How it works
From first question to a working boiler. Here is exactly what happens.
1. Answer the questions
The quote tool asks about your current boiler, the fuel it uses, whether you want to switch to a combi or move the boiler, your home, how many bedrooms and radiators you have, how much hot water you use, and where the flue goes. Most answers are one tap.
2. See your recommended boilers
We recommend three boilers that suit your home, from Ideal, Vaillant, Worcester Bosch and Baxi, each with a fixed price including installation. You can also browse every other suitable boiler from 11 makers.
If your answers show something we need to check first, such as a back boiler, LPG or oil, or a flue that may not meet the rules, we ask for your details and give you a personal price instead.
3. Add extras
Optional extras each have a fixed price, such as a heating system flush (£198), new thermostatic radiator valves (£40 each) or a smart thermostat (from £79).
4. Pick your date
Choose any day from tomorrow, up to 60 days ahead.
5. Pay securely
Pay a £500 deposit or the full price on Stripe’s secure payment page. Choosing the deposit means the rest is paid before fitting day. You will be asked to confirm that you want us to start arranging your installation within the 14-day cancellation period, as the law requires.
6. We confirm
We call or email to confirm your date and arrival time, and check anything we need to know about your home.
7. Installation day
A Gas Safe registered engineer removes your old boiler, fits and commissions the new one, and shows you how to use it and its controls. We register the boiler with the manufacturer for you.
8. Afterwards
Your installation work has our 12-month warranty, and your first annual service with Southwark Heating is half price. You can create a customer account with Southwark Heating to see your installation, invoices and certificates in one place.
