A homeowner who has successfully demonstrated that his heat pump installation was not carried out with reasonable care and skill should not have to embark on an entirely separate battle to establish whether the financial protection surrounding that installation will actually help him. Yet that is precisely what happened in a case recently examined by Renewable Heating Hub, where two inspections identified work that did not comply with Building Regulations, an independent adjudicator directed the installer to pay £11,525 and the original contracting company ceased trading, leaving the homeowner facing a further dispute over the workmanship warranty intended to provide protection in circumstances such as these. The story has finally reached a welcome financial conclusion, with £9,750 paid towards the necessary remedial works, but the sequence of events raises questions about how certification, complaints procedures and consumer protection operate when a heating installation goes wrong.
What makes this case particularly revealing is that the homeowner did not simply complain about an expensive heating system that failed to meet his expectations. He followed the formal processes available to him, supplied substantial documentary evidence, cooperated with inspections and ultimately secured an independent decision in his favour.
Along the way, however, the company responsible for his installation entered liquidation, a separate business became involved, the original Building Regulations compliance certificate was withdrawn and the homeowner found himself trying to establish which organisation, if any, would finance the work required to put his property right. For all the reassurance offered by certification schemes, workmanship guarantees and consumer codes, his experience illustrates how difficult it can become to turn an established entitlement into a practical remedy once the original relationship between homeowner and installer has collapsed.
Renewable Heating Hub has examined the independent adjudicator’s final decision, the findings of two OFTEC inspections, the relevant Building Control observations and extensive correspondence between the parties. We have also received a statement from OFTEC following a detailed request for comment. The homeowner has asked to remain anonymous, and we are respecting that request. Our purpose is not to suggest that every allegation made during this dispute has been substantiated, or that the eventual payment establishes legal wrongdoing by OFTEC. It is to examine what happened, why the process became so prolonged and what the experience reveals about the protections on which homeowners are encouraged to rely.
The installation in question was completed in April 2024 by L H Cook Plumbing & Heating Ltd, a business the homeowner had used for boiler servicing for a number of years. The project involved replacing an oil fired heating system with an air source heat pump and associated equipment, alongside underfloor heating and domestic plumbing work. A separate company had undertaken the heating system design, while L H Cook’s contractual responsibilities were expanded during the project. The installation received support through the £7,500 Boiler Upgrade Scheme and was issued with an OFTEC Building Regulations compliance certificate, providing the documentation that an ordinary homeowner would reasonably associate with a professionally completed and certified installation.
Problems subsequently emerged with the operation of the heating, initially involving suspected air and circulation issues. Those concerns led to a complaint and an OFTEC inspection in May 2025. Although OFTEC did not substantiate the original circulation problem during that visit, its inspection identified other deficiencies, including inadequate insulation on heating pipework, outstanding documentation and notification requirements relating to the unvented cylinder and a safety discharge pipe arrangement that did not comply with the relevant Building Regulations guidance. A further inspection in September identified additional areas of pipework requiring insulation, including concealed sections within the property. The findings were not simply matters of appearance or an argument about whether the installer had made the pipework look sufficiently tidy. They concerned compliance with the standards governing the work that had been undertaken.
Correcting those deficiencies was also considerably more complicated than slipping additional insulation around a few accessible pipes. The local authority Building Control observations recorded gaps in existing insulation and pipework installed too closely together to accommodate the replacement insulation in certain locations, meaning that some pipes would need to be adjusted before the necessary work could be completed. Elsewhere, access would be required through walls, floors and concealed spaces, followed by the inevitable making good. A quotation for the remedial work came to £9,750, reflecting not only the insulation itself but the disruption associated with reaching and correcting work that had already been incorporated into the finished property. Building Control indicated that a completion certificate could be withheld until the contravening work was rectified.
