You can find out roughly how old your wiring is by simply looking at it. If the wiring around your fuse box is covered in old-fashioned casing, or is damaged or fraid, it may be over 25 years old and need replacing. This is more common in older properties or houses that have been empty for long periods of time.
Marlborough
Marlborough is a market town and also civil church in the English region of Wiltshire on the Old Bath Road, the old highway from London to Bath. It boasts the second best high road in Britain, after Stockton-on-Tees. The town is on the River Kennet, 24 miles (39 km) north of Salisbury and 10 miles (16 kilometres) south-southeast of Swindon. Marlborough has a nautical environment somewhat influenced by its inland placement as well as at 124 metres' elevation is much more vulnerable to frost than southern coastal areas. In 2004 Marlborough celebrated 800 years of its Town Charter. Among the parties were a street play by the Marlborough Players labelled Wheels of Time, and also a browse through from HRH Prince Charles.
