First-Time Buyers: 5 Hidden Home Maintenance Costs You Haven't Budgeted For

Buying your first home is a huge milestone. There is the mortgage, deposit, solicitor’s fees, removals and all the furniture you suddenly need.

Then comes the first dripping tap.

Unlike renting, there is no landlord or letting agent to call when the boiler starts making strange noises or rainwater pours over a blocked gutter. The responsibility is yours. So are the costs.

Many first-time buyers budget carefully for their monthly mortgage and household bills, but forget about residential property maintenance. The smaller jobs can soon add up. More importantly, a minor issue can become an expensive repair if it is ignored.

Here are five commonly overlooked costs to include in your first-year home budget.

1. Boiler servicing and heating repairs

A boiler service is one of those costs that is easy to forget, particularly if the boiler appeared to be working when you moved in.

It is still worth arranging an annual service. A service can identify faults early, check that the appliance is operating safely and help maintain the terms of some manufacturer warranties.

For a typical UK home, budget around £80–£150 for a boiler service, depending on your location and the appliance. Always use a Gas Safe registered engineer for gas appliances, pipework and flues. You can check an engineer through the official Gas Safe Register.

The service is the predictable part. The surprise comes when a component fails.

A faulty pump, valve or thermostat may cost a few hundred pounds to repair. A very old boiler may eventually need replacing altogether. That is a much bigger expense, often running into thousands.

What to do when you move in

Ask the seller or estate agent:

• When was the boiler last serviced?

• How old is it?

• Is there a warranty or service plan?

• Are the manuals and previous service records available?

• Does the heating system work consistently throughout the property?

Put the service date in your calendar. It is a small annual cost compared with losing heating during a cold January.

2. Guttering, roofline and exterior maintenance

You may not notice the gutters when viewing a property. They sit above eye level and are often out of sight from the front door.

That does not mean they can be forgotten.

Leaves, moss and debris can block gutters and downpipes. Water then overflows onto brickwork, window frames and external walls. Over time, this can contribute to damp, staining and deterioration.

A typical gutter clean and inspection may cost around £80–£200 for a small house. Minor repairs, such as replacing a joint, securing a downpipe or repairing a section of guttering, can increase the bill.

You may also discover loose roof tiles, damaged flashing or cracked pointing. These are not always urgent, but they should not be ignored. Water ingress rarely improves by itself.

Arrange an exterior check during your first year, especially before autumn and winter. You can read more about the practical difference between small repairs and specialist work in our guide to what local handyman services can usually do.

Never climb onto a roof or use an unstable ladder to save a few pounds. A professional inspection is safer and may identify issues you would miss from ground level.

3. Damp investigations and moisture-related repairs

Damp is one of the costs first-time buyers often discover after moving in.

A property may look fine during a quick viewing, particularly if furniture is covering an affected wall or the room has recently been redecorated. Problems may become more obvious once the heating is on, furniture is moved or heavy rain arrives.

Look out for:

• Musty smells

• Peeling wallpaper or paint

• Bubbling plaster

• Mould around windows

• White salts on walls

• Damp skirting boards

• Water staining on ceilings

• Mould returning after cleaning

An independent damp survey for a typical two- to four-bedroom home may cost around £200–£400 plus VAT. Smaller flats may cost less, while larger, older or period properties may cost more. The Checkatrade guide to damp survey costs provides a useful overview of the factors involved.

A survey is not the same as a free quote visit from a damp-proofing company. A free visit may be useful, but it can also be linked to a recommendation for that company’s own treatment. If the cause is unclear, consider obtaining an independent assessment before agreeing to major work.

The repair itself could be as simple as improving ventilation or fixing a leaking gutter. It could also involve plumbing, roofing, external pointing or more substantial building work.

Do not simply paint over a recurring damp patch. Find the source first.

4. The garden and outside space

The garden can feel like a bonus when you first view a home. Then you arrive with the keys and realise the lawn is waist-high, the hedge is overgrown and the shed is full of somebody else’s belongings.

A basic tidy-up may cost around £60–£150 for a small, manageable garden. A more involved clearance, including hedge cutting, pruning and green-waste removal, can reach £150–£300 or more.

There may also be immediate equipment costs:

• Lawnmower

• Strimmer

• Secateurs

• Hose and fittings

• Outdoor storage

• Compost and soil

• Fencing materials

• Waste collection or skip hire

If you enjoy gardening, you can spread these costs over time. If the garden is overgrown or you are short on time, paying for a one-off tidy-up may be more practical.

Do not forget ongoing maintenance. A garden needs regular mowing, weeding, pruning and checks for damaged fencing or gates. Even a modest monthly allowance can prevent the outside space becoming another major project.

If several outdoor tasks need attention, group them together. This can be more efficient than booking separate visits for every small repair.

5. Emergency call-outs

The final hidden cost is the one you hope never to use: emergency repairs.

A burst pipe, serious leak, failed heating system or electrical fault can happen at any time. Unfortunately, problems rarely choose a convenient weekday morning.

A daytime emergency plumber call-out may be around £75–£150, often covering the initial visit or first hour. Evening, weekend and bank holiday visits can rise to £120–£300 or more, before parts and additional labour.

A small leak may be resolved quickly. A hidden leak under flooring or behind a wall can cost substantially more once damage, drying and reinstatement are included.

Keep a list of useful information in your home maintenance file:

• Stopcock location

• Fuse box location

• Boiler details

• Gas and electricity supplier

• Insurance policy information

• Trusted local tradespeople

• Emergency contact numbers

If you smell gas in Great Britain, leave the property if necessary and call the National Gas Emergency Service on 0800 111 999. For exposed wiring, flooding or serious structural damage, prioritise safety and contact the appropriate qualified professional.

How much should you budget for the first year?

A commonly used starting point is to set aside around 1% of your property’s value each year for maintenance. On a £250,000 home, that is approximately £2,500.

That is not a guaranteed bill. Some years will be quiet. Other years may include a boiler repair, damp treatment or urgent plumbing work.

For your first year, consider dividing your budget into two pots:

Planned maintenance

Allow for:

• Boiler servicing

• Gutter cleaning

• Garden work

• Small repairs and replacement parts

• Damp investigation if concerns arise

Emergency reserve

Keep a separate reserve of at least £1,000–£2,000 if possible. Older properties, ageing boilers and homes with survey concerns may justify a larger buffer.

The most important point is not to spend the entire maintenance budget on decorating and furniture. Keep something back for the unglamorous jobs that protect the building.

Use the right person for the job

Some jobs are suitable for capable DIY. Others are not.

A handyman may be able to help with small decorating jobs, minor carpentry, resealing, fixtures, fittings, accessible guttering and general residential property maintenance. Grouping several small jobs together can save time and make the cost easier to manage.

Gas work, complex electrics, structural alterations, serious damp and specialist roofing require the right qualified professional.

Before booking, ask whether the price includes materials, waste removal, access equipment and any call-out fee. Request a clear quote and check that the professional has suitable insurance and experience.

A simple first-year plan

During your first month, inspect the boiler, gutters, roofline, plumbing, windows and garden. Photograph existing defects and keep the survey handy.

Before autumn, arrange a gutter check and confirm that the heating works properly. During winter, monitor condensation, leaks and unusual boiler noises.

Keep a running list of small jobs. When the list grows, consider using reliable local handyman services for suitable repairs rather than allowing them to become more serious.
