The chancellor has given her backing to an expansion plan for the corridor connecting Oxford, Milton Keynes and Cambridge, including thousands of homes, which the previous government dropped. Joey Gardiner asks what hope the industry can have that Labour can stay the course

Oxford North 1

Oxford North is an innovation district off the A40 with accompanying canalside residential development. The first phase is due to open this year 

It did not take long for the backlash to begin. Even before chancellor Rachel Reeves had stood up to deliver the speech at which she announced her backing for a 鈥済rowth corridor鈥 between Oxford and Cambridge, the Daily Telegraph was already reporting the fears of residents in the corridor that the plans will 鈥渨ipe us out鈥. And the Daily Mail has already branded one village for proposed development, Tempsford, as 鈥淪tarmer鈥檚 village of the damned鈥.

Reeves her decision to push for growth along the arc linking Oxford, Milton Keynes and Cambridge could gift the UK a 拢78bn boost to economic output in the next decade alone, through fully harnessing the potential of the hi-tech and life sciences industries springing out of the famous university cities.

The chancellor, desperate for a positive economic vision to lift businesses鈥 eyes from the grim present, coupled her support for the growth corridor with a string of announcements designed to instill confidence in the idea. She confirmed funding for completing the 拢7bn East-West Rail project, the lifting of Environment Agency objections to a major housing scheme around Cambridge, the setting up of a growth vehicle in the city of Oxford, her backing for key reservoir projects to solve water capacity constraints, and the appointment of Sir Patrick Vallance as growth corridor champion in charge of delivering the vision.

But it has escaped the attention of few of those living and working in the areas affected that the 鈥済rowth corridor鈥 is actually a re-working of the Oxford-Cambridge Arc plan promoted by the previous Conservative government 鈥 a policy which Reeve鈥檚 predecessor, Michael Gove, dropped in 2022 due to fierce local opposition. This had proposed one million new homes across the area by 2050, built at double the rate previously expected.

Paul Miner, head of policy at countryside charity the CPRE, says the body will continue to resist it if similar growth is proposed. 鈥淭his is a disproportionate amount of growth just in that corridor,鈥 he says. 鈥淭he sheer extent of it has an impact on nature conservation, on farmland and historic landscapes. There needs to be a proper balance across the country.鈥

So, despite this continued resistance, what is the likelihood that the government will stay the course, and things might be different this time around?

Unpopular plan

The original Oxford-Cambridge Arc plan was set in motion by the 2016 budget of then chancellor George Osborne, who asked the newly formed National Infrastructure Commission to investigate how to maximise the area鈥檚 potential. The plan the NIC came back with 鈥 which relied on the completion of East-West Rail and a huge dual carriageway project through Oxfordshire, 鈥渃ity-scale鈥 new towns and a million homes (see panel for detail) 鈥 was initially backed enthusiastically by the government, which described it as a 鈥渟ignificant opportunity for transformational growth鈥, and drew up proposals for a joint spatial plan covering the whole region.

However, as time went on the arc lost support as the strength of opposition on the ground became apparent. Campaigners against the 鈥渆xpressway鈥 linking Oxford with Milton Keynes said constructing the road would free developers to build the 鈥渕illion鈥 homes called for by the NIC.

The project was put 鈥渦nder review鈥 weeks before the 2019 general election, before being cancelled altogether in 2021. Local authorities, starting with Buckinghamshire, began to withdraw support for the whole idea of a regional plan, until in June 2022 then communities secretary Gove revealed the government was no longer working on a regional plan, and had stopped centrally promoting the idea of the arc full stop.

Independent planning consultant Catriona Riddell, who has advised Labour on its strategic planning reforms, says: 鈥淭he thing that killed the arc plan was the call for a million new homes 鈥 it just galvanised the opposition.鈥

Likewise, Heather Pugh, partner at masterplanning firm David Lock Associates, based in the heart of the growth corridor in Milton Keynes, says the original plan鈥檚 focus on housing proved 鈥渢oxic鈥. 鈥淚t fell down due to the one million new homes number. It was just a toxic headline.

