Development Monitoring Surveyors in London, Surrey & Sussex
Independent monitoring for banks, funds and private lenders — initial due diligence, interim drawdown certification and GDV valuation, prepared to RICS standards. Clear, decision-ready reporting that protects your security through the build.
When a bank or fund lends against a construction project, the risk doesn’t end when the facility is agreed — it runs for the life of the build. Development monitoring is how lenders stay in control of that risk: an independent surveyor acting as their eyes and ears on site, confirming that money is only drawn down against real, verified progress.
At Blackacre, our chartered surveyors monitor high-value developments on behalf of banks, funds and private lenders across London, Surrey and Sussex. Because we provide both building surveying and valuation services in-house, we can monitor the build and report on Gross Development Value — which is why we sit on a number of bank and lender panels.
What is development monitoring?
Development monitoring is an independent review of a construction project carried out for the party funding it — a bank, fund or investor — to confirm the scheme is deliverable, on budget and on programme before and during drawdown.
The role is often called the Independent Monitoring Surveyor (IMS), or Lender’s Independent Monitoring Surveyor. The key word is independent: the monitor is appointed by the lender and reports to the lender, separately from the developer’s own project team. The role and its duties are set out in the RICS Lender’s Independent Monitoring Surveyor standard, the recognised benchmark for this work in England and Wales.
In short, the monitoring surveyor is the lender’s technical safeguard — translating what’s happening on site into a clear view of risk to the loan.
Why do lenders need a monitoring surveyor?
Because a development can drift off budget or programme long before it shows up in the borrower’s own reporting — and by then the lender’s security is already exposed.
A development is full of moving parts that can cause delay or unforeseen cost: planning conditions, contractor solvency, design changes, cost inflation, defective work, and more. An independent monitor identifies those risks early and gives the lender the evidence to act — whether that’s adjusting drawdown, requiring additional security, or pausing funding. Done well, monitoring protects the lender’s investment and keeps a viable scheme moving.
Our development monitoring service
We provide end-to-end monitoring across the life of a project:
- Initial appraisal / due diligence report — a full pre-commencement review so the lender understands the risk profile before releasing funds.
- Interim monitoring & drawdown certification — regular site inspections and reports (typically monthly) that verify progress and sanction each staged drawdown.
- Cost-to-complete monitoring — tracking actual spend against the development appraisal and cash flow, and confirming sufficient funds remain to finish.
- GDV valuation — Gross Development Value reporting from our in-house RICS Registered Valuers, so funding decisions are anchored to a credible end value.
- Practical completion & final account review — completion sign-off, retentions, defects and final-cost reconciliation.
What the initial report covers
Before a penny is drawn down, we review the whole project so the lender can fund with confidence. The initial report typically examines:
- The parties and the professional team's appointments
- Planning permission and conditions
- Building Regulations and (where relevant) Building Safety Act Gateway approvals
- The building contract and procurement route
- The construction cost budget and development appraisal
- The development programme and cash flow
- Collateral warranties, professional indemnity cover and insurances
- The overall adequacy and security of the development budget
From this we advise the lender on the risk profile of commencing funding, and flag anything that needs resolving before drawdown.
The monitoring process
Three stages, one continuous view of risk:
1. Pre-commencement
The initial due-diligence report establishes whether the scheme is sound and properly funded.
2. Construction
Interim reports track progress, spend and risk, and certify each drawdown so funds are released only against verified work.
3. Completion
We confirm practical completion, review retentions and defects, and reconcile the final account.
Development monitoring and the Building Safety Act 2022
For higher-risk buildings, building safety is now a funding risk — and the monitor helps lenders stay on top of it. Under the Building Safety Act 2022, higher-risk buildings (broadly those at least 18m tall or with at least seven storeys and two or more residential units) must pass through the Building Safety Regulator’s Gateway regime. The Regulator can issue stop notices and compliance notices that halt or rectify works — disrupting the programme, hitting cash flow and, in the worst case, threatening default. As part of monitoring, we track Gateway approvals and building-safety compliance through the build, so lenders aren’t blindsided by a regulatory hold on their security.

Frequently asked questions
They act independently for the party funding a development — a bank, fund or investor — reviewing the project before drawdown and inspecting throughout construction to confirm it’s on budget, on programme and properly managed, certifying each staged release of funds.
The monitoring surveyor is independent and reports to the lender, not the developer. The developer’s team manages and delivers the build; the monitor checks it on the lender’s behalf and protects the loan security.
A pre-commencement due-diligence review of the whole project — planning, contract, costs, programme, cash flow, warranties and insurances — that tells the lender the risk profile of funding the scheme before any money is drawn down.
At each stage, the monitor inspects the site and verifies progress and spend against the development appraisal, then confirms to the lender that the next tranche of funds can be safely released.
Yes. We have RICS Registered Valuers in-house, so we can provide the Gross Development Value valuation alongside monitoring — one firm for both, which many monitors can’t offer.
For higher-risk buildings it does. We track Building Safety Regulator Gateway approvals and building-safety compliance through the build, so lenders can see if a regulatory hold could affect their security.
