Clear professional fees, with the scope agreed before we start.
Use the guide prices below or our fee calculator for an initial indication. We then review the property, location and required scope and confirm a fixed quotation before arranging the survey or site visit.
Useful starting prices without forcing every property into the same box
The prices shown are starting points for straightforward instructions. Larger, older, more complex or unusually detailed properties and sites are priced according to the work actually required.
Property size, construction, number of rooms, access, location, site conditions, survey equipment, CAD or reporting time and the agreed deliverables can all affect the final fee.
Use the guide-price calculator for an initial estimate. Williams Survey & Design will then confirm the scope and fixed professional fee before you decide whether to proceed.
Detailed, independent and technically informed
Inspections and reports are undertaken by Luke Haworth ACABE, Associate Member of the Chartered Association of Building Engineers (CABE), combining professional built-environment qualifications with extensive practical construction, surveying and building-defect experience.
Williams Survey & Design holds appropriate Professional Indemnity and Public Liability insurance. Our property surveys are professional, detailed building inspections tailored to the construction, condition and complexity of the individual property.
Our surveys are not RICS Home Surveys or mortgage valuations. A RICS Home Survey is a specific product provided within the RICS framework. Williams Survey & Design reports are independently scoped professional reports. This does not mean a reduced level of inspection or technical consideration; the appropriate depth of inspection and reporting is agreed to suit the building and the client's requirements.
Where a lender, insurer, solicitor or other third party specifically requires a RICS Home Survey, RICS valuation or an MRICS/FRICS surveyor, this should be confirmed before instruction.
Professional inspections for buyers, owners and landlords
Essential Condition Report
A concise professional overview of the accessible property condition, key defects and matters requiring attention.
Detailed Property Survey
A more detailed whole-property inspection and report for purchasers or owners who want greater explanation of construction, condition, defects and likely next steps.
Comprehensive Building Survey
Our most detailed general building inspection for older, altered, larger or more complex properties where a greater level of technical assessment and reporting is appropriate.
Property Condition & Defect Survey
Whole-property condition recording with room-by-room defects, photographic evidence and practical reporting. Particularly suitable for landlords, owners and commercial property clients.
Focused Defect Investigation
Targeted investigation of cracking, moisture, movement, roofing, brickwork or another defined building defect. Multiple or technically complex defects are individually quoted.
Independent checks before and after completion
New-build inspections are undertaken for the buyer, independently of the developer.
NHQB Pre-Completion Inspection
If your developer operates under the New Homes Quality Code, you may be entitled to appoint a suitably qualified professional to inspect your new home before legal completion. The inspection follows the prescribed New Homes Quality Board pre-completion checklist and records identified items with supporting notes and photographs.
Full New-Build Snagging Survey
A broader room-by-room inspection for visible workmanship defects, incomplete items and matters requiring attention, supported by photographic evidence and a clear professional report for the client and developer.
Reinspection
A return inspection to review previously reported items following remedial works. The fee depends on the property size and number of items requiring review.
Which inspection do I need?
An NHQB inspection is a prescribed pre-completion inspection. A full snagging survey is a separate, broader service. Tell us the developer, development and expected completion date and we can confirm the appropriate service before instruction.
Survey information for design, planning and development
Measured Building Surveys
Accurate existing plans and, where required, elevations and sections for planning, alteration, refurbishment and record purposes. Fees reflect property size, complexity and required CAD deliverables.
Topographical & Site Surveys
Levels, boundaries, buildings and relevant site features surveyed using appropriate professional equipment. Fees reflect site area, terrain, access, feature density, required control/datum and CAD deliverables. Development and complex sites are individually quoted.
Planning and technical design
Measured Survey, Design & Planning / LDC Package
For straightforward domestic extension projects where the scope is clear and the existing property is reasonably simple to survey.
- Measured property survey
- Existing plans and elevations as required
- Proposed floor plan and elevations
- Site / block and location plans
- Design development
- Planning, Prior Approval or LDC drawing package as appropriate
- Application preparation and submission where included in quotation
Local Authority and Planning Portal charges are additional.
Building Regulations Drawings & Specification
For a straightforward domestic extension following agreement of the design and planning position.
- Construction build-ups and technical notes
- Building Regulations information
- Key junctions and construction details
- Coordination of structural information where provided

Planning Feasibility / Pre-Design Advice
Useful where the planning position is uncertain, the proposal is unusual or you want to understand constraints before committing to a full design package.
Two-Storey Extensions, Loft Work & Small Development
Where planning risk, survey requirements, structural coordination or technical complexity are materially greater, we provide a project-specific quotation.
Tell us a little about the property or project
The calculator provides an initial professional-fee estimate from the information supplied. It includes a broad location allowance where applicable but does not separately display mileage or travel charges. The final fixed quotation is confirmed by Williams Survey & Design before any visit is arranged.
A clearly defined professional service
Before instruction, we provide a written quotation setting out the agreed scope, professional fee and any important exclusions or assumptions.
For survey and inspection work, ordinary travel and equipment requirements considered when preparing the quotation are incorporated into the professional fee rather than presented as a list of small additional charges.
Third-party and statutory fees
Planning, design and development projects may require separate third-party or statutory costs. Not every project requires all of the following.
Professional fees are only one part of the project budget.
Our separate guide explains typical 2026 construction cost ranges and how structural openings, large glazing, roof lanterns, kitchens and other design choices can affect the overall build cost.
