The short answer: Good access helps a surveyor inspect more of the property safely. Buyers should coordinate with the seller or estate agent rather than entering or moving anything without permission. A Level 3 survey is more detailed, but it does not make locked or unsafe spaces accessible.
Agree access with the agent or occupier
Check who is meeting the surveyor or releasing the keys and whether the property will be occupied. If there is a tenant, a managing agent or a shared entrance, access may need more coordination than a single appointment with the selling agent.
Flag any alarm, parking constraint, dog or other practical issue in advance. Avoid passing sensitive access codes around unnecessarily; use the arrangements agreed with the surveying practice and the person responsible for the property.
Ask the seller to make ordinary access available
The owner should only make changes that are safe and appropriate. Do not climb into a loft, lift a heavy drain cover or disturb suspect materials just to prepare for a survey.
- Keys for relevant rooms, garages and permanent outbuildings.
- A clear route to roof-space hatches and accessible inspection points.
- Reasonable access around walls, windows and service equipment.
- Permission and keys for relevant shared areas where these can be arranged.
- Information about fragile fittings, unsafe areas or equipment that should not be operated.
Send useful information before the visit
Provide your concerns in writing, ideally with the room or location clearly identified. “Cracking above the rear kitchen door” is more useful than “please check the structure”. Mention previous extensions, a converted loft, known leaks or planned changes after purchase.
Available plans, completion certificates, guarantees and maintenance records can help advisers ask better questions. Documents do not prove that concealed work is sound, and the conveyancer still needs to check the relevant legal position.
What if part of the building cannot be inspected?
The report should identify material inspection limitations. A room full of stored goods, an unsafe roof space or a locked shared area can leave uncertainty. “Not inspected” is not the same as “no defect”.
Ask which restriction matters to your purchase decision and what would resolve it. The answer might be improved access, documents, a return visit or a different specialist investigation. Any additional service or fee should be agreed rather than assumed.
Can the buyer attend the survey?
Ask the surveying practice before making arrangements with the seller. Attendance is not automatic, and a quiet inspection may be needed to avoid interruptions. A short discussion afterwards or a separate report call may be more useful than following every part of the visit.
If attendance is agreed, follow safety instructions and do not expect access to areas the surveyor considers unsafe. Important conclusions should still be read in the final report, not treated as settled during an informal conversation.
Keep a short list of follow-up questions
After receiving the report, ask: what could not be inspected, how significant is that uncertainty, and what should be done before exchange? This turns an access limitation into a practical next step. It is more useful than asking the surveyor to guarantee a concealed part of the building they could not see.
Frequently asked questions
Will the surveyor move furniture or lift fitted carpets?
Do not assume this. Standard home surveys are not an unrestricted opening-up exercise. Agree any additional investigation separately, with the owner’s consent and appropriate safety arrangements.
Does the seller have to be at home?
The practical arrangement varies. The surveyor needs agreed safe access, which may be provided by the occupier, estate agent or another authorised person.
Is a blocked loft hatch a reason to cancel?
Tell the practice before the visit. It can explain how this affects the inspection and whether access should be resolved before proceeding.
Which survey is right for the property?
Compare our Level 2 Home Survey and Level 3 Building Survey. Share the address, age, construction, alterations and your concerns before choosing. A more expensive level is not automatically the right answer for every home.
