The honest workflow

Use both. Screen ten with us, instruct a QS for the one.

Smart developers use PropertyLord AI to screen 10 deals, then hire a quantity surveyor for the one they pursue. You save thousands in QS fees on deals that were never going to work, and you go to your QS with better numbers from day one.

The smart workflow

  1. 1Find 10 potential deals.
  2. 2Screen all 10 with PropertyLord AI in under 5 minutes.
  3. 3Shortlist the 2–3 that actually stack up.
  4. 4Hire a QS for your final pick — armed with real numbers.

Math: 10 deals × £3,500 in QS fees = £35,000 spent screening. The same shortlist via PropertyLord AI is targeted at £29/mo — with free tools already live while the deeper paid layer opens.

Where each tool earns its fee

When you need a QS, and when you don’t

A PropertyLord AI subscription doesn’t make a quantity surveyor redundant. It makes one affordable on every deal that actually deserves one.

Hire a quantity surveyor

When you genuinely need a QS

  • Complex builds with non-standard structural requirements.

    Anything where the spec drives the cost — not the postcode. A QS reads the drawings; we read the area.

  • Tender preparation and contractor negotiations.

    Once you’re comparing real quotes against a real bill of quantities, you want a qualified surveyor in the room.

  • RICS valuations a lender or investor will accept.

    PropertyLord AI is a feasibility tool, not a regulated valuation. For Red Book work, hire a RICS-registered QS.

  • Dispute resolution and contract valuations.

    If the project is already on site and the numbers are being argued over, that’s a QS job, not a software job.

Use PropertyLord AI instead

When PropertyLord AI is enough

  • Feasibility checks before you commit a deposit.

    Postcode in, build-cost estimate out, with the regional multiplier already applied. No QS invoice on a deal you might not pursue.

  • Initial budgeting for HMOs, conversions, and extensions.

    28 trades against the regional benchmark gets you a credible number for the offer letter — in 30 seconds.

  • Comparing 10 deals to find the 2 worth pursuing.

    Re-run the same model on every postcode in the pipeline. The cost of a single QS instruction screens the whole shortlist here.

  • HMO and conversion costing with regional accuracy.

    11 UK regions, RICS-benchmarked. Specific enough to tell a Birmingham flip from a Manchester conversion before you ring the agent.

One developer, one quote

What screening before the QS looks like in practice

“Illustrative pre-QS screen: a 2-unit new-build scenario in SW9 can return build cost (£210,600), SDLT (£8,300), and a 38.2% ROI estimate in one view — enough to decide whether the deal deserves a paid QS instruction or a hard pass.”

Five questions before the switch

What developers ask before swapping QS-on-every-deal for PropertyLord AI

Does PropertyLord AI replace a quantity surveyor entirely?
No — and we don’t want it to. For final tender, lender-grade RICS valuations, and disputed builds, hire a quantity surveyor. For feasibility, deal screening, and budgeting before you commit, PropertyLord AI gives you a credible number in 30 seconds. The paid launch layer is targeted at £29 a month; most developers we talk to use PropertyLord AI to screen 10 deals, then bring in a QS for the one they pursue.
How accurate is the build-cost estimate compared with a QS quote?
It uses 28 trades, three quality tiers, and 11 UK regional multipliers benchmarked against RICS data. Expect the PropertyLord AI figure to land within roughly 10–15% of a full QS bill of quantities on a standard build — close enough to make a confident offer, not close enough to sign a contract on. For final tender, you still want the QS.
Why do quantity surveyors charge £2,000–£5,000 per project?
A QS reads your drawings, prices each trade against current sub-contractor quotes, and produces a signed document that a lender or contractor will treat as authoritative. That’s real work and worth the fee — on the deal you actually pursue. The problem is paying it on every deal you screen, including the ones that never happen.
Can I send the PropertyLord AI output to a lender or contractor?
It’s an itemised feasibility, not a Red Book valuation. Lenders and main contractors will still want a QS-signed document for the project they’re funding or building. Use PropertyLord AI to decide whether the deal is worth instructing a QS in the first place.
What does PropertyLord AI cover that the build-cost figure alone doesn’t?
SDLT (HMRC-accurate, including the 3% surcharge), area risk flags (flood, planning, tenure), basic capital stack maths, and the build-cost engine itself. The paid launch layer is targeted at £29/month and is meant to cover the whole feasibility surface — not just the build-cost number.