鈥淭he reality was that the homes are needed either way. The arc plan was just going to make sure they were better connected.鈥

The NIC鈥檚 plan for the Oxford-Cambridge Arc

The National Infrastructure Commission was asked to look at the case for establishing a growth 鈥渁rc鈥 linking Oxford, Milton Keynes and Cambridge. Its 2017 report said it should be a 鈥渘ational priority鈥, and that its economic development was being hampered by a 鈥渃hronic undersupply鈥 of homes. It proposed:

  • 精东影视 both the East-West Rail line and an 鈥渆xpressway鈥 road project 鈥渁s quickly as possible鈥
  • Doubling the delivery rate for housing across the Arc, with a target of one million homes by 2050
  • Establishing a pan-arc spatial planning framework to deliver the necessary development
  • A programme of new settlements from smaller-scale garden towns of around 10,000 homes through to new city-scale developments of up to 150,000 homes, located between Oxford and Milton Keynes, and between Bedford and Cambridge.

Huge support

But, despite the fading political support for the arc, the proposal was always viewed positively by businesses and the development industry. The Oxford-Cambridge Supercluster group, set up to advocate for the region and made up primarily of universities and major employers, says that taking a pro-active approach to the opportunity in the corridor could double projected growth, driving a 拢51bn per annum increase in economic output above what would otherwise occur by 2050, and the creation of an extra 300,000 jobs.

The group says this potential comes from the fact the area, with its world-class universities, already excels when it comes to the number of high-skilled workers, high-value science and technology start-ups, and worker output.

Andy Hill, chief executive of housebuilder Hill Group, says the level of demand for commercial space cannot be met unless something changes. 鈥淭hey鈥檙e inundated. There鈥檚 huge demand around life sciences, robotics,鈥 he says.

鈥淚 think the government has woken up to the fact the real choice for these investors is, if they can鈥檛 find the space close to where they want it, they won鈥檛 just go further away, they鈥檒l go to another country.鈥

Paul Brocklehurst, chair of industry body the Land, Planning and Development Federation, whose members are commonly land promoters, says he is 鈥渁ll behind鈥 the plan, which also provides a big opportunity. 鈥淚f it鈥檚 done in the right way, it is absolutely the right thing to be doing,鈥 he says. 鈥淲e have members who were heartbroken when it failed first time around.鈥

And while Reeves was careful to frame her adoption of the growth corridor as primarily an economic strategy designed to attract businesses to locate and expand in the region, neither did she shy away from the implications for housing delivery. The chancellor said the New Towns Task Force was considering 18 submissions for settlements to be built along the route of the East-West Rail line, which she confirmed will be built in full.

鈥淧olitically this site wasn鈥檛 acceptable before. But I think people are waking up that we need to build homes where people want them. The chances of schemes happening will increase.鈥

Andy Hill, chief executive, Hill Group

David Lock Associate鈥檚 Pugh is among many local observers who now expect the government to identify sites for new towns in the corridor, and says the commitment from government means that 鈥済rowth at scale is back on the table鈥. The village of Tempsford, where the East-West Rail Company has committed to building a station on the intersection with the east coast mainline, and where developer Urban & Civic is promoting a , is clearly already the subject of speculation that it could ultimately be the location of a new town (see panel for detail).

Whether or not that plan is brought forward, developers say the government鈥檚 commitment to the project makes a difference in their expectations of sites coming forward. Hill believes that sites he owns in the corridor 鈥 including a 600-acre farm site he has options on close to Cambridge鈥檚 hi-tech clusters 鈥 have a better chance of securing approval with the government promoting the arc.

鈥淧olitically this site wasn鈥檛 acceptable before. But I think people are waking up that we need to build homes where people want them. The chances of schemes happening will increase.鈥

Case study: A new town for Tempsford?

