How Staged Drawdown Works

  1. 1

    Purchase drawdown

    Funds to complete the property purchase drawn on day 1 - typically 70% of the purchase price or agreed value.

  2. 2

    Works tranche 1

    After the monitoring surveyor confirms initial works are complete to specification, the first works tranche is released - usually 30–40% of the total works budget.

  3. 3

    Works tranche 2

    On confirmation of further milestone completion, the second works tranche is released. Timings and number of tranches are agreed at outset.

  4. 4

    Final tranche / retention

    The final tranche (sometimes 10% held back as retention) is released on practical completion and final inspection sign-off.

The Monitoring Surveyor

The lender appoints a monitoring surveyor (project monitor) to protect their investment by inspecting and certifying works at each drawdown stage. The surveyor visits the site, compares progress against the agreed schedule of works and cost plan, and issues a certificate confirming the tranche can be released.

Monitoring surveyor costs are typically £500–£2,000 per inspection, borne by the borrower. Experienced developers factor this into their cost plan. We can recommend monitoring surveyors familiar with the major heavy refurbishment lenders, which helps keep the process moving.

FAQs

Frequently asked questions

What types of works qualify as heavy refurbishment?

Heavy refurbishment includes structural works such as removing load-bearing walls, building extensions, loft or basement conversions, change of use, and anything requiring planning permission or building regulations approval.

What is a monitoring surveyor and why is one required?

A monitoring surveyor is appointed by the lender to inspect the works at each stage before releasing the next tranche of funds. They confirm works have been completed to schedule and standard. Their cost (typically £500–£2,000 per inspection) is usually borne by the borrower.

How does staged drawdown work on a heavy refurbishment loan?

The works element of a heavy refurbishment loan is drawn in stages rather than on day 1. You draw purchase funds on completion, then works funds are released in 2–4 tranches as construction milestones are reached and confirmed by the monitoring surveyor.

Do I need planning permission before I can apply?

Most heavy refurbishment lenders want to see planning permission in place (or at least submitted and likely to be granted) before they will offer terms. Some lenders will consider cases where permitted development rights apply.

What is the exit strategy for a heavy refurbishment bridging loan?

The main exit routes are: sale of the completed property, refinance onto a buy-to-let or commercial mortgage once works are complete, or a development exit loan if the project has grown in scale.
