What a strip-down boiler service is

A boiler service is a safety and performance check of your gas boiler. DPB carries out a full strip-down service: opening up the boiler, inspecting and cleaning the key internal components, checking the seals and flue, and testing that it's burning gas safely and efficiently. The price is £120–£180 including VAT.

It's for homeowners who want to keep their boiler running reliably, landlords who need their gas appliances kept safe, and anyone whose boiler manufacturer warranty depends on regular servicing.

Most manufacturers recommend a service every year. It's also worth booking if your boiler is making new noises, losing pressure, showing fault codes or taking longer to heat up.

Professional servicing matters because gas appliances must only be worked on by Gas Safe registered engineers, and because many problems, worn seals, blocked components, flue issues, can only be found by opening the boiler up.

What happens when a boiler isn't serviced

Skipping a service rarely causes an instant problem. That's why it's so easy to put off.

Small faults become breakdowns

Worn parts and build-up inside the boiler get worse over time until something fails: usually in winter.

Efficiency drops

A boiler that isn't burning cleanly uses more gas to do the same job.

Safety and warranty risks

Faulty gas appliances can be dangerous, and many manufacturer warranties require regular servicing.

Common mistakes we see

  • Waiting until the boiler breaks before booking a service.
  • Choosing a quick visual check instead of a proper service.
  • Letting a lapsed service invalidate a manufacturer warranty.
  • Using anyone who isn't Gas Safe registered.

What's included in a strip-down service

A proper service goes inside the boiler, not just around it.

Strip-down vs basic check

A basic check looks at the boiler running. A strip-down service opens it up so internal components can be inspected and cleaned, which is where many faults start.

Combustion and flue checks

The boiler's combustion is tested to confirm it's burning safely and efficiently, and the flue is checked to make sure fumes are being carried away properly.

Pressure and controls

System pressure, safety devices and controls are checked so the boiler responds as it should.

Brands we service

DPB is an approved installer for Ideal and Worcester. For servicing other makes, call Danny to check.

Landlords

Landlords need gas appliances kept safe for tenants. Call Danny to discuss servicing for rental properties.

After the service

If a part needs replacing, you'll get a clear explanation and price before any further work is done.

Getting the most from your boiler service

Book before winter

Booking a service in the warmer months means any problems are found and fixed before you rely on the heating every day. It's also easier to get an appointment that suits you.

Tell the engineer about any issues

Noises, pressure drops, fault codes, slow hot water or radiators that don't heat properly are all useful to mention. They help focus the service on what matters for your system.

Keep your paperwork

Keep a record of each service. It's useful for warranty claims, for landlords keeping safety records, and when you come to sell the house.

Signs your boiler needs attention between services

Pressure that keeps dropping, water around the boiler, a pilot light that keeps going out, unusual smells or new noises are all reasons to call. If you ever smell gas, leave the property and contact the National Gas Emergency number straight away.

What a service can't fix

A service keeps a boiler safe and efficient, but it can't make an old or undersized boiler new. If repairs are becoming frequent, Danny can advise on whether replacement makes more sense, see our boiler installation page.

Servicing and your heating system

Radiators that are cold in places or a noisy system can point to wider heating issues. These can be checked separately, see our central heating and radiators page.

Why a strip-down service is worth it

Opening up the boiler lets the engineer inspect and clean the parts where problems actually begin. That's the difference between a check that ticks a box and a service that keeps your boiler running.

Who services your boiler

Your service is carried out by DPB, Gas Safe registered under number 603724, with over 20 years in plumbing and heating. You deal with the same small team that installs boilers and heating systems, so advice is practical and based on what we see in homes across Wigan and Greater Manchester every week.

Combining a service with other work

If you have a dripping radiator valve, a cold radiator or a tap that needs attention, mention it when you book. Smaller jobs can often be looked at on the same visit, saving you a second appointment.

What you'll be told afterwards

At the end of the service, you'll be told what was checked, what was cleaned and whether anything needs attention. If a part is worn, you'll get a clear explanation and a price, and nothing extra goes ahead without your agreement.

Servicing older boilers

Older boilers benefit most from regular servicing, because worn parts are more likely. If a boiler is reaching the point where repairs no longer make sense, you'll get an honest opinion rather than repeated patch-ups.

Simple checks you can do

Between services, keep an eye on the pressure gauge, make sure the area around the boiler and flue is clear, and note any new noises or fault codes. These help the engineer when you do call.
