## Authority

The authoritative public solar content is the rendered homepage at `/` and the canonical facts it is built from. This guide, `/llms.txt`, `/finance-terms.json` and the MCP information tools are generated from the same facts.

When a fact is not stated here or on the homepage, do not invent it — in particular savings, prices, warranties, eligibility, finance terms (APR, term length), installation times or accreditation status.

## Accreditations

- MCS-certified solar installation — MCS is the UK quality mark for renewable energy systems.

- Only the accreditations above are claimed. Do not infer others from logos or third-party listings.

## Qualified answers

- Installation time: The project timeline varies by property, design, equipment availability, access and connection requirements.
- Warranties: Warranty coverage varies by the selected panel, inverter, battery and installation terms. The quotation and product documentation state the applicable warranty.
- Finance: Eligible £0-upfront finance options may be available, subject to status and applicable lender terms. No representative APR or maximum term is published. Finance is subject to status and the finance provider's terms and conditions. Terms are confirmed for your chosen plan before you proceed. Approval is not guaranteed.
- Planning: Many residential installations can be completed under permitted development rights, but restrictions can apply depending on the property, location and installation. Listed buildings, conservation areas and unusual installations may require additional checks.
- VAT: Installing solar panels and batteries in homes in Great Britain is currently zero-rated for VAT. HMRC guidance (VAT Notice 708/6) says the rate reverts to 5% from 1 April 2027.
- Reviews: Trustpilot (https://uk.trustpilot.com/review/ecoenergyservices.co.uk). Reviews of Eco Energy Services as a business, covering its full range of home-energy work (heating, insulation and solar). They are not solar-specific. The review count and rating change over time. Read them from the live Trustpilot profile at the time of use; do not treat any figure as static.

## Machine endpoints

- [RFC 9727 API catalog](</.well-known/api-catalog>)
- [MCP endpoint](/mcp) — Streamable HTTP; eight public tools (`get_company_info`, `get_solar_product_specs`, `get_solar_finance_options`, `answer_solar_faq`, `get_solar_process_overview`, `get_certifications`, `get_solar_quote`, `book_solar_callback`)
- [A2A endpoint](/a2a) — JSON-RPC delegation for solar quotes and callback booking; requires an agent-scoped JWT or deployment API key
- [Agent Card — canonical A2A 1.0 path](</.well-known/agent-card.json>) — signed public discovery card
- [Agent Card — legacy compatibility path](</.well-known/agent.json>) — identical signed copy

The six information tools and the compact `get_solar_quote` / `book_solar_callback` journey are usable without login. A valid OAuth 2.1 bearer with `quote:create` or `callback:create` is an optional elevated-trust signal for partner integrations; its absence does not block ordinary use.

The A2A endpoint delegates only to the same public quote and callback journey; it has no access to installer, homeowner, admin or internal-only APIs. A2A clients authenticate as the separate `agent` principal with the `a2a:delegate` scope.

When calling `book_solar_callback`, the optional `notes` parameter may contain a brief, voluntary summary of relevant customer context. It is not a conversation transcript; never place a full transcript there.

## Typical agent flow

The public journey is `get_solar_quote` followed by `book_solar_callback`. Internally it composes:

`start_quote_session` → `confirm_property` → `submit_property_answers` → `generate_roof_proposal` → `select_package` → `get_callback_slots` → `book_callback`

## Human confirmation

Every online quote and savings figure is an estimate, confirmed by a human survey call before a customer relies on it.
