Interior work is where most decorating money is spent and where quotes vary most. The published guides give a workable frame, as long as you read them as national averages with the caveats attached.
Room by room, at published 2026 rates
| Room | MyJobQuote | Checkatrade |
|---|---|---|
| Box room | £175 to £300 | not listed |
| Small bedroom, 10 to 12m² | £250 to £400 | £350 average (small room, 8m²) |
| Large bedroom, 14 to 20m² | £350 to £660 | not listed |
| Medium room, about 12m² | about £400 | £450 average (18m²) |
| Large living room, 20 to 30m² | £500 to £990 | £1,000 average (30m²) |
| Hall, stairs and landing | £875 to £1,330 and up | £1,600 average |
Both guides read 4 September 2026. For whole properties, Checkatrade publishes £1,500 to £2,500 for a 2 bed flat and £5,500 to £7,500 for a 5 bed house, averages £2,000 and £6,000.
What moves an interior quote
Prep is the honest variable. Filled cracks, stripped paper, stain blocking and furniture moving can add a day before a brush touches emulsion. Ceiling height, colour changes from dark to light, and trade versus premium paint do the rest. London adds a fixed layer: MyJobQuote prices a standard 15m² room at £450 to £570 in London against £360 to £465 nationally.
If you are the decorator
These published averages are your competition for the first impression. Publish your own room examples with photos and honest ranges, dated. A page that says “medium bedroom in Nottingham, two coats, woodwork included, £380 to £450, March 2026” is the page a search engine quotes and a customer trusts. Fewer than half of business sites publish any price at all, per our price transparency study, so the bar is low.
Common questions
How much does it cost to paint a bedroom in the UK?
At published 2026 rates, a small bedroom costs £250 to £400 and a large bedroom £350 to £660 per MyJobQuote, while Checkatrade lists a £350 average for a small room. Read 4 September 2026.
How much to paint a whole house interior?
Checkatrade publishes £1,500 to £2,500 for a 2 bed flat and £5,500 to £7,500 for a 5 bed house at 2026 rates. Condition and prep move these ranges significantly.
What makes interior painting quotes vary?
Preparation is the biggest factor: filling, stripping, stain blocking and moving furniture add time before painting starts. Ceiling height, colour changes and paint grade follow, and London adds roughly 20 to 25% on published room prices.
