Is VURB more cost-effective than other compliance methods?

Yes, while the upfront modelling may cost more, VURB can significantly reduce material and construction costs.

Short answer

VURB can save money overall by avoiding over-specification of glazing, insulation or other materials.

Full answer

VURB allows builders and designers to meet NCC energy efficiency requirements without rigidly following Deemed-to-Satisfy (DTS) rules. This flexibility often results in lower overall build costs, especially in complex or bespoke designs.

Although the initial assessment may be more expensive than NatHERS or DTS, these costs are often offset by savings in construction, simpler specification and reduced need for redesigns.

Why this matters

Over-specification increases material costs and can complicate construction. VURB helps you meet compliance efficiently without compromising on design or budget.
