10 Things Every New Homeowner Should Check Before Moving In

Buying a new home is exciting… until you realise half the things you assumed were “fine” turn out to be not-so-fine once you’re actually living there.

Most people focus on the big stuff - location, room sizes, garden, parking - but it’s the hidden plumbing, heating and electrical details that have the biggest impact on everyday comfort (and your wallet).

So before you start painting walls and ordering furniture, here are 10 essential checks every new homeowner should make to avoid surprises, unexpected costs and unnecessary stress later on.

1. Check the Age and Condition of the Boiler

A boiler is one of the most expensive appliances in your home, and yet it’s the thing most new buyers forget to ask about. A great-looking house means nothing if the boiler sounds like it’s preparing for take-off.

Ask for:

• The age of the boiler

• The last service date

• Any repair history

• Whether it still has a warranty

Older boilers can still run well, but anything over 12–15 years will likely be approaching the end of its lifespan. A quick check now can save you a winter filled with cold showers and emergency call-outs.

2. Test the Water Pressure (Don’t Skip This!)

Low water pressure might sound like a minor issue… until you try to shower in it. Slow-filling baths, weak taps, inconsistent heating - all signs that something’s not right.

Run taps, flush toilets, and turn the shower on. If the pressure is noticeably low, it could be due to:

• Partially blocked pipes

• A failing pump

• Issues with the mains supply

• Limescale build-up

It’s a simple check that tells you a lot about the health of the home’s plumbing.

3. Look for Signs of Slow or Blocked Drains

Before you move in, check how quickly sinks, showers, and baths drain. Slow drainage can point to deeper blockages or pipes lined with years of grease, hair or debris.

This is one of those problems that seems small at first… until you’ve got a sink full of murky water after brushing your teeth.

4. Inspect the Radiators - Especially the Cold Spots

Radiators are easy to overlook, but they tell you a lot about a home’s heating system. Turn them on and feel for:

• Cold spots (usually sludge build-up)

• Uneven heating

• Strange noises

• Radiators that take forever to warm up

These are common signs the system needs a power flush or balancing - nothing dramatic, but worth knowing before you move your entire life in.

5. Check the Consumer Unit (Fuse Board)

The fuse board is the heart of the electrical system. Older, outdated units can’t support modern appliance-heavy lifestyles and may not meet current UK safety standards.

Look for:

• RCD protection

• Labels that make sense

• Signs of damage or tampering

• Whether it looks decades old

If you're unsure what you're looking at, that’s completely normal - but if it looks like it belongs in a museum, it’s probably time for an upgrade.

6. Test Every Socket and Light Switch

It takes five minutes, and it’s worth it. Switch everything on and off. Plug a phone charger into every socket.

Common signs of issues include:

• Flickering lights

• Buzzing switches

• Sockets that don’t work

• Overheating outlets

These things are much easier (and cheaper!) to fix before the rooms are filled with furniture.

7. Check for Leaks… in the Places No One Looks

Leaks don’t always show up as obvious puddles. Sometimes they hide under sinks, behind toilets, around radiators, or near the boiler.

Look for:

• Damp smells

• Discolouration on walls or ceilings

• Mould patches

• Soft or warped flooring

A tiny drip can turn into a big bill - especially once you move in and start using everything daily.

8. Find Out the Age of Pipes and Plumbing Materials

Not all pipes are created equal. Older homes might still have:

• Old copper pipes with corrosion

• Plastic pipes from early generations that degrade over time

• Lead pipes (rare, but still found in older builds)

Newer homes tend to have more modern, efficient materials. Knowing what you’ve got helps you plan future upgrades and avoid unexpected failures.

9. Locate All the Important Shut-Off Points

Before you even unpack a box, you should know where to find:

• The main water stop tap

• Boiler isolation valves

• Gas shut-off valve

• Fuse board

• Thermostat

• Outside drains

Because when something goes wrong - and it always does at some point - you don’t want to be sprinting around the house like you’re on an episode of Crystal Maze.

10. Review Any Service History, Paperwork and Compliance Certificates

This is the part most people skip… and regret later.

Request or check for:

• Electrical Installation Condition Reports (EICR)

• Boiler service records

• Gas Safety Certificates (for rented homes)

• Any plumbing or electrical work invoices

• Guarantees or warranties

This paperwork gives you a clear picture of what’s been done, what’s been maintained, and what might need attention.

Final Thoughts

Moving into a new home should feel exciting, not stressful. By checking these areas early, you get ahead of potential issues and avoid those “unexpected” costs that always seem to pop up at the worst possible time.

The best part? You don’t need specialist skills to spot most of these red flags - just a careful eye and a little patience.

And if anything doesn’t look quite right, having a trusted professional take a quick look can give you peace of mind before you settle in.
