The role of the monitoring surveyor
A monitoring surveyor (MS) is a qualified professional appointed by the lender to independently verify that construction work is progressing as planned and that build costs are in line with the approved budget. They act as the lender's eyes on site — their reports determine whether the next tranche of funding is released.
What does a monitoring surveyor check?
At each drawdown stage, the monitoring surveyor visits the site and assesses:
- Work completed to date — does the physical progress match the claimed stage of completion?
- Quality of workmanship — is the work being done to an acceptable standard?
- Budget tracking — are costs on track with the approved budget, or are there signs of overspend?
- Programme — is the project on schedule? If delayed, what is the likely impact?
- Health and safety — is the site being managed safely?
- Compliance — are building regulations being followed? Are warranty inspections up to date?
How drawdowns work
Development finance is drawn down in stages, typically tied to construction milestones. A common drawdown schedule for a new build might be:
- Day one: land acquisition advance
- Tranche 1: substructure complete (foundations)
- Tranche 2: superstructure complete (walls, roof)
- Tranche 3: first fix (plumbing, electrics, plastering)
- Tranche 4: second fix and decoration
- Tranche 5: external works and practical completion
The monitoring surveyor must sign off each stage before the lender releases the corresponding tranche. This protects the lender from advancing funds for work that hasn't been done.
Typical costs
Monitoring surveyor fees range from £500 to £1,500 per visit, depending on scheme size and complexity. A typical project might require 4–8 visits over the build programme. The borrower pays these fees, and they should be included in the development appraisal.
Tips for smooth drawdowns
- Plan drawdown requests around completion of defined stages — don't request a drawdown mid-phase.
- Keep photographic records of work in progress to support your claims.
- Maintain organised documentation — invoices, certificates, building control sign-offs.
- Communicate proactively with the monitoring surveyor about any changes to the programme or costs.
- Ensure your contractor understands the drawdown process and timing requirements.
