Your questions

New boiler & installation FAQs

How much does a new boiler cost?
It depends on the boiler, the brand and how much work the install involves, which is exactly why we survey first and give you a fixed-price quote. There are no call-out charges and no added ULEZ fees, so what we quote is what you pay. Finance options are available if you'd rather spread the cost.
Which boiler is right for me?
That depends on the size of your home, how many bathrooms you have and how you use hot water. During the free survey we size the system correctly and recommend the right boiler and brand (Worcester Bosch, Vaillant, Baxi, Ideal or Bosch) for your home and budget. No pressure to decide on the spot.
How long does an installation take?
Most straightforward boiler swaps are done in a day. A full central heating install or a more involved job usually takes a day or two. We'll confirm the timescale in your fixed quote and work tidily and on time.
Do you offer finance?
Yes, finance options are available so you can spread the cost of a new boiler or heating system. Ask us about it when we survey and we'll talk you through what's available.
Do you remove the old boiler?
Yes. We disconnect, remove and dispose of your old boiler as part of the installation, and tidy up before we leave. You're left with a clean, working system, not a mess to clear yourself.
What guarantee do I get?
We back our installation work with a 12-month guarantee, register the manufacturer's warranty on your new boiler and hand over the Gas Safe certification. Everything is documented so you're covered and compliant.
Do I actually need a new boiler, or can mine be repaired?
We're repair-first. We only ever recommend a new boiler if yours genuinely can't be fixed safely or economically, and we'll explain exactly why. If a repair makes more sense, we'll tell you. No pressure-selling.
