How Much Should UK Trade Businesses Spend on Marketing? A Budget Guide (2026)

Ask most plumbers, electricians, or builders how much they spend on marketing and you'll get a rough number. Ask them what return they got on it, and you'll get a shrug. Marketing budget decisions in the trades are almost universally made on gut feel — a mate recommended Checkatrade, someone suggested Google Ads, a leaflet drop seemed like a good idea at the time. Without tracking, every pound spent is a guess.

This guide cuts through the noise. It covers what UK trade businesses actually spend, what the benchmarks suggest you should spend at different sizes, where that money tends to go, and — critically — how to stop spending on channels that aren't delivering.

Why Marketing Budget Is Guesswork for Most Tradespeople

The fundamental problem is a data vacuum. Most sole traders and small trade businesses have no reliable way to connect a specific marketing spend to a specific paid job. A homeowner finds you on Google, rings your number, you quote, they book — but did they find you through your Google Business Profile, a Google Ad, Checkatrade, or a friend's recommendation? Unless you actively ask and record it, you have no idea.

This means budgets get set based on what feels comfortable, what a competitor seems to be doing, or what a salesperson from a lead generation platform convinced you to spend. None of these are good reasons. The result: businesses keep renewing Checkatrade subscriptions because "it's probably working," keep running Google Ads because "we're showing up," and keep dropping leaflets because "we did get a call last time."

Proper budgeting starts with proper tracking. But even before you have perfect data, benchmarks can point you in the right direction.

Industry Benchmarks: What Should a Trade Business Spend?

For B2C service businesses generally, the accepted benchmark is 5–10% of revenue on marketing. Trade businesses tend to sit lower — typically 3–7% — because a significant chunk of work comes from word of mouth and repeat customers rather than paid channels. A well-established plumber who's been trading for 15 years in the same town might spend 2% and be fully booked. A new electrician trying to build a customer base from scratch might need to push toward 8–10% temporarily.

The percentage approach is useful as a sanity check, but absolute numbers are more practical for planning. Here's a realistic breakdown by business size:

These are realistic working budgets — not the minimum to survive, not the maximum you could theoretically spend. A solo tradesperson spending £2,000/year might put that entirely into a Checkatrade subscription and their Google Business Profile. A business turning over £500k might split £50k across Google Ads, SEO, a marketing agency retainer, vehicle signage across a fleet, and social media management.

Where Most Trade Businesses Spend Their Marketing Money

Here's a realistic breakdown of the main channels UK trade businesses use, what they cost, and the honest ROI reality of each.

The Tracking Problem: Where Most Budgets Go Wrong

Here's the uncomfortable truth: most trade businesses cannot tell you which £100 of marketing spend brought in which £1,000 of work. They might be able to point to Checkatrade as a source for a handful of jobs, or vaguely remember that Google Ads was running when bookings picked up in spring. But genuine channel-by-channel attribution — knowing that their Facebook Ads generated 12 enquiries, 4 quotes, and 2 paid jobs worth £3,200 in the last quarter — is almost non-existent.

Without that data, cutting a poor-performing channel feels risky ("what if it's actually bringing in work I can't see?") and doubling down on a strong channel is just optimistic guesswork. The businesses that grow their marketing efficiently are the ones that treat every pound as an investment they intend to measure.

How to Allocate Budget: Start, Track, Double Down

If you're starting from scratch, don't try to be everywhere at once. Pick two or three channels that make sense for your trade and service area, spend a realistic test budget (at least 90 days — long enough to get meaningful data), and measure what happens.

The allocation framework is simple:

1. Non-negotiable baseline: Google Business Profile (free — just invest the time), vehicle signage (one-off cost), and a functional website. These should be sorted before you spend a penny elsewhere.
2. Chosen test channels: Pick one or two paid channels suited to your stage. Early stage: Checkatrade or Google Ads. Established: Facebook Ads for awareness, SEO for long-term growth.
3. Track religiously: Every enquiry gets a source recorded. Every quote gets a source. Every paid job gets a source. After 90 days, look at which channels delivered the most paid jobs — not just enquiries.
4. Cut and concentrate: Drop anything that isn't delivering. Increase spend on what is. Repeat quarterly.

