An Alternative to Aspect for Leak Detection in London

Aspect are a genuinely transparent multi-trade operator and a reasonable call for most London maintenance work, but they run one leak detection service inside a 24-trade business, charge by the half hour with rates that change by time of day, and quote from £54 plus VAT per half hour as at 19 September 2026; we do leak work only, at £150 per hour that does not change in the evening, with no find, no fee.

Start with what Aspect do well

Aspect are the strongest competitor in this market and it is not an accident. Three things on their own site explain most of it.

They publish their prices. Their rate guide sets out half-hourly rates by trade and by time of day rather than hiding cost behind a callback form, and their plumbing page carries the arithmetic through to a minimum charge. Very few London maintenance firms will do that. They also state that they do not charge for parking, fuel, the Congestion Charge or ULEZ, which removes the most common source of an unexpected line on an invoice.

They publish checkable credentials. Their accreditations page lists a Gas Safe registration number and a Refcom certificate number, not just badge images, which means you can verify them yourself rather than take the logo on trust.

And they are broad. Twenty-four trades from one company means one point of contact when a job turns out to involve three of them, which is a real advantage on an older London property where a leak, a damp wall and a failed extractor are one visit rather than three.

If you came here looking for a reason not to use Aspect, that is the honest answer to most maintenance jobs: they are fine, and often the right call. What follows is the narrower question of hidden water leaks.

What leak detection costs with them

All figures below were read from Aspect's own pages on 19 September 2026. Their rate guide states that published rates are starting-from figures and that the actual rate varies by postcode, so treat them as a floor rather than a quote, and check the live page before you rely on them.

Published rate	Figure
Leak detection	From £54.00 + VAT per half hour
Plumbing, weekday 7am–5pm	From £42.75 + VAT per half hour
Plumbing, late night 9pm–7am	From £72.00 + VAT per half hour
Minimum charge	One hour, then by the half hour rounded up
Plumbing minimum, weekday	£85.50 + VAT
Plumbing minimum, late night	£144.00 + VAT

Two of those lines together decide what a leak visit costs. The leak detection rate is £54.00 plus VAT per half hour and the minimum charge is one hour. That arithmetic is ours rather than a figure Aspect publish, but it is not complicated: the first hour of a leak investigation comes to £108.00 plus VAT, before parts, and before whatever the postcode adjustment does to the starting-from rate.

Their terms are worth reading before you book rather than after. Cancelling two hours or less before the slot carries a £50 plus VAT charge, and if the tradesperson has already arrived you are liable for an hour at the standard rate. An accepted estimate can be adjusted if the information you gave turns out to be wrong or if material costs rise by more than 10%. Completed work carries an undertaking to repair or make good any defect appearing within 12 months, subject to the exclusions in the terms.

Where we are actually different

Not on capability. Their leak detection page names thermal imaging, tracer gas, acoustic survey, moisture meters, borescope, pressure testing and more, which is the same toolkit we use, and unlike most of the specialists in this market they offer reinstatement as well as detection and repair. Anyone telling you Aspect only find leaks and walk away has not read their site.

The differences that survive scrutiny are these three.

One rate, all hours

Our rate is £150 per hour, agreed before we attend. It does not rise because it is seven in the evening, because it is Saturday, or because the property is a fourth-floor flat with a shared riser. Aspect's model prices time bands separately, which is defensible and clearly disclosed, but it means the cost of a leak that only shows itself when the heating runs in the evening depends partly on the clock.

No find, no fee

If we do not find the leak, you do not pay for the time we spent looking. That is not a discount, it is the whole risk of a failed investigation moving from you to us, and it is the single reason to give a specialist the job rather than paying for an open-ended search. Whoever you end up using, ask them what happens to the bill if the leak is not located, and get the answer before the visit rather than after it.

Depth rather than breadth

Aspect run one leak detection page inside a business covering 24 trades. We run one trade. In practice that shows up in the unglamorous parts: knowing that a warm patch two metres from the manifold is usually the manifold and not the pipe, that a screed floor will hide a pinhole for months because the heating keeps drying it, and that a stain on a ceiling below a bathroom is more often a failed shower tray seal than a pipe. It also shows up in the report. Ours is written to be accepted by an insurer for a trace and access claim, because that is what most of our detection work turns into.

