Leeds postcodes we cover for boiler installation
Mr Reactive is a West Yorkshire heating company headquartered in Bradford. We're upfront about this: we don't run a separate Leeds high-street branch, and we won't list a Leeds address we don't actually work from. What we do have is a team of in-house, Gas Safe registered engineers who install new boilers across every Leeds postcode — from LS1 in the city centre out to LS28. Bradford sits around 20 minutes from Leeds on the A647 and M621, so your free survey is usually booked within 24 hours of your enquiry and the installation follows within 24–48 hours.
We install new combi, system and conventional boilers throughout Headingley, Hyde Park, Burley, Woodhouse, Meanwood, Chapel Allerton, Chapeltown, Moortown, Alwoodley, Roundhay, Oakwood, Adel, Shadwell, Horsforth, Cookridge, Rawdon, Yeadon, Guiseley, Pudsey, Farsley, Calverley, Bramley, Kirkstall, Armley, Beeston, Holbeck, Hunslet, Harehills, Morley, Rothwell, Garforth, Cross Gates, Seacroft, Wetherby and Boston Spa. Our engineers know the Leeds housing stock — the Victorian back-to-back and through terraces of Harehills, Beeston and Holbeck, the red-brick student HMOs of Headingley, Hyde Park and Burley, the 1930s semis of Moortown, Oakwood and Adel, the period stone houses around Horsforth, and the new-build estates of east Leeds. Whichever LS postcode you live in, your installation is carried out by the same in-house team — never a subcontractor.
We also build new boiler installation pages for the rest of West Yorkshire — see our new boiler installation hub or our Boiler Installation Bradford page.

What affects a boiler installation quote in Leeds?
Our advertised installations start from £1,950. A written quotation confirms the model and the work included for your property. The final cost can change with the boiler type, hot-water demand, controls, pipework, flue route and whether the boiler is moving to a new position.
Tell us about the existing system and any current faults when requesting your survey. Agree the complete installation scope, price and available date before work starts.
Compare written boiler installation quotes
Ask each installer to quote for the same boiler model, controls and installation scope. Check the final price, any exclusions, warranty conditions, removal arrangements and who to contact for aftercare. A national or local company may propose different equipment and work, so the headline figure alone is not a like-for-like comparison.
Mr Reactive provides a written quote before the installation is agreed. Our Gas Safe registration is 598381, and we are accredited with Worcester Bosch, Vaillant, Ideal, Baxi, Vokèra and Potterton. Confirm the chosen model, warranty and available installation date with our team.

Boiler sizing — why a bigger boiler isn't always better
One of the most common installation mistakes in Leeds homes is oversizing the boiler. Homeowners (and some installers) assume that a 35kW or 40kW combi means "more hot water" — but for a typical 3-bedroom Leeds terrace or semi with 8–10 radiators, that's wildly oversized.
An oversized boiler fires at full power, overheats the radiators in minutes, switches off, and starts again — this short cycling stops the boiler ever reaching its high-efficiency condensing mode. The result: noticeably higher gas bills than a correctly sized boiler, and premature wear on the pump and valves.
An undersized boiler is the opposite problem. In a Leeds winter, when mains water enters the property at 4–6°C, an undersized combi can't heat it fast enough — leaving you with lukewarm showers and dropping pressure when two taps run at once.
Tamrez carries out a proper heat-loss calculation on every Leeds installation. We measure your mains water flow rate (a typical Leeds home needs 12–15 litres per minute for a comfortable shower), count and measure your radiators, factor in your property's age, insulation and number of bathrooms, then specify a boiler that modulates correctly for your actual demand.
For most 2-bedroom Leeds terraces — including the through-terraces of Headingley and Burley — that's a 24–28kW combi. For 3–4 bedroom semis in Moortown, Roundhay or Adel with one bathroom, 28–30kW. For homes with two bathrooms or high simultaneous demand, we'll usually recommend a system boiler with a hot water cylinder rather than a larger combi — because a 40kW combi still can't beat the simple physics of a stored-water cylinder for multi-bathroom use.
How a Mr Reactive boiler installation works in Leeds
1
Free home survey (same day or next day)
Tamrez or one of our senior engineers visits your Leeds home, usually within 24 hours of your enquiry. We measure your mains pressure and flow rate, count your radiators, check your existing flue route, gas pipe size and meter capacity, and inspect for asbestos. The survey is free and takes around 45 minutes.
2
Fixed written quote (within 24 hours)
You'll get a written quote by email with the exact boiler model, exact price, exact installation date, and a full list of what's included — no "from" prices, no asterisks. Quote valid 30 days. No deposit taken.
3
Installation day (1 working day for like-for-like)
Our team arrives between 8:00 and 8:30am with the new boiler, all parts, dust sheets and a temporary heater so your home isn't cold while we work. A typical like-for-like Worcester combi swap in a Leeds home takes 6–8 hours. We remove your old boiler, fit the new flue, install the magnetic filter, wireless thermostat and CO alarm, flush the system and commission the boiler.
4
Same-day commissioning and certification
Before we leave, the boiler is commissioned to manufacturer spec, gas-tested, and we issue your Gas Safety record, Benchmark commissioning certificate, and register your manufacturer warranty (up to 10 or 12 years depending on brand) on your behalf.
5
12 months of aftercare included
For 12 months after installation, any boiler-related callout is covered free of charge. After that, we offer a low-cost annual service plan from £10/month to keep your warranty valid for the full 10+ years.
Leeds landlord boiler installation — HMO licensing, Selective Licensing and MEES
Leeds has one of the largest private rented sectors in the country, and if you let property here your boiler decisions carry real legal weight. Any House in Multiple Occupation (HMO) with five or more occupants requires a mandatory HMO licence, and a condition of every licence is a working heating system with a valid CP12 Gas Safety record at all times — that covers a large share of the student housing across Headingley, Hyde Park, Burley and Woodhouse.
Leeds City Council has also operated Selective Licensing in designated inner-city areas, such as parts of Beeston and Harehills, which apply similar property and safety standards to ordinary rented homes. Separately, the national Minimum Energy Efficiency Standard (MEES) already bars letting a property rated EPC F or G, and the government has signalled the minimum will rise to band C later this decade. A modern A-rated combi boiler typically adds several points to an EPC score — often the difference between a D-rated and a C-rated rental.
For Leeds landlords, we offer:
- New boiler installation + CP12 + EPC-friendly controls quoted together after assessment; boiler installation packages start from £1,950 inc VAT
- Direct invoicing to letting agents or property management companies
- Tenant liaison — we'll arrange installation directly with your tenant, send before/after photos, and email the CP12 and Benchmark certificate to you the same day
- Boiler care plans from £10/month for landlords — covering the boiler, system, controls and annual CP12