The Attribution Question: "How Did You Hear About Us?"

The simplest attribution method costs nothing: ask. Every time a new customer contacts you, your phone script should include "Just so I know, how did you find us?" Every quote form on your website should have a dropdown: Google search, Google ad, Checkatrade, Facebook, referral, leaflet, van, other.

This matters because the data you collect shapes every future budget decision. A tradesperson who knows that 40% of their paid jobs came from Google Business Profile reviews and 35% from word of mouth can be confident that investing in a call tracking system or Facebook Ads is a test — not a replacement for what's already working.

For more sophisticated tracking, dedicated phone numbers per channel (via services like CallRail or ResponseTap) let you see exactly which channel drove an inbound call. UTM links on digital ads tell Google Analytics exactly which ad sent a visitor who then filled in your quote form. These are worth setting up once you're spending serious money — say, £1,000+ per month — on any digital channel.

Seasonal Spending: When to Push Budget Harder

Most trade businesses have predictable seasonal patterns. Boiler engineers get emergency calls year-round but installation enquiries spike in autumn. Landscapers and driveway contractors see their busiest enquiry periods in spring. Bathroom and kitchen fitters often see January and September as strong enquiry months as homeowners finalise renovation plans.

Smart budget allocation front-loads spend in the period before peak demand — not during it. Homeowners who are planning spring work are making decisions in January and February. If your Google Ads budget is highest in March when demand is already there, you're competing harder for a saturated auction. Spend in January to get onto shortlists before competitors ramp up.

Similarly, in slow periods — typically July–August for indoor trades and November–December for outdoor ones — consider whether it's worth maintaining full marketing spend or temporarily redirecting budget to improve your website, collect more reviews, or prepare content for the peak season push.

When to Hire a Marketing Agency

There are clear signs you've outgrown DIY marketing:

• You're spending £1,000+/month on Google Ads without a clear view of what's converting
• You know you should be doing more but don't have the time or inclination to learn
• Your website hasn't been updated in years and you're losing leads to competitors with better online presence
• You have the budget to test properly but not the bandwidth to manage campaigns

A trade-focused marketing agency typically costs £500–£2,500/month depending on the scope of work. For that, you should expect: a properly managed Google Ads account with conversion tracking, monthly reporting on real metrics (not vanity metrics like impressions), ongoing SEO work, and clear communication about what's working.

Be wary of agencies that won't show you exactly what you're getting for your money. A good agency will welcome scrutiny. Ask for a specific cost-per-lead figure and a breakdown of which channels are generating which enquiries. If they can't answer that cleanly, look elsewhere.

How Trade2Base Tracks Exactly Which Marketing Brings In Paid Jobs

Most CRM and job management tools for trades record enquiries. Fewer track where those enquiries came from. Almost none connect the marketing source all the way through to a paid, completed job — which is the only number that actually matters for ROI.

Trade2Base is built around this problem. When a new enquiry comes in, you record the source — Google, Checkatrade, referral, Facebook ad, whatever. That source stays attached to the job record as it moves through quoting, acceptance, and payment. At the end of any period, you can see exactly how much revenue each marketing channel has generated, not just how many enquiries it sent you.

That means you can answer: "Did my Checkatrade subscription pay for itself this year?" with a real number, not a guess. "Is Google Ads actually profitable after ad spend?" — answered. "Which channel brings in the biggest jobs, not just the most jobs?" — visible at a glance.

When you can see that data clearly, cutting a £3,000/year Checkatrade subscription that delivered £4,000 of work becomes an easy call. Doubling down on Google Ads that returned £18,000 from a £4,000 spend becomes an obvious move. The decisions stop being guesswork and start being straightforward.
