HomeServe's Plumbing and Drainage Plus policy costs 50p a month for the first year — £6 for the whole twelve months — and pays up to £4,000 a claim, with no cap on the number of claims you make. The excess is £30 each time. Figures checked on 14 September 2026 against HomeServe's own product page and its Insurance Product Information Document.

The firm behind that price is one of the largest home emergency operators in Britain. HomeServe Limited reported 3,621,000 customers and revenue of £976.3m for the year to 31 March 2023, a retention rate of 82%, more than 6,000 staff with roughly half of them in the UK, and about 700 directly employed engineers rather than a list of subcontractors. Aviva Insurance Limited carries the risk. HomeServe Membership Limited sells, arranges and administers the policy, and publishes the full terms and the product information document on the buying page rather than after payment.

Two dates matter before you click. The 50p offer runs to 15 September 2026, after which the introductory price for new customers becomes £1 a month. And HomeServe prints the second-year figure on the same page as the first: £16.45 a month, or £197.40 for the year, for a customer who has not claimed. Sellers of this kind of cover rarely put the renewal price next to the offer price, and the arithmetic further down this page only works because this one does.

The cover itself: £4,000 a claim, £30 to open one

The policy is written around five named problems: leaking pipes inside the home, blocked drains, blockages to sinks and toilets, leaks or blockages to the water supply pipe, and dripping or seized taps. Each claim is met up to £4,000 in value, and the number of claims in a year is not capped. Where a part cannot be sourced within 28 days, or a repair would cost more than 85% of the price of a new appliance, the terms allow a replacement instead of a repair.

Set that £4,000 against the premium and the shape of the product becomes clear. At the second-year price of £197.40 a year, a single claim taken to the ceiling is worth just over twenty years of premiums. That is what a cheap indemnity policy is for, and it is a genuinely useful ceiling — the cover is not thin, it is narrow.

The £30 excess is charged per separate problem registered, by card, before an engineer is despatched. In the first year that single excess is five times the £6 the policy itself costs. A year with three unrelated jobs in it carries £90 of excess on top of whatever the premium was.

There is also a 28-day exclusion period running from the start date, and from the date of any change to the cover. A leak that appears in the fourth week of the policy is not a claim.

£6, then £197.40: the two-year sum

HomeServe publishes both numbers, so the sum is not a discovery. Year one is £6. Year two, for a customer who has made no claim, is an expected £197.40. Two years of continuous cover is therefore £203.40, an average of £8.48 a month across the twenty-four months, and the year-two monthly price is 32.9 times the year-one one.

Add claims and the gap widens. Two separate jobs in the second year put the year's outlay at £257.40. A customer who has claimed should also expect a different renewal figure again, because the terms state that claims history is taken into account when the renewal price is set.

None of that makes the offer a bad one. It makes the 50p a customer acquisition price rather than the price of the cover, and the honest way to judge it is to ask whether £197.40 a year is what you want to pay for a £4,000 drain and pipe indemnity with a £30 excess. The first year is close to free either way. The policy renews automatically, with a reminder before it does, so the decision arrives whether or not you go looking for it.

Who answers the phone, and who pays the bill

Two companies stand behind this policy and they do different jobs. Aviva Insurance Limited, registered in Scotland under company number 2116 and regulated by the Prudential Regulation Authority and the Financial Conduct Authority, is the insurer — it carries the risk and it funds the claims. HomeServe Membership Limited, registered in England and Wales under company number 02770612 and holding Financial Conduct Authority firm reference 312518, sells the policy, arranges it, administers it and sends the engineer.

The company was incorporated on 3 December 1992 and has traded under four names since; it became HomeServe Membership Limited in April 2008, and its registered office is Cable Drive, Walsall WS2 7BN. Its parent, HomeServe Limited, left the London Stock Exchange in January 2023 when Brookfield completed a take-private valuing the group at about £4.1bn.

Complaints go to HomeServe rather than to Aviva: 0330 0247 999, or customerrelations@homeserve.co.uk. The firm has up to eight weeks to reach a final answer, after which the Financial Ombudsman Service will look at the case. One caveat worth reading in the terms: the Ombudsman route is stated to cover the insurance, and not the features the documents describe as non-insured.

