The £4 Billion a year legalised theft!

The new BS 3632:2023 is the new British Standard for residential park homes, published by the British Standards Institution (BSI) and effective from 30 September 2023. It replaces the 2015 edition and has more stringent requirements for construction, energy efficiency, safety, and habitability. The following is a detailed explanation of its main requirements:

“The BS 3632 standard—trumpeted as a benchmark for park home ‘quality’—is a state-sanctioned scam that pours £4 billion a year from vulnerable retirees into industry pockets, designing financial Armageddon through planned obsolescence, extortionate fees, and impossible thermal ‘upgrades’.”

Please read!!!

1. Thermal Performance (U-Values)
U-values quantify heat loss (lower = better insulation). The 2023 standard tightens requirements:
Walls: Max 0.3 W/m²K (formerly 0.35).
Floors: Max 0.26 W/m²K (was 0.35), calculated as “exposed.”
Roofs: No change at 0.2 W/m²K.
Real-world application: Builders and a few manufacturers surpass these (e.g., walls at 0.27 W/m²K, roofs at 0.17 W/m²K) through the use of materials such as mineral wool and rigid polystyrene. (Polystyrene is flammable).


2. Construction Specifications

Walls
Insulation: Improved to avoid thermal bridging. Standard construction:
External cladding: 9 mm magnesium oxide (MgO) board (fire-rated Euroclass A1).
