Building Safety Levy deadline sharpens viability risk

Pick Everard is urging developers to account for the Building Safety Levy before its 1 October implementation date, warning that schemes still moving through technical design and building control preparation may face additional cost and programme pressure.

The levy will apply in England to certain building control applications and initial notices submitted on or after 1 October 2026 where works create new residential floorspace or new purpose-built student accommodation bedspaces. It is intended to raise funds for building safety remediation and will be administered through local authorities, with rates set by local authority area and calculated by chargeable floorspace.

Developments of 10 or more new dwellings, or 30 or more purpose-built student accommodation bedspaces, fall within the major residential development threshold, subject to exemptions and detailed charging rules. The levy must be paid before a completion certificate can be issued or before occupation, whichever comes earlier.

Pick Everard’s warning centres on submission readiness. Developers aiming to avoid exposure by submitting before 1 October may have less room than expected to complete technical design, coordinate consultants, resolve building control requirements, and lodge applications or initial notices. Where applications are refused or need resubmission, schemes may fall into the new charging regime even if earlier budgets assumed otherwise.

Higher-risk buildings face a further layer of complexity through Gateway 2. Where a scheme is already in the building safety approval process, refusal or delay can move cost exposure into a different position. The levy itself is only one part of the commercial pressure, as design revisions, procurement drift, consultant fees, funding assumptions, and contractor mobilisation can all be affected when compliance submissions slide.

Residential development is already adjusting to a heavier regulatory environment. The Future Homes and Buildings Standards have brought transitional dates, building-by-building commencement, solar requirements, ventilation, energy modelling, and M&E coordination into live project planning. The Building Safety Levy adds another cost-linked decision point, with technical readiness now tied directly to whether a scheme enters the charging regime.

Developers will need closer alignment between planning, design, building control, funding, and procurement. A planning consent alone will not determine levy exposure. The relevant trigger is tied to building control approval applications and initial notices, making technical design progress central to the financial position of a scheme. Phased developments, mixed-use buildings, multiple-client structures, and complex building control routes will require particular care.

There are exemptions, including certain social housing and supported housing arrangements, although the detail will need careful review. Mixed-use schemes and developments containing both exempt and chargeable floorspace may still carry exposure. Local authority rates also mean the viability effect will vary by location, with higher house-price areas generally facing higher charges.

Contract procurement could also shift as developers review budgets. Additional statutory cost may lead to changes in phasing, specifications, value engineering, risk allowances, or design freeze dates. Some schemes may accelerate submissions, while others may pause until the levy position is clearer. Those decisions can affect tender timing, pre-construction services, supply chain engagement, and starts on site.

Building safety, energy performance, carbon, product regulation, and payment reform are all adding more procedural and commercial weight before work reaches site. Developers treating these obligations as late-stage compliance tasks are likely to find that the cost lands earlier in the programme, with less room to recover lost time once technical design and building control decisions become linked to statutory charges.
