Home Maintenance Budget UK: How Much to Set Aside

There is no official figure for what a home costs to keep up, only rules of thumb that give very different answers for the same house. This guide explains them, then builds a yearly budget from the jobs a real home needs, with a worked example for a three-bedroom semi you can copy.

There is no official figure for how much to spend keeping a home in good repair. The rule of thumb you will see most is 1% of the home's value a year, with some versions going up to 4% for older homes or homes in poor condition. On an average semi-detached house in England, worth £292,000 in July 2026, 1% is £2,920 a year.

That number is a starting point, not an answer. It knows the price of your house and nothing about the house itself. A better figure comes from listing what your own home needs, how often and what each job costs, then spreading the big, irregular jobs over their likely life. Done that way for an illustrative three-bedroom semi, it comes to about £2,460 a year, or £205 a month, before anything genuinely unexpected.

This guide shows the working, so you can swap in your own numbers.

The short version

No official body sets a home maintenance budget; the 1% of value rule and the £1 per square foot rule are rules of thumb.
The two rules give very different answers for the same house: about £2,920 and about £970 a year for a typical semi.
A budget built from your own home's jobs is more reliable: routine servicing, cleaning and decorating, a repairs pot and funds for the big items.
Our illustrative three-bedroom semi comes to about £2,460 a year, or roughly £205 a month.
Age, construction, condition, trees and off-mains heating or drainage all push the figure up.
In a leasehold flat much of the outside upkeep comes through the service charge and any reserve fund, so your own pot mainly covers the inside.
What you actually spent last year is the best guide to next year, so write it down as you go.

The rules of thumb for a home maintenance budget

Two rules turn up again and again in UK guides, including HomeServe's guide to saving for repairs:

The 1% rule. Set aside about 1% of your home's value each year. Some versions stretch it to a range of 1% to 4%, with the top end for older homes or buildings in poor condition.
The square foot rule. Set aside about £1 for every square foot of floor area each year, which is roughly £10.76 a square metre.

Here is what they give for the same illustrative semi:

Rule	Working	A year
1% of value	1% of £292,000	£2,920
4% of value	4% of £292,000	£11,680
£1 per square foot	90 m² is about 969 sq ft	£969

The £292,000 is the average price of a semi-detached house in England in July 2026, from the UK House Price Index. The 90 m² floor area is our assumption; your EPC shows your own.

Where the rules fall down

They price the location, not the building. The same semi has the same gutters in Sunderland and in Surrey, but the 1% rule gives the dearer one a much bigger budget.
They ignore age and construction. A 1990s brick semi and a Victorian semi with a slate roof and timber sash windows can share a value and a floor area.
They smooth out lumpy costs. Most years you will spend less than the rule says. Then a boiler goes and you spend more than the year's figure in one week.
They do not know what is due. A roof replaced last year and a roof on borrowed time look the same to a percentage.
In a flat they double count. Much of the building's upkeep already comes through the service charge.

Use them as a sense check on your own figure, not as the figure.

A better method: build it from your home's own jobs

List the routine jobs and how often they come round. The UK home maintenance checklist has the usual intervals: the boiler service yearly, gutters twice a year, the chimney once or twice depending on fuel, the electrics every ten years.
Price each one. Use last year's invoice if you have it, a quote or a published cost guide. Note which you used.
Turn each into a yearly figure. A job every five years costing £1,300 is £260 a year.
Add a fund for each big item with a working life. Find out roughly how old it is, then divide the replacement cost by its expected life. How long home appliances last covers the usual lifespans and the signs a boiler is near the end.
Add a rainy day pot for what no schedule predicts: a blocked drain, a fence blown down, a pump that fails.
Check it against what you actually spent at the end of the year and adjust.

Worked example: an illustrative three-bedroom semi

This example is illustrative, not a quote. The house is a three-bedroom semi of about 90 m² with a gas combi boiler, uPVC windows, a pitched tiled roof and a wood burner used most winter evenings. Every cost is either a published figure, named and dated, or our assumption, marked as one.

