How we research, write and update our guides
The point of the Evova knowledge hub is simple: give you the same answer a well-informed friend in the trade would, with the sources to back it up. This page explains how that content gets made and kept honest.
Where our information comes from
Guides are researched from primary sources: government guidance on GOV.UK for grants and regulations, Ofgem and supplier tariff pages for energy costs, manufacturer documentation for charger specifications, and the official registers (like Companies House) for anything about businesses. Where a guide states a figure that can change — a grant amount, a typical installation price, a tariff rate — we link to where it came from and date it, so you can check it's still true.
We're a directory and knowledge hub, not electricians. We don't carry out, design or survey electrical work, so our guides explain your options and what to expect — the specifics of your home always come from the qualified installer who quotes for the job.
How guides are produced
We research and draft with the help of AI tools, and we're upfront about that. What makes the content trustworthy isn't how the first draft gets written — it's the checking. Every guide goes through a fact-verification pass against primary sources before it's published, and pieces covering money or safety (grants, costs, electrical work) get a human editorial review on top. Nothing is copied from other websites, and nothing is published that we can't stand behind.
How guides stay accurate
Every guide displays its published or last-updated date. Content that depends on figures that move — grant schemes, typical costs, energy tariffs — is reviewed quarterly, and immediately after the government's annual April changes to grant schemes. Our grants hub shows a "last checked" date against every scheme for the same reason.
How we make money (and why it doesn't bend the content)
Evova is free for consumers. We earn from services to installers, such as verified memberships and passing on quote requests. We don't run display ads, we don't take commission on charger sales, and manufacturers can't pay for placement in our comparisons. Where a listing or link is commercial — like a Featured installer — it's labelled. You can read more about how listings work on our verification methodology page.
Corrections
If you spot something wrong or out of date, email hello@evova.uk. We review correction requests promptly, fix what's wrong, and update the guide's date so the change is visible.
The rules we write by
Primary sources first
Grant amounts, deadlines and eligibility rules come from GOV.UK and the scheme operators, not from other blogs. Where a figure matters, we link the source and show when we last checked it.
Dated, and kept current
Every guide shows when it was published or last updated. Grant, cost and tariff figures are reviewed on a quarterly cycle — and always after the annual April rule changes.
No invented numbers
If we quote a price range or a statistic, it's traceable to a named source or to our own directory and enquiry data, published with its methodology. If we don't know, we say so.
Independent
We don't run display advertising and we don't earn commission selling chargers. Evova makes money from services to installers, and that never changes what a guide says.
