Most gas engineers know they have to display their Gas Safe registration number somewhere. Far fewer know exactly where the Gas Safe logo on website pages is supposed to sit, or what the rules actually say about using it. Get it wrong and you're either burying proof of a legal requirement where nobody sees it, or using the logo in a way that breaches the terms of your registration.
This is a five-minute problem to fix properly. Here's how.
📍 Where the badge actually belongs
The short answer: header or footer, on every page, not just the homepage. Customers rarely land on your homepage first. They click through from Google straight to a service page ("boiler service Leeds") or land on a contact page from a Facebook ad. If your Gas Safe number only appears on the homepage, most visitors never see it.
Put the Gas Safe logo and registration number in the site footer, site-wide. That way it's present on every page automatically, without you having to remember to add it each time you publish a new one. Some businesses also repeat it near the top of the homepage or "about" page for visibility, which is fine, but the footer is the non-negotiable minimum.
The same logic applies to NICEIC. If you're both gas and electrically accredited, both logos sit together in the footer, usually alongside a Trustpilot or Google Reviews badge if you have one. Don't scatter accreditation logos across different pages inconsistently: customers (and Google, to a lesser extent) read consistency as a sign of a properly run business.
✅ What Gas Safe and NICEIC actually require
Gas Safe Register is not just a nice-to-have trust badge. It's the law: anyone carrying out gas work in the UK must be Gas Safe registered, and displaying your registration number is standard practice expected by customers who've been told (correctly) to check it before letting anyone near their boiler. Your registration is tied to you as an individual engineer, not your company as a whole, which matters if you employ other engineers: each one needs their own registration, and ideally the site should make clear whose registration covers which work if that's relevant to your business.
NICEIC is different: it's a voluntary accreditation scheme for electricians (there are others, like NAPIT), not a legal requirement, but customers increasingly ask for it because it signals a level of inspection and competence beyond the legal minimum. Both schemes have logo usage guidelines, generally requiring you to use the official artwork unaltered and not imply endorsement beyond what your registration actually covers. Check the current terms on the Gas Safe Register and NICEIC websites before adding artwork to your site: they update occasionally, and using outdated or altered logos can cause problems if a customer or a competitor ever queries it.
🔍 Why this matters more than it seems to
A customer deciding whether to call a gas engineer they've never used before is doing a fast trust check: is this a real business, is it legal, has someone reputable vouched for it. The Gas Safe logo does a lot of that work in half a second, before they've read a word of your copy. Bury it in a PDF certificate on a "credentials" page three clicks deep and you've thrown away free trust for no reason.
The same applies to NICEIC for electrical work, and to trade body membership (FMB, APHC and similar) if you hold it. None of these badges replace good copy or clear pricing, but they do the specific job of removing hesitation at the exact moment someone is deciding whether to pick up the phone.
🛠️ Getting the basics right without overthinking it
You don't need a design overhaul for this. A footer with your Gas Safe number, the official logo, and (if applicable) NICEIC or trade body badges, appearing on every page, covers the requirement and the trust signal in one go. If your current site was built years ago on a template and the footer only shows a copyright line, that's a genuinely quick fix rather than a rebuild.
At WebCheap, adding accreditation logos and registration numbers to a footer template is a small-batch change, typically covered within a £25 batch of small edits on an existing site, or built into the footer from the start on a new £395 base build. If your site needs a proper credentials section, that's a single extra page at £25.
The practical takeaway: check your own site right now. Open it on your phone, scroll to the footer of any page that isn't the homepage, and see whether your Gas Safe number and logo are actually there. If they're not, that's the first thing to fix, before worrying about anything else on the site.
