Boiler Installation Nottingham: Compare Quotes

Most Nottingham homes that get a new boiler are swapping an old gas model for a newer one. The choice is rarely gas or nothing, but it is worth knowing your options. Terraces and semis make up about 60% of households in the city, and each type points to a different boiler.

Questions to ask every installer

What output is the boiler, and how did you work it out? A good installer bases it on heat loss and hot water demand, not on the old boiler's label.

Will you clean the system and fit a magnetic filter? Old sludge kills new boilers.

What scale protection will you fit? Severn Trent's latest results show the city zone at about 227 mg/l of calcium carbonate, so ask whether the manufacturer's warranty needs it.

Are you notifying the job to Building Control through Gas Safe? You should receive a certificate within weeks.

Flats need special care

About 23.5% of Nottingham households live in flats. In a purpose-built block, the flue may need to rise through a shared duct or exit a wall over a walkway, and there are strict rules on clearances. Leaseholders should check the lease and get the freeholder's consent before work starts.

In warehouse conversions in the Lace Market, a long horizontal flue run can limit which boiler models will fit.

Should it be gas at all?

If your house has a garden and decent insulation, ask for a heat pump quote alongside. The £7,500 Boiler Upgrade Scheme grant can bring the price near a premium boiler. For a Nottingham semi, our air source heat pumps guide sets out how running costs compare.

Nottingham homes and what they need

Victorian terraces

A combi usually fits in the kitchen. If the boiler is moving, check the new flue position doesn't sit under a neighbour's window.

Interwar and post-war semis

Two bathrooms or a busy family point to a system boiler with an unvented cylinder, which keeps good flow when two taps run at once.

City-centre flats and warehouse conversions

Some blocks don't allow gas at all. If you are on electric heating, ask about modern storage heaters or an air-to-air heat pump instead.

Areas covered

Questions people in Nottingham ask

How long does a boiler swap take?

A like-for-like combi swap is usually one day. Moving the boiler, converting from a regular system to a combi or adding a cylinder can take two or three days.

Do I need to tell anyone?

Your installer notifies Building Control through Gas Safe. Leaseholders should also tell the freeholder, and landlords should update the gas safety record.