The renewal-price rule that protects your buildings policy stops short of this one

In January 2022 the Financial Conduct Authority stopped insurers charging existing customers more at renewal than an equivalent new customer would pay. Those rules sit in chapter 6B of the Insurance: Conduct of Business sourcebook, and the application rule is narrow. It says the chapter "applies where a firm carries out any of the following activities in relation to a home insurance or motor insurance policy or any related additional product sold to a consumer".

A standalone home emergency policy bought direct from HomeServe is not a home insurance policy, and it is not an additional product sold alongside one. On the plain reading of that rule the equivalent-new-business-price protection does not reach it, which is how a £6 first year and a £197.40 second year can sit on the same page without breaching anything. This is our reading of the application rule rather than a statement the regulator has made about this product, and it is worth confirming with HomeServe if the renewal is the part of the deal you care about.

The practical consequence is small but real: the discipline that stops your buildings insurer walking your price up year after year is not doing any work here, so the renewal figure is worth diarising rather than assuming.

A £30.6m fine in 2014, and the complaints book in 2026

On 13 February 2014 the Financial Conduct Authority fined HomeServe Membership Limited £30,647,400 — at the time one of the largest retail conduct penalties it had issued. The final notice covers January 2005 to October 2011 and describes mis-sold policies, unfair complaint handling between January 2010 and April 2011, and misleading telephone sales. Some 69,000 customers were mis-sold two insurance policies. The penalty would have been £43,782,058 without the 30% discount for early settlement, and about £12.9m of redress had been paid by the date of the notice against £16.8m expected. The regulator noted that a significant proportion of the customers affected were of retirement age.

Twelve years is a long time in a compliance department, and the more useful question is what the book looks like now. HomeServe publishes its own complaints return. For the six months from 1 January to 30 June 2026 it recorded 2,264 insurance complaints opened, a rate of 3.05 per 1,000 policies, with 53% closed inside three days, a further 46% closed within eight weeks, and 22% upheld.

That rate also gives a rough sense of the size of the UK book, which the group accounts do not break out: 2,264 complaints at 3.05 per 1,000 policies implies somewhere around 742,000 policies in force. That figure is arithmetic on the published rate, not a number HomeServe states, so treat it as an order of magnitude.

Where your water company fits in

Many people meet this policy through a utility bill rather than through HomeServe. The group's accounts for the year to 31 March 2023 record renewed relationships with three water partners covering 6.4 million households, and a three-year renewal with E.ON covering a further 5.0 million. Northumbrian Water and South West Water both carry the 50p offer on their own websites, described in Northumbrian's words as "50p a month in year one with £30 excess. New customers, homeowners only."

The arrangement is an introduction, not a sale by the water company. The contract is with HomeServe, the insurer is Aviva, and the water company's role ends at the link. Neither the Northumbrian Water nor the South West Water page states whether the utility is paid for making that introduction, and we could not establish it either way from a primary source — if that matters to you, it is a fair question to put to either company.

One eligibility point travels with the offer wherever it appears: it is for homeowners. Landlords are quoted on separate products, and the same is true of flats and of let or sub-let property, so read the restrictions on the product you are actually shown rather than the one you arrived from.

The jobs this policy will not send an engineer for

The exclusions are short, specific and worth reading before the first cold snap. The policy does not cover a boiler breakdown that leaves you without heating or hot water; that is a different and dearer HomeServe plan. It does not cover guttering. It does not cover soakaways. It does not cover shared drains, or drains and pipes you are not responsible for. And it does not cover mixer or digital showers, which between them account for most showers fitted in British homes in the last twenty years.

The terms add a second layer. Pre-existing faults are out. Removing sludge, scale or rust is out. A frozen pipe that has not actually leaked is out. And a system that has not been serviced in line with the relevant British Standards can be declined on that basis alone, which is a condition the reader controls and should keep paperwork for.

Nothing in that list is unusual for home emergency cover. The point is the shape of what remains: a policy for water escaping, water not draining and taps that have stopped working, sold at a price that assumes most people will not need it in any given year.
