Whito directory · Advisers
Infrastructure advisers in the UK
6 firms listed, 23 September 2026. Each checked at Companies House, each with its named work or licence and the source.
What counts as advisers
An adviser designs, plans, costs or manages the work, but does not build it. That covers engineering consultancies, cost consultants, planning consultants and specialist lawyers.
A firm goes in the group that matches the work it has actually done, from a public source. See who builds what for the four groups.

How to check a firm in this group
An adviser does not pour concrete, so a named project for an adviser means a design, programme management or technical role. The profile says which role, and links the page that names it.
Big consultancies often have more than one UK company. WSP UK Limited is not the same company as the former Wood business now called WSP Environment & Infrastructure Solutions UK Limited. Check the number, not the logo.
Method. Each firm was checked at Companies House on 23 September 2026: legal name, number, status, incorporation date and registered office. The named work links to an official page, a regulator’s record or the firm’s own page.
Limits. A Whito listing is not a recommendation, rating or prequalification. It is not a list of every firm in this group, only the ones we have checked so far.
