For a business that serves one town or postcode area, local Facebook groups and Nextdoor are usually the best place to start, because the people in them are already asking neighbours who to hire.
We cannot show you a head-to-head test in which these channels beat Instagram, and we have not found one published. The case rests on how people use them, and on the size of the audiences. This guide sets out both, then a 30-day plan.
It sits within our wider guide to hiring a social media marketing agency in the UK.
Why local groups suit local buyers
A local group puts you in front of people who live near you and who are already asking for a plumber, a dentist, a cake maker or a cleaner. A brand feed on Instagram puts you in front of whoever the algorithm chooses, anywhere.
Reach matters less than relevance for a business with a service area. A post seen by 400 people within five miles is worth more than one seen by 40,000 who cannot book you.
The other advantage is trust. A recommendation from a neighbour in a group carries more weight than an advert, and a business that answers questions helpfully builds a name over time.
How big the audiences are
Facebook remains one of the most widely used platforms in the UK. Ofcom's Online Nation 2025 report, published in December 2025, found that Facebook and Messenger reach 93% of UK adults. Ofcom's analysis of how the UK goes online has the full figures. Ofcom does not report a separate figure for Instagram in that piece, so we cannot compare them directly.
Nextdoor says more than 10 million people in the UK use it, around one in four adults, and more than 500,000 UK businesses have set up a business page. Those are the company's own figures from September 2024, so treat them as a claim from the platform. The Nextdoor announcement has the detail.
An earlier independent view comes from the University of Aberdeen Business School, which described Nextdoor in 2021 as having entered the UK in 2016, verifying members through device location and a phone number tied to a registered postcode. The Aberdeen piece notes that residents use it for lost pets, scam warnings and recommendations, and that the feed is often dominated by minor local complaints.
What people ask for in local groups
People ask for tradespeople, childcare, dentists, takeaway recommendations, second-hand items and help with a problem. The commonest pattern is a question, followed by a string of replies from neighbours.
That makes the business that appears in the replies, with a useful answer and a name, the one that gets the work.
It also means you win by being the person who answers well. A business that only posts adverts is treated as noise, and in many groups it is removed.
Why Instagram is a harder start
In our view Instagram is the harder place to start for a service business, though it can work well for businesses with a visual product, such as a florist, a salon or a bakery. It struggles for businesses with a service area, because nothing ties a viewer to your location unless you work at it with geotags, local hashtags and paid targeting.
It also takes longer. You have to build an audience before anyone sees you, and the people who follow you may not live near you.
We do not say skip Instagram. We say it should come after the groups for a service business, and in step with them for a visual one.
What reviews say about social channels
Local buyers check reviews, and some then check your social profiles. BrightLocal's 2026 consumer survey, which covered 1,002 US adults, found 97% read online reviews for local businesses and 24% of those who read a positive review then visit the business's social channels. Because the sample is American, treat it as a guide, not a UK figure.
The same survey found 74% care only about reviews from the last three months. So a steady trickle of recent reviews matters more than an old pile, and our guide to social proof that works covers how to collect them lawfully.
A 30-day plan for local social media
Run this in four weeks, with about 20 minutes a day.
Week 1: find and join the right groups
Search Facebook for your town, your neighbourhood and your trade. Join five to eight groups where people ask for recommendations or advice. Then read each group's rules before you post anything.
Look at who admins the group. A short, polite message to the admin asking what is allowed for local businesses prevents most bans.
Claim your Nextdoor business page if it exists for your area. A UK trades platform, Trade2Base, advises joining five to ten relevant groups and warns that group admins ban promotional spam, and that damages your name publicly. That matches what we would expect.
Week 2: answer questions
Reply helpfully to questions that fall within your trade. Give a real answer, with a figure or a step, and leave out your phone number unless someone asks.
Aim for three useful replies a day. They are the foundation: people begin to recognise your name.
Week 3: post once, with permission
With the admin's agreement, post one useful item, such as a seasonal checklist, a short answer to a common question or a photo of completed work with the customer's permission.
Keep it short and specific. Say where you work, and invite questions in the comments.
Week 4: ask for recommendations the right way
Ask three or four satisfied customers whether they would be happy to mention you if someone asks for a recommendation. Do not script it, do not offer a reward and do not post as a customer yourself.
The Digital Markets, Competition and Consumers Act 2024 bans fake and misleading reviews, with fines of up to 10% of global turnover, according to Lewis Silkin's guide to the law. Staff, friends and paid accounts posing as customers carry real risk.
Handling criticism in a public group
Sooner or later someone will complain about you in a group, and the whole neighbourhood will watch your reply. Reply once, politely, within a day, and move the details to a private message.
Say sorry for the experience without arguing the facts in public. Offer a specific next step, such as a call back by a named person. Then stop.
Readers judge the tone far more than the dispute. A calm answer to a bad review often does your name more good than ten glowing ones, because it shows how you behave when something goes wrong.
Never ask staff or friends to defend you in the thread. It is easy to spot, and with the review rules above it carries legal risk.
When local groups are not the right place
Local groups suit businesses that travel to customers or serve people who come to them. They suit a plumber, a clinic, a cafe or a tutor.
They do not suit a business that sells nationally online. If your customers are spread across the country, the groups will bring you little, and you should look at paid social or LinkedIn instead. Our guide to paid social against organic for B2B covers the second case.
They also do not suit a business with no capacity. If you cannot take on more work this month, hold off, because a rush of enquiries you cannot meet creates the kind of complaint that travels around a neighbourhood.
What to post once you are established
After a month, add a simple rhythm: one useful post in the groups a week, a few helpful replies a day and one post on your own page.
Use material from real jobs and real questions. Why most agency social content is invisible shows what to avoid.
Retailers and ecommerce brands with a local presence can add opening-hours changes, local delivery slots and collection options. These are practical items that groups welcome.
Special care for healthcare businesses
Healthcare is more sensitive. A dental practice or clinic has patient confidentiality duties and advertising rules about claims and before-and-after images.
Answer general questions in general terms. Do not discuss an individual's treatment in a public group, and do not name a patient even when they have posted publicly.
Check your regulator's current advertising guidance before you post, and decide who signs off wording.
How to measure local social media
Ask every new enquiry how they heard of you. Add "a local Facebook group" and "Nextdoor" as options on your form, and keep a tally in a spreadsheet.
Count recommendations that appear in groups without your prompting. They are the best sign that the work is paying off.
After 60 days, compare enquiries from groups against your other sources. If the groups produce more per hour of effort, put more time there.
