There are several ways to mark your property depending on the type of object you want to mark. The alternatives are:

• Ultra violet or 'invisible' marking

An ultra-violet pen (UV)can put an invisible mark on your property which can only be seen using a UV lamp. Only use UV marking when other marking methods would reduce the value of the object. Remember that the mark can fade in time, especially when exposed to sunlight, and can be washed off so it needs renewing regularly.

• Engraving or etching

Engraving or etching is suitable for many hard surfaces and can be done using an electric engraving tool or a hand engraver. This method leaves a visible and permanent mark.

• Ceramic marking

Ceramic marking pens have been developed to mark china, glass and any glazed surface. They do not cut or scratch the surface but leave a permanent mark.

• Punching

You can mark heavier metal items such as lawn mowers with a hammer and a set of punches.

Where do I mark my property?

Where you mark your property is important - particularly if you are using the engraving method. If you want the mark to be out of sight, choose somewhere behind or underneath the article - but not somewhere so hidden that the police would not be able to find it!

If you use commercial property marking products the mark should be so secure that removal would deface the property or affect the performance of the article. Always include information which will identify the owner - for example; the postcode.

You can get easy-to-use property marking kits from stationers and DIY stores.

How to mark your property

• Use a security marker pen with your postcode followed by the house number or the first two letters of the house name eg AN1 2ZG 12, AN1 2ZG RO
• Use a marker pen on parts of the property which are not cleaned
• Use a pen if possible on parts not too easily visible
• Do not use a pen on paintings(frames are all right), fabric or paper
• For modern garden furniture paint on your post code where it is not too easily visible
• Consider using commercial products for marking eg microdots and etching (for metal items)
