Roger FURNELL
A stress free experience from quotation visit to completion. Two very competent and hard working chaps were with us for 3 days and did an excellent job. Friendly without being over chatty, highly skilled and tidy, they made good beyond our expectations. The price quoted was significantly lower than other quotes. I would recommend Lewington very highly indeed.
Alan Dunn-Birch
Lewington removed our gas boiler etc. and installed an Air Source Heat Pump, new cylinder, radiator and associated pipe work and electrics. Incredibly efficient, professional and super-clean work and a great experience end to end!! Darren was superb through. 100% recommended.

Excellent and friendly service! Had an issue with my boiler and the team fixed it quickly. Highly recommended 😊

We are in the process of having GSHP commissioned by Lewington’s. I chose them because out of all the companies I engaged with, Lewington’s were able to provide references and took me on a site visit to see a previous installation. Furthermore, I noticed that Lewington’s have a long-standing tradition of taking on apprentices. This gave me confidence that, if this company is serious about training, nurturing young talent and promoting from within whilst maintaining extremely high standards, then they would nurture my particular project with just as much care and diligence. Thank you, Darren, Matt, Zach and Toby, for a first-class job and happy for you to show-off your work here to your other clients for GSHP.

Another professional and reliable service from this excellent company. Kept my boiler system working well for years. Can't thank and recommend them enough. Special mention to Rob, an employee simply a credit to his company, friendly, on time, courteous and tidy, what more can you ask for. Big thanks.

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.
