Built-in Oven Installation Guide

Scope of Works

• Carry out pre-site survey: confirm aperture size, circuit rating (kW vs MCB), isolation switch, and removal route.

• Isolate electricity; disconnect and lift out old oven, cap or re-terminate cable tails.

• Inspect existing 6 mm²/32 A or 13 A supply and upgrade cabling or breaker if the new appliance demands it.

• Slide new oven into cabinet, align and fix through factory-drilled side brackets; re-fit trim/pelmet.

• Make electrical connection (hard-wire or plug) and earth-bond metal housing; fit cooker-control faceplate.

• Level appliance, reinstate door furniture, test functions, run burn-off cycle, and register warranty.

• Remove packaging and, if agreed, take away the old oven for WEEE-compliant recycling.

  
  

Typical Cost (inc. VAT)

Time on Site

1 – 3 hours for a straight electrical replacement.Longer if: cabinetry needs trimming, new 6 mm² cable/RCBO is required, or the old oven is gas-fuelled and must be capped and certified.

Questions to Ask Your Tradie

1. Are you Part P registered (or Gas Safe, if capping gas) and will you issue the relevant certificate?

2. Is removal and WEEE recycling of the old oven included in the quote?

3. Will the existing circuit and isolation switch meet the new oven’s kW rating, or will cabling/breakers be upgraded?

4. Do you supply new mounting screws, trims and a metal cooker-control plate?

5. How will you protect floors, work-tops and adjacent cabinets during installation?

6. What workmanship warranty do you provide, and does it match the appliance guarantee?

7. Are parking, congestion or evening/weekend surcharges already factored into the price?

   
   

How to Avoid Surprises

• Access & Parking: Measure doorways and stairs; reserve a parking bay close to the kitchen.

• Isolation: Test cooker-control switch and circuit breaker before the installer arrives.

• Cabinet Dimensions: Confirm niche height/width against the new oven’s datasheet.

• Ventilation: Keep the room ventilated for the initial burn-off cycle.

• Power Capacity: Check consumer-unit spare capacity if the appliance draws >3 kW.

• Disposal Prep: Empty and clean the old oven to avoid mess when it’s removed.
