UK Health Security Agency: Porton Down

Motion made, and Question proposed, That this House do now adjourn.—(Sir Nicholas Dakin.)

I am extremely grateful for the opportunity to bring the future of the UK Health Security Agency campus at Porton Down, in my Salisbury constituency, before the House again this evening. I say “again” because 15 years ago, on 22 June 2010, as an eager, newly elected, young MP, I raised the uncertain future of the institution in my first ever Adjournment debate. I did so again on 11 September 2013 and again on 24 June 2015, at the start of my second term as Salisbury’s MP.

In one sense, a lot has happened in the past 15 years, but sadly, in another sense, nothing has happened. The project to relocate to Harlow, in Essex, is apparently no closer to completion, but neither have the highly skilled workers at Porton Down been given any assurances that they can stay put. I know that this matter will concern you, Madam Deputy Speaker, given that a number of residents in your constituency of Romsey and Southampton North, which is adjacent to my constituency, will be working at Porton.

As the Secretary of State for Health and Social Care said in response to my oral question on 13 March, two months ago, this

“has been running around the system so long that is now used in a case study for senior civil servant recruitment.”—[Official Report, 13 March 2025; Vol. 763, c. 1295.]

As the House of Commons Library said in a note to me on 22 January this year,

“neither UKHSA nor the Department for Health and Social Care have published an account of this programme to date, nor published any formal reports setting out the current state of the programme.”

The National Audit Office published its report, “Investigation into the UK Health Security Agency’s health security campus programme”, in February last year. That report sets out the key facts on and decision points in UKHSA’s programme, including its history, the causes of the delays and the issues so far at the Harlow site. I will not rehearse all those this evening, but reading the report may be instructive for the Minister.

I commend the right hon. Gentleman for securing the debate. I remember him bringing the matter before the House before; we have been in the House for the same amount of time, although he is much younger than me. Does he agree that replacing and modernising the UKHSA’s facilities through the programme is crucial to ensuring that the UK has the capabilities to identify, study and respond to the most dangerous pathogens in the world? Perhaps the way forward is to secure changes and to ask the Government to step in to assist the UKHSA to continue the crucial and excellent work that it already does.

I am grateful, as ever, to the hon. Gentleman for his support this evening, and he anticipates some of the points I will make later on.

I want also to refer to the Public Accounts Committee, which opened an inquiry into the UKHSA health security campus last year. The Committee heard evidence from the outgoing chief executive Professor Dame Jenny Harries and Shona Dunn, the second permanent secretary, but it was unable to publish a full report owing to the Dissolution of Parliament and instead published its conclusions and recommendations in a letter in May last year. There is a lack of clarity over where we are with these plans, and my simple purpose today is to secure the Government’s assessment of where we are now, 10 months into the new Administration.

Since that Adjournment debate in 2010, four general elections have been fought and I have had five years as a Parliamentary Private Secretary and seven as a Minister in four roles, but since 2015 I have never been offered any briefing on the future of the facility at Porton and on whether that initial decision, given the events of recent years and a sixfold increase in the costs—rather more than inflation—will be followed through on. As the constituency MP, I am eager to get to the bottom of the matter, and in seeking an update from the Minister this evening—and I certainly do not hold her individually responsible, given that she has only been in post for just over 14 weeks—I do want to seek an understanding about the financial obligations of the programme.

Will the right hon. Gentleman give way?

I am happy to give way to the Member representing Harlow.

I thank the right hon. Gentleman, who will know why I am here. Obviously I will sing the merits of relocation to Harlow, but I think we would both agree that we really want a decision on this and to know whether there will be a move or not, because the constituents both of us represent are currently in limbo.

I thank the hon. Gentleman who is very gracious in the way he puts over his point. It would be helpful for everyone in both our constituencies and for the country as a whole to know what is happening.

In addition to the HSA, the right hon. Gentleman’s constituency is home to the Defence Science and Technology Laboratory, and both do vital work on antimicrobial resistance. Does he know of any work that has been done by the Government to consider the implications for the UK’s AMR research of moving the two institutions apart?

I am extremely grateful for that very helpful intervention, because the hon. Gentleman points out the co-location of DSTL and the UKHSA at Porton, and that is a really important fact. The possibility of sharing category 4 facilities—something that has been resisted sometimes by one party or the other—is a material consideration when trying to mitigate excessive costs.

