Consumer unit has 'shower' breaker?

Especially if you worry that the lost key represents a risk which requires the cylinders to be replaced....

That is what I was implying

No, not impossible

If the picture of the boiler posted is in the ops house then i doubt he will be getting a cylinder any time soon.

Even without seeing the boiler, my money was already on there being no cylinder. Unless the house is something special, then no modern developer will fit anything more than a combi - they'd have to find an extra square yard to house it, and that would mean making the house bigger than they can currently get away with. Not to mention the extra cost of installing it.
Mother's new house has a combi - and that's got two bathrooms, a downstairs loo, and the kitchen. I bet that would be fun with the three bedrooms actually used - and hence a likelihood of more than one facility getting used at a time.

Sadly, these guys claim to be able to copy Yale superior or Avocet ABS keys from just a photo of the key...

It's true that your standard high street key cutting shop/kiosk won't be able to though, granted.



edit:
They do ask for the code to make Ultion keys though....

Brisant who license Ultion keys are not too pleased about suppliers advertising the prices of the keys publicly.
