Terms & Conditions

Last updated: March 2026

1. About Us

Depth of Light Ltd ("we", "us", "our") is a company registered in England and Wales. Company registration number: 13826448. Registered address: First Floor 2, Bond Avenue, Bletchley, Milton Keynes, MK1 1SW.

These terms and conditions govern your use of our website at depthoflight.co.uk and any services we provide to you. By using our website or engaging our services, you agree to be bound by these terms.

2. Quotations and Estimates

All indicative costs provided via the website calculator or verbally are estimates only and are subject to a site survey. A fixed written quotation will be issued following the survey. The price stated in the written quotation is the price you will pay — no additional charges will be applied without your prior written agreement.

Quotations remain valid for 30 days from the date of issue unless otherwise stated. After 30 days, material costs may have changed and we reserve the right to issue a revised quotation.

3. Acceptance and Formation of Contract

A binding contract between us is formed when you accept our written quotation in writing — either by email confirmation or by signing and returning the quotation form — and we confirm receipt of your acceptance. Verbal acceptance alone does not form a binding contract.

These terms and conditions are incorporated into every contract we form. In the event of any conflict between these terms and any specific terms in your written quotation, the written quotation will prevail.

4. Payment Terms

Full payment terms are set out in your individual written quotation. Our standard terms are:

  • A deposit (typically 25–50% of the contract value) is required on acceptance to confirm your installation date and allow materials to be ordered
  • The balance is due on the day of installation completion, before our engineers leave the site
  • Where materials require advance ordering, a higher deposit may be required — this will be stated in your quotation

We accept payment by bank transfer (BACS) and card. Invoices unpaid after 14 days may incur a late payment charge of 8% above the Bank of England base rate under the Late Payment of Commercial Debts (Interest) Act 1998.

5. Installation

We will carry out all work in a professional and workmanlike manner, in compliance with all relevant regulations including MCS standards, Part P Building Regulations, BS7671 (IET Wiring Regulations 18th Edition), and manufacturer installation requirements.

On completion of qualifying works, you will receive:

  • MCS installation certificate (solar panels and battery storage)
  • Part P Building Regulations certificate (electrical works)
  • Commissioning report and system documentation
  • Warranty documentation for all installed equipment

You are responsible for ensuring safe and unobstructed access to the property and all relevant work areas on the agreed installation date. Where access is restricted by circumstances not identified at survey, additional charges may apply — we will discuss this with you before proceeding with any additional work.

6. Your Responsibilities

You confirm that you have the legal right to authorise installation works at the property. For rented properties, you confirm you have obtained the necessary written permission from your landlord.

You are responsible for ensuring the property's electrical installation is in a safe and serviceable condition. If our engineers identify a pre-existing electrical fault that affects safe installation, we reserve the right to pause works until this is resolved.

7. Workmanship Warranty

We provide a 10-year workmanship warranty on all solar panel and battery storage installations, and a 2-year workmanship warranty on EV charger installations. This warranty covers defects arising from the quality of our installation workmanship.

The workmanship warranty does not cover:

  • Equipment failure (covered separately by manufacturer warranties)
  • Damage caused by third parties, extreme weather events, or acts outside our control
  • Normal wear and tear
  • Modifications to the installation carried out by others without our prior written consent

Equipment warranties are provided by the relevant manufacturers and are detailed in your installation documentation. We will assist you in submitting manufacturer warranty claims where required.

8. Your Right to Cancel

As a consumer, you have the right to cancel your contract within 14 days of formation without giving any reason, under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.

To cancel within the 14-day period, notify us in writing by email to info@depthoflight.co.uk or by post to our registered address. Any deposit paid will be refunded within 14 days of cancellation, provided no materials have been ordered or work commenced at your request.

If you request that works commence within the 14-day cancellation period, your right to a full refund may be reduced proportionately to work completed.

Cancellation after the 14-day period but before the installation date may result in loss of deposit where materials have been ordered. Cancellation after installation has commenced will be charged at the proportion of work completed, plus materials that cannot be returned.

9. Complaints Procedure

We take all complaints seriously. If you are unhappy with any aspect of our service:

  1. Contact us directly in the first instance — by phone on 07516 762540 or email at info@depthoflight.co.uk
  2. We will acknowledge your complaint within 2 working days and aim to resolve it within 14 working days
  3. If your complaint relates to an MCS-certified installation and cannot be resolved directly, you may refer to the Renewable Energy Consumer Code (RECC) for independent dispute resolution

10. Limitation of Liability

Our total liability to you under or in connection with any contract is limited to the value of that contract. We are not liable for any indirect, consequential, or economic losses, including loss of profits, savings, or data.

Nothing in these terms limits or excludes our liability for:

  • Death or personal injury caused by our negligence
  • Fraud or fraudulent misrepresentation
  • Any liability that cannot be excluded by law under the Consumer Rights Act 2015

11. Data Protection

We process your personal data in accordance with UK GDPR and the Data Protection Act 2018. For information on how we collect, use, and store your personal data, please see our Privacy Policy.

12. Intellectual Property

All content on this website — including text, images, design, and code — is owned by or licensed to Depth of Light Ltd. You may not reproduce, distribute, or use any content from this website for commercial purposes without our prior written consent.

13. Governing Law

These terms are governed by the law of England and Wales. Any disputes arising from these terms or any contract between us will be subject to the exclusive jurisdiction of the courts of England and Wales.

14. Changes to These Terms

We may update these terms from time to time. Updates will be published on this page with a revised date. The version applicable to any specific contract is the version in force at the time that contract is formed — changes do not apply retrospectively to existing contracts.
