BTL Conveyancing 2026

Conveyancing for Buy-to-Let — Searches, Title Investigation, HMO Licence Checks, SDLT Surcharge and Land Registry

Conveyancing for buy-to-let purchase 2026: the BTL conveyancing process differs from residential purchase — HMO licence checks essential (HMO licences NOT transferable on sale; buyer must apply for a new licence); SDLT 3% additional dwelling surcharge applies; CML Handbook compliance for BTL mortgage lender. Key stages: (1) Searches: Local Authority (planning; enforcement; article 4 directions — critical for intended HMO use); water and drainage (CON29DW); environmental (contamination; flooding; ground stability); chancel repair liability; coal mining (where applicable). (2) Title investigation: Official Copies (OC1/OC2); existing charges (mortgages to discharge); restrictive covenants; easements; leasehold (lease term; ground rent; service charge history; section 20 notices); HMO licence enquiries. (3) Pre-contract enquiries (TA6/TA10): boundaries; tenancies; deposits; outstanding enforcement. (4) Exchange: 10% deposit; completion date. (5) Completion: balance transferred; keys released; buyer becomes legal owner. (6) SDLT (England): 14-day deadline; 3% surcharge for additional dwellings. LBTT + ADS 6% (Scotland; 30 days). LTT higher residential rates (Wales; 30 days). (7) Land Registry: TR1 transfer + CH1 charge; 1-6 months to register; title absolute.

Searches, title investigation and HMO licence checks

The buyer's solicitor orders searches and investigates title before exchange of contracts — the BTL-specific issues to focus on:

  • Local Authority Search (LLC1 + CON29): reveals planning permissions and refusals; enforcement notices; listed building status and conservation area; article 4 directions (critical for BTL buyers intending HMO use — an Article 4 direction removes permitted development rights for HMO conversion; the local authority search will reveal any Article 4 direction in force); road adoption; public rights of way; drainage agreements; compulsory purchase
  • Water and Drainage Search (CON29DW): confirms connection to public water supply and sewer; records of adopted drains and sewers; flooding from water company data
  • Environmental Search: risk of contaminated land (former industrial use; landfill; petrol stations); flooding (EA Flood Zone maps; surface water; rivers and sea); ground stability and subsidence; radon gas levels
  • Chancel Repair Liability Search: whether the property lies within a historic ecclesiastical parish where chancel repair liability attaches to freeholders — since 2013 this must be registered to be enforceable but unregistered historic liabilities may remain relevant
  • Coal Mining Search (where applicable): essential in former coal mining areas (South Wales; Yorkshire; Nottinghamshire; County Durham; Tyne and Wear) — reveals subsidence risk from former workings
  • Title investigation — Official Copies (OC1 and OC2): (a) Existing charges (mortgages): the seller's mortgage must be discharged on completion; buyer's solicitor obtains redemption statement and ensures Form DS1/DS3 discharge is registered; (b) Restrictive covenants: historic restrictions on use or development (no commercial use; no subdivision; no extension without consent) — critical for HMO conversions and planned alterations; (c) Easements and rights: rights of way; drainage rights; shared access; party wall arrangements; (d) Leasehold: lease term remaining; ground rent (must be peppercorn for new leases under Leasehold Reform (Ground Rent) Act 2022); service charge history (check for large planned or historic major works); section 20 consultation compliance; (e) HMO licence checks: if the property is currently let or intended to be let as a mandatory HMO, raise pre-contract enquiries about the existing HMO licence (number; expiry date; conditions; any outstanding enforcement); HMO licences are NOT transferable on sale in England — the buyer must apply for a new mandatory HMO licence from the local authority before letting the property as an HMO; applications can be submitted in advance of completion

