Do I Need a Plumber for Kitchen Installation?

Yes — you will need a qualified plumber for first and second-fix plumbing (water supply and waste connections). Due to high demand, we recommend arranging your own qualified plumbers, electricians and gas engineers before your installation date wherever possible.

Key Takeaways
  • A qualified plumber is needed for water supply and waste connections
  • First fix (pipe positions) must be done before installation
  • Second fix (connecting sink/dishwasher) happens after units are in
  • Arrange your plumber before booking your installation date

Plumbing and Kitchen Installation

Kitchen installation involves two distinct plumbing stages — first fix and second fix — and both require a qualified plumber. Understanding the difference helps you plan your project effectively.

First Fix Plumbing

First fix plumbing covers all the pipework that needs to be in place before kitchen installation begins. This includes routing the cold water supply to the sink position, routing the waste pipe to the sink and dishwasher positions, and capping or re-routing any existing pipes that no longer align with the new layout. First fix must be complete — with pipes in their final positions — before we begin installing units.

Second Fix Plumbing

Second fix plumbing connects the appliances and sink once the units and worktop are in place. This includes connecting the tap to the water supply, connecting the waste to the sink bowl and dishwasher, and connecting any plumbed appliances such as a washing machine or fridge with water dispenser. Second fix typically takes half a day and is scheduled towards the end of the kitchen installation programme, after the worktop is fitted.

Electrical and Gas

In addition to plumbing, most kitchens require an electrician for second fix electrical work — connecting hardwired appliances such as ovens and hobs, fitting sockets, and testing circuits. If your kitchen includes a gas hob or range cooker, a Gas Safe registered engineer is required. Due to high demand and fast-filling slots, we recommend arranging all of these tradespeople well in advance of your installation date.

Our installation service does not include plumbing. We work alongside your plumber to co-ordinate the first and second fix stages within the installation programme.

Book your plumber as early as possible — ideally at the same time you book your installation date. Good plumbers are in high demand. Your installation survey will confirm the exact programme so you can schedule trades accordingly.

No — Gas Safe registration is only required for gas appliances (hobs, range cookers, gas ovens). An electric hob requires an electrician for a hardwired connection.

If first fix is not complete when we are scheduled to start, we may not be able to begin installation. We will work with you to reschedule as early as possible, but delays to trades are a leading cause of installation delays. The survey helps you plan all trades accurately.
