Solar installation terms and conditions 

(Updated January 2026) 

Should you require this Contract or any information we have supplied in large print, please contact us. 

This document sets out the terms on which Eboracum Energy Studio Ltd (Company Number: 16897737) of 82A James Carter Road, Mildenhall, IP28 7DE (the “Company”, “we”, “us”) will provide solar photovoltaic (“PV”), battery storage and electric vehicle (“EV”) charge point installation services (the “Works”). 

Our core obligation is to perform the Works with reasonable skill and care, in line with applicable Building Regulations, the Institution of Engineering and Technology (IET) Wiring Regulations, and the design and installation standards associated with the Microgeneration Certification Scheme (“MCS”). Where MCS certification is required for a particular consumer outcome (for example, access to certain scheme benefits), we will make this clear before Contract formation and, if necessary, agree a compliant route to delivery. 

Your quotation will set out the goods and services we propose to supply, the total price (including VAT where applicable), and the intended timetable for supplying goods and carrying out the Works. It will also include performance information for the proposed technology. Where performance estimates are provided, they are prepared using recognised methods and assumptions and are indicative rather than guaranteed. 

We will discuss the design with you, including the proposed locations of key components. You will have an opportunity to approve the site design before Works commence. We may highlight approvals or permissions that are commonly required; however, it remains your responsibility to ensure any required consents are obtained and conditions complied with. Where we reasonably require evidence of approvals (and any related drawings/specifications), you must provide it. 

If additional third-party costs arise (for example, planning fees or structural engineer input), we may assist with guidance, but those costs remain your responsibility unless expressly stated otherwise. If you ask us to exclude an item or service that would ordinarily form part of a standard installation, that exclusion will be recorded in the quotation.

1.1 We will carry out the Works with reasonable care and skill and to a high professional standard. 

1.2 We will comply with applicable Building Regulations and other statutory requirements relevant to the Works.

This includes (without limitation) network reinforcement, service upgrades, unlooping, cut-out/service head changes, meter alterations, witness testing, G99 application fees, and any works required by the DNO or other third parties to enable connection or export. We may assist with applications and coordination, but third-party fees and mandated upgrade works are not included unless stated.

9. CHANGING THE WORK 

9.1 If you request changes, you must confirm them in writing within 14 days of first notifying us (where applicable). We will then adjust price and timetable as appropriate. 

9.2 We may implement changes required by local authority or utilities after giving written notice. 

9.3 Where you can secure amendments to such requirements, you must notify us in writing before the change is implemented; price/timetable will be adjusted accordingly.

9.5 If unforeseen work arises, we will explain options and seek instruction; this clause applies to that additional work. 

10. OUR EMPLOYEES, SUBCONTRACTORS OR TRADES 

10.1 You may not directly employ, instruct or divert our personnel/subcontractors for related works. If you do, you will pay us as if we had carried out those works. 

11. HEALTH AND SAFETY 

11.1 We are responsible for health and safety management for the Works. Where the Construction (Design and Management) Regulations apply, each party will comply with its respective duties. 

12. DELAY OR DISRUPTION 

12.1 If Works are delayed or extended for reasons outside our fault, we may adjust price/timetable under the variation provisions. 

12.2 If delay is caused by you (including lack of access or instructions), we may recover losses and reasonable expenses incurred.

13. YOUR RIGHT TO END THIS CONTRACT 

13.1 You have a right to cancel this Contract during the statutory cancellation period without giving any reason. 

13.2 To cancel, you must inform us by a clear statement (e.g., letter or email). It is sufficient to send the cancellation notice before the cancellation deadline expires. 

13.3 The cancellation period is 14 days and (where goods are supplied) begins on the day the last part of the goods is delivered. You may also cancel before any goods are delivered. 

13.4 You may cancel if there is an unreasonable delay in installation not caused by you. Where delay is outside our direct control and not caused by you, you may be entitled to a full refund. 

13.5 If you cancel this contract outside the cancellation period you may have to pay reasonable costs for any losses we may have incurred. We will attempt to keep these costs to a minimum. If you have paid us a deposit or any advance payments we may retain all or part of these payments as a contribution. 

13.6 If there is a serious delay within our control (and not yours), you may cancel and receive a full refund. 

13.7 If we are in serious breach, you may be entitled to cancellation and/or remedies such as repair, replacement, or compensation as required by law. 

13.8 Remedies apply where goods/services are misdescribed or not fit for purpose; they do not apply solely because you have changed your mind outside statutory rights. 

13.9 Rescheduling fee: if you request to change an agreed installation date with less than 72 hours’ notice, we may charge an administration and rebooking fee of £150 (plus any third-party costs already committed, such as scaffolding or delivery charges). 

14. EXPRESS CONSENT 

14.1 Consumer Contracts Regulations apply to certain domestic/distance or off-premises contracts. 

14.2 In such cases, cancellation rights typically run from contract signature and end 14 days after delivery of goods to the consumer’s home. 

14.3 For PV and battery installations it is often impractical to deliver all goods 14 days before Works start. Where you request Works to begin within the cancellation period, you may provide an express written request enabling an earlier start. 

14.4 If you make an express request, you can still cancel within the cancellation period provided the installation is not fully complete; however you must pay for work performed up to cancellation. Once installation is complete, cancellation rights may be lost and the full contract price may be payable. 

15. EFFECTS OF CANCELLATION 

15.1 If you cancel, we will reimburse payments received, including standard delivery costs, subject to lawful deductions for diminished value due to handling beyond what is necessary to assess goods. 

