Most problems we see on installation day start at the planning stage: a unit that is 20 mm too wide, a tall housing that clashes with a window, or an appliance that needs a different socket. A careful plan saves money and time. These are the checks we recommend before you order.
1. Measure every wall at three heights
Walls in London homes are rarely straight. Measure each wall at floor level, at worktop height (about 900 mm) and near the ceiling, and use the smallest figure. Note the ceiling height in several places too.
2. Mark windows, doors, radiators and boxing
Record the position and size of every window, door frame, radiator, boiler, soil pipe and boxed-in pipe. Window sills often sit lower than the planned worktop height in period properties.
3. Locate water, waste, gas and electrics
Note where the stopcock, waste outlet, gas pipe and consumer unit are. Moving the sink or hob is possible, but it adds plumbing, gas or electrical work that should be in your budget from the start.
4. Allow for fillers and clearances
Kitchens need filler panels where units meet walls so doors and drawers can open freely. Leave space for oven door clearance, dishwasher doors and corner drawers, and check that tall units clear the ceiling and any cornice.
5. Plan the work triangle
The sink, hob and fridge should be close enough to work comfortably but not crowded. Keep at least some clear worktop either side of the hob and next to the sink.
6. Check appliance specifications
Integrated appliances need specific housings and ventilation gaps. Download the installation sheet for each appliance and compare it with the unit you are ordering.
7. Think about worktops early
Stone worktops need a template after the units are fitted, while laminate and wood are cut on site. Decide early so your timeline and budget are realistic.
Let a fitter check the plan
Retailer planners are useful, but they have not seen your walls. We are happy to visit, measure and review your plan before you place the order, whichever brand you choose. It is free, and it can save you an expensive reorder.
Frequently asked questions
Should I measure before or after removing the old kitchen?
Measure before ordering, but measure the walls rather than the old units. Old cabinets often hide uneven walls and pipework, so we always recheck once the room has been surveyed properly.
What height should my worktop be?
Most kitchens use a worktop height of about 900 mm. Taller households sometimes raise it slightly with taller plinths. Check window sill heights in period homes before deciding.
How much space do I need for an island?
As a rule of thumb, leave around 1 metre of clear walkway around an island, more if two people often cook together or if appliance doors open into the walkway.
Can you check a plan from IKEA or Howdens?
Yes. Send us the plan or bring it to the survey and we will compare it with the actual room, highlighting fillers, clearances and service positions before you order.