Last year’s NAO report set out that in February 2022, the programme had a staff team of 92 full-time equivalents based across multiple sites including Porton Down, London and other regional UKHSA centres, working across programme operations, management, delivery and capability, in addition to construction, finance and commercial and leadership teams. In November 2023, there were 69 FTE staff on the programme. The programme team is made up of civil servants and service providers, and has input from colleagues from other parts of the UKHSA.

It is very ironic to me that as I read over about 13 mentions of Porton Down that I have made in this Chamber over the last 15 years, so many of the Ministers who responded are now either retired, deposed or in the other place. I am concerned that the civil service people, for whom I have great respect having worked closely with lots of civil servants, have been blissfully unaccountable to any enduring authority or direction on this, while all of this work has been going on in the background. That just cannot be right.

As one of the ex-Ministers who is still here, perhaps I can contribute in a spirit of helpfulness to the current Minister. My right hon. Friend and I have discussed this issue many times. I was so concerned by this proposal as Secretary of State for Health and Social Care that I visited Porton Down and gave a very clear steer—not least when I found, to my huge surprise, that the nursery was being closed, which I thought was the wrong decision. He, like me, was Chief Secretary to the Treasury. As Chief Secretary to the Treasury, I gave a very clear steer that I was concerned that this move did not represent value for money, that times had changed and that the proposal was in error. I wonder whether the case study that is being presented to officials and the information that comes to Ministers properly reflects known concerns raised by Ministers, which appear to have been routinely ignored.

I am extremely grateful to my right hon. Friend; I recall the many conversations that we had on this matter.

How can we be in a situation where £530 million—Public Health England’s initial estimated cost for the whole programme in 2015—became an estimated £3.2 billion in 2023? I am not sure if that is the very latest figure. Of even greater concern to me is the fact that it was estimated in 2015 that the project would be completed by 2021, yet the best estimate now is that it will not be fully operational until 2036 at the earliest, which is 11 years away. That is if the programme remains at Harlow.

I had the great fortune to visit Porton Down with the Science, Innovation and Technology Committee and the Defence Committee. As a research scientist who has worked in category 3 suites, seeing category 4 suites at first hand was quite an eye-opener. I saw the incredible dedication of our scientists, who have served this country incredibly well despite the many attacks that have happened. We definitely need to renovate the labs and have a facility that is secure and that helps to support the jobs of scientists across the country.

I am extremely grateful to be made aware of the hon. Lady’s visit and of her support for the capabilities that we undoubtedly need in this country.

I will go back to give some context. As I mentioned in the 2010 debate, the Centre for Emergency Preparedness and Response, as it was known and as many—certainly my retired constituents—still refer to it locally, plays a crucial role in the life of this country and has done for more than 100 years. I suspect that one reason why it is a massive challenge to deliver this project is that a lot has happened during the considerable time that has elapsed since 2015, much of it unexpected. As the hon. Member for Strangford (Jim Shannon) mentioned, Porton’s sister establishment, DSTL, was instrumental in dealing with the Novichok attack in 2018 in Salisbury. During covid, the established expertise at Porton was critical in the support of our nation during the vaccine development and testing process.

My hypothesis is that while peacetime, desk-based studies in Whitehall may have favoured Harlow as a hub back in 2015—it may also have been a function of the former Chancellor George Osborne’s PPS being the MP for Harlow—the reality of how the actual needs of the country played out in practice has shown beyond doubt that Porton has remained instrumental in delivering translational health research for our nation in the interim. Instead of that group of civil servants challenging themselves in the light of events, it was more convenient, in an environment where political sponsorship had moved on, for them to keep driving forward the Harlow vision, even when the labs needed conversion, the planning process was delayed and the lifespan of Porton proved to underline the resilience of the Wiltshire site.

That was reinforced to me just three years ago in 2022, when the Health and Social Care Secretary, Sir Sajid Javid, came to visit Porton Down alongside Professor Dame Jenny Harries, the chief executive, to open a new groundbreaking facility. The two-storey, 22,000 square foot building was one of two that made up a new £65 million vaccine development and evaluation centre, which was built to help to develop and licence new vaccines and cement the UK as a global leader in testing against future variants of the virus. At the time, the Department’s press release said:

I thank the right hon. Member for Salisbury (John Glen) for securing this important debate and for his passionate advocacy on behalf of his constituents for the vital work conducted by the UK Health Security Agency at its Porton Down site. I also take the opportunity to recognise the intervention from my hon. Friend the Member for Harlow (Chris Vince) and his passionate advocacy on behalf of his constituents.

