Retrospective structural warranties for homes already started or finished
Started on site without a warranty, or finished and now a buyer's lender is asking for one? It is more common than most developers expect. We place retrospective latent defects cover with specialist underwriters and tell you straight, early on, whether your project is likely to be accepted.

An honest answer, early
Retrospective cover is very hard to place, so we tell you quickly whether it is likely to be possible and what a provider will need to see - and we do our best to find you cover.
Where are you now?
Retrospective warranty cover for your situation
No two late warranty cases are quite the same. Pick the one closest to yours to see how cover works, what providers look for and what to do first.
Already started on site
Work is under way and nobody registered a warranty. The sooner a provider sees the site, the more it can inspect for itself.
Warranty after work has started
Finished with no warranty
The building is complete, often a smaller scheme, and a warranty was never arranged. Some specialist providers will still consider it.
Warranty for a completed building
Cannot sell or remortgage
A buyer's lender, or your own, wants a warranty you do not have. We look at whether retrospective cover could keep the deal alive.
When a lender wants a warranty
Evidence and surveys
Building control records, dated photographs, site reports and opening up - what providers ask for, and why it matters so much.
Retrospective warranty evidence
Architect's certificate only
Signed off with a professional consultant's certificate, and now a lender or funder wants a warranty instead.
Certificate or warranty
Stalled or taken-over sites
A project that stopped for a year or more, or a site picked up after the first developer went into liquidation.

Late cover is a different job from registering at the start
A structural warranty protects buyers, owners and lenders against serious defects in the structure for 10 or 12 years. When it is registered before work starts, the provider's surveyor sees each key stage go in. When it is arranged late, the provider has to be satisfied about work it never saw.
- Fewer providers will look at it. Many warranty providers only take on projects before the start. We know the specialist underwriters who consider retrospective cases.
- The evidence decides it. Records, photographs and site reports carry the weight. We tell you what is likely to be needed before anyone spends money on surveys.
- An honest answer, early. Some projects will not be accepted. We would rather tell you that in the first conversation than after weeks of waiting.
- The lender has to accept it. A warranty is only worth having if your buyers' mortgage lenders accept the provider. We check that before you commit.

Cost
What does retrospective cover cost?
As a rough guide the total is a percentage of the rebuild cost: around 1.25% for a build already under way and around 1.5% for a finished building, compared with around 1% when cover is registered before the start (plus a modest broker fee, only charged if we arrange your cover).
These are indications, not quotes. The provider sets the price once it has reviewed the project and the evidence.
Questions
What people ask us first
Can I get a structural warranty after work has started?
Often, but not always. Some specialist providers consider projects already under way, subject to evidence of the work done so far and inspections of the stages still to come. It usually costs more than registering before the start, and the provider decides whether to accept it. See warranty after work has started.
Can a completed building get a structural warranty?
Sometimes. A few providers will consider a finished building after a survey and a review of how it was built, and some only look at buildings completed within a limited number of years. See completed buildings.
Is a structural warranty a legal requirement?
There is usually no law that says a new home must have one. In practice most mortgage lenders expect a newly built or converted home to have a warranty from a provider they accept, or in some cases a professional consultant's certificate - which is why a missing warranty so often comes to light during a sale or remortgage.
Are you the insurer?
No. We are an insurance broker. We place your case with specialist warranty providers and insurers, and the provider named in your quotation provides the cover and decides whether to offer it.
