Full turnkey HMO conversions, every trade in-house.
Wolsten are specialist HMO conversion contractors serving Bolton, Wigan, Manchester, Bury, Preston and the wider North West. With over 60 years of combined construction experience and 7 years of dedicated HMO conversion work, our family-run team delivers full turnkey HMO projects — from initial feasibility and planning through to a compliant, tenantable property ready to generate income.
We have completed HMO conversions of all types and scales, from a 3-bedroom residential property converted into a fully en-suite 5-bed HMO, to a full-scale pub-to-HMO conversion creating 12 individual units. Whether you are an experienced portfolio investor or approaching your first HMO project, our team will guide you through every stage with honest, expert advice.
All trades are carried out in-house — structural, electrical, plumbing, fire safety, plastering and finishing. One team, one contract, one point of contact throughout.
Compliance first Built in
We don't bolt fire safety on at the end — FD30 doors, interlinked detection, compartmentation and escape routes are designed in from day one, so licensing is straightforward at handover.
Planning handled Article 4
Bolton, Wigan and Manchester all now require planning permission for every HMO conversion. We prepare and manage the full application — and tell you honestly what's likely to be approved before you commit.
Investor-direct Repeat clients
We work with repeat clients including specialist HMO sourcing and investment companies across the North West. Repeat business from experienced investors is the strongest endorsement we can have.
Every type of HMO conversion in the North West.
From a 3-bed terrace to a full commercial building — we've converted them all, with every trade in-house.
Residential to HMO
The most common the North West project: a standard house reconfigured into a licensed HMO. Layout redesign, room additions, full fire safety compliance and building regulations sign-off — handled end-to-end.
Pub to HMO
Former pubs offer outstanding potential — large floor plates, high ceilings, commercial-grade construction. Our largest single project converted a pub into 12 self-contained HMO units.
Commercial to HMO
Offices, retail and light industrial buildings, often available at attractive prices. Change of use planning is always required — an area where our experience gives investors a clear advantage.
Purpose Built HMO
Design the optimal layout from day one: maximum room count, en suite provision, communal space and fire safety built in from the outset, for maximum rental yield from first tenancy.
Article 4 across the North West — the current picture.
Article 4 Directions have changed fast since mid-2025. Here's where each area stands — and remember: an Article 4 area doesn't mean automatic refusal, it means a planning application we prepare and manage for you. We verify your specific property's status as part of the free consultation.
HMO conversion costs — honest, itemised, written.
Guide figures for North West investors in 2026. Every HMO conversion is different — we always carry out a free site visit before providing a full, itemised quote, so you have accurate numbers before committing to anything.
Small HMO
Fire doors, electrical upgrades, bathroom refurbishment and redecoration — minimal structural work. The fastest route to a compliant, lettable property.
Medium HMO
Layout changes, additional bathrooms or en suites, kitchen upgrades and mandatory licensing compliance designed in from day one.
Large HMO
Full structural alterations, fire compartmentation, potential loft conversion or extension to maximise room count and yield.
Fire safety, designed in from day one.
Fire safety is the most critical element of any HMO conversion — and the fastest way to fail a licensing inspection. We don't bolt it on at the end; it's designed into the layout before a wall moves.
FD30 Fire Doors
30-minute fire-rated doors to every habitable room, kitchen and bathroom — certified doors, frames and ironmongery, supplied and installed.
Interlinked Smoke & Heat Detection
Mains-wired, interlinked systems in all rooms and communal areas, installed and tested by our in-house electrical team before handover.
Emergency Lighting
Required in all communal areas, hallways and stairwells — designed and installed in-house to building regulations standards.
Fire Compartmentation
Walls, floors and ceilings to the required fire-resistance ratings, including cavity barriers and fire stopping throughout.
Protected Escape Routes
Clearly defined, protected escape routes designed into the layout from day one — not retrofitted at the end.
Building Control Sign-Off
Every fire safety element signed off by building control before handover. We manage the full building regulations process.

“I worked with Liam and the team on a HMO conversion in Preston. We rewired the full house ensuring all emergency lighting and smoke detector systems were to regulations. We also installed Arc Fault Detection Devices to ensure additional protection for the electrical services. It was a pleasure to work with them and everything went smoothly — I would have no problem doing work for Liam and the team again.”

HMO conversions — straight answers.
How long does an HMO conversion take?
Timescales vary by project size. A small residential conversion (3-4 rooms, minimal structural work) typically takes 4-8 weeks. A medium conversion with layout changes and additional bathrooms usually takes 8-16 weeks. Large or commercial conversions can take 4-6 months. We provide a detailed programme of works before the build starts.
Do I need planning permission for an HMO in the North West?
It depends on your location, though the landscape has changed significantly since mid-2025. Bolton Council introduced a borough-wide Article 4 Direction in June 2025, and Wigan Council — covering areas including Leigh and Atherton — followed with a borough-wide direction in August 2025. Manchester has required planning permission citywide since 2011. Areas such as Bury and Radcliffe do not currently have Article 4 Directions in place, meaning most small conversions there still proceed under Permitted Development rights. We check your specific postcode as part of your free consultation.
What is the difference between HMO planning permission and HMO licensing?
Planning permission relates to the change of use of the property and is dealt with by the local planning authority. HMO licensing is a separate process managed by your local council's housing team, covering safety standards, room sizes and management requirements. Both may be required — we guide you through both as part of our service.
What is the minimum room size for an HMO?
The national minimum is 6.51 square metres for a room used by a single adult. Some local authorities apply stricter minimums. We design all HMO layouts to meet or exceed the requirements of your specific local authority, ensuring no rooms fall below the threshold at the licensing stage.
What areas of the North West do you cover for HMO conversions?
We carry out HMO conversions across the wider North West, including Bolton, Wigan, Manchester, Bury, Preston, Leigh, Atherton, Westhoughton, Horwich, Radcliffe, Tyldesley, Little Lever and Over Hulton. Each area has its own planning and licensing requirements — see the area pages above for local detail, or get in touch and we'll confirm coverage and accurate planning information for your specific location.
Do you manage the licensing application?
We don't submit the licence application on your behalf as this is the landlord's legal responsibility, but we ensure the completed property meets all licensing conditions so your application is straightforward. We can advise on the process and point you to the relevant local authority contacts.
