What Our Customers Say

Tatiana Serganova

Really impressed with the service. Nick was able to come out on the same day, investigate the issue thoroughly, and didn’t charge me for the investigation.What I particularly appreciated was the transparent pricing and honest advice. Rather than pushing for an expensive replacement, he explained the different options and recommended the most sensible and cost-effective solution.I had previously spoken to two other plumbers who quoted significantly more for the same work, so the difference was quite striking.Professional, honest and reasonably priced. I would definitely recommend and will use them again.

After having real problems with our hot water supply tank Nick was recommended to us by our neighbour. Nick came at very short notice and immediately was able to work out a solution that a well known plumbing company had missed! He was brilliant -knowledgeable, with good communication and very positive. He made us feel confident that he could solve the problem.And he did!Highly recommend him.

I had a great experience with Nick from Primeworks Heating & Plumbing Ltd. He helped me repair the boiler and install a gas isolation valve. He responded quickly to messages, arrived on time, and carried out the work professionally and efficiently. He was polite, friendly, and took the time to explain what needed to be done. The whole process was smooth and stress-free. Highly recommended!

Nick and his team are excellent! Very friendly, organised and quick to resolve any water problems we've had. Boiler serviced and repaired, including making sure we were compliant, which wasn't done by previous companies. Struggled with poor water pressure with our filter tap, which we had installed as part of our kitchen refurb. They did it properly and I no longer have to wait 4 mins to fill the kettle - literally life changing! Fixed various other issues promptly and easily. It was also the little things like wearing shoe covers so they didn't make a mess when walking through our house. So refreshing to find a company that actually cares about great service!

Primeworks Heating & Plumbing removed an old gas combi boiler and replaced it with a new Vaillant boiler in my flat. They also replaced three radiators.Nick and his team were excellent throughout the whole process. They were knowledgeable, professional and friendly. Good communication, attention to details and tidiness was also appreciated. Highly recommended.

I was recommended to Nick by a friend when I needed a knotty water flow issue resolved in a flat. Nick’s advice was clear and straightforward, far far better than any other plumber we had approached. The cost was reasonable and the work completed quickly, simply and - importantly - totally successfully.I have since chosen Nick and his team for a variety of jobs, including refitting a shower room. All jobs have been done to the highest standard.Most recently, I had a boiler problem (they always happen in the coldest weather!) and Nick fitted the job within the same day, resolved it, serviced the boiler as well - all for effectively a ‘call out’ charge.I cannot recommend Primeworks highly enough - friendly, crystal clear, on time and competitive. A breath of fresh air!

I can't recommend Nick and Johnny highly enough! They have been totally brilliant, completing a full installation of a new boiler and heating system throughout our home, as well as fitting our bathroom and connecting our gas cooker. It hasn't been a simple project as we have been doing a lot of the decorating work ourselves but they have been so kind, patient, generous and professional with their time and expertise throughout.We're extremely grateful and so glad we found Primeworks!

Nick and team did a great job with a new boiler and radiator installation at my flat. Every stage of the process from quoting to final clean-up after the job was done efficiently and professionally. The cost of the work was very reasonable.

Primeworks heating & plumbing, installed a new Vaillant boiler and replaced some radiators for me. Nick and Johnny have been excellent and provided a fantastic service. They were very tidy, knowledgeable, and fairly priced. I originally had a survey done by HeatingHub, and based off of my requirements they recommended Primeworks for the install. The HeatingHub only recommend plumbers that work to their higher efficiency and installation standard.

I can highly recommend Nick and the quality of his work. He completed a bathroom refurb and we were so impressed with him, that we asked him back to fit some radiators.We are so pleased that we found someone who clearly takes pride in their work, has excellent communication skills and is punctual. He turns up when he says he will! He also always makes sure that he leaves no mess behind when he's finished a job. Book him and his team, you won't be disappointed.

Frequently Asked Questions

General Questions

What areas do you cover?

We serve all of South-East London, including Lewisham, Greenwich, Blackheath, New Cross, Dulwich, Forest Hill, Lambeth, and Beckenham. If you're nearby and not sure whether your address is in range, call 07534 469 008 and we'll confirm before you book.

How long have you been trading?

Primeworks is a family-owned business led by Nick Vrabiescu, who has over ten years of hands-on experience in heating and plumbing engineering. We built the company on local trust in South-East London and Nick personally oversees every job.

Are you Gas Safe registered?

Yes. Every Primeworks engineer working on a gas appliance is Gas Safe registered, and our unvented-cylinder engineers also hold the G3 Unvented Hot Water qualification. Every engineer carries an ID card you can ask to see on arrival.

What are your working hours?

We operate seven days a week. Standard hours are Monday to Friday 08:00 to 21:00, and Saturday to Sunday 08:00 to 18:00. For genuine no-heat or no-hot-water emergencies, we treat the job as a priority repair within those hours.

Do you offer free quotes?

Yes. Every quote we give is free and no-obligation. We come out, survey the work, and send you a clear written price with no hidden extras. For boiler installations and unvented cylinders we'll do the mains pressure / system flow check at the same visit.

What payment methods do you accept?

