Yes there were lots of others, I'll find a few (but it's late, I can't remember what I googled and I think DS is breaking out in chicken pox spots 
so my focus on this has gone a bit.)
There is this one for Glasgow.
Or this one for Kingston on Thames. They say "The times agreed may vary according to each case however for general guidance, noisy activities (such as those described above) should be restricted to the following hours:
Saturday 9am to 5pm, Sunday, including Bank Holidays 10am to 2pm, Weekdays 8am to 7pm"
Or this one from Thurock Council (I have no idea where Thurock is) but they suggest DIY takes place from Monday to Friday - 9am to 7pm, Saturday - 9am to 5pm, Sunday or Bank Holidays - No noisy work and say that "In particular, DIY noise must not interfere with those attempting to sleep at night. This is especially important if young children are living next-door" which the OP has.
This one from West Berkshire is a little more flexible (and a bit Mumsnet) with their suggestion that "It is not unreasonable for people to undertake DIY works unless they are occurring late at night or early in the morning (i.e. after 9.00 p.m. or before 8.00 a.m.). Should noisy works (e.g. hammering, using power tools) occur outside of these times, the resulting noise may constitute a statutory nuisance."
The one for Craven District Council in the Yorkshire Dales has set times listed. Weekdays: 9am to 7pm, Saturdays: 9am to 5pm, Sundays: 10am to 2pm.
Some of them are a little more vague but lots did have specific times listed. I suppose it depends where you are in the UK, and the easiest thing to do might be to email your own council and ask if they don't have it on the website.
