The higher level of experience a structural engineer has, the more likely it will be that they will charge you higher rates than what most others would for the same job. This is because experienced structural engineers are much more likely to complete a job error-free, in a relatively limited amount of time, compared with a relatively inexperienced structural engineer.If the property in question has expensive fixtures and fittings, you should go for a more experienced structural engineer than opting for a slightly cheaper alternative.
