@StevieB - let's run the numbers. Suppose half the UK fleet (currently 37.5 million vehicles) had a battery pack. Suppose the packs need to be replaced every 10 years - that's 5,000 replacements a day. So I think we'd need more than 5 centres.
And as for 'a reasonable price' - I suppose it depends what you consider reasonable. I imagine you could get the labour costs down to well under £1,000, but a full pack currently costs £5,000 - £20,000 (or more for a high end EV). Anyone looking at a cost like that is going to want to think seriously about a replacement vehicle. The cost might come down by 10% or even 20% in the longer term, but there's no way it's going to reduce to a small fraction of the current level - the raw materials cost more than that.
Firstly, you're jumping the gun - you're saying half the fleet already. I'm saying on current levels and perhaps levels over the next 5 years. Half the UK fleet in 5 years still won't be full Hybrid or EV. So 2 to 5 centres will be fine, as the cost to train and kit them out will be high - 5 regional centres of maybe capacity of 10 bays will be enough to get started and not place a massive risk on the start-up. Battery pack will last longer than 10 years, and will go longer, but at a reduced rate. As far as i am aware, the batteries don't just give up, just lose their effectiveness - so even a waiting time of 3 months would be ok.
Economies of scale apply to the actual training and material price don't they - so as time goes on, costs will come down, as they have done already for Li-Ion tech. Just look at cordless power tools - battery packs have come down quite a lot over the years, as well as there size reducing, but amp/hr increasing.
Finally, you have to account on legislative behaviour of the government, which will probably drive manufacturers into offering competitive battery replacements - you can't crush the vehicles easily for scrap, as they'd have to be professionally removed and the pack recycled in accordance with WEEE guidelines. So they'll be a need for it anyway.
Once the mainstream centres spring up, eventually they'll sprout other smaller business etc who will do it too.
Also, look at depreciation rates of the Outlander - if you buy privately from new, you need to be keeping it several years to make it worth while. This is because there is a perception of risk in regards to the batteries. Make the batteries easy to swap out and replace for a reasonable cost, and then consumer confidence increases and values hold better.
My final point is, have you ever looked into the cost of a replacement engine for a car? Even a Ford Focus diesel engine will cost you several grand at dealer for a new replacement. So not much different from current batteries prices..... Look at BMW, MB and Audi, and you can double that price for an engine......
