London Viewing Checklist 2026: Inspect These 10 Hidden Risks
A practical, up‑to‑date viewing checklist that helps London renters spot safety, legal and value risks when inspecting flats in February 2026. This guide covers ten must‑check items — from cladding/remediation status and EPC/MEES compliance to short‑let activity, landlord licensing, planned redevelopment, broadband/EV readiness and building insurance concerns — with step‑by‑step verification methods using current 2026 sources (RICS, Zoopla, Land Registry, London Datastore) and ready‑to‑use lines to ask at viewings and in follow‑up communications.
Why this checklist matters now
London’s rental market still reflects regulatory changes since the Building Safety Act 2022, ongoing energy‑efficiency enforcement under MEES, and rapidly shifting local policies on short‑lets and licensing. Small, hidden issues discovered at viewing can become big problems: higher service charges, long remediation delays, refusal of mortgage/insurance, or sudden loss of broadband or EV access.
Use this checklist at every viewing. For each item below you'll get a short explanation, how to verify (with specific 2026 sources and tools), practical examples, and ready‑made lines to ask the agent or landlord in person and by email.

1. Cladding, remediation and Building Safety status
Why it matters: Blocks built or reclad with higher‑risk materials can be subject to remediation, expensive major works and legal restrictions. Since 2022 the Building Safety Regulator and local building control have stricter reporting obligations for higher‑risk buildings (HRBs).
How to verify (step‑by‑step):
- Ask for the building’s current Building Safety Regulator (BSR) reference or the latest Fire Risk Assessment. Request dates and contact for the building safety manager.
- Check the BSR / government lists for HRBs and remediation programmes (search gov.uk for the Building Safety Regulator and current registers).
- Look for an EWS1-equivalent document or developer / managing‑agent statement about external wall remediation. RICS guidance on external wall safety (2024–2026 updates) is a useful reference when assessing professional reports.
- Check recent Land Registry title entries for any charges or notices that reference remediation obligations.
Practical example: If the agent says “no cladding issues,” ask for a dated written statement. Many landlords confuse cosmetic cladding with ACM cladding — get the material and specification in writing.
What to ask at the viewing:
- “Is this block registered as a higher‑risk building with the Building Safety Regulator? Can you provide the current certificate or reference?”
- “Has any external wall remediation been carried out or instructed? Please email the remediation/major works notice and the last service charge statement.”
Follow‑up email line (copy/paste):
"Please can you forward any building safety manager contact, the latest fire risk assessment, and any notices or invoices relating to external wall remediation or major works on this block? I need these for my decision to proceed."
2. EPC & MEES compliance (energy‑efficiency)
Why it matters: Since MEES rules require privately rented properties in England to have a minimum EPC rating (usually an E) or a valid exemption, renting a property without proof is a legal risk. EPCs also show ventilation issues, insulation and predicted running costs.
How to verify:
- Ask for the full EPC certificate and the date it was issued. The certificate should include recommended improvements and an assessor’s contact.
- Cross‑check the EPC on the national EPC Register (gov.uk EPC register) by address — the register is the authoritative public record.
- Use Zoopla or local comparables to confirm whether the listed rent is reasonable given the EPC rating. Poor EPC + high rent is a negotiating point.
Practical example: A flat with an EPC D but large gas bills in winter might reveal poor insulation or failing loft cavity wall insulation. EPC recommendations often point to specific fixes you can request before moving in.
What to ask at the viewing:
- “Can I see the EPC certificate and the date it was done? Have any recommendations been actioned?”
Follow‑up email line:
"Please attach the EPC certificate and any invoices for energy‑efficiency work completed in the last 5 years (loft insulation, double glazing, boiler replacement)."
3. Landlord licensing & HMO rules
Why it matters: Many London boroughs require selective licensing or additional HMO licensing (for houses/large flats with multiple occupancies). A landlord must hold the right licences or risk fines; tenants can be affected by changing conditions or enforcement action.
How to verify:
- Identify the local authority where the property sits and check their selective/HMO licensing pages (London borough websites). London Datastore includes borough boundaries and can help confirm which borough the address is in.
- Ask the agent/landlord for the licence number and expiry date. Verify the number on the council’s licensing search page where available.
- If you plan to houseshare, check HMO rules and maximum occupancy.
Practical example: A landlord lists a three‑bed flat as “suitable for sharers” but does not hold an HMO licence — council enforcement can lead to fines and possible disruption.
