Wolsten are specialist HMO conversion contractors based in Westhoughton, at the heart of Bolton borough. With over 60 years of combined construction experience and 7 years dedicated to HMO conversions, our family-run team delivers full turnkey HMO projects across Bolton — from initial feasibility and planning through to a compliant, tenantable property ready to generate income.

Bolton has strong and sustained demand for quality HMO accommodation, driven by Royal Bolton Hospital, major employers including Warburtons, and a growing professional workforce. The introduction of Article 4 in June 2025 means planning permission is now required for all new HMO conversions across the borough — but it also means the supply of new HMOs is more tightly controlled, which supports rental values for well-positioned existing properties.

Our team has in-depth knowledge of Bolton Council’s planning policies, HMO licensing requirements and the local property market. We manage the full process on your behalf — from planning applications through to building regulations sign-off and licensing compliance.

HMO Conversion Costs in Bolton

The cost of converting a property into an HMO in Bolton varies depending on the size and condition of the property, the number of rooms being created and the level of compliance work required. As a general guide:

• Small HMO (3–4 tenants, minimal structural work): £20,000 – £45,000. Covers fire doors, electrical upgrades, bathroom refurbishment and redecoration.
• Medium HMO (5–6 tenants): £45,000 – £85,000. Includes layout changes, additional bathrooms or en suites, kitchen upgrades and mandatory licensing compliance.
• Large HMO (7+ tenants): £85,000 – £180,000+. Full structural alterations, fire compartmentation, potential loft conversion or extension to maximise room count.

These are guide figures only. Every HMO conversion is different. We provide a full, itemised quote after a free site visit with no obligation to proceed.

Planning Permission & HMO Licensing in Bolton

The planning position in Bolton is summarised in the Article 4 section above. For licensing, the key requirements are:

• Mandatory HMO licensing is required for all properties with 5 or more tenants from 2 or more households — managed by Bolton Metropolitan Borough Council
• Additional licensing schemes may apply in certain areas — we check the specific requirements for your property during the free consultation
• Licence fees typically range from £500–£1,500 for a 5-year licence from the local authority
• Minimum room sizes, fire safety standards and amenity requirements must all be met before a licence will be granted
• We build compliance into the design from day one to ensure the licensing process is straightforward once conversion is complete
