The gap in the due diligence stack

An auction legal pack review (typically £300 to £600 including VAT, with industry research putting the average around £429 plus VAT) covers title, searches and contract terms - it expressly does not cover planning potential or value. The instruments that do cover planning run on consultant timelines. This report fills the gap between the two.

Option	Cost	Turnaround	What it covers
Site Planning Report	£395 fixed, no VAT	24 hours from payment	Planning potential, risk, comparable approvals, constraints, the likely route and indicative numbers - PDF plus structured JSON data file
Chartered planner advice note	£1,500 to £5,000	4 to 6 weeks	Bespoke planning advice - thorough, but usually outside an auction or bridging timetable
RICS Red Book valuation	£750 to £1,500	2 to 3 weeks	Regulated valuation of the asset as it stands - required for some lending, silent on the planning route

The report is a pre-bid decision tool, not a substitute for regulated advice: where a transaction requires a Red Book valuation or formal planning evidence, you still instruct a RICS valuer or chartered planner - on the sites the screening says are worth it.

Built for acquisition workflows

A line item, not a consulting engagement

At £395 fixed per site you can run planning due diligence on every shortlisted lot, not just the one you have already half-decided to buy. A chartered planner advice note at £1,500 to £5,000 only makes sense after the site is under control; this report is priced for the screening stage before it.

Inside the acquisition timetable

Delivered within 24 hours of payment. That fits between catalogue release and auction day, inside a bridging credit deadline, or within a receiver’s disposal window - the points where a 4-to-6-week consultant timeline is simply unavailable.

A data file your models can ingest

Every report ships as a PDF plus a structured JSON data file: the verdict, the indicative key numbers, the ranked risks and the verification score in machine-readable form. Drop the figures straight into an IC pack, a lending model or your pipeline tracker without retyping.

An audit trail a credit paper can cite

Each report carries a verification score - how many of its facts were verified at source - and a published sources audit listing where every fact came from. When a credit committee or an investor asks "how do we know?", the answer is on the page.

The deliverable

Eight sections, identical on every report, whether you buy one or ten. Delivered as a PDF plus the structured JSON data file.

Lichfield, Staffordshire

Administration disposal

Part-built 22-flat shell, sold out of a contractor failure

The contractor went into administration in 2021 and the shell stood part-built and weathering until it sold at auction for £450,000 in February 2026. The report verified three live consents for 22 flats at source, put the consented residual at £341k and the developer ceiling at £513k, and showed the hammer price returns 16.9% profit on cost only if the standing structure can be relied on - naming the structural survey as the check that decides the whole deal.

Bid ceiling discipline

42-dwelling outline consent, guided £2.75m

A 6.3-acre former football ground with outline consent for 42 dwellings, guided at £2.75m. The report worked the residual: at a 17.5% margin the land is worth £1.105m, and the absolute bid ceiling at a 15% profit-on-cost floor is £1.61m. The guide implied a 4.6% margin. The room agreed - the lot drew no bids.

Questions acquisition teams ask

Can I use the report in a lender pack?

Yes, for pre-bid and internal credit decisions. The report carries a verification score, a published sources list and a structured JSON data file, so an IC paper or lending memo can cite exactly which facts were verified at source and which were not. For regulated submissions - a Red Book valuation, or formal planning evidence in an application or appeal - you need a chartered planner or RICS valuer sign-off, which this report does not replace.

Do you offer volume pricing?

Yes. A single report is £395. A 3-pack brings the per-report price to £355 (£1,065 total) and a 10-pack to £308 (£3,080 total). Pack credits are valid for 12 months and can be used on any UK property. For more than ten reports a year, email hello@mayfairstudio.co.uk and we will set up a billing account.

What is in the data file?

Every report is delivered as a PDF plus a structured JSON data file containing the report’s key numbers in machine-readable form: the verdict band, the indicative figures behind the appraisal (end value, build cost, residual and maximum bid), the ranked risks, the planning constraints and the verification score with its sources list. It is built to drop into an IC pack, a lending model or an internal database without retyping.
