When the Company Behind a £154m Contract Changes: Five Questions Procurement Should Ask
By Alexander Jaiyesimi MSc MCIPS · Founder, SupplierSense · 9 min read
Most supplier assessments are built around a name. The tender response carries it, the evaluation scores it and the contract register records it. But obligations are not held by names. They are held by legal entities, each with its own company number, balance sheet, liabilities and relationships.
That distinction usually sits quietly in the background. It becomes very visible when the entity carrying a major contract changes, and then something goes wrong.
The London Borough of Hackney's Britannia Phase 2b scheme is a useful public example. It is not a story about a bad procurement decision. It is a story about how the risk a buyer holds can move while the supplier's name barely changes, and about what procurement should reassess when it does.
Procurement takeaway. A change in contracting entity is a material supplier event. It should trigger a reassessment of the risk the organisation actually holds, not just an update to the supplier record.

SupplierSense Intelligence Briefing 004 - A £154m Contract Changed Companies. Then Both Entered Administration. (4:31). Watch on YouTube.
Two companies sit at the centre of this case. Their names were almost identical. The companies weren't.
Ardmore Construction Limited (company number 01185592) entered administration on 28 August 2025, according to Companies House. Ardmore Construction Group Ltd (company number 11890551) entered administration on 11 June 2026, according to Companies House.
These are separate legal companies with separate company numbers. The Local Democracy Reporting Service described the first as "a separate collapse from that of its parent."
According to reporting by the Local Democracy Reporting Service, published in the Hackney Citizen, Hackney Council handed the £153.9m Britannia Phase 2b contract to Ardmore Construction Limited in 2023. The same reporting says Ardmore then asked for the contracting party to be changed to its parent, Ardmore Construction Group Ltd, for reasons around "succession planning". Senior officers reportedly approved the change under delegated powers, after legal advice that the new company was capable of fulfilling the contract and that the change did not alter the substance of the agreement. The reporting adds that the council declined a Freedom of Information request for some of the related material, citing legal and commercial sensitivity.
Hackney's own July 2026 Cabinet report records that the council entered into the design and build contract with Ardmore Construction Group Ltd on 21 July 2023. We have not located a published council decision that sets out the change of contracting party itself, so that sequence is presented here as reported.
What followed is set out in Hackney's own published information. Construction paused after Ardmore Construction Group entered administration. The council terminated its contract with Ardmore Construction Group Ltd on 2 July 2026. Wates took over management of the site, and by 27 August the council had entered a Pre-Construction Services Agreement with Wates. The council said it expected to take around three months to assess the existing works, engage with the supply chain and agree new contracts before recommending how construction could restart.
Hackney's July 2026 Cabinet decision records that the cost of delivering Phase 2b is now likely to exceed the approved budget of £196.875m before costs can be recovered. The report gives the reason as the additional time needed to procure, mobilise, assess and recommence works on site with a replacement contractor. It now assumes handover of the new homes in late summer 2027, against an earlier forecast of November 2026.
The council also had protection in place. Its report states that a 10% performance bond was procured as part of the contract and that a parent company guarantee was secured from Ardmore Group. It also notes that losses need to be incurred and demonstrated before they can be agreed and recovered from the bond provider.
This article does not suggest that the change of contracting entity caused either administration. The case is useful for a different reason: it shows clearly what a buyer is exposed to when the entity behind a contract changes, and what that exposure looks like when it crystallises.
Entity changes happen for many ordinary reasons: group restructuring, succession planning, novation after an acquisition, or moving contracts into a dedicated trading company. Most are benign. That is exactly why they tend to be handled as administrative changes rather than risk events.
1. Who now carries the obligation?
Start with legal identity, not branding. Confirm the registered name, company number and registered office of the new contracting party, who owns and controls it, and whether it holds the licences, accreditations, insurances and approvals the contract assumes.
Similar trading names and shared group branding do not establish legal identity. "Ardmore" described both companies in this case. Only the company number told them apart. A supplier master record keyed on name, or a contract register that records a trading name, can make two different risk profiles look like one.
2. Has financial and operational capacity changed?
Due diligence on Entity A does not transfer to Entity B. The new party may have a different balance sheet, different debt, a different trading history, and a different relationship with the people, plant and subcontractors that will actually deliver the work.
A useful test: if we were awarding this contract to the new entity today, would it pass the same assessment?
If the answer is "we don't know", the change has not yet been assessed. It has only been approved. This is not a judgement on whether a particular change should go ahead. A parent company may well be the stronger counterparty. The point is that the conclusion should be reached on the new entity's own evidence.
3. Do contractual protections still operate as intended?
Parent company guarantees, performance bonds, insurance, warranties, indemnities, collateral warranties and liability caps are all written with particular parties in mind. When the contracting entity changes, each needs checking. Does the guarantee still sit above the right company? Does the bond still respond to this party's default? Who is the guarantor now, and what is its financial position?
