Abolishing 213 smaller councils in England and replacing them with 25 new native authorities might perchance well also place virtually £3bn over five years, a file says.
The file for the County Councils Community says one physique in every situation would lower complexity and offers communities a single unified train.
On the other hand, others argue bigger councils are unwieldy and undemocratic.
The federal government is anticipated to publish its delight in proposals on overhauling native government within the autumn.
Plans might perchance well also embody scrapping district and county councils in England in favour of fewer, better authorities which regulate all products and services in their situation.
County councils, including Surrey, North Yorkshire and Leicestershire, delight in developed or are already rising plans to interchange county and district councils in their situation with a single physique.
In most of England, native government operates underneath a two-tier system, with both a county council and a district council providing products and services.
County councils’ duties embody training, social products and services and raze disposal.
Every county is subdivided into areas represented by district councils. These councils are accountable for rubbish sequence, housing and planning.
Some ingredients of the country – in overall cities or better cities – are governed by unitary authorities which provide all native government products and services.
The file implemented by PriceWaterhouseCoopers argues that merging district and county councils in a mid-sized county situation into single organisation might perchance well also place £126m over five years and £2.94bn nationally.
But it no doubt additionally warns that rising two unitary authorities in one county would lower the financial savings by two thirds.
Cllr David Williams, chairman of the County Councils Community, who commissioned the file, said there was as soon as a “compelling” financial case for rising extra unitary authorities.
Speaking to the BBC, he said that in his county of Hertfordshire there are 11 native authorities. “That intention there are 11 chief executives, 526 councillors, 10 planning groups – so there is an dreadful lot of complexity, and there is pretty tons of price.”
The network additionally infamous “hypothesis” that the federal government might perchance well also quandary a inhabitants restrict of 600,000 folks for every unitary authority and argued that “splitting ancient counties” would make “a worse deal for native taxpayers”.
It additionally suggested that establishing better than one unitary authority in a county would imply splitting up kid’s social products and services and grownup social care departments, risking instability.
Some council leaders strongly oppose plans to abolish smaller councils.
Sharon Taylor, Labour leader of Stevenage Council, knowledgeable the BBC her native county Hertfordshire, with its inhabitants of spherical 1.3 million, is “appropriate too huge” to be represented by one single council.
“That is centralising native products and services which looks fully sinister,” she said, including that Britain has the “least illustration at native stage of anyplace in Europe already”.
“That exact democratic train that folks delight in at native stage is de facto principal to them,” she said.
Native government reform is no straightforward job.
Whereas the leaders of better county councils are advocating a shift to unitary authorities, several smaller district council leaders are in opposition to the premise.
This comprises Conservative council leaders, which might perchance well also showcase to be a political headache for presidency.
Despite that, ministers delight in signalled that they’re in all probability to point out fewer, better authorities – and perchance extra elected mayors – after they publish a paper on devolving vitality within the autumn.
Giving councils extra clout to assemble choices on behalf of their native areas is, the federal government says, portion of its are trying and ‘stage up the country’.
But past any argument about reforming constructions sits the inquire finance. Councils in England delight in long argued budgets are so stretched that some products and services might perchance well also objective change into unsustainable.
The federal government has made extra cash obtainable one day of the Covid pandemic and says or no longer it is given councils extra spending vitality.
But for social care products and services in explicit the stress is acute, and the correct technique to reform – and fund – that struggling sector aloof looks some distance from settled.
