They picked up straight away and had someone over within the hour. The plumber was friendly, explained the problem, and had it fixed without making a mess. Felt like a genuine and dependable service.

His immense experience of our type of boiler, saved us having to buy a new one. Which was recommended by a different contractor!

I would definitely highly recommend them Paola Nyderek12 November 2024Trustindex verifies that the original source of the review is Google. I was really stressed and worried when my Pulsacoil 2000 boiler suddenly stopped working and I had no hot water. With the weather getting colder and having a dependent, this was a major problem. I tried calling a few places for help, but couldn't find the right solution until I contacted Iky. He was super friendly and helpful, not trying to rip me off at all. He walked me through fixing the issue over the phone and we got it sorted out without any stress. I can't thank him enough and would definitely recommend him to anyone dealing with Pulsacoil problems. Thank you Iky. Claire V12 November 2024Trustindex verifies that the original source of the review is Google. Great job by Iky and his kind and competent staff. They worked fast but with precision and we had some nice chats in-between. Highly recommend.
A Gledhill boiler can lose pressure due to several common issues such as a leaking system, a faulty pressure relief valve, or a problem with the expansion vessel. Small leaks in pipework or radiators can gradually drop the pressure, even if they’re not visible. If the expansion vessel has lost its charge or is damaged, the system cannot maintain correct pressure levels. At Rapid React Plumbing, our engineers diagnose pressure problems quickly and carry out permanent repairs to stop recurring faults. Ignoring low pressure can eventually cause your boiler to shut down, so it’s best to call our expert team as soon as you notice fluctuations.
The cost of repairing a Gledhill boiler can vary depending on the fault, the model, and whether any specialist parts are needed. Common repairs like fixing leaks, replacing sensors, or resetting the system may start from £90–£150. However, replacing components like pumps, heat exchangers, or circuit boards can increase costs to £200–£500 or more. Rapid React Plumbing provides transparent, fixed-price quotes before starting any work. Our engineers carry many Gledhill parts on hand, which can speed up repairs and save on costs. We also offer no-obligation diagnostics to help you make an informed decision.
Yes, most Gledhill boiler parts are still available, even for older models like the Pulsacoil, Boilermate, and Electramate systems. While some discontinued models may have harder-to-find parts, Rapid React Plumbing works with trusted suppliers to source genuine or high-quality replacement parts quickly. Our engineers have extensive experience with Gledhill systems and can advise whether repair or replacement is the best option. Acting early when a fault appears helps ensure parts are still accessible and avoids longer downtime.
In many cases, yes — the engineers at Rapid React Plumbing aim to provide same-day Gledhill boiler repairs whenever possible. We carry a stock of the most common Gledhill parts, which allows us to fix typical issues like leaks, sensor faults, and electrical problems on the spot. If a rare part is required, we can usually source and fit it within 24–48 hours. Our local team offers fast-response appointments, including evenings and weekends, to get your heating and hot water back on without delay.
It depends on the age, condition, and fault with your boiler. If your Gledhill system is over 15 years old and suffering from frequent breakdowns, it may be more cost-effective to replace it with a modern, energy-efficient unit. However, if the fault is minor — such as a leaking valve, sensor fault, or pump replacement — repair is often the best option. Rapid React Plumbing engineers will give you honest advice, a clear breakdown of costs, and the pros and cons of each choice so you can decide confidently. We also offer new boiler installations if replacement is necessary.

Whether it’s an unvented thermal store, electric-only system, or a combination boiler, our certified engineers have the experience and specialist knowledge to handle it. We also provide annual servicing to keep your Gledhill boiler running safely and efficiently, reducing the risk of breakdowns.