Before I come to the decision-making process, I want to use this opportunity to reference some of the incredible work that takes place on the site. Whether it is advancing vaccine development to address global health threats, such as Mpox, or leading the world in evaluating vaccines to ensure that we have effective programmes that save countless lives, Porton Down stands as a pillar of excellence in our national health security infrastructure.

Through the UKHSA science strategy, we are committed to securing health and prosperity with partners in industry and academia. That is why we established the vaccine development and evaluation centre on the Porton Down site, securing learning from the pandemic and advancing our critical research on vaccines. Porton Down’s diagnostics capabilities are equally vital, providing the UK’s only 24/7 service for detecting rare and imported pathogens, including life-threatening diseases such as Marburg virus, Ebola and Lassa fever. The site also plays a unique role in environmental microbiology and biosafety, helping us to understand better how infections spread in real-world settings.

Porton Down’s role does not stop at healthcare. It reaches into our ecosystems, our food chain and our environment. Porton Down is a national leader in medical entomology, including the surveillance of invasive mosquitoes and ticks. Its work ensures that the UK can rapidly detect and respond to vector-borne diseases, protecting the public from threats before they gain a foothold. The site’s food, water and environmental microbiology teams provide additional expertise that is critical to national resilience and the Government’s work on climate change; but, crucially, the work of those globally leading teams requires the best facilities.

I could talk about the benefits of the Harlow site for a long time, and I often do, but on this occasion I will be brief. May I ask the Minister, when the Government are making those decisions, to take account of the fact that the Harlow site is very much shovel-ready and is ideally located, given its strong infrastructure and travel links and its proximity to existing health clusters? The site would very much future-proof this important work.

I can assure my hon. Friend that the benefits of all options will be considered.

Will my hon. Friend also take into account the multidisciplinary roles and spaces involved in the jobs that she has outlined, and the fact that the existence of a hub, with most of those elements together in one place, will stimulate innovation and great healthcare outcomes?

I can assure my hon. Friend, and the House, that all considerations will be taken into account when this decision is made. As I have said, the Government are thoroughly assessing options, including all those that have been raised. Two main options are under consideration: to rebuild and refurbish some facilities at Porton Down and its sister site at Colindale in north London, or to build an entirely new facility in Harlow, Essex. In either event, the staff working in the defence, science and technology laboratory at Porton Down will remain there, and even when a decision is made on those options, nothing will happen overnight. Complexity and rigorous scientific requirements mean that completion will take more than a decade, which is why we continue to invest in maintaining our current site and facilities at Porton Down, with £38.1 million allocated for capital investment in the recent spending review.

The Government are committed to ensuring that we retain the ability to carry out the vital functions of UKHSA Porton Down. Members, the National Audit Office and the Public Accounts Committee have all advocated for an urgent decision, but identifying the right site that delivers on this mission, while ensuring best value for money, is a complex decision and one that we must get right. I can assure the House that extensive discussions are taking place between UKHSA, the Department of Health and Social Care and His Majesty’s Treasury to inform a decision, and I can confirm that this decision will be taken as part of the spending review, which will conclude next month.

Having had the opportunity to be involved in spending reviews, I would be interested to know the current provision for this scheme in the budget over the next three years, because alongside assessing the benefits, there will be the simple question of what is affordable. The NAO has set out an estimate of over £3 billion for the overall cost, but what has the Department provisioned for the spending review period?

I do not currently have the detail on that, but I will write to the right hon. Gentleman following this debate. I can confirm that he knows as much as I do about what might be in the spending review, because those decisions have yet to be made, but more information will be made available as soon as possible.

As the Secretary of State said earlier this year,

“The worst decision is indecision”,—[Official Report, 13 March 2025; Vol. 763, c. 1295.]

and this Government are committed to sorting out this issue once and for all. A decision will be made in a matter of weeks. In anticipation of that decision, UKHSA is taking steps to prepare to remobilise the programme at pace. It recently invited the Government Internal Audit Agency to conduct a short review of its remobilisation plans as part of its commitment to ensure that there is maximum transparency and rigorous assessment of the programme. The agency has also obtained advice from the National Infrastructure and Service Transformation Authority.

I am sure that colleagues from across the House share my view that the work conducted at Porton Down is critical to protect the country. The recent pandemic put into sharp focus how this work is fundamental to keeping us all safe. Although there is still the outstanding question of how we can best preserve the facilities for the country, whatever decision we take will be made in full consultation with the staff at Porton Down, whose critical skills are highly valued by us all.

I thank the right hon. Member for Salisbury again for raising this vital issue, and all Members who have intervened in the debate. I commit to updating him on progress once a decision is made.
