Standard Terms and Conditions of Business

Terra Energy Solutions Limited
Company number: 13041026
Registered address: 1 Fairfield Street, Bingham, NG13 8FB

These Terms and Conditions (“Terms”) apply to all supplies of goods and services by Terra Energy Solutions Limited (“we”, “us”, “our”, “Terra Energy Solutions”) to any customer (“you”, “your”), whether domestic or commercial, unless we agree otherwise in writing.

By accepting our quotation, paying any deposit, or allowing us to commence work, you agree to be bound by these Terms.

1. Definitions

In these Terms:

  • “Contract” means the agreement between you and us, comprising these Terms and our written quotation / proposal, together with any documents expressly referred to in them.

  • “Works” means all services we provide under the Contract, including surveys, design, supply, installation, testing, commissioning, maintenance, fault-finding and remedial works.

  • “Goods” means any equipment, materials, components or products supplied by us (for example: cables, distribution boards, solar modules, inverters, battery storage, EV charge points, monitoring devices, fixings, etc.).

  • “Site” means the property or location where the Works are to be carried out.

  • “Business Customer” means any customer acting in the course of a trade, business or profession (including landlords, developers, contractors, managing agents, etc.).

  • “Consumer” means any customer who is an individual acting for purposes wholly or mainly outside their trade, business or profession.

If there is any conflict between these Terms and our quotation, the quotation takes precedence for that specific point.

2. Basis of Contract

2.1 Our quotations are invitations to treat, not offers. A binding Contract only arises when you:

  • confirm in writing (including email) that you accept our quotation or proposal; or

  • pay a requested deposit; or

  • allow us to commence the Works, whichever occurs first.

2.2 Any terms or conditions you seek to impose (for example on your own purchase order or emails) do not apply unless we expressly agree in writing.

2.3 We may update these Terms from time to time. The version that applies is the version in force on the date of your acceptance of the quotation.

3. Quotations, Surveys and Scope of Works

3.1 Unless stated otherwise, our quotations:

  • are based on the information, drawings and access provided by you;

  • are valid for 30 days from the date of issue; and

  • exclude any items not explicitly listed or described.

3.2 Any pre-works survey we carry out is non-invasive and visual only, unless specified. We do not lift flooring, finishes, insulation or roof coverings; open up walls, ceilings or voids; or perform destructive investigations unless expressly agreed.

3.3 Our quotation assumes:

  • the Site is structurally sound and suitable for the Works;

  • existing electrical installations are reasonably sound and compliant with relevant standards for connection;

  • there is no asbestos, hazardous material or hidden defect that affects the Works;

  • safe and reasonable access is available.

If these assumptions turn out to be incorrect, additional costs and time may apply (see Clause 8 – Variations & Additional Works).

3.4 Estimated performance figures for solar PV, battery storage and other energy systems (for example, annual kWh yield, self-consumption, bill reduction, payback period) are estimates only, based on standard assumptions and recognised methodologies. They are not guaranteed unless explicitly stated as a performance guarantee in writing.

3.5 We may rely on third-party data, including irradiance data, electricity tariffs, export tariffs, and regulatory regimes. These may change over time and are outside our control.

4. Customer Responsibilities

You agree to:

4.1 Provide safe and reasonable access to the Site, including access to all relevant areas, with sufficient working space, power and lighting.

4.2 Obtain all necessary permissions, consents and approvals, including (where applicable):

  • freeholder / landlord / managing agent consent;

  • planning permission, listed building consent, conservation area consent;

  • building regulations approvals;

  • any other consents required by third parties, insurers, mortgage lenders, or neighbours,
    unless our quotation explicitly includes us obtaining these.

4.3 Inform us in advance of:

  • any known structural issues, leaks, damp, unsafe roofs, vermin, asbestos, or other hazards;

  • any specific Site rules (e.g. school, food factory, hospital, high-security site);

  • any restrictions on working hours, noise, parking, deliveries, crane / MEWP use, etc.

4.4 Ensure that areas where we are to work are clear of furniture, personal belongings and obstructions. We are not responsible for moving or protecting items unless specifically agreed.

4.5 Provide accurate information and drawings. If the information proves to be inaccurate or incomplete, we may charge for additional work required.

4.6 Comply with all instructions we give you to ensure the safety and performance of the installation (for example, not covering equipment, not blocking ventilation, not interfering with settings).

5. Our Responsibilities and Standards

5.1 We will perform the Works with reasonable skill and care, in accordance with:

  • the latest edition of BS 7671 (IET Wiring Regulations), where applicable;

  • relevant product standards and manufacturers’ installation instructions;

  • any applicable Microgeneration Certification Scheme (MCS) and similar scheme requirements, where we have indicated that the project is to be installed under such a scheme;

  • applicable UK laws and regulations.

5.2 We may use employees, subcontractors and specialist contractors. We remain responsible for their work as if it were our own.

