      The Quote is an offer from us to you to enter a legally binding contract with us and is valid for 60 (sixty) days from the date it is issued.

    3. 4.3.

      The Quote will set out important information about your Solar PV system and any other components included within our service and will state the price for the system fully installed as well as providing an estimate of how much your system will generate, what type of financial savings and financial benefit the system will deliver and how energy independent you can become.

    4. 4.4.

      The figures detailed in the Quote are produced based on all the information we know at the time about your property, roof space, shading impacts and your annual energy consumption profile and are estimates only that do not constitute a guarantee of generation, savings or financial benefit.

    5. 4.5.

      You should ensure you fully understand your Quote, and that all the information that has been detailed within the Quote is accurate and contains no errors.

    6. 4.6.

      The contract will become binding once you sign or e-sign to accept your Quote.

    7. 4.7.

      Once the contract is entered (i.e. written acceptance provided), a Survey appointment will be made with you. Following the Survey, we will confirm your property’s suitability for the Solar PV and/or battery storage system and will notify you if any additional works, other than the Works detailed in your Quote, will be required.

    8. 4.8.

      If your property is suitable for the Solar PV and/or battery storage system detailed in your Quote, with no additional changes or amendments required, we will make arrangements with you for the installation Works and scaffolding access. 4.9 If changes are required to be made to the Quote or if your property is deemed as not suitable for Solar PV panels, we will follow the process as set out in clause 5.

  5. 5.


    1. 5.1.

      The Survey Fee covers the cost of the assessment of your property and verification of its suitability for the Solar PV and/or battery storage system we have quoted for. Payment of the Survey Fee, our acceptance to carry this out, or our carrying out of the Survey do not constitute confirmation that your property is suitable for the Solar PV and/or battery storage system and your Survey Fee is non-refundable in such an instance.

    2. 5.2.

      The Survey aims to identify the suitability of your property for the Solar PV and/or battery storage system we have quoted and will check the roof structure and its ability to carry a Solar PV system according to industry standard roof calculations. Should any concerns about the structure of your roof be identified, we will ask a structural engineer to review the calculations. We do not take any responsibility for the structural integrity of the roof, the compliance of the electrical system at the property or the condition of the property. Any structural, electrical or roofing pre-works will be the sole responsibility of the property owner.

    3. 5.3.

      We will always aim to deliverthe Solar PV and/or battery storage system as specified and priced in the Quote you have accepted. We provide your Quote prior to the Survey and because of this certain characteristics and values have been estimated or assumed. We estimate the performance of the Solar PV system by considering the capacity of the Solar PV system (kWp), the estimated solar irradiance based on location, the pitch and orientation of your roof and the shading factor. We calculate the performance in line with MCS standard calculations as detailed in the MCS Guide to the Installation of Photovoltaic Systems 2014.

    4. 5.4.

      The performance estimate, expected generation, return or efficiency of the Solar PV system may change from the initial Quote, if for example;

      (a) the information you provide us about your property is incorrect; or

      (b) our Survey reveals additional information about the property which was not known to us at the time we provided the Quote, and at all times the estimate is not a guarantee of anything set out in it.

    5. 5.5.

      If we are unable to provide the Solar PV and/or battery storage system as described in your initial Quote, we will contact you to discuss and agree any changes to your Quote, this may mean a change to the price in your Quote. If we cannot agree changes to your Quote or your property is deemed unsuitable for a Solar PV system, We or You will hold the right to cancel the contract. Details on cancellation are available in clause 3.

  6. 6.

    Changes to your Contract

    1. 6.1.

      If you wish to make a change to the scope of Works set out in the agreed Quote after the contract has been entered, you will need to consult with us. We may be able to accommodate such changes provided they are technically possible, and any necessary provisions or permissions are in place. Any changes requested by you may mean extra costs to the agreed Quote. If we agree to the changes, we will issue you with a revised Quote. As per clause 3 your new Quote will include a new cancellation period of 14 (fourteen) days.

    2. 6.2.

      If we discover during the Works that additional works are required, due to electrical, roofing or structural works that have been carried subsequent to the survey which directly impacts our ability to carry out the works we will tell you and ask how you wish to proceed. In this instance we shall;

      (a) Agree with you, any additional or varied works we need to carry out;

      (b) Agree with you and additional charges that may apply in these circumstances;

      (c) Issue you with a revised Quote, which would incorporate a new cancellation period in accordance with clause 3; and
