How much does house maintenance cost per year in the UK

UK households spend about £620 a year (£11.90 a week) on maintenance and repair of the dwelling, and £1,664 a year (£32.00 a week) on alterations and improvements to that same home (ONS, Family spending workbook 1 and workbook 5, financial year ending 2025). Both are measured averages across all UK households, renters and new-builds included. Neither is a budget for your house. Your number is each system’s replacement price divided by the years that system lasts, added up: the averages describe a population, the arithmetic describes a building.

What the £620 is a measurement of

The £11.90 is what households were recorded paying out, not what their houses needed. Family Spending is a survey of expenditure. It counts money that left the account under the heading “maintenance and repair of dwelling”, so a house whose owner spent nothing last year enters the average as a low figure rather than as a deferral.

Inside the weekly total sit four lines: house maintenance and similar at £7.80, paint, wallpaper and timber at £1.50, central heating repairs at £1.40, and equipment hire and small materials at £1.30. Those add to £12.00 against a parent figure ONS rounds to £11.90. ONS puts the whole line at 1% of a household’s total expenditure and 5% of what it spends on housing.

Two features of that average matter more than its size. It covers every UK household, so renters, whose maintenance is a landlord’s cost, are averaged in alongside owners, and a house finished last year is averaged in alongside a 1930s semi with its original roof; ONS publishes no tenure split on this line that would place an older owner-occupied house against the average. The four-year series is the second feature: £9.70, £10.70, £11.00, £11.90, in cash terms. That is a rise in pounds paid, not evidence that houses have started consuming more.

Improvements take 2.7 times as much as maintenance

Alterations and improvements to the dwelling run at £32.00 a week against maintenance and repair’s £11.90, which is 2.7 times as much, in the same ONS table for the same year. As a share of spending, improvements take 3% of the household total and 14% of housing; maintenance takes 1% and 5%.

That ratio is not a verdict on anyone’s judgement. The two spends have different shapes. An improvement is chosen, dated, visible when it is finished, and enjoyed daily: you decide to do the kitchen and then you have a kitchen. Maintenance is scheduled by the component rather than by you, invisible once it is done, and conspicuous only when it is skipped. A new worktop is in the estate agent’s photographs. A replaced roof underlay is not in any photograph anyone will look at.

The two therefore compete for one pot of money and only one of them ever asks. That is the structural reason a house can be improved and neglected at the same time, and why a household that has spent well above the average on its home may have spent none of it on the clocks.

Where the deferred money turns up

In England, 3.5 million households (14%) live in a home that fails the Decent Homes Standard (English Housing Survey 2022 to 2023, housing quality and condition). The same survey counts 2.1 million households (9%) living with at least one Category 1 hazard and 1.0 million (4%) with damp; both are counts across all English households, not subsets of the non-decent group.

The same survey prices the way back. Bringing a non-decent home up to the Standard cost £9,266 on average, with a median of £7,953, at 2022-23 prices. Those figures cover England. The spending figures above cover the whole UK, so the two datasets are not two halves of one picture and cannot be added together.

What a backlog measures is the distance between a component’s clock and a household’s attention. Deferring maintenance does not save the money, it moves it, and it moves it into a larger number, because a defect left in place keeps working on the material around it. Fixing the cause later stops the damage. It does not undo it. The two-inflection curve is the shape behind that: slow degradation to about half of rated life, steeper to three-quarters, then a cliff, which is why the last deferred years cost the most.

Your house’s annual cost is arithmetic

The annual cost of your house is each system’s replacement price divided by the years that system lasts, added together. That is the annual-cost method applied to a whole building instead of to one decision.

A house is roughly 22 systems on separate clocks running from about 10 years to 200 (the full map, part by part). A smoke detector runs a fixed ten-year cycle. Load-bearing masonry runs one or two centuries and never enters a homeowner’s budget. Most of what an owner has to fund sits under 40 years, which means most of it lands at least once during an ownership.

