For many flat owners, the decision to refinance their property is a strategic financial move. Whether you’re looking to secure a better interest rate, release equity, or consolidate debt, remortgaging can be a savvy way to improve your financial position. But when your building is undergoing major works — such as cladding replacement, structural repairs, or fire safety improvements — the process becomes significantly more complex. Navigating the remortgaging process during such a disruptive and uncertain time requires foresight, patience, and a thorough understanding of how lenders perceive risk.

Why Lenders View Major Works with Caution

When you apply to remortgage, lenders assess a range of criteria to determine whether your property qualifies for a new mortgage deal. These include the borrower’s creditworthiness, income, and expenditure, but crucially also the property itself. If your flat is situated in a building where substantial work is ongoing or planned, red flags may be raised.

Lenders are wary because major works can impact the value of a property, either temporarily or permanently. The uncertainty surrounding projected costs, timelines, and potential hidden issues can deter them. Moreover, if the works relate to external safety issues such as cladding remediation, particularly since the Grenfell Tower tragedy, some lenders may either decline to lend outright or only provide offers contingent on certain conditions.

It’s important to remember that lenders are not only concerned about today’s value of a property, but also its future resale potential. If a property appears difficult to resell or could face further repair requirements in the short term, lenders may see it as a bad investment. Some may impose stricter lending criteria, reduce the loan-to-value ratio (LTV) they’re willing to offer, or increase their interest rates to compensate for perceived risk.

Typical Major Works That Cause Concern

Not all forms of building work will trouble mortgage lenders equally. Cosmetic or routine maintenance — like landscaping, repainting communal areas, or lift refurbishments — rarely pose an issue. However, more intrusive or expensive undertakings raise alarm bells.

Cladding remediation remains a heightened concern for many lenders due to the widespread regulatory changes and the publicity the issue has received. Buildings requiring External Wall System (EWS1) forms, for example, may still struggle to obtain quick approvals, particularly if the relevant documentation is missing or incomplete.

Other problematic works include structural reinforcements, concrete repairs, roof replacements, and fire safety retrofitting. Anything that suggests the building might be unsafe or that the leaseholder might bear a significant unexpected financial burden gives lenders pause.

The Importance of Transparency and Documentation

While the existence of building works can’t be swept under the rug, transparency and preparation can go a long way in mitigating lender concerns. When applying to remortgage, it is essential to provide comprehensive documentation on the nature of the works. This might include architect’s reports, structural surveys, details of the scope of works, timelines, and any communications from your managing agent or freeholder.

The more clarity you can provide about what the building works entail, how they are being funded, and when they’re expected to be completed, the better positioned you will be in discussions with both mortgage advisers and lenders.

If remedial works are being funded by government schemes such as the Building Safety Fund, this should be clearly indicated. Government support can help alleviate lender concerns, particularly where leaseholders are not being personally asked to pay for expensive cladding replacement or safety upgrades.

It is also helpful to demonstrate that the building’s management structure is robust and proactive. Professional managing agents, visible progress, and evidence of compliance with updated building regulations can bolster lender confidence in the building’s future resilience and management.

Valuation Hurdles

During a remortgage application, one critical stage is the lender’s property valuation. This is where the impact of major works often becomes acutely tangible. Surveyors are likely to look closely at both current and planned construction or remediation activities in the building. In many instances, they may apply a down-valuation if they believe the works compromise the current market value of your flat.

A down-valuation can seriously impact the mortgage deal you can obtain, particularly if your original offer was based on a higher property valuation. This might force you to accept a higher rate or contribute more equity upfront to secure the loan. For those with modest equity, this can derail remortgage plans altogether.

To navigate this, be prepared to support the valuation process with as much verifiable information as possible. Include recent sales data from similar flats, especially if they are located within the same building or nearby properties unaffected by the same issues. Although surveyors must remain impartial, they sometimes welcome additional context when forming their professional opinion.

Leaseholder Liabilities and Service Charges

Another aspect that lenders investigate is the financial liability leaseholders may incur as a result of the work. If you’re likely to be slapped with a hefty service charge bill or section 20 notice requiring contributions to a multimillion-pound repair scheme, lenders may view you as financially overexposed.

In such cases, the mortgage underwriter may require confirmation that sufficient funding is in place and that costs are capped or covered by third parties such as insurance or government grants. This is particularly relevant in leasehold blocks where the exact dimensions of leaseholder contributions can be uncertain or in dispute.

