One great fix for low water pressure in boilers is to add more water as follows:

  2. Ensure the filling loop is securely attached and open the valves at either end.
  3. This will allow water to flood your system.
  4. Once the boiler gauge reads about 1.5 bar, close the valves.
  5. You can then turn your boiler back on.
  6. Top tip: Make sure to give your boiler time to heat up before you try to run a bath or shower.

If you are not experienced with boilers, please do not fiddle, instead, contact a professional.
