Published by SEO-DONS LTD (company no. 16766013), 71-75 Shelton Street, Covent Garden, London WC2H 9JQ. You can check the company on the Companies House register. The guide has no named authors; it is written and checked by the publisher.
How it is paid for
SEO-DONS LTD is a commercial company that runs websites like this one. The guide carries no adverts. Questions sent through the site come to SEO-DONS LTD, and we answer them by email. If that ever changes, this page will say so.
Where the facts come from
Every figure on the site comes from a published source, and each page links to its sources next to the figure and again at the foot of the page. The main ones are:
- Generation: PVGIS 5.3 from the European Commission's Joint Research Centre, run for central Manchester over eight roof directions and eight pitches.
- Prices: the annual solar and battery cost data from the Department for Energy Security and Net Zero, drawn from the national installation database.
- Housing: the 2021 Census, the Valuation Office Agency's 2026 property counts and the ONS energy-efficiency statistics.
- Rules: the planning legislation itself, Manchester City Council, GMCA, SP Electricity North West, Ofgem and HMRC.
Where the guide multiplies one published figure by another, for example a price per kW by a system size, it says "our arithmetic". Figures were last checked on 3 November 2026; when a source changes, the page is updated and re-dated.
The checks we point readers to
Because the guide recommends no firm, it shows readers how to check one themselves: MCS certification for solar PV, membership of a consumer code such as RECC or HIES, the company number on Companies House, and a written, itemised quote with every warranty listed, including whether the workmanship warranty is insurance-backed. Some firms are also registered with TrustMark. Asking a question here carries no obligation of any kind. The installer guide sets these out step by step.
What this guide is not
- It is not an installer and does not survey roofs, fit panels or give quotes.
- It is not Manchester City Council, GMCA or a government department, and it does not run any grant or loan scheme.
- It holds no trade accreditation and publishes no reviews or ratings of itself.
- It does not take phone calls; the form is the way to reach us.
For decisions about your own home, the council is the authority on planning, GMCA on the Warm Homes: Local Grant, and an MCS-certified installer's survey on what your roof can take. To start, try the roof yield explorer, read what solar costs in Manchester, or browse all the guides.
