When you’re planning a home renovation, extension, or new build, choosing the right builder is one of the most important decisions you’ll make. Here’s a breakdown of the key guarantees and warranties you should expect when hiring a builder:
1. Workmanship Guarantee
A good builder should provide a workmanship guarantee covering the quality of their work. This usually lasts between 6–24 months depending on the size of the project. It means that if faults or defects appear as a result of poor workmanship, the builder will return to fix them at no extra cost.
2. Manufacturer Warranties
If your project involves materials such as roofing, windows, doors, or kitchen fittings, check that the builder passes on the manufacturer’s warranty. These can last anywhere from 5 years to a lifetime, depending on the product. A reputable builder will also install materials in line with the manufacturer’s guidance, so the warranty stays valid.
3. Structural Warranty
For new builds, extensions, or major structural work, you should ask about a structural warranty (often 10 years). This covers serious defects affecting the foundations, walls, or roof structure. It’s especially important for new homes and may be required by mortgage lenders.
4. Insurance-Backed Guarantee
Sometimes, smaller builders or contractors offer an insurance-backed guarantee. This means that even if the builder ceases trading, you’re still covered. It’s an extra layer of security that ensures your project is protected no matter what happens to the company.
5. Plumbing, Heating & Electrical Warranties
Qualified electricians and gas engineers will typically provide separate certificates and warranties for their work. For example, a Part P certificate for electrical safety or a Gas Safe certificate for heating installations. These not only give you peace of mind but may also be required by law.
6. Aftercare & Snagging
Many reputable builders offer a snagging period—a set time after project completion where you can report small issues, like minor cracks or finishing touches. Having this written into your contract shows the builder stands by their work and values customer satisfaction.
Why Guarantees & Warranties Matter
Building projects are big investments, and guarantees aren’t just paperwork—they’re a sign that your builder is confident in their work. They protect you financially and ensure any problems that arise are resolved quickly and professionally.