What to ask at the viewing:
- “Does this property fall under your borough’s selective or HMO licensing scheme? Can you provide the licence number?”
Follow‑up email line:
"Please send the selective/HMO licence details (licence number, issuing authority, expiry). I will verify these with the council before signing."
4. Short‑let / Airbnb activity (neighbourhood & risk)
Why it matters: Properties used for short‑lets can mean transient neighbours, greater wear and tear, and in some boroughs legal limits or licensing. Persistent short‑let activity can also affect insurance and building management’s view of you.
How to verify:
- Search the address and building on popular short‑let platforms (Airbnb, Vrbo) and use Inside Airbnb or AirDNA to see frequency and listing history.
- Check the borough’s short‑let or planning policies — many now require registration or planning permission for regular short‑lets.
- Ask the agent if the landlord permits subletting or short‑letting and whether past tenants have used the property for that purpose.
Practical example: A flat advertised as a “great investment” may actually be part of a managed short‑let portfolio that runs many guests per month — this changes living conditions.
What to ask at the viewing:
- “Has this flat been used for short‑term holiday lets in the past 12 months? If so, can you share the management details or example listings?”
Follow‑up email line:
"Please confirm whether the landlord permits subletting or short‑term letting and provide any management/hosting records for the last 12 months."
5. Building insurance, service charges & major works
Why it matters: High or rising building insurance and upcoming major works can push service charges up or be passed to leaseholders — and if the landlord has limited funds, they may struggle to cover costs that affect the building.
How to verify:
- Ask for the most recent service charge account and the insurance schedule for the block. The schedule should show insurer, policy period, and sum insured.
- Check the last 2–3 years of service charge invoices for major works notices. Ask whether any major works have been agreed and how costs will be allocated.
- Use the Land Registry to check whether the freeholder has any charges registered against the title that might indicate developer or lender involvement.
Practical example: A leasehold block that had a large remediation project often shows a recent spike in service charges and a major‑works repayment schedule.
What to ask at the viewing:
- “Who insures the building, can I see the policy summary, and are there any planned major works in the next 24 months?”
Follow‑up email line:
"Please provide copies of the last two service charge statements, the building insurance schedule, and any notices relating to major works or anticipated service charge increases."
6. Fire safety, alarms & higher‑risk building (HRB) checks
Why it matters: Fire safety is non‑negotiable. For higher‑risk buildings (usually high rise), there are extra duties on the accountable person and building safety case reports to show compliance.
How to verify:
- Request the most recent Fire Risk Assessment and ask whether alarms are interlinked and when they were last tested.
- For buildings over the HRB threshold, request the building safety manager’s contact and the building safety case reference (BSR).
- Check for visible safety features at the viewing: clear escape routes, signage, functioning emergency lighting, and inspected communal doors.
Practical example: A small two‑bed on the 12th floor should have a clear evacuation plan and documented tests; if the agent cannot provide these, treat it as a red flag.
What to ask at the viewing:
- “Can you show me the last fire alarm and emergency lighting service dates and the latest fire risk assessment?”
Follow‑up email line:
"Please forward the latest fire risk assessment and a confirmation that the smoke/heat detectors and communal emergency lighting were tested in the last 12 months."
7. Planning applications & redevelopment risk
Why it matters: Nearby redevelopment or planning approvals can mean months of noisy building works, changes to outlook, or eventual loss of amenities. Significant schemes can also push up values and rents — or reduce them if they bring unwanted uses.
How to verify:
- Search the local authority planning portal for the address and neighbouring sites (use the council planning search tool). London Datastore contains planning datasets and boundary maps you can use for context.
- Look at Land Registry for recent land transactions nearby — big purchases often precede redevelopment.
- Check Zoopla/property portals for “under offer” notes or agent comments signalling developer interest.
Practical example: An empty site adjacent to the block with a recent outline application for flats or student accommodation is a sign of upcoming disruption.
What to ask at the viewing:
- “Are there any current planning applications affecting this building or neighbouring sites?”
Follow‑up email line:
"Please confirm whether any planning applications affecting the immediate vicinity are known to the managing agent and send links to any existing council planning notices."
8. Broadband & digital connectivity (Openreach / Ofcom checks)
Why it matters: Working from home, streaming and reliable digital access are essential. Not all central London blocks have full fibre or high‑speed options in every flat.
