- How does location of your property change the price?Fuel and time on the road are built into the price. — ask before the quote rather than after.
- How does condition of your heating system change the price?The starting point matters as much as the finish you want. — ask before the quote rather than after.
- What is not included?Improved Heating Efficiency — by flushing out the system, power flushing can significantly improve heating efficiency — get the exclusions named in the quote, because a power flushing engineer job is priced on what was agreed and not on what was assumed.
BEFORE YOU BOOK
Check before you book
No register applies
NO REGISTER APPLIES TO PLUMBING ITSELF. Anyone may trade as a plumber. The line that does exist is gas: any work on a gas appliance or gas pipework is restricted to the Registered Gas Installer scheme, and a plumber who is not on it may not touch the gas side of a boiler however competent they are at everything else. Ask which side of that line your job falls on before you book.
Look for the trader badge and the ID-checked badge on the Locufy profile — both are checked by us, not claimed by the provider.
What to check instead
Whether any part of the job touches gas — if it does, the gas register applies and a plumbing qualification is not a substitute; A trade qualification or apprenticeship, which is voluntary but checkable; Public liability insurance, and who the insurer is; Whether they carry the parts or price them separately; A written scope naming what is isolated, drained and reinstated; How a leak discovered mid-job changes the price, agreed in advance.
Ask for each of these before you agree a price, and get the answers in the same message as the quote.
Insurance
Expect public liability, and ask specifically about water-damage cover. From a company, ask for the insurer, the limit and the VAT number, and ask who actually attends: the team that turns up may be employed, subcontracted or both, and only one of those is supervised by the firm you are paying.
Ask to see the current certificate of insurance — the insurer's name, the limit and the date it runs to.
Trader or private seller
Under the Consumer Rights Act 2022 a trader must tell you they are a trader, and your consumer rights — work carried out with reasonable skill and care, and a cooling-off period on a contract agreed in your home or online — apply to traders and not to private sellers. On Locufy the trader status is shown on the profile.
Look for the trader badge on the Locufy profile, and ask anyone else for it in writing before you agree a price.
VAT
VAT at 13.5%, the reduced rate Revenue publishes for this service. Ask whether the price you were given includes it. A trader under the €42,500 registration threshold does not charge it; one over it must, and must show it separately.
Ask whether the figure you were given includes it, and for the VAT number if they are registered — Revenue publishes the rate for this service. revenue.ie →

AFTER
When the job is done
Hiring a power flushing engineer: questions people ask
The cost of power flushing can be influenced by the size of your heating system, the extent of blockages, and the location of your property. More complex systems or severe blockages may require additional time and resources, leading to higher costs.
A typical power flushing job can take anywhere from 3 to 6 hours, depending on the size of the system and the severity of the issues. More extensive systems or significant build-up may require additional time.
Emergency power flushing services may be available, but they typically come at a premium. It's best to check with local service providers for their availability and any associated costs for urgent requests.
Yes, many service providers offer the option to combine power flushing with other plumbing tasks, such as radiator installation or boiler servicing. This can often lead to cost savings and increased efficiency.
Power flushing generally does not include repairs to existing leaks, boiler replacements, or installation of new radiators. It's important to clarify with your service provider what is covered in their power flushing service.