The village of Tempsford, which sits on the bisection of the east coast main line and the proposed East-West Rail line, has long been speculated on as a site for a new town, with confirmation that it will get a station on the east-west line intensifying that speculation. is promoting 2,100 acres in the area to build up to 7,000 homes, while architect has also drawn up plans for a Tempsford Market Town for an unknown private client.

Last year think tank UK Day One proposed building a at the location, 鈥渓arger than Oxford or Cambridge鈥, which it said could be a 鈥渕ajor employment centre鈥 for life sciences.

Paul Campbell, chief executive of land promoter Richborough, says he admires the ambition, takes the growth corridor 鈥渟eriously鈥, and that government support for the corridor 鈥渨ill change what we do鈥.

鈥淔or this to feature so highly in their growth plans,鈥 he says, 鈥渋t鈥檚 a factor we鈥檒l take into account when we now look at opportunities.鈥

Blue-chip commercial developer British Land, which has significant investments in both Cambridge and Oxford, is also backing the plans. The firm has just put 拢150m into its Peterhouse Technology Park to build a new headquarters for chip maker Arm, and is considering promoting a site near Trumpington under the government鈥檚 new grey belt policy.

Gareth Roberts, head of development for science & technology, at the firm, says the corridor is a big opportunity, particularly in terms of helping to tackle the infrastructure constraints that have bedevilled major schemes in both cities. 鈥淎ll the signs we鈥檙e seeing are positive,鈥 he says. 鈥淭he last nine months have seen lots of small changes which are quite joined up.鈥

Confidence

This, Roberts says, is adding up to a sense of confidence that the project has a better chance this time around. 鈥淚t looks like they鈥檙e tilting more towards listening to business and prioritising growth. I hope they manage to stay the course,鈥 he adds.

One of the reasons giving some cause for optimism so far is the broad positivity across local government in response to Reeves鈥 announcement. Where councillors in south Oxfordshire, , ended up branding the previous iteration of the arc an 鈥渁rbitrary construct鈥 designed to drive 鈥渆xcessive growth鈥, so far any opposition has been muted, while key authorities, such as Oxford and Cambridge city councils, have come out in support. South Cambridgeshire council told 精东影视 it was having a 鈥渃onstructive鈥 dialogue around growth.

Planning consultant Peter Studdert, a former director of planning at Cambridge City Council, says the new attitude is in part because authorities such as Cambridge have realised that, by working with government, there is the potential to secure big benefits through the funding and planning powers likely to be made available to a new breed of development corporations.

Cambridge City Council has come out in support of a development corporation 

The government has proposed using development corporations 鈥 which are bodies set up with statutory powers and a mandate to deliver development in a defined area 鈥 to buy up land at low cost, thereby allowing projects to deliver high levels of infrastructure and affordable housing. The idea is that development corporations would make use of enhanced compulsory purchase powers due to be enacted in the forthcoming Planning and Infrastructure Bill.

Studdert says it is significant that Cambridge鈥檚 council leader Mike Davey, plus the Cambridge and Peterborough Combined Authority mayor Nik Johnson, were both signatories to an open letter to the government which called for a new development corporation in the area. 鈥淭here鈥檚 now an acceptance that this, along with grey belt, could pay for very high levels of affordable housing. It could be an acceptable mechanism for growth that maximises social benefits,鈥 Studdert says.

As ever, of course, incentives are both carrot and stick. Pugh says: 鈥淭here鈥檚 a recognition with the devolution agenda that local authorities can work together, and have more in common than divides them.

鈥淏ut also I think they realise they are not going to deliver for local people if they go it alone. If they are not inside the tent, they could be ostracised.鈥

Chris Pattison, head of the Oxford office at planning consultant Bidwells, which is a member of the supercluster group, says the government鈥檚 devolution agenda, which will see smaller local authorities merge into unitary councils, and neighbouring authorities or combined authority areas collaborate on 鈥渟trategic鈥 development plans is another positive step. He says: 鈥淩ight now we鈥檝e got 10 district authorities, eight unitaries, two county councils and a combined authority in the arc. We鈥檝e asked our smallest political entities to deliver housing growth through a voluntary co-operation process.

