Why sellers say yes

The agent with evidence
wins the instruction.

A seller cannot tell whether your number is judgement or flattery. Show them the workings and the question answers itself.

Floor area is never guessed

Taken from the EPC register against a matched UPRN. If it cannot be verified, the report says so and the confidence score falls.

Evidence is weighted, not averaged

Recent open-market sales of similar homes carry weight. Auction, probate and forced sales set a floor and never anchor the figure.

Every adjustment is shown

The full build-up, from base rate to final figure, with each adjustment named and priced. Nothing arrives as a single unexplained number you have to take on faith.

Inspect the evidence

Every comparable,
and what it was worth.

Price per square foot against sale date. Bubble size is floor area. Hover any point.

How valuations get made
  • A number chosen to win the listing
  • Three comparables picked from memory
  • Floor area taken from an old brochure
  • An auction sale treated as market value
  • Confidence expressed as certainty
  • The reduction conversation, six weeks later
How Evidata makes them
  • A number the evidence supports, and only that
  • Every comparable weighted and shown
  • Floor area verified against the EPC register
  • Forced sales set a floor, never the anchor
  • Thin evidence lowers the confidence score
  • A price that sells, defended line by line
Reading the confidence score

What 90 means. What 50
means. And what to do about it.

Every report carries two numbers: the valuation, and how much to trust it. The second one is what actually does the work when you're sitting on someone's sofa.

90–100About as good as it gets

Verified floor area, several fresh open-market comparables on the same street, nothing material left to confirm. Say the number and stop talking.

75–89Strong, sofa-ready

The basics are verified and the comparable evidence is decent. There may be one or two named gaps, but nothing that should worry a seller.

56–74Usable, with caveats

Real evidence, but thinner: older sales, fewer comparables, or something specific still to confirm. Worth naming before the seller finds it themselves.

55 and underCapped by design

Almost always one specific cause: the floor area has not been independently verified. Not a weak valuation — the system refusing to claim precision it doesn't have.

Raising a low score

The score isn't a dial you turn. It's a mirror.

It only moves when the evidence does, which is exactly what makes a 90 worth saying out loud to a seller. Four ways to move it, all inside tools you already have.

  1. Verify the floor area. This is what gets capped at 55 when it can't be confirmed, because it's the number everything else is built from. Check the EPC register or a measured floorplan, then enter it on the form yourself.
  2. Read "What We Checked." The report names, in plain English, exactly what's confirmed and what isn't. Go and verify the specific items in the third column before your next visit.
  3. Give the form more to work with. Extensions, upgrades, defects, drainage: thin answers make for thin evidence. The score reflects what you told us, not just what's public record.
  4. Run it again. A second report built on better evidence earns a genuinely different score, not a nudged one. That's what a seller is actually responding to, whether they know it or not.
How it works

Four steps. The last
one is a person.

The research is automated. The judgement is not. Read the playbook to see how to use each page of the report in the room.

01

Enter an address

A Royal Mail lookup pins the exact property. Add what you know from the visit, then review the nearby sales we have scored and tick the ones you want us to rely on.

02

Evidata builds the case

Verified floor area and EPC, sold evidence, live competition, planning and risk. You watch each stage tick over, or close the window and carry on.

03

The pack lands in your inbox

A branded vendor report, an on-site valuation guide, a site-visit guide, a research pack and a draft covering email. About fifteen minutes.

04

You review, then send

Nothing reaches the client until you decide. If the seller or you know something we did not, challenge the valuation with your evidence and we re-investigate.

The valuation playbook

The report is only half
of it. Here is how to
use it in the room.

A page-by-page guide to running a valuation appointment with the evidence in your hand. What to show, when to stop talking, and the one sentence that wins the instruction.

Every page of the report. One playbook. Every objection already answered before it's raised.
Read the playbook
On the comparablesEvery rival agent brings a number. You are the only one bringing the receipts.
On the curveWhen a seller asks for more, do not argue. Put a finger on the curve and let it answer.
On what you checkedYou are volunteering what you do not know, before anyone asks.
The one ruleNever defend the number. Defend the evidence.
Before you knock

Five minutes with the "What We Checked" page. Know exactly which claims are confirmed, and which you're about to test in person.

In the room

Open on the comparables, not the number. Let the evidence build to the figure, so it lands as a conclusion, not an opinion.

After the viewing

Send the curve, not a percentage. A seller who can drag the price themselves argues with the evidence, not with you.

