How much does mould removal cost in the UK? (2026 guide)

Updated 6 November 2026 · By the Mould Cleaning team

Short answer: In 2026, professional mould cleaning in the UK usually costs £200 to £400 for a single room or bathroom, and £700 to £3,000 to treat a whole house, depending on how widespread the mould is. A mould or damp inspection typically costs £100 to £300, and fixing the cause, such as fitting a better extractor fan, is usually priced separately.

Typical prices

Job	Typical UK price (2026)
Mould cleaning, single wall or small area	£150 to £250
Mould cleaning and treatment, one room	£200 to £400
Bathroom mould clean including resealing	£250 to £450
Several rooms or half a house	£400 to £1,600
Whole house mould treatment	£700 to £3,000
Mould or damp inspection	£100 to £300
Bathroom extractor fan supplied and fitted	£200 to £450

These are typical guide prices. Your actual price depends on the size and number of areas affected, how deep the mould has gone, whether sealant or finishes need replacing, access and where in the UK the property is.

What affects the price

Total area of mould and how many rooms are affected
Surface type, as porous plaster and wood take more work than tiles
Whether silicone sealant needs cutting out and replacing
Anti-mould painting and redecoration afterwards
High ceilings and stairwells that need access equipment
Whether an inspection or damp survey is needed to find the cause

Cleaning is only half the job

Mould returns if the moisture is still there. Budget for the fix as well as the clean, whether that is better extraction, more consistent heating, repairing a leak or treating penetrating damp. Fixing the cause is often what saves money in the long run.

How to get an accurate price

Send clear photos of each affected area, rough measurements, and a note of where in the property it is and how long it has been there. That is enough for a fixed price in most cases.
