Letting a home in London is a business, and the landlords who do best treat it like one: they know their numbers, they respect the law, they pick tenants on evidence rather than instinct, and they spend money on the property when spending it matters. This guide is the handbook we work from, written out in full. It assumes nothing and flatters nothing. Where the law sets the rules, we say so; where there is judgement, we tell you ours.

First decisions: let or sell, and what your home really rents for

Start with the honest question: do you want to be a landlord, or do you want to have been one? Letting suits people comfortable with a medium-term hold — five years minimum makes the friction worthwhile. If your horizon is shorter than that, or the property needs works you cannot fund, selling may be the better business decision, and a good agent will say so. We would rather tell you that at valuation than watch a stressful year unfold.

The rent question deserves better than a portal search. Automated estimates ignore condition, floor, layout, timing and the simple fact that two flats on the same street can differ by fifteen percent in what they actually let for. A proper valuation shows you the comparable homes — addresses, dates, achieved rents — and explains where yours sits. Ask any agent for exactly that. If they will not show comparables, they are quoting a number designed to win your signature, not to let your home.

Timing matters too. The lettings market runs in seasons: the serious demand curve peaks in late summer and again in the new year, softens in the autumn, and goes quiet in December. If your property is ready in July, you are renting into strength. If it is ready in November, price for the season or wait for January; a month empty costs more than most rent reductions ever will.

Preparing the property

Tenants rent homes, not square footage. The preparations that pay fall into three buckets. The first is safety and legality, which is not optional: a valid EPC rated E or above, a gas safety certificate if you have gas, a recent electrical inspection report, smoke alarms on every storey, carbon monoxide alarms wherever there is a fixed combustion appliance, and locks that open without keys from the inside. We audit all of it before marketing, because a compliance problem discovered mid-tenancy costs ten times what it costs at the start.

The second bucket is presentation. Clean beats renovated: a deep clean, worn carpets replaced rather than cleaned, walls in neutral paint, every lightbulb working, and the garden cut back. Photographs decide viewing numbers, and photographs flatter nothing — a weekend of preparation shows in every frame. Repairs that signal neglect, like the dripping tap and the cracked window pane, matter more than upgrades; tenants price neglect as a landlord who will not fix the boiler either.

The third bucket is furnishing decisions. Unfurnished lets more easily to the family market and reduces your maintenance surface; furnished commands higher rents in the flat market and moves faster, but the furniture is now your inventory to maintain. Whatever you choose, the tenancy agreement must match, and the inventory must record every item's condition. Do not leave a “few bits” — partial furnishing confuses checkout arguments more than anything else we see.

Choosing a service level

Be honest about your appetite. Tenant find suits the hands-on landlord: local, responsive, happy to coordinate trades and chase the occasional late payment. The agent's job ends at move-in; from there the tenancy is your project, and the fee reflects that.

Rent collection adds the money mechanics: rent collected, arrears chased from day one, statements that itemise everything. It suits landlords comfortable with maintenance and communication but wary of becoming a debt collector — a sensible boundary, because arrears handled personally are arrears handled emotionally.

Full management is the choice of most of our landlords, particularly those with full-time jobs, more than one property, or an address outside the M25. The agent becomes the single point of contact for tenants, the keeper of the compliance calendar, the manager of inspections and repairs, and the negotiator of renewals. The fee is the highest of the three and, in our experience, the best value in the market — one avoided emergency call-out at midnight usually pays the difference for a quarter.

Whatever level you choose, ask the agent three questions: who exactly will handle my property, what are your arrears and compliance processes in writing, and show me a sample monthly statement. The answers, or the wince, will tell you everything.

The compliance stack

England's landlord obligations are a stack, and each layer has a penalty behind it. The deposit must be protected with a government-approved scheme within thirty days, with the prescribed information served, or the tenant can claim up to three times the deposit. Gas safety requires an annual certificate from a Gas Safe engineer, a copy served to tenants within twenty-eight days. The electrical installation must be inspected at least every five years with a satisfactory EICR, and any C1 or C2 findings remedied. The EPC must be band E or better to let at all, and efficiency rules keep tightening, so plan improvements ahead of the requirement rather than behind it.

Right to rent checks apply in England to every adult occupant, with documents recorded and visa expiries diarised for recheck. Smoke alarms must be on every storey and carbon monoxide alarms in rooms with fixed combustion appliances, tested at the start of each tenancy. Depending on the borough, selective or additional licensing may apply to the property; letting without one in a licensed area is a civil offence with fines to match. And the Renters' Rights Act's reforms are phasing in around us — periodic tenancies, the end of no-fault evictions under section 21, and stronger renter protections — the biggest change to the landlord-tenant relationship in a generation, and one we are tracking line by line for our landlords.

Money: rent, taxes and reserves

Run the numbers like the business it is. Gross yield is rent times twelve divided by the property's value; real yield subtracts the honest costs — agent fees, compliance renewals, maintenance at one to one-and-a-half percent of value per year on average, voids at four to six weeks a year in a normal market, and insurance. If the honest number still works against your alternative uses of the capital, let it; if it does not, sell it. The landlords who suffer are the ones who never wrote the number down.

Taxes deserve their own sentence: rental profit is income, the finance-cost restriction phases in for higher-rate taxpayers, and non-resident landlords should register for the non-resident landlord scheme so rent can be paid gross where appropriate. We are not tax advisers and this is not tax advice, but we will produce the statements and year-end summaries your accountant needs, which is half the pain already solved.

Keep a reserve. The boiler you replaced “early” was cheap; the one replaced in a January cold snap, with tenants in situ and a fixed term running, costs what it costs. One percent of property value per year, sitting somewhere boring, is the difference between maintenance being a process and maintenance being an emergency.

Choosing and keeping tenants

Reference on evidence: affordability at roughly two-and-a-half to three times annual rent, credit history, employment verification, and a previous landlord's reference that you have actually read. Right-to-rent documents verified before keys move. Guarantors for students and thin files, with the guarantee explained to the guarantor in plain words. That is the whole science, and every shortcut in it — the skipped reference, the “seemed trustworthy” — is a story that ends at a possession claim.

Keeping a good tenant is cheaper than finding one, so treat renewals as events. Review rent against comparables every year; if the market has not moved, say so and bank the loyalty instead. Respond to repair requests within a day, even when the answer is “booked for Thursday”. Give notice for visits. Small things, endlessly repeated, are why our managed tenancies average longer than the market — and why the rent reviews our landlords do make are accepted without a fight.

Renewals, endings and deposits

Endings start two months out, with a renewal conversation or a notice served properly. When a tenancy ends, the checkout inspection runs against the move-in inventory, and any deduction proposal carries its evidence: photos, reports, invoices. Deposit disputes go to the scheme's free adjudication, and landlords who propose only what their documents support win the overwhelming majority of them. The discipline that protects the deposit is the same one that protects the relationship all the way through: write everything down, and never take the last month personally.

Re-letting starts the same week: marketing while the property is at its best, works scheduled between tenancies, and the lessons of the last tenancy — the shelf that broke, the radiator that never warmed — fixed while the walls are open. A week of preparation between tenancies is worth a month of trouble within one.

The best compliment a landlord can get is a tenant who renews, and the second best is a tenant who leaves the property better than the inventory found it. Both are bought with the same currency: maintenance answered fast, rules applied evenly, and money talked about in writing.— The H1 Housing management desk