Item	How often	Cost each time	A year	Source
Boiler service	Every year	£100	£100	Checkatrade, Mar 2026
Gutters cleared	Twice a year	£125	£250	Checkatrade, Sep 2026
Chimney swept	Twice a year (wood)	£90	£180	Checkatrade, Sep 2026
Outside painting	Every 5 years (assumed)	£1,300	£260	Checkatrade, Sep 2026
Inside decorating	One room a year (assumed)	£450	£450	Checkatrade, Sep 2026
Electrical inspection	Every 10 years	£200	£20	Checkatrade
Roof and chimney repairs	As needed	Varies	£250	Assumption
Boiler replacement fund	About every 12 years (assumed)	£3,847	£320	BCIS for HomeServe, Sep 2025
Windows replacement fund	About every 30 years (assumed)	£6,920	£230	FMB, Jan 2026
Rainy day pot	As needed	Varies	£400	Assumption
Total			£2,460

That is £205 a month. Notes on the figures:

Gutters. Checkatrade gives £100 to £150 a visit for a medium semi; we used the middle. Its regional data runs from about £103 a job in the North West to £169 in Greater London.
Chimney. Checkatrade's average sweep is £90. HETAS advises sweeping at least twice a year when burning wood and once for smokeless fuel. No fire in use? Leave the line out.
Decorating. Checkatrade puts a medium room at £450 and outside painting for a three-bedroom semi at £1,100 to £1,500. How often is our assumption: exposure, finish and how much you do yourself all change it.
Electrics. An inspection every ten years is Electrical Safety First's recommendation for a home you live in; Checkatrade gives an average cost of £200.
Boiler fund. Energy Saving Trust gives an average boiler life of 10 to 15 years; we used 12. The £3,847 supply-and-fit figure is BCIS research published by HomeServe, including VAT. Checkatrade's split, about £1,500 for a combi boiler plus £1,000 to £2,000 to fit it (March 2026), lands in the same area.
Windows fund. Published guides disagree widely. The Federation of Master Builders' HomePicks puts uPVC double glazing for a three-bedroom house at £5,130 to £8,710 (we used the middle); other guides quote more. There is no reliable published lifespan, so the 30 years is an assumption.
Roof and rainy day pots. Both are assumptions. For scale, BCIS research for HomeServe puts jetting external drains at about £259 and replacing a seized boiler pump at £471. Checkatrade puts small repairs to a tiled roof at £90 to £160 per m² before VAT and access equipment.

How it compares

£2,460 sits between the two rules of thumb for the same house: well above the £969 the square foot rule gives and below the £2,920 of the 1% rule. Take out the two replacement funds and the routine running cost is about £1,910 a year; the funds are what stop a dead boiler becoming a crisis.

There is no roof replacement fund here because nothing suggested the roof was near the end. If your survey says otherwise, add one: Checkatrade's average for a new roof is £8,000, with a gable roof at £7,000 to £16,250 before VAT (March 2026).

What pushes the figure up or down

Age. Older homes have more original parts reaching the end of their lives at once. They also have more that needs a specialist: lime mortar, timber sash windows, slate.
Construction. Render needs repainting and timber cladding needs treating. Checkatrade notes that older flat roofs are prone to leaks, while pitched roofs generally last longer.
Condition. What the last survey found and what the previous owner put off.
Heating and drainage off the mains. An oil boiler adds tank checks to the yearly service. In England a septic tank or small treatment plant must be emptied at least once a year, or as the manufacturer says, by a registered waste carrier.
Trees and exposure. Gutters under trees need clearing more than twice a year; homes on the coast or a hilltop get through paint and pointing faster.
Listed buildings and conservation areas. Like-for-like materials and the need for consent can make the same repair dearer and slower.
Size. More roof, more gutter and more wall to paint.
Doing it yourself. Decorating, bleeding radiators and clearing gully grates cost little but time. Gas, electrics, roofs and anything up a ladder above the ground floor are jobs for a professional, so budget for them as paid work.

Flats: service charges and the reserve fund

Most flats in England and Wales are leasehold. The freeholder or a management company usually looks after the roof, the outside walls and the shared parts. You pay your share through the service charge.

Many leases also provide for a reserve fund (sometimes called a sinking fund): regular contributions saved towards big future works such as a new roof or a lift. The Leasehold Advisory Service, LEASE, sets out how they work:

There is one only if the lease provides for it.
Contributions must be reasonable and can be challenged like any other service charge.
A private landlord must hold service charge money on trust in a separate account.
When you sell, you do not normally get your contributions back; they stay with the building.
Paying from the fund does not remove the duty to consult: major works costing any one leaseholder more than £250 still need section 20 consultation.

So a flat owner's budget has three parts:

The service charge itself, as a fixed line, with a cushion for a balancing charge where the lease lets the landlord collect on estimates and the year's costs come in higher.
The inside of your flat: the boiler service, decorating, appliances and, if the lease makes them yours, the windows.
A cushion for major works, sized once you have seen the building's accounts, the reserve fund balance and any planned works.

