We've had the survey back on the house we're hoping to buy. It's a 90s-build which is fairly tired but no major issues have been flagged up, but some things will need updating soon - eg double glazing is at the end of its life, as is the conservatory, and it recommends a full re-wire.
Survey doesn't say how old the boiler is but its last service certificate is from 4 years ago. The heating wasn't on when the survey was carried out so no idea if it even works. Would it be unreasonable to ask for an up-to-date boiler service? Do people ask for this? Or does this come under 'buyer beware'?
