Why Reviews Are the Highest-ROI Marketing Lever for Drainage Engineers
Compare reviews to Google Ads, leaflets, vans, or Checkatrade fees and the maths is not close. Drainage is an emergency service. When a drain blocks, customers Google and call fast. Your reviews need to convey rapid response, fair pricing, and problem solved. That's what gets you picked over the national chains. Reviews are owned, permanent, and compound — paid advertising is rented and stops working the day you stop paying.
"drainage engineer near me"
Google shows the top three results for this search based heavily on review count, rating, and recency. Most clicks go to those three.
Trust signal
For a drainage business, reviews are the first social proof potential customers see — long before they ever talk to you.
Permanent asset
Unlike Checkatrade, Google reviews are free, owned by you, and don't disappear when you stop paying.
What's Holding Most Drainage Engineers Back From Growing
It's almost never the work. It's almost always one of the four bottlenecks below — and all of them sit upstream of reviews, which is why fixing reviews has such an outsized effect on growth.
Nobody wants to think about drains — let alone review the experience
Emergency unblocking is urgent but forgettable once fixed
Drain work is unpleasant — customers want to forget it happened
You compete with Dyno-Rod and national chains
Top-ranking drainage engineers typically have 30-60 Google reviews.

Questions From Growing Businesses
How much extra revenue can a drainage business make from reviews?+
A typical drainage engineer climbing from outside the map pack into the top three sees enquiry volume roughly double. At £100 - £3,000 per job, the maths compounds fast — and unlike paid ads, it doesn't stop when you stop paying.
How long does it take to see growth?+
Local ranking lift starts in 4-8 weeks of consistent review collection. The compounding effect — where reviews bring more customers who leave more reviews — kicks in around month 3-4.
What's the cheapest way to grow a drainage business?+
Reviews. Per pound spent, nothing else comes close — and the asset you build is permanent, unlike ads or platform leads.
Should I still pay for ads or leaflets?+
Sometimes — but only after your review profile is doing its job. Paid traffic to a 12-review profile converts terribly. Paid traffic to a 60-review profile flies.
Compound growth, one review at a time.
£100 - £3,000 per job × the extra customers that find you through better rankings = the only marketing channel that pays back forever.
