Hi Edd, I just googled PH test reviews and the one that stood out was Luster Leaf 1612. It's American so most reviews were on Amazon US but they were consistently good, this one impressed me,
"I'm re-ordering this pH testing kit,because I've used up the pH tests of the first kit I bought. It's excellent. Contrary to what one other reviewer has said, it's extremely accurate. I had my pH tests repeated by the local Agway farm store manager and also by the County (Agricultural) Cooperative Extension agent. Both of their pH tests were exactly the same as those I got using the Luster Leaf pH tests.
Instructions are very clear and simple. The test itself takes only about 3 to 5 minutes to do. (Though if you go on to test N, P, and K with Luster Leaf's test kit for those elements, those tests will take a few hours - hands on time for those other tests is still only a few minutes though)."
I did find it on Amazon UK, £6.43 for ten.
