Hydr review UK 2026: a fixed fee, a software gate, and three questions it has not answered

Read against hydr.co.uk including its FAQ pages, terms and on-site fee calculator, the Companies House record for HN Flow Ltd (12843859) covering charges, officers and persons with significant control, and Trustpilot.

The short answer

Hydr funds small B2B invoices digitally. It pays the full value of an invoice less one fixed fee within 24 hours, bundles credit protection into that fee, asks for no minimum term, and locks the fee once quoted even if the customer pays a few days late. Its own calculator shows the shape of the deal: a £3,000 invoice, a fixed fee of £118.50, £2,881.50 in the bank. That is the only published worked example any of the invoice funders on this part of our panel offers.

Two hard gates decide almost every case. The business must have been incorporated for twelve months or more, and it must use Xero, QuickBooks, FreeAgent, KashFlow or Sage200 Business Cloud. No accounting package means no facility, which Hydr confirms in as many words. England and Wales only, and the product is disclosed by design, so Hydr talks to the client's customers from the start.

It fits a small limited company with a handful of reliable trade customers and an average invoice in the low thousands. It does not fit anyone wanting confidentiality, anyone in Scotland or Northern Ireland, or anyone who needs a six-figure facility and a named relationship team.

Spans across Hydr products on our panel, checked September 2026. Shown per category, because one range across different product types would describe something no business can actually have. These are not offers, quotes or rates you will be given, and a dash means we hold no published figure for that field. All lending is subject to status and the lender's own checks. Naming a lender is a fact about our panel: it is not an endorsement of CapExpand by Hydr, and implies no affiliation. Panel composition changes.

The company behind the brand

Hydr is a trading name. The operating company is HN Flow Ltd, number 12843859, incorporated on 28 August 2020 and registered at Cubo, No.1 Spinningfields in Manchester. That connection is only discoverable from Hydr's own terms page, and it matters more than it sounds: searching Companies House for Hydr returns a cluster of unrelated companies in Wales and Dorset, none of which is this business. Anyone running a check should use the HN Flow name and number.

Its filed classification is business and domestic software development rather than any finance code, and Hydr's own terms describe what it sells as cloud-based technology services provided via the App, with the invoice purchase sitting behind that. Nicola Weedall, the founder and chief executive, has been the registered person with significant control since incorporation, holding between 25% and 50%. Co-founder Hector Macandrew ceased to be a person with significant control on 31 August 2024.

The published terms are out of date, which is a small thing that tells you something. They still give the registered office as 70 Buxton Street in London, an address the company left in July 2021, and they still define the App by pointing at a staging URL on a hosting provider. No FCA authorisation statement or reference number appears anywhere on the site, which is the correct position for unregulated business invoice finance, and we attach none to it.

What Hydr actually does

One product, tightly drawn. Hydr verifies the client's customer, then pays the full value of the invoice minus its fixed fee within 24 hours. There is no factoring, no whole-turnover discounting, no asset based lending and no trade finance. Credit protection is included on every invoice funded, and Hydr says the fee covers everything including that protection.

Selection happens at debtor level rather than invoice level. In Hydr's words the client chooses the number of debtors they wish to fund and Hydr looks after all of the invoices with that chosen debtor. So this is not cherry-picking one invoice from a customer and keeping the rest back, which is how a spot facility behaves. Pre-existing invoices can be funded as long as they are neither overdue nor disputed and verification succeeds.

Disclosure is a design decision rather than a fallback. Hydr states plainly that it is a disclosed product and that it wants the client's customers to know the two are working together. For a business that already has a comfortable relationship with its buyers that is fine and arguably simplifies collections. For a business worried about how a large customer reads it, this is the wrong funder, and no amount of asking will change it.

The one published worked example on this panel

Hydr runs a fee calculator on its homepage, and its default state shows real numbers: 100% of an invoice worth £3,000, a fixed fee of £118.50, and £2,881.50 received in 24 hours. That works out at 3.95% of face value. The calculator offers payment terms of 15, 30, 45, 60, 75 and 90 days and does not say which one the default corresponds to, so the percentage cannot be converted into a monthly or annual cost without asking, and we do not attempt it.

