The honest answer

What HMO refurbishment
really costs in London.

Converting a three-bedroom house into a five-bedroom licensable HMO in London costs between £35,000 and £70,000 + VAT. Adding ensuites to every room and pushing to six or seven lettable rooms takes it to £70,000–£130,000+. Bringing an existing HMO up to current fire-safety standards is typically £4,000–£12,000.

The cost drivers are the number of lettable rooms, the fire-safety works (FD30 fire doors with closers and strips, a Grade D LD2 interlinked alarm system, emergency lighting, fire-resistant ceilings and protected escape route), the number of bathrooms and ensuites, kitchen size and appliance count, and whether new stud walls, layout changes or a loft conversion are needed to meet minimum room sizes.

Tom Harvey Contractors provides free site visits and itemised written quotes aligned with the council's HMO standards, and we can work from your licensing officer's schedule or produce one for the application.

Common questions

Your questions
answered.

Converting a three-bedroom house into a five-bedroom licensable HMO costs £35,000–£70,000 + VAT including room reconfiguration, fire-safety works, a second bathroom and an upgraded kitchen. Adding ensuites to every room and reaching six or seven rooms costs £70,000–£130,000+.
Typically FD30 fire doors with self-closers and intumescent strips to all bedrooms and the kitchen, a Grade D LD2 interlinked smoke and heat alarm system, emergency lighting on escape routes, a 30-minute fire-resistant escape route (ceilings and walls), fire blanket and extinguishers, and thumb-turn locks on exit doors. Requirements vary by borough — we work to your council's standard.
The national minimum is 6.51m² for a single adult and 10.22m² for two adults, with many London councils applying higher standards. We measure every room and plan reconfigurations so each lettable room is compliant.
A small HMO (3–6 people) is usually permitted development unless the borough has an Article 4 direction — and many London boroughs do. Larger HMOs (7+) always need planning. Check with the council or your planning consultant before committing; we can quote for the works in parallel.
£5,000–£9,000 + VAT per room including stud walls, plumbing, drainage, ventilation, shower, basin, WC and tiling. Ensuites significantly raise the rent per room and are usually worth it in London.
Licensing standards typically require a set number of cookers, sinks, fridge-freezers and worktop length per number of occupants, plus fire-resistant construction and a fire door. We size the kitchen to the licence and fit durable landlord-spec units and worktops.
A fire-safety upgrade 1–2 weeks. A three- to five-bed conversion 6–10 weeks. A full six- or seven-bed conversion with ensuites 10–16 weeks. We programme around the licence application timeline.
Yes — electrical certificates (EICR/EIC), fire alarm and emergency lighting certificates, gas safety via our Gas Safe engineer, and a schedule of completed works with photos for the licensing officer.
