Depends if you can afford not to sell. Have you had other offers? Do you need to move?
You accepted an offer. That is the price for your house, as seen. Your asking price is irrelevant, it was just a guess by you and the EA at what someone might be prepared to pay, so the current value.
The big question with the survey results is do they raise issues that are not visible to a buyer viewing the house? Things that are hidden, or things that would not be obvious on casual, visual inspection?
So, window frames might appear to be ok (e.g. if recently painted over) but, if looked at closely by an expert, or prodded, prove to be rotting, loose or otherwise to need replacing.
I have been a buyer who asked for a similar amount off after survey, because there were rotting joists, potential asbestos in a roof and (I think, long time ago) rotting window frames. Pulling up the floor to deal with the joists would have delayed our moving in, so cost us extra mortgage / rent payments in the meantime.
That seller refused to reduce the price, we walked away. The house wasn't worth our (below asking but actually very generous) offer price, in that state. The seller's erroneously thought it was, because other, far better maintained, houses on the street had gone for similar or more. I don't they sold and eventually took it off the market.
