A buyer gets three quotes. They differ by a considerable margin and she chooses the cheapest, reasonably enough.
What she has actually bought is a different product. The cheaper quotation was for a lower level of inspection, which will not lift floor coverings, will not inspect the roof space in the same detail and will report differently.
Eight months later a problem appears that a higher level survey would have flagged. The quotations were never comparable and nothing on any of them said so.
What a survey fee is made of
Four components. The level of inspection, the property itself, the location and travel, and the surveyor's own experience and insurance position. Only the first two are usually discussed.
Component 1: the level of survey
The single largest factor. A basic condition report, a mid level homebuyer inspection and a full building survey are different pieces of work with different durations and different reports.
Component 2: the size of the property
Usually the main driver within a level. More rooms, more floors and more outbuildings means more time on site and more to report on.
Component 3: the age and construction
Older properties, unusual construction, extensions, conversions and anything altered take considerably longer and carry more risk for the surveyor.
Component 4: location and travel
Distance, access and how much of the day a single inspection consumes. A rural property an hour from anywhere costs more for reasons that have nothing to do with the building.
A worked example
A three bedroom modern semi detached house. A basic condition report might be around four hundred pounds, a mid level inspection around six hundred, and a full building survey around nine hundred.
The same property at two hundred years old
The full building survey becomes the appropriate choice rather than an upgrade, and the fee rises again because the inspection genuinely takes longer and the report is considerably more detailed.
What that comparison is actually for
To show that comparing three numbers without comparing the levels is comparing nothing. The question is which level the property needs, and then what it costs.
What is excluded and frequently assumed
Drains, electrical testing, gas, structural engineering calculations and specialist damp or timber investigation. These are separate and their absence surprises people, which is the ground in damp and timber survey enquiries from worried owners.
The valuation confusion
A lender's valuation is not a survey and provides almost no information to the buyer. A great many people believe they have had a survey when they have not.
What the report should include
A clear rating system, photographs, what needs attention and how urgently, and what requires further investigation. Reports vary considerably in usefulness at the same price.
Ask about turnaround before booking
Buyers under time pressure need to know when the inspection can happen and when the report arrives, because both affect a chain.
Ask about the surveyor's experience with that property type
Period properties, timber frame, thatch and converted buildings all benefit from somebody who sees them regularly.
The commercial version works differently again
Lease obligations, dilapidations and different report formats, which is the ground in commercial survey and dilapidations enquiries.
Answer the level question before the price question
An assistant that establishes the property type, age, size and the buyer's concerns, recommends the appropriate level, explains what is excluded and quotes accordingly gives a buyer a comparable number rather than a cheap one.
