It is advisable to now how to turn off your main stopcock before you ahve a leak.
In most houses it will be located under the sink or in a cupboard on the outside  wall of your house . If it is difficult to find then it could be in a downstairs bathroom or toilet.  It may be that the stopcock is impossible to turn off or very stiff.. In this situation it is worth knowing how to turn off your mains supply from outside your home. There will be an access plate on the perimeter of your house, usually on the pavement outside your main entrance  or in your driveway. Newer properties will have a simple 1/4 turn gate valve at the bottom of the acces hole to the stopcock. In older houses that haven't been converted to the newer valves, you may need a special long reach tool to tun of the water. Check it out before there is a problem

The overflow pipe that you can see on the side of your house will come from the cold water tank or your expansion tank  for the central heating system. If the is a steady drip this will almost certainly be caused by a leaking seal of the ball valve controling the coldwater feed to your tank.. Usually it is advisable to change over the complete ball valve assembly ( under £10) rather than replace the seal, unless the valve looke new. This will also replace any other parts that may be wearing.. I recently was called to a house where there was a steady flow from the overlow. On investigation this was caused by the ball float detaching from the valve arm. In this case the "brass" arm had sheared/corroded at the screw thread that held the float..

Tall or out of place trees need occassional pruning. I use a Stihl pole pruner that can reach 12 ft and prune branches of 6 inches diameter. This is far better and safer than climbing the tree.

It  is recommended that all houses be fitted with sufficient  smoke alarms.  Any house with gas appliances should also have  carbon monoxide alarms    fitted for safety these alarms are relatively easy to fit although the recommended positions sometimes   high on a wall  or ceiling  means that handyman may need to be called in

 sheds and greenhouses need to be sited on firm footings.  these are usually concrete or brick foundations.  Sometimes greenhouses are supplied with the a metal frame base that serves the job of foundations.   it is important  that the foundations are level as any irregularities will   deform the  shape of the  shed all greenhouse.

Most low hedges can be a DIY job. However, High hedges can be dangerous to cut. A professional Gardener may have a long-reach hedge cutter. I use a Stihl extendable  cutter that can reach the top of 10 ft hedges from the ground. The  main problem is then disposal ofd the cuttings. Ask your gardener for a price to cut the hedge and then a price for disposal. You could save yourself a bit if you do the removal yourselves

Dripping taps are easy to fix. There are a number of seals and washers in the tap body that are designed to keep the water inside. The tap washer is usually the main cause of all leaks from the tap causing the dripping tap problem. Unfortuantey there are dozens of different washers designed for different taps. Most good Pumbers will have a selection of these washers, which will mean that they don't have to "go out" for a part and charge you the time.