We accept bank transfer, all major credit and debit cards, and cash. Payment is taken on completion. For larger boiler installations or unvented cylinder projects we're happy to discuss staged payments so you can plan around the work.

How do I know if I need a new boiler or just a repair?

Generally, if your boiler is over 10 to 15 years old, frequently breaks down, or your energy bills are rising, a replacement is more cost-effective. During a site visit, we assess the repair-versus-replace value to ensure you aren't pouring money into an inefficient system.

How long does a typical boiler installation take?

A straightforward like-for-like swap usually takes one day. If we are converting your system (such as moving from a traditional boiler to a modern combi boiler) it typically takes two to three days to account for pipework upgrades and tank removal.

Will there be a lot of mess during the installation?

We treat your home with total respect. Our engineers use protective floor coverings and dust sheets in all work areas. Once the installation is complete, we remove your old boiler and any debris, leaving your home as clean as we found it.

Does the installation include a system flush?

Yes, all our installations include a free system flush and inhibitor treatment. This process removes sludge and debris from your radiators and pipes, which is required to keep your manufacturer's warranty active and ensures maximum system efficiency.

What kind of warranty comes with a new boiler?

We work with leading manufacturers to provide comprehensive warranties, typically ranging from 5 to 10 years depending on the model. As accredited installers, we can often offer extended warranties that are not available to the general public.

How often should I have my boiler serviced and why is it necessary?

You should have your boiler serviced every 12 months. This is necessary to keep the manufacturer's warranty active, maximise the boiler's efficiency and ensure safe, reliable operation.

I have no heating or hot water, is this an emergency?

Yes. If your system has failed completely, we prioritise your call as a priority repair. Before calling us, we recommend checking your prepaid meter (if applicable), ensuring your thermostat has fresh batteries, and checking if your boiler is displaying a specific fault code.

What is included in a standard boiler service?

Our comprehensive service includes a visual inspection for leaks and corrosion, a flue gas analysis to check for carbon monoxide, a check of internal components and gas pressure, and a clean of the main heat exchanger if required. We provide a digital service record on completion, and a FREE radiator check is included with every boiler service.

How much does a boiler service or repair cost?

Annual servicing typically runs between £100 and £300. Repair quotes depend on what's failed and which parts are needed, and we'll give you a fixed price after diagnosing the fault. There's no hidden call-out fee rolled into the bill afterwards.

Do you offer Landlord Gas Safety Certificates (CP12)?

Yes. We carry out annual CP12 inspections for landlords and managed portfolios across South-East London. We test every gas appliance, check for leaks, and issue the certificate on the same visit wherever possible. We can set up renewal reminders so you never miss the date.

Can you repair every boiler brand?

Yes. Our engineers regularly work on Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm, and most other major brands. We carry common spares in the van, and when a manufacturer-specific part is required we'll order it the same day and book the return visit straight away.

What is an unvented cylinder and how does it work?

Unlike a traditional gravity-fed system, an unvented cylinder is connected directly to your mains water supply. This means you don't need a cold water tank in the loft, and your hot water is delivered at mains pressure, providing much stronger flow rates for showers and taps throughout the home.

Can my home support an unvented cylinder?

Most modern homes are suitable, but it depends on your incoming mains water pressure and flow rate. We conduct a mains pressure test during our initial survey to ensure your supply is strong enough to deliver the performance benefits an unvented system offers.

How long does the installation of an unvented cylinder take?

The installation of an unvented cylinder typically takes between one and two days, depending on the complexity of the pipework and whether we are removing old water tanks from your loft. As part of our service, we also remove all rubbish, any old water tanks from your loft and any debris from the old cylinder, leaving your home clean and tidy.

Are unvented cylinders safe?

Yes, they are extremely safe when installed correctly. They are fitted with multiple safety features, including expansion vessels and temperature/pressure relief valves. Because of these high-pressure safety requirements, they must only be installed by a qualified engineer with a G3 Unvented Hot Water qualification.

How much space do I need for the installation?

One of the biggest benefits is that you can remove the bulky water tanks from your loft, freeing up storage space. The cylinder itself is usually housed in an airing cupboard or utility room. We will ensure the chosen location provides enough clearance for the pipework and future maintenance.

Can I have underfloor heating fitted in an existing home?

Often, yes. It is most straightforward as part of a renovation, extension, or new floor build, where the pipe loops can be laid before the new floor goes down. Retrofitting into an existing floor is also possible using low-profile systems. We survey the floor construction first and tell you honestly what will work best in your property.

Does underfloor heating work with my boiler?

Yes. Wet underfloor heating runs off your existing gas boiler or cylinder in the same way as radiators, just at a lower flow temperature via a manifold and blending valve. It pairs particularly well with modern high-efficiency condensing boilers, which run most efficiently at those lower temperatures.

How much does underfloor heating cost?

It depends heavily on the floor area, the floor build-up, and how many rooms or zones are involved, so we quote after a survey rather than over the phone. Every quote is fixed and in writing, and it includes the manifold, controls, and full leak testing and commissioning.

Can I control underfloor heating room by room?

Yes. Each circuit runs back to a manifold, and we can set the system up in zones so different rooms are controlled independently. That means you can heat the rooms you are using and keep the rest cooler, which helps with comfort and running costs.
