How to rent out your house quickly in London starts with one uncomfortable truth: every day your property sits empty, you lose between £80 and £150.
For a typical London flat renting at £2,500 per month, a two‑week delay costs you over £1,100. That money never comes back. Yet most landlords waste weeks on slow photos, poor pricing, and legal guesswork.
Book a free rental valuation with Home World Management to see what your London home is worth today. Knowing your property’s true market rent is the first step to avoiding costly voids. This guide gives you a day‑by‑day fast‑let blueprint.
You will learn exactly how to prepare, price, market, and secure a tenant within 14 days without cutting legal corners or leaving money on the table.
I will also show you the trade‑off between renting fast and maximising rent, plus the hidden costs of void periods that most guides ignore.
Part 1: Why “Quickly” Matters More Than You Think
London’s rental market moves fast, but your vacancy clock starts ticking the moment the last tenant leaves. Every extra day empty adds three types of cost:
- Direct lost rent – £80–£150 per day depending on your property.
- Carrying costs – council tax (full rate on empty properties), utilities, and insurance.
- Opportunity cost – a delayed start pushes your next lease end date into a slower season (e.g., letting in December instead of September).
A 14‑day void costs you roughly £1,500 in lost rent alone. A 30‑day void? Over £3,000. That is money you will never recover, no matter how high your eventual rent.
So when someone asks “how to rent out your house quickly in London”, the real question is: how do I minimise vacancy while still attracting a reliable tenant? The answer is a systematic, speed‑first process.
Part 2: The 14‑Day Fast‑Let Blueprint
This timeline assumes you start on a Monday. Adjust days as needed, but keep the sequence tight.
Week 1 – Legal & Physical Preparation
Day 1 – Check your legal “must haves”
Before you market, verify you already have or can get within 48 hours:
- Energy Performance Certificate (EPC) – rating E or above. If expired, book an assessor today. Same‑day or next‑day visits cost £60–£120.
- Gas safety certificate – annual check by a Gas Safe engineer. If due, book now. Engineers often offer 24‑hour slots.
- Electrical Installation Condition Report (EICR) – valid for 5 years. If missing, book a qualified electrician. Priority service costs £150–£300.
- Smoke alarms on every floor and CO alarms near solid fuel appliances.
- Right to Rent documents ready – you will need to see originals later, but know the process.
If you need any of these, pay for express service. The £100–£200 extra saves you weeks of delay.
Day 2 – Pre‑qualify your property for speed
Answer three questions: Is the property clean and safe? Are all repairs done? Does it meet local licensing rules? Some London boroughs require selective or HMO licences. Check your council’s website. If you need a licence, apply online immediately for some issue within 5‑7 working days for a fee.
Day 3 – Deep clean and minor fixes
Hire a professional cleaner (£150–£300 for a 2‑bed flat). Fix dripping taps, broken handles, and any cracked paint. Neutral colours work best. Remove personal items and clutter. A fresh, neutral property photographs better and rents faster.
Day 4 – Professional photography and floor plan
Do not use your phone. Hire a local photographer who specialises in property. Cost: £120–£250 for 10–15 high‑resolution photos plus a floor plan. This single expense reduces vacancy by 3–5 days on average. Also shoot a simple video walkthrough. Tenants love them.
Day 5 – Set your “fast‑let” price
Research similar properties on Rightmove and Zoopla within a 0.5‑mile radius. Look at “let agreed” listings, not just current asking prices. Then apply one of two strategies:
| Strategy | Price vs Market | Expected Days to Let | Best For… |
| Fast-Let Price | 5–10% below market | 3–7 days | Properties with high vacancy costs or where an urgent let is required. |
| Optimum Price | At market rate or 2–3% above | 14–28 days | Landlords with lower urgency who want to maximise rental income and attract higher-quality tenants. |
Example: A flat worth £2,500/month. Fast‑let at £2,350. You “lose” £150/month but save 2 weeks of vacancy (£1,200). Over a 12‑month tenancy, you come out £1,050 ahead compared to waiting 3 weeks for £2,500.
Day 6 – Write a speed‑optimised listing
Lead with the strongest benefit: “Available immediately bright 2‑bed flat, 5 mins to Tube.” List key features: proximity to station, EPC rating, bills included or not, parking, garden, lift. Be honest but compelling. Include floor plan and video link.
Day 7 – Launch on multiple platforms simultaneously
List on Rightmove (through an agent or platform like OpenRent), Zoopla, and Facebook Marketplace. OpenRent’s “instant listing” goes live within hours. Pay for featured listings if your area is competitive they cut time‑to‑let by up to 40%.
Week 2 – Viewings, Offers & Signing
Day 8 – Pre‑screen every enquiry
Before you book a viewing, ask five questions:
- When do you need to move in? (Ideal answer: within 7 days)
- What is your combined household income? (Should be 2.5x annual rent)
- Do you have a guarantor if needed?
- Have you rented in London before?
- Can you provide a landlord reference today?
Only invite people who answer strongly. This cuts time‑wasters by 70%.
Day 9 – Block viewings
Schedule all viewings on the same day, back‑to‑back, within a 3‑hour window. This creates urgency for tenants see others interested. Offer evening or weekend slots. If you cannot manage viewings yourself, use an agency’s “viewings only” service (£100–£200).
Day 10 – Collect offers and decide fast
Do not wait for “better” offers. Set a deadline: “All offers by 5pm tomorrow.” Use a simple scorecard:
| Criteria | Weight | Score (1–5) | Notes |
| Move-in Date (earlier = higher score) | 30% | ||
| Income Stability | 25% | ||
| Previous Landlord Reference | 20% | ||
| Flexibility on Rent (e.g., paying 6 months upfront) | 15% | ||
| Gut Feel / Communication | 10% |
The highest scorer wins. Notify them within 2 hours.
