RPS (formerly CgMs): Heritage Impact Assessment Cost and Turnaround 2026

What they specialise in

Multi-discipline heritage plus archaeology plus EIA chapter. Tetra Tech ownership since 2023. Pricing model is bespoke per project. Verify on a per-case basis: heritage consultancies routinely flex fee in either direction based on scope, asset grade and the LPA's expressed expectations.

Where this vendor would typically sit on the four-band fee map

Band guidance, not a vendor-published rate. Work of this kind (bundled HIA and DBA work) sits in the HIA+DBA band of the four-band fee map published on this site (£1,500 to £5,000+). That range is this site’s own published fee model, not a price RPS quotes or publishes; commission a quote directly. See the methodology note for how the four bands are derived.

Verifying credentials before instructing

• Check the named author's RIBA, IHBC, CIfA or RICS-BCA accreditation directly on the relevant register.
• Request a recent case study where the LPA published its officer report, gives you third-party calibration.
• Confirm fee is ex VAT, and whether reasonable travel and out-of-pocket are included.
• Confirm the deliverable: PDF report, with or without sample wording for the Design and Access Statement integration.

What this site does not know

Where a consultancy does not publish per-project rates (most do not), the fee band shown is derived from market observation, comparable published quotes and case-study disclosures. Treat as indicative only; commission a quote directly. This site has no commercial relationship with the vendor.
