Who is behind this website

Reion Miller
Gas Safe Registered Plumber & Heating Engineer
Gas Safe Register: 919881 10+ years experience South London & Surrey

R.W. Miller Plumbing & Heating is a sole-trader plumbing and heating business run by Reion Miller.

He has worked across South London and Surrey for over ten years, carrying out boiler repairs, installations, gas safety inspections, and general plumbing.

How content on this website is produced

The written content on this website — service descriptions, area pages, blog posts, and FAQs — is produced using a combination of AI-assisted drafting and editorial review by Reion Miller.

The process works as follows:

01
AI-assisted drafting Initial content is drafted using large language model (LLM) tools. Drafts are structured around real service and location data specific to the areas R.W. Miller covers.
02
Technical review by a qualified engineer Reion reviews all technical content — particularly anything relating to gas safety, boiler specifications, legal requirements for landlords, and diagnostic guidance — to ensure accuracy and compliance with current Gas Safe and industry standards.
03
Local knowledge verification Area-specific content is cross-referenced against Reion's direct experience working in those boroughs and postcodes. Claims about property types, common faults, and response coverage are verified against real operational knowledge.
04
Publication and ongoing review Content is published and reviewed periodically, particularly when Gas Safe regulations, pricing, or service areas change. Outdated content is updated or removed.

What we do not do

  • We do not publish AI-generated content without qualified review on any matter relating to gas safety, legal obligations, or technical recommendations.
  • We do not fabricate customer reviews. All reviews displayed on this website are from real customers and sourced from Google Business Profile.
  • We do not use AI to generate fake qualifications, Gas Safe numbers, or certifications. Reion's Gas Safe registration is publicly verifiable.
  • We do not exaggerate response times, coverage areas, or pricing in a way that cannot be honoured in practice.

Accuracy and corrections

While we make every effort to ensure the content on this website is accurate and current, gas regulations, pricing, and manufacturer guidance can change. If you believe any information on this site is inaccurate or misleading, please contact us:

We take corrections seriously and will review and update any content found to be inaccurate promptly.

By law, all gas engineers working on gas appliances in the UK must be Gas Safe registered. If an engineer cannot prove they are on the Gas Safe Register, do not allow them to carry out work. This applies to us as much as anyone else — always check before letting any engineer into your home.
