Keeping your home’s heating and plumbing systems in top shape isn’t just a matter of convenience—it’s essential for safety, efficiency, and long-term cost savings.
With colder months always just around the corner in the UK, homeowners should ensure their systems are ready to perform when needed most.
This annual home maintenance checklist is designed to help you stay on top of essential tasks like boiler servicing, pipe inspections, and radiator upkeep.
Whether you’re a homeowner or a landlord, following this list can help prevent costly emergencies and improve energy efficiency throughout your property.
1. Book Your Annual Boiler Servicing
Your boiler is the heart of your home’s heating system. Annual boiler servicing by a Gas Safe registered engineer is crucial to ensure it’s operating safely and efficiently.
During a service, the engineer will check for carbon monoxide leaks, test components, clean internal parts, and ensure everything is working as it should.
A well-maintained boiler lasts longer, runs more efficiently, and reduces the risk of sudden breakdowns in winter.

2. Bleed and Balance Radiators
If your radiators have cold spots or take a long time to heat up, they may need bleeding. Air can become trapped inside your heating system over time, reducing efficiency.
You can use a radiator key to release trapped air. After bleeding, it’s a good idea to balance your radiators to ensure even heat distribution throughout your home. This helps your boiler work more efficiently and can reduce energy costs.
3. Check Pipe Insulation
Frozen pipes are a major issue during winter. Check that all exposed pipework—especially in lofts, garages, and external walls—is well insulated.
Pipe insulation is inexpensive and easy to install. It helps prevent freezing and bursting during sub-zero temperatures and supports better heating system performance.
4. Test Your Thermostat and Heating Controls
Make sure your thermostat, timer, and heating controls are functioning correctly. A faulty thermostat can lead to inconsistent temperatures and wasted energy.
Smart thermostats are a great upgrade that offer better energy control and can help reduce heating bills. Consider installing one during your next boiler servicing appointment.
5. Inspect Taps, Toilets, and Sinks
Leaky taps and slow-draining sinks are common signs of underlying plumbing issues. Over time, even a small leak can waste litres of water and increase your bills.
Check under sinks for signs of damp, water damage, or corrosion. Toilets that continuously run may need new flush valves or seals—both affordable repairs that prevent bigger problems down the line.
6. Clear Out Drains and Gutters
Don’t forget the importance of external maintenance. Leaves and debris in gutters can lead to blockages, which might cause water to overflow and damage your property.
Likewise, slow or blocked indoor drains could be signs of a build-up that needs professional cleaning. Keeping drains clear helps prevent unpleasant odours and pipe damage.
7. Flush Your Heating System
Over time, sludge and debris can build up in your heating system, reducing efficiency and causing cold spots in radiators. Flushing your system helps to clean out this build-up.
This doesn’t need to be done annually, but it’s worth discussing with your engineer during your boiler servicing appointment—especially if your system is several years old or you’ve noticed heating issues.
8. Test Water Pressure
Low water pressure in your taps or shower can indicate a problem with your plumbing system. Conversely, high pressure can damage pipes and appliances.
Most UK homes should have a water pressure between 1–2 bar. You can check this using a pressure gauge or ask your heating engineer to review it during your annual boiler servicing visit.
9. Check for Hidden Leaks
Hidden leaks behind walls or under floorboards can be difficult to spot until significant damage is done. Look for telltale signs such as damp patches, mould, or unexplained increases in your water bill.
If you suspect a leak, call a professional plumber to inspect your system. Early detection can save thousands in repair costs.
10. Keep a Maintenance Record
Lastly, keep a record of all maintenance checks, repairs, and boiler servicing visits. This is especially useful when selling your home or managing a rental property. It also ensures you don’t miss important dates and helps identify recurring issues.
