Repair or replace: your go-to guide

Repair or Replace? A UK Homeowner’s Essential Guide to Home Repairs

When things go wrong in your home—whether it's the boiler breaking down or the roof springing a leak—the question always comes up: Should I repair it or replace it? This guide is designed specifically for UK homeowners and landlords, helping you make informed, cost-effective decisions on essential household systems and appliances.

🔍 Key Questions Before You Decide

• How old is the item? Most systems have a predictable lifespan. If it's near the end, repairs may only buy limited time.

• What’s the cost of repair vs. replacement? If the repair costs over 50% of the replacement, it's often better to upgrade.

• Is it covered by a warranty or home cover plan? Check boiler cover, appliance warranties, or insurance policies.

• Is it energy efficient? Older units can cost more to run. Newer models often pay for themselves in energy savings.

• Is it a repeat issue? If you’re calling out engineers often, replacement could save you in the long term.

📋 Budgeting for Home Maintenance

A smart strategy is to set aside around 1% of your home's value annually for home maintenance. If your home is worth £250,000, that’s about £2,500 per year for repairs, upgrades, or emergencies. Also consider taking out home emergency cover with companies like British Gas, HomeServe, or your current energy provider to protect key systems like your boiler, plumbing, and electrics.

🏁 Final Word: Think Long-Term

Sometimes, repair feels easier in the short term—but replacement is often cheaper and safer in the long run. Evaluate the total cost, potential energy savings, and peace of mind that comes with newer, more reliable systems. If in doubt, always consult a Gas Safe registered engineer, Part P-certified electrician, or Trustmark-approved tradesperson to assess your options.