鈥淚nevitably that has failed,鈥 he says. 鈥淭here鈥檚 a hope that now we can begin to take a more strategic view.鈥

In addition, he says, the appointment of Vallance is a sign that delivery is being taken seriously. 鈥淭he government knows it needs to pull all the strands together and that鈥檚 where Vallance will come in,鈥 he says, adding that he understands the former chief medical officer during the covid crisis will operate with the benefit of a pan-department team of officials, with a commitment to appoint a director of the growth corridor within Whitehall.

Realism

But of course, despite the optimism, huge obstacles to delivering a boost to growth across the corridor remain. Not least because the local government restructure and creation of strategic plans that Pattison mentions will not happen overnight.

鈥淚n the real world, delivering this is going to take a revolution in regional planning,鈥 says Richborough鈥檚 Campbell. 鈥淟ast time it was just dropped as soon as it got too political, so we have a healthy level of cynicism.

鈥淚t鈥檚 got to go through numerous local election cycles. There will be constant bumps in the roads.鈥

There is also no prospect of joining up the planning efforts of the region鈥檚 authorities into a single coherent plan, as was proposed last time, says Riddell. Instead, she says the region will likely be split between three combined authorities 鈥 one around Oxfordshire and the Thames Valley, one for the south Midlands, and the already existing Cambridgeshire and Peterborough authority 鈥 each with their own plan.

Paul Campbell, chief executive, Richborough

鈥淣o one is mentioning a strategic framework for the arc,鈥 Riddell says, something Pattison says is regrettable but can be worked around.

More concerning are the major remaining infrastructure problems constraining development across the region. While Reeves has said she backs proposals for two new reservoirs to tackle water shortages, neither of these has planning permission and it is not clear when they will be delivered.

British Land鈥檚 Roberts says that in Oxford difficulties with getting sewage infrastructure have the potential to hold up projects, and that both cities suffer from grid infrastructure challenges.

Meanwhile, the vital transport infrastructure issues have not been solved. While the eastern leg of East-West Rail now has confirmed backing, it does not even have a confirmed route, and is a minimum of a decade away from being delivered.

The East-West Rail line to connect Oxford with Cambridge is being delivered in three stages. Services between Oxford and Bedford are due to start this year

Meanwhile, the completed western leg from Oxford to Bedford, on which services are due to start this year, has done little to drive growth in employment or housing accommodation, with growth remaining highly controversial in Buckinghamshire. Pugh says: 鈥淭here鈥檚 no growth at the moment planned off the back of them [East-West Rail services]. That thinking hasn鈥檛 been done.鈥

Likewise, the formerly pivotal expressway project does not appear to be back on the table. 鈥淣o one is talking about the expressway,鈥 says Riddell.

Given all this, many see the prime focus on growth as at the eastern end of the corridor 鈥 despite the fact water shortages remain acute in the area, and East-West Rail will not reach this part until the mid-2030s at the earliest. Pugh says: 鈥淐ambridge is really good at thinking about strategic growth, whereas at the Oxford end, the feeling seems to be that it鈥檚 more about extending existing places.鈥

The reality is that there is little that can actually be delivered against a plan within a single parliament 鈥 which, given the volatile nature of current politics, means uncertainty will inevitably continue. Opposition may also grow as campaigners organise themselves to face the new reality.

However, the changing mindset at a local level means that many developers remain optimistic. 鈥淚f you look at what鈥檚 happened, despite the government withdrawing it鈥檚 support in 2022,鈥 says Bidwells鈥 Pattison, 鈥渢he trajectory of the arc has only gone up and up.鈥

Hill says the discussion on the ground has fundamentally changed. 鈥淚 think people have grasped the need,鈥 he adds. Others will be hoping that he is right.
