Build your solar confidence
Know what good solar advice should look like.
A confident solar decision is not about becoming a technical expert. It is about knowing which questions matter, what evidence should be provided and who remains responsible after the installation is complete.
Confidence comes from clarity—not pressure
A system designed for your home
The design should reflect the roof, likely generation, household consumption and future plans—not a standard package selected before your needs are understood.
Figures with assumptions
Generation, savings and payback estimates should be explained as projections. Tariffs, usage patterns, shading and future energy prices can all affect the outcome.
Responsibilities that remain clear
You should know who is responsible for the survey, design, installation, certification, warranties, monitoring support and any technical problem after handover.
Seven checks before you commit
- Company assurance: Confirm that the contracting installer holds the relevant MCS certification and appropriate consumer-protection membership.
- Qualified delivery: Ask who will complete and supervise the work and how their competence is controlled.
- Technical basis: Check that the proposal is subject to a suitable survey and final design rather than treated as confirmed too early.
- Clear scope: Understand exactly which panels, inverter, battery, access arrangements, electrical work and documentation are included.
- Evidence: Ask how installation photographs, inspection results, commissioning information and handover records will be captured.
- Customer protection: Read the contract, cancellation terms, deposit protection and warranty information before agreeing.
- Aftercare ownership: Know who to contact if the system, monitoring or documentation does not meet expectations after installation.
Warning signs worth slowing down for
- A discount available only if you sign immediately.
- Savings or payback presented as guaranteed.
- A system recommended before energy use and property details are considered.
- Unclear answers about who holds the contract and warranties.
- Important exclusions hidden behind a headline price.
- No named route for questions, complaints or aftercare.
One review. Three useful outcomes.
A responsible assessment should not turn every enquiry into a sales appointment. It should help you understand the appropriate next step.
Solar appears suitable
Your property looks worth exploring further.
More information is needed
A material point needs checking before a sensible recommendation.
Solar may not be right
If that is our view, we will tell you clearly.
Compare the whole installation—not just the final figure
A fair comparison should include the system specification, roof and electrical work, scaffolding, DNO administration, bird protection where appropriate, certification, warranties, cancellation terms, handover and aftercare. A cheaper quotation is only cheaper if it genuinely includes the same standard of equipment, installation and protection.
Better-supported solar does not need to cost more.
Your handover should prove what was installed
The installation is not finished when the panels begin generating. Your handover should identify the installed system, electrical and MCS documentation, DNO correspondence, warranties, commissioning records, monitoring guidance, isolation information and the correct route for aftercare.
