5-Stage Refurbishment Bridging Process

How refurbishment bridging works from acquisition through project completion

Stage 1

Acquisition & Property Analysis

5-7 days to completion

Purchase property with bridging loan based on ARV (After Refurbishment Value)

Lender assesses property's potential value post-refurbishment, not current condition

Stage 2

Planning & Contractor Procurement

2-4 weeks

Secure planning permission if needed, obtain Building Regulation approval, appoint contractors

Some bridging lenders can drawdown funds before work commences to cover soft costs

Stage 3

Staged Drawdowns Begin

Throughout project

Release funds progressively as work completes key stages (foundations, structure, fit-out)

Contractor deposits typically 25% upfront, 50% mid-stage, 25% completion. Borrower needs working capital.

Stage 4

Quality Checks & Payments

Ongoing throughout project

Lender's surveyor inspects work at each stage before releasing next drawdown

Lender protects investment and ensures work quality. Delays if work is substandard.

Stage 5

Completion & Exit

Variable - 3 months to 2+ years

Project complete, Building Regulation completion certificate obtained

Exit via refinance to mortgage, sale, or hold-to-rent. Bridge repaid from refinance or sale proceeds.

Understanding GDV & ARV Calculations

How lenders calculate loan amounts based on post-refurbishment property value

Example: £250k Property + £80k Refurbishment

Current Property Value

£250,000

Market value of property in current condition

Refurbishment Costs

£80,000

Full project budget including labor, materials, contingency

After Refurbishment Value (ARV)

£350,000

Estimated market value post-completion. Conservative 10-20% uplift typical.

GDV (Gross Development Value)

£350,000

For refurbishment, GDV equals ARV. For multi-unit development, total of all units.

LTV Calculation

£262,500

At 75% LTV: Purchase (£250k) + Refurb (£80k) ÷ GDV (£350k) = 94% of funds available

Funding Gap

£67,500

If total cost £330k but LTV allows £262.5k, you need £67.5k equity or contingency

Key Takeaways:

  • Lenders lend on post-refurbishment value (ARV/GDV), not current property value
  • You can borrow up to 75% of total project costs (purchase + refurb) at 75% LTV
  • Owner equity in project demonstrates commitment and reduces lender risk
  • Conservative ARV estimates are better—lenders validate via independent valuation

Frequently Asked Questions

Get answers to the most common questions about bridging loans

Light refurbishment (cosmetic work, £5k-£30k, 4-8 weeks) is for decoration and minor repairs—fastest and cheapest financing. Heavy refurbishment (structural work, £30k-£150k, 8-16 weeks) includes major systems replacement and rewiring—more complex underwriting. Full development (extensions, conversions, £150k+, 16-52 weeks) requires planning permission and multiple staged drawdowns. All use ARV/GDV calculations, but development carries highest complexity and longest timeline.
Rather than receiving all funds at completion, drawdowns release progressively as work completes key stages: (1) Acquisition/soft costs drawdown, (2) Foundation/structure stage, (3) Mid-stage (roof, windows, systems), (4) Fit-out stage, (5) Completion. Lender's surveyor inspects before each release, protecting the loan security. This protects both lender and borrower by ensuring work quality and preventing disputes over work completion.
ARV (After Refurbishment Value) is the property's estimated market value post-completion. GDV (Gross Development Value) is total value of all completed units in multi-unit projects. Lenders lend based on GDV/ARV, not current property value. For example: property £250k + refurb £80k = ARV £350k. At 75% LTV, you can borrow £262.5k total. This means you need owner equity or contingency for the funding gap.
Rarely. Most lenders offer up to 75% of ARV/GDV, which includes purchase price AND refurbishment costs. Some specialist lenders may offer up to 80-85% for strong borrower profiles. For example: £250k purchase + £80k refurb costs = £330k total at 75% LTV of £350k ARV = £262.5k available. You'd need £67.5k equity. Having owner equity demonstrates commitment and reduces lender risk significantly.
Most bridges are available for 1-24 months, with typical refurbishment terms being 6-18 months. Light refurb bridges might be 6-9 months; heavy refurb 9-15 months; full development 15-24 months. Extensions are possible if project runs longer (common for planning delays or contractor issues). Discuss realistic timelines upfront—underestimating project duration is costly as interest accumulates monthly.
Budget overruns are common in construction (typically 10-20% contingency needed). If overruns exceed bridge funding, you have limited options: (1) Use personal equity to cover excess, (2) Seek additional funding from lender (usually expensive), (3) Scale back remaining work and sell, (4) Refinance to development loan if property now worth more. Prevention is critical—budget conservatively, use fixed-price contractor quotes, and maintain contingency reserves.
Yes, absolutely. Many property investors use refurbishment bridging to acquire, improve, then refinance to buy-to-let mortgages. The timeline is critical: complete refurb quickly, get property ready for tenants, apply for BTL refinance (typically requires 75%+ occupancy or pre-let agreements). Interest costs must be factored into yield calculations. FastBridge specializes in bridging investors' BTL portfolios.
Depends on scope. Light cosmetic work (decorating, kitchen, bathroom) rarely needs planning. Heavy refurbishment triggering Building Regulation approval (structural work, electrical rewiring) requires Building Control inspection but not necessarily planning. Extensions, conversions, and external changes usually need planning permission. Always check with your local council early—planning delays kill development timelines and increase bridge costs significantly.
