I need to purchase a electric scale inhibitor.

I suggest you don't.

They seem to range in price, from £35 at toolstation to over £75 for
those advertised on TV.

I can only assume they have different power outputs as a reason for the
price differences.

They have various, mainly cosmetic, differences and varying wildly
inaccurate descriptions of how they are supposed to work. None of
these affect their complete lack of effectiveness.

Can anyone recomend a fair price unit that will work.

Not really as none of them work. If you really want to convince
yourself buy the cheapest which doesn't require installation and
comes with a 12 month "money back" guarantee. Get it from a major
retailer - somewhere like Homebase - and get it in writing that you
can have a full refund when you find it is useless. Make a careful
note of the convoluted terms of the guarantee and mark on the
calendar when you must return it. The marketing of these devices
relies upon people forgetting to claim their money back months after
buying them and finding they don't work.
