What woodworm treatment costs
Published UK prices for woodworm treatment vary, because jobs differ in size, access and method. Most sources put a single room in the hundreds of pounds and a whole house at around £800 to £1,000 or more. Severe cases cost more.
The table below uses figures we could read on the source pages on 9 October 2026. We have not added any price of our own. Treat the numbers as a guide, because only a survey and a written quote can give an exact figure.
| Job | Rest of UK | London and South East |
|---|---|---|
| Survey | £80 to £180 | £100 to £220 |
| Single room or contained area | £300 to £500 | £360 to £650 |
| Several rooms or a large loft | £500 to £800 | £650 to £1,000 |
| Whole-house treatment | £800 to £1,000+ | £1,000 to £1,300+ |
What other price guides say
Loft treatment
MyJobQuote gives £800 to £1,000 for a 25m² loft, because tricky access adds time.
Fogging and fumigation
MyJobQuote lists £500 to £600 for 15m², £700 to £800 for 25m² and £900 to £1,000 for 35m².
Surveys
MyJobQuote lists £80 to £130 for a one or two bed home, and £200 to £250 for a large one. DampHub says £80 to £250.
Timber repairs
DampHub estimates £200 to £500 for small repairs and £1,000 or more for large beams or several joists.
Six things that change the quote
Area treated
This is the biggest factor. A single floor costs far less than a whole house, because the price follows the amount of timber.
Access
Open joists are quick to treat. Lifting fitted floors or working in a cramped loft adds labour.
Severity
A light, early case needs a simple spray. Heavy damage may need paste, extra visits or repair.
Species
Furniture beetle responds to standard methods. Death watch beetle in old oak may need a specialist approach.
Timber repair
Weak joists and rafters need repair as well as treatment. Repair is priced separately, and it explains the top of most ranges.
Damp
Woodworm follows damp. If a leak or rot needs fixing first, that work is quoted alongside.
What a good quote should show
Compare at least two written quotes, because scope and method differ between firms. A cheap quote that covers half the timber is not a bargain.
- The beetle that was found and how the surveyor knows it is active
- The method, the timber covered and the price, including VAT
- What happens if beetle returns, written down rather than promised by phone
- Any repair or damp work, priced as a separate line
Woodworm treatment cost: your questions
How much does woodworm treatment cost in the UK?
Published guides put a single room at about £300 to £500 and a whole house at £800 to £1,000 or more. London and the South East cost more. The only exact figure comes from a survey and a written quote.
Why does a whole house cost so much more than one room?
It covers far more timber, often across the loft, floors and several rooms. It may also include repairs where the beetle has weakened joists. Our cost guide goes through each area.
Is DIY cheaper?
A tin of woodworm killer costs far less than a professional job, and it can work on small items. For floors, roofs and structural timber it may not reach deep enough. Read DIY vs professional treatment.
Do prices include VAT?
It depends on the source, so always ask. The Fantastic Services table states that its figures include VAT. A written quote should say clearly whether VAT is included.
Do I pay for the survey?
Practice varies. Some firms credit the survey fee against work, and some surveys are free. Ask before you book. See what a survey covers.
Want a price for your own home?
Request a survey, because only a visit gives an exact figure. A local specialist will call to arrange it.
