Quick answer

The landlord cannot absolutely prohibit drilling into walls. Light fixings (plugs, hooks, shelves, picture hangings) are part of normal enjoyment of the property. Major drilling (load-bearing walls, pipe penetrations) requires the landlord’s written consent. The tenant must fill all holes when leaving.

Any lease clause that absolutely prohibits drilling is considered abusive and may be voided by a judge. The tenant has a right to personalise the living space within reasonable limits.

ActionConsent needed?
Hanging pictures with plugsNo
Installing shelves (standard plugs)No
Mounting a TV bracketNo (standard plugs)
Hanging curtain rodsNo
Drilling into load-bearing wallsYes
Penetrating walls for pipes/cablesYes
Installing heavy items (climbing wall, etc.)Yes
Fill holes on departure

All holes must be properly filled (filler, sanded, and optionally painted) before the exit inventory. Unfilled holes may lead to deductions from the deposit. Standard plug holes (6-8mm) are easy to fill and should not cause issues.

End of lease obligations

At the exit inventory:

  • Small plug holes (properly filled): should not result in deductions
  • Unfilled holes: the landlord can deduct the cost of repair
  • Damage to load-bearing walls (without consent): the tenant bears full repair costs
  • Excessive holes: even if filled, an unreasonable number of holes may be considered damage

The entry inventory serves as the comparison reference. Holes that existed at entry cannot be charged to the tenant at exit.
