Boiler Servicing in
South Shields

Wind off the North Sea carries salt, and your boiler flue sits in it all year. A yearly service is when someone actually looks at that. We come over from Houghton le Spring, about 12 miles away, to service boilers across NE33 to NE36. From £80 + VAT.

Engineer checking a gas boiler during a yearly service in South Shields

Salt air and your flue terminal

The part of your boiler that takes the weather is the bit outside: the flue terminal poking through the wall. Near the coast it gets a steady coat of salt, and over the years that works on the grille, the fixings and the seal where the flue meets the brickwork.

On a service we go outside and look at it properly. Is it corroded? Is the terminal guard sound? Has the wall seal cracked, letting rain track back inside? Then, back indoors, we check the seals on the boiler case, because a room sealed boiler only stays safe while that case is airtight.

Anything we are not happy with, you hear about in plain words, with a price, before we touch it.

What happens when we service your boiler

You should come away knowing whether your boiler is safe, whether it is burning gas the way the maker intended, and whether anything is starting to wear. That takes real measurements, not a glance at the front panel.

We time the gas meter to work out how much gas the boiler is using and compare that with the published figure. A flue gas analyser then tells us how cleanly it is burning. After that we open the boiler up: burner, electrodes, heat exchanger, fan, condensate trap and the internal seals. Safety devices are tested so we know they will shut things down if they need to. The expansion vessel and system pressure are checked too, since a flat vessel is a common cause of pressure dropping in the middle of winter. The full list sits on our main boiler servicing page.

Homes close to the seafront

If you live near Marsden, Horsley Hill or anywhere the wind comes straight in off the water, the outside of the flue is where we spend a bit more time. Salt speeds up corrosion on metal terminals and fixings. A terminal that has started to break up can change how the flue gases clear the wall, so it is worth catching early. We also look for a white crust or staining around the terminal, which tells us how hard the weather is hitting that wall.

Tyneside flats in the older streets

Plenty of the older streets in South Shields are lined with Tyneside flats, one flat upstairs and one down, each with its own boiler. Space is tight, so boilers end up in cupboards or kitchens with the flue going out through the front or back wall. In an upper flat the condensate pipe often has a long, awkward route down to a drain. We check that route at the service, because a pipe that freezes in a cold snap will lock the boiler out until it thaws.

Keeping your warranty

Worcester Bosch, Vaillant and Baxi all expect a yearly service by a Gas Safe engineer to keep their warranty valid. Keep the paperwork we leave you. If you ever need to make a claim, it is the first thing the manufacturer asks for.

Letting a flat or house

A landlord gas safety record, the CP12, is a legal check every year. It is a different job from a service, though we can do both in the same visit. Our landlord boiler service page explains how that works.

What it costs

A standard gas boiler service starts from £80 + VAT. We confirm the price for your boiler when you book, so you know where you stand before we arrive.

What we check on a South Shields service

The coast adds a couple of jobs to the usual list. Here is what we look at.

🏠
Flue terminal
Inspected outside for salt corrosion, a damaged guard and a failing seal where it meets the wall.
🔒
Case seals
The boiler casing seals checked, because a room sealed boiler relies on them to keep flue gases out of the room.
📊
Gas rate
Worked out at the meter and compared with the maker's figure for your model.
💨
Combustion reading
An analyser in the flue shows how cleanly and safely the gas is burning.
💧
Condensate route
Followed from boiler to drain, which matters most in upper flats with long outside runs.
🛡️
Safety devices
Each one tested so it will shut the boiler down if something goes wrong.
Boiler stopped working altogether?

A service will not get a broken boiler going again. For a fault, our repair visit starts with a fixed price diagnosis from £89, and there is no call out fee on top.

Boiler service questions from South Shields and the Boldons

What people in NE33 to NE36 tend to ask before booking.

Do you service boilers in East Boldon, West Boldon and Boldon Colliery? +
Yes. The Boldons are part of our regular area, NE35 and NE36, and the price is the same as for South Shields itself.
I live near the seafront. Does my boiler need anything extra at its service? +
It gets the same full service, with extra attention on the flue terminal outside and the seals on the boiler case. Salt air speeds up corrosion on the terminal, so we look for damage early rather than waiting for it to cause a problem.
Can you service the boiler in an upstairs Tyneside flat? +
Yes. Access is usually through the flat's own front door and stairs. We pay close attention to the flue position and the condensate pipe, which often has a long route down the outside wall from an upper flat.
How much is a boiler service? +
From £80 + VAT for a standard gas boiler. We confirm the price for your boiler when you book.
Why does a boiler need servicing every year? +
It confirms the boiler is burning safely, spots worn parts before they fail in winter, and keeps the manufacturer warranty valid. Most makers set the yearly service as a condition of their warranty.
Can you do a landlord gas safety certificate at the same time? +
Yes. The CP12 and the service are separate checks, but one visit can cover both, so your tenant only needs to be in once.
How long does it take? +
Usually about an hour. Longer if the flue is boxed in and needs opening, or if something needs a closer look.
