A new boiler is a big decision. You deserve a team you can trust.

For more than 45 years, families across Coventry and Warwickshire have trusted Custom Heat to keep their homes warm. We’re not a faceless online retailer or a one-person operation juggling jobs. We’re a local, family-run business with our own employed, Gas Safe registered engineers and a showroom in Rugby.

Summer is the smartest time to replace an ageing boiler: our diaries are freer, so you get an unhurried survey and your new boiler running long before the cold returns. And this summer, the choice is yours: 10% off your installation, or a full year of cover with a free Care Plan. Two ways to say yes.

Your choice of summer offer — 10% off, or a free 12-month Care Plan worth £240.
Our own engineers, never subcontractors — the people who quote your job are the people who fit it.
Nothing to pay upfront — flexible finance from 0% APR, and we only invoice once the work is complete.

Why replace your boiler this summer?

When the cold weather arrives, heating engineers across the country are stretched thin with emergency breakdowns, and a new boiler can mean a long wait or a rushed job. Sorting yours in the summer means the opposite: a relaxed survey, an installation date that suits you, and a warm home ready well ahead of winter.

And to reward homeowners who plan ahead, this summer you choose how you benefit.

Take 10% off your installation if you’d rather have the saving.
Or choose a free 12-month Care Plan (worth £240), and we’ll look after your boiler for a full year, so it’s protected, your warranty stays valid, and we’re a single phone call away if anything ever needs attention.

Whichever you pick, there’s no better time to take advantage of our off-peak offer.

The reassurance of a national name. The care and value of a local team.

Choose the free Care Plan, and here’s exactly what a year of cover gives you:

Your new boiler’s manufacturer warranty stays valid
Unlimited call-outs, with no excess and no call-out fee
Guaranteed same-working-day call-out, reported before 10am, Monday to Friday
Parts and labour on covered breakdowns
A dedicated phone line straight to our Head Office team
All work carried out by our own experienced, employed engineers

Worth £240, and genuine peace of mind the first time something goes wrong. After your free year, you can keep your cover from as little as 41p a day.

Spread the cost, with nothing to pay upfront. In partnership with Novuna Consumer Finance, we offer 0% APR finance for up to 2 years, longer plans for lower monthly payments, and a buy-now-pay-later option with nothing to pay for the first 12 months. Subject to status. We only ask for payment once your boiler is installed. Your chosen summer offer applies either way.
