How Fort Helps Protect Homeowners During UK Renovations

Hiring a builder is a major financial commitment. Whether you are spending £10,000 on a bathroom or £100,000 on an extension, you need to know who you are hiring, what you are paying for and what happens if the work does not go to plan.

Too often, homeowners rely on recommendations, online reviews and verbal assurances, then discover that these offer little practical help when a project stalls, costs increase or work falls below the agreed standard.

Fort helps homeowners manage renovation risk through verified Contractors, Fortified milestone payments, shared project records and a structured dispute-resolution process. Instead of treating finding a builder, managing the work and making payments as separate tasks, Fort brings them together in one place.

Here is how it works and why each part matters.

Why homeowners need better protection

Problems with building work are not limited to isolated cases.

In September 2026, the Federation of Master Builders (FMB) published findings from a nationally representative survey of 2,051 UK adults. It reported that:

• 37% had hired a builder who turned out to be unreliable or unqualified.
• 33% had received poor-quality work.
• 22% had experienced a job being left unfinished.
• 15% had lost money to an unreliable builder over the preceding five years, with an average loss of £1,759 per affected person.

The FMB estimated that these losses amounted to £14.3 billion nationally over five years. This is an estimate extrapolated from survey responses, rather than a direct count of verified losses. Source: FMB, September 2026.

Citizens Advice has also reported substantial numbers of complaints about home improvement work. Between July 2024 and June 2025, its Consumer Service received 36,534 complaints relating to home maintenance and improvements. Of these, 19,281 concerned substandard services, while 5,230 involved scams or rogue traders. These figures represent complaints received by the service, not every problem experienced by UK homeowners. Source: Citizens Advice, August 2025.

The issue is not simply finding someone who appears trustworthy. Homeowners also need a clear agreement, a sensible payment structure and a reliable record of what happens throughout the project.

Where protection can fall short

Several problems commonly leave homeowners exposed during a renovation.

Paying too much before the work is completed

A large upfront payment can leave a homeowner out of pocket if the contractor stops work, fails to deliver or becomes uncontactable. Recovering money may be difficult, particularly if the contractor has financial problems.

Unclear agreements

If the scope, materials, finish and payment terms are not documented properly, disagreements can develop over what the builder was expected to do and what the original price covered.

Poor records

Plans, photographs, invoices, messages and agreed changes are often spread across emails, messaging apps and paper documents. Reconstructing the agreement becomes harder when a dispute arises.

Relying on a listing or review alone

Recommendations and reviews can help homeowners choose a contractor, but they do not necessarily protect payments or resolve a disagreement.

The Competition and Markets Authority (CMA) has highlighted the importance of accurate claims, appropriate trader checks, effective complaints processes, monitoring and action when problems arise on trader recommendation platforms. Its guidance was updated in May 2026 following further compliance work with platforms. Source: CMA guidance on trader recommendation platforms.

These are different risks, and no single check eliminates them all. Fort is designed to address several of them together.

1. Find Contractors who have been checked

Fort's verification process provides an additional layer of checks before Contractors can become Fort Certified.

The process includes identity verification through Stripe during payment account setup, insurance checks as required by Fort and further business and financial review.

This gives homeowners more information than an unverified listing alone. However, verification is not a guarantee that every project will go smoothly or that a contractor will never have a problem.

You should still check relevant qualifications, insurance, references and previous work. Confirm who is legally responsible for the project and make sure the written agreement identifies the correct person or company.

Our UK builder-vetting checklist explains the checks worth making before appointing a contractor.

Fort's checks provide an additional layer of confidence, not a substitute for your own due diligence.

2. Keep payments aligned with progress

This is one of the most important ways Fort helps homeowners manage financial risk.

With conventional payment arrangements, a customer might pay a large deposit or settle an invoice before much of the corresponding work has been completed. If the project subsequently stalls, the homeowner may have to find additional money to finish the job while trying to recover what was paid.

Fortified milestone payments structure the project into defined stages. You and your contractor agree the work and the amount associated with each stage before it begins.

Funds for the relevant milestone are secured before work starts and released when the agreed stage is completed, in accordance with Fort's payment process.

This creates a clearer link between the payment and the work it covers. Your contractor can see that the agreed funds have been secured, while you retain a defined completion requirement for that stage.

Fort also sets limits designed to keep milestones manageable:

• 45 days maximum per milestone. Longer projects can be divided into shorter stages or substages.
• £10,000 maximum per secure bank payment. A milestone without substages, or each individual substage, must stay within that limit. Larger packages of work can be split into substages.

These are Fort's platform rules, not general construction regulations.

Milestone payments cannot eliminate every risk. Unexpected problems can still occur, and both parties need to agree the scope and completion criteria carefully. However, the structure reduces the need to commit the full project cost upfront.

3. Keep your project information in one place

Payments are only one part of a successful renovation. You also need to keep track of what was agreed, what has changed and what has been completed.

Fort helps you organise relevant project information, documents, communications, milestones and approved variations in one place.

This is useful when the original plans change or additional work is requested. Rather than relying on a verbal conversation or searching through old messages, both parties can refer to the documented agreement.

For example, suppose you decide to upgrade the windows partway through an extension. The change may affect the price, materials and timescale. Recording the variation and agreeing its cost before proceeding gives both parties a clearer understanding of the revised project.

This also helps when reviewing milestone completion. The agreed scope and supporting project records provide a reference point for determining what was required at each stage.

