Solid wall insulation

The eco brigade have lost the plot on this one.

Until external cladding is fully funded by government the cost out ways the benefits.

Also a neighbour had this done about 6 years ago. Massive damp problems from it. (1950s house last of the single cavity housing stock)

The costs may outweigh the financial benefits but from an ecological point of view the costs are less relevant, a huge amount of the UK's housing stock is Victorian or older and of solid wall construction and external insulation represents a great way to massive improve the thermal performance of these buildings think of it as a gift to the next generation!

With all the damp it brings!

This is much less relevant than in the case of repointing, lime mortar allows the brick work to breath and dry out and is also softer so more likely to fail under freeze thaw thus protecting the bricks but with external render the brickwork is no longer exposed to weathering so should absorb significant quantities of moisture which need to breath, provided the house is adequately ventilated and extraction is present in the key rooms the internal walls shouldn't be absorbing large amounts of moisture either. so breathability of the mortar should be much much less important.

Living in an older house, and also having seen the catastrophic damage (Not in mine, but in others) that has resulted from interrupting the natural water flows in lime mortared houses.

I would be extremely cautious about doing anything to interrupt/interfere with the natural water flows/ventilation.

In any case, The issue about asking whether the salesman/contractor known about the difference between hydraulic/non-hydraulic lime still apples.

While this is not a specific issue for insulation, If they do not understand the question, they have no business working on an older building.

Really they do not.

Also factor in the simple fact that your house will be warmer..

We're looking at getting it done. Can't decide whether its better internally or externally. Our neighbours had it done and it certainly isn't in keeping with the houses external look.

15k buys a lot of electricity / gas....
 
Ask an estate agent if the 15K investment would be recovered on the house price. If not I wouldn't bother.

Maybe consider solar panels and some electric storage heaters.

I think you are failing to understand the nature of the moisture movement in a solid wall house and massively overstating the risks of causing damage even the pointing thing is hugely overstated it all depends on the type of bricks used in the construction. Yes the risk of causing damp problems needs to be evaluated just like when filling a cavity wall but your over exaggeration helps nobody.

What if it is your forever home? I plan to put an extension on my house next year knowing full well I won't recover all the cost in immediate increased value but I don't care as it will massively improve my standard of living and I have no intention of selling it!

We all to easily forget a house is supposed to be a place to life and enjoy life not a money making scheme!

I agree
 
From what I gather any rising damp problems need to be addressed before the insulation is installed.

But what other dampness issues can occur? It seems like you just need to ventilate enough and not do things like drying clothes indoors etc.
