HMO ConversionsOne building, multiple lets

A standard property can become a higher-yielding, fully compliant HMO. As HMO specialists, we handle the Article 4 position and run the strongest route to approval, so it earns more for the landlord, investor or developer behind it.

  • Expert HMO feasibility on any London property
  • Full planning, or an LDC for an existing HMO
  • Compliant layouts that make the most of the space

£27,480 single let → £58,800 as an HMO The same property, let room by room: roughly double the income. The conversion starts with planning. Read our complete London HMO planning guide

Flat ConversionsOne building, multiple homes

More homes to let and more value in the building. We design house-to-flat splits and manage the full application, from first feasibility to decision.

  • More lettable units from one building
  • Feasibility, planning and building regs in one place
  • Existing, unconsented flats made lawful

Change-of-use decisions up 24% in two years London councils decided 2,429 change-of-use applications in the year to June 2026, up from 1,951 two years earlier, while householder applications fell (MHCLG). Read our minimum space standards guide

EnforcementA notice answered properly, fast

An enforcement notice puts a landlord on the clock, and panic makes things worse. We respond quickly: we deal with the council directly and put a proper application or lawful development case behind the property, so the asset is protected and earning again.

  • Fast response to live enforcement cases
  • Retrospective applications and LDCs that make the position lawful
  • Direct dealings with the council, start to finish

1,163 enforcement notices in a year Issued by London councils in the year to June 2026 (MHCLG). The right response, made early, protects the property. Read our HMO enforcement guide

Lawful Development Certificates (LDC)Prove lawfulness, protect the asset

Some of the best-earning properties on your patch were converted years ago, without the paperwork. We get the certificate that makes them official, so refinancing, licensing and sales go through smoothly.

  • Existing HMOs and flats certified as lawful
  • Evidence gathering and the full application, handled
  • A clean certificate that satisfies buyers, lenders and licensing teams

Commercial to ResidentialOffices, shops and other commercial units into homes

Many shops, offices and other commercial buildings can become homes without a full planning application. We assess whether the building qualifies, then manage the right route from start to approval, so the landlord or developer has certainty before they commit.

  • Shops and offices into homes, no size limit since 2024
  • Full feasibility on the exact building, so there are no surprises
  • Full planning handled where it is required

Since 2024, any size can convert Prior approval rates have climbed to about 65% as the route matures.

Frequently asked questions.

Real moments and questions that land on your desk, and what we do with them.

"The landlord's asking if it could earn more as an HMO."

We check the borough's Article 4 position and give you the yield case in plain English.

"The survey's turned up works that never had consent."

We put a retrospective application or a lawful development certificate behind it to avoid future enforcement and compliance issues.

"They applied once, got refused, and gave up."

We read the refusal properly and tell you straight whether a better-designed scheme stands a real chance.

"The council's sent an enforcement letter to the landlord."

Licensing or enforcement, we work out what the letter actually means and deal with the council directly to get the best possible outcome.

"There's no paperwork on the conversion."

A lawful development certificate settles the position, so refinancing, licensing and sales go through smoothly.

"The landlord wants options before deciding whether to sell."

A feasibility review shows what the building could become, so the decision is made on facts.

"The buyer's asking what they could do with the property."

A feasibility review gives them a clear, costed vision they can act on.

"The sale's stuck on a loft that never had permission."

We put a lawful development case behind it, the certainty lenders and buyers ask for.

"I've got a valuation tomorrow on a house with obvious potential."

Walk in knowing exactly what it could become; it's the sharpest pitch in the room.

"The vendor wants more than the comparables support."

Planning potential, properly evidenced, is how an asking price is defended.

"A developer wants the numbers before they'll offer."

We set out the route to approval and the constraints up front, so serious buyers move quickly.

"It's been on the market for months."

A property that isn't selling as it is can sell on what it could be; we build that case with evidence.
