Installation Contract for any reason and request a full refund of your advance payment.

6.5. After the expiration of the “risk-free” cancellation period in clause 5.4, you may still cancel the Installation Contract and request a refund of any monies paid to us, but we will deduct any applicable charges for any goods delivered and services carried out by us up to the point you notify us that you wish to terminate the Installation Contract, as detailed in clause 2.2.

6.6. Where you have accepted the Installation Contract and we are unable to contact you for a period of thirty (30) days following reasonable attempts, we may, at our discretion, cancel your Installation Contract and refund any monies paid to us. We will deduct any applicable charges for any goods delivered and services carried out by us up to the point your Installation Contract is cancelled due to lack of contact.

6.7.
