​

7. Regulatory Compliance

Whether you choose to install the product yourself or engage a qualified professional, all electrical installation work must comply with applicable UK legislation and standards. This includes, but is not limited to:

 

  1. BS 7671:2018+A2:2022 (IET Wiring Regulations), particularly Regulations 411 (protection against electric shock), 433 (overcurrent protection), 462 and 537 (isolation and switching), 712 (solar photovoltaic systems), and Chapter 82 (prosumer installations);

  2. The IET Code of Practice for Grid-Connected Solar Photovoltaic Systems (3rd Edition), covering requirements for cable sizing, grid connection, anti-islanding protection, and battery system integration;

  3. Approved Document P of the Building Regulations 2010 (Electrical Safety – Dwellings), including relevant notification requirements and the need for work to be carried out by a Competent Person Scheme (CPS) registered electrician where applicable;

  4. ENA Engineering Recommendation G98/1-8 (2021), concerning the connection of microgeneration systems (≤16 A per phase) to the public distribution network.

 

Any alterations to your property’s wiring—such as connecting a microinverter, modifying a consumer unit, or installing an isolator—must be completed either by an electrician registered under a recognised Competent Person Scheme, or must be notified to your local Building Control body prior to the commencement of works.

 

If you elect to carry out the installation yourself, it is your sole responsibility to ensure full compliance with all applicable legal and safety requirements. This includes, where required, undertaking all necessary commissioning tests (such as RCD testing, earth fault loop impedance testing, and anti-islanding verification) and notifying your local Distribution Network Operator (DNO) within 28 days of commissioning, in accordance with ENA G98, where applicable.

 

All relevant documentation—such as the Electrical Installation Certificate, Building Regulations Compliance Certificate, and commissioning test records—must be properly completed and retained.

 

Thunder Energy Services LLC shall not be liable for any damage, regulatory non-compliance, or safety risk arising from incorrect, incomplete, or unauthorised installation.

​

8. Suitability of Property and Electrical Supply

Before installing your solar kit, it is essential to ensure that your property is suitable for the installation. This includes verifying that your existing electrical supply infrastructure is capable of safely accommodating the additional energy generated by the system. You must also assess the intended installation area—whether a balcony, terrace, patio, garage, or garden space—to confirm that it is structurally sound and capable of supporting the weight of the equipment.

 

If any structural modifications or reinforcements are necessary to comply with applicable safety or building regulations, it is your sole responsibility to arrange for and complete such works prior to installation.
 

9. Planning Permission

The customer is solely responsible for determining whether planning permission is required for the installation of the system. In cases of uncertainty, the customer should consult their local planning authority or refer to the UK Government’s Planning Portal (https://www.gov.uk/planning-permission-england-wales) guidance.
 

10. Installation Risk and Liability
All installations are undertaken at the customer’s own risk. Thunder Energy Services LLC accepts no liability for any loss, damage, or personal injury arising from or in connection with the installation process. The installation manuals provided are intended for general guidance only and do not constitute professional advice. Customers must exercise their own judgement and ensure compliance with all applicable local regulations, building standards, and health and safety legislation. Where there is any uncertainty, customers are strongly advised to consult a suitably qualified professional.

 

Thunder Energy Services LLC shall not be held liable for any incorrect, unsafe, or non-compliant installation carried out by the customer or on the customer’s behalf.