L H Cook disputed significant aspects of the homeowner’s complaint. In its submissions during the subsequent adjudication, the company argued that it had neither designed nor installed every part of the heating and plumbing systems, maintained that certain responsibilities rested with other contractors and said that it had made repeated attempts to resolve the outstanding issues. It also alleged that the homeowner had interfered with remedial work and raised concerns about the safety of electrical installations at the property. Those arguments deserve to be acknowledged because the dispute was not simply a case of an installer admitting every defect and refusing to do anything about it. However, the adjudicator ultimately found that the company had not adequately substantiated its broader allegations about the homeowner’s conduct and that the relevant failures in workmanship fell within its contractual responsibilities.
The adjudication itself is an important part of this story because it was not an unquestioning endorsement of everything the homeowner alleged. On one disputed technical point concerning the use of radiused insulation bends, the adjudicator favoured the installer’s position, while a separate claim for additional energy costs was rejected because the supporting evidence was insufficient. The decision also recorded no breach of MCS standards, explaining that no specific allegations of such breaches had been presented for determination. Nevertheless, the adjudicator accepted the findings concerning inadequate pipework insulation, insufficient spacing for compliant insulation and the incorrectly installed discharge arrangement, concluding that L H Cook had failed to perform the relevant services with reasonable care and skill under the Consumer Rights Act 2015.
By July 2026, the homeowner had a detailed independent decision directing the installer to refund £9,750 towards the remedial work, reimburse £655 for Building Control certification, pay £1,000 for distress and inconvenience and refund the £120 adjudication fee. The total was £11,525. The adjudicator also recognised that the relationship between the parties had broken down irretrievably and considered it inappropriate to direct the original contractor to return to complete the work, preferring a financial remedy that would allow the homeowner to engage somebody else. L H Cook rejected the decision, with its response recorded in the adjudication stating that no payments would be made. Renewable Heating Hub subsequently approached L H Cook and David Collins for comment on the case but received no response.
It would be tempting to regard that as the end of the investigation, another example of poor workmanship followed by an installer refusing to accept an independent decision. Unfortunately, the circumstances surrounding the business itself made the situation considerably more complicated. The original contracting company, L H Cook Plumbing & Heating Ltd, had entered creditors’ voluntary liquidation in February 2025 and was eventually dissolved in August 2026. A separate company, L H Cook Plumbing, Heating & Renewables Ltd, had been incorporated in January 2025, with David Collins associated with both businesses. Although the names were similar and the individuals involved overlapped, these were distinct legal entities, a distinction that became central to the homeowner’s attempts to establish who remained responsible for putting the installation right.
OFTEC subsequently confirmed that it had received paperwork on 3 February 2025 requesting a change of name for the certified installer business, together with an undertaking that the new company would assume responsibility for previous work undertaken by the original company. OFTEC says this included the installation in question and explains why the associated compliance record was changed. The precise legal and contractual implications of that arrangement have not been independently determined, and an undertaking given to a certification body should not automatically be treated as proof that every contractual obligation was validly transferred to another company. Nevertheless, the circumstances raise an obvious consumer question. If the original installer had entered liquidation and a separate business was being treated as responsible for its previous installations, when and how should the affected homeowners have been informed, and what enforceable rights did the arrangement actually provide them?
The homeowner maintains that he was not informed of the original company’s insolvency when his complaint was progressing, and that he had never agreed to transfer his contractual relationship to the new entity. OFTEC’s correspondence, meanwhile, maintained that the installer remained able and willing to undertake remedial works, even though earlier exchanges showed how difficult that relationship had become. In December 2025, OFTEC’s own compliance services manager acknowledged correspondence indicating that L H Cook would not be undertaking further remedial work and advised that the case appeared unlikely to reach a satisfactory conclusion. The homeowner had refused David Collins personal access to the property, citing concerns about his conduct during the dispute, but maintained that he had offered access to other technicians, who had attended on an earlier occasion. Collins denied behaving aggressively or confrontationally. This is important because refusing entry to one individual following a serious breakdown in trust is not necessarily the same as refusing to allow any competent professional to correct the work.
