Updated BCRG quality declaration for Flint

25 July 2025

Good news: BCRG has approved our revised Flint P40 declaration. It now includes domestic hot water, important for NTA 8800 and BENG calculations.

Weheat Flint achieves strong results

NTA 8800 requires complete input for heating and domestic hot water systems. The new declaration gives designers and advisers validated efficiency figures for both M and L draw-off profiles, with high scores:

M draw-off profile – 3.026

L draw-off profile – 3.090

Why does this BCRG declaration matter?

BENG (Nearly Energy-Neutral Buildings) assesses energy demand, primary fossil energy use and renewable energy share. Domestic hot water plays an increasing role. The updated declaration:

• Gives Flint a complete, transparent position within BENG

• Helps advisers substantiate Flint in BENG calculations

• Strengthens our position in new-build projects.

This addition makes it easier for installers to use Flint in new builds meeting current regulations. Alongside technical performance, we provide documentation that makes a difference in tenders and design decisions.

The revised declaration is available in the BCRG database.

Updates for Sparrow and Blackbird

We naturally hope for equally strong results for our Sparrow and Blackbird and have not forgotten them! A Sparrow update follows in September, with Blackbird’s new declaration expected in mid-November.
