LendInvest and MDA Consulting publish joint whitepaper to guide property sector through impending building safety levy
LendInvest (LSE: LINV), a leading development finance provider, along with MDA Consulting Limited, a premier construction monitoring consultancy, have released a joint technical whitepaper titled Building Safety Levy: Implications for Lenders & Monitoring Surveyors.
The paper arrives as the UK government’s new mandatory Building Safety Levy (BSL) comes into force under Section 58 of the Building Safety Act 2022 and the Building Safety Levy (England) Regulations 2025. Designed to raise approximately £3.4bn over ten years to remediate legacy building safety defects, the Levy represents one of the most significant shifts in UK development finance and site appraisal mechanics in recent years.
The whitepaper provides developers, lenders and monitoring surveyors with an actionable framework to navigate regional rate structure, Gross Internal Area (GIA) calculations, brownfield discount criteria and transitional exemption windows.
Key Technical Insights & Sector Takeaways:
- Universal Residential Scope: The BSL applies to all major residential developments in England creating 10 or more dwellings, or 30 or more Purpose-Built Student Accommodation (PBSA) bedspaces. Crucially, the whitepaper addresses a widespread industry misconception: the Levy applies regardless of building height, catching low- and mid-rise developments alongside high-rise schemes.
- Significant Variable Regional Rates: Local authority charges vary substantially based on regional property valuations, ranging from £12.70/m² in County Durham to £100.35/m² in the Royal Borough of Kensington & Chelsea.
- The 50% Brownfield Discount: Schemes constructed on Previously Developed Land (PDL) can qualify for a 50% rate reduction, provided at least 75% of the consented site meets the statutory PDL definition. The paper highlights the rigorous verification and evidence gathering required to secure this discount safely at underwriting.
- Pre-Completion “Bullet Cost” Risk: Payment of the Levy is triggered as a single upfront cost before the first completion or occupation certificate is issued. Failure to accurately budget or fund the BSL will result in building control authorities withholding completion certificates—directly blocking unit sales, refinancing, and ultimate loan redemptions.
- Transitional Window Urgency: Building control applications submitted before 1 October 2026 are exempt from the BSL, provided works substantively commence on site within three years of the initial application.

Dan Lohn, relationship manager at LendInvest, said: “As property development lenders, our role extends beyond providing capital; it’s about offering certainty as developers navigate major regulatory shifts like the Building Safety Levy.
With the Levy directly impacting scheme viability, cashflow timing and completion sign-offs, proactive partnerships are essential. By joining forces with MDA Consulting, LendInvest is delivering practical clarity on complex calculations, brownfield exemptions and adapted funding structures to help SME developers manage these obligations and keep projects moving forward securely.
Chris Chadwick, director at MDA Consulting Ltd, said: “Where much of the post-Grenfell reform agenda is procedural, the Building Safety Levy is a direct cash cost sitting on every qualifying scheme’s balance sheet. Calculated on measured floorspace and varying by local authority, its mechanics demand disciplined, stage-by-stage verification so costs are not overlooked.
In collaboration with LendInvest, MDA is sharing practical guidance to help lenders, developers, and surveyors successfully manage this shared financial risk from initial appraisal right through to final completion certification.”