What the review platforms say

Two platforms, two different pictures, both read on 19 September 2026. Trustpilot showed a TrustScore of 3.9 from 21,385 reviews, with 71% at five stars and 19% at one. Reviews.co.uk showed 4.8 from 1,779 reviews. We are not going to tell you which is the real number, because we do not know, and the honest thing is to give you both with the counts attached and let you read them yourself.

Trustpilot's own summary of the recurring themes is more useful than either score. The positive themes are professional engineers who explain the work, prompt arrival and thorough problem-solving. The critical themes are pricing level and unexpected charges, clarity of billing communication, and responsiveness when a complaint is escalated. The profile also shows the company replying to 90% of negative reviews, typically within a week, which is a higher engagement rate than most firms in this trade manage.

Read that as a pattern rather than a verdict: the engineer is generally the strong part and the invoice is generally the friction. If you use them, get the expected number of half hours agreed in writing before work starts.

When Aspect are the better call

Your job spans several trades, or you do not yet know which trade it is.
You are outside London. They cover the South East and East Anglia; we do not.
You need air conditioning, roofing, electrics or glazing, none of which we do.
It is a short job with a clear cause, like a leaking isolation valve under a sink, where a one-hour minimum charged in half hours is cheaper than an hourly specialist.
You want a single supplier with a long accreditation list for a managed property or a block.

When to call us instead

Water is appearing and nobody can say where it comes from. That is the job we are built for, and the one where no find, no fee changes the maths.
The floor or ceiling will have to come up, and you want the same firm to put it back. Our making good is done by our own handymen and builders, not subcontracted after the fact.
You are claiming on insurance and need a trace and access report that an insurer will accept.
Your boiler keeps losing pressure and two plumbers have already failed to find why. That is usually a job for tracer gas on a drained circuit, not another plumber.

When neither of us is the answer

Plenty of leaks do not need a detection visit from anyone. A tap that drips from the spout is a washer or a cartridge. Water pooling at the base of a shower screen after every use is usually the sealant rather than a pipe. A patch on a ceiling directly under a bath that only appears after someone showers is a tray or grout failure nine times out of ten, and re-sealing it costs the price of a tube. A boiler you top up once a year is behaving normally. Rule those out first, and if you can see the water coming from a joint you can reach, you want a plumber for an hour, not a leak investigation.

If you are past that point and nobody can tell you where the water is coming from, book an engineer.

Frequently asked

Is Aspect expensive for leak detection?

Their published leak detection rate was £54.00 plus VAT per half hour with a one-hour minimum when we read their rate guide on 19 September 2026, which works out at £108.00 plus VAT for the first hour on our own arithmetic. Their rate guide also states that these are starting-from figures that vary by postcode, so the live page is the only reliable answer for your address.

Does Aspect charge a call-out fee?

Their plumbing page states that there is no call-out fee for a plumber but that there is a one-hour minimum charge, and their rate guide states that parking, fuel, the Congestion Charge and ULEZ are not charged. Parts and materials are charged separately. All read on 19 September 2026.

Do Aspect repair the leak and put the floor back, or only find it?

Their damp and leaks page describes trace and access investigation, water leak repairs and full reinstatement of water-damaged areas, so all three are offered. That is unusual among firms that do leak detection, and it is one of the dimensions where we are not claiming an advantage over them.

What is Aspect rated on Trustpilot?

On 19 September 2026 their Trustpilot profile showed a TrustScore of 3.9 from 21,385 reviews, with 71% five-star and 19% one-star. On the same day Reviews.co.uk showed 4.8 from 1,779 reviews. Both figures are given here with their counts because the two platforms disagree and we are not in a position to say which better reflects the business.

How is your pricing different from Aspect Maintenance?

We charge £150 per hour, fixed before we attend and unchanged for evenings, weekends or difficult access, and we do not charge for the time spent looking if we do not find the leak. Aspect charge published half-hourly rates that differ across four time bands, with a one-hour minimum, and their rate guide states that the rates vary by postcode.

Should I use a multi-trade company or a leak specialist?

If the fault is visible and the trade is obvious, a multi-trade company is usually the faster and cheaper route. If water is appearing and nobody can say where from, a specialist is worth it, mainly because the search is the expensive part of the job and no find, no fee moves the cost of a failed search off you.
