Inside the home
What decides the cost of painting your interiors.
Interior painting costs are driven less by the paint than by the state of the walls underneath it and by whether you are living in the house while it happens.

At a glance
What makes interior painting cost more or less?
Preparation depth first, then measured area. A sound wall needing a clean and two coats is a fraction of the work of one needing full putty, levelling and priming. Occupancy matters too: working around furniture and a household takes longer than an empty flat.
Measured wall and ceiling area
Every wall and ceiling in scope is measured, less doors and large windows. Rooms of the same nominal size differ more than people expect — a long narrow room has considerably more wall than a square one of equal floor area.
In order of impact
What moves the number.
Listed largest first. If a quotation is silent on the ones near the top, that silence is itself the answer.
Preparation depth
Touch-up and recoat, full putty and levelling, or removal back to sound plaster. This decides most of the number.
Whether ceilings are included
Ceilings add measurable area and are slower to coat evenly than walls.
Colour change
A strong change, particularly dark to light, can require an additional coat or a tinted primer.
Product grade and washability
Kitchens, hallways and children's rooms usually justify a more washable finish than bedrooms.
Occupancy and furniture
An occupied, furnished home takes longer to protect, work and reinstate each day.
Joinery and detail
Cutting in around wardrobes, panelling and cornices is slow work that a flat area figure hides.
Method
How we build the quotation.
There are no figures here because none has been approved for publication. What follows is the sequence, so you can check anyone's quotation against it.
- Room-by-room measurement of walls and, if in scope, ceilings.
- Condition assessment per wall — cracks, hollow plaster, chalking, moisture.
- Preparation specified and priced separately for each surface.
- Product and coat count agreed for each room's use.
- Protection and daily reinstatement allowed for where the home is occupied.
- Exclusions listed: structural repair, damp treatment, electrical, deep cleaning.
Interior Painting Cost — your questions.
Is it cheaper to paint the whole house at once?
Usually yes, per unit of area. Setting up, protecting and demobilising happen once rather than repeatedly, and material is bought in one go. Whether that suits your budget and household is a separate question.
Does an empty house cost less to paint?
Generally, yes. There is no furniture to move and protect, no working around a household, and the team can run a room to completion without interruption. If you can time the work before moving in, it usually helps.
Do ceilings really add much?
They add real measured area and take longer per square foot than walls, because working overhead is slower and lap marks show more. They are quoted as their own line so you can decide.
A measured quotation costs nothing.
We measure the property, assess the surfaces and issue an itemised quotation you can hold us to. There is no charge and no obligation.
- We call you back the same day to get a picture of the property and the surfaces.
- We agree a time and come out for the free inspection.
- You get the written scope and itemised quotation.
- Nothing starts until you approve it.
