Is planning permission required for house re-render?

tsolrm

The pebbledash is completely falling off now so we are changing it to a white render (silicon). The whole house will get a makeover. None of the houses on our street are white..

Do we need planning permission/signed off building regs? This is a detached house on a culdesac

Don't do it.  Replace with traditional pebbledash.

I have a house rendered with a silikon product and am having problems., I would not recommend it to anyone.

What problems are you having?

Pebbledash isn't an option it is too ugly

Basic rule of thumb - If you are replacing more than 25% of render, plaster, roof, or floor, building regulations kick in. This will require you to add insulation where technically possible and where the pay back (on energy savings) can be achieved within 15 years.

I agree, pebbledash, especially when it uses 10-20mm gravel, is piggin' ugly. Tyrolean finish isn't much better. I prefer a smooth finish, but it requires greater skill to avoid undulations. I'm fortunate that the render here is only on the upper half, and by doing only one wall at a time, I can avoid the 25% rule. Still insulating the walls internally...

How could they possibly know whether it was done 25% at a time or all in one go?

Because some nice neighbour will point it out to them 😉

It would appear, though not yet proven and not yet admitted by the manufacturer, that wind driven rain manages to get past the top Silikon top finish layer, soaks into the apparently porous base later, then when it freezes it expands and the bond fails and you have portions of the top coat not bonded to the bottom coat and blistering.

This is ongoing and not resolved and I would not recommend it to anyone.

Cement based pebbledash will last 50 years or more.

My neighbours have just covered their traditional brick built bungalow with white render , we live in a close with 8 other bungalows , it looks very odd

Think I must be a in a real minority to think no finish looks as good as a brick finish. The art of brickwork will die one day and everyone will be paying to remove render so they can expose the original brickwork. I'm convinced of that.

As for pebbledash, if its the original finish from when the house was built I'd probably restore, otherwise get rid and show off the brickwork.

Consider option of (non-flammable) external insulation , then render that.  Had 3 houses done with that at government expense, great improvement of energy costs, warmth and appearance.
