    I have had no problems using tap water in California where the water is hard or Virginia where the water is much softer.

    I'm on a well and use distilled water to mix my chemistry and for a final rinse. Here I can get a gallon in my local supermarket that claims to be steam distilled for $0.79. Since I do mostly 120 films one-shot in HC110 and infrequent printing, the cost isn't important enough to experiment too much. Interestingly, I used to see a lot of rusty iron deposits in the toilet tank and such here, but since replacing the well pump a year ago, which replaced the iron well pipe with plastic, a lot of that has disappeared. Might have wished I'd done it sooner, except for the $3K!

    For most developers it doesn't matter.

    However, distilled water can be a must with most water systems when using highly dilute developers.

    If you have already spent 10 quid on the film and developer then a shilling more for a cup of DI water isn't very significant.

    For me I find that the key is the same water rather than any given type. I have water with a Ph of 5, yes acid flows from my taps and I have become quite a good plumber because of it, and it has a lot of deposits in it. I was using distiled water only for some time and then it was mentioned that in the early days of photography they probably used whatever was available so I gave it a shot and used my tap water. Well, I used the same process with no adjustments and it works just fine for me. I did once use distilled water as stop bath with my lousy water in the dev and fix and I got the dreaded purple Kodak negatives, that was the last time I did that, no more mix and match for me.

    For important developer used for multiple times or stored long term, like XTOL or Diafine, I like to use distilled water. For one time use chemicals I tend to use just reverse osmosis filtered water.

    The well water without filtering it is about 200 ppm (parts per million?). With reverse osmosis filtered it is about or less than 10 ppm. The tap water from some municiples varies from 50ppm to 150ppm.

    I am not sure about affect of hard water. I believe the water from reverse osmosis is still hard water if the source water is hard water. So using distilled water is better.

    For distilled water I believe the cost is less than a quarter per gallon of home generated distilled water. I guess it is 1 or 2 dollars per gallon for distilled water from supermarket.

    I use it for developer and final rinse in my b/w and c-41 just to be sure.
    I think Halfords call it Battery Water

    I use it for a my final rinse with sheet film - dries with almost not residue

    As for the OP - yes I would use Halfords Battery Water for this application.

    Standard developers are buffered to work equally with the wide variety of water types available world wide.

    Specialist developers like this one are probably are not buffered - hence the note for Distilled Water
