Tick tock.
You don’t need to, but you might want to for your own purposes. The mortgage company’s valuation is for them, and is simply designed to tell them (in effect) that if they had to repossess your place and flog it in auction they’d be more than likely to get their money back. That’s all they care about. It will have made a basic assessment that the place isn’t about to collapse, but not much more. Note also as it’s not made out to you you can’t claim on it if for instance the place does in fact collapse (and this should have been obvious).
You can have your own survey, at varying levels of detail, up to a few thousand pounds for a full structural. These will tell you (depending on the level of detail) about things that are or may be a problem that will require possibly expensive fixing. Whether to get one or not depends on what you might do with the information. One could potentially use it as a negotiating tool if eg expensive roof works are indicated. One could also use it to decide that one can’t afford the place after all (if eg expensive roof works are indicated, the seller won’t budge on price, and you know you won’t be able to afford them). One can use it as a to do list of things that you’ll need to do after you get it, with probably some kind of indication of the urgency.
You also get a level of protection if something bad happens that the surveyor should have noticed and didn’t - you can claim against the surveyors insurance. NB this usually has to be something so blindingly obvious that they missed that it rarely happens. But in theory it is there.
Just says I should redecorate as it's a little tired. And have an electrician check the electrics. Boiler due for annual service at the end of the month (does that mean it'll happen and they will pay for it as I'm sure completion won't be done by then)?
) so will check the plugs and things then.
