You might hear people mentioning EN and BS standards to you.  all Willerby's holiday homes exceed the requirements to ensure you have a quality product. Here's a helpful guide to what it means.

EN 1647                                                                                                             

This is the European industry wide regulation for the manufacture of holiday homes.  The specification means that the home should be suitable for seasonal or holiday accommodation and not a s a permanent residence.    


BS 3632* (2005)

If you want to live in your holiday accommodation all year round (residential) then your home should be manufactured to this standard.  It means it is made more suitable for year-round living, including safety, acoustic and thermal insulation gas central heating, thermal performance double glazing and enhanced ventilation.

*BS 3632 (2005) standard is changing on 1st December 2016 and we will be making changes to our products in line with the new standard.


This isn't a standard, but we realised that often our customers didn't need everything prescribed in the residential standard but wanted to enjoy some of the upgraded benefits.  We created Therma-Max as a solution so people could enjoy the upgrade in insulation and thermal performance double glazing.