OFTEC’s position was that the continuing breakdown in the relationship had frustrated attempts to obtain a resolution, and in January 2026 it withdrew the Building Regulations compliance certificate because the installation had not been brought into compliance. It advised that the work would need to be regularised through the local authority. From a technical and regulatory perspective, there is an understandable reason not to leave an installation certified as compliant when deficiencies remain outstanding. The difficulty is what happens when the homeowner subsequently attempts to obtain protection through a warranty associated with that original certification. If defective workmanship has been identified, the original installer has ceased trading and the certificate is then withdrawn because those defects remain uncorrected, can the act of withdrawing the certificate affect the very financial protection intended to address the problem?
That question became the centre of the subsequent dispute. OFTEC’s workmanship warranty provides limited cover for qualifying defective work over a six-year period, including circumstances in which the original registered installer has ceased trading or entered insolvency. It is not an unrestricted insurance policy, nor does it automatically guarantee payment of everything awarded by an adjudicator. Its terms contain defined conditions, exclusions and a financial limit. The homeowner’s argument, however, was that the original company’s liquidation and the discovery of non-compliant work had occurred before the certificate was withdrawn, and that those circumstances should have allowed him to make a claim. OFTEC’s earlier correspondence placed emphasis on the availability of remedial work through Collins and the successor business, while the homeowner maintained that this did not resolve his entitlement under the warranty attached to the original installer.
By October, matters had escalated further. The homeowner had appealed OFTEC’s previous handling of the case to its board and submitted a Letter Before Claim against OFTEC Ltd and OFTEC Warranty Ltd seeking £9,750 towards the cost of remedial work. This was a separate proposed claim concerning the workmanship warranty, rather than an attempt to enforce the entire £11,525 adjudication award against OFTEC. The appeal also questioned the administrative handling of the compliance certificate, the treatment of the successor company and the independence of the appeal arrangements where directors held roles across the organisations involved. These were questions about governance and procedure, not established findings of improper conduct or personal financial benefit.
Then, on 22 October 2026, the position changed.
In a letter issued on behalf of OFTEC chairman Neil Sawers, the organisation concluded that the homeowner was eligible to claim under the OFTEC Workmanship Warranty because the original installer business had ceased trading. The chairman decided that it was unnecessary to convene the requested appeal committee in light of that conclusion and offered to authorise payment of £9,750 in full and final settlement. Importantly, he did not accept that OFTEC’s earlier handling had been improper, describing the previous options offered to the homeowner as reasonable and permitted within the registration scheme rules, while recognising the homeowner’s right not to allow Collins and the new company access to his property.
The homeowner accepted the offer and has since confirmed to Renewable Heating Hub that the £9,750 has been paid. Interestingly, he reports that the payment came from OFTEC Ltd rather than OFTEC Warranty Ltd, the company named in the workmanship warranty documentation. That does not establish anything improper about the payment arrangements, which could reflect an internal funding or settlement decision, but it reinforces the need for clarity about which organisation administers the protection, which organisation bears the financial obligation and how the distinction is explained to consumers.
Following our request for comment, OFTEC provided the following statement:
“We understand how frustrating this has been for the homeowner and we’re sorry for the difficulties they have experienced with their heat pump installation. We set high standards and work with the aim of ensuring all customers receive positive outcomes when a heating system is installed by an OFTEC registered business. As soon as we were made aware of the installation in question, OFTEC proactively engaged with the homeowner, installer and other relevant parties, to seek a resolution to the situation. We are pleased to say that the case has now been satisfactorily resolved, and we will continue to review our systems to further enhance the support we have in place.”
It is right to acknowledge that OFTEC did engage with the complaint, conducted inspections, identified deficiencies and ultimately provided a financial resolution that the homeowner has accepted. The chairman’s intervention delivered an outcome that had previously appeared increasingly difficult to obtain, and the willingness to reconsider the warranty position is significant. Equally, the statement does not address all the detailed questions we put to OFTEC about the original and successor companies, the withdrawal of the compliance certificate and the route by which warranty eligibility was ultimately recognised. Those questions remain relevant, particularly because the final decision relied on the original installer having ceased trading, a circumstance that had existed long before the October settlement.