Day 11 – Conduct Right to Rent checks
Use the Home Office’s free online service. Request original documents or share codes. Keep copies. Do not skip this, fines go up to £5,000 per tenant.
Day 12 – Prepare tenancy agreement and protect deposit
Use an Assured Shorthold Tenancy (AST) agreement templates from the NRLA or a solicitor. Include break clauses and your maintenance responsibilities.
Collect the deposit (typically 5 weeks’ rent) and protect it with a government scheme (DPS, TDS, or MyDeposits) within 30 days of receipt.
Day 13 – Sign digitally and hand over keys
Use DocuSign or a similar platform. Email the signed AST, safety certificates (gas, EICR, EPC), and deposit certificate to the tenant. Arrange key handover for the move‑in date.
Day 14 – Move‑in day
Walk through the property with the tenant. Complete a detailed inventory with dated photos. Both of you sign it. This prevents deposit disputes later.
Congratulations, you have rented out your house in London in 14 days.
Part 3: The “Speed vs. Yield” Trade‑Off | A Real Example
Let me show you two real scenarios from a 2‑bed flat in Zone 2 (average rent £2,500).
| Fast-Let Approach | Max-Yield Approach | |
| List Price | £2,350 | £2,600 |
| Days to Find Tenant | 6 | 28 |
| Lost Rent During Void | £500 (6 days) | £2,333 (28 days) |
| Total Annual Rent (12 Months) | £28,200 | £31,200 |
| Net After Void Loss | £27,700 | £28,867 |
The fast‑let landlord nets only £1,167 less over the year but has a tenant secured earlier, less stress, and a lease ending in a peak season (allowing another fast let). The max‑yield landlord endured nearly a month of zero income and higher risk of a problematic tenant.
For most London landlords, the fast‑let strategy wins.
Part 4: When to Use Guaranteed Rent or Fast‑Let Services
Sometimes you cannot wait 14 days. Maybe you are relocating abroad, or you need immediate cash flow. In that case, consider:
- Guaranteed rent schemes – Companies like Uncle, Goodlord, or some councils offer to pay you a fixed monthly rent (often 80‑90% of market) for 3‑5 years, regardless of vacancy. You get paid from day one. No void risk.
- Premium letting agents – Some agencies promise “tenant within 7 days or we reduce fees”. Read the small print they often achieve speed by pricing low. But if speed is everything, they work.

FAQ’s
Q1: Can I rent out my flat within a week?
Yes, but only if you have all legal documents ready (EPC, gas, EICR), price 10‑15% below market, and use priority listing services. Realistically, 7 days is tight 10‑14 days is more achievable for most.
Q2: Do I need an EPC before marketing?
Legally, yes. You cannot advertise a property without a valid EPC. However, you can order an express EPC (24‑48 hours) and start drafting your listing while you wait. Just do not publish without the certificate number.
Q3: What is the fastest way to get a gas safety certificate?
Use a Gas Safe registered engineer who offers “emergency” or “express” landlord certificates. Many charge £80–£120 for a same‑day or next‑day visit. Avoid companies that require a week’s notice.
Q4: How do I avoid time‑waster viewings?
Pre‑qualify every enquirer with the five questions above. Also, ask them to send proof of income (payslips or employment contract) before you confirm a viewing. Genuine tenants will not mind; time‑wasters will disappear.
Q5: Should I use OpenRent or a traditional agent for speed?
OpenRent lists on Rightmove and Zoopla within hours and charges a flat fee (£49‑£99). Traditional agents take days to process photos and write copy. For pure speed, use OpenRent or a similar DIY platform. For hands‑off speed, pay a premium agent.

Q6: What if the tenant passes reference checks but then delays moving in?
Write a “move‑in deadline” clause into your tenancy agreement: “Tenant must take possession within 7 days of signing, otherwise the landlord may cancel and retain the holding deposit.” This prevents endless delays.
Q7: Can I rent out my house while I still live in it?
Only as a lodger (you remain living there). For a full property rental, you must move out. If you need to rent a room quickly, lodger agreements are much simpler, no EPC or gas certificate required, but different rules apply.
Q8: How does seasonal timing affect speed?
Fastest months: January (post‑holiday moves), June–September (graduates and job starters). Slowest: December (holidays) and August (many people on holiday). If you can time your marketing to the end of August or early December, you cut void time by 30‑50%.
The One Mistake That Destroys Speed (And How to Avoid It)
The biggest killer of fast lets is waiting for the “perfect” tenant. Many landlords hold out for someone with perfect credit, a six‑figure salary, and a glowing reference. Meanwhile, three good enough tenants walk away because you took too long to decide.
A tenant with a minor credit blip from three years ago but stable employment and a genuine desire to stay long term is less risky than an empty property bleeding £100 a day. Chasing perfection often means rejecting applicants who would have paid rent on time, looked after the property, and renewed their lease all because you fixated on one small flaw.
Remember that references can be rehearsed, but a face‑to‑face conversation and a quick check of their current home’s condition (if possible) tells you more than any paperwork. The opportunity cost of waiting another week for a “better” candidate usually exceeds any hypothetical gain from a slightly higher rent or slightly stronger profile. Trust your screening process, but know when to pull the trigger – if an applicant meets your minimum criteria and you have no major red flags, say yes and move on.
Set a rule: “I will decide within 24 hours of the last viewing.” Use the scorecard above. A tenant with a stable job, decent references, and a reasonable move‑in date is better than an empty property for another month.
Final Verdict:
Renting out your house quickly in London is not luck. It is a repeatable system: legal checks, professional photos, smart pricing, fast viewings, and decisive tenant selection. Follow this blueprint, and you will cut vacancy from weeks to days.
