What we do
One company for the temperature of your home
Heating and cooling are usually two different phone calls, two different firms and two different sets of excuses. The house that is freezing in January is unbearable in July. We do both.

Heating
Boiler installation
Old boiler on its last legs, or already gone? Send us a few photos of what you have now, tell us about your home, and we'll put a written price in front of you.

Cooling
Air conditioning installation
Most houses here were built to hold heat in, not let it out.

Heating and cooling
Heat pump installation
A heat pump is a good fit for some houses and a poor fit for others, and there is a lot written about them that pulls hard in both directions.

The price promise
We will beat any genuine like-for-like quote
Got a written quote from someone else? Show us. If it is genuinely the same work, the same spec and the same standard, we'll beat it. The terms fit on half a page and we'll send them to you before you commit to anything.
No hidden extras
The inclusions and exclusions are written down before you commit, not discovered on the day.
No finance games
We do not offer finance, so nothing is priced backwards from a monthly figure.
Experienced people
A new company built on more than 30 years of combined plumbing and heating experience.
A tight patch
We only work where we can get back to you the same week.
How it works
Tell us once. We take it from there.
The awkward bit is usually everything before you commit. Ours is one short form, a person reading it, and a number in writing. If you would rather talk it through, the phone still works.
- 01
Tell us about your home
Your setup, your hot water, your property, and a few photos of what you have now. A couple of minutes on a phone.
- 02
Get your price in writing
What is in it, what is not, and what happens if something turns up.
- 03
Pick a date
A date, a duration, and the name of who is coming.
- 04
We fit it
Floors covered, old kit gone, controls explained before we leave.
Where we work
An hour’s drive of Doncaster
We keep the patch to what we can genuinely get back to. That is the whole reason for drawing the line where we have, and it is the bit that matters on the day something needs a second look.
Heating
Warm in January
Boilers and heat pumps, fitted properly, at a price agreed before we start. Most swaps are a single day.
Cooling
Sleepable in July
Air conditioning sized for your room and sited to be quiet. Most single rooms are done in a day.

What a new boiler costs
It's the most-searched question in this trade and the one most companies answer worst. Here's what moves the number, so you can read any quote you're given, ours included, and know whether it's fair.

What air conditioning costs to run
Nearly everyone we speak to overestimates this, usually by three or four times. The picture in people's heads is an American window unit roaring away all summer. A modern split system in a Yorkshire bedroom is a very different animal.

Combi, system or conventional?
Three types, one decision, and a lot of confident advice pulling in both directions. The right answer comes down to how many people want hot water at once, and what your incoming mains is like.

What size boiler do you need?
Boiler output is quoted in kilowatts and the instinct is that more must be safer. It isn't. An oversized boiler cycles on and off, wears itself out, and costs more to run.

Repair it, or replace it?
Nobody wants to be sold a new boiler by the person who came out to fix the old one. Here's how to judge it for yourself.

Does air conditioning heat a room?
Yes. And for a lot of UK households that turns out to be the more useful half of the year. A reverse-cycle split system is, technically, an air-to-air heat pump.
