Can the water board turn up your water pressure?

Your water company is obliged, under the guaranteed standards scheme (GSS) to provide a maintain a minimum water pressure to your property. This is measured at the point that your own pipework starts, which should meet a 0.7 bar.

If this minimum pressure is not met you may be entitled to compensation.

There are however exceptions, where a drop in the water pressure wouldn't entitle you to compesation.

a payment has already been made to the same customer in respect of the same financial year;
it is impractical for the company to have identified the particular customer as being affected, and the customer has not made a claim within three months of the date of the latter occasion;
industrial action by the company's employees makes it impracticable to maintain the pressure standard;
the act or default of a person other than the company’s representative make it impracticable to maintain the pressure standard; or
the pressure falls below the minimum standard due to necessary works taking place or due to a drought
