Bat survey quotations are easier to compare when they answer the same project brief. Look beyond the headline price to the site, proposed works, evidence stage and deliverables each offer covers. A clear clarification table helps identify differences without assuming that the cheapest quote or the greatest number of visits is automatically the most appropriate scope.
Give each consultant the same brief
Send the current existing and proposed drawings, a works description and any relevant previous reports. State the planning stage and the decision the team needs to support. Explain access restrictions and parts of the design that remain uncertain.
If the brief changes while quotations are being prepared, tell each consultant what changed. Comparing offers based on different layouts can conceal a scope difference that will matter later.
Compare assumptions and outputs
Ask what the quotation includes and which later decisions depend on initial findings. Distinguish an initial assessment from further survey work, reporting, design advice or licensing support. Avoid treating a provisional follow-up allowance as a final determination of the survey requirement.
Clarify access responsibilities, reporting format, exclusions and how the consultant will discuss limitations. The appointed ecologist should establish the appropriate method for the site and proposed works using relevant professional guidance.
Resolve differences before appointment
Use a clarification table with the question, consultant’s response and the item affected. Ask for a revised written scope where a response materially changes the offer. Keep pricing, programme assumptions and technical scope identifiable rather than mixing them into a single comparison score.
Use the responsible commercial contact to confirm current charges, VAT treatment and payment terms. This article gives no standard price, guaranteed programme or universal visit count. A like-for-like brief supports an informed appointment; it does not replace the consultant’s specialist judgement.
Information register
| Comparison | Question to ask |
|---|---|
| Starting information | Which drawings and earlier reports were assumed? |
| Included work | What assessment, survey and reporting are covered? |
| Dependencies | What could require a revised scope? |
| Practical arrangements | Who provides access and receives the output? |
A practical example
Illustrative example: One offer includes an initial assessment only, while another contains a provisional allowance for further work. The client records the distinction and asks both consultants to clarify the decision stages before comparing the prices.
Before the next issue
