Lead Generation for Builders
A shared lead on a £19,450 job is a price war you entered voluntarily
What happens when four builders buy the same enquiry
A single storey extension is £19,450. A dormer loft conversion, £17,200. A garden room, £12,850. A garage conversion, £5,900. An internal wall removal with an RSJ, £2,750.
The lead platforms will sell you an extension enquiry. Depending on the platform and the job value, that costs somewhere between about £15 and £70, and the same enquiry is typically sold to three or four other builders at the same moment.
Consider what that produces. Four firms ring the same homeowner within an hour. All four visit. All four quote. The homeowner, who had no basis for comparison before, now has one — price — and uses it, because nothing else in the process gave them anything else to compare on.
You have paid for the privilege of entering an auction on a job worth £19,450, against three competitors you did not choose, in a format that systematically favours whoever is cheapest or most desperate.
Some builders make it work by being fast, disciplined and ruthless about qualifying. Most quietly spend a few thousand pounds a year on it, win a modest share at compressed margins, and cannot say whether they are ahead.
The alternative is not more marketing. It is a completely different kind of lead, and for a builder it is unusually accessible.
The leads that arrive pre-qualified and unshared
Architects and architectural technologists. They meet the customer months before you would, they shape the brief, and they are asked who should build it. A single architect specifying two jobs a year is worth roughly £38,900 at your average value, arrives without competition, and comes with drawings that make quoting faster and more accurate.
Structural engineers. Same dynamic, slightly later in the process, and a smaller group in most towns.
Estate agents. They are asked constantly whether a loft could be converted, and they benefit directly from work that adds value to a property they may sell.
Planning consultants, who deal with exactly the households about to spend money.
Adjacent trades. Kitchen and bathroom firms, window companies and landscapers all meet people mid-project who need structural work.
Past customers as referrers. They will not build again, but they are asked about you at the school gate, and the month after a build finishes is when that happens most.
None of those are bought. All of them are cultivated, and the total group in most towns is between forty and a hundred and twenty names.
The ratio
An extension is £19,450. Our Booked package is £99 a month — £1,188 a year. One extension covers more than sixteen years.
Set that against platform spend. Three thousand pounds a year on shared leads, at a low conversion rate and compressed margins, is a working assumption for a lot of builders. The same effort spent on forty professional relationships produces unshared enquiries at a better price and with the drawings already done.
What we’d actually build
The referrer list, properly — every architect, engineer, agent and consultant within your working radius, with a note of who has ever sent you anything.
A reason to be on their radar. A quarterly project note about one job, written so it can be forwarded to a client.
A capability sheet for professionals, covering the kind of work you take, your typical programme and how you handle variations — which is what an architect actually needs to know.
A referral position for past clients, raised at handover when the goodwill is highest.
A qualification filter on any bought leads you do keep, so the money is spent on the job types you win rather than on everything the platform sends.
Source tracking, so within a year you know what each channel actually produced rather than what it felt like.
What good looks like at twelve months
- A professional list of eighty to a hundred and fifty names, contacted quarterly
- At least two architects or engineers sending work regularly
- Enquiries arriving with drawings attached rather than with three competitors
- Platform spend either justified by tracked returns or reduced
- Every enquiry recorded against its source, so the argument stops being about opinion
The mistakes we see most
Buying shared leads without measuring. The spend is visible and the return is not, which is how it continues for years.
Approaching architects once and giving up. These relationships are built over quarters, not calls.
Nothing written for a professional audience. A site built entirely for homeowners gives an architect nothing to assess.
Never asking past clients for referrals. The month after completion is the best opportunity you get and it passes silently.
The first ninety days
Weeks 1–4. Source tracking turned on and the referrer list built, which together tell you where you actually stand.
Weeks 5–8. The professional capability material and the first quarterly project note.
Weeks 9–12. Referral asks built into handover, and a decision on platform spend based on three months of real numbers rather than impressions.
At ninety days the measure is whether any enquiry arrived through a professional who had never sent you one before. That is the channel that changes a builder’s year.
Where this lands in Gaffer
Enquiries record their source, which is the only way the platform-versus-referral argument gets settled with numbers instead of instinct.
Contacts can be marked as referrers rather than customers, so the professional list stays separate and its contribution is visible.
And because jobs hold the drawings, photographs and dates, the quarterly project note is assembled from work you have done rather than written from scratch.
What actually ends an architect relationship
Worth understanding before you start, because these relationships are slow to build and quick to lose, and the things that end them are not the things builders expect.
An architect recommending you is putting their own reputation into your hands. If the build goes badly, the client does not blame the builder they were introduced to — they blame the person who introduced them. That asymmetry explains almost everything about how architects behave towards contractors.
So the ending is rarely about workmanship. It is about the moments where you made them look bad.
Criticising the design in front of the client. Every builder has opinions about drawings. Voicing them to the homeowner, rather than to the architect privately, is the single fastest way to be removed from a list.
Going direct on the next one. Bypassing the architect on a job they introduced ends the relationship permanently and the story travels.
Pricing so high they look foolish for suggesting you. Being expensive is fine if the quote explains itself. Being unaccountably expensive on a job they specified reflects on their judgement.
Variations they hear about from the client. An architect administering a contract needs to know about changes before the homeowner rings them confused.
Going quiet mid-programme. They are answering to the client and cannot do it without information from you.
None of that is difficult. All of it is a matter of remembering who is exposed when things go wrong, and behaving accordingly. Builders who understand it hold these relationships for a decade, which is why one architect can be worth more than every advert ever placed.
Questions builders ask
Are lead platforms ever worth it? For smaller, well-defined jobs some builders make them pay. On a £19,450 extension shared four ways, the format works against you.
How long before architects send work? Two to four quarters realistically. It is slow and it compounds.
What do architects actually want? A builder who prices honestly, communicates and turns up when the drawings are ready. Show a job where you did all three.
Should I stop buying leads immediately? Measure first. Three months of tracked data makes the decision for you.
