THE SHORT ANSWER
Statutory nuisance covers any time of day.
Warning notices cover noise above a set level from 11pm to 7am.

Based on Defra guidance on how councils deal with noise complaints in England. Councils decide their own level of service, such as night-time cover. Not legal advice.
FOUR STEPS FOR A NOISE PROBLEM
GOV.UK's guide to neighbour disputes sets out an order to try. It usually works best to start small.

Explain the problem calmly and stick to the facts. If others are affected, involve them too.
If your neighbour rents, you can complain to their landlord, housing association or the council.
An impartial mediator helps both sides agree. It's confidential and usually quicker and cheaper than court.
For a statutory nuisance such as loud music or barking dogs, the council has a duty to investigate.
TWO NUMBERS WORTH KNOWING
The permitted level at night in a quiet area,
and the fixed penalty for a home that ignores a warning.
34 dBA
Night noise limit when background is 24 dBA or less
Where the underlying noise is louder than 24 dBA, the limit is 10 dBA above it. The level is measured from inside the dwelling of the person who complained.
PERMITTED LEVEL · DEFRA
£110
Fine for a home ignoring a warning notice
Paid within 14 days instead of prosecution. For licensed premises the fixed penalty is £500. If convicted, a home faces a fine of up to £1,000.
FIXED PENALTY · DEFRA
A warning notice must give at least 10 minutes to bring the noise down, and the period must end by 7am.
AFTER AN ABATEMENT NOTICE
An abatement notice requires whoever is responsible to stop or restrict the noise. The council can delay serving it for up to 7 days while it tries to get the noise stopped informally.
GOV.UK says breaking an abatement order about noise from a home can lead to a fine of up to £5,000, and up to £20,000 for noise from a factory or business.

Questions
For council warning notices, night hours run from 11pm to 7am. Councils can still investigate statutory nuisance at any time of day or night.
The permitted level, measured from inside the complainant's home, is 34 dBA where the background is 24 dBA or less, or 10 dBA above the background if it is louder.
The council can give a fixed penalty of up to £110 for a home or £500 for licensed premises, prosecute, or remove noise-making equipment such as loudspeakers.
Yes. If a key holder can't be reached and the alarm has sounded for 20 minutes continuously or 1 hour intermittently, officers can enter without force to silence it. Using force needs a warrant.
GOV.UK advises trying to solve the problem by talking to your neighbour or through mediation before contacting the council.
