The Level 3+ Building Survey
The Level 3+ is our most complete package — everything in a full Level 3 Building Survey, plus a reinstatement valuation, a summary of repair costs and aerial drone imagery, all included as standard.
You get the deepest assessment of construction and condition, together with the financial and visual detail to plan works and negotiate with confidence.
Who the Level 3+ suits
Perfect for older or altered properties where you want the fullest technical picture and the practical extras — rebuild cost, repair budgets and close-up roof imagery — without paying for them separately.
If you don’t need the added extras, a standard Level 3 Building Survey covers the full structural inspection.
What your report gives you
We inspect the structure, fabric and services in depth — then explain what we found, what it means, and what to do next.
You’ll also receive an email summary within 48 hours of the inspection, and you can always speak to your surveyor directly.
Defects & their causes. We report on defects and the most likely cause for each one we find.
How to put it right. We explain how to fix it — and what could happen if you don’t.
Who to call. We recommend where to find suitable contractors to carry out the work.
Clear & photo-rich. Detailed, photo-rich and easy to understand, written in plain English.
Traffic-light ratings. Every defect is rated with our simple traffic-light system, so priorities are clear.
Your Plus package includes
Everything in a Level 3 survey, plus these premium extras at no additional cost:
Reinstatement valuation
The full rebuild cost for insurance, so you’re never under-insured.
Summary of repair costs
Estimated costs for the defects we find, ready for budgeting and negotiation.
Aerial drone images
Close-up imagery of the roof and exterior from above.
Everything included, priced up front
The complete package in plain English. Level 3+ Building Surveys start at £850, subject to the property — with the Plus extras included.

Level 3+ Building Survey – frequently asked questions
What is a Level 3+ Building Survey?

At Flettons, a Level 3+ Building Survey starts from £850. The exact price depends on the property's size, type, age and complexity – enter your details for an instant, tailored quote.
When should I choose Level 3+ over Level 3?
Choose Level 3+ for the most complex or valuable properties – large period homes, heavily altered buildings, non-standard construction, or wherever you want the most detailed analysis and advice available.
What does a Level 3+ survey include?
Everything in a Level 3 Building Survey – a detailed inspection describing condition, defects, their cause and the repairs needed – plus extended analysis tailored to complex and high-value properties.

Both are detailed inspections. Level 3+ goes further than the standard Level 3, with additional detail and analysis suited to the most complex or high-value properties.
Is a Level 3+ survey worth it?
For complex or high-value homes, yes – the deeper analysis gives you the fullest possible picture of condition and risk before you commit to what is usually your largest single investment.
