If your home security plan is basically “lock up and hope for the best”, you are not alone. The good news is that most security improvements are simple, affordable and additive; you can tighten weak points without turning your house into a fortress.
Below is a practical checklist we use when advising homeowners across Hertfordshire, Bedfordshire and Buckinghamshire. Work through it once a year and after any big change, such as moving in, renovating or replacing doors and windows.
1) Start with the perimeter
Walk around your property in daylight, then again at night. Ask two questions: where can someone get close to the house unseen, and where could they linger without being noticed? Pay particular attention to side access, rear gardens, alleys, bins and sheds.
Quick wins:
- Trim back shrubs that provide cover near doors and windows.
- Move ladders and tools out of reach or lock them away.
- Add a gate or improve side access locks if the path to the rear is open.
2) Check doors: locks, frames and habits
Front and back doors are still the main targets. A strong lock on a weak frame is not enough, so check both.
Checklist:
- Multi point locks on uPVC or composite doors should engage fully; lift the handle to lock properly.
- Wooden doors should have a good quality mortice deadlock and a robust strike plate.
- Look for movement in hinges, loose screws, and any gaps around the frame.
- Fit a door viewer or video doorbell if you regularly take deliveries.
3) Windows: secure the easy routes
Ground floor windows, and upper windows above flat roofs or extensions, are common entry points.
Checklist:
- Ensure window locks are present and used, especially on accessible windows.
- Consider laminated glass or security film for vulnerable panes.
- Do not leave keys in the lock where they can be reached through a letterbox or broken glass.
4) Lighting: deterrence that costs very little
Good lighting changes behaviour. The goal is not to flood the whole garden, but to remove dark approaches and blind spots.
Checklist:
- Use PIR lights on side access, driveway and rear doors.
- Avoid aiming lights directly at cameras; glare reduces footage quality.
- Consider low level lighting along paths to reduce trip hazards.
5) Alarm systems: detection and response
A modern intruder alarm gives you early warning and, importantly, encourages most opportunists to leave quickly.
Checklist:
- Decide whether you want a bells only system or app notifications.
- Cover likely routes: entry doors, hallways, stairs, and rooms with valuables.
- Include a smoke detector or heat detector if you want extra safety integration, but keep fire systems to the right standard.
6) CCTV: evidence and reassurance
CCTV is most effective when it supports a clear purpose: deterrence, identifying visitors, or capturing evidence after an incident.
Checklist:
- Cover the driveway, front door, side path and rear access.
- Make sure night performance is good enough to capture faces, not just shapes.
- Set recording and motion zones carefully to reduce false alerts.
7) Small details that make a big difference
- Use visible house numbers for emergency access.
- Keep your front door clear of packaging that signals high value deliveries.
- Use timers for lights when you are away.
- Store car keys out of sight, ideally in a Faraday pouch if you have keyless entry.
8) When to get a professional survey
If you have multiple access points, a large plot, or recurring nuisance issues, a short site survey can save money. You can prioritise the right upgrades, avoid unnecessary gadgets, and ensure your system is installed neatly and reliably.
