At Design Heating, we handle boiler projects of every scale — from a seamless replacement to full system upgrades and servicing. We bring you the professionalism and certification of a national outfit, but with local care, clarity, and accountability.
We’re experienced in sourcing, sizing, and installing boilers suited to your property and energy supply:
Gas boilers provide reliable heating and hot water, while combi boilers deliver both from one compact unit, saving space and providing instant hot water.
Ideal for rural Norfolk homes without mains gas, LPG boilers use bottled or bulk gas to provide efficient, flexible heating and hot water throughout the property.
Perfect for off-grid or remote properties, oil boilers deliver consistent heating and hot water, offering a dependable solution where other fuels aren’t available.
We partner with trusted manufacturers (e.g. Vaillant) and match the model to your home’s design, size, and heating needs.
If any of the following apply, a replacement may deliver better
performance and lower costs:
Your boiler is over 10 years old or no longer under warranty
Your energy bills have risen sharply despite usage remaining similar
You’ve experienced frequent breakdowns or costly repairs
You’re extending your home or changing your heating layout
You wish to switch fuel type (e.g. from oil to gas or LPG)
We believe in transparency.
A typical boiler installation includes:
Supply and installation of the boiler unit and controls
All associated pipework work or modifications
Commissioning, flushing, pressure testing, and system balancing
Full handover, including user guide and warranties
Final inspection and certification
All quotes are itemised and confirmed before work begins — no hidden extras.
The Boiler Upgrade Scheme gives you £7,500 towards switching to an efficient air-source heat pump. As one of a small number of MCS-certified installers in East Anglia, We’ll handle the paperwork and make the process straightforward from start to finish.
We live and work in this region — we know local housing types, typical issues, and common constraints.
We don’t just drop in a boiler: we design systems that match your layout, your usage, and your long-term goals.
Our accreditations include Gas Safe, MCS, NAPIT, RECC, IWA, and membership in the Boiler Upgrade Scheme. You get big-company standards with homegrown accountability.
You’ll always see what you’re paying for — we’ll explain every item, every step, and every decision.
We're proud to hold accreditations that you’d usually have to go to a national company for - giving you peace of mind that your home is in safe, experienced hands.
