Editorial policy
The standards used to research, write, check and update this site.
Our published recommendations are based on verifiable product specifications, authoritative guidance and our own comparison of practical trade-offs. Commercial relationships do not determine rankings.
Accuracy and updates
Important factual claims should be traceable to a saved source. Pages display their latest substantive update date. Corrections are made when reliable new evidence changes the answer.
Product recommendations
We explain why a product fits a particular need and include meaningful limitations. Where a feature matters, we distinguish a documented specification from our judgement about its likely usefulness. Our buying guides compare the same decision factors across models rather than treating a longer feature list as automatically better.
Common questions
Frequently asked questions
How are products chosen for a buying guide?
We compare products against the page's intended user, UK ground conditions, relevant specifications, limitations and overall practicality. A shortlist is not based on retailer commission alone.
How are errors and outdated details handled?
Material corrections are reviewed against reliable sources and updated when confirmed. Readers and manufacturers can submit evidence through the contact page, but editorial conclusions remain independent.
Does sponsored access guarantee positive coverage?
No. Samples, access or commercial contact do not guarantee inclusion, wording or ranking. Any relevant relationship should be disclosed where it could help readers judge the coverage.
