HMO Conversions in Trafford

Last updated 08/26 · 9 minute read · Renovat Construction

Converting a house into an HMO in Trafford always needs full planning permission. A borough wide Article 4 direction has been in force since 21 December 2017, which removed the permitted development right to change a family home (Use Class C3) into a small HMO (Use Class C4). There are no exempt wards. Budget £40,000 to £120,000 for the conversion itself, roughly £8,000 to £15,000 per room, plus a £610 planning application fee and £1,223 in Trafford Council licence fees for a six bedroom property.

The Article 4 direction and what it means for you

Across most of England, converting a family home into a small HMO for three to six unrelated occupants is permitted development. You change the use from Class C3 to Class C4 without asking anyone. Trafford removed that right.

Trafford Council confirmed a borough wide Article 4 direction covering small HMOs, and it took effect on 21 December 2017. Trafford Council lists the control of houses in multiple occupation as one of the two purposes for which it operates Article 4 directions in the borough. Unlike neighbouring authorities that drew their directions around student areas, Trafford applied a single direction across the whole borough. Stretford, Urmston, Sale, Altrincham, Old Trafford, Partington and every ward in between are treated the same way.

The practical effect is simple. If you buy a three bedroom semi in Sale and intend to let it room by room to four tenants, you need planning permission before you do it. Buying first and applying later is the single most expensive mistake investors make in this borough, because the application can be refused.

Two national exceptions still apply:

• Established use. A property lawfully operating as a small HMO before 21 December 2017 retains that use, provided it has not since been returned to single family occupation. Ask for the evidence in writing before you exchange.
• Large HMOs. Any HMO housing seven or more occupants is sui generis under the Town and Country Planning (Use Classes) Order 1987 as amended. It has always required full planning permission everywhere in England, so the Article 4 direction changes nothing for it.

Applying for planning permission in Trafford

The application is a change of use from C3 to C4, which falls under “other changes of use of a building or land” in the statutory fee schedule. The Planning Portal fee for that from 1 April 2026 is £610, plus a Planning Portal service charge of £75.83 plus VAT if you submit online rather than paying the council directly. Drawings and a planning agent typically add £1,500 to £3,500. Allow eight to thirteen weeks for a decision.

What decides the outcome is usually concentration. Planning officers look at how many HMOs already sit within a defined radius of the property. A street that is already dense with shared houses is a difficult application regardless of how well designed your scheme is. Check the surrounding density before you offer on a property, not after.

Trafford also has 22 conservation areas. If the property sits inside one, any visible external change is assessed separately from the change of use. Replacement windows, new rooflights, additional bin storage and rear outbuildings all become planning matters in their own right. A pre-application discussion with Trafford Council is worth the fee on any conservation area property.

HMO licensing and Trafford Council fees

Planning permission and licensing are separate processes handled by different council teams. You need both. Holding a licence does not make the use lawful, and having planning permission does not exempt you from licensing.

Mandatory licensing under the Housing Act 2004 applies to any property occupied by five or more people forming two or more households who share a kitchen, bathroom or toilet. Trafford Council charges the fee in two parts, one on application and one on grant.

Trafford Council fee	Amount	When it is paid
Application for a licence, up to and including 6 bedrooms	£1,012	On application
Each additional bedroom from the 7th onwards	£25	On application
Granting of the licence	£211	On approval
Application to vary an existing licence	£331	On application
Pre-licence application advice	£435	Optional, before applying

Fees published by Trafford Council. Confirm current amounts with the Housing Standards team before applying.

A six bedroom HMO in Trafford therefore costs £1,223 in council licence fees. Licences run for up to five years and do not renew automatically. Operating without one is a criminal offence and exposes you to an unlimited fine and a rent repayment order.

Trafford operates mandatory licensing only. It has not designated additional or selective licensing areas, though councils must consult before introducing them, so check the position for your address before you buy.

You will need to submit a full document pack with the application, including a plan showing every room measurement, a fire alarm commissioning certificate, emergency lighting certificate, gas safety certificate, an electrical installation condition report, the tenancy agreement and a basic DBS certificate obtained within the previous six months.

Room sizes and amenity standards

Minimum sleeping room sizes are set nationally by The Licensing of Houses in Multiple Occupation (Mandatory Conditions of Licences) (England) Regulations 2018 and apply to every licensed HMO in England.

