Editorial Standards

Last reviewed 27 April 2026

This is our public editorial policy. It describes how content on BoilerFaultCodes.com is produced, reviewed, corrected, and kept up to date. If you ever find an error or have a question about how a piece of content was produced, you can reference this policy directly.

1. Who writes the content

Fault code reference content is produced by the BoilerFaultCodes Editorial Team and reviewed before publication. The team comprises editors with experience in technical writing for the UK heating industry. Where a named technical reviewer (Gas Safe registered) signs off on a piece of content, their name and registration number are displayed on the page.

Guides on home heating, repairs and buying advice are written by the same team and follow the same review process.

2. How a fault code page is built

1. The raw fault code is extracted from the official manufacturer service or installation manual for the affected model. We hold copies of the source manuals.
2. The technical description in the manual is reproduced verbatim or paraphrased without altering meaning.
3. A plain-English summary is written for the homeowner.
4. Severity (Emergency / High / Medium / Low) is assigned based on safety implications and impact on heating/hot water.
5. A DIY-safe flag is set conservatively — only codes that homeowners can resolve without touching gas, electrics or sealed components.
6. Repair cost ranges are estimated using current UK trade rates (parts + labour) and are reviewed annually.
7. The page is reviewed by an editor before publication.

3. Sourcing

Every fault code on the site is sourced from one of the following:

• The manufacturer's official service or installation manual for the specific model
• The manufacturer's published fault code reference for a product family, where service manuals are unavailable
• Cross-referenced data from inherited series codes (clearly marked) — e.g. where a model variant inherits the fault code set from its parent series

We do not source fault code information from forums, anonymous trade websites, or other secondary sources. Where a model has no manufacturer documentation we can verify, we mark the model as a stub and do not publish unverified codes.

Read the full sourcing methodology at How We Source Fault Codes.

4. Safety

We follow the UK regulatory position: gas work must be carried out by a Gas Safe registered engineer. We never publish DIY instructions for any task that involves gas, the sealed combustion circuit, the flue, the gas valve, or burner/heat-exchanger components — regardless of whether a homeowner could physically attempt them.

Codes flagged DIY-safe are limited to issues such as low pressure top-ups, condensate-pipe defrosting, filter cleans, time/programmer configuration, and reset procedures.

5. Updates and review

Every fault code page carries a "Last reviewed" date. We re-review content when:

• A manufacturer issues an updated service manual
• A user reports an error
• Annual editorial review (cost ranges, safety guidance)

Substantive changes update the "Last reviewed" date and the dateModified field in the page's structured data. Minor corrections (typos, formatting) do not bump the review date.

6. Corrections policy

If you spot an error — whether factual, technical or safety-related — please email hello@boilerfaultcodes.com with the page URL and a description of the issue.

Verified corrections are made promptly. For safety-related corrections, the page is updated within 24 hours of verification.

7. Editorial independence

We take affiliate revenue from boiler cover providers and replacement quote services. Editorial content is produced independently of any commercial relationship. A code's DIY-safe flag, severity rating, repair cost estimate or recommended remedy is never adjusted to benefit a commercial partner.

We do not accept paid placement of fault code information. We do not accept payment to remove or downgrade fault code reports.
