I found Louis Smith, and Heat in London to be genuine, hard working and skilled heating engineers. They were very competitively priced, did what they said and made an excellent job of converting my old system to a new Combi boiler and relocating it to a more suitable location. Easy to communicate with, explained what they were doing and listened to what the customer wanted. Prompt and tidy and took care of the property they are working in. I will definitely use them again.

Louis and his team came to our rescue when our underfloor heating system failed to work properly. Kept us informed every step of the way and always happy to answer our questions. Would definitely recommend and use his services in the future

Louis and his team of plumbers were amazing, I was left in the lurch by my builder and Louis came to my rescue, re-doing all the bad plumbing work the contractor had left in his wake. I now have a lovely warm house. Cannot recommend Louis and the boy’s enough, they were hard working, polite and clean. Will definitely use Heat in London for all my future plumbing needs.

I had a radiator fitted today by heat in London. Lewis and rob carried out a first class job. Both were punctual, professional, polite and friendly. They left my room clean and tidy before they left. I’m so pleased with my new radiator. Thanks guys. Real service with a smile. Highly recommend this company.

Had a disaster this evening, sprung a leak under the sink upstairs, water coming through the ceiling. Phoned Louis at Heat in London, sent him photos & video of issue. He advised what to do & I was able to fix the problem my self. I wouldn't hesitate to use Heat in London again if I needed work done. This is the 4th time I've used their service, Louis is friendly, professional prompt and extremely helpful and I would whole heartedly recommend them.

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.
