A UK small business should start with a complete Google Business Profile, then add WhatsApp or Messenger for enquiries, and only then pay for ads. Most UK adults are on WhatsApp and Facebook, so customers can reach you where they already are. Email and text have a consent rule that you need to get right first.
The UK has about 5.7 million private sector businesses, and 99.18% employ fewer than 50 people, according to the government's 2025 estimates. Most are one-person firms, so the advice below assumes an owner who does the marketing between jobs.

Estimates for illustration; actual numbers vary.
Where Are UK Customers Online?
Ofcom's Online Nation 2025 report is the main UK source. Its site returned an access error on 2026-10-25, so the figures below come from a news summary of the report and are secondary. In May 2025, 90% of UK online adults used WhatsApp, up from 87% in 2024, and Facebook with Messenger reached 93%.
TikTok reached 56% of online adults, with users aged 18 to 34 averaging 49 minutes a day. Instagram averaged 20 minutes a day; the summary gave no reach figure. UK adults spent an average of 4 hours 30 minutes online each day outside work.
For a local firm, the conclusion is practical. Messaging is a normal way to ask a question or book, so list a WhatsApp or Messenger link next to your phone number.
Should You Use Google Ads or Local SEO First?
Local SEO first, because a Business Profile is free and shows when someone searches nearby. Fill in your category, opening hours, services and photos, then ask for reviews. Our
Google Business Profile checklist has the steps.
Ads come second. Google says radius targeting needs a minimum of 1 km, and that "Presence or Interest" is the recommended default on Search. "Presence" fits when you only want people physically in the area.
UK click prices are not officially published. Agency blogs disagree widely, from about £0.60 to £3.65 depending on source and sector, and one review states there is no primary UK-wide survey. Use your own account data after the first month. See our
hair salon Google Ads guide for the UK for one niche.
How Do You Use WhatsApp for a Local Business?
Meta's WhatsApp Business Platform charges per delivered business-initiated message. It does not charge for messages customers send to you. Rates depend on the message category (marketing, utility, authentication) and the recipient's country, and the UK has its own rate card.
Each business number gets 1,000 free service messages a month, which do not roll over. Meta's page says charges for service messages beyond that tier start on October 1, 2026. The page does not list the sterling rates, so check Meta's rate file before you budget. The free WhatsApp Business app is a separate product; its limits were not checked here.
What Are the UK Rules for Email and Text Marketing?
The ICO's guidance on the Privacy and Electronic Communications Regulations says you need specific consent to send marketing emails or texts, such as a ticked opt-in box. A limited exception, the soft opt-in, covers your own customers who bought or discussed buying something similar, if you offered a simple opt-out when collecting their details and in every message.
It does not cover bought-in lists or people who never dealt with you. You must not hide your identity, and you must act on opt-outs. The rules also cover direct messages on social media. Sole traders and some partnerships count as individuals. Our
email and SMS guide for UK salons applies this to one trade.
What Does a First-Quarter Plan Look Like? A Worked Example
The numbers below are assumptions for a one-person service business, not UK benchmarks.
| Item | Assumption |
|---|
| Monthly marketing budget | £300 |
| Profile and reviews (month 1) | £0 |
| WhatsApp link and quick replies | £0 |
| Ads, month 2 onward | £250 |
| Cost per click (assumed) | £2.00 |
| Clicks per month | 125 |
| Share that enquire (assumed) | 5% |
| Enquiries | about 6 |
| Share that book (assumed) | 50% |
| Bookings | 3 |
| Cost per booking | about £83 |
If an average booking is worth less than £83 and customers rarely return, the ads lose money. If customers return often, they can pay back. Replace the assumed click cost and rates with your own numbers after 30 days.

FAQ
How many small businesses are there in the UK?
The 2025 estimates count 5,690,265 private sector businesses at the start of the year. Of these, 5,643,495 have fewer than 50 employees, and 4,272,535 have no employees.
Ofcom's data, via a news summary, shows the widest reach for Facebook with Messenger (93%) and WhatsApp (90%). The best one for you is where your customers ask questions.
How much does Google Ads cost in the UK?
There is no official UK average. Agency blogs give conflicting figures, so test with a small budget and read your own cost per click.
Can I text my existing customers about offers?
Often yes, under the soft opt-in, if they bought something similar from you and could opt out when you took their details and in every message. Otherwise you need specific consent.
Is WhatsApp free for businesses?
Customers messaging you is not charged on the Business Platform. Messages you start are charged by category, and sterling rates are in Meta's rate file.