There is a further distinction that probably needs to be made between the financial conclusion and the physical condition of the installation. The homeowner now has the £9,750 intended to fund the remedial work, which is a substantial and welcome outcome, but payment itself does not insulate the pipes, correct the discharge arrangement or regularise the outstanding Building Regulations position. Those steps still have to be completed and appropriately certified. Nor should the £9,750 settlement be confused with payment of the full £11,525 directed against the original installer. The adjudication and the subsequent warranty dispute were separate processes with different parties and different remedies, and the documentation available to us does not establish that every element of the earlier award has been recovered.
OFTEC’s chairman has also made commitments extending beyond this individual settlement. His October letter states that he has requested a review of the registration scheme’s entry requirements, particularly in relation to businesses that are wound up and subsequently replaced by new companies, and has instructed increased surveillance of L H Cook Plumbing, Heating & Renewables Ltd. He also states that registration will be removed if the compliance evaluation process warrants that action. Those commitments deserve recognition, although heightened surveillance is not itself proof of further wrongdoing and no conclusion should be drawn about the quality of other installations without independent evidence. The relevant test will be whether the promised scrutiny is undertaken effectively and whether its findings lead to appropriate action when necessary.
This is where the case moves beyond the circumstances of one heat pump installation. Certification systems inevitably operate within defined rules, accreditation requirements and limits on their powers, while consumer codes, adjudicators and warranty providers perform different functions. An inspection can establish non-compliance without determining contractual damages. An adjudicator can determine a remedy without having the resources to carry out the work. A warranty administrator can assess eligibility without having been responsible for the original installation. Each distinction may be legally or administratively necessary, but the homeowner experiences the resulting system as a single purchasing decision followed, when things go wrong, by several organisations explaining which parts of the problem fall outside their responsibility.
That fragmentation becomes particularly damaging when a company ceases trading. For the homeowner, it is largely irrelevant whether the installer has dissolved, reorganised, adopted a similar trading name or transferred its registration arrangements to another corporate entity. The practical requirement remains the same. The work was paid for, it was certified and it should comply with the relevant standards. If it does not, the consumer needs a clear route to correcting it without being forced to become an expert in insolvency, company law, alternative dispute resolution and the contractual boundaries between related warranty organisations. Those distinctions may be unavoidable behind the scenes, but they should not become obstacles that an ordinary household has to resolve before obtaining meaningful protection.
The question is not whether OFTEC eventually did the right thing by recognising the claim and authorising payment. It did provide the settlement, and that outcome should be reported fairly. The question is why the homeowner had to pursue such a prolonged process, culminating in a formal appeal and threatened court proceedings, before reaching that point. OFTEC maintains that its earlier actions were reasonable and that it had sought a resolution throughout. The homeowner maintains that those actions delayed access to the protection he believed was available. Neither account needs to be embellished to recognise that the dispute consumed an extraordinary amount of time and effort before the money required for remedial work finally became available.
There is a tendency within consumer-protection systems to measure success through procedures completed, correspondence answered, inspections undertaken and cases closed. Those activities are necessary, but they are not the outcome a homeowner purchased. A completed complaint file does not make an installation compliant, and an adjudication award against a company that cannot or will not pay is of limited practical value unless another mechanism allows the customer to obtain the remedy. The strongest measure of consumer protection is therefore not simply whether the correct procedures were followed, but whether those procedures produce timely, proportionate and enforceable outcomes for the people they are intended to protect.
This homeowner ultimately secured the funds for the remedial work, and his persistence deserves recognition. But it should not take exceptional persistence to achieve an ordinary entitlement. Most people installing a heat pump are not interested in becoming specialists in certification rules or spending evenings analysing warranty clauses and insolvency records. They are making a substantial investment in their home and reasonably expect the organisations whose credentials helped them choose an installer to provide meaningful assistance if the work subsequently proves defective.
The £9,750 payment is a welcome conclusion to a difficult financial dispute, and it demonstrates that the protection system can ultimately deliver a tangible result. The deeper test is whether the experience leads to improvements that allow the next homeowner to reach an appropriate resolution without anything approaching the same ordeal.
Consumer protection should not depend on a homeowner’s ability to outlast the complaints process. It should be designed so that they never have to.