Exchange, completion, SDLT/LBTT/LTT and Land Registry registration

  • Pre-contract enquiries (TA6/TA10 for residential; CPSE for commercial): boundaries; disputes; notices; planning and building regulations; utilities; current tenancies; deposit protection details (these obligations transfer to the buyer on completion — ensure deposits are in a scheme and prescribed information has been served); outstanding notices or possession proceedings
  • Exchange of contracts: the legally binding commitment; buyer pays 10% deposit (by arrangement, sometimes 5%); completion date agreed (typically 4-8 weeks after exchange for standard residential BTL); in a chain, exchange is coordinated across all parties
  • Completion: balance of purchase price transferred electronically; keys released; buyer becomes legal owner and steps into the landlord's shoes for existing tenancy obligations
  • SDLT (England) — due within 14 days of completion: BTL purchases (second or additional residential property) attract the 3% additional dwelling surcharge in addition to standard SDLT rates; the surcharge applies to the full purchase price; SDLT return must be filed and SDLT paid within 14 days of completion — HMRC imposes automatic penalties and interest for late filing; most solicitors file SDLT as part of completion but the buyer should confirm this
  • LBTT + ADS (Scotland): Land and Buildings Transaction Tax at standard residential rates; Additional Dwelling Supplement (ADS) at 6% (from April 2024) applies to BTL purchases; return filed and tax paid within 30 days of completion (the effective date of transaction)
  • LTT (Wales): Land Transaction Tax at Higher Residential Rates applies to additional residential property purchases in Wales; return filed and tax paid within 30 days of completion
  • Land Registry registration: after completion, the buyer's solicitor applies to register the transfer (Form TR1) and any new mortgage charge (Form CH1); standard applications typically registered within 1-6 months; leasehold registration may take longer; the buyer receives an Official Copy of the updated title register; title registered as Title Absolute (freehold and good leasehold) or Qualified/Possessory (defective titles)

Frequently asked questions

Can I take over the existing HMO licence when I buy a property?+

No — HMO licences in England are not transferable on sale. When you purchase a property that is or will be operated as a mandatory licensable HMO, you must apply for a new mandatory HMO licence from the local authority before letting the property as an HMO. Applications can often be submitted before completion (in anticipation of purchase) to minimise any gap. Operating an HMO without a licence carries a civil penalty of up to £30,000 and tenants can apply for Rent Repayment Orders.

How long do I have to pay SDLT after buying a buy-to-let property?+

In England, SDLT must be paid and the SDLT return filed within 14 days of completion — not 30 days. Missing the 14-day deadline triggers automatic HMRC interest and surcharges. For BTL purchases (an additional residential property), the 3% additional dwelling surcharge applies to the full purchase price on top of the standard SDLT residential rates. In Scotland (LBTT + ADS) and Wales (LTT), the deadline is 30 days.

What searches do I need when buying a buy-to-let property?+

The standard searches are: Local Authority search (planning; enforcement; article 4 directions — critical for intended HMO use; road adoption); water and drainage search (sewers; water connection); environmental search (contamination; flooding; ground stability); chancel repair liability search; and coal mining search (in former mining areas). The local authority search is particularly important for BTL buyers: it reveals any Article 4 directions restricting HMO conversion, planning enforcement notices, and conservation area or listed building status.

What happens to the existing tenants when I buy a tenanted buy-to-let property?+

If you purchase a property with tenants in situ, you step into the landlord's shoes on completion and inherit all existing tenancy obligations: the existing tenancy agreements continue unchanged; you must protect any deposits in an approved scheme (if not already done, liability falls on you from completion); you must serve a change of landlord notice under LTA 1985 s.3. You cannot immediately evict tenants simply because you have purchased the property.

Portfolio Landlord Mortgage UK 2026 — PRA SS13/16 Rules, 4-Property Definition, ICR Stress Test, Portfolio Questionnaire, Specialist Lenders and Top-Slicing
Portfolio landlord mortgage UK 2026: PRA Supervisory Statement SS13/16 (effective 30 September 2017) introduced specialist underwriting requirements for portfolio landlords — defined as landlords with 4 or more mortgaged BTL properties across ALL lenders (not per lender; properties owned outright do not count). Portfolio questionnaire required: all mortgaged properties (address; value; balance; rent; rate; lender; expiry); aggregate portfolio LTV; aggregate ICR; void periods; business plan. ICR stress test: individual property minimum 125% rental coverage at stressed rate (typically 5.5%); 145% for higher-rate taxpayers (Section 24 impact). Aggregate portfolio ICR also required across all mortgaged BTL properties. Background portfolio assessment: even on a single BTL remortgage, the whole portfolio must be assessed. Specialist lenders dominate post-SS13/16 (Paragon; The Mortgage Works; Kent Reliance; Fleet Mortgages; Foundation Home Loans; Accord). Top-slicing: personal income can supplement ICR where rental income alone does not meet the 125% threshold at stressed rates.