15.2 Reimbursement will be made without undue delay and in any event within statutory time limits, depending on whether goods are returned or services supplied. 

15.3 Refunds will use the same payment method unless you agree otherwise, and we will not charge fees for the reimbursement itself. 

15.4 Where applicable, we may arrange collection of goods at our expense; you remain liable only for diminished value resulting from unnecessary handling.

16. WORK BEGUN PRIOR TO EXPIRY OF THE CANCELLATION PERIOD 

16.1 If you have requested Works to begin before the cancellation period ends and later cancel, reasonable payment may be due for work carried out. You must confirm in writing that Works may commence early. 

16.2 Serious delay within our control may entitle you to cancel and receive a full refund. 16.3 Serious breach may entitle you to statutory remedies. 

16.4 Remedies do not apply merely because you changed your mind outside statutory cancellation periods. 

17. OUR RIGHT TO SUSPEND OR END THIS CONTRACT 

17.1 We may suspend or terminate without prejudice to other rights if: (a) you fail to pay an interim invoice and remain unpaid 7 days after written demand; (b) you or your agents obstruct or interfere, or fail to provide site access without good reason; (c) insolvency events occur; or (d) your fault causes delay for more than 14 consecutive days. 

17.2 If suspension occurs and you remain at fault, we may terminate and recover sums due, reasonable suspension/termination costs, and losses including loss of profit, subject to law. Your legal remedies remain unaffected. 

18. EXTENDING THE CONTRACT PERIOD 

18.1 The contract period will be extended by a reasonable period to allow for: delayed or missing instructions; variations; delayed choices of materials; suspension; matters outside our control; adverse weather; and wider events such as civil commotion, industrial action or lockdowns. 

19. SUBCONTRACTING 

19.1 We may subcontract any part of the Works. Where we do, we remain responsible for the subcontracted Works as if performed by us. 

20. CLEARING THE SITE 

20.1 On completion we will remove surplus materials, waste, tools and any temporary works we supplied and leave the site reasonably clean and tidy. 

20.2 We are not responsible for removing items placed on site by you or by persons outside our control. 

21. RELATED CREDIT AND ANCILLARY AGREEMENTS 

21.1 If this Contract is cancelled, any linked credit agreement and ancillary contracts connected to this Contract will be treated in accordance with applicable consumer credit rules and may be automatically cancelled where required. 

22. TIMETABLE FOR WORKS 

22.1 We will agree a timetable with you for delivery and installation. 

22.2 Timetables may need to change due to weather or availability. We will notify you as soon as reasonably practicable and agree a revised timetable.

22.3 Where severe supplier delays occur, we may propose equivalent specification/value products. Where scheme rules require specific certification, we will only propose compliant products. You may accept the alternative, wait, or cancel without penalty where legally entitled. 

22.4 If severe delay is caused by us or our suppliers and would be considered severe by a reasonable person, you may cancel without penalty. 

22.5 If delay is caused by you, we will try to accommodate without charge, but if third-party costs arise (e.g., extended scaffold hire) you will be responsible for those costs. 

23. DEPOSITS, ADVANCE PAYMENTS AND GOODS PURCHASED 23.1 Deposits and advance payments may only be applied to costs and Works under this Contract. 

23.2 Where required by the applicable consumer code, deposit payments and the workmanship warranty will be protected by insurance-backed protection. Details of the provider will be supplied upon request. 

23.3 Where goods are purchased using your deposit/advance payment, you will obtain title to the proportion paid for. We may deliver to you or store separately, clearly marked as your property, and insured until delivery. 

23.4 Deposits will not exceed 25% of the total contract price. If you cancel within the statutory cancellation period, the deposit will be returned promptly, subject to lawful deductions for work performed where applicable. 

23.5 If additional advance payments are agreed, total deposits and advances will not exceed 60% of the contract price. 

23.6 We will not request advance payments more than 3 weeks before an agreed delivery/installation date. 

23.7 If a deposit is taken before a full technical assessment and we cannot proceed due to issues discovered, deposits/advances will be returned. 

23.8 The quotation will set out invoice timings and payment amounts due at each stage. 

24. GOODS BELONGING TO US 

24.1 Goods that remain our property must be kept identifiable and protected from damage and stored in original packaging where possible. Contact us if you believe goods create a hazard. 

24.2 If the Contract ends, we will arrange collection. We will reimburse any portion you have paid for, subject to reasonable costs incurred. If reasonable collection arrangements are not provided, we may take steps to recover goods or value. 

25. CHANGES TO THE PLANNED WORK 

25.1 If you request changes after signing, contact us promptly. We will accommodate where reasonably practicable and explain where not possible. 

25.2 Where changes are agreed, you must confirm the request in writing within 14 days. 

25.3 Changes may adjust the cost; any adjustment will be handled as a formal variation with written agreement. 

25.4 If unexpected work arises, we will discuss options. If within our competence we will quote for it; if outside our competence we will assist you in finding a suitable contractor. Delays caused by such issues may result in reasonable delay charges.

26. MEDIATION AND ARBITRATION 

26.1 If a dispute cannot be resolved, you may refer it to the dispute resolution procedures of the applicable consumer code (where within remit). We will participate where required. 

26.2 Mediation aims to reach a practical resolution without court proceedings in a reasonable timeframe. 

26.3 If mediation does not resolve matters, you may be able to refer the dispute to independent arbitration. Fees and refund rules depend on the arbitration provider. 

26.4 Arbitration awards are final and legally binding, subject to limited statutory grounds for challenge. 

26.5 Disputes relating specifically to installer standards may also be referred to the relevant certification body/standards route, where applicable.
