What Exactly is a Warranty?
It’s a specialised insurance product that covers the first ten years in the life of a new house. In many ways, it’s similar to the guarantee you might get when you buy a new car or an appliance. If there is something fundamentally wrong with your house – walls cracking, penetrating damp, drains not working properly – the warranty provider will fix it instead of you having to chase up builders, engineers or architects.
Technically, it’s known as ‘latent defects insurance’. The warranty provider will check your plans and inspect the house (known as a technical audit) while under construction.
Isn’t This All Covered By Regular Building Inspections?
In theory, yes. In practice, the two systems of inspection operate side by side and are concerned with slightly different areas. Besides, if things go wrong, you can’t make a claim against your building inspector.
Local authority building inspectors have recently begun to offer their own warranty scheme (see LABC), but it’s administered independently and uses different inspectors.
How Long Does Cover Last?
Usually for 10 years. And some warranties provide more cover in years one and two than they do in subsequent years.
A warranty is almost invariably charged as a single premium and costs vary from £1,000 up to £5,000, depending on the size and complexity of the project. The average cost for a warranty is £2,000.
Why Doesn’t Household Insurance Cover These Risks?
New homes present some significant risks which usually appear in the first two years after completion, and a warranty is the normal method of covering these risks.
Do I Have to Have One?
It’s not compulsory, but most lenders will require one, and you may have trouble selling a house less than ten years old if you don’t have a warranty in place.
Some people choose to build with an architect’s certificate instead of a warranty — here, the architect certifies that the work has been properly designed and carried out correctly, and provides insurance cover using their own indemnity insurance. But if there is a fault, the self builder then needs to sue their architect, which is expensive and unpleasant. In contrast, a warranty provider deals with the problem like a normal insurance claim.
An Architect’s Guarantee
Some self builders opt for an architect’s certificate over a warranty, which is a signed statement confirming that the house has been supervised during the build period and constructed in accordance with accepted building practices. It’s cheaper than a warranty, in the region of £1,000, but is only valid for six years and is not an insurance policy, meaning if something goes wrong, you would have to prove negligence and claim against the architect’s professional indemnity insurance.
It also doesn’t provide any cover for the insolvency of the builder. An increasing number of lenders are asking for a full structural warranty to be in place before releasing funds.
Who Sells Warranties?
It’s a small, specialised market and the big household insurers won’t be much help, but nevertheless there are enough providers for the market to be quite competitive:
- LABC (Local Authority Building Control)
- Self-build Zone
- BuildCare Structural Warranty
- Protek Selfbuild Structural Warranty
- ProAktive Selfbuild Warranty
How Do They Compare?
Warranty providers often work hand in hand with private building inspectors and offer a range of services over and above warranties and site inspections, such as site insurances, air-pressure testing and SAP calculations. Self-build Zone in particular has set itself up as a one-stop shop for dealing with much of the red tape bedevilling the typical self build project. BLP tends to specialise in larger projects, especially where there are unusual features or modern methods of construction.
There are also brokers, such as Evolution Insurance (01799 512 039), who specialise in the home warranty market and will search out the best deal for you.
When Should I Buy a Self Build Warranty?
It is best to purchase your warranty at an early stage. It needs to be bought at least a couple of weeks before you start on site so that the provider’s inspectors can audit the design drawings prior to the build going on site.
If your warranty provider arranges the building control too, they will need to serve an Initial Notice on the local authority so that inspections can be sorted. A warranty can be provided retrospectively (even once the build is complete), but the further into the build you are, the more expensive a warranty becomes.
Note: The longer you leave it, the higher the costs will be. Whilst some warranty providers cover a self builder halfway through a project, others wont. If a self builder is at the poured concrete stage before contacting a warranty provider, expect to pay an extra 25%. This rises to 50% if at first floor joist, 75% to wall plate (prior to roof), and 100% if structurally complete.
What if I Want to Sell My Self build with No Warranty?
As lenders have tightened their criteria, this is becoming a more common occurrence. In order to sell, you will need a retrospective warranty. If you fail to take out a warranty during construction but retrospectively decide that you need cover, Self-Build Zone and Protek are the only insurers able to help. They will inspect the property and may be able to offer cover for the remainder of the 10 year period since completion.
What is Covered? What isn’t?
Generally the cover is quite limited: latent defects insurance is really just concerned with major faults in the design or construction of a house, such as subsidence, drain problems or rain penetration. Snagging defects such as sticking doors or creaking floors are usually excluded. It’s well worth checking the small print to see what’s covered and what’s not: items like double-glazing failure and roof tile damage are optional. And, of course, as a rule, the wider the cover, the more expensive the policy.
Is There Anything Else I Need to Know?
Self build warranties often come with a ‘lock-in’ of one or two years which restricts the transfer of the warranty to a new owner. For most self builders, this is not a problem, but it can cause an issue when circumstances change (typically death or divorce). In exceptional cases, the warranty providers have the power to relax the lock-in. Check before you sign up.
Self build Site insurance
Quite distinct from both building inspections and warranties, site insurance looks to cover the risks from the building process itself. Site insurance covers you for accidents on site to people working or visiting. It may also cover for fire damage or theft, depending on the clauses and the exclusions.

Find a Self Build Warranty
Protek are a direct provider of 10 Year Structural Warranties for self build, renovation and conversion projects. The warranty covers defects in the design, workmanship and materials that go into the project if these subsequently prove to be defective and cause major damage down the line.
Without it in place, these issues can often be very expensive to fix. This is why banks and building societies will insist on it being in place for mortgage purposes.
The warranty is provided on the back of a series of inspections on the works and the warranty provider can usually incorporate the provision of Building Control into this technical audit process saving you money. The audit process will ensure your project is designed and built correctly and will help you identify any failures in workmanship along the way.
A typical self build project of around 180m² will usually cost approximately £1,700 including the inspection costs when taken out before works start.
Protek have experienced staff on hand to provide you with the structural warranty cover you need on a self build, renovation or conversion project. Protek can arrange cover at any stage of the project, but sorting it all out early is always the most cost effective solution.
Arranging a quotation is quick and straightforward. You can start the process online and speak to an expert if you prefer.
