Professional & Affordable Boiler Service in Wellingborough


Your Boiler Serviced By a Trusted Trader Plumber

BOILER SERVICE WELLINGBOROUGH

Boilers rarely choose a convenient time to give up. It usually happens on the first cold morning of the season, when the heating is on, and the house is very quiet. An annual boiler service in Wellingborough is a simple habit that prevents those mornings from coming. Assett Plumbing has been keeping homes warm across the town and the wider Nene Valley for over 30 years, and an annual check is the cheapest, least dramatic way to keep your boiler running safely and affordably.



Whether you’re in a Victorian terrace near the town centre, a 1970s house on Queensway, or one of the new properties on Stanton Cross, the service itself is the same meticulous task: a thorough check of how your boiler burns, breathes and behaves, carried out by a Gas Safe Registered Engineer who lives and works locally.

What Actually Happens During Your Service

Boiler service is more than just a quick glance and a tick in the box. When our engineers arrive, they inspect the parts of your boiler that have worn out, clogged or lost tolerance over a year of daily use. In simple terms, this means:

  • A visual inspection of the boiler, pipework, flue and controls so that anything clearly wrong can be identified before it becomes costly.
  • Checking gas pressure and flow, so that the boiler is burning efficiently rather than wasting money on the flue.
  • Testing the flue for safe combustion and ensuring there are no signs of carbon monoxide escaping into your home.
  • Inspecting the main internal components - the heat exchanger, burner, electrodes and seals - and cleaning where necessary.
  • Confirming that safety devices have been cut correctly, and finishing with a written record of the results.

Most services take between 30 minutes and an hour, depending on the make and condition of the boiler. If we find something that needs attention, you'll hear about it in clear language, with a free itemised quote before we start the next task. No jargon, no pressure.

Why Wellingborough homes get more out of an annual service

Two things about this part of Northamptonshire make regular servicing more than just a box-ticking exercise.

The first is the water. Wellingborough is located in a hard water area, and over time that mineral element leaves scale inside your central heating and around the heat exchanger. Scale causes many local boilers to start making a rattling or rattling noise, lose efficiency and eventually lock out. The service catches that build-up early, and if the system is already clogged, we can talk to you about a power flush in Wellingborough to clean it out properly.



The second is the mix of housing here. Older terraces around Midland Road and the town centre often run boilers that have been in operation for years and need to be looked after. At the other end of the scale, new estates at Stanton Cross and Glenvale Park almost always come with a manufacturer’s warranty which only remains valid if the boiler is serviced every year. Leave the service, and you can quietly lose the cover you paid for. A little note in your diary keeps it safe.

Signs Your Boiler is Asking to be Looked At

It’s best to book a service before there’s a problem, but boilers do give signs of a leak. It’s worth getting in touch early if you notice:


  • A banging, whistling or roaring sound when heating - often the ones we mentioned above.
  • A pressure gauge is leaking and needs to be topped up more often than usual.
  • Radiators that stay cold at the bottom or take a long time to heat up.
  • A pilot light or flame that is yellow or orange instead of a crisp blue.
  • Heating bills are rising for no apparent reason.


If your boiler has already stopped working, you don’t need a service first - it needs a repair. Take a look at our boiler repair in Wellingborough, or if it’s an after-hours emergency, our Wellingborough emergency plumber team will try to be with you within the hour. And if an engineer determines that your boiler has truly reached the end of its life, we will provide you with the details of replacing the boiler to ensure it doesn't fail again.

Booking your boiler service - and what it costs

We keep the booking process simple. Call the Wellingborough line on 01933 717044, let us know when it suits you, and we’ll arrange an appointment that suits your day, rather than tying you up in a vague morning window.

Our standard boiler service is currently £60 + VAT, and there are no call-out fees added on top - the price you quote is the price you pay.

Our engineers cover Wellingborough Monday to Saturday, and because we’re a truly local team, you won’t have to wait days for someone to travel across the county.

Frequently Asked Questions

It's recommended that you have your boiler serviced at least once a year, and always by a Gas Safe registered heating engineer, to keep it running safely and efficiently.
A boiler service from Assett Plumbing includes a gas pressure check, a flue test to check for unsafe emissions, a check of the boiler and its controls, a visual inspection for leaks or corroded parts, and guidance on using your boiler safely.
No, a boiler service and a Gas Safety Certificate (CP12) are two different things. A service checks that your boiler is running safely and efficiently. At the same time, a Gas Safety Certificate is a legal document, usually needed by landlords, confirming all gas appliances in a property are safe. Assett Plumbing can carry out both, so let us know which you need when you call.
Yes, part of every boiler service includes a flue test to check for unsafe emissions, which is one of the main ways a carbon monoxide leak is caught early. Regular servicing is one of the most effective ways to keep your home safe.
Yes, electric boilers still benefit from annual servicing to check efficiency and safety, though since there's no gas involved, they don't require the same flue or gas pressure checks as a gas boiler. This page's service covers gas boilers specifically — call to ask about electric boiler servicing.
Boiler service pricing depends on your boiler type, but Assett Plumbing offers a competitive price that includes a full visual survey of the rest of your system and a written report. Call 01933 717044 for an exact quote.
Between annual services, keep your boiler pressure within the recommended range, bleed your radiators if they're cold at the top, and keep the area around your boiler clear. If you notice unusual noises, smells, or a pilot light that isn't blue, contact a Gas Safe engineer straight away.
Assett Plumbing is a local company with plumbers based in Wellingborough, over 30 years of technical experience, no call-out fees, and all work guaranteed. We're approved and vetted by Northants County Council's "Buy with Confidence" scheme.
