From a leaking tap or a radiator that won’t heat up to changes to your plumbing or problems with your central heating, Willis Heating Ltd provides a wide range of general plumbing and heating services across Seaford, Newhaven, Peacehaven, Lewes and the surrounding area.
Some jobs need urgent attention. Others are those annoying problems you’ve been meaning to get sorted for months. And sometimes you simply need an experienced plumber to tell you what’s wrong and what it will take to put it right.
Whatever the problem, our qualified plumbers and heating engineers will take the time to investigate it properly, explain what we’ve found and recommend the most appropriate solution.

Not every plumbing job is a major project.
A dripping tap, leaking pipe, toilet that won’t flush properly or a problem with your water supply can be inconvenient and, if left unresolved, may eventually cause damage to your home.
Our plumbers can help with all kinds of general plumbing work, including:
If you’re not sure exactly what’s causing the problem, don’t worry. Finding faults and diagnosing plumbing and heating problems is an important part of what we do.
Tell us what you’ve noticed and we’ll take it from there.
If your boiler appears to be working but your home isn’t heating properly, the problem may be elsewhere in the central heating system.
We can investigate problems such as:
Rather than automatically replacing components, we’ll investigate what’s happening and try to establish the cause of the problem first.
Radiators can become less effective over time, and older radiators aren’t always well suited to the way a room is now being used.
We can repair or replace radiators, valves and associated pipework, whether you’re dealing with a fault or simply want to improve the heating in a particular room.
If you’re renovating or redecorating, we can also help you choose new radiators that provide the appropriate heat output while working with the style and layout of the room.
That might mean a straightforward panel radiator, a vertical radiator where wall space is limited, or something more decorative.
The important thing is that the radiator isn’t chosen on appearance alone—it needs to provide enough heat for the room.
Good heating controls can make your home more comfortable and give you greater control over when and where you’re using energy.
If your existing controls are outdated, difficult to use or no longer working properly, we can advise on suitable replacements and upgrades.
This can include:
As Nest Pro Installers, we can also advise on and install Nest heating controls and help you get them set up correctly for your home.
If your heating system suffers from cold radiators, poor circulation or a build-up of sludge and debris, it may benefit from cleaning.
Depending on the condition of the system, we can advise whether power flushing or another method of system cleaning is appropriate.
Cleaning isn’t the answer to every heating problem, so we’ll look at the symptoms and condition of your system before recommending it.
Where it is needed, removing accumulated debris can help restore circulation and allow the heating system to work more effectively.
We’re also here when you want to change something rather than repair it.
You may be moving a washing machine, adding a new sink, altering a kitchen, converting a room or making improvements elsewhere in your home.
Our plumbers can alter existing water supplies, waste connections and pipework to accommodate changes to your property.
If the work forms part of a larger renovation, we’re happy to discuss the plumbing and heating requirements at an early stage so they can be properly planned rather than dealt with as an afterthought.
Our appropriately qualified Gas Safe registered engineers can undertake gas work within the scope of their qualifications, including the installation and connection of domestic gas appliances where appropriate.
If you’re considering a new gas cooker, fire or other appliance, talk to us about what’s required before installation.
We’ll make sure the relevant gas work is carried out safely and correctly.
We also install, repair and service boilers, but we’ve given these services their own sections of the website so you can find the information you need more easily.
If your boiler has stopped working, is displaying a fault code or you think it needs replacing:

For annual maintenance and keeping your boiler properly serviced:

Sometimes the most difficult part of a plumbing or heating problem is working out what’s actually causing it.
Our engineers have experience across plumbing, heating and gas systems, which means we can look beyond the most obvious symptom and investigate the wider system where necessary.
We’ll explain what we find in straightforward terms and discuss the options with you before carrying out additional work.
For us, good service isn’t just about fixing the immediate problem. It’s about doing the job properly and helping you understand what has been done.
Willis Heating provides general plumbing and heating services throughout:
Our team regularly works in homes throughout the district, from small plumbing repairs to more involved heating work.
