The government's Boiler Upgrade Scheme covers up to £9,000 of the cost. Sailax handles your eligibility, the paperwork and a fully MCS-certified installation — across London & Birmingham.
A typical heat pump installation costs £7,000–£14,000. With the Boiler Upgrade Scheme applied directly at installation, eligible homeowners pay only the remainder — often as little as £1,500.
Illustrative split based on a representative installation. Your exact grant level and net cost are confirmed during your free eligibility assessment.
In plain English — the grant is applied by your installer, so it comes straight off your installation price. You never have to claim it back yourself.
We were on oil and dreading the cost. Sailax confirmed we qualified for the higher £9,000 grant and the whole thing came to a fraction of what we expected. Genuinely the easiest big home decision we've made.
What sold me was that they did a proper home survey before quoting — no guesswork. The MCS-certified team were tidy, on time, and finished in three days. House is warmer and the bills have dropped noticeably.
I was nervous about the government paperwork but Sailax handled the entire grant application for me. I just answered a few questions and they did the rest. Quote was fixed and there were no surprises at the end.
Rang on a Tuesday, had a reply within the hour and a survey booked that week. Older 1930s semi and they were honest about what we'd need first. No hard sell — exactly how it should be done.
The fixed-price quote was exactly what we paid — to the penny. Communication throughout was excellent and they checked in after the install to make sure everything was running properly. Highly recommend.
Switched from an old LPG boiler. The savings on running costs are real and the house holds heat so much better now. Grant covered the vast majority of the cost — wish we'd done it sooner.
There are lasting reasons to make the move — for your home, your bills and the long term.
Heat pumps typically run at 300–400% efficiency — producing three to four times more energy than they consume, cutting your heating bills.
Modern heat pumps work reliably in the UK climate and across a wide range of property types — from newer builds to older homes with the right setup.
Designed for reliability with minimal servicing — and no annual gas safety checks to arrange once you've made the switch.
A single system handles both space heating and domestic hot water — replacing your boiler and cylinder in one efficient unit.
Switching from oil or gas significantly reduces your home's carbon footprint — and gets cleaner as the grid continues to decarbonise.
With fossil fuel boilers being phased out, heat pumps are the forward-compatible choice — potentially adding value as the market shifts.
Some homeowners have had poor experiences — rushed jobs, missed grant details, little support afterwards. Sailax was built around a more considered approach.
