A building survey takes 2–4 hours on site, with the written report delivered within 3–5 working days — so from booking to report in hand, allow one to two weeks. Here's the full timeline by survey level and property size, where delays actually come from, and how to compress the schedule when exchange is looming.
Inspection time by survey level and size
- Level 2 HomeBuyer survey: 1–2 hours for a typical 2–3 bed home; 2–3 hours for larger houses.
- Level 3 Building Survey: 3–4 hours for a typical home; 4–6+ for large, period or extended properties — the surveyor is examining construction and fabric in depth, not just rating elements.
- Flats: usually at the quick end, plus time on communal parts and roof access where possible.
The end-to-end timeline
Day 0: instruct and pay — with us, a fixed quote usually lands within hours. Days 1–5: access arranged with the seller or agent — genuinely the slowest link in the chain (see below). Inspection day: 2–4 hours as above. +3–5 working days: the written report arrives, followed by your call with the surveyor. Total: 7–14 days booking-to-report for most purchases — comfortably inside a normal conveyancing window if you book when your offer is accepted rather than when searches complete.
Where delays really come from
Not the surveying. The bottleneck is nearly always access — tenanted properties, sellers on holiday, agents slow to hand over keys. Second is late booking. What doesn't delay things: a defect-heavy property (the report just gets longer) or bad weather (roofs get inspected from vantage points regardless, with limitations noted).
How to keep it fast
Book the moment your offer is accepted; give the surveyor the agent's direct line; warn tenants early if the property is let; and tell us your exchange deadline up front — time-critical surveys get prioritised slots and expedited reports. Choosing between levels? Speed is similar; depth differs — see which house survey do I need and what a building survey includes. After the report lands, the renegotiation window is where days matter most — our renegotiation guide covers it.