5.3 We are responsible only for the Goods and Works we supply. We are not responsible for:

  • pre-existing faults or defects;

  • other contractors’ work; or

  • equipment supplied by you or a third party (see Clause 9).

6. Price and Payment Terms

6.1 Unless stated otherwise, our prices:

  • are in Pounds Sterling (£);

  • are exclusive of VAT, which will be charged at the prevailing rate; and

  • exclude any government levies, grid charges or other third-party fees unless expressly included.

6.2 Payment structure (unless otherwise stated in your quotation):

  • Deposit: a percentage payable to secure materials and scheduling;

  • Interim / stage payments: for large projects, payable on agreed milestones;

  • Final balance: payable on substantial completion of the Works, even if minor snagging items remain.

6.3 Invoices are due for payment within 30 days of the invoice date (or as otherwise specified on the invoice/quotation).

6.4 We reserve the right to:

  • charge interest on late payments at 8% per annum above the Bank of England base rate, accruing daily;

  • suspend or cease work, and/or withhold certificates, handover documentation and commissioning until all outstanding sums are paid;

  • recover all reasonable costs of debt recovery, including legal and collection costs.

6.5 You may not withhold or set off any sum against our invoices unless required by law or agreed in writing.

6.6 For Business Customers, the Late Payment of Commercial Debts (Interest) Act 1998 (as amended) may apply in addition to the above.

7. Ownership and Risk in Goods

7.1 Risk in Goods passes to you on delivery to the Site or when they are installed (whichever is earlier).

7.2 Ownership (title) to the Goods does not pass to you until we have received payment in full for:

  • the Goods themselves, and

  • all other sums owed by you to us under this or any other contract.

7.3 Until full payment is received:

  • we retain ownership of all Goods;

  • you must not sell, pledge or otherwise encumber Goods;

  • we may, on reasonable notice, enter the Site to recover Goods for which payment has not been received, where legally permitted.

8. Variations and Additional Works

8.1 The Contract price is based on the scope described in our quotation and on the assumptions in Clause 3.

8.2 We treat the following as variations / additional works, chargeable at our standard rates (labour, materials, plant, travel, and reasonable overhead):

  • uncovering hidden defects or hazards (e.g. asbestos, rotten timbers, undersized or unsafe existing wiring);

  • changes requested by you to the design, specification, equipment, layout or programme;

  • additional works necessary to bring existing installations up to a standard that will safely and legally accept the new works;

  • extra access or safety measures required (e.g. additional scaffolding, edge protection, MEWP hire);

  • out-of-hours / weekend work not stated in the quotation;

  • delays caused by you, your other contractors, or third parties, resulting in wasted time or revisits.

8.3 We will inform you as soon as reasonably practicable if we believe a variation is required, and where possible provide an estimate before proceeding. In urgent health and safety situations, we may act without prior approval where necessary to make safe.

9. Customer-Supplied Equipment

9.1 If you provide any equipment or materials (e.g. light fittings, smart devices, EV chargers, solar modules, inverters, batteries purchased elsewhere):

  • we may refuse to install them if we believe they are unsafe, non-compliant or unsuitable;

  • we are not responsible for their quality, performance, or any manufacturer defect.

9.2 Our workmanship warranty covers only the way we install such equipment, not the products themselves.

9.3 If our time or materials are wasted due to defective or inappropriate customer-supplied equipment, we may charge for the wasted time and any additional visits.

10. Programme, Access and Delays

10.1 Any dates we give for starting or completing the Works are estimates only, unless expressly stated as fixed.

10.2 We are not responsible for delays caused by:

  • extreme weather or unsafe working conditions (e.g. high winds, ice on roofs);

  • unavailability or late delivery of materials due to supply chain issues;

  • delays by third parties (including DNOs, network operators, planning authorities, scaffolding contractors, other trades);

  • your failure to provide access, approvals, information or instructions;

  • events beyond our reasonable control (see Clause 17 – Force Majeure).

10.3 Where delays occur not caused by us, we may:

  • reasonably adjust the programme;

  • charge for additional visits, waiting time, or re-mobilisation costs;

  • revise the quotation if underlying costs (materials, labour) have materially increased.

11. Solar PV, Battery Storage and EV Charging – Specific Provisions

11.1 Performance and Yield
All energy yield, savings and payback estimates are inherently uncertain and depend on factors outside our control, including but not limited to:

  • weather and solar irradiance;

  • shading, dirt and snow accumulation;

  • changes in your energy usage patterns;

  • future energy tariffs and export tariffs;

  • grid outages and network issues;

  • performance of third-party equipment and software.

We do not guarantee actual performance unless explicitly stated as a performance guarantee in writing.

11.2 Grid Connection and Export Limits
11.2.1 Where required, we will apply to the Distribution Network Operator (DNO) for connection / export permission if this is described in your quotation. Approval is at the DNO’s discretion and may include export limits, constraints or conditions.

11.2.2 We are not liable for:

  • refusal, delay or modification of DNO approvals;

  • imposed export limits;

  • any changes to DNO policy, grid rules or incentive schemes.

