Two ways we grow trade businesses

Why trades marketing goes wrong

Why most tradesmen’s marketing wastes money.

Trade businesses rarely lack demand. They lose it through poor targeting, slow follow-up and leads they can never win.

01

Paying for the wrong areas

Ads shown across a whole region pay for clicks from places you would never travel to. Postcode targeting fixes it.

02

Shared leads and price wars

Lead sites sell the same enquiry to several firms. You end up racing to the cheapest quote instead of winning on quality.

03

Slow follow-up

A homeowner who waits a day for a reply has usually booked someone else. Fast calls, texts and email follow-up win more of the jobs you pay for.

The trades market

A crowded market where the best-marketed firms win the work.

There are hundreds of thousands of construction and trade businesses in the UK. Homeowners and contractors choose from the ones they can find and trust.

Why one retainer

One marketing team versus lead sites and freelancers.

Most trade businesses rely on lead sites, a nephew’s website and the odd ad. Here is what a joined-up retainer changes.

Questions

Trades marketing: frequently asked questions

What is the best marketing for tradesmen?

For most trade businesses the strongest mix is a fast website built for enquiries, Google Business Profile and local SEO for map results, Google Ads for urgent and high-value jobs, and Meta ads for planned projects such as extensions, kitchens and solar. Reviews and quick follow-up then turn enquiries into booked work.

How do you get better quality leads for builders and installers?

We target by postcode so you only pay for areas you cover, qualify enquiries with smarter forms, and exclude jobs you do not want. We then track which leads become quotes and which quotes become jobs, and move budget towards the work that pays.

Do you do marketing for plumbers and heating engineers?

Yes. Heating and plumbing is one of the trades we market for, and one of our Google reviews comes from a heating and plumbing company. We plan around seasonal peaks such as boiler breakdowns in winter, with call-led campaigns and schedules matched to when you can answer.

Is buying leads from lead sites better than running my own marketing?

Shared lead sites sell the same enquiry to several firms, so you compete on price from the first call. Your own marketing builds a brand, reviews and enquiries that come to you alone, and the cost per job usually falls as it matures.

Do you work with construction contractors and trade suppliers?

Yes. For contractors we focus on tenders, case studies and B2B lead generation. For trade suppliers and merchants we run ecommerce marketing, with Shopping campaigns, product SEO and email flows for trade accounts. We can also run Google and LinkedIn campaigns aimed at main contractors and developers.

How much does trades marketing cost?

One retained monthly fee pays for your website, SEO, ads, email follow-up and creative. What it costs depends on the services, areas and channels you want covered. Google and Meta ad spend is paid to them directly, and a free lead audit ends with a fixed quote.

Am I tied into a long contract?

No. Trade clients are on rolling monthly terms, so you can stop at the end of any month. In month one we agree targets for enquiries, cost per lead and jobs won, and every report after that shows how the business is tracking against them.
