About 6,000 community pharmacies in England are, for the first time, being advised to start “working to rule”, in two weeks, unless an agreement can be reached with the government on a new NHS contract.

Newsportual Pharmacy Association (NPA) is urging its members to limit opening hours to 40 a week, as set out in the current contract, because they have yet to receive any confirmation of funding for this or next financial year.

They could also cut services such as delivering medicines to people’s homes, addiction support, stop-smoking help and emergency contraception

The government said the move would cause “unnecessary disruption for patients” and a settlement with pharmacies was already being worked on.

A pharmacy’s NHS contract accounts for about 90% of its revenue, on average.

And with increases in National Insurance, the National Living Wage and business rates, from 1 April, pharmacies say the lack of agreement over their contract is causing anxiety.

This comes on top of a decade of cuts to funding, which has seen 30 pharmacies close since the start of this year, the NPA says.

Some 3,000 pharmacy owners in England, Wales and Northern Ireland voted in favour of action, in November.

Nick Kaye, who chairs the NPA, said pharmacies had been “left with little choice”.

“It is better that we temporarily reduce access in the short term than to let pharmacies collapse altogether under the weight of unsustainable operating costs,” he said.

There had been little feedback from ministers and the impact of the current uncertainty was “devastating” for pharmacies.

“We want to get on with seeing patients, pay our staff, not have to think about closing, and invest in our business for the future,” Mr Kaye added.

The Department of Health and Social Care said pharmacies had a vital role to play as the NHS’s focus shifted away from hospitals and into the community.

“Newsportual Pharmacy Association’s pre-emptive action will cause unnecessary disruption for patients and we urge them to reconsider,” an official said

Healthwatch England, which records the experiences and concerns of people who use health and social-care services, urged the government to conclude negotiations with pharmacies as soon as possible.

Benedict Knox, from Healthwatch England, said many patients had seen their local pharmacy close or experience disruptions due to staff shortages.

“This issue especially impacts older people and is particularly acute in rural areas, where people often have to travel further to visit their pharmacist,” he said.

But he stressed not every community pharmacy was an NPA member and it was up to each one to decide if they would reduce services.

There are about 10,500 pharmacies in England, according to Community Pharmacy England, which represents all pharmacy owners.