The Britannia case also shows a more important distinction: financial protection is not the same as operational continuity. Hackney had a performance bond. Its own report explains that losses must be incurred and demonstrated before they can be recovered. A bond can help with the cost of failure. It does not keep a site running, retain a supply chain or prevent the months needed to assess, re-procure and remobilise.
Where a guarantee comes from within the same group as the contractor, its value depends on the financial position of that group. That makes it a question for group-level intelligence, not just contract drafting.
4. What exposure exists across the wider corporate group?
Separate legal entities are not necessarily separate risks. Group companies can share ownership, directors, financing, systems, staff, premises, customers and reputation. In some circumstances, liabilities can also extend across associated companies.
Hackney Citizen and Construction Enquirer both reported that, before the group's administration, the High Court had made a Building Liability Order in respect of historic cladding claims. Hackney Citizen reported that the order made multiple companies within the wider Ardmore group liable. We make no assessment of the reasons for either administration. The procurement point is more general: under the Building Safety Act 2022, liabilities connected to one company can be extended to associated companies, so a contractor's exposure can depend on events elsewhere in its group.
Procurement therefore needs two views at once. Entity-level intelligence tells you about the company you have contracted with. Group and network intelligence tells you what that company is connected to, and what could reach it.
5. How replaceable is the supplier today?
This is the question most likely to be underestimated. At contract award, a main contractor on a large scheme can look highly substitutable. There is an open market, several credible bidders and a clean scope. Once delivery starts, that changes. The incumbent holds partly completed work, design decisions, site knowledge, subcontract relationships, warranties and interfaces with other packages. A replacement has to inherit all of that, including defects it did not create and cannot yet see.
Hackney's July 2026 report is unusually clear on this. During contingency planning, the council's technical team canvassed 14 contractors to test the market's likely response to an insolvency scenario. The report states that contractors would not compete through a mini-competition for the work, though they were interested in working with the council on a directly appointed basis. The same report identifies the time taken to recommence works as the main driver of cost escalation. It adds that the longer a site is left, the greater the risk of materials, equipment and infrastructure becoming damaged, out of warranty or in need of replacement.
A supplier that appears replaceable at contract award may be considerably harder to replace during delivery.
The lesson travels well beyond construction. Substitutability should be reassessed at key delivery milestones and whenever the supplier's circumstances change, not assumed from the original tender. Useful prompts include:
· What would a replacement need to inherit, and how long would it take to assess?
· Which subcontractors, designs or warranties are tied to the current supplier?
· Is there a realistic route to market mid-delivery, or only a direct appointment?
· What does each month of pause cost, before any recovery?
Procurement takeaway. Replacement risk grows as delivery progresses. The question is not only "could we replace this supplier?" but "how long would it take, what would we inherit, and what would we pay while we wait?"
Most supplier due diligence clusters around a few checkpoints: pre-qualification, tender evaluation, contract award, annual review and renewal. Those checkpoints matter. The difficulty is what happens between them.
In that gap, a legal entity can change. Ownership, directors and group structure can change. Financial capacity can weaken, guarantees and insurance can lapse or move, liabilities can arise elsewhere in the group, and adverse media can appear. At the same time, the buyer's dependency on the supplier usually increases and the supplier's substitutability usually falls.
None of this is visible if the only question being asked is: was this supplier acceptable when we appointed them?
The more useful question is: what has changed in the risk we hold today?
In practice, that means treating certain events as triggers for reassessment rather than as administration:
· a change of contracting party, novation or assignment
· a change of ownership, control or group structure
· administration, a moratorium or insolvency activity anywhere in the supplier's group
· a change of guarantor, bond provider or insurer
· material litigation or liability orders affecting the supplier or its associated companies
· a significant change in the buyer's dependency on the supplier
Each trigger should prompt a proportionate review by the people best placed to judge it, with procurement, legal, finance and the contract manager looking at the same updated picture.
· Supplier risk doesn't sit in a trading name. It sits in legal entities, obligations and dependencies.
· A change of contracting entity is a material supplier event and should trigger reassessment.
· Due diligence on one entity does not carry over to another, even within the same group.
· Financial protection such as a performance bond does not guarantee operational continuity.
· Group-level connections can bring risk to a contractor from elsewhere in its group.
· Substitutability at award is not the same as substitutability mid-delivery.
When a critical supplier changes legal entity, the supplier record shouldn't be the only thing that changes. The risk assessment should change with it.
SupplierSense helps procurement teams understand supplier risk and changes in exposure using publicly available intelligence, including company and group structure, financial signals, sanctions, adverse media and corporate events. It is designed for continuous supplier intelligence rather than relying only on point-in-time assessments, and it complements legal, financial and commercial due diligence rather than replacing it.
