Editorial and evidence policy
This page explains how we write and check our guides. We put official sources first. We also tell you when a page was last reviewed.
Evidence before certainty
Funding rules change often. Budgets, limits and who can apply may all shift without warning. For that reason, our guides describe how a scheme works in general and link to the official page for current figures.
We do not present our summary as the final word. The public body that runs each scheme makes the decision, so we always send you there to confirm.
How we pick sources
We rank our sources in a fixed order. This keeps official facts ahead of opinion and sales material.
- GOV.UK and devolved government scheme pages. These decide eligibility and current rules.
- Regulator and consumer body guidance, such as the Competition and Markets Authority and the Renewable Energy Consumer Code.
- Other official UK energy reports, used for background only.
- Company material, used only as a labelled example. We never rely on it alone for a funding claim.
Every guide lists the sources we used, so you can check our work. You can also see them together on the sources page.
Dates and reviews
Each guide shows the date we last checked it against the official sources. We change that date only after a real review or a real edit. When a fact depends on timing, we say so in the text, for example by writing "as of October 2026".
Since rules change, we say so if we cannot confirm whether a scheme is open. In that case we ask you to check the official page, and we do not guess.
Corrections
We fix mistakes in place because readers rely on current facts. A correction that changes the meaning of a page gets priority. To report a problem, use the complaints and corrections page or the contact page.
Use of AI tools
Our team may use software to help organise research and draft text. However, a tool never publishes a page by itself. A person checks each claim against the cited source before the page goes live.
We do not invent quotes, case studies, people or statistics. We also avoid duplicate pages, and we write each page title and summary to match what the page really says.
Keeping advice apart from sales
We order our guides by what readers need, not by what earns money, because trust matters more. The funding checker and the quote request are separate on purpose. Because of this, using the checker never starts an enquiry.
If we ever add a paid placement or referral deal, we will label it clearly. No installer can buy an endorsement from us. You can read more about who we are on the about page.
