Over three-quarters of respondents (78%) said access to paid leave would better help them balance their working responsibilities with caring for a family member, friend or neighbour.

Helen Walker, chief executive of Carers UK, said: ‘Introducing paid carer's leave would particularly benefit those on low pay – as often they cannot afford to take unpaid leave from work – and women who provide the bulk of unpaid care and are more likely to be disadvantaged by this.'

The new report is supported by TSB Bank for Carers Rights Day (21 November 21).

Ariam Enraght-Moony, chief people officer, TSB, said: ‘Having offered two weeks of paid carer's leave a year to TSB colleagues for over four years, we have seen first-hand the positive impact it has on our colleagues and the lives of those they care for. We would encourage all big businesses to introduce this vital support.'

Liberal Democrat leader Ed Davey said: ‘I have been a carer most of my life, first for my mum when I was young and now for my severely disabled son John, so I know how challenging it can be, but also how rewarding.

‘These findings show just how much carers contribute to our society, but also how hard it is for carers to get the support they need.'

A Government spokesperson said: ‘We will examine the feasibility of introducing paid carers' leave, considering its impact on small employers.

‘Helping carers is an important part of our plans to modernise the world of work, ensuring they can enjoy a good job and contribute their skills alongside their valuable role as carers.'