Occupancy	Minimum floor area
One adult	6.51 square metres
Two adults sharing	10.22 square metres
Cannot be used for sleeping at all	Under 4.64 square metres

Measure every room before you offer on a property. Trafford has a large stock of 1930s semis in Sale, Urmston and Flixton whose third bedroom sits very close to the 6.51 square metre threshold. A box room that fails is a room you cannot let, which changes the yield calculation entirely.

What an HMO conversion costs in Trafford

Most HMO conversions across Trafford run from £40,000 to £120,000 depending on room count, the condition of the property and the specification. On a per room basis, expect £8,000 to £15,000 per room for a mid specification finish, with ensuites pushing towards the upper end.

The elements that move the number most:

• Fire compartmentation. Fire doors to every room, a mains linked alarm system to the correct grade, emergency lighting and a protected escape route. This is not optional and it is not cheap.
• Ensuites. Each one adds drainage, ventilation and waterproofing. They command higher rent but they are the single biggest cost driver per room.
• Rewiring and consumer unit. Older Trafford stock frequently needs a full rewire to satisfy the electrical installation condition report the licence application requires.
• Structural alterations. Moving walls to make a failing box room compliant, or forming a room from a cellar or garage.
• Kitchen provision. Amenity standards scale with occupancy, so a six bed scheme often needs a second cooking point.

Add the £610 planning fee, £1,500 to £3,500 in drawings and agent fees, and £1,223 in Trafford licence fees on top of the build cost. See our full HMO conversion cost breakdown for a room by room analysis.

Where HMO conversions work across the borough

Because the Article 4 direction is borough wide, the planning position is identical everywhere in Trafford. What differs is the property stock, the tenant market and the existing HMO density.

• Old Trafford and Stretford. Victorian and Edwardian terraces with the room counts that suit shared housing, strong transport links into the city centre, and the highest existing HMO concentration in the borough. Density is the thing to check here.
• Sale and Urmston. Larger 1930s semis and professional tenants. Higher purchase prices, better room sizes, lower existing density.
• Altrincham and Bowdon. Substantial period properties that convert well, but purchase prices and conservation area constraints both bite. See our dedicated guide to HMO conversions in Altrincham.
• Partington and Broadheath. Lower entry prices and a different tenant profile. Run the rent figures carefully before committing.

Frequently asked questions

Do I need planning permission for an HMO in Trafford?

Yes. Trafford has a borough wide Article 4 direction in force since 21 December 2017 which removed the permitted development right to convert a C3 dwelling into a C4 small HMO. Every conversion needs a full planning application, and there are no exempt wards. The only exception is a property whose HMO use was lawfully established before that date and has not since reverted to single family occupation.

How much does an HMO licence cost in Trafford?

Trafford Council charges £1,012 on application for a property of up to six bedrooms, with an extra £25 for each bedroom from the seventh onwards, and a further £211 when the licence is granted. A six bedroom HMO therefore costs £1,223 in total. Varying an existing licence costs £331 and optional pre-application advice costs £435.

How long does an HMO conversion take in Trafford?

Allow eight to thirteen weeks for the planning decision, then eight to sixteen weeks on site depending on room count and the extent of structural work. Licensing runs alongside the build. From offer accepted to first tenant, a realistic programme for a five or six bed conversion in Trafford is six to nine months.

Can Trafford Council refuse my HMO planning application?

Yes, and refusals are common where the existing concentration of HMOs on the street or within the surrounding area is already high. This is the main reason to check density and planning history before exchanging on a property rather than after. If refused, you can appeal to the Planning Inspectorate, but a refusal leaves you holding a property you cannot use as intended.

What is the minimum room size for an HMO in Trafford?

The national minimums apply: 6.51 square metres for a room slept in by one adult, and 10.22 square metres for two adults sharing. Any room under 4.64 square metres cannot be used for sleeping at all. These are set by The Licensing of Houses in Multiple Occupation (Mandatory Conditions of Licences) (England) Regulations 2018, not by Trafford Council, so they cannot be negotiated.

Does Trafford have additional or selective licensing?

Trafford operates mandatory HMO licensing only, which covers properties occupied by five or more people forming two or more households who share facilities. It has not designated additional or selective licensing areas. Councils must consult before introducing new schemes, so confirm the current position with Trafford Council’s Housing Standards team before buying.
