NHBC Warranty & Low Water Pressure

Albermarle

There is only a statutory requirement for the water supply authority to provide a minimum water supply pressure of 0.8 bar at the entry point to your house

I always thought it was 1 bar, so I googled it. According to OFWAT ( an a couple of other sites I looked at, the minimum guaranteed pressure is 0.7 bar. Although the target minimum for most water companies is 1 Bar.

It's not a fault or anything that is broken, and definitely not a NHBC fault. It is a government decision to reduce water usage, given how vulnerable our water supplies are.

Hot water temperature to baths is limited to prevent scalding to vulnerable people.

But I guess people know better, and just remove all safety devices and environmental features themselves. 

Honestly if my pressure was reduced to 1 bar when it's coming in at 4, then safety and environmental devices be damned. You should be able to shower at a decent pressure and if not I don't blame anyone for removing these devices.

 We are neither old nor vulnerable and know what temperature we like our showers to be. 

 Taking half an hour to run a bath because the water pressure is too low to take a shower is not acceptable.
