How we work
Four steps, and no surprises at any of them.
A new boiler is a big thing to trust someone with. Here's exactly how a job runs with Lock & Lindfield — who does what at each stage, and what you get back — so there are no unknowns before you pick up the phone.
01
Free survey and honest advice
We come out, look at your system and talk through the options — combi, system or regular boiler, the right size for your home, and which A-rated brand suits you. As reviewers put it, we "offer great advice" with "no pressure."
What you get at this stage
A free, no-obligation survey and honest advice on the right boiler and brand for your home — with no pressure.
02
A clear, fixed quote
You get a clear written quote covering the boiler, the power flush, magnetic filter, controls and all pipework — new boilers from £2,280, with finance available. No surprises added later.

Warranty registered, and we're still here
We register your manufacturer warranty (up to 12 years), leave you a free smart thermostat, and back our own work with a 5-year workmanship guarantee. Annual servicing keeps it all valid.
