Lacey Heating are superb. We’ve used the team for several years and they’ve always delivered excellent work. They’re professional, knowledgeable, and dependable. Most recently, Tony helped us out of hours, when they were closed, with a historic issue, and without him we would have been without water for several days, with young children at home. To me, the two things that matter most with a plumber are simple: 1) you trust them to do the job properly, and 2) you know they’ll be there when you’re in trouble. Lacey Heating excel at both. Highly recommended.

I had water coming through kitchen ceiling, Tony quickly identified the cause and rectified the issue. Later on I had a new boiler installed which comes with a 10 year warranty. Everything was fairly priced, great responsive service, helpful office staff and knowledgable and very friendly plumbers. Very clean and tidy too which is always appreciated! Seamless service, thanks all for your help.

Legends Tony visited to assess a new boiler install on the Thursday, it’s a period property which comes with unique difficulties. On learning my current boiler was out, he made moves to help me out and had his team over the next morning. Jake and Luke were bang on time in the morning and the whole team were a pleasure to host from assessment to finish. Was honestly made up with the whole process. The install was very tidy and they even connected to my Nest thermostat. True Gems, fully recommend.

Lacey Heating refurbished my bathroom - swapped my bath for a walk-in shower, changed the lighting, fitted a new cabinet and basin, plastered the ceiling, tiled the walls and installed a fan. The team of Luke and Matt did a completely fabulous job. They always turned up on time, always left everything tidy, dealt with any hiccups quickly and professionally, made sure I was informed throughout and talked me clearly through any decisions I needed to make. I would have them work in the house again without hesitation and would very happily recommend them.

I would highly recommend the Lacey heating team. I received such fast and friendly replies via email from Lucy and Jayne. I had a new tap installed and the engineers were so professional and friendly, answering any questions I had with such patience. Thank you so much to Paul for this especially. I will be using them time and time again, thank you so much team.

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).
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.
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.
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.
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.
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.
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.
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.
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.
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.