Price against probability

Drag the price.
Watch the odds move.

This is the chart your seller gets. It turns a pricing argument into a conversation about evidence. Drag the handle, or use the arrow keys.

For any letting

An evidence-led rent,
whether it's a new listing or a sitting tenant.

A rental valuation report, built the same way as the sale-side report: named comparables, sourced context, an honest confidence score. Use it to work out what to market a new listing for, or to review a sitting tenant's rent — where a statutory increase is the reason for the review, it also checks a proposed Section 13 notice for you, a supporting detail on the report, not the headline.

01

Achieved-rent comparables

You supply the comparable lettings you know about — the strongest evidence a tribunal can weigh — and the report shows exactly how they build up to the proposed rent, weighted by how comparable each one really is.

02

Sourced context, not guesswork

The subject's own EPC, current asking rents nearby, an official ONS benchmark, and — where enough exist — a pooled, anonymised median from other Evidata agencies. Labelled evidence versus context throughout, never blended together.

03

AI research, working alongside you

Evidata's research assistant searches for further comparable leads and local market commentary, and sanity-checks your proposed figure against what it finds — internal notes for you to review, never added to the evidence automatically.

04

Section 13 compliance, checked

Where a statutory rent increase is the reason for the review, the report checks the notice period, the 52-week gap and the period alignment against the facts you enter, and flags the earliest compliant date if it isn't ready to serve yet.

Questions agents ask

Straight answers
before you try it.

Evidata is built and run by Simon Bourne, a working estate agent in County Durham (Bourne & Co), and operated by Bourne and Co Technologies Ltd. Questions: info@bournenco.com.

Is this a RICS Red Book valuation?

No. It is an evidence-based desk appraisal, and it says so on every page. It does not replace a survey, a mortgage valuation or your own judgement on the visit.

Whose valuation is it?

Yours. The report is evidence to support the advice you give. You review it first, check the facts on the visit, and decide what to tell the seller. Nothing is sent to your client unless you send it.

Will my professional indemnity insurance cover using it?

We cannot give insurance advice. Check with your insurer how it treats desk appraisals you prepare with a tool, the same as you would for any other tool you use.

What happens to the seller’s details I enter?

Their name and email are optional. We use what you enter only to build your report, using the providers listed in our Privacy notice. You remain responsible for having the right to enter it. We never contact the seller.

What do I get free?

Three property valuation reports and three rental reports, with just a Google sign-in. No card. Free reports are watermarked and marked not for client use. Buy credits or start a monthly plan and they carry your name, logo and fees.

How long does a report take?

About fifteen minutes. It is emailed to you, and you can close the window while it builds.

What if the report gets something wrong?

Challenge it with your own evidence. We re-investigate, and the first challenge on each report is free. Every report also says what it could not confirm, so you know what to check on the visit.

Can I cancel a monthly plan?

Yes, any time from your Billing page. You keep the reports you already have.

Stuff your compliance officer needs to see

No animations here.
Just the limits.

A valuation tool that oversells itself is the same problem in a different coat.

Not a RICS Red Book valuation

An evidence-based market appraisal. It does not replace a survey, a mortgage valuation, or legal due diligence.

It has never walked the rooms

It cannot smell damp, judge build quality, or feel whether a street is right. That is your job.

Only as good as local evidence

Strong on a street of near-identical semis. On a converted barn with no comparable for two miles, it says so.

It never contacts your client

Every report comes to you first. The review gate is deliberate and it is not optional.

Sources are named, with dates

Every verified fact carries its origin: certificate number, title, sale date. Nothing is asserted without provenance.

Assumptions are labelled as such

What the seller told us is separated from what the record proves. The report never blurs the two.

If you are selling

Ask for it by name.

Nobody buys a used car without a history check. Nobody should sell a house on an opinion. If the agent at your door has not brought an Evidata report, ask them why not.

A valuation you cannot check
  • A figure, and a confident smile
  • Comparables you never see
  • No way to tell evidence from flattery
  • A price cut suggested six weeks later
An Evidata report
  • Every comparable listed, dated and weighted
  • Floor area from the EPC register, not a brochure
  • Confirmed facts separated from assumptions
  • A confidence score that falls when evidence is thin
The only test that counts

Run it on a property
you already valued.

Pick one you know inside out. Compare the evidence against your own figure. If Evidata does not hold up, you have lost ten minutes. If it does, you have found the thing you carry into every valuation from now on.
