Pre purchase structural engineers survey

Hi all,

Currently buying my first home in Douglas and struggling to find the right engineer to do the pre purchase survey. It’s easy to get an engineer, but finding one that fits all the criteria seems to be difficult.

Firstly, from roughly 10-12 quotes, they range from €600 to €900, then I ask how long the survey last on-site and I get a range of answers from “around 30 minutes” to “2.5-3 hours”.

The property was built in 1960, although not a very old property, old enough to want an engineer to have more than a 30 minute visual inspection.

Does anyone have a recommendation of an engineer from recent?

Also, sub question, has anyone gotten a drains test as well as pre purchase survey?

Thanks!
