Norwich has a mixed bag of housing when it comes to heating, from Victorian terraces around Golden Triangle and Norwich-over-the-Water to newer estates out towards Costessey and Sprowston. Older properties often still run on back boilers or ageing combis tucked into airing cupboards, with pipework that's been patched up over decades, while newer builds tend to have system boilers or unvented cylinders that need a different kind of know-how. A heating engineer working across this patch needs to be comfortable with both, plus the odd rural cottage on the outskirts running on oil rather than mains gas, since not every village around the ring road has a gas main running to it.

The businesses listed here are pulled from public business listings and ranked mainly by review rating and how many reviews they've built up, with a small boost given to those that have a proper working website and phone number listed. We also check each business's homepage ourselves to confirm heating engineering is genuinely what they do day to day, which keeps plumbers who only dabble or unrelated tradespeople off this particular page. Any listing that's flagged as permanently closed gets removed as part of that process. Where you spot a Trust Verified badge next to a business, that firm has gone through our fuller verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company details. Our How We Verify page sets out exactly what that involves. For businesses without the badge, none of that has been independently checked by us, so it's worth doing your own homework before you book.

Before you commit to anyone, ask to see their Gas Safe registration card if the job involves gas appliances, and check the licence number against the Gas Safe Register yourself rather than taking it on trust. For boiler installations, ask whether they'll issue a benchmark certificate and building regulations notification, since you'll need both if you ever sell the property. It's worth getting two or three quotes for anything beyond a basic service or minor repair, particularly for full system replacements or moving a boiler location, as prices for the same job can vary by hundreds of pounds between firms in Norwich. Ask what's included in any quote, whether it covers a power flush, new thermostat, and disposal of the old unit, so you're not caught out by extras later.
How We Select & Rate The Best Heating Engineers in Norwich

Ranking is driven by review rating and review count from public business listings, with a small lift given to businesses showing a working website and phone number. We check each business's homepage to confirm heating engineering work is what they primarily offer, which keeps unrelated trades off this page. Listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified have gone through our fuller verification process, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information; see our How We Verify page for the full detail. Other businesses here haven't been independently checked by us, and their inclusion isn't an endorsement, so do your own checks before hiring anyone.

Recommended and Featured listings are paid placements, so a business's fee affects whether and where it appears. Every other listing is ranked on rating and review count from third-party business listings. How we rank & verify →

Frequently Asked Questions

How much does a heating engineer cost in Norwich?
A standard boiler service typically runs from around £70 to £120, while a full boiler replacement on a like-for-like basis usually sits between £1,800 and £3,500 depending on the make and whether it's a straightforward combi swap. Repairs vary hugely, a stuck valve or faulty pump might be £100 to £250 including parts, whereas a full system flush can run into several hundred pounds. Rural properties on oil heating tend to cost more for servicing than mains gas equivalents. Getting two or three quotes is normal practice here, and it's the easiest way to spot if someone's pricing is out of step with the local market.
Do I need a Gas Safe registered engineer for boiler work in Norwich?
Yes, for anything involving a gas boiler, gas fire or gas cooker, the engineer must be Gas Safe registered by law, not just qualified in general plumbing. Ask to see their Gas Safe ID card, which lists exactly what gas work they're certified to carry out, and check the card matches the person actually turning up on the day. You can verify any registration number directly on the Gas Safe Register website before booking, which only takes a couple of minutes.
How long does a boiler installation take?
A straightforward like-for-like combi boiler swap in a Norwich terrace or semi usually takes a day, sometimes finishing by early afternoon if access is easy. Moving the boiler to a new location, converting from a heat-only system to a combi, or dealing with older lead or steel pipework can push this to two or three days. Always ask upfront how long the job's expected to take and whether you'll be without heating or hot water overnight.
What's the difference between a combi boiler and a system boiler?
A combi boiler heats water on demand straight from the mains, so there's no need for a hot water cylinder or loft tank, which suits smaller properties like Norwich terraces with limited storage space. A system boiler works with a separate hot water cylinder, which usually copes better if you've got two bathrooms or high water demand at once. An engineer should look at your property's size, number of bathrooms and existing pipework before recommending either, rather than just quoting for a like-for-like swap by default.
Should I get a power flush when I have a new boiler fitted?
If your existing system is more than ten years old or you've had persistent cold spots on radiators, a power flush clears out sludge and debris that can shorten a new boiler's life. It typically adds £300 to £500 to the job but can prevent early breakdowns and keep the manufacturer's warranty valid, since many boiler warranties require proof the system was flushed properly. Ask your engineer whether they think it's necessary for your setup rather than assuming it's always required.
How do I choose between heating engineers in Norwich?
Start by checking the engineer's Gas Safe registration number yourself on the official register rather than relying on a card or certificate they show you. Ask for references or recent job photos from work done in Norwich, ideally on a similar property type to yours, whether that's a Victorian terrace or a newer estate build. Get written quotes from at least two or three firms covering the same scope of work, including parts, labour, disposal of the old boiler, and any certification they'll provide afterwards. Check whether they carry public liability insurance and ask to see proof of it, and read through recent customer reviews for patterns, particularly around punctuality, tidiness and whether they turned up when promised.
