When planning our Self Build Show Centre at St Neots in Cambridgeshire in the early nineties, we were already considering the question of ventilation and did in fact install HRV systems in each of the three houses hence the start of our relationship with Allergy Plus.
Neville Boon now Managing Director of the company was an early campaigner for the use of HRV systems has built up a wealth of knowledge and experience over the years. He now heads up this extremely successful company who are at the forefront of product development and a major name in the self-build market.
Another Allergy Plus product that appealed to us for our new show house was a Central Vacuum system. This system is so simple to install at first fix stage and when complete makes for an easier quieter life by just inserting the end of the lightweight hose into the nearest inlet point. With the power unit located in a utility room, under the stairs or in the garage, you can rely on a silent operation, good suction and with no dust bags to change a dust free environment.
Allergy Plus were the only choice for us in both of these areas, we have virtually grown together through the early days of self-build, and with many satisfied Potton clients installing Allergy Plus products over the years they know our designs well and have been instrumental in the planning and design of the right systems for our brand new “Wickhambrook” show house.