The structure around that fee is unusually clean. No setup fee, no onboarding fee, no subscription and no listing fee. Fees are calculated invoice by invoice, taking account of the customer and their payment history. And the quote does not move: Hydr says that once it has quoted a fee, that is what the client pays, and repeats elsewhere that the fee is unchanged even if the debtor is a couple of days late. Compare that with the late-payment mechanics elsewhere in this market, where being slow rather than bad is what triggers the charges, and the appeal for a small business is obvious.

No minimum fee is published, and no minimum or maximum invoice size appears anywhere on the site. Given the fee is set per invoice, a client with an unusual debtor should expect the number to reflect that rather than a rate card.

Who can use Hydr, and who is shut out

The eligibility list is four lines long and every line excludes somebody. A business must be registered in England and Wales, have been incorporated for twelve months or longer, sell to other businesses, and use one of five cloud accounting packages: Xero, QuickBooks, FreeAgent, KashFlow or Sage200 Business Cloud. Asked whether a business without an accounting package can use the service, Hydr answers sadly not.

Two of those bite harder than they look. The twelve month incorporation test is a company test, so a sole trader is effectively outside it, and Hydr never says sole traders are accepted; treat it as limited companies only and confirm if a case turns on it. The geography line excludes Scotland and Northern Ireland, which is narrower than every other invoice funder we deal with.

The software list is also inconsistent across Hydr's own pages. The eligibility answer names five packages, the paragraph immediately below it names seven including Clearbooks and FreshBooks, and a third page names six. We screen on the five in the eligibility list, because that is the one written as criteria, and check anything else with Hydr before an application. No minimum turnover is published and no sector exclusions are published, including for construction, so both are questions rather than answers.

Three things Hydr has not answered

The first is recourse. Hydr never uses the word, in either direction. Its marketing implies protection: every invoice funded is credit protected, and the FAQ answer to what happens if a customer ceases trading points at that protection. The same FAQ then says the client's obligations remain until all funded invoices are repaid, either by the client or by the debtor, which is recourse language. Those two statements can be reconciled, most likely by protection covering insolvency but not slow payment or dispute, but Hydr has not reconciled them in public. Nobody should describe this facility as non-recourse without written confirmation, and we ask for it.

The second is the funding line. HN Flow Ltd has no registered charges at all, none outstanding and none satisfied, which is unusual for a business that advances money against invoices. Every account of its funding refers to a major lending partner signed in September 2022 that has never been named. That is not a solvency point, and a client owes the funder rather than the other way round, but a business placing repeat volume is entitled to ask who is actually funding the invoices and under what arrangement.

The third is reviews. The homepage says Hydr is rated 5 stars by customers and names no platform. Its Trustpilot profile is unclaimed and carries no reviews at all, so there is no score there to support or contradict the claim, and the aggregates on another review site are mutually inconsistent enough that we will not quote them. Hydr also calls itself award-winning repeatedly without naming an award. There is a real one behind it: Hydr won Best Alternative Finance Provider at the British Bank Awards 2025, and it placed seventh in the BusinessCloud FinTech 50 for 2025. Both are more persuasive than an unattributed star rating, which makes the omission a puzzle.

The size of the operation, and what that means

Hydr is small and does not hide it. Its chief executive gave a headcount of four people, two of them part-time, in November 2025, with roughly £1 million a month advanced and an average invoice around £2,500, targeting businesses under £3 million of turnover. The site claims more than 11,000 invoices processed. A partnership with Finity, announced on 2 December 2025, combines payroll and funding for recruitment and payroll businesses.

Read those numbers as a description of fit rather than a warning. An average invoice of £2,500 and a monthly book of about £1 million tells you exactly which cases work here: small, regular B2B invoices from a company that already lives in Xero or QuickBooks and wants money in a day without a facility negotiation. It also tells you which do not. A client expecting a named relationship manager, a six-figure line or an on-site review is describing a different sort of funder entirely.

Onboarding is digital and quick: five to ten minutes on Hydr's own figures, requiring photo identification, read-only access to the accounting package and read-only access to the business bank account. There is no facility to negotiate, which is why setup is measured in minutes rather than the ten working days a traditional funder needs. Drawdown is stated as 24 hours from verification.

