Who we help
For homeowners
Boiler servicing, repairs and new installations, general plumbing, bathroom design, underfloor heating and straightforward advice on the right heating for your property — including whether an air source heat pump makes sense for you.
No job is too small. A routine boiler service gets the same care and attention as a full system design.
For residential developers
Heating system design and installation for new-build homes and residential developments: underfloor heating, air source heat pumps and energy-efficient systems, designed around your project requirements.
We support projects from initial design and specification through to installation, including multi-property and phased development work, coordinating with your project team throughout.

Every plumbing requirement from design to installation: full bathroom suites, wet rooms, utility rooms and water softeners, including tiling, electrics and decorating where needed.
Custom-built vented, unvented and thermal store cylinders, with solar coils and spare ports for future heat sources.
Designed and installed for over a decade. Even warmth, no radiators, and running costs cut by up to half.
Stoves and boiler stoves that heat the room and the house, integrated with thermal stores and your existing system.
Bespoke systems that combine boiler, solar, stove and heat pump, keeping your boiler in condensing mode for peak efficiency.
Heating systems designed around your specification: underfloor heating, air source heat pumps and high-efficiency boilers, engineered for the homes you're building rather than lifted from a catalogue.
Installation across multiple plots and phases, scheduled around your build programme and coordinated with your site and project teams from first fix to commissioning.
Involvement from initial design through to installation: heat-loss led specification, energy-efficient and renewable options, and direct access to the engineers doing the work.
Evoheat is run by father-and-son team Lloyd and Leo Wright, heating engineers with 45 years of combined experience around Essex. The firm is family-run on purpose: the people who design your system are the people who install it.
That design-first approach is why Evoheat systems run cheaper. Every install, from a straightforward combi swap to a phased new-build development, is engineered to keep the boiler working in condensing mode, where it is at its most efficient.
With Lloyd and Leo personally involved in the business, clients benefit from direct communication, experienced advice and a consistent standard of workmanship — from individual homes to larger residential projects.
“Designing a bespoke system that achieves the most effective and efficient result for our clients is something I am passionate about.”

How it works
Call, email or send the form. Tell us what needs doing, whether that's a broken boiler, a whole-house system or a new-build development.
Lloyd or Leo looks at your property, or your plans and specification, then designs around them. The people who design the job are the people who install it.
We confirm what your system can take before quoting, so the price reflects the actual job rather than a guess.
Fitted cleanly and tidily, with pipework you'd be happy to have on show. The photos below are all our own work.
Annual servicing and maintenance to keep boilers, stoves and multi-fuel systems running at their best.
Recent work
From single homes to developments
500 square metres of home and commercial space moved off LPG onto a 60kW log gasification boiler feeding underfloor heating and five bathrooms. With locally sourced wood, heating bills fell from £7,000 a year to almost nothing.
A 1,000 square metre new-build care facility with 36 wet rooms. Four condensing boilers, two floors of underfloor heating, solar thermal and weather compensation. The building now runs at half its originally estimated cost.
A rural new build running underfloor heating from a gas condensing boiler with weather compensation, tuned so well the boiler barely works in summer.
We work across Essex and the surrounding areas from our base in Fobbing. Recent jobs include Basildon, Southend, Brentwood, Chelmsford, Rayleigh and Horndon-on-the-Hill.
Yes. We look at your property and confirm what your system can take before quoting, so the price reflects the actual job.
Yes. We design and install heating for new-build homes and residential developments, including underfloor heating, air source heat pumps and energy-efficient systems. We can be involved from initial design and specification through to installation, including multi-property and phased work.
Selected gas condensing boilers we fit carry a 5 year parts and labour guarantee, and many of our cylinders carry guarantees of 25 years and over.
Most roofs are structurally fine to carry the panels. A southwest to southeast aspect is ideal, but easterly and westerly roofs still work reasonably well. Most installations need 4 to 6 square metres of roof space.
Most boilers are compatible with solar thermal, though many combination boilers can be a problem. We will confirm what your system can take before quoting.
Your hot water bill can be reduced by up to 70%, and a well-fitted system can add value to your house. It is also a very cost-effective way to heat a swimming pool.
Not generally, although there can be issues with listed buildings. We will flag anything that needs checking before work starts.
It depends on style and on whether the stove just heats its room or also feeds a boiler for your heating and hot water. Options run from contemporary designs to multi-sided viewing models, and we will advise on what suits your home.
That depends on the room it sits in and what the boiler side needs to feed. We calculate both and specify the right output for you.
