In short
What does a legionella risk assessment in Harrow involve?
A legionella risk assessment in Harrow involves checking stored water, temperatures, deadlegs and unused outlets, and EliteShires Property Services leaves the dated written assessment for HA1 to HA3 lets on the day.
No legionella certificate exists, and HSE accepts that a competent landlord may assess their own property, so book us if you want it measured and written up. The price is fixed before we attend. Valuation Office figures put 51.8% of Harrow's homes in the 1919 to 1939 bracket (March 2025), an age more likely to still have a cylinder or loft tank.
The full guide is on our Legionella Risk Assessment page, and everything else we do locally is under landlord certificates and repairs in Harrow.
If the assessment recommends pipework changes, they are quoted through plumbing in Harrow, and you are free to use anyone.
We attend in and around Harrow, including Harrow town centre, Wealdstone, North Harrow, South Harrow, West Harrow, Harrow on the Hill and Harrow Weald.
Legionella Risk Assessments in Harrow: what is different here
Which Harrow houses are most likely to store water?
Older and interwar houses are the ones to check first. Valuation Office figures for March 2025 put 51.8% of Harrow's homes in the 1919 to 1939 bracket, against 22.4% across London. The 1930s alone account for 41.6%. Houses of that age were often built with a cold tank in the loft feeding a hot water cylinder, and some still run that way after decades of upgrades. Pre-1919 houses are fewer, about one in ten, and cluster around West Harrow, Wealdstone and Harrow on the Hill.
No public dataset says how many Harrow homes still store water, so we never assume. Tell us what heats your water when you book. A combi with no tanks points to a short visit. A cylinder or an airing cupboard full of pipework means more to measure and record.
What changes when a Harrow house has been split into flats?
A converted house can put several households on pipework that was laid out for one family. At the 2021 Census, 26.5% of households in Marlborough ward lived in part of a converted or shared house, against 6.4% across the borough. Headstone, West Harrow and both Wealdstone wards each sat above 10%. In these buildings, start by finding where each flat's water comes from. If every flat has its own combi, each landlord assesses their own system.
If a tank or cylinder in a shared loft or cupboard still serves more than one flat, someone has to own it, and the lease usually decides who. We trace the pipework back from your stopcock, note what is shared, and say in the written assessment which parts sit outside your control.
Is a legionella assessment one of Harrow's licence conditions?
No: the HMO standards and selective licence conditions that Harrow publishes on its licensing pages contain no legionella condition (checked October 2026). Their water clauses ask for an adequate supply of cold and constant hot water to every bath, shower and basin, and no unreasonable interruption to supply. The duty to assess comes from health and safety law instead, as our main legionella page explains. So a Harrow licence neither covers the assessment for you nor asks for a separate certificate.
Where licensing does change the job is the layout it requires. Harrow's HMO amenity standard asks for two bathrooms and two separate WCs once a house has six to ten occupiers. Extra bathrooms mean outlets that may sit idle when rooms are empty, and those go on the assessment with a flushing routine.
When should a Harrow landlord ask for a fresh assessment?
Ask when the water system changes or the way the house is used changes. Typical Harrow triggers are a loft conversion with a new shower room, a combi replacing an old cylinder, or a family house becoming a small HMO for three to six sharers. Since 11 June 2026 that change needs planning permission across the borough under Harrow's Article 4 direction. A long empty spell is the other trigger.
Since 1 May 2026, assured tenancies run as periodic tenancies with no fixed end date, so changeovers are harder to plan around. Treat each genuine void as a review point. Run every outlet, check the cylinder setting, and update the record if anything has moved. HSE does not insist the findings are written down, but a dated record is the simplest proof you took the steps.

Legionella Risk Assessments in Harrow: your questions
Not answered here? Call 0203 667 1333 and ask.
My Harrow semi still has a tank in the loft. Does that make it high risk?
Not automatically. A loft tank raises the questions an assessment answers. Is the lid tight-fitting? Is the tank insulated and free of debris? Does the cylinder store hot water at 60°C? A clean, lidded tank feeding a well-set cylinder can still be low risk. If the tank is open or dirty, we say so in the written assessment and list the fix.
I own one flat in a converted house in Wealdstone. Is the shared tank my problem?
Only the parts your lease makes yours. Pipework and storage that serve your flat alone are your responsibility as landlord. A tank or cylinder serving several flats usually falls to the freeholder. We record which is which, so you can ask the freeholder or managing agent what checks they carry out on the shared parts.
Do I need a new assessment every time a room changes hands in my Harrow HMO?
No. One assessment covers the water system of the whole house, and a new tenant in one room does not change that. What matters is the empty room in between. If it has its own basin or en-suite, run the taps and shower each week until the room is let, and note it down.
Will Harrow Council ask to see a legionella assessment when I apply for a licence?
The licence conditions Harrow publishes do not list one, so it is not a standard part of the application. The duty to assess still applies to every let under health and safety law. Keep the dated assessment with your gas and electrical paperwork, so your property file is complete if anyone asks.
Can you assess my Harrow let on the same visit as other landlord checks?
Yes. A legionella visit is usually short, so it often fits alongside a gas safety check or an EICR at the same address. Each is priced separately and confirmed before we attend. You arrange access once, and the written legionella assessment is left with you on the day.
