Elliot Ritchie
Castle Climate Control have worked on my home since 2016 and I’ve always had a great experience with them. They’ve installed an air source heat pump, hot water cylinder, air conditioning, room thermostats to control underfloor heating, and they service everything every year (including an existing solar thermal system). Karl and his team are polite, professional and respectful of your home, with great attention to detail. I trust them and have a lot of respect for how they work. Highly recommended.
Spring Charity
Karl and his team installed two air conditioning units at The Spring Charity and kindly donated their labour for free! They have done an excellent job and are an example to other businesses on how to practically support small charities! Thank you so much Karl for your generosity and excellent work! I would highly recommend Castle Climate Control Ltd to other organisations, companies or for your home! Our teaching kitchen will. I longer be like working in an oven! 🤩🌟

Very impressed with the service and reliability of Castle Climate Control. Had my annual heating service which was carried out by Steve. Professional polite and gave some good advice on running my system, which included turning my heating down a notch to save energy. Steve is a credit to the company with his knowledge on Air to heat source systems. Highly recommended company I would not use anyone else 5 stars ⭐⭐⭐⭐⭐ Thank you !

Karl is outstanding, during difficult period of this year he went above and beyond for me to help me out with a dishwasher replacement. I couldn’t be more grateful for his help, he was tidy, hygienic and professional just as lockdown started to ease and he was able to help me after 8 weeks with no dishwasher!

Frequently asked questions
How do I know you’re properly qualified and certified to install heat pumps?
We are MCS‑certified and registered with an approved consumer protection/competent person scheme, which is essential for quality assurance and to access grants like the Boiler Upgrade Scheme (BUS).
Can you tell me if a heat pump is actually suitable for my home?
We carry out a detailed home assessment, including property type, insulation levels, existing heating system and available outdoor space, to confirm whether a heat pump is a good fit.
What type and size of heat pump will you recommend for my property, and why?
We design the system using a heat‑loss calculation for your home, then match the correct kW size and model (for example, air‑source vs ground‑source) so it runs efficiently and reliably.
What will the full installation cost be, and what’s included in your quote?
Our fixed quote clearly lists the heat pump, cylinder, controls, labour, scaffolding (if needed), electrical work and any radiator or pipework upgrades, so you know exactly what you’re paying for.
Can you help me access government grants like the Boiler Upgrade Scheme?
Yes, as an MCS installer we can confirm your eligibility, apply for the BUS grant (worth up to £7,500) on your behalf and deduct it directly from your quote.
How much disruption should I expect during installation, and how long does it take?
A typical air‑source heat pump installation takes around 2–5 days, and we’ll agree locations for the indoor and outdoor units, manage any planning considerations and keep you informed each day.
Will I need to replace my radiators or upgrade anything else in my home?
After the heat‑loss survey, we’ll advise if any radiators, pipework, electrics or hot‑water cylinder need upgrading so the system can run efficiently at lower flow temperatures.
How noisy is the outdoor unit and where will it be installed?
Modern heat pumps are designed to be quiet and must meet UK noise regulations; we’ll position the unit to minimise any impact on you and your neighbours and comply with local planning rules.
What warranties, servicing and aftercare do you provide?
You’ll get manufacturer warranties on the heat pump plus our workmanship guarantee, and we offer ongoing servicing and support to keep your system performing at its best.
What running costs and savings can I realistically expect compared to my current boiler?
We’ll estimate your likely annual running costs and potential savings based on your current fuel type, insulation level and tariffs, using real‑world performance data rather than lab figures.
