Type that phrase into Google and you get a map pin and a column of nearby firms. The honest answer first: no UK law requires a local assessor, or any named provider. The duty is to make sure the assessment is done by someone competent who has actually looked at your building [1][2]. Distance is a convenience-and-cost question, not a compliance one.
That matters because “near me” quietly assumes local means safer, faster, or somehow more legitimate. For most landlords and small business owners, the postcode of the assessor’s office is not what determines whether the assessment holds up if the HSE, your insurer, or an incoming buyer ever asks to see it.
Why “near me” feels like the right search
It is a sensible instinct. You want someone who can come out this week, who answers the phone, and who you could chase if something goes wrong. A firm three streets away feels accountable in a way a name on a national website does not.
The instinct is right about one thing and wrong about another. It is right that someone has to physically attend your site. It is wrong to treat the office location as a proxy for that. A national company can dispatch an assessor who lives ten minutes from your door; a “local” firm can quote you a desktop-only assessment they complete from a laptop without ever seeing your tank, your calorifier, or that dead leg behind the boiler. The second one is the real problem, and it has nothing to do with miles.
Local vs competent: myth meets reality
Here is where the buying assumptions usually go wrong, and what actually holds true.
| The assumption | The reality |
|---|---|
| ”The law says I need a local company.” | No law names a provider or a radius. The requirement is a suitable and sufficient assessment by a competent person [1]. Location is not a legal criterion. |
| ”Local means they’ll definitely visit the site.” | Not automatically. An adequate assessment normally needs a physical survey of the actual system; a cheap desktop-only report from a nearby firm is the weaker option [3]. Ask who attends, not just where they’re based. |
| ”A national firm won’t really turn up.” | Most operate through regional or self-employed assessors. What you should pin down is whether the same competent person surveys your site or whether the visit is subcontracted to someone unvetted. |
| ”Closer is always cheaper.” | Travel time can be a real line in the quote, so a distant firm may cost a little more. But a local quote padded with annual retests you don’t need will dwarf any mileage saving. Compare scope, not just proximity. |
| ”Local knowledge of the water makes the assessment better.” | Your supply’s hardness and temperature are read on the day, on site, against your system. Competence and a thorough survey matter far more than the assessor having grown up nearby. |
The pattern is consistent: the things people credit to “local” are really things they should credit to competence plus an actual site visit. Those can come from a firm next door or one an hour away.
What proximity genuinely does buy you
Local is not worthless. Two advantages are real, and worth weighing.
The first is travel cost. An assessor based far away may add travel to the quote or batch your job onto a day that suits their route rather than yours. For a single small property this can nudge the price up. If you want to understand what drives that figure, How much does a Legionella risk assessment cost in the UK? breaks down the cost components so you can see where mileage actually sits.
The second is response speed for follow-up. If a sentinel temperature looks wrong, or you need a quick re-survey after pipework changes, a provider who covers your area routinely can usually get back sooner than one who passes through quarterly. That is a service-level point, not a legal one, but it is genuine.
Neither advantage outranks competence. A nearby assessor who misses a redundant blind end or never opens the cold water storage tank has cost you far more than the travel charge you saved.
How to vet a provider’s real coverage of your area
Instead of trusting the map pin, confirm three things directly. This is the part that separates a compliant assessment from a tidy-looking PDF.
- Confirm they physically attend. Ask plainly: “Will someone survey the system on site, and what does that survey include?” An adequate assessment inspects the real plumbing — tanks, calorifiers, outlets, dead legs — not a phoned-in description [3]. A quote that never mentions a visit is the red flag, whatever the distance.
- Confirm who actually does the work. Will the competent person who scoped the job attend, or is the visit subcontracted? If it is passed on, ask how that person’s competence is checked. Who is qualified to perform a Legionella risk assessment? sets out the training and experience to look for.
- Confirm coverage in writing. Registered providers under the Legionella Control Association declare the areas and services they cover [4]. Ask them to state, by postcode, that they service your location and what their travel charge is — rather than inferring it from a “we cover the South East” banner.
- Confirm the scope matches your building. A landlord’s flat and a small office have different systems. The right questions to put to any firm — local or national — are gathered in How to choose a Legionella risk assessment company (questions to ask).
Run those four checks and “near me” stops being a filter and becomes what it should be: a tie-breaker between two competent providers who both genuinely cover you.
This is general guidance to help you choose well, not legal advice or a verdict on any particular firm. Your own duty to assess and control the risk in the water system you’re responsible for sits with you regardless of who you appoint, and the right scope depends on your building — which is exactly why a competent, site-specific assessment matters more than a postcode [2].
Common questions
Is a local Legionella risk assessment legally required?
No. UK guidance asks for a suitable and sufficient assessment by a competent person; it names no preferred location, firm, or distance [1]. A well-run national provider can satisfy the duty as fully as the firm on your high street.
Is “Legionella testing near me” the same as a risk assessment?
No, and the distinction trips people up. Water sampling — sending samples to a lab for a Legionella count — is testing, and it is not the same as the assessment of your whole system. Most lower-risk buildings need a risk assessment and ongoing control, not routine sampling. Be sure the quote you accept matches what you actually need.
Will a national company really send someone to my property?
The good ones do, usually through a regional or self-employed assessor near you. The thing to confirm is not the head-office address but whether the same competent person attends your site or the visit is subcontracted to someone whose competence you cannot see.
Does using a company further away cost more?
It can, because travel time may appear in the quote, but it is rarely the biggest factor. Scope, system complexity, and whether you’re sold retests you don’t need move the price far more. If you let or sell property, Do I need a Legionella risk assessment to let or sell my property? explains when the duty actually applies before you spend anything.
Your next step
Open the website of the nearest firm you found, plus one provider whose reviews you trust even if they’re further out. Send both the same short message: confirm you cover this postcode, confirm a competent person will survey the system on site, state the travel charge, and tell me what’s included. Compare the two replies on competence and scope — not on the map. The clearer, site-visit answer wins, wherever its office is.
