Can I say I'm the best in town on my website?

You can say it if nobody would take it literally, as long as it doesn't mislead. If people would read it as a fact, you need the evidence before it goes up. That's the UK advertising code, the CAP Code, which the Advertising Standards Authority rules on, and since 2011 it has applied to advertising on your own website. Which side "the best in town" falls on isn't something we can tell you. The ASA's own advice says that "will depend on the product or service advertised and the context in which the claim appears."

We're a hosting company, not lawyers, and not the ASA. Everything below that sounds like a rule is quoted from section 3 of the CAP Code and the ASA and CAP's AdviceOnline entries on own websites (dated 26 February 2026), "best" claims (24 April 2025), puffery and opinion (12 March 2026), "No. 1" claims and superlatives (both 11 April 2025) and awards and surveys (15 April 2025), all read on 14 October 2026. Each entry says of itself: "It does not constitute legal advice." Nothing below is a prediction of how the ASA would see your own wording.

Your website counts

The ASA's advice on own websites: "Since 2011 the CAP Code has applied to advertising on a company’s own website or in other non-paid-for space online under their control". It adds straight away that "this doesn’t mean that the Code covers everything online." What it covers is advertising — material "directly connected with the supply of goods, services, opportunities or gifts" — and it names sole traders alongside companies. The question it asks of a page is whether it "reasonably intends to ‘sell’ something." Your homepage and your service pages are there to get you work.

It's careful about what being covered means, too: "the fact that material is covered by the Code doesn’t necessarily mean it’s in breach, just that the rules apply to the content as they do for any other ad."

Two kinds of "best"

The two rules that matter here, in full:

Rule 3.2 — Obvious exaggerations ("puffery") and claims that the average consumer who sees the marketing communication is unlikely to take literally are allowed provided they do not materially mislead.

Rule 3.7 — Before distributing or submitting a marketing communication for publication, marketers must hold documentary evidence to prove claims that consumers are likely to regard as objective and that are capable of objective substantiation. The ASA may regard claims as misleading in the absence of adequate substantiation.

Puffery is the "best" nobody reads as a measurement, and the ASA's advice has an example of one. A pillowcase brand's "THE BEST SINCE 2004" "would be understood, in the context of the ad, as a subjective expression of Slipsilk’s opinion about their product and was therefore not capable of objective substantiation" (Slip Enterprises Pty Ltd t/a Slipsilk, 11 March 2020). For claims like that: "Marketers are not expected to hold documentary evidence to prove claims which will not be regarded by consumers as objective, or capable of objective substantiation."

The catch is who decides which kind yours is. "The ASA will assess a consumer’s likely interpretation of a claim, rather than the marketer’s intention." What you meant doesn't settle it. What a customer would take it to mean does.

And puffery has its own condition: it mustn't materially mislead. The puffery entry describes a 2005 complaint about "the ultimate broadband experience". The ASA accepted that was the advertiser's opinion, and upheld the complaint anyway, because "the incidence of severe customer dissatisfaction with the service was enough to make the claim inherently misleading" (Bulldog Communications Ltd, 2 March 2005).

When "best" turns into a fact

Saying what you're best at changes the claim: "If the criterion for the “best” claim is stated, and that criterion is objective, the claim will be considered objective too."

The advice's 2025 example is a phone deal. Three advertised "The UK's Best Value Unlimited iPhone deal" in ads with a strong emphasis on price, and the ASA decided that "consumers would likely interpret the claim to mean that Three Mobile's unlimited iPhone deal was cheaper than any of its competitors' unlimited iPhone deals" (Hutchison 3G UK Ltd t/a Three Mobile, 2 April 2025). "Best value" was read as "cheapest".

A plain "best", with nothing after it, is a comparison too: "Generally, unqualified “best” claims will be viewed as comparisons with all of an advertiser’s competitors."

