Quick response and clear communication from start to finish. Booked the callback at 8am, had an engineer that afternoon.

Easy to explain the issue and get a callback. Honest, no upsell — boiler running the same day.
DO

Notting Hill · W11
Professional, helpful and straightforward. Used them twice — once for a leak, once for a new bathroom tap. Both sorted properly.

Called them for an emergency leak under the kitchen sink. Sorted it the same day and left everything spotless. Couldn't fault them.
