HMO conversion works on a London property by GMAS Group

Landlords · HMO

HMO conversion and licensing works.

Turning a house into a compliant, licensable HMO, or bringing an existing one up to the conditions your council has attached. Fire separation, room sizes, amenities and the certificates that go with them.

What we do

Built to the conditions,
not to a guess.

Licence condition review

You send us the schedule of conditions from the council. We price against it line by line, so nothing gets missed and nothing gets gold-plated.

Fire doors and separation

FD30 and FD30S doors with the correct intumescent strips, seals and closers, plus protecting the escape route and boxing exposed services.

Fire detection

Grade A or D systems with the correct coverage for the layout, installed and certificated to BS 5839 Part 6.

Room sizes and layout

Reconfiguration where a room falls under the statutory minimum, and layout changes that make the amenity ratios work.

Kitchens and bathrooms

Additional or upgraded facilities to meet the amenity standard for the number of occupants.

Emergency lighting

Where the escape route needs it, installed and commissioned with the annual duration test set up.

Compliance certificates

EICR, gas safety and the fire alarm certificate, arranged together so the licence application is not held up waiting on one.

Sound insulation

Floor and party wall treatments where the licence conditions or building control require them.

How it works

From schedule
to sign-off.

Schedule review

Send us the council's conditions or the refusal notice. We read it and price against it, rather than quoting a generic HMO package.

Fixed quote

Every condition priced as a line item, so you can see exactly what each part of the licence is costing you.

Works

Carried out in a sequence that keeps the property lettable as early as possible, with occupied HMOs phased room by room.

Certificates

Every certificate the application needs, issued and sent through together rather than trickling in.

Common questions

Answered
plainly.

Do I need an HMO licence?

Mandatory licensing applies to properties let to five or more people forming two or more households. On top of that, many London boroughs run additional or selective licensing schemes that catch smaller properties, and the schemes change. Check your specific borough, because the answer genuinely differs street by street in London.

What usually fails an HMO inspection?

Fire doors, most often. Wrong rating, missing intumescent strips, no closer, or a door that has been painted so many times it no longer closes into the rebate. After that it is detection coverage, room sizes below the statutory minimum, and amenity ratios.

Can you work on an occupied HMO?

Yes, and most of our HMO work is occupied. We phase it room by room and floor by floor, and agree with you what we tell the tenants and when.

Will you deal with the council?

We will price against their schedule, carry out the works and give you the certificates and photographs. The licence application itself stays with you or your agent, because the council deals with the licence holder.

How long does a conversion take?

A straightforward compliance upgrade on an existing HMO is usually two to four weeks. A full conversion involving layout changes, additional bathrooms and building control is more like eight to sixteen. The survey will tell you which one you have.

Which areas do you cover?

All 32 London boroughs, with a focus on west and south-west London.

Before you apply

What councils look for in an HMO, and where applications stall.

HMO licensing is run borough by borough, so two identical houses either side of a boundary can face different conditions. What does not vary much is where applications stall, and it is almost always fire safety, room sizes or amenity ratios rather than anything exotic.

Fire safety

The protected escape route is the thing inspectors look at first. Correctly rated fire doors that actually close into the rebate, intumescent strips and smoke seals, closers fitted and working, and no exposed services penetrating the protected route. Detection has to suit the layout of the HMO rather than the number of rooms, and it needs its commissioning certificate.

Room sizes and occupancy

There are statutory minimum room sizes for sleeping accommodation in licensed HMOs, and a licence will state the maximum number of occupants per room. A room that falls below the minimum cannot be counted, which changes the economics of the whole property, so it is worth measuring before you buy rather than after.

Amenity standards

Kitchens, bathrooms and WCs have to be provided in a ratio to the number of occupants, and the ratios differ between boroughs. This is the condition that most often turns a compliance job into a building job, because meeting it can mean an additional bathroom rather than a new door.

Getting the paperwork together

Most HMOs need an EICR, a gas safety certificate, a fire alarm certificate and often an emergency lighting certificate, and applications are frequently held up waiting on one of them. We arrange them together so they arrive as a set, with photographs of the works, which is what a licensing officer is looking for when they ask for evidence.

Coverage

Areas we cover.

We take HMO conversion work across all 32 London boroughs. Most of our work is in west London, in Shepherd's Bush, Hammersmith, Fulham, Kensington, Chiswick and White City, and in south west London, in Putney, Wandsworth and Wimbledon. We also work in south east London, in Greenwich, Blackheath and Lewisham.

If your property is outside these areas, call us anyway. We travel across London and will tell you honestly if a job is too far to price properly.
