Marketing for construction companies: what works for UK builders

Marketing for construction companies comes down to being the firm a customer can find, check and trust before they pick up the phone. For most UK building firms that means three things first: a website that shows finished jobs, a Google Business Profile with reviews arriving steadily, and pages that rank for the job types and towns you want. Then the things only a builder can do: a board on every site, a van people remember, a trade body badge and, for bigger firms, public tenders.

We build websites and do SEO for trades, so we have an interest in the first three. The rest of this guide covers what we do not sell, with the costs and the rules taken from their sources.

Start with what customers check

A customer who hears your name, from a friend or from a board outside a job, will often look you up before they ring. So the first job is making sure what they find is yours, and is good.

• A website that shows the work. Finished jobs with photos, the work you want more of, the towns you cover, your accreditations and a phone number that works one-handed. Our guide to what a tradesman website should include has the checklist, and our websites for construction companies page shows how we build them.
• A Google Business Profile that is complete. Google says local results are "mainly based on relevance, distance and popularity", and that "more reviews and positive ratings can help your business's local ranking". If yours is not appearing, our guide on a Google Business Profile not showing finds the cause.
• Reviews that keep arriving. Building jobs run for weeks or months, so there are natural moments to ask: practical completion, snagging sign-off and final payment. Ask every customer the same way. Google's policy bans offering anything in exchange for a review and asking only the happy ones, and since 6 April 2025 UK law bans fake reviews and reviews that hide an incentive. Our guide on how to get Google reviews has the wording.

Get found for the jobs and towns you want

The searches worth winning name the work. In the UK, "builders near me" is searched about 18,100 times a month, "loft conversion" 12,100, "house extension" 5,400 and "extension builders" 590 (DataForSEO, November 2026). Someone typing "loft conversion" plus a town has decided what they want and is choosing who does it.

To be found for those, you need a page for each kind of work you want more of, with your own photos and the towns you genuinely price in, and a profile whose services list matches. That ongoing work is what SEO for builders is. It is slower than buying a lead, and it does not stop when a subscription does. What it costs a month, and what each price buys, is in our guide to how much SEO costs.

Site boards and the van

These are the two adverts most builders already have, and the rules on both are kinder than people think. The government's guide for advertisers covers England; the rest of the UK has its own rules.

A board on every site. A firm carrying out building work may display its own board at the site without applying for consent, provided it is no bigger than 2 square metres, and only while the work is going on. If every firm on the job shares one board, it can be 2 square metres plus 0.4 for each extra firm named. The board must not be lit, its letters can be no taller than 0.75 metres and its top no higher than 4.6 metres, with lower limits of 0.3 and 3.6 metres in an Area of Special Control. Like every outdoor advert it needs the site owner's permission, which on a domestic job means your client. Ask at the start, and take it down when you finish.

Make the board earn its place: your name, the phone number, the web address and the kind of work, so a neighbour who walks past every day knows who to ring about their own extension.

The van. The same guide lists adverts on a vehicle that is normally moving among those outside the planning authority's direct control. So the van can carry your name, number, web address and trade body badge, as long as it is used as a van and not parked up as a billboard.

Trade bodies and directories

A trade body badge is something a careful customer can check, and some bodies list members where homeowners search.

The Federation of Master Builders vets members and inspects their work before they join. Its fee, on its own join page: £62.69 plus VAT a month, plus an inspection fee of £14.85 plus VAT a month in the first year. That is £930.48 plus VAT for the first year and £752.28 plus VAT a year after (our arithmetic). You need 12 months' trading history, joining takes two to three weeks, and if you pay monthly you can leave at any time. Members get a profile on the FMB website, which the FMB says gets 20,000+ consumer visits a month, and it is a scheme provider for TrustMark, so members can register with TrustMark through it.

Other schemes and directories charge in different ways. Which? Trusted Traders and the council-run Trading Standards schemes are endorsements, compared in our guide to whether Which? Trusted Traders is worth it. MyBuilder charges when a customer shortlists you, which can suit builders quoting bigger jobs: see whether MyBuilder is worth it. The wider comparison, with prices, is in Checkatrade alternatives.

Public sector and commercial work

Public bodies publish their contract opportunities on the government's own services.

• England: Contracts Finder lists contracts worth over £12,000 including VAT with the government and its agencies, and Find a Tender carries high value contracts, usually above £139,688 including VAT. GOV.UK says you can search and apply on Contracts Finder without an account.
• Scotland, Wales and Northern Ireland: Public Contracts Scotland, Sell2Wales, and eSourcing NI and eTendersNI.

Paid platforms such as Constructionline, Glenigan and Barbour ABI sell earlier notice of projects and tenders. Our guide to construction leads compares what they charge and who they suit.

Referrals and the people around your jobs

Referrals cost nothing per job, and they are worth looking after on purpose:

• Past clients. A short message a few months after a job, a request for a review at handover and a card for the neighbours who watched the work go up.
• Architects, surveyors and merchants. They see projects before builders are chosen. Keep them in touch with jobs you have finished, and link to each other where you can. Google says how many websites link to your business is part of how it ranks local results.
• Other trades. Electricians, plumbers and roofers on your jobs get asked to recommend a builder. Pass work their way, and ask them to do the same.

Paid search and directories to fill gaps

When the diary has a hole in it next month, paid channels are the quick fix. Google search ads charge per click; Google's Local Services Ads charge per lead, and our guide to Local Services Ads for UK trades explains how the price is set. Directories and lead sites fill gaps too, but a lead is often sold to several firms, and the reviews you collect there stay on their site. Use them alongside the website and profile, and cut them back as your own enquiries grow.

When to market a building firm

Plan for January. Searches for "builders near me" in the UK were highest in January 2026, at 27,100, against 12,100 in December 2025, and "loft conversion" peaked in January 2026 at 18,100 (Google Ads data via DataForSEO). Searches for "marketing for construction companies" follow the same pattern, at 260 to 320 a month from January to March 2026.

So the work that takes months, the pages, the profile and the reviews, needs doing in the autumn, ready for the people who start looking after Christmas.

Track where every job comes from

Ask every enquiry how they found you, write it down, and once a quarter divide what each channel cost by the jobs it won. It is the only way to know whether the board, the badge, the directory or the website is earning its keep. The free lead cost calculator does the sum for paid channels side by side.
