Building consultancy describes a range of professional services concerned with a property’s condition, design, costs or management. It is not one fixed package. Before making an appointment, identify the decision you need help with and the expertise required to answer it.
Start with a clear question
Do you need to understand a defect, assess a proposed alteration, prepare repair work or manage a larger project? Those tasks may call for different professionals. A building surveyor, structural engineer, architect and cost consultant can have complementary roles, but they are not interchangeable.
Write a short brief covering the property, the proposed work, known problems, available documents and the decision you need to make. State any access limitations and the timing of your decision.
Agree the scope of the appointment
Ask what will be inspected, what investigation is included and what is excluded. Clarify whether the service is a visual inspection, a specialist assessment, design work, contract administration or another defined task.
Request a description of the deliverable: for example, an illustrated report, drawings, a schedule of repairs or an assessment of cost options. Agree how uncertainty and further investigation will be recorded.
Check the professional and the terms
Verify qualifications, relevant experience and professional membership directly with the organisations concerned. Discuss insurance, fees, complaints arrangements and any potential conflict of interest. Membership alone does not establish that every specialist service is within an individual’s experience.
The RICS consumer guides explain several surveying services and provide a starting point for deciding which type of help to investigate.
Keep advice and execution distinct
Establish whether the consultant will only advise or will also prepare documents, manage procurement and inspect work. Ask who appoints contractors and specialists and who is responsible for statutory applications. An inspection service does not automatically include continuous supervision or a guarantee of all workmanship.
Use the report to make a decision
Ask the consultant to separate urgent issues, planned work and matters that need further evidence. Check the assumptions behind any cost indication. Keep the report available to those who need it, subject to its terms of use.
If the advice leads to building work, define the next appointment and budget rather than assuming it is included. Our guide to comparing builders’ quotes shows how a clear scope supports a more useful price comparison.