Work through it in this order.

1. List the systems your house has. Roof covering, gutters and downpipes, windows, boiler, radiators and pipework, consumer unit and wiring, extract fans, wet-room membrane, floor finishes, external decoration.
2. Date each one. The survey you had at purchase, the boiler’s service record, the electrical installation condition report and the previous owner’s paperwork carry most of the dates between them. Where the paperwork is missing, a building inspector can date the systems in one visit.
3. Get a replacement price for each. Your own quotes are the right source: a national band has not seen your roof, and a quote has. This is a handful of quote requests, so start with the two or three biggest systems; with the roof, the boiler and the windows priced, most of the total is already on the page.
4. Divide each price by the full life of the new component, not by the years the old one has left. You are pricing the next cycle, not the remains of this one.
5. Add the results. Use the VAT-inclusive figure, the number that leaves your account, on both sides of every division.

The total is your annual cost. If it lands well above £620, nothing has gone wrong: the average includes the renters and the new-builds your house is not.

The 1% rule prices the house, not what wears out

The percentage’s input is the problem: a house’s price carries its land and its location, and neither of those wears out. You will meet the rule as advice to set aside one per cent of the house’s value every year. It is folklore rather than a measured figure, and no UK statistics office publishes one.

Its appeal is that it needs one input you already know. The growth in a house’s price is mostly its land, which is where the gain in owning one comes from and is not a thing that degrades. Two houses on the same street at the same price carry the same one per cent, and if one had its boiler and roof replaced in the last decade and the other did not, they have different years coming.

Where a percentage is useful is afterwards, as a sanity check on a figure you already built per system. If your arithmetic lands somewhere far away from it, that is a prompt to re-check a lifespan or a quote, not a reason to swap the arithmetic for the rule.

Turning a number into a budget

Set the annual figure aside monthly and keep the calendar separately, because the total is an average of a spend that is not level. Nothing happens in year three. Year seven has a boiler and a wet-room membrane in it.

That leaves a choice, and it is not “save up or don’t”. You can level the payments into a separate account and let the fund carry the heavy years, which costs you the discipline and nothing else. You can hold the calendar without the fund and borrow or delay when a year is heavy, which costs interest, or costs the extra work the delay adds. Or, where the money is not there, you take the components as they fail, which is the mode the backlog above is made of; that is still a decision, and it can be priced and staged rather than arriving. What the two modes cost each other is the subject of the corrective and planned comparison.

Whichever you pick, the calendar is the part that has to survive the whole ownership, which is why you keep each system with its own date and its own next cost in appkeep: the year the roof needs pricing shows up before it shows up on the roof. Where one component is already in question this year, the repair-or-replace calculator runs the same division on a single decision.

Worked example: Owen in Leeds

Owen has a 1936 semi in Leeds and has owned it for eleven years. He wants one number for next year’s budget.

He starts where the search results start, with the average: £11.90 a week is £619 a year, call it £620. Then he reads the line above it in the same table, £1,664 a year on alterations and improvements, and recognises his own eleven years in the second line rather than the first. The kitchen and the downstairs cloakroom were improvements. Nothing he has paid for replaced something that had reached the end of its life.

The backlog figure settles it. Bringing an English home that has fallen below the Decent Homes Standard back up to it cost £9,266 on average in 2022-23. The prices are older and the measure is different from the UK-wide spending average, but Owen’s house is in England and the scale carries: deferral accumulates into a bill many times the yearly average, arriving on a schedule he did not set.

So he does the arithmetic. The survey from purchase and the service records date most of his systems. The newest quote in the drawer prices a replacement boiler at £2,900 installed; a new one is rated for fifteen years, so that line of his list reads £2,900 ÷ 15 = £193 a year. His number, from his quote, for his house. The rest of the list fills the same way. The roof line matters most: the arithmetic puts it in a named year, early enough to gather three quotes in a quiet month instead of one in February with water coming in.