Boiler installation Leeds — frequently asked questions
How much does a new boiler installation cost in Leeds?
Mr Reactive advertises boiler installations from £1,950. The final price depends on the selected boiler and the installation work required. Ask for a written quotation confirming the complete scope, any exclusions and the warranty before agreeing to proceed.
How much does British Gas charge to install a boiler in Leeds?
Installation quotes depend on the property, boiler model and work required. Ask each company for a current written quote with the same equipment and scope, including controls, flue work, removal, warranty and aftercare. Mr Reactive confirms its own final price after assessment; another company's price cannot be established from a general comparison.
Why is BOXT so cheap compared to British Gas?
Installation quotes depend on the property, boiler model and work required. Ask each company for a current written quote with the same equipment and scope, including controls, flue work, removal, warranty and aftercare. Mr Reactive confirms its own final price after assessment; another company's price cannot be established from a general comparison.
How much is a new boiler for a 3 or 4-bedroom house in Leeds?
Our listed combi packages range from £1,950 to £3,100 including VAT. For a 3- or 4-bedroom home, hot-water demand and the existing system determine the suitable boiler. The final price depends on boiler type, brand and whether any pipework or relocation is needed. Mr Reactive gives a fixed written quote after a free survey — combi swaps from £1,950.
What's the best month to replace a boiler in Leeds?
May to August is the cheapest and fastest time to install a new boiler. Heating engineers are quieter through summer, you can typically book within 48 hours, and some installers offer summer discounts. Avoid October to January if you can — winter demand pushes prices up and waiting times to 2–3 weeks.
Is it worth replacing a 15-year-old boiler in Leeds?
Almost always yes. A 15-year-old boiler typically runs at 70–80% efficiency, and older units lower still, while a modern A-rated condensing boiler runs at 92–94%. A Leeds household spending around £1,400 a year on gas can save £300–£400 a year with a new boiler — with actual savings and payback depending on energy use, tariffs and the installation cost.
Is there a government scheme to replace old boilers?
The main scheme is the government's ECO4 (Energy Company Obligation), which can fund a replacement boiler for homeowners on certain income-related benefits. The Boiler Upgrade Scheme funds heat pumps rather than gas boilers. Eligibility is limited — Mr Reactive runs an ECO4 funding service and can check if you qualify; if you don't, our boiler installation packages start from £1,950 inc VAT, with the final scope confirmed in writing.
Which combi boilers should I avoid?
Choose a boiler that suits the property, hot-water demand, warranty requirements and installation budget. Our current packages include Worcester Bosch, Baxi, Ideal and the Vokèra Easi-Heat i 29C budget option for landlords. We confirm suitability and the complete scope in a written quote.
Do I need a 25kW or 30kW combi boiler?
It depends on your hot-water demand, not the size of the house. A 24–28kW combi suits most 2–3 bedroom Leeds homes with one bathroom. A 30–35kW combi is for homes with higher simultaneous hot-water demand. Bigger is not better — an oversized combi short-cycles and costs more to run. We carry out a heat-loss and flow-rate calculation on every survey to size it correctly.
How long does it take to install a new boiler in Leeds?
A like-for-like combi swap takes 1 working day (6–8 hours). Changing boiler type, such as a back boiler to a combi, takes 2–3 days. Relocating the boiler to a different room adds half a day. We start at 8:00–8:30am and you'll have heating and hot water by early evening.
Do you provide a Gas Safety Certificate after installation?
Yes. Every Mr Reactive installation includes a Gas Safety record (CP12), a Benchmark commissioning certificate completed and signed in your boiler manual, and manufacturer warranty registration on your behalf. All three are emailed to you the same day and the paper copies left at the property.
What is included in my boiler installation quote?
The boiler, flue, magnetic system filter, wireless room thermostat, CO alarm, manual system flush, removal of your old boiler, commissioning, Benchmark certificate, Gas Safety record, and up to 12-year manufacturer warranty registered on your behalf. The exact scope, any additional work and model-specific warranty conditions are confirmed in your written quote.