If your service charge account is in arrears, this can be especially detrimental. It’s advisable to bring your payments up to date before entering the remortgaging market. Keeping clean records and maintaining communication with the managing agent regarding any anticipated service charge increases demonstrates responsibility and foresight — qualities that lenders appreciate.

The Role of Mortgage Brokers

Given the complexity involved in securing a mortgage under these circumstances, professional mortgage advisers can prove invaluable. A broker with experience handling cases in blocks undergoing major works will often know which lenders are more open-minded, flexible, or have previously issued mortgage offers on comparable properties.

Mortgage advisers can also assist in packaging your application to maximise its appeal. They understand what information underwriters seek and can assist in pulling together all documents and responses in a cohesive and compelling manner. In many cases, they may advise on timing — suggesting strategic delays to coincide with certain project milestones or improved lender sentiment.

Some brokers also have access to specialist lenders, such as building societies or niche mortgage providers, who may be better equipped or more willing to consider flats in buildings under construction or remediation. While specialist lenders may charge slightly higher interest rates, they can be crucial when mainstream lenders decline an application.

Timing Is Everything

Unfortunately, attempting to remortgage just as scaffolding goes up is rarely opportune. Timing your application carefully can be the difference between success and frustration. Many experienced landlords and property owners wait until works are completed or reach a stage where their outcomes are predictable before approaching lenders.

If you’re stuck on a high standard variable rate (SVR) and cannot wait months for completion, all is not lost. In some scenarios, you may be able to take a short-term fixed rate with your current lender without needing a new valuation. Known as a product switch or rate switch, this can provide breathing space and limit financial exposure without the rigmarole of affordability checks or valuation concerns.

Alternatively, some lenders are willing to issue mortgage offers on a case-by-case basis even where works are pending, provided they are satisfied the flat maintains ‘mortgageable condition’ and that clear information is available. In these scenarios, leaning on your broker and ensuring total transparency is especially important.

Legal and Conveyancing Considerations

It’s not only lenders who scrutinise properties with ongoing works. Your solicitor or conveyancer also plays a pivotal role in the remortgaging process. They are responsible for investigating the legal standing of the lease, the scope of the building works, finance arrangements, and historic disputes.

Delays in obtaining paperwork, such as EWS1 forms, annual accounts, or detailed breakdowns of major works, can prolong or compromise your remortgage application. Some solicitors may also raise concerns based on prior tribunal decisions affecting the building or its freeholder.

To avoid unwelcome surprises, engage your solicitor early and share all documents related to the works upfront. This allows them to flag any red flags and liaise effectively with the lender’s legal representatives. Remember, most mortgage offers are time-sensitive — valid for three to six months — and legal holdups can risk expiry and necessitate resubmission.

Making the Decision: Is It Worth Remortgaging Now?

One of the biggest strategic decisions homeowners will need to make is whether to proceed with remortgaging during major works or wait until conditions improve. This ultimately depends on your individual financial goals and the severity of the building’s condition.

If you have a significant mortgage, even small reductions in interest rates can yield meaningful monthly savings. However, if attempting a remortgage now risks either being declined or trapped in a suboptimal product due to a down-valuation or lender obstacles, it may make sense to delay.

Consider whether you have enough equity to absorb a reduced valuation, or if you are comfortable with potentially higher legal or advisor costs involved in a more complex case. It’s often helpful to run the maths with a broker or financial adviser to weigh the benefits of acting now versus waiting.

Conversely, if service charge increases or Section 20 bills are imminent, now may be a prudent time to consolidate debts or release equity to help meet known costs — provided you can navigate the increased complexity.

Conclusion: Patience, Preparation, and Persistence

Remortgaging a flat in a building undergoing major works is undoubtedly more challenging than in a conventional scenario. However, with careful planning, full disclosure, and professional guidance, it is not impossible. From preparing your documentation and timing your application carefully, to understanding lender sentiment and working closely with a specialist mortgage broker, there are multiple avenues to navigate the process successfully.

Ultimately, the key lies in balancing timing, transparency, and tactical advice. While the presence of major works can complicate your remortgage journey, it doesn’t have to derail it. With the right strategy and support, flat owners can still secure competitive mortgage terms—even amidst scaffolding, surveys, and service charge upheaval.
