Climateway

Whole-home climate adaptation

Warm winters. Cool summers. Lower bills.

We design and install complete climate systems for British homes — heating, cooling, ventilation, controls — as one managed project.

Our installation standards

Every Climateway installation partner is MCS certified. Cooling installations are completed by F-Gas certified engineers. All projects are designed to PAS 2035 whole-house retrofit standards.

Every installation comes with our three-part Climateway Cover — product, workmanship, and insurance.

How Climateway works

One designed system. Built for every season.

Whole-home design

We assess your house as a system — fabric, heating, cooling, ventilation, controls — not as a list of separate measures. Every recommendation is engineered against the others.

Year-round comfort

Engineered for warm winters and cool summers. Most retrofit projects only solve half the problem. We solve both.

Comfort, guaranteed

We design every system to deliver agreed comfort temperatures in both seasons. If our installation doesn't hit those temperatures, we come back at our cost until it does. No other UK climate company offers this.

The Boiler Upgrade Scheme now covers cooling.

Until this year, government grants only supported heating upgrades. From 2026, the Boiler Upgrade Scheme extends to air-to-air heat pumps — the same units that warm your home in winter and cool it in summer.

Climateway projects qualify for up to £7,500 on traditional heat pumps and £2,500 on air-to-air systems, alongside Warm Homes Plan grants and other support. Most clients see grants of £5,000 to £15,000 on a complete climate adaptation project.

    System Design

    We design your complete climate system, model your savings, identify every grant you qualify for, and give you a fully fixed, written installation price. Once you accept it, that's what you pay. If anything comes up during installation that's our fault to have missed, we cover it. £1,500 fixed design fee. No obligation to proceed.

Why Climateway

Most companies sell one thing. We design the whole system.

Single-product installers

  • Heat pumps OR cooling OR insulation, never together
  • Tied to one energy supplier or manufacturer
  • You coordinate three or four contractors yourself
  • You miss grants by sequencing wrong

Climateway

  • One integrated system: heat, cool, fabric, controls
  • Independent — no supplier or manufacturer ties
  • One designed project, one team, one invoice
  • Every grant identified and applied for you

Frequently asked

Everything homeowners want to know.

From your audit to a finished installation, typically: — Climate Ready: 8 to 14 weeks — Climate Complete: 12 to 20 weeks — Climate Estate: 16 to 28 weeks Most of that time is design and approvals. The physical installation usually takes 1 to 3 weeks on site. Listed buildings, conservation areas, ground-source projects and complex period properties can take longer — we tell you upfront if your project falls into this category.

No. We design the full system but installation can be staged across phases if needed. We'll recommend a sequence that protects your savings target.

The two main grants are the Boiler Upgrade Scheme, which provides £7,500 toward a heat pump installation (or £2,500 for air-to-air systems), plus zero-rated VAT on all energy-efficient home upgrades. Lower-income households may also qualify for the Warm Homes: Local Grant. Your Climate Score identifies exactly what your home qualifies for. We apply for the grants on your behalf — you don't deal with any paperwork.

A climate-ready home commands a meaningful premium. Most of our completed projects add more in value than they cost. We'll show you the projected resale uplift in your design.

Yes. We routinely partner with architects on refurbishments and extensions. Talk to us early and we'll integrate.

Every installation carries a 6-year workmanship guarantee, underwritten by an independent insurer, plus manufacturer product warranties of 5 to 10 years. On top of that, our Comfort Promise: if your designed system doesn't deliver the agreed indoor temperatures in winter or summer, we come back and fix it at our cost. You only ever deal with Climateway, not the installers. We manage every contractor on your behalf. Full details on our /guarantees page.

We model your projected savings using your home's design and current energy prices, and we share that modelling with you transparently before you sign. But your actual bills depend on factors outside our control — your energy tariff, how you use the system, weather, and energy market prices. We commit to designing the most efficient system possible for your home, and to delivering the comfort temperatures we agree. We can't guarantee a specific bill outcome and no honest installer can.

Installers. Real engineering, real equipment, real homes. We don't sell offsets or carbon credits. Your savings come from your home actually using less energy.
