Should you show Gas Safe & NICEIC on your website?
A homeowner ringing a trade they found online is taking a small gamble: they are about to let a stranger into their house, hand over a few hundred or a few thousand pounds, and hope it goes right. Everything on your website is either shrinking that gamble or leaving it where it was. Accreditations are one of the few things that shrink it in about a second, because a name like Gas Safe carries weight a customer already understands before they have read a word about you. There are roughly 130,000 businesses on the Gas Safe Register, and the reason it exists at all is that gas work by anyone not on it is illegal, so the public has been taught to look for it. That recognition is doing nothing for you if it is sitting on your van and nowhere on your site. The question is not really whether to show your registrations, it is how to show them so they actually win the job instead of just decorating the page.
Yes, show your Gas Safe, NICEIC, NAPIT or TrustMark registration on your website. Accreditations are among the strongest trust signals a trade site can carry, because customers are scanning for proof you are competent and legitimate. Always show the registration number, not just the logo, near the top of the page and in the footer. Show only the two or three that genuinely apply, keep them current, and pair them with real reviews and photos.
Do accreditations actually win more work?
A genuine accreditation such as Gas Safe or NICEIC is one of the most persuasive trust signals a trade website can show, because a customer hiring a stranger is looking for proof of competence, and a name they already recognise answers that faster than any amount of design.
Trust is the whole game on a trade site. A visitor who found you through a search has three unspoken questions: are you competent, are you legitimate, and are you going to make a mess of my house. An accreditation answers the first two in one glance, and it does it with borrowed authority, because the customer trusts the scheme even if they have never heard of you.
Why the recognition matters more than the badge
Gas Safe is the clearest case. It replaced the old CORGI scheme in 2009 and has been drummed into the public through years of "always use a Gas Safe registered engineer" messaging, so a homeowner sees that name and relaxes slightly. NICEIC does similar work for electrics. The badge itself is just an image; what you are actually cashing in is years of the scheme building recognition, and you get that for free simply by displaying it. Leaving it off the site throws away trust you have already earned by being registered.
It matters more for some trades than others
For gas and electrical work, accreditations carry heavy weight, because the risk of getting it wrong is obvious to any customer and the schemes are well known. For a painter or a gardener there is no single equivalent, so the trust load shifts onto reviews, photos and a tidy professional site instead. Show what genuinely applies to your trade; do not invent a badge to fill a gap. The broader picture of what convinces a customer is covered in how customers decide you are legit.
Which accreditations are worth showing
Show the two or three registrations customers actually recognise for your trade: Gas Safe for gas, NICEIC or NAPIT for electrics, TrustMark as the government-endorsed cross-trade scheme, and leave the obscure trade-body logos off, because unfamiliar badges add clutter rather than trust.
More logos is not more trust. Past the two or three names a homeowner knows, extra badges stop meaning anything, because the customer cannot tell a serious registration from a paid-for membership sticker. The job is to pick the ones that carry weight and show them well.
The ones customers recognise
For gas, it is the Gas Safe Register, which is a legal requirement rather than an optional extra. For electrics, it is NICEIC or NAPIT, the main competent-person schemes. Across most trades, TrustMark is the scheme backed by government and worth showing if you hold it. Those are the names with public recognition. Beyond them you are into logos the customer has never seen, which do little.
Registrations versus paid memberships
There is a difference between a registration you had to prove competence to hold, and a trade association you pay a subscription to join. Both can be worth showing, but the registration does more, because the customer senses it was earned. Be honest about which is which in your own head, and lead with the ones that were checked. A checkable registration number beats a membership logo every time.
How to show them so they build trust
Display the registration number in plain text alongside the logo, high on the homepage near your name and phone number and again in the footer, so a careful customer can verify it on the official register at the exact moment they are deciding whether to call.
A logo on its own is weak, because anyone can drop an image onto a page. What turns a badge into proof is the number next to it, sitting where the customer is already looking. Get the placement and the detail right and the same registration does far more work.
Show the number, not just the logo
Put your Gas Safe or NICEIC registration number in plain, readable text beside the badge. A cautious customer can type it into the official register and confirm you are current, and the fact that they can is itself reassuring, even to the ones who never bother. A logo with no number reads as decorative and is trivially easy to fake, so it earns much less than the two seconds it takes to add the digits.
Where on the page they pull weight
Near the top of the homepage, close to your business name and phone number, so a visitor sees them in the first few seconds while they are still deciding whether you are worth a call. Repeat them in the footer. Do not hide them on an About page most people never open. A trust signal only works if it is in front of the customer at the moment of doubt, which is high on the page. This sits inside the wider list of essentials in what a tradesman website should include.
The mistakes that make accreditations backfire
Accreditations backfire when the logo is expired or one you are not entitled to, which can breach both the scheme's rules and consumer protection law, or when the page is crammed with so many badges that none of them stands out and the site looks like it is overcompensating.
A trust signal can turn into a liability. The two ways it happens are showing something untrue, and showing too much. Both are easy to avoid once you know they are traps.
Displaying a logo you are not entitled to
Showing a registration you do not hold, or one that has lapsed, is worse than showing nothing. A customer who checks the register and finds you are not on it does not just move on, they now distrust everything else on the site. It can also fall foul of the scheme's own rules and of the Consumer Protection from Unfair Trading Regulations, which cover misleading claims. Only show what is genuine and current, and take a logo down the moment a registration expires.
Badge soup dilutes the whole page
Ten logos in a row does not read as ten times the trust; it reads as noise, and a careful buyer starts to wonder why you feel the need. It also buries the two that actually matter under eight that do not. Pick the recognised ones, give them room, and drop the rest. Restraint reads as confidence, and a confident-looking trade wins more work than a cluttered one.
Accreditations alone will not close the job
A registration proves you are competent and legitimate but says nothing about the quality of your work, so accreditations win the most when stacked with real job photos, genuine reviews and a fast, easy-to-contact site rather than shown on their own.
A badge is a tick in a box. It clears the "are they legit" question but leaves "are they any good" and "were other people happy" untouched. Those are answered by different signals, and the site that wins the enquiry is the one that carries all of them together.
Trust is a stack, not a single signal
Think of it as layers: the accreditation says you are qualified, the reviews say other people were glad they hired you, the photos say you do work like the job in front of the customer, and a fast site with an obvious phone number says you are easy to deal with. Strip any layer out and the site gets weaker. Together they turn a nervous browser into a booking. Whether that whole package is worth paying for, rather than piecing together yourself, is weighed up in is it worth paying for a trade website.
A worked example
Picture two Gas Safe engineers, both registered, both found in the same search. One site shows the Gas Safe number up top, three real photos of finished boilers, four reviews with first names and towns, and a tap-to-call button. The other shows a Gas Safe logo with no number and a stock photo. Same qualification, very different result: the first gets the call because it stacked its trust signals and the second leaned on one badge. That gap is the whole argument for building the site properly.
1. Is your registration number shown in plain text next to each badge, not just the logo?
2. Are the two or three that customers recognise near the top of the homepage, not buried on About?
3. Is every logo genuine and current, with no lapsed or borrowed badges?
See it done right on a free mockup
This is the sort of thing I build in by default. When I make you a free mockup of your actual business, your Gas Safe or NICEIC number goes where a customer looks first, next to real photos and reviews, on a site that loads fast and is easy to ring.