That's what makes the evidence hard for a small business. "To substantiate superlative, top parity or “best” claims, advertisers are likely to be required to hold evidence which relates to their competitor’s product or service and which demonstrates how its own product/service compares." In other words, the evidence is likely to have to cover your competitors, not just you. The advice describes a claim to "The Best Alarm Technology on the Market": "Because the advertiser only had evidence relating to three competitors, and a relatively small number of features offered, this was not considered adequate to substantiate the claim" (Verisure Services (UK) Ltd, 1 June 2022).

No.1, leading, best-selling

The "No. 1" entry allows that a number-one claim could sometimes be read as puffery. Then: "Yet in practice, ‘number 1’ claims will almost always be regarded as objective comparisons." The superlatives entry says that, unless the nature of the product or the context gives them another meaning, or the meaning is ambiguous, "“no. 1”, “best-selling”, “leading” and other similar claims are generally treated as objective best-selling claims, particularly if they are unqualified." And: "Claims which will be interpreted as best-selling claims are likely to require evidence regarding market share, unit sales, or both."

Worth knowing if your homepage says "a leading provider". Our post on writing your own words already holds up "We are a leading provider of quality solutions." as what goes wrong at a keyboard, because it's stiff and generic. This is a second reason to cut it.

One of the advice's examples is a local business. "Derby's No.1 Award Winning Agent" "was considered ambiguous, and therefore had the potential to mislead, because it could have been understood to mean that the agency had won the largest number of awards compared to other agents in Derby, or that it had won at least one award and also had let the most properties." (IMS Lettings Ltd, 17 April 2013 — an old ruling, but the 2025 entry still cites it.) The entry's conclusion: "Marketing communications which do not make the basis of a ‘No.1’ claim clear are likely to be considered misleading."

Saying what the number one is based on changes what it means. The same entry says consumers would read "BOXT are also rated Britain’s number one heating company on Trustpilot" "as a factual statement about the advertiser’s Trustpilot rating" (BOXT Ltd, 15 July 2020). A factual statement still has to be true. But anyone can check it.

Award-winning, and "voted best"

The awards entry opens bluntly: "The ASA has investigated multiple comparative claims which were based on customer surveys, votes, or third-party awards. Many of these claims have been found to breach the CAP Code." Its rule of thumb: "Marketers should not rely on consumer perception data, or on the fact that they have received awards, to support claims for which they do not hold the relevant, objective substantiation."

Winning an award is a fact. The Derby case is what happens when an award and a superlative share a sentence: it could be read two different ways. Our suggestion, not the ASA's: name the award, the year and who gave it, and let that be the claim.

Calling it your opinion doesn't change it

If the plan was to put "in our opinion" in front of it, the puffery entry has already thought of that: "Marketers must not present objective claims as subjective opinion, to negate the need for supporting evidence under Rule 3.7. This could be done, for example, by putting quotation marks around an objective claim, prefixing an objective claim with “users thought” or making objective claims in testimonials." It also says the ASA has found "best" to be "objective in some contexts but subjective in others". That's why this post doesn't give you a list of safe phrases.

What to write instead

Our suggestion, not a rule: put the fact where the superlative was. "The best plumber in Bradford" asks people to take your word for it. "Gas Safe registered, twenty-two years in Bradford, most jobs booked within the week" gives them three things to check, and you can prove each one without knowing anything about every other plumber in Bradford.

Specifics are what a service page is made of anyway, and a registration number beside a trade body logo does more than any adjective. If you've won something, say what, when, and who gave it.

If you want a second opinion

CAP runs a Copy Advice service (page read 14 October 2026): "The CAP Copy Advice team offers pre-publication advice on non-broadcast advertising across all sectors." On timing: "Our standard response time is 3–5 working days, with paid options available for faster responses." And on what the advice is: "We give all advice in good faith, but it is not binding on you, CAP or the ASA."

Where beam sits in this

On a beam site, the words are whatever you ask the AI you use to write. Find every "best", "No.1" and "leading" on the site and show me each one is a sentence. So is replace the line at the top of the homepage with how long we've been trading and our registration number.
