Richard Lloyd, Executive Director at Which? told ITV News that the report is: "a damning indictment of how competition is letting customers down. It's proved that the politicians are wrong to hope that competition will fix the massive problems in the energy market."
Consumer group Which? said supermarket bosses should "hang their heads in shame" after the level of campylobacter contaminated chickens was revealed by the FSA.
The most common complaint about nuisance neighbours is loud voices and arguing, according to Which?
The watchdog's poll found:
- 41% were annoyed by loud voices and arguing coming from next door.
- 29% of adults were aggravated by loud music and noisy TVs.
- 27% were fed-up of doors slamming.
- Some 23% were annoyed by neighbours stomping around.
- And noise from pets upset 21% of the people quizzed by Which?
More than one in four people have had their life made a misery by an anti-social neighbour in the past year, a consumer watchdog has found.
A poll for Which? found 27% of UK adults have struggled with issues like loud voices, arguing and aggressive pets.
The watchdog found that young people were more likely to suffer from a nuisance neighbour, with 33% of 18 to 24-year-olds having experienced a problem, compared with 17% of those aged 65 and over.
Which? executive director Richard Lloyd said: "Having a nuisance neighbour can be a real problem ... There are a number of ways you can complain and resolve a dispute, which is why we have produced a free guide to help."
Sunscreen manufacturers need to do more to make sure their product provides the level of protection it claims, as skin cancer rates rise, a consumer watchdog has said.
Which? executive director Richard Lloyd explained:
Three popular screens have failed an independent protection test and could not provided the protection from damaging UV rays they claimed to offer, a consumer watchdog found.
Which? tested Piz Buin Ultra Light Dry Touch Sun Fluid SPF30 150ml, Malibu Protective Lotion SPF30 200ml and Hawaiian Tropic Satin Protection Ultra Radiance Sun Lotion SPF30 200ml, which all claimed to be SPF 30.
They all had lower results than SPF 25.
The consumer group has branded the creams as "don't buys" in its investigation, which used British Standard tests to check 15 products with an SPF (sun protection factor) of 30 - a bestseller in the UK.
A third of people who used a public service in the last year and were dissatisfied with it did not complain, with the most common reason being "it would not be worth the effort", according to a Which? survey.
The poll found 34% of people who experienced a problem with public services did not complain.
One third of those people said it was because they did not know who to complain to, while a further 39% said they did not feel it was worth the effort.
Which? executive director Richard Lloyd said: "Barriers to giving feedback must be removed if public services are to deliver the high standards that we all expect.
"We want to see a shake up of the way complaints are handled, to give people the confidence that their complaints count and will trigger action."
In response to a Which? study that concluded it is "virtually impossible" for people to calculate and compare current account costs, the Government said it is "clear" that customers must have easy access to clear information on overdraft charges.
It confirmed that a "more robust regulatory system" will be in place soon.
Baffling terms used by current account providers to describe unauthorised overdraft charges include "informal","unplanned", "unarranged" and "unapproved", Which? found.
Current account providers are using vague language and baffling charges structures making it very difficult to calculate the cost of slipping into an unauthorised overdraft, research from consumer watchdog Which? has found.
The consumer group used 18 volunteers, including a principal inspector of taxes and a retired headteacher, to work out what the cost of an impromptu overdraft would be using a mock statement and charging structures on the bank's website.
The volunteers got just 10 out of 72 calculations correct between them, with the tax inspector getting just one of his four calculations right and the former headteacher getting them all wrong.
