I ordered a Potterton Progrmmer and it arrived on time without any problems,
which I expected it to do. Buying 'on line' is easy, fast and reliable and 'Heating
Controls On Line' met those essential elements,I will use them again, thank you
Got what I wanted quickly
Good service. Item ordered on Sat, received on Tues. All present and correct.
