Protecting Your Home While it’s up for Sale

Selling your home brings more visitors and temporary access, which can quietly increase risk – here’s how to secure valuables manage key safes update alarms and keep your property protected throughout the sales process.

House for sale security

Putting your home on the market is an exciting step, but it can also mean more people coming and going than usual. Estate agents, photographers, surveyors, trades and prospective buyers may all need access over a short period of time.

While viewings are usually well managed, the sales process can unintentionally loosen your usual security habits. Doors are opened, routines change, and unfamiliar visitors walk through your space.

Here’s how to protect your home while it’s up for sale, without disrupting the process or putting off potential buyers.

More footfall, more risk

When your property is listed, footfall increases almost overnight. Open viewings, back-to-back appointments and last-minute access requests can make it harder to maintain your normal security checks.

During viewings, doors and windows may be opened for light or ventilation and not fully secured afterwards.

In flats, communal entrances may be propped open. Viewers can also gain insight into your layout, spotting side access, alarm panels or where valuables are usually kept.

Practical steps:

  • Ensure viewings are always supervised by an agent or responsible adult.
  • Carry out a full lock check after every appointment.
  • Restrict access to non-essential rooms where possible.
  • Avoid discussing holiday plans or routines in front of viewers – even to the point of concealing calendars with holiday dates on.

A few simple habits can significantly reduce risk while your property is on the market.

Key safes, codes and contractor access

During the sales process, convenience often takes priority. Temporary key safes may be installed to allow estate agents access, and alarm codes or smart lock credentials may be shared with photographers, cleaners or contractors preparing the property for marketing.

The difficulty comes when that temporary access becomes unclear or unaccounted for. Codes are reused, not updated, or remain active long after they’re needed. And if a key has been copied during the process, you may never know.

Practical steps:

  • Choose a high-quality, police-approved key safe rather than a basic budget model.
  • Change alarm or lock codes regularly throughout the sales period.
  • Remove the key safe as soon as the sale completes.
  • If you’re unsure who may have access, consider rekeying or upgrading your locks for complete peace of mind.
  • Consider installing smart locks that allow you to issue and easily cancel temporary access via a smartphone.

Selling your home should feel controlled — not uncertain.

Protecting valuables and personal data

Viewings don’t just expose your living space — they can also reveal what you own.

Jewellery, laptops, tablets and small electronics are easy to overlook when staging a home, especially if they’re part of everyday life.

Paperwork can be just as valuable. Bank statements, utility bills and ID documents left on desks or kitchen counters can provide personal information that criminals misuse long after a viewing has ended. Even spare keys tucked into “safe” but predictable hiding spots can be discovered by someone paying close attention.

Practical steps:

  • Remove or securely store small valuables during open viewings.
  • Lock away sensitive documents rather than leaving them in visible drawers.
  • Use a home safe for jewellery, passports and important paperwork.
  • Avoid posting on social media about viewings, holidays or times the house will be empty.
  • If you work from home, clear your desk of any work-related documentation or commercially sensitive information.

A tidy home is appealing to buyers — but a secure home protects you long after they leave.

Temporary security enhancements during the sales period

If your home is attracting regular visitors, it may be worth strengthening security temporarily while it’s on the market. A professionally monitored alarm system ensures that any activation is responded to quickly — even if you’re not at home.

Temporary CCTV or smart doorbell cameras can also provide reassurance. Not only do they record activity at entry points, but their visible presence acts as a deterrent.

Well-positioned dusk-to-dawn security lighting around entrances, driveways and side access points further reduces the opportunity for unwanted attention after dark.

Practical steps:

  • Consider short-term monitoring options during the sales period.
  • Ensure cameras and intruder alarms are properly integrated rather than operating as standalone devices.
  • Check that security lighting positioning covers new or less visible access points.

The goal isn’t to turn your home into a fortress — it’s to show that it’s well protected while viewings are underway.
