HMO conversions, built to licence .
HMO conversions and refurbishments across Cheshire and the wider North West. Compliant fire strategy, room sizing, multiple bathrooms and certified electrics — delivered to a standard that passes local-authority licensing first time.
Compliance is not a corner to cut.
The fastest way to lose money on an HMO is to build it now and have to pull it apart later. Inadequate fire doors, undersized rooms, the wrong number of bathrooms — any one of these means a licence refusal or a remediation bill. We build HMOs to local-authority standard from day one.
We work for landlords and investors across Cheshire and the wider North West, deliver to a fixed programme, and hand over the documentation pack the licensing officer wants to see — EICRs, gas safety, fire-detection commissioning and building-control sign-off.

HMO Conversion FAQs.
The questions landlords and investors ask us most often before commissioning a conversion.
Do you handle the HMO licence application?
We work alongside your appointed letting agent or licensing consultant — we don't submit the licence ourselves, but we deliver the build to a standard that meets local authority licensing requirements first time. Most of our HMO clients use a specialist consultant for the application.
How much does an HMO conversion cost?
A typical 4–6 bed HMO conversion (existing house, no major extension) runs £45,000–£95,000 depending on the structural work, kitchen and bathroom counts, and fire-strategy requirements. Larger 7-bed-plus or sui-generis schemes can exceed £140,000.
What does the fire strategy involve?
FD30 fire doors with intumescent strips and self-closers, mains-interlinked smoke and heat detection, fire-resistant plasterboard upgrades, protected staircase and clear means of escape. We work to LACORS / local-authority HMO guidance.
How long does a conversion take?
Typical programme is 10–18 weeks on site, depending on the existing layout, the number of new bathrooms and the extent of structural changes. Strip-out and first-fix usually run 6–8 weeks; second-fix and finishing the rest.
Do you work for landlords and investors?
Yes — most of our HMO clients are landlords or investors operating across the North West. We'll deliver to brief and budget on a tight programme, with a written workmanship guarantee on completion.