How to verify:
- Use Openreach’s availability checker (or the provider’s postcode checker) to confirm fibre‑to‑the-premises or fibre‑to‑the-cabinet availability for the exact address.
- Check Ofcom’s broadband checker for real‑world speeds in the postcode.
- Ask the landlord which provider previous tenants used and whether any internal wiring or communal fibre has been installed.
Practical example: A top‑floor flat listed as “good for remote work” but with confirmed ADSL speeds at the address is a mismatch — a wired Ethernet or dedicated FTTP upgrade may be needed.
What to ask at the viewing:
- “Which ISPs serve this address and what speed package have previous tenants used?”
Follow‑up email line:
"Please confirm the broadband provider used at the property and whether any internal wiring (Ethernet ports) or FTTP infrastructure is present."
9. EV charging & sustainability readiness
Why it matters: If you own or expect an electric vehicle, communal charging and local council policies matter. The London environment agenda and borough EV strategies can affect future parking and charge‑point installations.
How to verify:
- Check Zap‑Map and local council maps for public charge points near the building. London Datastore publishes datasets for public EV charge points by borough.
- Ask the managing agent whether the building has conduit for retrospective charge‑point installation or a policy for landlord‑installed chargers.
- If parking is on‑site, ask whether EV charging is allowed and if there’s a plan or cost estimate for installing sockets.
Practical example: A leaseholder block may need communal decisions (and a major‑works vote) to install charge points — which takes time and money.
What to ask at the viewing:
- “Is there a communal EV charging plan or any installed charge points? If not, is permission likely for a tenant or leaseholder to install one?”
Follow‑up email line:
"Please provide details of current EV charge points serving the building and any plan or estimate for adding more."
10. Damp, ventilation, and tenancy clauses to watch
Why it matters: Damp and poor ventilation are health hazards and common grounds for disputes. Meanwhile, tenancy clauses (break clauses, rent review, permission to decorate, subletting) can lock you into unfavourable terms.
How to verify:
- Inspect for visible signs of damp, peeling paint, musty odours, and functioning extractor fans. Ask when windows and extractors were last serviced.
- Request any tenancy draft to read key clauses, and check the tenant set‑up for deposit protection and prescribed information (see Understanding Tenancy Agreements: What to Look For).
- If the landlord asks for unusual clauses (e.g., no guests, strict cleaning fines), consider negotiating these out or asking for them in writing as permitted exceptions.
Practical example: An agent says tenants must use a specific cleaning contractor for move‑out cleaning — get the contract, fees and an opt‑out option in writing.
What to ask at the viewing:
- “Have you experienced damp or recurring condensation issues in this flat? Are extract fans ducted externally?”
Follow‑up email line:
"Please send a draft of the proposed tenancy agreement and the last property inventory, plus dates of the last landlord/agent inspections and any damp mitigation works completed."
How to use these checks at a viewing (practical workflow)
- Print the Quick checklist and bring a phone for live checks (EPC register, Openreach, Airbnb search).
- Ask the three prioritised questions first: cladding/building safety, EPC/energy rating, and planned major works/service charges. If answers are satisfactory, proceed through the remaining checks.
- Take photos of communal areas (front doors, lifts, corridors, bin stores) and note alarm/test dates on notices.
- When you leave, send a short follow‑up email asking for the specific documents you were promised — this creates a written record.
Sample follow‑up email (copy/paste):
"Thanks for showing me the flat at [ADDRESS] today. As discussed, please can you send the following so I can progress my decision: EPC certificate, latest fire risk assessment, building insurance schedule, last two service charge statements, any remediation/major works notices and confirmation of landlord licensing. Thanks — [YOUR NAME]."
Negotiation tips when you find an issue
- Use a dated deficiency (e.g., lack of EPC or known remediation) to ask for a rent reduction, an initial repair completion, or a capped agreement on service charge increases. Cite the evidence (EPC register entry, council notices) when you negotiate.
- If broadband/fibre is absent but critical to you, ask the landlord to allow and fund a fibre install or offer a rent reduction until speeds are improved.
- For short‑let concerns, ask for a clause in the tenancy prohibiting landlord‑authorised short‑let activity during your tenancy.

Final notes — protect yourself with paperwork
A verbal assurance at a viewing is not enough. Always get key safety, licensing and financial documents in writing before you sign. Use the sample lines in this article for a clear, professional approach. If something significant is missing (no EPC, no fire assessment, no licence where required), pause the process — repair or clarification can take weeks.
