How much does it cost to rewire a two-bedroom bungalow in 2026?

A two-bedroom bungalow rewire in 2026 typically costs between £3,000 and £4,200. This includes a new consumer unit with RCBOs and SPD, new lighting and power circuits throughout, kitchen and bathroom circuits, smoke and heat detection, bonding, full testing to BS 7671, and an Electrical Installation Certificate. The exact price depends on the number of socket outlets and light points, the condition of the existing installation, and regional labour rates.

Is a bungalow cheaper to rewire than a house?

Generally yes, when comparing like-for-like room counts. A bungalow is typically cheaper to rewire than a two-storey house with the same number of bedrooms because all cable runs can be made from the loft void above. There are no first-floor floorboards to lift, no cables to run between storeys, and the electrician can work from a single level. This saves significant labour time. However, a large four-bedroom bungalow may cost more than a small two-bedroom house simply due to the greater number of circuits and longer cable runs.

How long does a bungalow rewire take?

A two-bedroom bungalow typically takes 4 to 6 days for first fix and second fix combined. A three-bedroom bungalow takes 5 to 8 days. A large four-bedroom bungalow with extensive outbuildings or a detached garage may take 7 to 10 days. The single-storey layout and loft access generally make bungalow rewires faster than equivalent-sized houses.

Can I live in the bungalow during a rewire?

Yes, it is possible to stay in the bungalow during a rewire, though there will be disruption. The electrician can maintain temporary power to areas not being worked on. The first fix phase is the most disruptive — walls may need channelling, and there will be dust and noise. If you can stay elsewhere for the first fix phase (3 to 5 days), the work will proceed faster. Many bungalow residents are elderly, so the electrician should plan the work to minimise disruption and maintain access to essential facilities.

Do bungalows often need rewiring?

Many bungalows in the UK were built in the 1950s, 1960s, and 1970s and have never been rewired. These properties commonly have rubber or PVC-sheathed cables that have deteriorated, rewirable fuse boards with no RCD protection, and inadequate earthing arrangements. If your bungalow has not been rewired in 30+ years, or if an EICR has identified serious deficiencies, a rewire is strongly recommended.

What about the garage and outbuildings?

Many bungalows have attached or detached garages, sheds, or workshops with their own electrical supply. Rewiring these is additional work. A garage supply typically costs £300 to £800 depending on whether a new SWA (steel wire armoured) cable needs to be run underground from the consumer unit. Each outbuilding circuit needs its own RCD protection and may require a small distribution board.

Will I need to redecorate after a bungalow rewire?

Some redecoration is usually needed, but bungalows with loft access require less channelling than houses. Many cable runs can be made through the loft void and dropped down to accessories, reducing the amount of wall chasing. Budget approximately £800 to £2,000 for plastering and redecoration after a bungalow rewire, depending on the extent of surface work required.

Key Takeaways

1A bungalow rewire in the UK typically costs between £3,000 and £6,000 depending on the size, number of rooms, and complexity of the installation.
2Bungalows are often easier and quicker to rewire than two-storey houses because all cable runs are accessible from the loft void above, eliminating the need to lift first-floor floorboards.
3A two-bedroom bungalow rewire averages £3,000 to £4,200; a three-bedroom bungalow £3,800 to £5,200; and a large four-bedroom bungalow £4,500 to £6,000.
4Regulation 411.3.3 of BS 7671 requires 30mA RCD protection on all socket outlet circuits up to 32A, bathroom circuits, and circuits supplying equipment outdoors.
5Many bungalows are occupied by older residents and may have very old wiring (1960s or 1970s) — rubber-sheathed cables, rewirable fuses, and no RCD protection are common findings.

Why Rewire a Bungalow?

A bungalow rewire replaces all electrical wiring, accessories, and the consumer unit with a modern installation compliant with BS 7671:2018+A4:2026. Many bungalows in the UK were built in the post-war period and have original wiring that is now 50 to 70 years old — well beyond its serviceable life.

Common issues found in older bungalows include rubber-sheathed or lead-sheathed cables with degraded insulation, rewirable fuse boards with no RCD protection, inadequate earthing (particularly TT systems with old earth rods), and insufficient socket outlets leading to overloaded extension leads. An EICR on a 1960s bungalow commonly returns multiple C2 (potentially dangerous) observations.

The good news is that bungalows are typically easier to rewire than two-storey houses. The single-storey layout means all rooms are accessible from the loft void, making cable runs straightforward and reducing the amount of disruptive wall chasing.

Labour and Timescales

Bungalow rewires benefit from the single-storey layout. All cable runs can be made through the loft void and dropped down through the ceiling to wall-mounted accessories. This significantly reduces the need for wall chasing compared to a two-storey house.

First fix (cable installation) — 3 to 6 days depending on bungalow size. Most cable runs via the loft void, with minimal wall chasing.
Second fix (termination and testing) — 1 to 3 days. Installing accessories, connecting the consumer unit, and testing every circuit.
Electrician day rate — £250 to £400 depending on region. Most bungalow rewires are quoted as a fixed price.

05 · Cost Guide

Bungalow-Specific Advantages for Rewiring

Bungalows have several characteristics that make them generally easier and cheaper to rewire per room than two-storey houses:

Loft access — all rooms have a ceiling with loft void above, allowing cables to be run freely without lifting floorboards.
No inter-floor cable routes — there are no cables to run between ground and first floors, eliminating one of the most time-consuming aspects of house rewires.
Reduced wall chasing — cables can drop from the loft to accessories with only short vertical chases in the wall, reducing disruption and redecoration costs.
Single consumer unit location — no need for sub-distribution boards on upper floors, keeping the installation simple and cost-effective.

Factors Affecting Price

Loft insulation — thick loft insulation can slow cable runs and requires careful routing to maintain fire safety. Cables must not be buried in thermal insulation without appropriate derating.
Earthing arrangement — many older bungalows have TT earthing with an earth rod. If the earth electrode resistance is too high, a new earth rod or upgrade may be needed.
Outbuildings — a detached garage, workshop, or garden office requiring a new SWA supply adds £300 to £800 per outbuilding.
Additional circuits — EV charger, solar PV, underfloor heating, or electric cooking appliances each require dedicated circuits.
Location — regional labour rate variation of 15% to 30% between London/South East and northern England.

07 · Cost Guide

Regulations and Certification

A bungalow rewire is notifiable under Part P of the Building Regulations. The electrician must be registered with a competent person scheme (NICEIC, NAPIT, ELECSA) to self-certify the work.

Key requirements under BS 7671:2018+A4:2026 include: Regulation 411.3.3 requiring 30mA RCD protection on socket circuits up to 32A, bathroom circuits, and outdoor circuits; Regulation 421.1.201 requiring a non-combustible consumer unit enclosure; and Regulation 443.4 requiring a risk assessment for SPD installation (almost always resulting in SPD being fitted).

An Electrical Installation Certificate (EIC) must be issued upon completion, covering the design, construction, inspection, and testing of the entire new installation.

For Electricians: Quoting Bungalow Rewires

Bungalow rewires are among the most straightforward domestic rewire jobs. The loft access and single-storey layout make them quicker and more predictable than house rewires.

Loft Survey Is Key

Always inspect the loft during your survey. Check headroom, insulation depth, existing cable routes, and the condition of any existing wiring. Good loft access makes the job profitable; poor access (low headroom, no boarding) slows you down.