An empty reserve fund in a building with an old roof is the warning sign. Service charges and ground rent explained covers your right to see the accounts and what to ask before you buy.

In Scotland flats are owned outright. The title deeds, or the Tenement Management Scheme where the deeds are silent, decide how owners share the cost of the roof, the outside walls and the other common parts, often in equal shares.

A sinking fund for your own home

The same idea works for a house. Put the yearly figure aside monthly in its own account and let the big jobs draw on it.

Pay in on payday. A standing order of the monthly figure, £205 in the example, means nobody has to decide each month.
Keep it separate from everyday money. A pot that sits in the current account quietly becomes the holiday.
Pay the routine jobs from it as they come round and let the boiler and window funds build.
Expect it to run short early on. A boiler fund at £320 a year holds £960 after three years, not £3,847. That gap is why a separate emergency cushion matters; MoneyHelper's guide to emergency savings explains how to size one.
Top it up after a big spend rather than starting again from nothing.

Whether you also take out boiler cover, or lean on your buildings insurance, is a separate question. Buildings insurance is generally there for sudden events such as a storm or an escape of water rather than wear and tear, so read what your own policy covers before relying on it.

What to keep, so next year's figure is real

The best guide to next year's budget is what you actually spent this year. That only works if you write it down as it happens.

For every job, keep:

the date and what was done
who did it, with their contact details
what it cost, with the invoice or receipt
any certificate or guarantee that came with it
for anything big, a photo of the finished work

At the end of the year, add it up and set it against the budget. Two or three years in, you will know what your house really costs to keep up, which no rule of thumb can tell you. The same records pay off again when you sell: buyers and their conveyancers ask how old the boiler is and what has been done to the roof. The house selling checklist covers what to gather. Keep each boiler service record too: most boiler warranties depend on them, as what a boiler service includes explains.

Common questions

How much should I budget for home maintenance in the UK?

There is no official figure. The most common rule of thumb is 1% of the home's value a year, with some versions suggesting up to 4% for older homes or homes in poor condition. A more reliable figure comes from pricing your own home's routine jobs, adding funds for big items such as the boiler and windows and keeping a pot for surprises. For an illustrative three-bedroom semi that came to about £2,460 a year.

What is the 1% rule for home maintenance?

It is a rule of thumb that says to set aside about 1% of your home's value each year for maintenance and repairs, so £2,920 for a £292,000 house. It is quick but crude: it reflects where the house is rather than what it is, ignores age and construction and says nothing about which big jobs are due. Use it as a sense check against a budget built from your own home's jobs.

How much should I save each month for home repairs?

Work out a yearly figure and divide it by twelve. In our worked example for a three-bedroom semi, about £2,460 a year comes to roughly £205 a month, covering routine servicing, gutters, decorating, a repairs pot and funds towards a new boiler and windows. A standing order into a separate account on payday is the simplest way to keep it going.

What are typical annual home maintenance costs in the UK?

It depends on the house, but the routine jobs are fairly predictable. Checkatrade puts a gas boiler service at £80 to £120, gutter clearing at £100 to £150 a visit for a medium semi and a chimney sweep at about £90, in 2026 cost guides. The big costs are the irregular ones, such as a replacement boiler, which BCIS research for HomeServe put at about £3,847 including fitting and VAT.

Do I need a maintenance budget if I own a flat?

Yes, but a smaller one for your own flat. In a leasehold flat the freeholder usually looks after the roof, outside walls and shared parts and you pay through the service charge, which may include contributions to a reserve fund. Your own budget then covers the inside of the flat, the boiler, appliances and possibly the windows, plus a cushion for balancing charges and major works.

What is a sinking fund for home maintenance?

It is money set aside regularly for a known future cost, so the cost arrives already paid for. In a block of flats it usually means the reserve fund the lease provides for. For a house it means saving towards things like a new boiler or windows by dividing the replacement cost by the item's expected life and putting that amount aside each year.

How long does a boiler last and what does a replacement cost?

Energy Saving Trust gives an average boiler life of 10 to 15 years. BCIS research published by HomeServe in September 2025 put a boiler replacement at about £3,847 including fitting and VAT. Checkatrade gives about £1,500 for a combi boiler plus £1,000 to £2,000 to fit it. Saving towards it over the boiler's life spreads the cost.