Who Hydr suits

A good fit if

  • Limited companies incorporated over twelve months with invoices in the low thousands
  • Businesses already running Xero, QuickBooks, FreeAgent, KashFlow or Sage200 Business Cloud
  • Clients who want the cost fixed at quote and unaffected by a debtor paying a few days late
  • Companies happy for their customers to know a funder is involved
  • Recruitment and payroll businesses, given the Finity integration announced in December 2025

Look elsewhere if

  • Sole traders, since the criteria require twelve months of incorporation
  • Businesses in Scotland or Northern Ireland, which fall outside England and Wales
  • Anyone needing confidentiality, because disclosure is built into the product
  • Clients who want to fund one invoice from a customer and keep the rest back
  • Businesses without a supported cloud accounting package, which Hydr treats as a hard no
  • Cases needing a six-figure facility or a named relationship team

Our verdict

For a small limited company with a supported accounting package and steady trade customers, Hydr is one of the tidier products in UK invoice finance. A single fixed fee that includes credit protection, no subscription, no tie-in and a quote that does not drift when a debtor runs late is a genuinely fair deal at this size, and the published calculator means a business owner can see what the money costs before speaking to anyone. That transparency is rare enough to be worth saying twice.

Our honest limitation is that three material things are unresolved in public: whether the facility is recourse, who funds it, and what the five-star claim refers to. None of those makes Hydr a poor choice, and all three are reasonable to ask before a first invoice is funded. We would send a small Xero-based B2B case here without hesitation and would not send a Scottish business, a sole trader or anyone needing confidentiality. Hydr sets its own criteria and its own fee; we arrange the introduction.

Hydr is on our panel. So are the lenders it competes with.

One enquiry and we check your numbers against Hydr and the rest of the panel before anything is submitted. We arrange; the lender decides.

Frequently asked questions

HN Flow Ltd, company number 12843859, incorporated on 28 August 2020 and based in Manchester. Every company at Companies House actually named Hydr is a different business, so any check should be run against HN Flow rather than the brand.
The full value less one fixed fee, within 24 hours of verification. Its own calculator shows a £3,000 invoice funded for a fixed fee of £118.50, leaving £2,881.50, which is 3.95% of face value. The calculator does not say which payment term that default assumes.
No. Hydr states it charges nothing to open an account or to onboard, and no subscription or listing fees. The single fee per invoice is calculated case by case, taking the customer and their payment history into account, and it includes credit protection.
Hydr says no: once the fee is quoted, that is what the client pays, and it does not change even if the debtor is a couple of days late. That is unusual in this market, where late payment normally triggers extra charges.
Hydr never uses either word. It says every funded invoice is credit protected, and it also says the client’s obligations remain until funded invoices are repaid either by the client or the debtor, which is recourse wording. Get the position confirmed in writing before relying on the protection.
Yes, or one of FreeAgent, KashFlow and Sage200 Business Cloud. Asked whether a business without an accounting package can use it, Hydr says sadly not. Other pages list Clearbooks, FreshBooks and Sage inconsistently, so check anything outside the five-package eligibility list first.
Effectively no. The criteria require a business incorporated for twelve months or longer, which a sole trader is not, and Hydr never states that sole traders are accepted. Treat it as limited companies only and confirm if a specific case depends on it.
No. The eligibility criteria require a business registered in England and Wales, which is narrower than the other invoice funders on our panel. A Scottish company needs a different provider.
Yes, by design. Hydr states that it is a disclosed product and that it wants customers to know the two businesses are working together, and it manages those customers from the start. Confidentiality is not available.
No. Selection is by debtor rather than by invoice: the client chooses which customers to fund and Hydr looks after all of the invoices with that customer. A business wanting to fund one invoice and hold the rest back needs a spot provider instead.
It has none. The Trustpilot profile is unclaimed and carries no reviews, so the homepage claim of being rated 5 stars by customers names no platform we can check. Hydr did win Best Alternative Finance Provider at the British Bank Awards 2025 and placed seventh in the BusinessCloud FinTech 50 for 2025.
Not publicly established. HN Flow Ltd has no registered charges at Companies House, and coverage of the business refers only to an unnamed major lending partner signed in September 2022. That is a fair question for a client placing repeat volume, rather than a reason for concern about an invoice already funded.
