Lichfields is one of the UK's most-cited development-appraisal consultancies in S106 viability cases. The output is FVA evidence for a specific scheme, not a software licence. Engagement is quote-only; the deliverable is a signed report relied on at committee and at appeal.

Pricing position

Quote only; consultancy engagement, not a software licence. Source: lichfields.uk/services/economics-and-viability (verified 2026-06-21).

One of the UK's most-cited development-appraisal consultancies in S106 viability cases; provides FVA evidence rather than software, frequently named in committee reports and PINS decisions.

Lichfields publishes no list price. The engagement is a fixed-fee consultancy report sized to the scheme and the policy context.

Software vs consultancy

Aprao and Argus Developer are appraisal software. Lichfields is the consultancy retained either by the applicant to author the FVA or by the LPA to review it. Both seats use the same underlying RICS FVP methodology; the difference is who signs the report and who defends it at committee or at appeal.

When Lichfields is retained

Where the policy-compliant tariff is materially contested and the contribution shortfall justifies a specialist FVA, the applicant retains Lichfields (or a peer consultancy) to author the report. The LPA typically retains DSP or Three Dragons to review it.

S106 + CIL + BNG handling

Lichfields handles the three layers as cost lines in the same residual-appraisal model: S106 contributions tied to the consent triggers, CIL at the per-sqm rate, BNG at the chosen delivery route. The report exposes the RLV impact of each layer separately to support negotiation.
