Yes. On top of your statutory rights, every job comes with a 6-month workmanship guarantee from completion, covering defects in the workmanship. Manufacturer warranties on boilers and products are separate.

No. We work on gas boilers of all types, including combi, system and regular boilers, but we do not work on oil boilers.

It varies between manufacturers, but is usually 5, 7 or 10 years.

Nine times out of ten it will take one day if you already have a combi boiler. Changing the boiler type or moving it to a new position can take longer, and you will be told the timescale before the job is booked.

Most new boiler installations cost between £2,000 and £3,000 supplied and fitted. The final price depends on the boiler, its position and any upgrades your system needs, and you get a clear quote before any work starts.

Usually only for the day of the swap. The old boiler is removed, the new one is fitted and commissioned, and in most cases your heating and hot water are back on before we leave.

Removal and disposal of the old boiler can be included in your quote. Just mention it when you get in touch.

Certain parts of a service, like cleaning the heat exchanger, can improve efficiency, but a service is mainly for safety and for testing that the boiler is working correctly.

Every 12 months, to keep it safe and to keep the manufacturer warranty valid.

A boiler service costs £85 to £120, depending on the boiler type and access.

We check the burner, gas pressure, seals, condensate and safety devices, test the flue gases with a calibrated analyser and clean parts where needed.

You are told straight away what the problem is and what it will cost to fix. No extra work is carried out without your agreement.

Yes. LAB Boiler Care is a membership at £12.99 a month. It includes your annual boiler service, priority booking, 50% off call-out fees for breakdown and diagnosis visits, and WhatsApp support for quick advice and fault diagnosis before a visit. Your boiler has a short eligibility inspection first. Full terms apply, and details are available on request.

It depends on the size, layout and complexity of the bathroom, but it is usually around 7 days of labour.

Bathroom installations are typically £3,000 to £5,000. You get a clear scope and price before any work begins. Anything unexpected found once work starts is explained and agreed with you before it goes ahead.

Yes. We handle the strip-out and all the plumbing and fitting, and manage our own subcontractors for tiling, plastering, electrics and joinery or flooring, so you have one point of contact.

Yes. You can choose and buy your own suite, or we can recommend products that suit your space and budget.

We plan the job to keep disruption to a minimum. If you only have one bathroom, mention it at the quote stage and we will explain how the work will be staged.

Allow about an hour per radiator if it stays in the same place with little or no pipework change.

Most radiator installations cost £150 to £300 per radiator, depending on the radiator and whether the pipework needs moving.

Yes. We fit standard panel radiators, vertical and horizontal designer radiators and heated towel rails in black, anthracite, white and brushed brass finishes.

Yes. Moving a radiator means altering the pipework, so it takes longer than a like-for-like swap. We will price this clearly before starting.

Often, yes. We flush radiators and whole heating systems to clear sludge, either as a standalone job or alongside radiator work, and we can advise whether a flush would help your heating run better.

Yes. We fit new TRVs and replace old ones, either with a new radiator or as a job on its own, so you can control the temperature in each room.

Most repairs come to £100 to £500. There is a £75 call-out and diagnostic fee, which covers the first hour of labour; any parts needed are charged on top, and you are told the price before they are fitted.

We repair combi, system and regular gas boilers. We do not work on oil boilers. Tell us the make and model when you get in touch.

Call or WhatsApp with the boiler make and the fault or error code, and we will arrange the earliest visit we can, 7 days a week.

Yes. Once the fault is found, you are told what is needed and what it will cost before anything is fitted.

It depends on the age and condition of the boiler and the fault. If a repair no longer makes sense, we will tell you honestly and give you a clear quote for a replacement, so you can decide.

Yes. Members of the LAB Boiler Care plan get 50% off call-out fees for breakdown and diagnosis visits, along with priority booking. Ask us for details.
