Permitted development has opened the door to thousands of commercial-to-residential conversions — but while planning restrictions may be lighter, the risks aren’t. That’s where Protek comes in.
Our Permitted Development Warranty is designed specifically for builders and developers converting commercial buildings into new homes under permitted development rights. Whether you’re transforming an office block, warehouse or retail space, we help protect the structural integrity of your project from day one — giving buyers, lenders and investors the confidence they need.
This specialist cover can include full value reinstatement if required, including consequential damage to existing retained elements. It also ensures every home benefits from technical audits, 10-year protection backed by an ‘A’-rated insurer, and compliance with the Consumer Code for New Homes — offering added consumer confidence at point of sale.
Protek’s permitted development warranty isn’t just about meeting minimums — it’s about delivering peace of mind from start to finish.
Why this warranty
Mortgage lenders often require a recognised 10-year structural warranty, especially on permitted development conversions. Protek’s warranty meets that requirement and helps avoid sales delays.
From the moment the policy begins, your buyers are protected — even if you’re no longer trading. This gives confidence to buyers, investors, and funders.
Every property is inspected during conversion by Protek’s auditing team to ensure structural soundness and policy compliance.
Whether you’re a developer converting a large office block or a builder working on a single retail-to-residential unit, this warranty is designed to flex around your project scope.
Protect your investment and meet lender or funder requirements. The policy provides confidence at resale or refinance and supports asset value.
Gain a competitive edge by offering warranty-backed homes, audited during conversion. Meet consumer protection standards and reduce after-sales disputes.
Buyers get peace of mind knowing their home is backed by a 10-year structural warranty, with extra support from the Consumer Code for New Homes.