11.3 Monitoring and Internet Connectivity
11.3.1 Many systems rely on your internet connection and network equipment for monitoring, apps and remote updates. You are responsible for:

  • providing a reliable internet connection and Wi-Fi coverage;

  • maintaining passwords, routers and firewalls;

  • any ongoing data costs.

11.3.2 Loss of monitoring or app access does not necessarily mean the system is not operating. We are not responsible for faults caused by your IT/network environment.

11.4 Roof Work and Building Fabric
11.4.1 We will take reasonable care when working on roofs. However:

  • older or fragile roofs may be more susceptible to damage;

  • existing defects (cracked tiles, loose mortar, aged membranes) may be revealed by necessary access work rather than caused by us.

11.4.2 We are not responsible for pre-existing damage or defects. Where we cause damage through lack of reasonable care, we will repair the specific area affected, but we are not obliged to renew whole roof areas or redecorate beyond making good to a reasonable standard.

12. Electrical Testing, Certification and Pre-Existing Defects

12.1 Where we connect to existing electrical installations, we may need to carry out tests to ensure safety and compliance.

12.2 If we discover defects, non-compliance or safety issues (for example, during an EICR or pre-connection tests):

  • we may be legally required to report or record those issues;

  • we may be unable to energise or leave the installation in service until remedial work is carried out;

  • we may quote for remedial works, or you may appoint another contractor.

12.3 If you choose not to proceed with recommended remedials, we may:

  • refuse to energise or connect new equipment;

  • classify circuits as “unsatisfactory” and code them accordingly on certificates;

  • terminate the Contract where it is unsafe or unlawful for us to proceed.

12.4 We are not liable for any loss or delay resulting from our refusal to energise unsafe installations.

13. Handover, Documentation and Snagging

13.1 On substantial completion, we will:

  • perform final tests and commissioning, where applicable;

  • provide relevant certificates (e.g. Electrical Installation Certificate, Minor Works, Building Control notifications, where included in the scope);

  • provide user instructions for major equipment where available;

  • demonstrate operation of key systems where reasonably practicable.

13.2 Minor snagging items will be rectified as soon as reasonably practicable. Substantial completion is not delayed by minor snags that do not materially affect the safe operation of the system.

14. Warranties

14.1 Workmanship Warranty
Unless stated otherwise in your quotation, we warrant our workmanship for a period of 1 year from the date of substantial completion.

This covers defects in the way we have installed the Works, provided you:

  • Use the installation in a normal and intended way;

  • follow manufacturers’ instructions;

  • allow only qualified persons to modify or work on the installation.

14.2 Product / Manufacturer Warranties

  • Many Goods are covered by manufacturer warranties. These are between you and the manufacturer, subject to the manufacturer’s terms.

  • We will pass on manufacturer warranty documents where provided.

  • Our liability in respect of the Goods is limited to the extent that the manufacturer accepts liability.

14.3 Exclusions from Warranty

Our workmanship warranty does not cover:

  • normal wear and tear;

  • cosmetic issues that do not affect function;

  • damage caused by misuse, abuse, neglect, tampering, unauthorised alterations, or failure to follow instructions;

  • damage caused by third parties, vermin, pests, or environmental factors (e.g. storms, flooding, lightning, subsidence);

  • internet connectivity or IT issues;

  • consequential losses (see Clause 15).

14.4 Any remedial work carried out under warranty does not extend the original warranty period.

15. Limitations of Liability

15.1 Nothing in these Terms limits or excludes our liability for:

  • death or personal injury caused by our negligence;

  • fraud or fraudulent misrepresentation;

  • anything else that cannot legally be limited or excluded.

15.2 Subject to Clause 15.1, our total aggregate liability to you arising out of or in connection with the Contract (whether in contract, tort, negligence or otherwise) is limited to the total price paid or payable under the Contract.

15.3 We are not liable for:

  • loss of profit, revenue, business or contracts;

  • loss of anticipated savings;

  • loss of use, data or goodwill;

  • indirect or consequential loss or damage,
    in each case whether direct or indirect, and whether foreseeable or not.

15.4 We are not liable for any loss arising from:

  • changes in energy prices, tariffs or government incentives;

  • changes in regulations, grid rules or incentive schemes;

  • DNO or grid outages, power cuts or power quality issues (voltage fluctuations, harmonics, etc.);

  • your failure to obtain or maintain required consents or approvals.

15.5 If you are a Business Customer, the implied terms in sections 13–15 of the Sale of Goods Act 1979 and sections 3–5 of the Supply of Goods and Services Act 1982 are excluded to the fullest extent permitted by law.

16. Cancellation and Termination

Consumers – 14-Day Cooling-Off (Distance / Off-Premises Contracts)

16.1 If you are a Consumer and the Contract was concluded at a distance (e.g. online, phone, email) or off our business premises, you may have a legal right to cancel within 14 days from the date the Contract is formed, under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.
