Drain pipe needs repairing as water entering in my kitchen

Could be a number of things here 1 the waste pipes that go through the wall to the drain may be damaged and water could be leaking in through the cavity 2 the gully on the outside may be higher than the floor level inside the house and if the fall of the ground is towards the house gully could be blocked 3 your water supply could be damaged and leaking under the floor we alway give free quotes but I would need do a site visit to investigate this further thanks

Any builder should be able to deal with this. The only problem might be if the water is coming in from the mains pipe before the water meter if you have one. Technically that should be done by the water board. This is the case so that no one can take water before the meter, avoiding the cost of the water that you are using but not being metered for. (Assuming that you have a meter. If not, then this bit is irrelevant.)