Our guide to the hidden costs of home renovation explains why unclear inclusions and undocumented changes can lead to unexpected expenses.

4. Have a structured route if something goes wrong

Most homeowners start a renovation expecting the work to be completed as agreed. But if a project stalls or a dispute develops, it helps to have a clear record and an established process for addressing the problem.

Fort provides a structured dispute-resolution process linked to the project and its milestone payments.

The process can draw on the agreed scope, milestone details, photographs, documents and project communications already held on the platform. Where appropriate, Fort can arrange for an independent third-party chartered surveyor to assess the work against the agreed project information.

This can provide a more structured starting point for resolving disagreements about completion or the standard of work.

It is important to understand the limits. Fort cannot guarantee that every dispute will be resolved in your favour, that a contractor will complete the job or that you will recover every loss. Legal rights and obligations still depend on the agreement and the circumstances.

The advantage is having a documented project and a defined process to follow, rather than trying to piece together what happened after the event.

If your main concern is a contractor disappearing partway through construction, read our guide to what happens if a builder disappears mid-project.

5. Use Fort with a builder you already know

You do not have to find your contractor through Fort to benefit from its project tools.

You can create a project and invite an existing builder, including for work that has already started, subject to the applicable platform requirements.

This means you can continue working with a contractor you trust while using Fort to organise relevant project information, agreed milestones and payments.

For example, if you have already appointed a builder for a kitchen extension, you can discuss bringing the project onto Fort so you and the contractor can agree how the remaining work, records and payment stages will be managed.

Introducing Fort partway through a project does not automatically change the original contract or protect payments already made. Any revised arrangements should be agreed by both parties, and you should understand which work and payments are covered.

You can find the details on Fort's homeowner page.

A practical example: protecting a £20,000 renovation

Consider a hypothetical renovation budget of £20,000, divided into four agreed stages of £5,000 each.

Under an arrangement where the homeowner pays a £5,000 stage directly to the contractor upfront, that money has already left the homeowner's hands before the stage is completed. If the work subsequently stops or is disputed, recovering the payment may become a separate problem.

With Fort's milestone model, the £5,000 for the relevant stage is secured before work begins, with release linked to completion of the agreed milestone.

If progress is disputed, the agreed scope and project records provide a basis for addressing the issue through Fort's process. The milestone structure also means that the entire £20,000 project budget is not necessarily paid out at the beginning.

This example illustrates the payment structure, not a guarantee of recovery. Fort's protection depends on the agreed arrangements, and a dispute may still take time to resolve.

The objective is to limit how much money is exposed at any one stage and make the link between payment and progress clearer.

What Fort does not replace

Good project management should include more than a platform.

Before construction begins, homeowners should still:

• Check the builder's identity, references, qualifications and appropriate insurance.
• Agree a written contract covering scope, price, timescale and payment terms.
• Confirm who is responsible for planning permission, Building Regulations and other necessary approvals.
• Keep their own copies of important documents and payment records.
• Seek independent legal, surveying or technical advice where the project or dispute warrants it.

Fort supports these arrangements, but it does not replace a properly drafted contract, professional inspections, building control or independent advice.

How to get started with Fort

If you are planning a renovation, the best time to organise the agreement and payment arrangements is before the work begins.

Fort brings together trade verification, milestone payments, project records and a structured dispute-resolution process to help homeowners manage the project more clearly.

You can post a project and connect with Contractors on the platform, or invite an existing contractor to use Fort for an agreed project.

Whether you are renovating a bathroom, extending your home or managing a much larger refurbishment, Fort helps you organise the work, document agreements and link payments to defined stages.

Frequently asked questions

Does Fort guarantee that a builder will finish my project?

No. Fort's verification checks and project tools are designed to reduce risk, not eliminate it. Milestone payments, documented agreements and a structured dispute process can help manage problems if they arise, but they cannot guarantee project completion.

Are Contractors on Fort vetted?

Yes. Contractors undergo Fort's verification process, which includes identity verification through Stripe during payment setup, insurance checks as required and further business and financial review. Homeowners should still check references, relevant qualifications and the contractor's suitability for the work.

How do Fortified milestone payments work?

The homeowner and contractor agree defined stages of work and the amount associated with each one. Funds for a milestone are secured before that stage begins and released when the agreed work is completed, in accordance with Fort's payment process. Milestones can last up to 45 days, and each secure bank payment is capped at £10,000 per stage without substages, or per substage.

Can I use Fort with my existing builder?

Yes. You can invite a builder you already know to use Fort for an agreed project. If work has already started, discuss which remaining stages, records and payments will be brought onto the platform. Existing agreements and payments are not automatically changed by joining.

What happens if I have a dispute with my builder?

Fort provides a structured dispute-resolution process that can use the project's records and milestone information. Where appropriate, a third-party chartered surveyor can be arranged to assess the work against the agreed project information. The outcome will depend on the circumstances and applicable agreements.

Final thoughts

Home renovation involves financial risk, but the way a project is organised can make a meaningful difference.

Choosing a suitable contractor, agreeing the scope in writing, keeping accurate records and structuring payments around completed work all help establish clearer expectations from the start.

Fort brings these elements together through verified Contractors, Fortified milestone payments, shared project information and a structured dispute-resolution process. It cannot prevent every problem, but it gives homeowners a clearer framework for managing their renovation and addressing issues if they arise.

Protect your project by putting the right structure in place before the work begins.
