Door-to-door canvassing vs digital prospecting: what wins in 2026

The "door-knocking vs digital" debate is the wrong debate. It's been the wrong debate for at least three years, and every conference panel that frames it as a choice has cost the industry instructions.

Both channels work. They work for different reasons, at different costs, and on different homeowners. The interesting question — the one branch managers should actually be asking — is which signal triggers which channel, and whether the cost per instruction makes the maths work for your patch.

The honest numbers

Let's get the unglamorous figures out of the way, based on what UK independent and corporate branches we've worked with are seeing in 2026:

• Cold door-knocking: roughly £150-£300 cost per instruction once you fully load negotiator time, branch overhead and conversion rates. A two-hour session with three negotiators that yields one valuation appointment and a 35% list rate is, depending on how you count car parks and coffees, around the middle of that range.
• Digital prospecting (paid social, retargeted portal-style valuation tools, Google search ads on "estate agent + postcode"): £40-£80 cost per instruction at decent click-through, but heavily dependent on the patch and the offer.
• Warm door-knock triggered by digital signal: £60-£120, because the door is pre-qualified and the conversion rate at the doorstep roughly doubles.
• Hand-written card on a signal-triggered address: under £20 per instruction when it works, but it's lumpy and unreliable on its own.

Notice what the cheapest two have in common. Neither of them is "digital" or "doors" in isolation. They're both signal-triggered.

Why the dichotomy is wrong

Digital prospecting is excellent at one thing: catching a homeowner at the exact moment they've decided to think about moving. The valuation widget, the retargeted ad, the search query — these all hook intent the moment it surfaces.

Door-knocking is excellent at a completely different thing: creating intent in a homeowner who wasn't actively thinking about moving but is now talking to a human about their loft, their commute and their daughter's school. No widget on earth can do that.

Digital catches the decided. Doors create the undecided. You need both, because every patch has a mix of both, and they aren't the same homeowners.

A branch that does only digital is throwing money at the small fraction of homeowners who happen to be Googling that month. A branch that does only doors is paying full price to knock on the 95% of addresses that aren't anywhere near a moving decision. The branches winning in 2026 are the ones that use digital to find the warm and doors to find the warmable.

What signal triggers what

This is the bit nobody writes down, so we'll try.

Trigger a digital touch (paid social, search, retargeted email) when:

• Portal valuation lookup detected in the postcode cluster
• Homeowner has engaged with your content before (newsletter open, blog visit, prior valuation request)
• Probate or estate signal — sensitive, lighter touch, digital first
• The address is outside your immediate canvassing radius but inside your fee zone

Trigger a door-knock or hand-written card when:

• Planning application granted on the street in the last 60 days
• A neighbour just sold above HPI trend (envy effect — 14-day window)
• The property has been on the patch for 18+ months since last sale with no obvious renovation (likely turnover)
• A negotiator had a "come back in six months" conversation that's now due

These aren't rules. They're starting positions. The point is that the channel choice should fall out of the signal type, not out of the manager's preference for one channel over the other.

Where most branches actually lose money

The waste isn't in the channel choice. The waste is in running both channels with no shared memory.

A homeowner who got a retargeted ad on Tuesday, a leaflet on Wednesday, and a negotiator on Thursday — all without any of those touches knowing the others happened — is being canvassed badly and expensively. They'll perceive the branch as either spammy or disorganised. Probably both.

The cheapest improvement most branches could make tomorrow has nothing to do with adding a channel. It's making sure the channels they already run can see each other:

1. Single source of truth for every homeowner contact, regardless of channel
2. The negotiator at the door can see, on their phone, whether this address has had a digital touch in the last 30 days and what it said
3. The marketing person running the ads can see which doors the team is knocking this week and exclude them from the ad set
4. The manager on Monday morning sees the full picture, not three reports from three tools

Do that and your cost per instruction across the board drops by a third without spending a penny more on either channel. We've seen it happen.

So what wins?

Neither. Both, stacked, with signal driving channel choice and a single conversation memory underneath. That's what wins in 2026.

CanvassIQ is the manager-led piece of that stack — the bit that ingests signal, assigns doors to negotiators, and keeps the conversation log that makes the rest of the marketing spend not wasted. It's in private beta with a small group of UK agencies. The CanvassIQ overview walks through how it fits next to whatever you're already doing on the digital side.
