The annual list covers companies employing mainly quantity surveyors, surveyors, project managers, engineers and architects by fee turnover ranging from large PLCs to limited companies and partnerships. The size of companies stretches from over £1bn to £100,000 in turnover. The Top 150 also provides a breakdown of the chartered specialists into separate listings by firms employing those specialisms. &²Ô²ú²õ±è;

The survey includes sentiment questions that will cover market conditions, skills, the use of artificial intelligence in construction, hybrid working arrangements amongst services companies and political and policy conditions currently facing the sector. &²Ô²ú²õ±è;

Chloe McCulloch, editorial director at Ðǿմ«Ã½, said: “The Top 150 Consultants list always offers a fascinating picture into the state of the services sector as well as the wider economic and political environment facing companies. 

“We want as many firms as possible to enter this year so as to ensure we’re capturing as full a picture of the sector – so please do make sure you take part this year regardless of your size. Please make sure you fill in the survey.â€

The deadline for completing the survey is Friday 13 June. Companies can start filling in the survey and return to complete it at a later date ahead of the deadline. &²Ô²ú²õ±è;
